20th Century Richard Falckenberg EnglishGERMAN PHILOSOPHY SINCE THE DEATH OF HEGEL.
With Hegel the glorious dynasty which, with a strong hand, had guided the fate of German philosophy since the conclusion of the preceding century disappears. From his death (1831) we may date the second period of post-Kantian philosophy, which is markedly and unfavorably distinguished from the first by a decline in the power of speculative creation and by a division of effort. If previous to this the philosophical public, comprising all the cultured, had been eagerly occupied with problems in common, and had followed with unanimous interest the work of those who were laboring at them, during the last fifty years the interest of wider circles in philosophical questions has grown much less active; almost every thinker goes his own way, giving heed only to congenial voices; the inner connection of the schools has been broken down; the touch with thinkers of different views has been lost. The latest decades have been the first to bring a change for the better, in so far as new rallying points of philosophical interest have been created by the neo-Kantian movement, by the systems of Lotze and Von Hartmann, by the impulse toward the philosophy of nature proceeding from Darwinism, by energetic labors in the field of practical philosophy, and by new methods of investigation in psychology.
%1. From the Division of the Hegelian School to the Materialistic Controversy.%
A decade after the philosophy of Hegel had entered on its supremacy a division in the school was called forth by Strauss's Life of Jesus(1835). The differences were brought to light by the discussion of religious problems, in regard to which Hegel had not expressed himself with sufficient distinctness. The relation of knowledge and faith, as he had defined it, admitted of variant interpretations and deductions, and this in favor of Church doctrine as well as in opposition to it. Philosophy has the same content as religion, but in a different form, i.e., not in the form of representation, but in the form of the concept--it transforms dogma into speculative truth. The conservative Hegelians hold fast to the identity of content in the two modes of cognition; the liberals, to the alteration in form, which, they assert, brings an alteration in content with it. According to Hegel the lower stage is "sublated" in the higher, i.e., conserved as well as negated. The orthodox members of the school emphasize the conservation of religious doctrines, their justification from the side of the philosopher; the progressists, their negation, their overcoming by the speculative concept. The general question, whether the ecclesiastical meaning of a dogma is retained or to be abandoned in its transformation into a philosopheme, divides into three special questions, the anthropological, the soteriogical, and the theological. These are: whether on Hegelian principles immortality is to be conceived as a continuance of individual existence on the art of particular spirits, or only as the eternity of the universal reason; whether by the God-man the person of Christ is to be understood, or, on the other hand, the human species, the Idea of Humanity; whether personality belongs to the Godhead before the creation of the world, or whether it first attains to self-consciousness in human spirits, whether Hegel was a theist or a pantheist, whether he teaches the transcendence or the immanence of God. The Old Hegelians defend the orthodox interpretation; the Young Hegelians oppose it. The former, Göschel, Gabler, Hinrichs, Schaller (died 1868; History of the Philosophy of Nature since Bacon*, 1841 seq.), J.E. Erdmann in Halle (1805-92; Body and Soul, 1837; Psychological Letters, 1851, 6th ed., 1882; *Earnest Sport, 1871, 4th ed., 1890), form, according to Strauss's parliamentary comparison carried out by Michelet, the "right"; the latter, Strauss, Feuerbach, Bruno Bauer, and A. Ruge, who, with Echtermeyer, edited the Hallesche, afterward Deutsche, Jahrbücher für Wissenschaft und Kunst, 1838-42, the "left." Between them, and forming the "center," stand Karl Rosenkranz in Königsberg (1805-79), C.L. Michelet in Berlin (p. 16; Hegel, the Unrefuted World-philosopher, 1870; System of Philosophy, 1876 seq.), and the theologians Marheineke (a pupil of Daub at Heidelberg) and W. Vatke (Philosophy of Religion, edited by Preiss, 1888). Contrasted with these is the group of semi- or pseudo-Hegelians (p. 596), who declare themselves in accord with the theistic doctrines of the right, but admit that the left represents Hegel's own opinion, or at least the correct deductions from his position.
The following should also be mentioned as Hegelians: the philosopher of history, Von Cieszkowski, the pedagogical writer, Thaulow (at Kiel, died 1883), the philosopher of religion and of law, A. Lasson at Berlin, the aesthetic writers Hotho, Friedrich Theodor Vischer (1807-87), and Max Schasler (Critical History of Aesthetics, 1872; Aesthetics, 1886), the historians of philosophy, Schwegler (died 1857; History of Greek Philosophy, 1859, 4th ed., 1886, edited by Karl Köstlin, whose Aesthetics appeared 1869), Eduard Zeller of Berlin (born 1814), and Kuno Fischer (born 1824; 1856-72 professor at Jena, since then at Heidelberg; Logic and Metaphysics, 2d ed., 1865). While Weissenborn (died 1874) is influenced by Schleiermacher also, and Zeller and Fischer strive back toward Kant, Johannes Volkelt in Würzburg (born 1848), who started from Hegel and advanced through Schopenhauer and Hartmann, has of late years established an independent noëtical position and has done good service by his energetic opposition to positivism (Das Denken als Hülfvorstellungs--Thätigkeit und als Aupassungsvorgang* in the *Zeitschrift für Philosophic, vols. xcvi., xcvii., 1889-90).
The leaders of the Hegelian left require more detailed consideration. In David Friedrich Strauss (1808-74, born and died at Ludwigsburg) the philosophy of religion becomes a historical criticism of the Bible and of dogmatics. The biblical narratives are, in great part, not history (this has been the common error alike of the super-naturalistic and of the rationalistic interpreters), but myths, that is, suprasensible facts presented in the form of history and in symbolic language. It is evident from the contradictions in the narratives and the impossibility of miracles that we are not here concerned with actual events. The myths possess (speculative, absolute) truth, but no (historical) reality. They are unintentional creations of the popular imagination; the spirit of the community speaks in the authors of the Gospels, using the historical factor (the life-history of Jesus) with mythical embellishments as an investiture for a supra-historical, eternal truth (the speculative Idea of incarnation). The God become man, in which the infinite and the finite, the divine nature and the human, are united, is the human race. The Idea of incarnation manifests itself in a multitude of examples which supplement one another, instead of pouring forth its whole fullness in a single one. The (real) Idea of the race is to be substituted for a single individual as the subject of the predicates (resurrection, ascension, etc.) which the Church ascribes to Christ. The Son of God is Humanity.
; the same "for the German People," 1864 [English translation, 1865]; Christian Dogmatics, 1840-41; Voltaire, 1870; Collected Writings, 12 vols., edited by Zeller, 1876-78. On Strauss cf. Zeller, 1874 [English, 1874], and Hausrath, 1876-78.]
In his second principal work Strauss criticises the dogmas of Christianity as sharply as he had criticised the Gospel narrative in the first one. The historical development of these has of itself effected their destruction: the history of dogma is the objective criticism of dogma. Christianity and philosophy, theism and pantheism, dualism and immanence, are irreconcilable opposites. To be able to know we must cease to believe. Dogma is the product of the unphilosophical, uncultured consciousness; belief in revelation, only for those who have not yet risen to reason. In the transformation of religious representations into philosophical Ideas nothing specifically representative is left; the form of representation must be actually overcome. The Christian contraposition of the present world and that which is beyond is explained by the fact that the sensuo-rational spirit of man, so long as it does not philosophically know itself as the unity of the infinite and the finite, but only feels itself as finite, sensuo-empirical consciousness, projects the infinite, which it has in itself, as though this were something foreign, looks on it as something beyond the world. This separation of faith is entirely unphilosophical; it is the mission of the philosopher to reduce all that is beyond the world to the present. Thus for him immortality is not something to come, but the spirit's own power to rise above the finite to the Idea. And like future existence, so the transcendent God also disappears. The absolute is the universal unity of the world, which posits and sublates the individual as its modes. God is the being in all existence, the life in all that lives, the thought in all that think: he does not stand as an individual person beside and above other persons, but is the infinite which personifies itself and attains to consciousness in human spirits, and this from eternity; before there was a humanity of earth there were spirits on other stars, in whom God reflected himself.
Three decades later Strauss again created a sensation by his confession of materialism and atheism, The Old Faith and the New, 1872 (since the second edition, "With a Postscript as Preface"), in which he continues the conflict against religious dualism. The question "Are we"--the cultured men of the day--"still Christians?" is answered in the negative. Christianity is a cult of poverty, despising the world, and antagonistic to labor and culture; but we have learned to esteem science and art, riches and acquisition, as the chief levers of culture and of human progress. Christianity dualistically tears apart body and soul, time and eternity, the world and God; we need no Creator, for the life-process has neither beginning nor end. The world is framed for the highest reason, it is true, but it has not been framed by a highest reason. Our highest Idea is the All, which is conformed to law, and instinct with life and reason, and our feeling toward the universe--the consciousness of dependence on its laws--exercises no less of ethical influence, is no less full of reverence, and no less exposed to injury from an irreverent pessimism, than the feeling of the devout of the old type toward their God. Hence the answer to the second question "Have we still a religion?" maybe couched in the affirmative. The new faith does not need a cultus and a Church. Since the dry services of the free congregations offer nothing for the fancy and the spirit, the edification of the heart must be accomplished in other ways--by participation in the interests of humanity, in the national life, and, not last, by aesthetic enjoyment. Thus in his last work, which in two appendices reaches a discussion of the great German poets and musicians, the old man returns to a thought to which he had given earlier expression, that the religious cultus should be replaced by the cultus of genius.
As Strauss went over from Hegelianism to pantheism, so Ludwig Feuerbach (1804-72), a son of the great jurist, Anselm Feuerbach, after he had for a short time moved in the same direction, took the opposite, the individualistic course, only, like Strauss, to end at last in materialism. "My first thought," as he himself describes the course of his development, "was God; my second, reason; my third and last, man." As theology has been overcome by Hegel's philosophy of reason, so this in turn must give place to the philosophy of man. "The new philosophy makes man, including nature as his basis, the highest and sole subject of philosophy, and, consequently, anthropology the universal science." Only that which is immediately self-evident is true and divine. But only that which is sensible is evident (sonnenklar); it is only where sensibility begins that all doubt and conflict cease. Sensible beings alone are true, real beings; existence in space and time is alone existence; truth, reality, and sensibility are identical. While the old philosophy took for its starting point the principle, "I am an abstract, a merely thinking being; the body does not belong to my essence," the new philosophy, on the other hand, begins with the principle, "I am a real, a sensible being; the body in its totality is my ego, my essence itself." Feuerbach, however, uses the concept of sensibility in so wide and vague a sense that, supported--or deceived--by the ambiguity of the word sensation, he includes under it even the most elevated and sacred feelings. Even the objects of art are seen, heard, and felt; even the souls of other men are sensed. In the sensations the deepest and highest truths are concealed. Not only the external, but the internal also, not only flesh, but spirit, not only the thing, but the ego, not only the finite, the phenomenal, but also the true divine essence is an object of the senses. Sensation proves the existence of objects outside our head--there is no other proof of being than love, than sensation in general. Everything is perceivable by the senses, if not directly, yet indirectly, if not with the vulgar, untrained senses, yet with the "cultivated senses," if not with the eye of the anatomist or chemist, yet with that of the philosopher. All our ideas spring from the senses, but their production requires communication and converse between man and man. The higher concepts cannot be derived from the individual Ego without a sensuously given Thou; the highest object of sense is man; man does not reach concepts and reason in general by himself, but only as one of two. The nature of man is contained in community alone; only in life with others and for others does he attain his destiny and happiness. The conscience is the ego putting itself in the place of another who has been injured. Man with man, the unity of I and Thou, is God, and God is love.

To the philosophy of religion Feuerbach assigns the task of giving a psychological explanation of the genesis of religion, instead of showing reason in religion. In bidding us believe in miracles dogma is a prohibition to think. Hence the philosopher is not to justify it, but to uncover the illusion to which it owes its origin. Speculative theology is an intoxicated philosophy; it is time to become sober, and to recognize that philosophy and religion are diametrically opposed to each other, that they are related to each other as health to disease, as thought to phantasy. Religion arises from the fact that man objectifies his own true essence, and opposes it to himself as a personal being, without coming to a consciousness of this divestment of self, of the identity of the divine and human nature. Hence the Hegelian principles, that the absolute is self-consciousness, that in man God knows himself, must be reversed: self-consciousness is the absolute; in his God man knows himself only. The Godhead is our own universal nature, freed from its individual limitations, intuited and worshiped as another, independent being, distinct from us. God is self objectified, the inner nature of man expressed; man is the beginning, the middle, and the end of religion. All theology is anthropology, for all religion is a self-deification of man. In religion man makes a division in his own nature, posits himself as double, first as limited (as a human individual), then as unlimited, raised to infinity (as God); and this deified self he worships in order to obtain from it the satisfaction of his needs, which the course of the world leaves unmet. Thus religion grows out of egoism: its basis is the difference between our will and our power; its aim, to set us free from the dependence which we feel before nature. (Like culture, religion seeks to make nature an intelligible and compliant being, only that in this it makes use of the supernatural instruments faith, prayer, and magic; it is only gradually that men learn to attack the evils by natural means.) That which man himself is not, but wishes to be, that he represents to himself in his gods as existing; they are the wishes of man's heart transformed into real beings, his longing after happiness satisfied by the fancy. The same holds true of all dogmas: as God is the affirmation of our wishes, so the world beyond is the present embellished and idealized by the fancy. Instead of "God is merciful, is love, is omnipotent, he performs miracles and hears prayers," the statement must be reversed: mercy, love, omnipotence, to perform miracles, and to hear prayers, is divine. In the sacraments of baptism and the Lord's supper Feuerbach sees the truth that water and food are indispensable and divine. As Feuerbach, following out this naturalistic tendency, reached the extreme of materialism, the influence of his philosophy--whose different phases there is no occasion to trace out in detail--had already passed its culmination. From his later writings little more has found its way into public notice than the pun, that man is (ist) what he eats (isst).
The remaining members of the Hegelian left may be treated more briefly. Bruno Bauer (died in 1882; his principal work is the Critique of the Synoptics, in three volumes, 1841-42, which had been preceded, in 1840, by a Critique of the Evangelical History of John) at first belonged on the right of the school, but soon went over to the extreme left. He explains the Gospel narratives as creations with a purpose (Tendenzdichtungen), as intentional, but not deceitful, inventions, from which, despite their unreality, history may well be learned, inasmuch as they reflect the spirit of the time in which they were constructed. His own publications and those of his brother Edgar are much more radical after the year 1844. In these the brothers advocate the standpoint of "pure or absolute criticism," which extends itself to all things and events for or against which sides are taken from any quarter, and calmly watches how everything destroys itself. As soon as anything is admitted, it is no longer true. Nothing is absolutely valid, all is vain; it is only the criticising, all-destroying ego, free from all ethical ties, that possesses truth.
One further step was possible beyond Feuerbach and Bruno Bauer, that from the community to the particular, selfish individual, from the criticising, therefore thinking, ego, to the ego of sensuous enjoyment. This step was taken in that curious book The Individual and his Property, which Kaspar Schmidt, who died in 1856 at Berlin, published in 1845 (2d ed., 1882), under the pseudonym of Max Stirner. The Individual of whom the title speaks is the egoist. For me nothing is higher than myself; I use men and use up the world for my own pleasure. I seek to be and have all that I can be and have; I have a right to all that is within my power. Morality is a delusion, justice, like all Ideas, a phantom. Those who believe in ideals, and worship such generalities as self-consciousness, man, society, are still deep in the mire of prejudice and superstition, and have banished the old orthodox phantom of the Deity only to replace it by a new one. Nothing whatever is to be respected.
Among the opponents of the Hegelian philosophy the members of the "theistic school," who have above been designated as semi-Hegelians, approximate it most closely. These endeavor, in part retaining the dialectic method, to blend the immanence of the absolute, which philosophy cannot give up and concerning which Hegel had erred only by way of over-emphasis, with the transcendence of God demanded by Christian consciousness, to establish a theism which shall contain pantheism as a moment in itself. God is present in all creatures, yet distinct from them; he is intramundane as well as extramundane; he is self-conscious personality, free creative spirit, is this from all eternity, and does not first become such through the world-development. He does not need the world for his perfection, but out of his goodness creates it. Philosophy must begin with the living Godhead instead of beginning, like Hegel's Logic, with the empty concept of being. For the categories--as Schelling had already objected--express necessary forms or general laws only, to which all reality must conform, but which are never capable of generating reality; the content which appears in them and which obeys them, can only be created by a Deity, and only empirically cognized. This is the standpoint of Christian Hermann Weisse in Leipsic (1801-66), Karl Philipp Fischer in Erlangen (1807-85), Immanuel Hermann Fichte (1797-1879; 1842-65 professor in Tübingen), and the follower of Schleiermacher, Julius Braniss in Breslau (1792-1873). The following hold similar views, influenced, like Weisse and K. Ph. Fischer, by Schelling: Jacob Sengler of Freiburg (1799-1878; The Idea of God, 1845 seq.), Leopold Schmid of Giessen (1808-69; cf. p. 516, note), Johannes Huber (died 1879), Moritz Carrière (born 1817), both in Munich, K. Steffensen of Basle (1816-88; Collected Essays, 1890), and Karl Heyder in Erlangen (1812-86; The Doctrine of Ideas, vol. i. 1874). Chalybaeus at Kiel (died 1862), and Friedrich Harms at Berlin (died 1880; Metaphysics, posthumously edited by H. Wiese, 1885), who, like Fortlage and I.H. Fichte, start from the system of the elder Fichte, should also be mentioned as sympathizing with the opinions of those who have been named.
The same may be said, further, of Hermann Ulrici of Halle (1806-84), for many years the editor of the Zeitschrift für Philosophie und philosophische Kritik, founded in 1837 by the younger Fichte and now edited by the author of this History, which, as the organ of the theistic school, opposed, first, the pantheism of the Young Hegelians, and then the revived materialism so loudly proclaimed after the middle of the century. This Zeitschrift of Fichte and Ulrici, following the altered circumstances of the time, has experienced a change of aim, so that it now seeks to serve idealistic efforts of every shade; while the Philosophische Monatshefte (founded by Bergmann in 1868, edited subsequently by Schaarschmidt, and now) edited by P. Natorp of Marburg, favors neo-Kantianism, and the Vierteljahrsschrift für wissenschaftliche Philosophie (begun in 1877, and) edited by R. Avenarius of Zurich, especially cultivates those parts of philosophy which are open to exact treatment.
; Faith and Knowledge, 1858; God and Nature, 1861, 2d ed., 1866; God and Man, in two volumes, Body and Soul, 1866, 2d ed., 1874, and Natural Law, 1872; various treatises on Logic--in which consciousness is based on the distinguishing activity, and the categories conceived as functional modes of this--on Spiritualism, etc.]
The appearance of materialism was the consequence of the flagging of the philosophic spirit, on the one hand, and, on the other, of the dissatisfaction of the representatives of natural science with the constructions of the Schelling-Hegelian school. If the German naturalist is especially exposed to the danger of judging all reality from the section of it with which he is familiar, from the world of material substances and mechanical motions, the reason lies in the fact that he does not find it easy, like the Englishman for example, to let the scientific and the philosophico-religious views of the world go on side by side as two entirely heterogeneous modes of looking at things. The metaphysical impulse to generalization and unification spurs him on to break down the boundary between the two spheres, and, since the physical view of things has become part of his flesh and blood, psychical phenomena are for him nothing but brain-vibrations, and the freedom of the will and all religious ideas, nothing but illusions. The materialistic controversy broke out most actively at the convention of naturalists at Göttingen in 1854, when Rudolph Wagner in his address "On the Creation of Man and the Substance of the Soul" declared, in opposition to Karl Vogt, that there is no physiological reason for denying the descent of man from one pair and an immaterial immortal soul. Vogt's answer was entitled "Collier Faith and Science." Among others Schaller (Body and Soul, 1855), J.B. Meyer in a treatise with the same title, 1856, and the Jena physicist, Karl Snell, took part in the controversy by way of criticism and mediation. A much finer nature than the famous leaders of materialism--Moleschott (The Circle of Life*, 1852, in answer to Liebig's *Chemical Letters), and Louis Büchner, with whose Force and Matter (1855, 16th ed., 1888; English translation by Collingwood, 4th ed., 1884) the gymnasiast of to-day still satisfies his freethinking needs--is H. Czolbe (1819-73; New Exposition of Sensationalism*, 1855; *The Limits and Origin of Human Knowledge, 1865), who, on ethical grounds, demands the exclusion of everything suprasensible and contentment with the given world of phenomena, but holds that, besides matter and motion, eternal, purposive forms and original sensations in a world-soul are necessary to explain organic and psychical phenomena.
%2. New Systems: Trendelenburg, Fechner, Lotze, and Hartmann%.
The speculative impulse, especially in the soul of the German people, is ineradicable. It has neither allowed itself to be discouraged by the collapse of the Hegelian edifice, nor to be led astray by the clamor of the apostles of empiricism, nor to be intimidated by the papal proclamation of the infallibility of Thomas Aquinas. Manifold attempts have been made at a new conception of the world, and with varying success. Of the earlier theories only two have been able to gather a circle of adherents--the dualistic theism of Günther (1783-1863), and the organic view of the world of Trendelenburg (1802-72).
Anton Günther (engaged in authorship from 1827; Collected Writings, 1881; Anti-Savarese, edited with an appendix by P. Knoodt), who in 1857 was compelled to retract his views, invokes the spirit of Descartes in opposition to the Hegelian pantheism. In agreement with Descartes, Günther starts from self-consciousness (in the ego being and thought are identical), and brings not only the Creator and the created world, but also nature (to which the soul is to be regarded as belonging) and spirit into a relation of exclusive opposition, yet holds that in man nature (body and soul) and spirit are united, and that they interact without prejudice to their qualitative difference. J.H. Pabst (died in 1838 in Vienna), Theodor Weber of Breslau, Knoodt of Bonn (died 1889), V. Knauer of Vienna and others are Güntherians.
Adolf Trendelenburg of Berlin, the acute critic of Hegel and Herbart, in his own thinking goes back to the philosophy of the past, especially to that of Aristotle. Motion and purpose are for him fundamental facts, which are common to both being and thinking, which mediate between the two, and make the agreement of knowledge and reality possible. The ethical is a higher stage of the organic. Space, time, and the categories are forms of thought as well as of being; the logical form must not be separated from the content, nor the concept from intuition. We must not fail to mention that Trendelenburg introduced a peculiar and fruitful method of treating the history of philosophy, viz., the historical investigation of particular concepts, in which Teichmüller of Dorpat (1832-88; Studies in the History of Concepts*, 1874; *New Studies in the History of Concepts, 1876-79; The Immortality of the Soul, 2d ed., 1879; The Nature of Love, 1880; Literary Quarrels in the Fourth Century before Christ, 1881 and 1884), and Eucken of Jena (cf. pp. 17 and 623) have followed his example. Kym in Zurich (born 1822; Metaphysical Investigations, 1875; The Problem of Evil, 1878) is a pupil of Trendelenburg.
Of more recent systematic attempts the following appear worthy of mention: Von Kirchmann (1802-84; from 1868 editor of the Philosophische Bibliothek*), The Philosophy of Knowledge, 1865; Aesthetics, 1868; On the Principles of Realism, 1875; *Catechism of Philosophy 2d ed., 1881; E. Dühring (born 1833), Natural Dialectic, 1865; The Value of Life, 1865, 3d ed, 1881; Critical History of the Principles of Mechanics, 1873, 2d ed., 1877; Course of Philosophy, 1875 (cf. on Dühring, Helene Druskowitz, 1889); J. Baumann of Göttingen (born 1837), Philosophy as Orientation concerning the World*, 1872; *Handbook of Ethics, 1879; Elements of Philosophy, 1891; L. Noiré, The Monistic Idea, 1875, and many other works; Frohschammer of Munich (born 1821), The Phantasy as the Fundamental Principle of the World-process*, 1877; On the Genesis of Humanity, and its Spiritual Development in Religion, Morality and Language, 1883; *On the Organization and Culture of Human Society, 1885.
In the first rank of the thinkers who have made their appearance since Hegel and Herbart stand Fechner and Lotze, both masters in the use of exact methods, yet at the same time with their whole souls devoted to the highest questions, and superior to their contemporaries in breadth of view as in the importance and range of their leading ideas--Fechner a dreamer and sober investigator by turns, Lotze with gentle hand reconciling the antitheses in life and science.
Gustav Theodor Fechner (1801-87; professor at Leipsic) opposes the abstract separation of God and the world, which has found a place in natural inquiry and in theology alike, and brings the two into the same relation of correspondence and reciprocal reference as the soul and the body. The spirit gives cohesion to the manifold of material parts, and needs them as a basis and material for its unifying activity. As our ego connects the manifold of our activities and states in the unity of consciousness, so the divine spirit is the supreme unity of consciousness for all being and becoming. In the spirit of God everything is as in ours, only expanded and enhanced. Our sensations and feelings, our thoughts and resolutions are His also, only that He, whose body all nature is, and to whom not only that which takes place in spirits is open, but also that which goes on between them, perceives more, feels deeper, thinks higher, and wills better things than we. According to the analogy of the human organism, both the heavenly bodies and plants are to be conceived as beings endowed with souls, although they lack nerves, a brain, and voluntary motion. How could the earth bring forth living beings, if it were itself dead? Shall not the flower itself rejoice in the color and fragrance which it produces, and with which it refreshes us? Though its psychical life may not exceed that of an infant, its sensations, at all events, since they do not form the basis of a higher activity, are superior in force and richness to those of the animal. Thus the human soul stands intermediate in the scale of psychical life: beneath and about us are the souls of plants and animals, above us the spirits of the earth and stars, which, sharing in and encompassing the deeds and destinies of their inhabitants, are in their turn embraced by the consciousness of the universal spirit. The omnipresence of the divine spirit affords at the same time the means of escaping from the desolate "night view" of modern science, which looks upon the world outside the perceiving individual as dark and silent. No, light and sound are not merely subjective phenomena within us, but extend around us with objective reality--as sensations of the divine spirit, to which everything that vibrates resounds and shines.
The door of the world beyond also opens to the key of analogy. Similar laws unite the here with the hereafter. As intuition prepares the way for memory, and lives on in it, so the life of earth merges in the future life, and continues active in it, elevated to a higher plane. Fechner treats the problem of evil in a way peculiar to himself. We must not consider the fact of evil apart from the effort to remove it. It is the spur to all activity--without evil, no labor and no progress.
Fechner's "psycho-physics," a science which was founded by him in continuation of the investigations of Bernoulli, Euler, and especially of E.H. Weber, wears an entirely different aspect from that of his metaphysics (the "day view," moreover does not claim to be knowledge, but belief--though a belief which is historically, practically, and theoretically well-grounded). This aims to be an exact science of the relations between body and mind, and to reach indirectly what Herbart failed to reach by direct methods, that is, a measurement of psychical magnitudes, using in this attempt the least observable differences in sensations as the unit of measure. Weber's law of the dependence of the intensity of the sensation on the strength of the stimulus--the increase in the intensity of the sensation remains the same when the relative increase of the stimulus (or the relation of the stimuli) remains constant; so that, e.g., in the case of light, an increase from a stimulus of intensity 1 to one of intensity 100, gives just the same increase in the intensity of the sensation as an increase from a stimulus of intensity 2 (or 3) to a stimulus of 200 (or 300)--is much more generally valid than its discoverer supposed; it holds good for all the senses. In the case of the pressure sense of the skin, with an original weight of 15 grams (laid upon the hand when at rest and supported), in order to produce a sensation perceptibly greater we must add not 1 gram, but 5, and with an original weight of 30 grams, not 5, but 10. Equal additions to the weights are not enough to produce a sensation of pressure whose intensity shall render it capable of being distinguished with certainty, but the greater the original weights the larger the increments must be; while the intensities of the sensations form an arithmetical, those of the stimuli form a geometrical, series; the change in sensation is proportional to the relative change of the stimulus. Sensations of tone show the same proportion (3:4) as those of pressure; the sensibility of the muscle sense is finer (when weights are raised the proportion is 15:16), as also that of vision (the relative brightness of two lights whose difference of intensity is just perceptible is 100:101). In addition to the investigations on the threshold of difference there are others on the threshold of stimulation (the point at which a sensation becomes just perceptible), on attention, on methods of measurement, on errors, etc. Moreover, Fechner does not fail to connect his psycho-physics, the presuppositions and results of which have recently been questioned in several quarters, with his metaphysical conclusions. Both are pervaded by the fundamental view that body and spirit belong together (consequently that everything is endowed with a soul, and that nothing is without a material basis), nay, that they are the same essence, only seen from different sides. Body is the (manifold) phenomenon for others, while spirit is the (unitary) self-phenomenon, in which, however, the inner aspect is the truer one. That which appears to us as the external world of matter, is nothing but a universal consciousness which overlaps and influences our individual consciousness. This is Spinozism idealistically interpreted. In aesthetics Fechner shows himself an extreme representative of the principle of association.
The most important of the thinkers mentioned in the title of this section is Rudolph Hermann Lotze (1817-81: born at Bautzen; a student of medicine, and of philosophy under Weisse, in Leipsic; 1844-81 professor in Göttingen; died in Berlin). Like Fechner, gifted rather with a talent for the fine and the suggestive than for the large and the rigorous, with a greater reserve than the former before the mystical and peculiar, as acute, cautious, and thorough as he was full of taste and loftiness of spirit, Lotze has proved that the classic philosophers did not die out with Hegel and Herbart. His Microcosmus (3 vols., 1856-64, 4th ed., 1884 seq; English translation by Hamilton and Jones, 3d ed., 1888), which is more than an anthropology, as it is modestly entitled, and History of Aesthetics in Germany, 1868, which also gives more than the title betrays, enjoy a deserved popularity. These works were preceded by the Medical Psychology, 1852, and a polemic treatise against I.H. Fichte, 1857, as well as by a Pathology and a Physiology, and followed by the System of Philosophy, which remained incomplete (part i. Logic, 1874, 2d ed., 1881, English translation edited by Bosanquet, 2d ed., 1888; part ii. Metaphysics, 1879, English translation edited by Bosanquet, 2d ed., 1887). Lotze's Minor Treatises have been published by Peipers in three volumes (1885-91); and Rehnisch has edited eight sets of dictata from his lectures, 1871-84. Since these "Outlines," all of which we now have in new editions, make a convenient introduction to the Lotzean system, and are, or should be, in the possession of all, a brief survey may here suffice.
On Lotze cf. the obituaries by J. Baumann (Philosophische Monatshefte, vol. xvii.), H. Sommer (Im Neuen Reich), A. Krohn (Zeitschrift für Philosophie, vol. lxxxi. pp. 56-93), R. Falckenberg (Augsburg Allgemeine Zeitung, 1881, No. 233), and Rehnisch (National Zeitung and the Revue Philosophique, vol. xii.). The last of these was reprinted in the appendix to the Grundzüge der Aesthetik, 1884, which contains, further, a chronological table of Lotze's works, essays, and critiques, as well as of his lectures. Hugo Sommer has zealously devoted himself to the popularization of the Lotzean system. Cf., further, Fritz Koegel, Lotzes Aesthetik, Göttingen, 1886, and the article by Koppelmann referred to above, p. 330.]
The subject of metaphysics is reality. Things which are, events which happen, relations which exist, representative contents and truths which are valid, are real. Events happening and relations existing presuppose existing things as the subjects in and between which they happen and exist. The being of things is neither their being perceived (for when we say that a thing is we mean that it continues to be, even when we do not perceive it), nor a pure, unrelated position, its position in general, but to be is to stand in relations*. Further, the *what or essence of the things which enter into these relations cannot be conceived as passive quality, but only abstractly, as a rule or a law which determines the connection and succession of a series of qualities. The nature of water, for example, is the unintuitable somewhat which contains the ground of the change of ice, first into the liquid condition, and then into steam, when the temperature increases, and conversely, of the possibility of changing steam back into water and ice under opposite conditions. And when we speak of an unchangeable identity of the thing with itself, as a result of which it remains the same essence amid the change of its phenomena, we mean only the consistency with which it keeps within the closed series of forms a1, a2, a3, without ever going over into the series b1, b2. The relations, however, in which things stand, cannot pass to and fro between things like threads or little spirits, but are states in things themselves, and the change of the former always implies a change in these inner states. To stand in relations means to exchange actions. In order to experience such effects from others and to exercise them upon others, things must neither be wholly incomparable (as red, hard, sweet) and mutually indifferent, nor yet absolutely independent; if the independence of individual beings were complete the process of action would be entirely inconceivable. The difficulty in the concept of causality--how does being a come to produce in itself a different state a because another being b enters into the state [Greek: b]?--is removed only when we look on the things as modes, states, parts of a single comprehensive being, of an infinite, unconditioned substance, in so far as there is then only an action of the absolute on itself. Nevertheless the assumption that, in virtue of the unity and consistency of the absolute or of its impulse to self-preservation, state [Greek: b] in being b follows state [Greek: a] in being a as an accommodation or compensation follows a disturbance, is not a full explanation of the process of action, does not remove the difficulty as to how one state can give rise to another. Metaphysics is, in general, unable to show how reality is made, but only to remove certain contradictions which stand in the way of the conceivability of these notions. The so far empty concept of an absolute looks to the philosophy of religion for its content; the conception of the Godhead as infinite personality (it is a person in a far higher sense than we) is first produced when we add to the ontological postulate of a comprehensive substance the ethical postulate of a supreme good or a universal world-Idea.
By "thing" we understand the permanent unit-subject of changing states. But the fact of consciousness furnishes the only guaranty that the different states a, [Greek: b], y, are in reality states of one being, and not so many different things alternating with one another. Only a conscious being, which itself effects the distinction between itself and the states occurring in it, and in memory and recollection feels and knows itself as their identical subject, is actually a subject which has states. Hence, if things are to be real, we must attribute to them a nature in essence related to that of our soul. Reality is existence for self. All beings are spiritual, and only spiritual beings possess true reality. Thus Lotze combines the monadology of Leibnitz with the pantheism of Spinoza, just as he understands how to reconcile the mechanical view of natural science (which is valid also for the explanation of organic life) with the teleology and the ethical idealism of Fichte. The sole mission of the world of forms is to aid in the realization of the ideal purposes of the absolute, of the world of values.
The ideality of space, which Kant had based on insufficient grounds, is maintained by Lotze also, only that he makes things stand in "intellectual" relations, which the knowing subject translates into spatial language. The same character of subjectivity belongs not only to our sensations, but also to our ideas concerning the connection of things. Representations are results, not copies, of the external stimuli; cognition comes under the general concept of the interaction of real elements, and depends, like every effect, as much upon the nature of the being that experiences the effect as upon the nature of the one which exerts it, or rather, more upon the former than upon the latter. If, nevertheless, it claims objective reality, truth must not be interpreted as the correspondence of thought and its object (the cognitive image can never be like the thing itself), nor the mission of cognition, made to consist in copying a world already finished and closed apart from the realm of spirits, to which mental representation is added as something accessory. Light and sound are not therefore illusions because they are not true copies of the waves of ether and of air from which they spring, but they are the end which nature has sought to attain through these motions, an end, however, which it cannot attain alone, but only by acting upon spiritual subjects; the beauty and splendor of colors and tones are that which of right ought to be in the world; without the new world of representations awakened in spirits by the action of external stimuli, the world would lack its essential culmination. The purpose of things is to be known, experienced, and enjoyed by spirits. The truth of cognition consists in the fact that it opens up the meaning and destination of the world. That which ought to be is the ground of that which is; that which is exists in order to the realization of values in it; the good is the only real. It is true that we are not permitted to penetrate farther than to the general conviction that the Idea of the good is the ground and end of the world; the question, how the world has arisen from this supreme Idea as from the absolute and why just this world with its determinate forms and laws has arisen, is unanswerable. We understand the meaning of the play, but we do not see the machinery by which it is produced at work behind the stage. In ethics Lotze emphasizes with Fechner the inseparability of the good and pleasure: it is impossible to state in what the worth or goodness of a good is to consist, if it be conceived out of all relation to a spirit capable of finding enjoyment in it.
If Lotze's philosophy harmoniously combines Herbartian and Fichteo-Hegelian elements, Eduard von Hartmann (born 1842; until 1864 a soldier, now a man of letters in Berlin) aims at a synthesis of Schopenhauer and Hegel; with the pessimism of the former he unites the evolutionism of the latter, and while the one conceives the nature of the world-ground as irrational will, and the other as the logical Idea, he follows the example of Schelling in his later days by making will and representation equally legitimate attributes of his absolute, the Unconscious. His principal theoretical work, The Philosophy of the Unconscious, 1869 (10th ed., 1891; English translation by Coupland, 1884), was followed in 1879 by his chief ethical one, The Moral Consciousness (2d ed., 1886, in the Selected Works); the two works on the philosophy of religion, The Religious Consciousness of Humanity in the Stages of its Development*, 1881, and The Religion of Spirit, 1882, together form the third chief work (The Self-Disintegration of Christianity and the Religion of the Future, 1874, and *The Crisis of Christianity in Modern Theology, 1880, are to be regarded as forerunners of this); the fourth is the Aesthetics (part i. German Aesthetics since Kant*, 1886; part ii. Philosophy of the Beautiful, 1887). The *Collected Studies and Essays, 1876, were preceded by two treatises on the philosophy of nature, Truth and Error in Darwinism, 1875, and The Unconscious from the Standpoint of Physiology and the Theory of Descent, published anonymously in 1872, in the latter of which, disguised as a Darwinian, he criticises his own philosophy. Of his more recent publications we may mention the Philosophical Questions of the Day, 1885; Modern Problems, 1886; and the controversial treatise Lotzes Philosophy, 1888.
In polemical relation, on the one hand, to the naïve realism of life, and, on the other, to the subjective idealism of Kant, or rather of the neo-Kantians, the logical conclusion of which would be absolute illusionism, Hartmann founds his "transcendental realism," which mediates between these two points of view (the existence and true nature of the world outside our representations is knowable, if only indirectly; the forms of knowledge, in spite of their subjective origin, have a more than subjective, a transcendental, significance) by pointing out that sense-impressions, which are accompanied by the feeling of compulsion and are different from one another, cannot be explained from the ego, but only by the action of things in themselves external to us, i.e., independent of consciousness, and themselves distinct from one another. The causality of things in themselves is the bridge which enables us to cross the gulf between the immanent world of representations and the transcendent world of being. The causality of things in themselves proves their reality, their difference at different times, their changeability and their temporal character; change, however, demands something permanent, existence, an existing, unchangeable, supra-temporal, and non-spatial substance (whether a special substance for each thing in itself or a common one for all, is left for the present undetermined). My action upon the thing in itself assures me of its causal conditionality or necessity; the various affections of the same sense, that there are many things in themselves; the peculiar form of change shown by some bodies, that these, like my body, are united with a soul. Thus it is evident that, besides the concept of cause, a series of other categories must be applied to the thing in itself, hence applied transcendentally.
The "speculative results" obtained by Hartmann on an "inductive" basis are as follows: The per se (Ansich) of the empirical world is the Unconscious. The two attributes of this absolute are the active, groundless, alogical, infinite will, and the passive, finite representation (Idea); the former is the ground of the that of the world, the latter the ground of its purposive what and how. Without the will the representation, which in itself is without energy, could not become real, and without the representation (of an end) the will, which in itself is without reason, could not become a definite willing (relative or immanent dualism of the attributes, a necessary moment in absolute monism). The empirical preponderance of pain over pleasure, which can be shown by calculation, proves that the world is evil, that its non-existence were better than its existence; the purposiveness everywhere perceptible in nature and the progress of history toward a final goal (it is true, a negative one) proves, nevertheless, that it is the best world that was possible (reconciliation of eudemonistic pessimism with evolutionistic optimism). The creation of the world begins when the blind will to live groundlessly and fortuitously passes over from essence to phenomenon, from potency to act, from supra-existence to existence, and, in irrational striving after existence, draws to itself the only content which is capable of realization, the logical Idea. This latter seeks to make good the error committed by the will by bringing consciousness into the field as a combatant against the insatiable, ever yearning, never satisfied will, which one day will force the will back into latency, into the (antemundane) blessed state of not-willing. The goal of the world-development is deliverance from the misery of existence, the peace of non-existence, the return from the will and representation, become spatial and temporal, to the original, harmonious equilibrium of the two functions, which has been disturbed by the origin of the world or to the antemundane identity of the absolute. The task of the logical element is to teach consciousness more and more to penetrate the illusion of the will--in its three stages of childlike (Greek) expectation of happiness to be attained here, youthful (Christian) expectation of happiness to be attained hereafter, and adult expectation of happiness to be attained in the future of the world-development--and, finally, to teach it to know, in senile longing after rest, that only the doing away with this miserable willing, and, consequently, with earthly existence (through the resolve of the majority of mankind) can give the sole attainable blessedness, freedom from pain. The world-process is the incarnation, the suffering, and the redemption of the absolute; the moral task of man is not personal renunciation and cowardly retirement, but to make the purposes of the Unconscious his own, with complete resignation to life and its sufferings to labor energetically in the world-process, and, by the vigorous promotion of consciousness, to hasten the fulfillment of the redemptive purpose; the condition of morality is insight into the fruitlessness of all striving after pleasure and into the essential unity of all individual beings with one another and with the universal spirit, which exists in the individuals, but at the same time subsists above them. "To know one's self as of divine nature, this does away with all divergence between selfwill and universal will, with all estrangement between man and God, with all undivine, that is, merely natural, conduct."
Religion, which, in common with philosophy, has for its basis the metaphysical need for, or the mystical feeling of, the unity of the human individual and the world-ground, needs transformation, since in its traditional forms it is opposed to modern culture, and the merging of religion (as a need of the heart) in metaphysics is impossible. The religion of the future, for which the way has already been prepared by the speculative Protestantism of the present, is concrete monism (the divine unity is transcendent as well as immanent in the plurality of the beings of earth, every moral man a God-man), which includes in itself the abstract monism (pantheism) of the Indian religions and the Judeo-Christian (mono-) theism as subordinate moments. (The original henotheism and its decline into polytheism, demonism, and fetichism was followed by--Egyptian and Persian, as well as Greek, Roman, and German--naturalism, and then by supernaturalism in its monistic and its theistic form. The chief defect of the Christian religion is the transcendental-eudemonistic heteronomy of its ethics.) The Religion of Spirit divides into three parts. The psychology of religion considers the religious function in its subjective aspect, faith as a combined act of representation, feeling, and will, in which one of these three elements may predominate--though feeling forms the inmost kernel of the theoretical and practical activities as well--and, as the objective correlate of faith, grace (revealing, redeeming, and sanctifying), which elevates man above peripheral and phenomenal dependence on the world, and frees him from it, through his becoming conscious of his central and metaphysical dependence upon God. The metaphysics of religion (in theological, anthropological, and cosmological sections) proves by induction from the facts of religion the existence, omnipotence, spirituality, omniscience, righteousness, and holiness of the All-one, which coincides with the moral order of the world. Further, it proves the need and the capacity of man for redemption from guilt and evil--here three spheres of the individual will are distinguished, one beneath God, one contrary to God, and one conformable to God, or a natural, an evil, and a moral sphere--and, preserving alike the absoluteness of God and the reality of the world, shows that it is not so much man as God himself, who, as the bearer of all the suffering of the world, is the subject of redemption. The ethics of religion discusses the subjective and objective processes of redemption, namely, repentance and amendment on the part of the individual and the ecclesiastical cultus of the future, which is to despise symbols and art.
It is to Hartmann's credit, though the fact has not been sufficiently appreciated by professional thinkers, that in a time averse to speculation he has devoted his energies to the highest problems of metaphysics, and in their elaboration has approached his task with scientific earnestness and a comprehensive and thorough consideration of previous results. Thus the critique of ethical standpoints in the historical part of the Phenomenology of the Moral Consciousness, especially, contains much that is worthy of consideration; and his fundamental metaphysical idea, that the absolute is to be conceived as the unity of will and reason, also deserves in general a more lively assent than has been accorded to it, while his rejection of an infinite consciousness has justly met with contradiction. It has been impossible here to go into his discussions in the philosophy of nature--they cannot be described in brief--on matter (atomic forces), on the mechanical and teleological views of life and its development, on instinct, on sexual love, etc., which he very skillfully uses in support of his metaphysical principle.
%3. From the Revival of the Kantian Philosophy to the Present Time.%
%(a) Neo-Kantianism, Positivism, and Kindred Phenomena.%--The Kantian philosophy has created two epochs: one at the time of its appearance, and a second two generations after the death of its author. The new Kantian movement, which is one of the most prominent characteristics of the philosophy of the present time, took its beginning a quarter of a century ago. It is true that even before 1865 individual thinkers like Ernst Reinhold of Jena (died 1855), the admirer of Fries, J.B. Meyer of Bonn, K.A. von Reichlin-Meldegg, and others had sought a point of departure for their views in Kant; that K. Fischer's work on Kant (1860) had given a lively impulse to the renewed study of the critical philosophy; nay, that the cry "Back to Kant" had been expressly raised by Fortlage (as early as 1832 in his treatise The Gaps in the Hegelian System), and by Zeller (p. 589). But the movement first became general after F.A. Lange in his History of Materialism had energetically advocated the Kantian doctrine according to his special conception of it, after Helmholtz (born 1821) had called attention to the agreement of the results of physiology with those of the Critique of Reason, and at the same time Liebmann's youthful work, Kant and the Epigones, in which every chapter ended with the inexorable refrain, "therefore we must go back to Kant," had given the strongest expression to the longing of the time.
Otto Liebmann (cf. also the chapter on "The Metamorphoses of the A Priori" in his Analysis of Reality) sees the fundamental truth of criticism in the irrefutable proof that, space, time, and the categories are functions of the intellect, and that subject and object are necessary correlates, inseparable factors of the empirical world, and finds Kant's fundamental error, which the Epigones have not corrected, but made still worse, in the non-concept of the thing in itself, which must be expelled from the Kantian philosophy as a remnant of dogmatism, as a drop of alien blood, and as an illegitimate invader which has debased it.
According to Friedrich Albert Lange (1828-75; during the last years of his life professor at Marburg), materialism, which is unfruitful and untenable as a principle, a system, and a view of the world, but useful and indispensable as a method and a maxim of investigation, must be supplemented by formal idealism, which, rejecting all science from mere reason limits knowledge to the sensuous, to that which can be experienced, yet at the same time conceives the formal element in the sense world as the product of the organization of man, and hence makes objects conform to our representations. Above the sensuous world of experience and of mechanical becoming, however, the speculative impulse to construction, rounding off the fragmentary truth of the sciences into a unified picture of the whole truth, rears the ideal world of that which ought to be. Notwithstanding their indefeasible certitude, the Ideas possess no scientific truth, though they have a moral value which makes them more than mere fabrics of the brain: man is framed not merely for the knowledge of truth, but also for the realization of values. But since the significance of the Ideas is only practical, and since determinations of value are not grounds of explanation, science and metaphysics or "concept poetry" (Begriffsdichtung) must be kept strictly separate.
Friedrich Paulsen of Berlin (born in 1846; cf. pp. 330, 332, note) sees in the Kantian philosophy the foundation for the philosophy of the future. A profounder Wolff (the self-dominion of the reason), a Prussian Hume (the categories of the understanding are not world-categories; rejection of anthropomorphic metaphysics), and a German Rousseau (the primacy of the will, consideration of the demands of the heart; the good will alone, not deeds nor culture, constitutes the worth of man; freedom, the rights of man) in one person, Kant has withdrawn from scientific discussion the question concerning the dependence of reality on values or the good, which is theoretically insoluble but practically to be answered in the affirmative, and given it over to faith. Kant is in so far a positivist that he limits the mission of knowledge to the reduction of the temporo-spatial relations of phenomena to rules, and declares the teleological power of values to be undemonstrable. But science is able to prove this much, that the belief in a suprasensible world, in the indestructibility of that which alone has worth, and in the freedom of the intelligible character, which the will demands, is not scientifically impossible. Since, according to formal rationalism, the whole order of nature is a creation of the understanding, and hence atomism and mechanism are only forms of representation, valid, no doubt, for our peripheral point of view, but not absolutely valid, since, further, the empirical view of the world apart from the Idea of the divine unity of the world (which, it is true, is incapable of theoretical realization) would lack completion, the immediate conviction of the heart in regard to the power of the good is in no danger of attack from the side of science, although this can do no further service for faith than to remove the obstacles which oppose it. The will, not the intellect, determines the view of the world; but this is only a belief, and in the world of representation, the intelligible world, with which the will brings us into relation, can come before us only in the form of symbols.--While Albrecht Krause (The Laws of the Human Heart, a Formal Logic of Pure Feeling*, 1876) and A. Classen (Physiology of the Sense of Sight, 1877) are strict followers of Kant, J. Volkelt (*Analysis of the Fundamental Principles of Kant's Theory of Knowledge, 1879) has traced the often deplored inconsistencies and contradictions in Kant down to their roots, and has shown that in Kant's thinking, which has hitherto been conceived as too simple and transparent, but which, in fact, is extremely complicated and struggling in the dark, a number of entirely heterogeneous principles of thought (skeptical, subjectivistic, metaphysico-work, rationalistic, a priori, and practical motives) are at which, conflicting with and crippling one another, make the attainment of harmonious results impossible. Benno Erdmann (p. 330) and Hans Vaihinger (pp. 323 note, 331) have given Kant's principal works careful philological interpretation.
Among the various differences of opinion which exist within the neo-Kantian ranks, the most important relates to the question, whether the individual ego or a transcendental consciousness is to be looked upon as the executor of the a priori functions. In agreement with Schopenhauer and with Lotze, who makes the subjectivity of space, time, and the pure concepts parallel with that of the sense qualities, Lange teaches that the human individual is so organized that he must apprehend that which is sensuously given under these forms. Others, on the contrary, urge that the individual soul with its organization is itself a phenomenon, and consequently cannot be the bearer of that which precedes phenomena--space, time, and the categories as "conditions" of experience are functions of a pure consciousness to be presupposed. The antithesis of subject and object, the soul and the world, first arises in the sphere of phenomena. The empirical subject, like the world of objects, is itself a product of the a priori forms, hence not that which produces them. To the transcendental group belong Hermann Cohen in Marburg, A. Stadler, Natorp, Lasswitz (p.17), E. König (p. 17), Koppelmann (p. 330), Staudinger (p. 331). Fritz Schultze of Dresden is also to be counted among the neo-Kantians (Philosophy of Natural Science, 1882; Kant and Darwin, 1875; The Fundamental Thoughts of Materialism, 1881; The Fundamental Thoughts of Spiritualism, 1883; Comparative Psychology, i. 1, 1892).
The German positivists:--E. Laas of Strasburg (1837-85), A. Riehl of Freiburg in Baden (born 1844), and R. Avenarius of Zurich (born 1843)--develop their sensationalistic theory of knowledge in critical connection with Kant. Ernst Laas defines positivism (founded by Protagoras, advocated in modern times by Hume and J.S. Mill, and hostile to Platonic idealism) as that philosophy which recognizes no other foundations than positive facts (i.e., perceptions), and requires every opinion to exhibit the experiences on which it rests. Its basis is constituted by three articles of belief: (1) The correlative facts, subject and object, exist and arise only in connection (objects are directly known only as the contents of a consciousness, cui objecta sunt, subjects only as centers of relation, as the scene or foundation of a representative content, cui subjecta sunt: outside my thoughts body does not exist as body, nor I myself as soul). (2) The variability of the objects of perception. (3) Sensationalism--all specific differences in consciousness must be conceived as differences in degree, all higher mental processes and states, including thought, as the perceptions and experiences, transformed according to law, of beings which feel, have wants, possess memory, and are capable of spontaneous motion. The subject coincides with its feeling of pleasure and pain, from which sensation is distinguished by its objective content. The illusions of metaphysics are scientifically untenable and practically unnecessary. Various yearnings, wants, presentiments, hopes, and fancies, it is true, lead beyond the sphere of that which can be checked by sense and experience, but for none of their positions can any sufficient proof be adduced. As physics has discarded transcendent causes and learned how to get along with immanent causes, so ethics also must endeavor to establish the worth of moral good without excursions into the suprasensible. The ethical obligations arise naturally from human relations, from earthly needs. The third volume of Laas's work differs from the earlier ones by conceding the rank of facts to the principles of logic as well as to perception. Aloys Riehl opposes the theory of knowledge (which starts from the fundamental fact of sensation) as scientific philosophy to metaphysics as unscientific, and banishes the doctrine of the practical ideals from the realm of science into the region of religion and art. Richard Avenarius defends the principle of "pure experience." Sensation, which is all that is left as objectively given after the removal of the subjective additions, constitutes the content, and motion the form of being.
With the neo-Kantians and the positivists there is associated, thirdly, a coherent group of noëtical thinkers, who, rejecting extramental elements of every kind, look on all conceivable being as merely a conscious content. This monism of consciousness is advocated by W. Schuppe of Greifswald (born 1836; Noëtical Logic, 1878), J. Rehmke, also of Greifswald (The World as Percept and Concept, 1880; "The Question of the Soul" in vol. ii. of the Zeitschrift für Psychologie, 1891), A. von Leclair (Contributions to a* *Monistic Theory of Knowledge, 1882), and R. von Schubert-Soldern (Foundations of a Theory of Knowledge, 1884; On the Transcendence of Object and Subject*, 1882; *Foundations for an Ethics, 1887). J. Bergmann in Marburg (born 1840) occupies a kindred position.
It is the same scientific spirit of the time, which in the fifties led many who were weary of the idealistic speculations over to materialism, that now secures such wide dissemination and so widespread favor for the endeavors of the neo-Kantians and the positivists or neo-Baconians, who desire to see metaphysics stricken from the list of the sciences and replaced by noëtics, and the theory of the world relegated to faith. The philosophy of the present, like the pre-Socratic philosophy and the philosophy of the early modern period, wears the badge of physics. The world is conceived from the standpoint of nature, psychical phenomena are in part neglected, in part see their inconvenient claims reduced to a minimum, while it is but rarely that we find an appreciation of their independence and co-ordinate value, not to speak of their superior position. The power which natural science has gained over philosophy dates essentially from a series of famous discoveries and theories, by which science has opened up entirely new and wide outlooks, and whose title to be considered in the formation of a general view of reality is incontestable. To mention only the most prominent, the following have all posited important and far-reaching problems for philosophy as well as for science: Johannes Müller's (Müller died 1858) theory of the specific energies of the senses, which Helmholtz made use of as an empirical confirmation of the Kantian apriorism; the law of the conservation of energy discovered by Robert Mayer (1842, 1850; Helmholtz, 1847, 1862), and, in particular, the law of the transformation of heat into motion, which invited an examination of all the forces active in the world to test their mutual convertibility; the extension of mechanism to the vital processes, favored even by Lotze; the renewed conflict between atomism and dynamism; further, the Darwinian theory (1859), which makes organic species develop from one another by natural selection in the struggle for existence (through inheritance and adaptation); finally, the meta-geometrical speculations of Gauss (1828), Riemann (On the Hypotheses which lie at the Basis of Geometry, 1854, published in 1867), Helmholtz (1868), B. Erdmann (The Axioms of Geometry, 1877). G. Cantor, and others, which look on our Euclidean space of three dimensions as a special case of the unintuitable yet thinkable analytic concept of a space of n dimensions. The circumstance that these theories are still largely hypothetical in their own field appears to have stirred up rather than moderated the zeal for carrying them over into other departments and for applying them to the world as a whole. Thus, especially, the Darwinians have undauntedly attempted to utilize the biological hypothesis of the master as a philosophical principle of the world, and to bring the mental sciences under the point of view of the mechanical theory of development, though thus far with more daring and noise than success. The finely conceived ethics of Höffding (p. 585) is an exception to the rule which is the object of this remark.

Schneider (The Animal Will, 1880; *The Human Will, 1882; The Good and III of the Human Race, 1883).]
Besides the theory of knowledge, in the elaboration of which the most eminent naturalists participate with acuteness and success, psychology and the practical disciplines also betray the influence of the scientific spirit. While sociology and ethics, following the English model, seek an empirical basis and begin to make philosophical use of statistical results (E.F. Schäffle, Frame and Life of the Social Body, new ed., 1885; A. von Oettingen, Moral Statistic in its Significance for a Social Ethics, 3d ed., 1882), psychology endeavors to attain exact results in regard to psychical life and its relation to its physical basis--besides Fechner and the Herbartians, W. Wundt and A. Horwicz should be mentioned here. Wundt and, of late, Haeckel go back to the Spinozistic parallelism of material and psychical existence, only that the latter emphasizes merely the inseparability (Nichtohneeinander) of the two sides (the cell-body and the cell-soul) with a real difference between them and a metaphysical preponderance of the material side, while the former emphasizes the essential unity of body and soul, and the higher reality of the spiritual side.
%(b) Idealistic Reaction against the Scientific Spirit.%--In opposition to the preponderance of natural science and the empirico-skeptical tendency of the philosophy of the day conditioned by it, an idealistic counter-movement is making itself increasingly felt as the years go on. Wilhelm Dilthey abandons metaphysics as a basis, it is true, but (with the assent of Gierke, Preussische Jahrbücher, vol. liii. 1884) declares against the transfer of the method of natural science to the mental sciences, which require a special foundation. In spite of his critical rejection of metaphysics, Wilhelm Windelband in Strasburg (born 1848; Preludes, 1884) is, like Dilthey, to be counted among the idealists. In opposition to the individualism of the positivists, the folk-psychologists--at their head Steinthal and Lazarus (p. 536); Gustav Glogau in Kiel (born 1844) is an adherent of the same movement--defend the power of the universal over individual spirits. The spirit of the people is not a phrase, an empty name, but a real force, not the sum of the individuals belonging to the people, but an encompassing and controlling power, which brings forth in the whole body processes (e.g., language) which could not occur in individuals as such. It is only as a member of society that anyone becomes truly man; the community is the subject of the higher life of spirit.
If folk-psychology, whose title but imperfectly expresses the comprehensive endeavor to construct a psychology of society or of the universal spirit, is, as it were, an empirical confirmation of Hegel's theory of Objective Spirit, Rudolf Eucken (born 1846), pressing on in the Fichtean manner from the secondary facts of consciousness to an original real-life, endeavors to solve the question of a universal becoming, of an all-pervasive force, of a supporting unity ("totality") in the life of spirit (neither in a purely noëtical nor a purely metaphysical, but) in a noölogical way, and demands that the fundamental science or doctrine of principles direct its attention not to cognition by itself, but to the activity of psychical life as a whole.
We have elsewhere discussed the more recent attempts to establish a metaphysic which shall be empirically well grounded and shall cautiously rise from facts. In regard to the possibility of metaphysics three parties are to be distinguished: On the left, the positivists, the neo-Kantians, and the monists of consciousness, who deny it out of hand. On the right, a series of philosophers--e.g., adherents of Hegel, Herbart, and Schopenhauer--who, without making any concessions to the modern theory of knowledge, hold fast to the possibility of a speculative metaphysics of the old type. In the center, a group of thinkers who are willing to renounce neither a solid noëtical foundation nor the attainment of metaphysical conclusions--so Eduard von Hartmann, Wundt, Eucken, Volkelt (pp. 590, 617). Otto Liebmann (born 1840; On the Analysis of Reality, 1876, 2d ed., 1880; Thoughts and Facts, Heft i. 1882) demands a sharp separation between the certain and the uncertain and an exact estimation of the degree of probability which theories possess; puts the principles of metaphysics under the rubric of logical hypothesis; and, in his Climax of the Theories, 1884, calls attention to the fact that experiential science, in addition to axioms necessarily or apodictically certain and empeiremes possessing actual or assertory certainty, needs, further, a number of "interpolation maxims," which form an attribute of our type of intellectual organization (i.e., principles, according to the standard of which we supplement the fragmentary and discrete series of single perceptions and isolated observations by the interpolation of the needed intermediate links, so that they form a connected experience). The most important of these maxims are the principles of real identity, of the continuity of existence, of causality, and of the continuity of becoming. Experience is a gift of the understanding; the premises, as a rule, latent in ordinary consciousness, on whose anticipatory application our experience is based throughout, assert something absolutely incapable of being experienced. If, in order to the production of a "pure experience," we eliminate all subjective additions of the understanding contained in experiential thought (all that cannot be present at the moment or locally at hand, in short, all that cannot be the direct object and content of actual observation), this breaks up into an unordered, unconnected aggregate of discontinuous perceptual fragments; in order that a complete and articulated condition of experience may result, these fragments (the purely factual content of observation, the incoherent matter of perception) must be supplemented and connected by very much that is not observed.
Further, a reaction against crude naturalism is observable in the practical field, though political economists (Roscher) and jurists take a more active part in it than the philosophers. Personally R. von Jhering (1818-92; Purpose in Law, 2 vols., 1877-83, 2d ed., 1884-86) stands on idealistic ground, although, rejecting the nativistic and formalistic theory, he is in principle an adherent of "realism," of the principle of interest and social utility (the moral is that Which is permanently useful to society).
Finally, similar motives underlie the growing interest in the history of philosophy. The idealistic impulse seeks the nourishment which the un-metaphysical present denies to it from the great works of the past, and hopes, by keeping alive the classical achievements of previous times, to enhance the consciousness of the urgency and irrepressibleness of the highest questions, and to awaken courage for renewed attempts at their solution. Thus the study of history enters the service of systematic philosophy.
%(c) The Special Philosophical Sciences.%--The more the courage to attack the central problems of philosophy has been paralyzed by the neo-Kantian theory of knowledge and the coming-in of the positivistic spirit, the more lively has been the work of the last decades in the special departments: the transfer of the center of gravity from metaphysics to the particular sciences is the most prominent characteristic of the philosophy of the time. Logic sees century-old convictions shattered and new foundations arising. Psychology has entered into competition with physiology in regard to the discovery of the laws of the psychical functions which depend on bodily processes, while metaphysical questions are forced into the background and there is a growing distrust of the reliability of inner observation. The philosophy of religion is favored with undiminished interest and aesthetics, after long neglect, with a renewal of attention; the philosophy of history is about to reconquer its former rights. There is, moreover, an especially lively interest in ethics; and the investigation of the history of philosophy is more widely extended than ever before. We will close our sketch with a short survey of the particular disciplines.
In the department of logic the following should be mentioned as classical achievements: the works of Christoph Sigwart of Tübingen (vol. i. 1873, 2d ed., 1889; vol. ii. 1878), of Lotze (p. 605), and of Wundt (vol. i. Erkenntnisslehre, 1880; vol. ii. Methodenlehre, 1883). Besides these, Bergmann (p. 620), Schuppe (p. 619), and Benno Erdmann (Logik, vol. i. 1892) deserve notice.
In psychology the following writers have made themselves prominent: Wilhelm Wundt at Leipsic (born 1832), Grundzüge der physiologischen Psychologie*, 1874, 3d ed., 1887; A. Horwicz, Psychologische Analysen auf physiologischer Grundlage, 1872 *seq.; Franz Brentano in Vienna (born 1838), Psychologie vom empirischen Standpunkte, vol. i. 1874; Carl Stumpf of Munich (born 1848), Ueber den psychologischen Ursprung der Raumvorstellung*, 1873, *Tonpsychologie, vol. i. 1883, vol. ii. 1890; Theodor Lipps of Breslau (born 1851), Grundthatsachen des Seelenlebens, 1883. The following may be mentioned in the same connection: J.H. Witte, Das Wesen der Seele, 1888; H. Münsterberg, Die Willenshandlung, 1888, Beiträge zur experimentellen Psychologie, 1889 seq,; Goswin K. Uphues at Halle, Wahrnehmung und Empfindung, 1888, Ueber die Erinnerung, 1889; H. Schmidkunz, Psychologie der Suggestion, 1892; H. Ebbinghaus, the co-editor of the Zeitschrift für Psychologie una Physiologie der Sinnesorgane*, 1890 seq.; H. Spitta; Max Dessoir, *Der Hautsinn, in the Archiv für Anatomie una Physiologie, 1892. The following works are psychological contributions to the theory of knowledge: E.L. Fischer, Theorie der Gesichtswahrnehmung, 1891; Hermann Schwarz, Das Wahrnehmungsproblem, 1892. Finally we may add A. Dorner in Königsberg, Das menschliche Erkennen, 1887; and E.L. Fischer, Die Grundfragen der Erkenntnisstheorie, 1887.
The literature of moral philosophy has been substantially enriched by Wundt, Ethik, 1886, 2d ed., 1892; and Friedrich Paulsen, System der Ethik, 1889, 2d ed., 1891. We may mention, further, Baumann (p. 601); Schuppe, Grundzüge der Ethik und Rechtsphilosophie, 1882; Witte, Freiheit des Willens, 1882; G. Class in Erlangen, Ideale und Güter, 1886; Richard Wallaschek, Ideen zur praktischen Philosophic, 1886; F. Tönnies in Kiel, Gemeinschaft und Gesellschaft, 1887; A. Döring, Philosophische Güterlehre, 1888; Th. Ziegler, Sittliches Sein und Werden*, 2d ed., 1890; G. Simmel, *Einleitung in die Moralwissenschaft, vol. i. 1892.
Of the newer works in the field of aesthetics, in addition to A. Zeising's Aesthetische Forschungen, 1855, C. Hermann's Aesthetik, 1875, and Hartmann's Philosophie des Schönen, 1887, we may mention the Einleitung in die Aesthetik of Karl Groos, 1892, and the following by Lipps: Der Streit über die Tragödie, 1890; Aesthetische Faktoren der Raumanschauung*, 1891; the essay Psychologie der Komik (Philosophische Monatshefte, vols. xxiv.-xxv. 1888-89), and Aesthetische Litteraturberichte, (in the same review, vol. xxvi. 1890 *seq.).
Among the writers and works on the philosophy of history we may note Conrad Hermann in Leipsic (born 1819), Philosophie der Geschichte, 1870; Bernheim, Geschichtsforschung und Geschichtsphilosophie, 1880; Karl Fischer, Ist eine Philosophie der Geschichte wissenschaftlich erforderlich bezw. möglich?* Dillenburg Programme, 1889; Hinneberg, Die philosophischen Grundlagen der Geschichtswissenschaft in Sybel's Historische Zeitschrift, vol. lxiii. 1889; A. Dippe, Das Geschichtsstudium mit seinen Zielen und Fragen, 1891; Georg Simmel, *Die Probleme der Geschichtsphilosophie, 1892.
In the philosophy of religion, which is discussed especially by the theologians, a neo-Kantian and a neo-Hegelian tendency confront each other. The former, dividing in its turn, is represented, on the one hand, by the Ritschlian school--W. Herrmann in Marburg (Die Metaphysik in der Theologie*, 1876, Die Religion im Verhältniss zum Welterkennen und zur Sittlichkeit, 1889), J. Kaftan in Berlin (*Das Wesen der christlichen Religion, 1881)--and, on the other, by R.A. Lipsius in Jena (born 1830; Dogmatik, 1876, 2d ed., 1879; Philosophie und Religion, 1885). The latter is represented by A.E. Biedermann of Zurich (1819-85; Christliche Dogmatik, 1868; 2d ed., 1884-85), a pupil of W. Vatke, and by Otto Pfleiderer of Berlin (born 1839; Religionsphilosophie, 1879; 2d ed., 1883-4). The neo-Kantians base religion exclusively on the practical side of human nature, especially on the moral law, derive it from the contrast between external dependence on nature and the inner freedom or supernatural destination of the spirit, and wish it preserved from all intermixture with metaphysics. According to the neo-Hegelians, on the contrary, the theoretical element in religion is no less essential; and is capable of being purified, of being elevated from the form of representation, which is full of contradictions, into the adequate form of pure thought, capable, therefore, of reconciliation with philosophy. Hugo Delff (Ueber den Weg zum Wissen und zur Gewissheit zu gelangen*, 1882; *Die Hauptprobleme der Philosophie und Religion, 1886) follows Jacobi's course.
Among the numerous works on the history of philosophy, besides the masterpieces of Zeller, J.E. Erdmann, and Kuno Fischer, the following are especially worthy of attention:
Cl. Bäumker in Breslau, Das Problem der Materie in der griechischen Philosophie*, 1890; H.

%4. Retrospect.%
In order to avoid the appearance of arbitrary construction we have been sparing with references of a philosophico-historical character. In conclusion, looking back at the period passed over, we may give expression to some convictions concerning the guiding threads in the development of modern philosophy, though these here claim only the rights of subjective opinion.
A mirror of modern culture, and conscious of its sharp antithesis to Scholasticism, modern philosophy in its pre-Kantian period is pre-eminently characterized by naturalism. Nature, as a system of masses moved according to law, forms not only the favorite object of investigation, but also the standard by which psychical reality is judged and explained. The two directions in which this naturalism expresses itself, the mechanical view of the world, which endeavors to understand the universe from the standpoint of nature and all becoming from the standpoint of motion, and the intellectualistic view, which seeks to understand the mind from the standpoint of knowledge, are most intimately connected. Where the general view of the All takes form and color from nature, a content and a mission can come to the mind from no other source than the external world; whether we (empirically) make it take up the material of representation from without or (rationalistically) make it create an ideal reproduction of the content of external reality from within, it is always the function of knowledge, conceived as the reproduction of a completed reality, which, since it brings us into contact with nature, advances into the foreground and determines the nature of psychical activity. As is conceivable, along with dogmatic faith in the power of the reason to possess itself of the reality before it and to reconstrue it in the system of science, and with triumphant references to the mathematical method as a guaranty for the absolute certainty of philosophical knowledge, the noëtical question emerges as to the means by which, and the limits within which, human knowledge is able to do justice to this great problem. Descartes gave out the programme for all these various tendencies--the mechanical explanation of nature, the absolute separation of body and soul (despiritualization of matter), thought the essence of the mind, the demand for certain knowledge, armed against every doubt, and the question as to the origin of ideas. Its execution by his successors shows not only a lateral extension in the most various directions (the dualistic view of the world held by the occasionalists, the monistic or pantheistic view of Spinoza, the pluralistic or individualistic view of Leibnitz; similarly the antithesis between the sensationalism of Locke and Condillac and the rationalism of Spinoza and Leibnitz), but also a progressive deepening of problems, mediated by party strife which puts every energy to the strain. What a tremendous step from the empiricism of Bacon to the skepticism of Hume, from the innate ideas of Descartes to the potential a priori of Leibnitz! From the moment when the negative and positive culminations of the pre-Kantian movement in thought--Hume and Leibnitz--came together in one mind, the conditions of the Kantian reform were given, just as the preparation for the Socratic reform had been given in the skepticism of the Sophists and the [Greek: nous] principle of Anaxagoras.
Kant, who dominates the second period of modern philosophy down to the present time, is related to his predecessors in a twofold way. In his criticism he completes the noëtical tendency, and at the same time overcomes naturalism, by limiting the mechanical explanation (and with it certain knowledge, it is true) to phenomena and opposing moralism to intellectualism. Nature must be conceived from the standpoint of the spirit (as its product, for all conformity to law takes its origin in the spirit), the spirit from the standpoint of the will. Metaphysics, as the theory of the a priori conditions of experience, is raised to the rank of a science, while the suprasensible is removed from the region of proof and refutation and based upon the rock of moral will. In the positive side of the Kantian philosophy--the spirit the law-giver of nature, the will the essence of spirit and the key to true reality--we find its kernel, that in it which is forever valid. The conclusions on the absolute worth of the moral disposition, on the ultimate moral aim of the world, on the intelligible character, and on radical evil, reveal the energy with which Kant took up the mission of furnishing the life-forces opened up by Christianity--which the Middle Ages had hidden rather than conserved under the crust of Aristotelian conceptions entirely alien to them, and the pre-Kantian period of modern times had almost wholly ignored--an entrance into philosophy, and of transforming and enriching the modern view of the world from this standpoint. Kant's position is as opposite and superior to the specifically modern, to the naturalistic temper of the new period, as Plato stands out, a stranger and a prophet of the future, above the level of Greek modes of thought. More fortunate, however, than Plato, he found disciples who followed further in the direction pointed out by that face of the Janus-head of his philosophy which looked toward the future: the ethelism of Fichte and the historicism of Hegel have their roots in Kant's doctrine of the practical reason. These are acquisitions which must never be given up, which must ever be reconquered in face of attack from forces hostile to spirit and to morals. In life, as in science, we must ever anew "win" ethical idealism "in order to possess it." As yet the reconciliation of the historical and the scientific, the Christian and the modern spirit is not effected. For the inbred naturalism of the modern period has not only asserted itself, amalgamated with Kantian elements, in the realistic metaphysics and mechanical psychology of Herbart and in the system of Schopenhauer, as a lateral current by the side of Fichte, Schelling, and Hegel, but, under the influence of the new and powerful development of the natural sciences, has once more confidently risen against the traditions of the idealistic school, although now it is tempered by criticism and concedes to the practical ideals at least a refuge in faith. The conviction that the rule of neo-Kantianism is provisional does not rest merely on the mutability of human affairs. The widespread active study of the philosophy of the great Königsberger gives ground for the hope that also those elements in it from which the systems of the idealists have proceeded as necessary consequences will again find attention and appreciation. The perception of the fact that the naturalistico-mechanical view represents only a part, a subordinate part, of the truth will lead to the further truth, that the lower can only be explained by the higher. We shall also learn more and more to distinguish between the permanent import of the position of fundamental idealism and the particular form which the constructive thinkers have given it; the latter may fall before legitimate assaults, but the former will not be affected by them. The revival of the Fichteo-Hegelian idealism by means of a method which shall do justice to the demands of the time by a closer adherence to experience, by making general use of both the natural and the mental sciences, and by an exact and cautious mode of argument--this seems to us to be the task of the future. The most important of the post-Hegelian systems, the system of Lotze, shows that the scientific spirit does not resist reconciliation with idealistic convictions in regard to the highest questions, and the consideration which it on all sides enjoys, that there exists a strong yearning in this direction. But when a deeply founded need of the time becomes active, it also rouses forces which dedicate themselves to its service and which are equal to the work.
