Fichte's chief interest was centred upon the ego; nature he regarded as a product of the absolute ego in the individual consciousness, intended as a necessary obstacle for the free will. Without opposition the self cannot act; without overcoming resistance it cannot become free. In order to make free action possible, to enable the ego to realize its ends, nature must be what it is, an order ruled by the iron law of causality. This cheerless conception of nature—which, however, was not Fichte's last word on the subject, since he afterward came to conceive it as the revelation of universal life, or the expression of a pantheistic God—did not attract Romanticism. It was Schelling, the erstwhile follower and admirer of Fichte, who turned his attention to the philosophy of nature and so more thoroughly satisfied the romantic yearnings of the age.

Friedrich Wilhelm Joseph Schelling was born at Leonberg, Würtemberg, January 27, 1775, the son of a learned clergyman and writer on theology. He was a precocious child and made rapid progress in his studies, entering the Theological Seminary at Tübingen at the age of fifteen. Between the ages of nineteen and twenty-two he wrote a number of able treatises in the spirit of the new idealism, and was recognized as the most talented pupil of Fichte and his best interpreter. After the completion of his course at the University (1795), he became the tutor and companion of two young noblemen with whom he remained for two years (1796-98) at the University of Leipzig, during which time he devoted himself to the study of mathematics, physics, and medicine, and published a number of philosophical articles. In 1798 he received a call to a professorship at Jena, where Fichte, Schiller, Wilhelm Schlegel, and Hegel became his colleagues, and where he entered into friendly relations with the Romantic circle of which Caroline Schlegel, who afterward became his wife, was a shining light. This was the most productive period of his life; during the next few years he developed his own system of philosophy and gave to the world his most brilliant writings. In 1803 he accepted a professorship at Würzburg, but came into conflict with the authorities; in 1806 he went to Munich as a member of the Academy of Sciences and Director of the Academy of Fine Arts; in 1820 he moved to Erlangen; and in 1827 he returned to Munich as professor of philosophy at the newly-established University and as General Curator of the Scientific Collections of the State. He was called to Berlin in 1841 to help counteract the influence of the Hegelian Philosophy, but met with little success. He died in 1854.

The earlier writings of Schelling either reproduced the thoughts of the Wissenschaftslehre or developed them in the Fichtean spirit. Among those of the latter class we note: Ideas for a Philosophy of Nature, 1797; On the World-Soul, 1798; System of Transcendental Idealism, 1800. During the second period, in which the influence of Bruno and Spinoza is prominent, he works out his own philosophy of identity; at this time he publishes Bruno, or, Concerning the Natural and Divine Principle of Things, 1802, and Method of Academic Study, 1803. In the third period the philosophy of identity becomes the basis for a still higher system in which the influence of German theosophy (Jacob Böhme) is apparent; with the exception of Philosophy and Religion, 1804, the Treatise on Human Freedom, 1809, and a few others, the works of this period did not appear until after Schelling's death. His previous philosophy is now called by him "negative philosophy;" the higher or positive philosophy has as its aim the rational construction of the history of the universe, or the history of creation, upon the basis of the religious ideas of peoples; it is a philosophy of mythology and revelation. Translations of some of Schelling's works are to be found in the Journal of Speculative Philosophy, an American periodical founded by W.T. Harris, which devoted itself to the study of post-Kantian idealism. His Complete Works, edited by his son, appeared in 14 volumes, 1856. There is a revival of interest in his philosophy, and new editions of his books are now being published.

Like most philosophers of note, Schelling reckons with the various tendencies of his times. With idealism he interprets the universe as identical in essence with what we find in our innermost selves; it is at bottom a living dynamic process. If that is so, nature cannot be a merely externalized obstacle for the ego, nor a dead static spatial mechanical system; as the expression of an active spiritual principle there must be reason and purpose in it. But reason is not identified by Schelling with self-conscious intelligence, for with the faith-philosophies and Romanticism he takes it in a wider sense; in physical and organic nature it is a slumbering reason, an unconscious, instinctive, purposive force similar to the Leibnizian monad, Schopenhauer's will, and Bergson's élan vital. In this way the dualism between mechanism and teleology is reconciled. Nature is a teleological order, an evolution from the unconscious to the conscious; in man, the highest stage and the climax of history, nature becomes self-conscious. With this organic conception both Romanticists and many natural scientists of the age were in practical agreement; it was the view that had always appealed to Goethe—and Herder before him—and it gained for Schelling a large following. In his earlier system he regarded nature as a lower stage in the evolution of reason and sought to answer the problems: How does Nature become Consciousness or Ego? the problem of the Philosophy of Nature; and, How does Consciousness or the Ego become Nature? the problem of Transcendental Idealism. In his philosophy of identity, nature and mind are conceived as two different aspects of one and the same principle, which is both mind and nature, subject and object, ego and non-ego. All things are identical in essence but differentiated in the course of evolution. It was not inconsistent with these tenets that Schelling sought, in his last period, to discover the meaning of universal history in the obscure beginnings of mythology and revelation rather than in the lucid regions of an advanced civilization.

With the opponents of rationalism Schelling agrees that we cannot reach the inner meaning of reality, "the living, moving element in nature," through the scientific intelligence, but that we must envisage it in intuition. "What is described in concepts," he tells us, "is at rest; hence there can be concepts only of things and of that which is finite and sense-perceived. The notion of movement is not movement itself, and without intuition we should never know what motion is. Freedom, however, can be comprehended only by freedom, activity only by activity." Schelling, who is a poet as well as a philosopher, comes to regard this intuition or inner vision as an artistic intuition. In the products of art, subject and object, the ideal and the real, mind and nature, form (or purpose) and matter, are one; here the harmony aimed at by philosophy lies before our very eyes, and may be seen, touched, and heard. The creative artist creates like nature in realizing the ideal; hence, art must serve as the absolute model for the intuition of the world—it is the true and eternal organ of philosophy. Like the artistic genius, the philosopher must have the faculty for perceiving the harmony and identity in the universe; esthetic intuition is absolute knowing. Art aims to reveal to us the profoundest meaning of the world, which is the union of form and matter, of the ideal and the real; in art alone the striving of nature for harmony and identity is realized; the beautiful is the infinite represented and made perceivable in finite form; here mind and nature interpenetrate. In creative art the artist imitates the creative act of nature and becomes conscious of it; in esthetic intuition, or the perception of beauty, the philosophical genius discovers the secret of reality; nature herself is a poem and her secret is revealed in art. This philosophy is a far cry from the logical-mathematical method of the Aufklärung; it is a protest against this, a protest in which the leaders of the new German literature, Herder, Goethe, Schiller, as well as the Romanticists, willingly joined. Goethe's entire view of nature, art, and life rested upon the teleological or organic conception; he, too, regarded the ability to peer into the heart of things—to see the whole in its parts, the ideal in the real, the universal in the particular, as the poet's and thinker's highest gift. He called it an aperçu, "a revelation springing up in the inner man that gives him a hint of his likeness to God." It is this gift which Faust craves and Mephisto sneers at as die hohe Intuition.

  Im innersten zusammenhält,
  Schau alle Wirkungskraft and Samen
  Und tu' nicht mehr in Worten kramen.
 

There was much that was fantastic in the Naturphilosophie and much a priori interpretation of nature that tended to withdraw the mind from the actualities of existence; it often dealt with bold assertions, analogies, and figures of speech, rather than with facts and proofs. But it had its merits; for it aroused an interest in nature and nature-study, it kept alive the philosophical interest in the outer world, the desire for unity, Einheitstrieb, which has remained a marked characteristic of German science from Alexander von Humboldt down to Robert Mayer, Helmholtz, Naegeli, Haeckel, Ostwald, Hertz, and Driesch. It opposed the one-sided mechanical method of science, and emphasized conceptions (the idea of development, the notion of the dynamic character of reality, pan-psychism, and vitalism) which are still moving the minds of men today, as is evidenced by the popularity of Henri Bergson, who, with our own William James, leads the contemporary school of philosophical Romanticists.

Fichte's chief contribution to German thought was the Wissenschaftslehre, Schelling's the Naturphilosophie, and Schleiermacher's the philosophy of religion. All these thinkers took account of the prevailing tendencies of the times—Aufklärung, Kantian criticism, faith-philosophy, Romanticism, and Spinozism—and were more or less affected by them. Schleiermacher also came under the influence of Fichte, Schelling, and Greek idealism, particularly of Plato's philosophy; many were the sources from which he drew his material for the construction of a great system of Protestant theology that exercised a profound influence far beyond the boundaries of his country and won for him the title of the founder of the New Theology.

Friedrich Daniel Ernst Schleiermacher, the son of a clergyman of the reformed church, was born at Breslau, November 21, 1768, and was educated at the Moravian schools at Niesky and Barby. Made sceptical by the newer criticism, he left the Moravian brotherhood and entered the University of Halle (1787), where he devoted himself with equal zeal to the study of theology and philosophy. After his ordination in 1794 he occupied various pulpits until 1803, when he was made a professor and university preacher at Halle. In 1806 he removed from Halle to Berlin, becoming the preacher of Trinity Church in 1809 and professor of theology at the newly founded University in 1810, positions which he filled with marked ability until his death, February 12, 1834. It was in Berlin that he came into friendly touch with the leaders of the Romantic school, Tieck, Friedrich Schlegel, and Novalis, but he did not allow himself to be carried away by their extravagances. He distinguished himself as a preacher, theologian, philosopher, and philologist, and, by his study of the sources of philosophy, added much to the knowledge of its history. Among the books published during his life-time are: Addresses on Religion, 1799; Monologues, 1800; Principles of a Criticism of Previous Systems of Ethics, 1803; translations of Plato's Dialogues, with introductions and notes, 1804-28; The Christian Faith, 1821-22. Complete Works, 1834-64.

Schleiermacher's conception of religion is opposed to the rationalistic theology of the eighteenth century, as well as to the Kantian moral theology which has remained popular in Germany to this day. For him religion is not science or philosophy; it does not consist in theoretical dogmas or rationalistic proofs; neither theories about religion nor virtuous conduct nor acts of worship are religion itself; nor is religion based upon a rational moral faith, as Kant had taught. He bravely took the part of Fichte in the atheism-controversy, when the great leaders of German culture, Kant, Herder, and even Goethe, abandoned him to his fate. He rejected the shallow proofs of the Aufklärung, as well as the orthodox utilitarian view of God as the dispenser of rewards and punishments, and showed that the real foes of religion were the rational and practical persons who endeavored to suppress the yearning for the transcendent in man and to drive out all mystery in seeking to make everything clear to him. We cannot have conceptual knowledge of God, for conceptual thought is concerned with differences and opposites, whereas God is without such differences and oppositions: he is the absolute union or identity of thought and being. Religion is grounded in feeling, or divining intuition; in feeling, we come into direct relation with God; here the identity of thought and being is immediately experienced in self-consciousness, and this union is the divine element in us. Religion is the feeling of absolute dependence upon an absolute world-ground; it is the immediate consciousness that everything finite is infinite and exists through the infinite.

The conception of God as the unity of thought and being, and the idea of man's absolute dependence upon the world-ground, call to mind the pantheism of Spinoza. Schleiermacher seeks to tone this down by giving the world of things a relative independence; God and the world are inseparable, and yet must be distinguished. God is unity without plurality, the world plurality without unity; the world is spatial-temporal, while God is spaceless and timeless. He is, however, not conceived as a personality, but as the universal creative force, as the source of all life. The determinism implied in this world-view is softened by giving the individual a measure of freedom and independence. The particular individuals are subject to the law of the whole; but each self has its unique endowment or gifts, its individuality, and its freedom consists in the unfolding of its peculiar capacities. With Goethe, Schiller, and Romanticism, our philosopher rejects the rigoristic Kantian-Fichtean view of duty which, in his opinion, would suppress individuality and reduce all persons to a homogeneous mass; like them he regards the development of unique personalities as the highest moral task. "Every man should express humanity in his own peculiar way in a unique mixture of elements, in order that it may reveal itself in every possible form, and that everything may become real in the infinite fulness which can spring from its lap." "The same duties can be performed in many different ways. Different men may practise justice according to the same principles, each man keeping in view the general welfare and personal merit, but with different degrees of feeling, all the way from extreme coldness to the warmest sympathy." The command, therefore, is not merely: Be a person; but: Be a unique person, live your own individual life. There is no irreconcilable conflict between the natural law and the moral law, between impulse and reason. For the same reasons he defends the diversity of religions and the claims of personal religion; in each unique individual, religion should be left free to express itself in its own unique and intimate way. His ideal is the development of unique, novel, original personalities; and these are expressions of the divine, which rationalism cannot bring under either its theoretical or practical rubrics.

The individual cannot become conscious of, and prize, his own individuality without at the same time valuing uniqueness in others; the higher a value he sets upon his own self, the more the personalities of others must impress him. "Whoever desires to cultivate his individuality must have an appreciation of everything that he is not." "The sense of universality (der allgemeine Sinn) is the supreme condition of one's own perfection." Hence the ethical life is a life in society—a society of unique individuals who respect humanity in its uniqueness, in themselves and in others. "They are among themselves a chorus of friends. Every one knows that he too is a part and product of the universe, that in him too are revealed its divine life and action." "The more every one approximates the universe, the more he communicates himself to others, the more perfect unity will they all form; no one has a consciousness for himself alone, every one has, at the same time, that of the other; they are no longer only men, but mankind; rising above themselves and triumphing over themselves, they are on the road to true immortality and eternity." In the feeling of piety man recognizes that his desire to be a unique personality is in harmony with the action of the universe; hence that he can, ought, and must make the development of his uniqueness the goal, the strongest motive, and the highest good, and that he can surely realize what he is striving for, because the universe which created and determined him created him for that.
