is represented, on the one hand, by the Ritschlian schoolW. 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 neoHegelians, 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 Phil osophie und Religion, 1886) follows Jacobi's course.

4. Retrospect.

In order to avoid the appearance of arbitrary construction we have been sparing with references of a philosophicohistorical 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 Leib* Even for Leibnitz the mind is a machine (automaton spirituale), and psychical action a movement of ideas.

nitz; 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 vous 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 lawgiver 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 lifeforces 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 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 pyschology 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.
