With the exception of this divergence in method Fries accepts Kant's results almost unchanged, unless we must call the leveling down which they suffer at his hands a considerable alteration. Only the doctrine of the Ideas and of the knowledge of reason is transformed by the introduction and systematization of Jacobi's principle of the immediate evidence of faith. Reason, the faculty of Ideas, i.e., of the indemonstrable yet indubitable principles, is fully the peer of the sensibility and the understanding. The same subjective necessity which guarantees to us the objective reality of the intuitions and the categories accompanies the Ideas as well; the faith which reveals to us the per se of things is no less certain than the knowledge of phenomena. The ideal view of the world is just as necessary as the natural view; through the former we cognize the same world as through the latter, only after a higher order; both spring from reason or the unity of transcendental apperception, only that in the natural view we are conscious of the fact, from which we abstract in the ideal view, that this is the condition of experience. That which necessitates us to rise from knowledge to faith is the circumstance that the empty unity-form of reason is never completely filled by sensuous cognition. The Ideas are of two kinds: the aesthetic Ideas are intuitions, which lack clear concepts corresponding to them; the logical Ideas are concepts under which no correspondent definite intuitions can be subsumed. The former are reached through combination; the latter by negation, by thinking away the limitations of empirical cognition, by removing the limits from the concepts of the understanding. By way of the negation of all limitations we reach as many Ideas as there are categories, that is, twelve, among which the Ideas of relation are the most important. These are the three axioms of faith—the eternity of the soul (its elevation above space and time, to be carefully distinguished from immortality, or its permanence in time), the freedom of the will, and the Deity. Every Idea expresses something absolute, unconditioned, perfect, and eternal.—The dualism of knowledge and faith, of nature and freedom, or of phenomenal reality and true, higher reality, is bridged over by a third and intermediate mode of apprehension, feeling or presentiment, which teaches us the reconciliation of the two realities, the union of the Idea and the phenomenon, the interpenetration of the eternal and the temporal. The beautiful is the Idea as it manifests itself in the phenomenon, or the phenomenon as it symbolizes the eternal. The aesthetico-religious judgment looks on the finite as the revelation and symbol of the infinite. In brief, "Of phenomena we have knowledge; in the true nature of things we believe; presentiment enables us to cognize the latter in the former."
Theoretical philosophy is divided into the philosophy of nature, which is to use the mathematical method, hence to give a purely mechanical explanation of all external phenomena, including those of organic life, and to leave the consideration of the world as a teleological realm to religious presentiment—and psychology. The object of the former is external nature, that of the latter internal nature. I know myself only as phenomenon, my body through outer, my ego through inner, experience. It is only a variant mode of appearing on the part of one and the same reality—so Fries remarks in opposition to the influxus physicus and the harmonia praestabilata—which now shows me my person inwardly as my spirit, and now outwardly as the life-process of my body. Practical philosophy includes ethics, the philosophy of religion, and aesthetics. In accordance with the threefold interest of our animal, sensuo-rational, and purely rational impulses, there result three ideals for the legislation of values. These are the ideal of happiness, the ideal of perfection, and the ideal of morality, or of the agreeable, the useful, and the good, the third of which alone possesses an unconditioned worth and validity as a universal and necessary law. The moral laws are deduced from faith in the equal personal dignity of men, and the ennobling of humanity set up as the highest mission of morality. The three fundamental aesthetical tempers are the idyllic and epic of enthusiasm, the dramatic of resignation, the lyric of devotion.
Fries's system is thus a union of Kantian positions with elements from Jacobi, in which the former experience deterioration, and the latter improvement, namely, more exact formulation. Among his adherents, and he has them still, the following appear deserving of mention: the botanists Schleiden and Hallier; the theologian De Wette; the philosophers Calker (of Bonn, died 1870) and Apelt (1812-59). The last made himself favorably known by his Epochs of the History of Humanity, 1845-46, Theory of Induction, 1854, and Metaphysics, 1857; his Philosophy of Religion (1860) did not appear until after his death. The Catholic theologian, Georg Hermes of Bonn (1775-1831) favored a Kantianism akin to that of Fries.

The psychological view founded by Fries was consistently developed by Friedrich Eduard Beneke (1798-1854). With the exception of three years of teaching in Göttingen, 1824-27, whither he had gone in consequence of a prohibition of his lectures called forth by his Foundation of the Physics of Ethics, 1822, he was a member of the university of his native city, Berlin, first as Docent, and, from 1832, after the death of Hegel, who was unfavorably disposed toward him, as professor extraordinary.[1] Besides Kant, Jacobi, and Fries, Schleiermacher, Herbart (with whom he became acquainted in 1821), and the English thinkers exerted a determining influence on the formation of his philosophy. Beneke denies the possibility of speculative knowledge even more emphatically than Fries. Kant's undertaking was aimed at the destruction of a non-experiential science from concepts, and if it has not succeeded in preventing the neo-Scholasticism of the Fichtean school, with its overdrawn attempts to revive a deductive knowledge of the absolute, this has been chiefly due to the false, non-empirical method of the great critic of reason. The root and basis of all knowledge is experience; metaphysics itself is an empirical science, it is the last in the series of philosophical disciplines. Whoever begins with metaphysics, instead of ending with it, begins the house at the roof. The point of departure for all cognition is inner experience or self-observation; hence the fundamental science is psychology, and all other branches of philosophy nothing but applied psychology. By the inner sense we perceive our ego as it really is, not merely as it appears to us; the only object whose per se we immediately know is our own soul; in self-consciousness being and representation are one. Thus, in opposition to Kant, Beneke stands on the side of Descartes: The soul is better known to us than the external world, to which we only transfer the existence immediately given in the soul as a result of instinctive analogical inference, so that in the descent of our knowledge from men organized like ourselves to inorganic matter the inadequacy of our representations progressively increases.
[Footnote 1: On Beneke's character cf. the fourth of Fortlage's Acht psychologische Vorträge, which are well worth reading.]
Psychology—we may mention of Beneke's works in this field the Psychological Sketches, 1825-27, and the Text-book of Psychology, 1833, the third and fourth (1877) editions of which, edited by Dressler, contain as an appendix a chronological table of all Beneke's works—must, as internal natural science, follow the same method, and, starting with the immediately given, employ the same instruments in the treatment of experience as external natural science, i.e. the explanation of facts by laws, and, further still, by hypotheses and theories. Gratefully recognizing the removal of two obstacles to psychology, the doctrine of innate ideas and the traditional theory of the faculties of the soul by Locke and Herbart, (the commonly accepted faculties—memory, understanding, feeling, will—are in fact not simple powers, but mere abstractions, hypostatized class concepts of extremely complex phenomena,) Beneke seeks to discover the simple elements from which all mental life is compounded. He finds these in the numerous elementary faculties of receiving and appropriating external stimuli, which the soul in part possesses, in part acquires in the course of its life, and which constitute its substance; each separate sense of itself includes many such faculties. Every act or product of the soul is the result of two mutually dependent factors: stimulus and receptivity. Their coming together gives the first of the four fundamental processes, that of perception. The second is the constant addition of new elementary faculties. By the third, the equilibration or reciprocal transfer of the movable elements in representations, Beneke explains the reproduction of an idea through another associated with it, and the widening of the mental horizon by emotion, e.g., the astounding eloquence of the angry. Since each representation which passes out of consciousness continues to exist in the soul as an unconscious product (where we cannot tell; the soul is not in space), it is not retention, but obliviscence which needs explanation. That which persists of the representation which is passing into unconsciousness, and which makes its reappearance in consciousness possible, is called a "trace" in reference to its departed cause, and a "disposition" (Angelegtheit) in reference to its future results. Every such trace or germ (Anlage)—that which lies intermediate between perception and recollection—is a force, a striving, a tendency. The fourth of the fundamental processes (which may be traced downward into the material world, since the corporeal and the psychical differ only in degree and pass over into each other) is the combination of mental products according to the measure of their similarity, as these come to light in the formation of judgments, comparisons, witticisms, of collective images, collective feelings, and collective desires. The innate differences among men depend on the greater or lesser "powerfulness, vivacity, and receptivity" of their elementary faculties; all further differences arise gradually and are due to the external stimuli; even the distinction between the human and the animal soul, which consists in the spiritual nature of the former, is not original.
Of the five constructive forms of the soul, which result from the varying relation between stimulus and faculty, four are emotional products or products of moods. If the stimulus is too small pain (dissatisfaction, longing) arises, while pleasure springs from a marked, but not too great, fullness of stimulus. If the stimulus gradually increases to the point of excess, blunted appetite and satiety come in; when the excess is sudden it results in pain. A clear representation, a sensation arises when the stimulus is exactly proportioned to the faculty; it is in this case only that the soul assumes a theoretical attitude, that it merely perceives without any admixture of agreeable or disagreeable feelings. Desire is pleasure remembered, the ego the complex of all the representations which have ever arisen in the soul, the totality of the manifold given within me. For the immortality of the immaterial soul Beneke advances an original and attractive argument based on the principle that, in consequence of the constantly increasing traces, through which the substance of the soul is continually growing, consciousness turns more and more from the outer to the inner, until finally perception dies entirely away. At death the connection with the outer world ceases, it is true, but not the inner being of the soul, for which that which has hitherto been highest now becomes the foundation for new and still higher developments.
Like Herbart, on whom he was in many ways dependent, Beneke discussed psychology and pedagogics with greater success than logic, metaphysics, practical philosophy, and the philosophy of religion. He combats the apriorism of Kant in ethics as elsewhere. The moral law does not arise until the end of a long development. First in order are the immediately felt values of things, which we estimate according to the degree of enhancement or depression in the psychical state which they call forth. From the feelings are formed concepts, from concepts judgments; and the abstraction of the categorical imperative is a highly derivative phenomenon and a very late result, although the feeling of oughtness or of moral obligation, which accompanies the correct estimation of values and bids us prefer spiritual to sensuous delights and the general good to our own welfare, grows necessarily out of the inner nature of the human soul. There are two sources of religion: one theoretical, for the idea of God; the other practical, for the worship of God. We are impelled to the assumption of a suprasensible, an unconditioned, a providence, on the one hand, by the desire for a unitary conclusion for our fragmentary knowledge of the world; and, on the other, by moral need, by our unsatisfied longing after the good. The attributes which we ascribe to God are taken from experience, the abstract attributes from being in general, the naturalistic from the world, the spiritual from man. As an inevitable outcome of the transformation of religious feelings into representations, and one which is harmless because of the unmistakableness of their symbolic character, the anthropomorphic predicates, through which we think the Deity as personal, themselves establish the superiority of theism over pantheism. The object of religion, moreover, is accessible only to the subjective certitude of feeling which is given by faith, and not to scientific knowledge.
Feuerbach's anthropological standpoint will be discussed below. Like Friedrich Ueberweg (1826-71; professor in Königsberg; System of Logic, 1857, 5th ed., edited by J.B. Meyer, 1882—English translation, 1871), Karl Fortlage was strongly influenced in his psychological views by Beneke. Born in 1806 at Osnabrück, and at his death in 1881 a professor in Jena, Fortlage shared with Beneke an impersonality of character, as well as the fate of meeting with less esteem from his contemporaries than he merited by the seriousness and originality of his thinking. To his System of Psychology, 1855, in two volumes, he added, as it were, a third volume, his Contributions to Psychology, 1875, besides psychological lectures of a more popular cast (Eight Lectures, 1869, 2d ed., 1872; Four Lectures, 1874).[1] Fortlage characterizes his psychological method—in the criticism of which F.A. Lange fails to show the justice for which he is elsewhere to be commended—as observation by the inner sense. In the first place, consciousness, as the active form of representation, must be separated from that of which we are conscious, from the "content of representation," which is in itself unconscious, but capable of coming into consciousness. Next Fortlage seeks to determine the laws of these two factors. In regard to the content of representation he distinguishes more sharply than Herbart between the fusibility of the homogeneous and the capacity for complex combination possessed by the heterogeneous (the fusion of similars goes on even without aid from consciousness, while the connection of dissimilars is brought about only through the help of the latter), and adds to these two general properties of the content of representation two further ones, its revivability (its persistence in unconsciousness), and its dissolubility in the scale of size, color, etc. Consciousness, on the other hand, which for Fortlage coincides with the ego or self, is treated as the presupposition of all representations, not as their result—it is underived activity. He explains the nature of consciousness by the concept of attention, characterizes them both as "questioning activity" (Fragethätigkeit), and follows them out in their various degrees from expectation through observation up to reflection. The listening and watching of the hunter when waiting for the game is only a prolongation of the same consciousness which accompanies all less exciting representations. The essential element in conscious or questioning activity is the oscillation between yes and no.
