The philosophers of feeling or faith stand in the same relation to the German Illumination as Rousseau to the French. Here also the rights of feeling are vindicated against those of the knowing reason. Among the distinguished representatives of this anti-rationalistic tendency Hamann led the way, Herder was the most prolific, and Jacobi the clearest. That the fountain of certitude is to be sought not in discriminating thought, but in intuition, experience, revelation, and tradition; that the highest truths can be felt only and not proved; that all existing things are incomprehensible, because individual—these are convictions which, before Jacobi defended them as based on scientific principles, had been vehemently proclaimed by that singular man, J.G. Hamann (died 1788) of Königsberg. From an unprinted review by Hamann, Herder drew the objections which his "Metacritique" raises against Kant's Critique of Reason—that the division of matter and form, of sensibility and understanding, is inadmissible; that Kant misunderstood the significance of language, which is just where sensibility and understanding unite, etc.
In Herder[1] (1744-1803: after 1776 Superintendent-General in Weimar) the philosophy of feeling gained a finer, more perspicuous and harmonious nature, who shared Lessing's interest in history and his tendency to hold fast equally to pantheism and to individualism. God is the all-one, infinite, spiritual (non-personal) primal force, which wholly reveals itself in each thing (God: Dialogues on the System of Spinoza, 1787). To the life, power, wisdom, and goodness of God correspond the life and perfection of the universe and of individual creatures, each of which possesses its own irreplaceable value and bears in itself its future in germ. Everywhere, one and the same life in an ascending series of powers and forms with imperceptible transitions. Always, an inner and an outer together; no power without organ, no spirit without a body. As thought is only a higher stage of sensation, which develops from the lower by means of language—reason, like sense, is not a productive but a receptive faculty of knowing, perceiving ("Vernehmen")—so the free process of history is only the continuation and completion of the nature-process (Ideas for the Philosophy of the History of Mankind, 1784 seq.). Man, the last child of nature and her first freedman, is the nodal point where the physical series of events changes into the ethical; the last member of the organisms of earth is at the same time the first in the spiritual development. The mission of history is the unfolding of all the powers which nature has concentrated in man as the compendium of the world; its law, that everywhere on our earth everything be realized that can be realized there; its end, humanity and the harmonious development of all our capacities. As nature forms a single great organism, and from the stone to man describes a connected development, so humanity is a one great individual which passes through its several ages, from infancy (the Orient), through boyhood (Eygpt and Phoenicia), youth (Greece), and manhood (Rome), to old age (the Christian world). The spirit stands in the closest dependence upon nature, and nature is concerned in history throughout. The finer organization of his brain, the possession of hands, above all, his erect position, make man, man and endow him with reason. Similarly it is natural conditions, climate, the character of the soil, the surrounding animal and vegetable life, etc., that play an essential part in determining the manners, the characters, and the destinies of nations. The connection of nature with history by means of the concept of development and through the idea that the two merely represent different stages of the same fundamental process, made Herder the forerunner of Schelling.

His polemic against Kant in the Metacritique, 1799 (against the Critique of Pure Reason), and the dialogue Calligone, 1800 (against the Critique of Judgment), is less pleasing. These are neither dignified in tone nor essentially of much importance. In the former the distinction between sensibility and reason is censured, and in the latter the separation of the beautiful from the true and the good, but Kant's theory of aesthetics is for the most part grossly misunderstood. The "disinterested" satisfaction Herder makes a cold satisfaction; the harmonious activity of the cognitive powers, a tedious, apish sport; the satisfaction "without a concept," judgment without ground or cause. The positive elements in his own views are more valuable. Pleasure in mere form, without a concept, and without the idea of an end, is impossible. All beauty must mean or express something, must be a symbol of inner life; its ground is perfection or adaptation. Beauty is that symmetrical union of the parts of a being, in virtue of which it feels well itself and gives pleasure to the observer, who sympathetically shares in this well-being. The charm and value of the Calligone lie more in the warmth and clearness with which the expressive beauty of single natural phenomena is described than in the abstract discussion.
Friedrich Heinrich Jacobi (1743-1819) gave the most detailed statement of the position of the philosophy of feeling, and the most careful proof of it. He was born in Düsseldorf, the son of a manufacturer; until 1794 he lived in his native place and at his country residence in Pempelfort; later he resided in Holstein, and, from 1805, in Munich, where, in 1807-13, he was president of the Academy of Sciences. Of his works, collected in five volumes, 1812-25, we are here chiefly concerned with the letters On the Doctrine of Spinoza, 1785; David Hume on Faith, or Idealism and Realism, 1787; and the treatise On Divine Things, 1811, which called out Schelling's merciless response, Memorial of Jacobi. Besides Hume and Spinoza, the sensationalism of Bonnet and the criticism of Kant had made the most lasting impression on Jacobi. His relation to Kant is neither that of an opponent nor of a supporter and popularizer. He declares himself in accord with Kant's critique of the understanding (the understanding is merely a formal function, one which forms and combines concepts only, but does not guarantee reality, one to which the material of thought must be given from elsewhere and for which the suprasensible remains unattainable); in regard to the critique of reason he raises the objection that it; makes the Ideas mere postulates, which possess no guarantee for their reality. The critique of sensibility appears to him still more unsatisfactory, as it does not explain the origin of sensations. Without the concept of the "thing-in-itself" one cannot enter the Kantian philosophy, and with it one cannot remain there. Fichte has drawn the correct conclusion from the Kantian premises; idealism is the unavoidable result of the Critique of Reason and foretold by; it as the Messiah was foretold by John the Baptist. And by the evil fruit we know the evil root: the idealistic theory is philosophical nihilism, for it denies the reality of the external world, as the materialism of Spinoza denies a transcendent God and the freedom of the will. Reality slips away from both these systems—they are the only consistent ones there are—material reality escaping from the former and suprasensible reality from the latter; and this must be so, because reality, of whatever kind it be, cannot be known, but only believed and felt. The actual, the existence of the noumenal as well as of the external world, even the existence of our own body, makes itself known to us through revelation alone; the understanding comprehends relations only; the certainty that a thing exists is attained only through experience and faith. Sense and reason are the organs of faith, and hence the true sources of knowledge; the former apprehends the natural, the latter, the supernatural, while for the understanding is left only the analysis and combination of given intuitions.
Philosophy as a science from concepts must necessarily prove atheistic and fatalistic. Conception and proof mean deduction from conditions. How shall that which has no cause from which to explain it, the unconditioned, God, and freedom, be comprehended and proved? Demonstration rises along the chain of causes to the universe alone, not to a transcendent Creator; mediate knowledge is confined to the sphere of conditioned being and mechanical becoming. The intuitive knowledge of feeling alone leads us beyond this, and along with the wonderful, the inconceivable power of freedom in ourselves, which is above all nature, shows us the primal source of all wonders, the transcendent God above us. The inference from our own spiritual, self-conscious, free personality to that of God is no unauthorized anthropomorphism—in the knowledge of God we may fearlessly deify our human existence, because God, when he created man, gave his divine nature human form. Reason and freedom are the same: the former is theoretical, the latter practical elevation to the suprasensible. Nevertheless virtue is not based upon an inflexible, despotic, abstractly, formal law, but upon an instinct, which, however, does not aim at happiness. Thus Jacobi attempts to mediate between the ethics of the Illumination and the ethics of Kant, by agreeing with the former in regard to the origin of virtue (it arises from a natural impulse), and with the latter in regard to its nature (it consists in disinterestedness). Hence with the Illumination he rejects the imperative form, and with Kant the eudemonistic end. At the same time he endeavors to introduce Herder's idea of individuality into ethics, by demanding that morality assume a special form in each man. Schiller and the romantic school take from Jacobi their ideal of the "beautiful soul," which from natural impulse realizes in its action, and still more in its being, the good in an individual way.

CHAPTER IX.
KANT.
The suit between empiricism and rationalism had continued for centuries, but still awaited final decision. Are all our ideas the result of experience, or are they (wholly or in part) an original possession of the mind? Are they received from without (by perception), or produced from within (by self-activity)? Is knowledge a product of sensation or of pure thought? All who had thus far taken part in this discussion had resembled partisans or advocates rather than disinterested judges. They had given less attention to investigation than to the defense of the traditional theses of their schools; they had not endeavored to obtain results, but to establish results already determined; and, along with real arguments, popular appeals had not been despised. Each of the opposing schools had given variations on a definite theme, and whenever timid attempts had been made to bring the two melodies into harmony they had met with no approval. The proceedings thus far had at least made it evident to the unbiased hearer that each of the two parties made extravagant claims, and, in the end, fell into self-contradiction. If the claim of empiricism is true, that all our concepts arise from perception, then not only the science of the suprasensible, which it denies, but also the science of the objects of experience, about which it concerns itself, is impossible. For perception informs us concerning single cases merely, it can never comprehend all cases, it yields no necessary and universal truth; but knowledge which is not apodictically valid for every reasoning being and for all cases is not worthy the name. The very reasons which were intended to prove the possibility of knowledge give a direct inference to its impossibility. The empirical philosophy destroys itself, ending with Hume in skepticism and probabilism. Rationalism is overtaken by a different, and yet an analogous fate—it breaks up into a popular eclecticism. It believes that it has discovered an infallible criterion of truth in the clearness and distinctness of ideas, and a sure example for philosophical method in the method of mathematics. In both points it is wrong. The criterion of truth is insufficient, for Spinoza and Leibnitz built up their opposing theories—the pantheism of the one and the monadology of the other—from equally clear and distinct conceptions; tried by this standard individualism is just as true as pantheism. Mathematics, again, does not owe its unquestioned acceptance and cogent force to the clearness and distinctness of its conceptions, but to the fact that these are capable of construction in intuition. The distinction between mathematics and metaphysics was overlooked, namely, that mathematical thought can transform its conceptions into intuitions, can generate its objects or sensuously present them, which philosophical thought is not in a position to do. The objects of the latter must be given to it, and to the human mind they are given in no other way than through sensuous intuition. Metaphysics seeks to be a science of the real, but it is impossible to conjure being out of thought; reality cannot be proved from concepts, it can only be felt. In making the unperceivable and suprasensible (the real nature of things, the totality of the world, the Deity, and immortality) the special object of philosophy, rationalism looked on the understanding as a faculty of knowledge by which objects are given. In reality objects can never be given through concepts; these only render it possible to think objects given in some other way (by intuition). It is true that concepts of the suprasensible exist, but nothing can be known through them, there is nothing intuitively given to be subsumed under them.
