What is the amount of the arrest? As much as all the weaker representations together come to—the sum of arrest or the sum of that which becomes unconscious (as it were the burden to be divided) is equal to the sum of all the representations with the exception of the strongest (hence = b + c), and is divided among the individual representations in the inverse ratio of their strength, consequently in such a way that the strongest (the one which most actively and successfully resists arrest) has the least, and the weakest the most, of it to bear. It may thus come to pass that a representation is entirely driven out of consciousness by two stronger ones, while it is impossible for this to happen to it from a single one, no matter how superior it be. The simplest case of all is when two equally strong representations are present, in which case each is reduced to the half of its original intensity. The sum of that which remains in consciousness is always equal to the greatest representation.
[Footnote 1: By their mutual pressure representations are transformed into a mere tendency to represent, which again becomes actual representation when the arrest ceases. The parts of a representation transformed into a tendency, and the residua remaining unobscured, are not pieces cut off, but the quantity denotes merely a degree of obscuration in the whole representation, or rather in the representation which actually takes place.]
As soon as a representation reaches the zero point of consciousness, or as soon as a new representation (sensation) comes in, the others begin at once to rise or sink. The Mechanics seeks to investigate the laws of these movements of representations; but we may the more readily pass over its complicated calculations since their precise formulas can never more than very roughly represent the true state of the case, which simply rebels against precision. The rock on which every immanent use of mathematics in psychology must strike, is the impossibility of exactly measuring one representation by another. We may, indeed, declare one stronger than another on the basis of the immediate impression of feeling, but we cannot say how much stronger it is, nor with reason assert that it is twice or half as intense. Herbart's mathematical psychology was wrecked by this insurmountable difficulty. The demand for exactness which it raised, but which it was unable to satisfy with the means at its disposal, has recently been renewed, and has led to assured results in psycho-physics, which works on a different basis and with ingenious methods of measurement.
Herbart endeavors, as we have seen, to deduce the various mental activities from the play of representations, Feeling and desire are not something beside representations, are not special faculties of the soul, but results of the relations of representations, changing states of representations arrested and working upward against hindrances. A representation which has been forced out of consciousness persists as a tendency or effort to represent, and as such exerts a pressure on the conscious representations. If a representation is suspended between counteracting forces a feeling results; desire is the rise of a representation in the face of hindrances, aversion is hesitation in sinking. If the effort is accompanied by the idea that its goal is attainable, it is termed will. The character of a man depends on the fact that definite masses of representations have become dominant, and by their strength and persistence hold opposing representations in check or suppress them. The longer the dominant mass of representations exercises its power, the firmer becomes the habit of acting in a certain way, the more fixed the will. Herbart's intellectualistic denial of self-dependence to the practical capacities of the soul leads him logically to determinism. Volition depends on insight, is determined by representations; freedom signifies nothing but the fact that the will can be determined by motives. If the individual decisions of man were undetermined he would have no character; if the character were free in the choice between two actions, then, along with the noblest resolve, there would remain the possibility of an opposite decision; freedom of choice would make pure chance the doer of our deeds. Pedagogics, above all, must reject the idea of an undetermined freedom; education, along with imputation, correction, and punishment, would be a meaningless word, if no determining influence on the will of the pupil were possible.—This last objection overlooks the fact that the pedagogical influence is always mediate, and can do no more than, by disciplining the impulses of the pupil and by supplying him with aids against immoral inclinations, to lighten his moral task. We can work on the motives only, never directly on the will itself. Otherwise it would be inexplicable that even the best pedagogical skill proves powerless in the case of many individuals.
Herbart's psychology was preceded by a philosophy of nature, which construes matter from attraction and repulsion, and declares an actio in distans impossible. The intermediate link between physics and psychology is formed by the science of organic life (physiology or biology); and with this natural theology is connected by the following principles: The purposiveness which we notice with admiration in men and the higher animals compels us, since it can neither come from chance nor be explained on natural grounds alone, to assume as its author a supreme artificer, an intelligence which works by ends. It is true, indeed, that the existence of the Deity is not demonstrated by the teleological argument; this is only an hypothesis, but one as highly probable as the assumption that the human bodies by which we are surrounded are inhabited by human souls—a fact which we can only assume, not perceive nor prove. The assurance of faith is different from that of logic and experience, but not inferior to it. Religion is based on humility and grateful reverence, which is favored, not injured, by the immeasurable sublimity of its object, the incompleteness of our idea of the Supreme Being, and the knowledge of our ignorance. If faith rests, on the one hand, on the teleological view of nature, it is, on the other, connected with moral need, and exercises, in addition, aesthetic influences. By comforting the suffering, setting right the erring, reclaiming and pacifying the sinner, warning, strengthening, and encouraging the morally sound, religion brings the spirit into a new and better land, shows it a higher order of things, the order of providence, which, amid all the mistakes of men, still furthers the good. The religious spirit always includes an ethical element, and the bond of the Church holds men together even where the state is destroyed. Indispensable theoretically as a supplement to our knowledge, and practically because of the moral imperfection of men, who need it to humble, warn, comfort, and lift them up, religion is, nevertheless, in its origin independent of knowledge and moral will. Faith is older than science and morals: the doctrine of religion did not wait for astronomy and cosmology, nor the erection of temples for ethics. Before the development of the moral concepts religion already existed in the form of wonder without a special object, of a gloomy awe which ascribed every sudden inner excitement to the impulse of an invisible power. Since a speculative knowledge of the nature of God is impossible, the only task which remains for metaphysics is the removal of improper determinations from that which tradition and phantasy have to say on the subject. We are to conceive God as personal, extramundane, and omnipotent, as the creator, not of the reals themselves, but of their purposive coexistence (Zusammen). In order, however, to rise from the idea of the original, most real, and most powerful being to that of the most excellent being we need the practical Ideas, without which the former would remain an indifferent theoretical concept. Man can pray only to a wise, holy, perfect, just, and good God.
This, in essential outline, is the content of the scattered observations on the philosophy of religion given by Herbart. Drobisch (Fundamental Doctrines of the Philosophy of Religion, 1840), from the standpoint of religious criticism and with a renewal of the moral argument, and Taute (1840-52) and Flügel (Miracles and the Possibility of a Knowledge of God, 1869) with an apologetic tendency and one toward a belief in miracles, have, among others, endeavored to make up for the lack of a detailed treatment of this discipline by Herbart—from which, moreover, much of value could hardly have been expected in view of the jejuneness of his metaphysical conceptions and the insufficiency of his appreciation of evil.
It remains only to glance at Herbart's Aesthetics. The beautiful is distinguished from the agreeable and the desirable, which, like it, are the objects of preference and rejection, by the facts, first, that it arouses an involuntary and disinterested judgment of approval; and second, that it is a predicate which is ascribed to the object or is objective. To these is added, thirdly, that while desire seeks for that which is to come, taste possesses in the present that which it judges.
That which pleases or displeases is always the form, never the matter; and further, is always a relation, for that which is entirely simple is indifferent. As in music we have succeeded in discovering the simplest relations, which please immediately and absolutely—we know not why—so this must be attempted in all branches of the theory of art. The most important among them, that which treats of moral beauty, moral philosophy, has therefore to inquire concerning the simplest relations of will, which call forth moral approval or disapproval (independently of the interest of the spectator), to inquire concerning the practical Ideas or pattern-concepts, in accordance with which moral taste, involuntarily and with unconditional evidence, judges concerning the worth or unworth of (actually happening or merely represented) volitions. Herbart enumerates five such primary Ideas or fundamental judgments of conscience.
(1) The Idea of inner freedom compares the will with the judgment, the conviction, the conscience of the agent himself. The agreement of his desire with his own judgment, with the precept of his taste, pleases, lack of agreement displeases. Since the power to determine the will according to one's own insight of itself establishes only an empty consistency and loyalty to conviction, and may also subserve immoral craft, the first Idea waits for its content from the four following.
(2) The Idea of perfection has reference to the quantitative relations of the manifold strivings of a subject, in intensity, extension, and concentration. The strong is pleasing in contrast with the weak, the greater (more extended, richer) in contrast with the smaller, the collected in contrast with the scattered; in other words, in the individual desires it is energy which pleases, in their sum variety, in the system co-operation. While the first two Ideas have compared the will of the individual man with itself, the remaining ones consider its relation to the will of other rational beings, the third to a merely represented will, and the last two to an actual one.
