We call the given sensation-complexes "things," and ascribe "properties" to them. How can one and the same thing have different properties—how can the one be at the same time many? To say that the thing "possesses" the properties does not help the matter. The possession of the different properties is itself just as manifold and various as the properties which are possessed. Hence the concept of the thing and its properties must be so transformed that the plurality which seems to be in the thing shall be transferred without it. Instead of one thing let us assume several, each with a single definite property, from whose "together" the appearance of many qualities in one thing now arises. The appearance of manifold properties in the one thing has its ground in the "together" of many things, each of which has one simple quality. Again, it is just as impossible for a thing to have different qualities in succession, or to change, as it is for it to have them at the same time. The popular view of change, which holds that a thing takes on different forms (ice, water, steam) and yet remains the same substance, is untenable. How is it possible to become another, and yet to remain the same? The universal feeling that the concept needs correction betrays itself in the fact that everyone involuntarily adds a cause to the change in thought, and seeks a cause for it, and thus of himself undertakes a transformation of the concept, though, it is true, an inadequate one. If we think this concept through we come upon a trilemma, a threefold impossibility. Whether we endeavor to deduce the change from external or from internal causes, or (with Hegel) to think it as causeless, in each case we involve ourselves in inconceivabilities. All three ideas—change as mechanism, as self-determination or freedom, as absolute becoming—are alike absurd. We can escape these contradictions only by the bold decision to conceive the quality of the existent as unchangeable. For the truly existent there is no change whatever. It remains, however, to explain the appearance of change, in which the wand of decomposition and the "together" again proves its magic power. Supported by the motley manifoldness of phenomena, we posit real beings as qualitatively different, and view this diversity as partial contraposition; we resolve, e.g., the simple quality a into the elements x + z, and a second quality b into y - z. So long as the individual things remain by themselves, the opposition of the qualities will not make itself evident. But as soon as they come together, something takes place—now the opposites (+z and -z) seek to destroy or at least to disturb each other. The reals defend themselves against the disturbance which would follow if the opposites could destroy each other, by each conserving its simple, unchangeable quality, i.e., by simply remaining self-identical. Self-conservation against threatened disturbances from without (it may be compared to resistance against pressure) is the only real change, and apparent change, the empirical changes of things, to be explained from this. That which changes is only the relations between the beings, as a thing maintains itself now against this and now against that other thing; the relations, however, and their change are something entirely contingent and indifferent to the existent. In itself the self-conservation of a real is as uniform as the quality which is conserved, but in virtue of the changing relations (the variety of the disturbing things) it can express itself for the observer in manifold ways as force. The real itself changes as little as a painting changes, for instance, when, seen near at hand, the figures in it are clearly distinguished, while for the distant observer, on the contrary, they run together into an indistinguishable chaos. Change has no meaning in the sphere of the existent.

Anyone who speaks thus has denied change, not deduced it. Among the many objections experienced by Herbart's endeavor to explain the empirical fact of change by his theory of self-conservation against threatened disturbances Lotze's is the most cogent: The unsuccessful attempt to solve the difficulties in the concept of becoming and action is still instructive, for it shows that they cannot be solved in this way—from the concept of inflexible being. If the "together," the threatened disturbance, and the reaction against the latter be taken as realities, then, in the affection by the disturber, the concept of change remains uneliminated and uncorrected; if they be taken as unreal concepts auxiliary to thought, change is relegated from the realm of being to the realm of seeming. Herbart gives to them a kind of semi-reality, less true than the unmoving ground of things (their unchangeable, permanent qualities), and more true than their contradictory exterior (the empirical appearance of change). Between being and seeming he thrusts in, as though between day and night, the twilight region of his "contingent aspects," with their relations, which are nothing to the real, their disturbances, which do not come to pass, and their self-conservations, which are nothing but undisturbed continuance in existence on the part of the real.

Besides the contradictions in the concepts of inherence, of change, and action and passion, it is the concept of being which prevents our philosopher from ascribing a living character to reality. Being, as Kant correctly perceived, contains nothing qualitative; it is absolute position. Whoever affirms that an object is, expresses thereby that the matter is to rest with the simple position; in which is included that it is nothing dependent, relative, or negative. (Every negation is something relative, relates to a precedent position, which is to be annulled by it.) Besides being, the existent contains something more—a quality; it consists of this absolute position and a what. If this what is separated from being we reach an "image"; united with being it yields an essence or a real. This what of things is not their sensuous qualities; the latter belong rather to the mere phenomenon. No one of them indicates what the object is by itself, when left alone. They depend on contingent circumstances, and apart from these they would not exist—what is color in the dark? what sound in airless space? what weight in empty space? what fusibility without fire?—they are each and all relative. Since being excludes negation of every kind, the quality of the existent must be absolutely simple and unchangeable; it brooks no manifoldness, no quantity, no distinctions in degree, no becoming; all this were a corruption of the purely affirmative or positive character of being. The existent is unextended and eternal. The Eleatics are to be praised because the need of escaping from the contradictions in the world of experience led them to make themselves masters of the concept of being without relation and without negation, and of the simple, homogeneous quality of the existent in its full purity. But while the Eleatics conceived the existent as one, the atomists made an advance by assuming a plurality of reals. The truly one never becomes a plurality; plurality is given, hence an original plurality must be postulated. Herbart characterizes his own standpoint as qualitative atomism, since his reals are differentiated by their properties, not by quantitative relations (size and figure). The idealists and the pantheists make a false use of the tendency toward unity which, no doubt, is present in our reason, when they maintain that true being must be one. There is absolutely nothing in the concept of being to forbid us to think the existent as many; while the world of phenomena, with its many things and their many properties, gives irrefragable grounds which compel us to this conclusion. Hence, according to Herbart, the true reality is a (very large, though not, it is true, an infinite[1]) plurality of supra-sensible (non-spatial and non-temporal) reals, or, according to the Leibnitzian expression, monads, which all their life have nothing further to do than to preserve intact against disturbances the simple quality in which they consist (for the existent is not distinct from its quality; it does not have the quality, but is the quality). Each thing has but one response for the most varied influences: it answers all suggestions from without by affirming its what, by continually repeating, as it were, the same note, which gains a varying meaning only in so far as, in accordance with the character of the disturber, it appears now as a third, now as a fifth or seventh. This picture of the world is certainly not attractive; in it all change and becoming, all life and all activity is offered up on the altar of monotonous being. Happily Herbart is inconsistent enough to enliven this comfortless waste of changeless being by the relatively real or semi-real manifoldness of the self-conservations.

The infinite divisibility of space and of matter forms the chief difficulty in the problem of the continuous. Herbart endeavors to solve it by the assumption of an intelligible space with "fixed" lines (lines formed by a definite number of points, hence finitely divisible, and not continuous). Metaphysics demands the fixed or discrete line, although common thought is incapable of conceiving it. Space is a mere form of combination in representation or for the observer, and yet it is objective, i.e., it is valid for all intelligences, and not merely for human intelligence. From his complex and unproductive endeavors to derive the appearance of continuity from discontinuous reality we hurry on to the fourth, the psychological problem, which Herbart discusses with great acuteness. He considers it the chief merit of Fichte's Science of Knowledge that it called attention to this problem.

The concept of the ego, of whose reality we have so strong and immediate a conviction that, in the formula of asseveration, "as true as I exist," it is made the criterion of all other certitude, labors under various contradictions. Besides the familiar difficulty, here especially sensible, of one thing with many marks, it contains other absurdities of its own. In the ego or self-consciousness subject and object are to be identical. The identity of the representing and the represented ego is a self-contradictory idea, for the law of contradiction forbids the equation of opposites, while a subject is subject only through the fact that it is not object. But, again, self-consciousness can never be realized, because it involves a regressus in infinitum. The ego is defined as that which represents itself. What is this "self"? It is, in turn, the self-knower. This new explanation contains still a further self; which once more signifies the self-knower and so on to infinity. The ego represents the representation (Vorstellen) of its representation (Vorstellen), etc. The representation (Vorstellung) of the ego, therefore, can never be actually brought to completion. (The assumption of the freedom of the will leads to an analogous regressus in infinitum, in which the question, "Willst thou thy volition?" "Willst thou the willing of this volition"? is repeated to infinity.) The only escape from this tissue of absurdities is to think the ego otherwise than is done by popular consciousness. The knowing and the known ego are by no means the same, but the observing subject in self-consciousness is one group of representations, the observed subject another. Thus, for example, newly formed representations are apperceived by the existing older ones, but the highest apperceiver is not, in turn, itself apperceived. The ego is not a unit being, which represents itself in the literal meaning of the phrase, but that which is represented is a plurality. The ego is the junction of numberless series of representations, and is constantly changing its place; it dwells now in this representation, now in that. But as we distinguish the point of meeting from the series which meet there, and imagine that it is possible simultaneously to abstract from all the represented series (whereas in fact we can only abstract from each one separately), there arises the appearance of a permanent ego as the unit subject of all our representations. In reality the ego is not the source of our representations, but the final result of their combination. The representation, not the ego, is the fundamental concept of psychology, the ego constituting rather its most difficult problem.[1] It is a "result of other representations, which, however, in order to yield this result, must be together in a single substance, and must interpenetrate one another" (Text-book of Introduction, p. 243). In this way Herbart defends the substantiality of the soul against Kant and Fries. The soul's immortality (as also its pre-existence) goes without saying, because of the non-temporal character of the real.

The soul is one of these reals which, unchangeable in themselves, enter into various relations with others, and conserve themselves against the latter. In its simple what as unknowable as the rest, it is yet familiar to us in its self-conservations. In the absence of a more fitting expression for the totality of psychical phenomena we call these representations, the phenomenal manifoldness of which is due to the variety of the disturbances and exists for the observer alone. In itself, without a plurality of dispositions and impulses, the soul is originally not a representative force, but first becomes such under certain circumstances, viz., when it is stimulated to self-conservation by other beings. The sum of the reals which stand in immediate relation to the soul is called its body; this, an aggregate of simple beings, furnishes the intermediate link of causal relation between the soul and the external world. The soul has its (movable) seat in the brain. In opposition to the physiological treatment of psychology, Herbart remarks that psychology throws much more light on physiology than she can ever receive from it.

The simplest representations are the sensations, which, amid all their variety, still group themselves into definite classes (odors, sounds, colors). They serve us as symbols of the disturbing reals, but they are not images of things, nor effects of these, but products of the soul itself: the generation of sensations is the soul's peculiar way of guarding itself against threatened disturbances. Every representation once come into being disappears again from consciousness, it is true, but not from the soul. It persists, unites with others, and stands with them in a relation of interaction—in both cases according to definite laws. These original representations are the only ones which the soul produces by its own activity; all other psychical phenomena, feeling, desire, will, attention, memory, judgment, the whole wealth of inner events, result of themselves from the interplay of the primary representations under law. Representation (more exactly sensation) is alone original; space, time, the categories, which Kant makes a priori, are all acquired, i.e., like all the higher mental life, they are the results of a psychical mechanism, results whose production needs no renewed exertion on the part of the soul itself. It has been a very harmful error in psychology hitherto to ascribe each particular mental activity to a special faculty of the soul having a similar name, instead of deriving it from combinations of simple representations. Abstract, empty class ideas have been treated as real forces, in the belief that thus the single concrete acts had been "explained."

There is no bitterer foe of the faculty theory than Herbart. His campaign against it, if not victorious, was yet salutary, and the motives of his hostility, up to a certain point, entirely justified. Nothing is more useless than the assurance that what the soul actually does, that it must also have the power to do. Who disputes this? A faculty explains nothing so long as the laws under which its functions and its relations to other faculties remain unexplained. But although the faculty idea serves no positive end, it cannot be entirely discarded. It marks the boundary where our ability to reduce one class of psychical phenomena to another ceases. Herbart's polemic has no force against the moderate and necessary use of this idea, no matter how much it was in place in view of the impropriety of a superfluous multiplication of the faculties of the soul. The realization of the ideal of psychology, the reduction of the complex phenomena of mental life to the smallest possible number of simple elements, is limited by the heterogeneity of the original phenomena, knowing, feeling, willing, which wholly resists derivation from the combination of sensations. That which blinded Herbart to these limitations was that tendency toward unity, which, as a metaphysician and moral philosopher, he had all too willfully suppressed, and which now took revenge for this infringement of its rights by misleading the psychologist to an exaggeration which had important consequences. Nevertheless his unsuccessful attempt remains interesting and worthy of gratitude.

The discovery of the laws which govern the interaction of the psychical elements is the task of a statics and a mechanics of representations. The former investigates the equilibrium or the settled final state; the latter, the change, i.e. the movements of representations. These names of themselves betray Herbart's conviction that mathematics can and must be applied to psychology. The bright hopes, however, which Herbart formed for the attempt at a mathematical psychology, were fulfilled neither in his own endeavors nor in those of his pupils, although, as Lotze remarks, it would be asserting too much to say that the most general formulas which he set up contradict experience.—The unity of the soul forces representations to act on one another. Disparate representations, those, that is, which belong to different representative series, as the visual image of a rose and the auditory image of the word rose, or as the sensations yellow, hard, round, ringing, connected in the concept gold piece, enter into complications [complexes]. Homogeneous representations (the memory image and the perceptual image of a black poodle) fuse into a single representation. Opposed representations (red and blue) arrest one another when they are in consciousness together. The connection and graded fusion of representations is the basis of their retention and reproduction, as well as of the formation of continuous series of representations. The reproduction is in part immediate, a free rising of the representation by its own power as soon as the hindrances give way; in part mediate, a coming up through the help of others. On the arrest of partially or totally opposed representations Herbart bases his psychological calculus. Let there be given simultaneously in consciousness three opposed representations of different intensities, the strongest to be called a, the weakest c, the intermediate one b. What happens? They arrest one another, i.e. a part of each is forced to sink below the threshold of consciousness.[1]
