What Herbart (as well as Hegel) finds perpetual ground for objecting to is the talk about mental faculties. This objection is part of a general characteristic of all the higher philosophy; and the recurrence of it gives an illustration of how hard it is for any class of men to see themselves as others see them. If there be anything the vulgar believe to be true of philosophy, it is that it deals in distant and abstruse generalities, that it neglects the shades of individuality and reality, and launches out into unsubstantial general ideas. But it would be easy to gather from the great thinkers an anthology of passages in which they hold it forth as the great work of philosophy to rescue our conceptions from the indefiniteness and generality of popular conception, and to give them real, as opposed to a merely nominal, individuality.

The Wolffian school, which Herbart (not less than Kant) found in possession of the field, and which in Germany may be taken to represent only a slight variant of the half-and-half attitude of vulgar thought, [pg lxxiv] was entrenched in the psychology of faculties. Empirical psychology, said Wolff35, tells the number and character of the soul's faculties: rational psychology will tell what they “properly” are, and how they subsist in soul. It is assumed that there are general receptacles or tendencies of mental operation which in course of time get filled or qualified in a certain way: and that when this question is disposed of, it still remains to fix on the metaphysical bases of these facts.

That a doctrine of faculties should fix itself in psychology is not so wonderful. In the non-psychical world objects are easily discriminated in space, and the individual thing lasts through a time. But a phase of mind is as such fleeting and indeterminate: its individual features which come from its “object” tend soon to vanish in memory: all freshness of definite characters wears off, and there is left behind only a vague “recept” of the one and same in many, a sort of hypostatised representative, faint but persistent, of what in experience was an ever-varying succession. We generalise here as elsewhere: but elsewhere the many singulars remain to confront us more effectually. But in Mind the immense variety of real imagination, memory, judgment is forgotten, and the name in each case reduced to a meagre abstract. Thus the identity in character and operation, having been cut off from the changing elements in its real action, is transmuted into a substantial somewhat, a subsistent faculty. The relationship of one to another of the powers thus by abstraction and fancy created becomes a problem of considerable moment, their causal relations in particular: till in the end they stand outside and independent of each other, engaged, as Herbart says, in a veritable bellum omnium contra omnes.

But this hypostatising of faculties becomes a source of still further difficulties when it is taken in connexion with the hypostasis of the Soul or Self or Ego. To Aristotle the Soul in its general aspect is Energy or Essence; and its individual phases are energies. But in the hands of the untrained these conceptions came to be considerably displaced. Essence or Substance came to be understood (as may be seen in Locke, and still more in loose talk) as a something—a substratum—or peculiar nature—(of which in itself nothing further could be said36 but which notwithstanding was permanent and perhaps imperishable): this something subsistent exhibited certain properties or activities. There thus arose, on one hand, the Soul-thing—a substance misunderstood and sensualised with a supernatural sensuousness—a denizen of the transcendental or even of the transcendent world: and, on the other hand, stood the actual manifestations, the several exhibitions of this force, the assignable and describable psychic facts. We are accordingly brought before the problem of how this one substance or essence stands to the several entities or hypostases known as faculties. And we still have in the rear the further problem of how these abstract entities stand to the real and concrete single acts and states of soul and mind.

This hypostatising of faculties, and this distinction of the “Substantial” soul from its “accidentia” or phenomena, had grown—through the materialistic proclivities of popular conception—from the indications found in Aristotle. It attained its climax, perhaps in the Wolffian school in Germany, but it has been the resort of superficial psychology in all ages. For while it, on one hand, seemed to save the substantial Soul on whose incorruptibility great issues were believed to [pg lxxvi] hinge, it held out, on the other, an open hand to the experimental inquirer, whom it bade freely to search amongst the phenomena. But if it was the refuge of pusillanimity, it was also the perpetual object of censure from all the greater and bolder spirits. Thus, the psychology of Hobbes may be hasty and crude, but it is at least animated by a belief that the mental life is continuous, and not cut off by abrupt divisions severing the mental faculties. The “image” (according to his materialistically coloured psychology) which, when it is a strong motion, is called sense, passes, as it becomes weaker or decays, into imagination, and gives rise, by its various complications and associations with others, to reminiscence, experience, expectation. Similarly, the voluntary motion which is an effect or a phase of imagination, beginning at first in small motions—called by themselves “endeavours,” and in relation to their cause “appetites” or “desires37”—leads on cumulatively to Will, which is the “last appetite in deliberating.” Spinoza, his contemporary, speaks in the same strain38. “Faculties of intellect, desire, love, &c., are either utterly fictitious, or nothing but metaphysical entities, or universals which we are in the habit of forming from particulars. Will and intellect are thus supposed to stand to this or that idea, this or that volition, in the same way as stoniness to this or that stone, or as man to Peter or Paul.” They are supposed to be a general something which gets defined and detached. But, in the mind, or in the cogitant soul, there are no such things. There are only ideas: and [pg lxxvii] by an “idea” we are to understand not an image on the retina or in the brain, not a “dumb something, like a painting on a panel39,” but a mode of thinking, or even the act of intellection itself. The ideas are the mind: mind does not have ideas. Further, every “idea,” as such, “involves affirmation or negation,”—is not an image, but an act of judgment—contains, as we should say, an implicit reference to actuality—a reference which in volition is made explicit. Thus (concludes the corollary of Eth. ii. 49) “Will and Intellect are one and the same.” But in any case the “faculties” as such are no better than entia rationis (i.e. auxiliary modes of representing facts).

Leibniz speaks no less distinctly and sanely in this direction. “True powers are never mere possibilities: they are always tendency and action.” The “Monad”—that is the quasi-intelligent unit of existence—is essentially activity, and its actions are perceptions and appetitions, i.e. tendencies to pass from one perceptive state or act to another. It is out of the variety, the complication, and relations of these miniature or little perceptions and appetitions, that the conspicuous phenomena of consciousness are to be explained, and not by supposing them due to one or other faculty. The soul is a unity, a self-developing unity, a unity which at each stage of its existence shows itself in a perception or idea—each such perception however being, to repeat the oft quoted phrase, plein de l'avenir et chargé du passé:—each, in other words, is not stationary, but active and urgent, a progressive force, as well as a representative element. Above all, Leibniz has the view that the soul gives rise to all its ideas from itself: that its life is its own production, not a mere inheritance of ideas which it has from birth and nature, nor [pg lxxviii] a mere importation into an empty room from without, but a necessary result of its own constitution acting in necessary (predetermined) reciprocity and harmony with the rest of the universe.

But Hobbes, Spinoza, and Leibniz, were most attentively heard in the passages where they favoured or combatted the dominant social and theological prepossessions. Their glimpses of truer insight and even their palpable contributions in the line of a true psychology were ignored or forgotten. More attention, perhaps, was attracted by an attempt of a very different style. This was the system of Condillac, who, as Hegel says (p. 61), made an unmistakable attempt to show the necessary interconnexion of the several modes of mental activity. In his Traité des Sensations (1754), following on his Essai sur l'origine des connaissances humaines (1746), he tried to carry out systematically the deduction or derivation of all our ideas from sense, or to trace the filiation of all our faculties from sensation. Given a mind with no other power than sensibility, the problem is to show how it acquires all its other faculties. Let us then suppose a sentient animal to which is offered a single sensation, or one sensation standing out above the others. In such circumstances the sensation “becomes” (devient) attention: or a sensation “is” (est) attention, either because it is alone, or because it is more lively than all the rest. Again: before such a being, let us set two sensations: to perceive or feel (apercevoir ou sentir) the two sensations is the same thing (c'est la même chose). If one of the sensations is not present, but a sensation made already, then to perceive it is memory. Memory, then, is only “transformed sensation” (sensation transformée). Further, suppose we attend to both ideas, this is “the same thing” as to compare them. [pg lxxix] And to compare them we must see difference or resemblance. This is judgment. “Thus sensation becomes successively attention, comparison, judgment.” And—by further steps of the equating process—it appears that sensation again “becomes” an act of reflection. And the same may be said of imagination and reasoning: all are transformed sensations.

If this is so with the intelligence, it is equally the case with the Will. To feel and not feel well or ill is impossible. Coupling then this feeling of pleasure or pain with the sensation and its transformations, we get the series of phases ranging from desire, to passion, hope, will. “Desire is only the action of the same faculties as are attributed to the understanding.” A lively desire is a passion: a desire, accompanied with a belief that nothing stands in its way, is a volition. But combine these affective with the intellectual processes already noticed, and you have thinking (penser)40. Thus thought in its entirety is, only and always, transformed sensation.

Something not unlike this, though scarcely so simply and directly doctrinaire, is familiar to us in some English psychology, notably James Mill's41. Taken in their literal baldness, these identifications may sound strained—or trifling. But if we look beyond the words, we can detect a genuine instinct for maintaining and displaying the unity and continuity of mental life through all its modifications—coupled unfortunately with a bias sometimes in favour of reducing higher or more complex states of mind to a mere prolongation [pg lxxx] of lower and beggarly rudiments. But otherwise such analyses are useful as aids against the tendency of inert thought to take every name in this department as a distinguishable reality: the tendency to part will from thought—ideas from emotion—and even imagination from reason, as if either could be what it professed without the other.
