Essay II. Aims And Methods Of Psychology.
At an early period Herbart had become impressed with the necessity of applying mathematics to psychology(29). To the usual objection, that psychical facts do not admit of measurement, he had a ready reply. We can calculate even on hypothetical assumptions: indeed, could we measure, we should scarcely take the trouble to calculate(30). To calculate (i.e. to deduce mathematically) is to perform a general experiment, and to perform it in the medium where there is least likelihood of error or disturbance. There may be anomalies enough apparent in the mental life: there may be the great anomalies of Genius and of Freedom of Will; but the Newton and the Kepler of psychology will show by calculation on assumed conditions of psychic nature that these aberrations can be explained by mechanical laws. “The human Soul is no puppet-theatre: our wishes and resolutions are no marionettes: no juggler stands behind; but our true and proper life lies in our volition, and this life has its rule not outside, but in itself: it has its own purely mental rule, by no means borrowed from the material world. But this rule is in it sure and fixed; and on account of this its fixed quality it has more similarity to (what is otherwise heterogeneous) the laws of impact and pressure than to the marvels of an alleged inexplicable freedom(31).”
Psychology then deals with a real, which exhibits phenomena analogous in several respects to those discussed by statics and mechanics. Its foundation is a statics and mechanics of the Soul,—as this real is called. We begin by presupposing as the ultimate reality, underlying the factitious and generally imperfect unity of self-consciousness and mind, an essential and primary unity—the unity of an absolutely simple or individual point of being—a real point which amongst other points asserts itself, maintains itself. It has a character of its own, but that character it only shows in and through a development conditioned by external influences. The specific nature of the soul-reality is to be representative, to produce, or manifest itself in, ideas (_Vorstellungen_). But the character only emerges into actuality in the conflict of the soul-atom with other ultimate realities in the congregation of things. A soul _per se_ or isolated is not possessed of ideas. It is merely blank, undeveloped, formal unity, of which nothing can be said. But like other realities it defines and characterises itself by antithesis, by resistance: it shows what it is by its behaviour in the struggle for existence. It acts in self-defence: and its peculiar style or weapon of self-defence is an idea or representation.
The way the Soul maintains itself is by turning the assailant into an idea(32): and each idea is therefore a _Selbsterhaltung_ of the Soul. The Soul is thus enriched—to appearance or incidentally: and the assailant is annexed. In this way the one Soul may develop or evolve or express an innumerable variety of ideas: for in response to whatever it meets, the living and active Soul ideates, or gives rise to a representation. Thus, while the soul is one, its ideas or representations are many. Taken separately, they each express the psychic self-conservation. But brought in relation with each other, as so many acts or self-affirmations of the one soul, they behave as forces, and tend to thwart or check each other. It is as forces, as reciprocally arresting or fostering each other, that ideas are objects of science. When a representation is thus held in check, it is reduced to a mere endeavour or active tendency to represent. Thus there arises a distinction between representations proper, and those imperfect states or acts which are partly or wholly held in abeyance. But the latent phase of an idea is as essential to a thorough understanding of it as what appears. It is the great blunder of empirical psychology to ignore what is sunk below the surface of consciousness. And to Herbart consciousness is not the condition but rather the product of ideas, which are primarily forces.
But representations are not merely in opposition,—impinging and resisting. The same reason which makes them resist, viz. that they are or would fain be acts of the one soul, but are more or less incompatible, leads them in other circumstances to form combinations with each other. These combinations are of two sorts. They are, first, complications, or “complexions”: a number of ideas combine by quasi-addition and juxtaposition to form a total. Second, there is fusion: ideas presenting certain degrees of contrast enter into a union where the parts are no longer separately perceptible. It is easy to see how the problems of psychology now assume the form of a statics and mechanics of the mind. Quantitative data are to be sought in the strength of each separate single idea, and the degree in which two or more ideas block each other: in the degree of combination between ideas, and the number of ideas in a combination: and in the terms of relation between the members of a series of ideas. A statical theory has to show the conditions required for what we may call the ideal state of equilibrium of the “idea-forces”: to determine, that is, the ultimate degree of obscuration suffered by any two ideas of different strength, and the conditions of their permanent combination or fusion. A mechanics of the mind will, on the contrary, deal with the rate at which these processes are brought about, the velocity with which in the movement of mind ideas are obscured or reawakened, &c.
It is fortunately unnecessary, here, to go further into details. What Herbart proposes is not a method for the mathematical measurement of psychic facts: it is a theory of mechanics and statics specially adapted to the peculiarities of psychical phenomena, where the forces are given with no sine or cosine, where instead of gravitation we have the constant effort (as it were elasticity) of each idea to revert to its unchecked state. He claims—in short—practically to be a Kepler and Newton of the mind, and in so doing to justify the vague professions of more than one writer on mind—above all, perhaps of David Hume, who goes beyond mere professions—to make mental science follow the example of physics. And a main argument in favour of his enterprise is the declaration of Kant that no body of knowledge can claim to be a science except in such proportion as it is mathematical. And the peculiarity of this enterprise is that self-consciousness, the Ego, is not allowed to interfere with the free play of psychic forces. The Ego is—psychologically—the result, the product, and the varying product of that play. The play of forces is no doubt a unity: but its unity lies not in the synthesis of consciousness, but in the essential unity of Soul. And Soul is in its essence neither consciousness, nor self-consciousness, nor mind: but something on the basis of whose unity these are built up and developed(33). The mere “representation” does not include the further supervenience of consciousness: it represents, but it is not as yet necessary that we should also be conscious that there is representation. It is, in the phrase of Leibniz, perception: but not apperception. It is mere straight-out, not as yet reflected, representation. Gradually there emerges through the operation of mechanical psychics a nucleus, a floating unity, a fixed or definite central aggregate.
The suggestion of mathematical method has been taken up by subsequent inquirers (as it was pursued even before Herbart’s time), but not in the sense he meant. Experimentation has now taken a prominent place in psychology. But in proportion as it has done so, psychology has lost its native character, and thrown itself into the arms of physiology. What Herbart calculated were actions and reactions of idea-forces: what the modern experimental school proposes to measure are to a large extent the velocities of certain physiological processes, the numerical specification of certain facts. Such ascertainments are unquestionably useful; as numerical precision is in other departments. But, taken in themselves, they do not carry us one bit further on the way to science. As experiments, further,—to note a point discussed elsewhere(34)—their value depends on the point of view, on the theory which has led to them, on the value of the general scheme for which they are intended to provide a special new determination. In many cases they serve to give a vivid reality to what was veiled under a general phrase. The truth looks so much more real when it is put in figures: as the size of a huge tree when set against a rock; or as when Milton bodies out his fallen angel by setting forth the ratio between his spear and the tallest Norway pine. But until the general relationship between soul and body is more clearly formulated, such statistics will have but a value of curiosity.
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 said(36) 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 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 “desires(37)”—leads on cumulatively to Will, which is the “last appetite in deliberating.” Spinoza, his contemporary, speaks in the same strain(38). “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 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 panel(39),” 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 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. 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’s(41). 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 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.
It is partly a desire of keeping up to date which is responsible for the copious extracts or abstracts from treatises on the anatomy and functions of the nerve-system, which, accompanied perhaps by a diagram of the brain, often form the opening chapter of a work on psychology. Even if these researches had achieved a larger number of authenticated results than they as yet have, they would only form an appendix and an illustration to the proper subject(42). As they stand, and so long as they remain largely hypothetical, the use of them in psychology only fosters the common delusion that, when we can picture out in material outlines a theory otherwise unsupported, it has gained some further witness in its favour. It is quite arguable indeed that it may be useful to cut out a section from general human biology which should include the parts of it that were specially interesting in connexion with the expression or generation of thought, emotion, and desire. But in that case, there is a blunder in singling out the brain alone, and especially the organs of sense and voluntary motion,—except for the reason that this province of psycho-physics alone has been fairly mapped out. The preponderant half of the soul’s life is linked to other parts of the physical system. Emotion and volition, and the general tone of the train of ideas, if they are to be connected with their expression and physical accompaniment (or aspect), would require a sketch of the heart and lungs, as well as the digestive system in general. Nor these alone. Nerve analysis (especially confined to the larger system), though most modern, is not alone important, as Plato and Aristotle well saw. So that if biology is to be adapted for psychological use (and if psychology deals with more than cognitive processes), a liberal amount of physiological information seems required.
Experimental psychology is a term used with a considerable laxity of content; and so too is that of physiological psychology, or psycho-physics. And the laxity mainly arises because there is an uncertainty as to what is principal and what secondary in the inquiry. Experiment is obviously a help to observation: and so far as the latter is practicable, the former would seem to have a chance of introduction. But in any case, experiment is only a means to an end and only practicable under the guidance of hypothesis and theory. Its main value would be in case the sphere of psychology were completely paralleled with one province of physiology. It was long ago maintained by Spinoza and (in a way by) Leibniz, that there is no mental phenomenon without its bodily equivalent, pendant, or correspondent. The _ordo rerum_ (the molecular system of movements) is, he held, the same as the order of ideas. But it is only at intervals, under special conditions, or when they reach a certain magnitude, that ideas emerge into full consciousness. As consciousness presents them, they are often discontinuous, and abrupt: and they do not always carry with them their own explanation. Hence if we are confined to the larger phenomena of consciousness alone, our science is imperfect: many things seem anomalous; above all, perhaps, will, attention, and the like. We have seen how Herbart (partly following the hints of Leibniz), attempted to get over this difficulty by the hypothesis of idea-forces which generate the forms and matter of consciousness by their mutual impact and resistance. Physiological psychology substitutes for Herbart’s reals and his idea-forces a more materialistic sort of reality; perhaps functions of nerve-cells, or other analogous entities. There, it hopes one day to discover the underlying continuity of event which in the upper range of consciousness is often obscured, and then the process would be, as the phrase goes, explained: we should be able to picture it out without a gap.
These large hopes may have a certain fulfilment. They may lead to the withdrawal of some of the fictitious mental processes which are still described in works of psychology. But on the whole they can only have a negative and auxiliary value. The value, that is, of helping to confute feigned connexions and to suggest truer. They will be valid against the mode of thought which, when Psyché fails us for an explanation, turns to body, and interpolates soul between the states of body: the mode which, in an older phraseology, jumps from final causes to physical, and from physical (or efficient) to final. Here, as elsewhere, the physical has its place: and here, more than in many places, the physical has been unfairly treated. But the whole subject requires a discussion of the so-called “relations” of soul and body: a subject on which popular conceptions and so-called science are radically obscure.
“But the danger which threatens experimental psychology,” says Münsterberg, “is that, in investigating details, the connexion with questions of principle may be so lost sight of that the investigation finally lands at objects scientifically quite worthless(43). Psychology forgets only too easily that all those numerical statistics which experiment allows us to form are only means for psychological analysis and interpretation, not ends in themselves. It piles up numbers and numbers, and fails to ask whether the results so formed have any theoretical value whatever: it seeks answers before a question has been clearly and distinctly framed; whereas the value of experimental answers always depends on the exactitude with which the question is put. Let me remind the reader, how one inquirer after another made many thousand experiments on the estimation of small intervals of time, without a single one of them raising the question what the precise point was which these experiments sought to measure, what was the psychological occurrence in the case, or what psychological phenomena were employed as the standard of time-intervals. And so each had his own arbitrary standard of measurement, each of them piled up mountains of numbers, each demonstrated that his predecessor was wrong; but neither Estel nor Mehner have carried the problem of the time-sense a single step further.
