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.
[pg lxxv]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.
The difficulties of modern psychology perhaps lie in other directions, but they are not less worth guarding against. They proceed mainly from failure or inability to grasp the central problem of psychology, and a disposition to let the pen (if it be a book on the subject) wander freely through the almost illimitable range of instance, illustration, and application. Though it is true that the proper study of mankind is man, it is hardly possible to say what might not be brought under this head. Homo sum, nihil a me alienum puto, it might be urged. Placed in a sort of middle ground between physiology (summing up all the results of physical science) and general history (including the contributions of all the branches of sociology), the psychologist need not want for material. He can wander into ethics, aesthetic, and logic, into epistemology and metaphysics. And it cannot be said with any conviction that he is actually trespassing, so long as the ground remains so ill-fenced and vaguely enclosed. A desultory collection of observations on traits of character, anecdotes of mental events, mixed up with hypothetical descriptions of how a normal human being may be supposed [pg lxxxi] to develop his so-called faculties, and including some dictionary-like verbal distinctions, may make a not uninteresting and possibly bulky work entitled Psychology.
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 subject42. 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 [pg lxxxii] 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 [pg lxxxiii] 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 worthless43. Psychology [pg lxxxiv] 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.
“This must be all changed, if we are not to drift into the barrenest scholastic.... Everywhere out of the correct perception that problems of principle demand the investigation of detailed phenomena, and that the latter investigation must proceed in comparative independence of the question of principles, there has grown the false belief that the description of detail phenomena is the ultimate aim of science. And so, side by side with details which are of importance to principles, we have others, utterly indifferent and theoretically worthless, treated with the same zeal. To the solution of their barren problems the old Schoolmen applied a certain acuteness; but in order to turn out [pg lxxxv] masses of numbers from barren experiments, all that is needed is a certain insensibility to fits of ennui. Let numbers be less collected for their own sake: and instead, let the problems be so brought to a point that the answers may possess the character of principles. Let each experiment be founded on far more theoretical considerations, then the number of the experiments may be largely diminished44.”
What is thus said of a special group of inquiries by one of the foremost of the younger psychologists, is not without its bearings on all the departments in which psychology can learn. For physiological, or what is technically called psychological, experiment, is co-ordinate with many other sources of information. Much, for instance, is to be learnt by a careful study of language by those who combine sound linguistic knowledge with psychological training. It is in language, spoken and written, that we find at once the great instrument and the great document of the distinctively human progress from a mere Psyche to a mature Nous, from Soul to Mind. Whether we look at the varieties of its structure under different ethnological influences, or at the stages of its growth in a nation and an individual, we get light from language on the differentiation and consolidation of ideas. But here again it is easy to lose oneself in the world of etymology, or to be carried away into the enticing questions of real and ideal philology.
“The human being of the psychologist,” says Herbart45, “is the social and civilised human being who stands on the apex of the whole history through which his race has passed. In him is found visibly together all the multiplicity of elements, which, under the name of [pg lxxxvi] mental faculties, are regarded as a universal inheritance of humanity. Whether they are originally in conjunction, whether they are originally a multiplicity, is a point on which the facts are silent. The savage and the new-born child give us far less occasion to admire the range of their mind than do the nobler animals. But the psychologists get out of this difficulty by the unwarranted assumption that all the higher mental activities exist potentially in children and savages—though not in the animals—as a rudimentary predisposition or psychical endowment. Of such a nascent intellect, a nascent reason, and nascent moral sense, they find recognisable traces in the scanty similarities which the behaviour of child or savage offers to those of civilised man. We cannot fail to note that in their descriptions they have before them a special state of man, and one which, far from accurately defined, merely follows the general impression made upon us by those beings we name civilised. An extremely fluctuating character inevitably marks this total impression. For there are no general facts:—the genuine psychological documents lie in the momentary states of individuals: and there is an immeasurably long way from these to the height of the universal concept of man in general.”
And yet Man in general,—Man as man and therefore as mind—the concept of Man—normal and ideal man—the complete and adequate Idea of man—is the true terminus of the psychological process; and whatever be the difficulties in the way, it is the only proper goal of the science. Only it has to be built up, constructed, evolved, developed,—and not assumed as a datum of popular imagination. We want a concept, concrete and real, of Man and of Mind, which shall give its proper place to each of the elements that, in the several examples open to detailed observation, are presented [pg lxxxvii] with unfair or exaggerated prominence. The savage and the child are not to be left out as free from contributing to form the ideal: virtues here are not more important than vices, and are certainly not likely to be so informing: even the insane and the idiot show us what human intelligence is and requires: and the animals are also within the sweep of psychology. Man is not its theatre to the exclusion of woman; if it records the results of introspection of the Me, it will find vast and copious quarries in the various modes in which an individual identifies himself with others as We. And even the social and civilised man gets his designation, as usual, a potiori. He is more civilised and social than others: perhaps rather more civilised than not. But always, in some measure, he is at the same time unsocial or anti-social, and uncivilised. Each unit in the society of civilisation has to the outside observer—and sometimes even to his own self-detached and impartial survey—a certain oddity or fixity, a gleam of irrationality, which shows him to fall short of complete sanity or limpid and mobile intelligence. He has not wholly put off the savage,—least of all, says the cynic, in his relations with the other sex. He carries with him even to the grave some grains of the recklessness and petulance of childhood. And rarely, if ever, can it be said of him that he has completely let the ape and tiger die.
But that is only one way of looking at the matter—and one which, perhaps, is more becoming to the pathologist and the cynic, than to the psychologist. Each of these stages of psychical development, even if that development be obviously describable as degeneration, has something which, duly adjusted, has its place and function in the theory of the normally-complete human mind. The animal, the savage, and [pg lxxxviii] the child,—each has its part there. It is a mutilated, one-sided and superficial advance in socialisation which cuts off the civilised creature from the natural stem of his ancestry, from the large freedom, the immense insouciance, the childlikeness of his first estate. There is something, again, wanting in the man who utterly lacks the individualising realism and tenderness of the woman, as in the woman who can show no comprehension of view or bravery of enterprise. Even pathological states of mind are not mere anomalies and mere degenerations. Nature perhaps knows no proper degenerations, but only by-ways and intricacies in the course of development. Still less is the vast enormity or irregularity of genius to be ignored. It is all—to the philosophic mind—a question of degree and proportion,—though often the proportion seems to exceed the scale of our customary denominators. If an element is latent or quiescent (in arrest), that is no index to its absolute amount: “we know not what's resisted.” Let us by all means keep proudly to our happy mediocrity of faculty, and step clear of insanity or idiotcy on one hand, and from genius or heroism on the other. But the careful observer will notwithstanding note how delicately graded and how intricately combined are the steps which connect extremes so terribly disparate. It is only vulgar ignorance which turns away in hostility or contempt from the imbecile and the deranged, and only a worse than vulgar sciolism which sees in genius and the hero nothing but an aberration from its much-prized average. Criminalistic anthropology, or the psychology of the criminal, may have indulged in much frantic exaggeration as to the doom which nature and heredity have pronounced over the fruit of the womb even before it entered the shores of light: yet they have at least [pg lxxxix] served to discredit the free and easy assumption of the abstract averagist, and shown how little the penalties of an unbending law meet the requirements of social well-being.
Yet, if psychology be willing to learn in all these and other provinces of the estate of man, it must remember that, once it goes beyond the narrow range in which the interpretations of symbol and expression have become familiar, it is constantly liable to blunder in the inevitable effort to translate observation into theory. The happy mean between making too much of palpable differences and hurrying on to a similar rendering of similar signs is the rarest of gifts. Or, perhaps, it were truer to say it is the latest and most hardly won of acquirements. To learn to observe—observe with mind—is not a small thing. There are rules for it—both rules of general scope and, above all, rules in each special department. But like all “major premisses” in practice, everything depends on the power of judgment, the tact, the skill, the “gift” of applying them. They work not as mere rules to be conned by rote, but as principles assimilated into constituents of the mental life-blood: rules which serve only as condensed reminders and hints of habits of thought and methods of research which have grown up in action and reflection. To observe we must comprehend: yet we can only comprehend by observing. We all know how unintelligible—save for epochs of ampler reciprocity, and it may be even of acquired unity of interest—the two sexes are for each other. Parents can remember how mysteriously minded they found their own elders; and in most cases they have to experience the depth of the gulf which in certain directions parts them from their children's hearts. Even in civilised Europe, the ordinary member of each nation has an underlying [pg xc] conviction (which at moments of passion or surprise will rise and find harsh utterance) that the foreigner is queer, irrational, and absurd. If the foreigner, further, be so far removed as a Chinaman (or an Australian “black”), there is hardly anything too vile, meaningless, or inhuman which the European will not readily believe in the case of one who, it may be, in turn describes him as a “foreign devil.” It can only be in a fit of noble chivalry that the British rank and file can so far temporise with its insular prejudice as to admit of “Fuzzy-wuzzy” that
Not every one is an observer who chooses to dub himself so, nor is it in a short lapse of time and with condescension for foreign habits, that any observer whatever can become a trustworthy reporter of the ideas some barbarian tribe holds concerning the things of earth and air, and the hidden things of spirits and gods. The “interviewer” no doubt is a useful being when it is necessary to find “copy,” or when sharp-drawn characters and picturesque incidents are needed to stimulate an inert public, ever open to be interested in some new thing. But he is a poor contributor to the stored materials of science.
It is of other stuff that true science is made. And if even years of nominal intercourse and spatial juxtaposition sometimes leave human beings, as regards their inner selves, in the position of strangers still, what shall be said of the attempt to discern the psychic life of animals? Will the touch of curiosity which prompts us to watch the proceedings of the strange creatures,—will a course of experimentation on their behaviour under artificial conditions,—justify us in drawing liberal conclusions as to why they so behaved, [pg xci] and what they thought and felt about it? It is necessary in the first place to know what to observe, and how, and above all what for. But that presumed, we must further live with the animals not only as their masters and their examiners, but as their friends and fellow-creatures; we must be able—and so lightly that no effort is discernable—to lay aside the burden and garb of civilisation; we must possess that stamp of sympathy and similarity which invites confidence, and breaks down the reserve which our poor relations, whether human or others, offer to the first approaches of a strange superior. It is probable that in that case we should have less occasion to wonder at their oddities or to admire their sagacity. But a higher and more philosophical wonder might, as in other cases when we get inside the heart of our subject, take the place of the cheap and childish love of marvels, or of the vulgar straining after comic traits.
Of all this mass of materials the psychologist proper can directly make only a sparing use. Even as illustrations, his data must not be presented too often in all their crude and undigested individuality, or he runs the risk of leaving one-sided impressions. Every single instance, individualised and historical,—unless it be exhibited by that true art of genius which we cannot expect in the average psychologist—narrows, even though it be but slightly, the complete and all-sided truth. Anecdotes are good, and to the wise they convey a world of meaning, but to lesser minds they sometimes suggest anything but the points they should accentuate. Without the detail of individual realistic study there is no psychology worth the name. History, story, we must have: but at the same time, with the philosopher, we must say, I don't give much weight to stories. And this is what will always—except in rare instances where [pg xcii] something like genius is conjoined with it—make esoteric science hard and unpopular. It dare not—if it is true to its idea—rest on any amount of mere instances, as isolated, unreduced facts. Yet it can only have real power so far as it concentrates into itself the life-blood of many instances, and indeed extracts the pith and unity of all instances.
Nor, on the other hand, can it turn itself too directly and intently towards practical applications. All this theory of mental progress from the animate soul to the fullness of religion and science deals solely with the universal process of education: “the education of humanity” we may call it: the way in which mind is made true and real46. It is therefore a question of intricacy and of time how to carry over this general theory into the arena of education as artificially directed and planned. To try to do so at a single step would be to repeat the mistake of Plato, if Plato may be taken to suppose (which seems incredible) that a theoretical study of the dialectics of truth and goodness would enable his rulers, without the training of special experience, to undertake the supreme tasks of legislation or administration. All politics, like all education, rests on these principles of the means and conditions of mental growth: but the schooling of concrete life, though it may not develop the faculty of formulating general laws, will often train better for the management of the relative than a mere logical Scholastic in first or absolute principles.
In conclusion, there are one or two points which seem of cardinal importance for the progress of psychology. (1) Its difference from the physical sciences has to be set out: in other words, the peculiarity of psychical fact. It will not do merely to say that experience marks [pg xciii] out these boundaries with sufficient clearness. On the contrary, the terms consciousness, feeling, mind, &c., are evidently to many psychologists mere names. In particular, the habits of physical research when introduced into mental study lead to a good deal of what can only be called mythology. (2) There should be a clearer recognition of the problem of the relations of mental unity to mental elements. But to get that, a more thorough logical and metaphysical preparation is needed than is usually supposed necessary. The doctrine of identity and necessity, of universal and individual, has to be faced, however tedious. (3) The distinction between first-grade and second-grade elements and factors in the mental life has to be realised. The mere idea as presentative or immediate has to be kept clear of the more logico-reflective, or normative ideas, which belong to judgment and reasoning. And the number of these grades in mental development seems endless. (4) But, also, a separation is required—were it but temporary—between what may be called principles, and what is detail. At present, in psychology, “principles” is a word almost without meaning. A complete all-explaining system is of course impossible at present and may always be so. Yet if an effort of thought could be concentrated on cardinal issues, and less padding of conventional and traditional detail were foisted in, much might thereby be done to make detailed research fruitful. (5) And finally, perhaps, if psychology be a philosophical study, some hint as to its purpose and problem would be desirable. If it is only an abstract branch of science, of course, no such hint is in place.
