CHAPTER VIII.
CLASSIFICATION.
“Dans l’ordre historique, la philosophie transcendante a devancé la philosophie élémentaire. Il ne faut point s’en étonner; les grands problèmes de la métaphysique et de la morale se présentent à l’homme, dans l’enfance même de son intelligence, avec une grandeur et une obscurité qui le séduisent et qui l’attirent. L’homme, qui se sent fait pour connoître, court d’abord à la vérité avec plus d’ardeur que de sagesse; il cherche à deviner ce qu’il ne peut comprendre, et se perd dans des conjectures absurdes ou téméraires. Les théogonies et les cosmogonies sont antérieures à la saine physique, et l’esprit humain a passé à travers toutes les agitations et les délires de la métaphysique transcendante avant d’arriver à la psychologie.”—Cousin, Frag. Philos. p. 75.
THE process by which we connect what we call the objects of our senses, and also our ideas, into certain aggregates called classes, is of too much importance not to have attracted the attention of those who have engaged in the study of mind. Yet it is doubtful, whether metaphysicians have regarded CLASSIFICATION as an original power of the mind, or have allowed that what is included under that name might be resolved into simpler elements. The term Abstraction, I think, they have generally taken as the name of a distinct, and original, power, not susceptible of further analysis. But, in doing so, it seems (for the language of writers 248 is too loose on this subject, to allow us the use of more affirmative terms), they have restricted the name to the power of forming such ideas as are represented by the terms, hardness, softness, length, breadth, space, and so on. And this operation they rather consider as subservient to classification, than as that operation itself. The process, however, of grouping individuals into classes, has been regarded as sufficiently mysterious. The nature of it has been the object of deep curiosity; and the erroneous opinions which were entertained of it bewildered, for many ages, the most eminent philosophers; and enfeebled the human mind.
What (it was inquired) is that which is really done by the mind, when it forms individuals into classes; separates such and such things from others, and regards them, under a certain idea of unity, as some thing by themselves? Why is the segregation thought of? And for what end is it made? These questions all received answers; but it was many ages before they received an answer approaching the truth; and it is only necessary to read with care the writings of Plato and of Aristotle, and of all philosophers, with very few exceptions, from theirs to the present time, to see, that a misunderstanding of the nature of General Terms is that which chiefly perplexed them in their inquiries, and involved them in a confusion, which was inextricable, so long as those terms were unexplained.
The process in forming those classes was said to be this. The Mind leaves out of its view this, and that, and the other thing, in which individuals differ from one another; and retaining only those in which they all agree, it forms them into a class. But what is 249 this forming of a class? What does it mean? When I form a material aggregate; when I collect a library; when I build a house; when I even raise a heap of stones; I move the things, whatever they may be, and place them, either regularly or irregularly, in a mass together. But when I form a class, I perform no operation of this sort. I touch not, nor do I in any way whatsoever act upon the individuals which I class. The proceeding is all mental. Forming a class of individuals, is a mode of regarding them. But what is meant by a mode of regarding things? This is mysterious; and is as mysteriously explained, when it is said to be the taking into view the particulars in which individuals agree. For what is there, which it is possible for the mind to take into view, in that in which individuals agree? Every colour is an individual colour, every size is an individual size, every shape is an individual shape. But things have no individual colour in common, no individual shape in common, no individual size in common; that is to say, they have neither shape, colour, nor size in common. What, then, is it which they have in common, which the mind can take into view? Those who affirmed that it was something, could by no means tell. They substituted words for things; using vague and mystical phrases, which, when examined, meant nothing. Plato called it ἰδέα, Aristotle, εἶδος, both, words taken from the verb to see; intimating, something as it were seen, or viewed, as we call it. At bottom, Aristotle’s εἶδος, is the same with Plato’s ἰδέα, though Aristotle makes a great affair of some very trifling differences, which he creates and sets up between them. The Latins, translated both ἰδέα, and 250 εἶδος, by the same words, and were very much at a loss for one to answer the purpose; they used species, derived in like manner from a verb to see, but which, having other meanings, was ill adapted for a scientific word; they brought, therefore, another word in aid, forma, the same with ὅραμα, derived equally from a verb signifying to see, which suited the purpose just as imperfectly as species; and as writers used both terms, according as the one or the other appeared best to correspond with their meaning, they thickened by this means the confusion.
After a time, unfortunately a long time, it began to be perceived, that what was thus represented as the object of the mind in the formation of classes, was chimerical and absurd; when a set of inquirers appeared, who denied the existence of all such objects, affirmed that ideas were all individual, and that nothing was general but names. The question rose to the dignity of a controversy; and to the hateful violence of a religious controversy. They who affirmed the existence of general ideas were called Realists, they who denied their existence Nominalists. There can be no doubt, that of the two the Nominalists approached, by far, the nearest to the truth; and their speculations tended strongly to remove from mental science the confusion in which the total misapprehension of abstract terms had involved it. But the clergy brought religion into the quarrel, and as usual on the wrong side. Realism was preached as the doctrine which alone was consistent with orthodoxy; the Nominalists were hunted down; and persecution, well knowing her object, clung to the books as well as the men; so that the books of the Nominalists, 251 though the art of printing tended strongly to preserve them, were suppressed and destroyed, to such a degree, that it is now exceedingly difficult to collect them; and not easy to obtain copies even of the most remarkable.
The opinion, that the particulars in which the individuals of a class agree were distinct Objects of the Mind, soon made them distinct EXISTENCES; they were the Essence of things; the Eternal Exemplars, according to which individual things were made; they were called UNIVERSALS, and regarded as alone the Objects of the Intellect. They were invariable, always the same; individuals, not the objects of intellect but only the low objects of sense, were in perpetual flux, and never, for any considerable period, the same. Universals alone have Unity; they alone were the subject of science; Individuals were innumerable, every one different from another; and cognoscible only by the lower, the sensitive part of our nature.
Endless were the subtleties into which ingenious men were misled, in the contemplation of those Fictions; and wonderful were the attributes which they bestowed upon them. “It is, then, on these permanent Phantasms,” says Mr. Harris, copying the ancient Philosophers, “that the human mind first works, and by an energy as spontaneous and familiar to its nature, as the seeing of colour is familiar to the eye, it discerns at once what in MANY is ONE; what in things DISSIMILAR and DIFFERENT is SIMILAR and the SAME. By this it comes to behold a kind of superior Objects; a new Race of Perceptions, more comprehensive than those of sense; a Race of Perceptions, each one of which, may be found entire and whole in the separate 252 individuals of an infinite and fleeting multitude, without departing from the unity and permanence of its own nature.”[8*] Here we have something sufficiently mystical; a thing which is, at once, ONE, and MANY; which is ONE, it seems, by its very nature, and yet may exist, entire and whole, in the separate individuals of an infinite MULTITUDE. This is a specimen of their Doctrine; a specimen of what they call THE SUBLIME in Intellection.
