THE ACQUISITION OF IDEAS

THE images of our past experiences, of whatever nature they may be, visual or verbal, blurred and dim, vivid and distinct, abstract or concrete, need not be memory images, in the strict sense of the word. That is, they need not rise before the mind in a marginal fringe or context of concomitant circumstances, which mean for us their date. They may be mere conceptions, floating pictures of an object, or of its type or class. In this undated condition, we call them products of 'imagination or conception.' Imagination is the term commonly used where the object represented is thought of as an individual thing. Conception is the term where we think of it as a type or class. For our present purpose the distinction is not important; and I will permit myself to use either the word conception,' or the still vaguer word idea,' to designate the inner objects of contemplation, whether these be individual things, like the sun' or 'Julius Cæsar,' or classes of

things, like animal kingdom,' or, finally, entirely abstract attributes, like 'rationality' or 'rectitude.'

The result of our education is to fill the mind little by little, as experiences accrete, with a stock of such ideas. In the illustration I used at our first meeting, of the child snatching the toy and getting slapped, the vestiges left by the first experience answered to so many ideas which he acquired thereby,― ideas that remained with him associated in a certain order, and from the last one of which the child eventually proceeded to act. The sciences of grammar and of logic are little more than attempts methodically to classify all such acquired ideas and to trace certain laws of relationship among them. The forms of relation between them, becoming themselves in turn noticed by the mind, are treated as conceptions of a higher and more abstract order, as when we speak of a 'syllogistic relation' between propositions, or of four quantities making a 'proportion,' or of the 'inconsistency' of two conceptions, or the implication of one in the other.

So you see that the process of education, taken in a large way, may be described as nothing but the process of acquiring ideas or conceptions,

the best educated mind being the mind which has the largest stock of them, ready to meet the largest possible variety of the emergencies of life. The lack of education means only the failure to have acquired them, and the consequent liability to be floored' and 'rattled' in the vicissitudes

of experience.

In all this process of acquiring conceptions, a certain instinctive order is followed. There is a native tendency to assimilate certain kinds of conception at one age, and other kinds of conception at a later age. During the first seven or eight years of childhood the mind is most interested in the sensible properties of material things. Constructiveness is the instinct most active; and by the incessant hammering and sawing, and dressing and undressing dolls, putting of things together and taking them apart, the child not only trains the muscles to co-ordinate action, but accumulates a store of physical conceptions which are the basis of his knowledge of the material world through life. Object-teaching and manual training wisely extend the sphere of this order of acquisition. Clay, wood, metals, and the various kinds of tools are made to contribute to the store. A youth brought up with a sufficiently

broad basis of this kind is always at home in the world. He stands within the pale. He is acquainted with Nature, and Nature in a certain sense is acquainted with him. Whereas the youth brought up alone at home, with no acquaintance with anything but the printed page, is always afflicted with a certain remoteness from the material facts of life, and a correlative insecurity of consciousness which make of him a kind of alien on the earth in which he ought to feel himself perfectly at home.

I already said something of this in speaking of the constructive impulse, and I must not repeat myself. Moreover, you fully realize, I am sure, how important for life,- for the moral tone of life, quite apart from definite practical pursuits, is this sense of readiness for emergencies which a man gains through early familiarity and acquaintance with the world of material things. To have grown up on a farm, to have haunted a carpenter's and blacksmith's shop, to have handled horses and cows and boats and guns, and to have ideas and abilities connected with such objects are an inestimable part of youthful acquisition. After adolescence it is rare to be able to get into familiar touch with any of these

primitive things. The instinctive propensions have faded, and the habits are hard to acquire.

Accordingly, one of the best fruits of the childstudy' movement has been to reinstate all these activities to their proper place in a sound system of education. Feed the growing human being, feed him with the sort of experience for which from year to year he shows a natural craving, and he will develop in adult life a sounder sort of mental tissue, even though he may seem to be wasting a great deal of his growing time, in the eyes of those for whom the only channels of learning are books and verbally communicated information.

It is not till adolescence is reached that the mind grows able to take in the more abstract aspects of experience, the hidden similarities and distinctions between things, and especially their causal sequences. Rational knowledge of such things as mathematics, mechanics, chemistry, and biology, is now possible; and the acquisition of conceptions of this order form the next phase of education. Later still, not till adolescence is well advanced, does the mind awaken to a systematic interest in abstract human relations- moral relations, properly so called, to sociological ideas

and to metaphysical abstractions.
