We may agree that education consists in the bringing of the latent possibilities of the individual into action, and one of the most important parts in the process of education is played by memory. The fact that memory places on record our first impression of a thing is the reason why we are able to recognise it on the second occasion: otherwise we should have to make its acquaintance afresh every time. It is memory again which enables us to retain the mental pattern of an action we have once performed, and so to do it the more easily a second time, and on subsequent occasions. Thus we see that everything we express, whether in word, thought, or deed, leaves its mark within us: this impress is, as it were, a brick in our life's edifice, and it has added something to that disposition of mind which constitutes our character. Mental growth is thus profoundly influenced by the things we express, for whatever we express forthwith becomes part of ourselves. Anything, therefore, that teaches us to express the fine, the noble, or the beautiful, leaves the self by the fact of that expression with the impress of that fineness, nobility, or beauty henceforth in the character. We do not mean that by the utterance of a praiseworthy sentiment a man at once grows estimable, but we do mean that the sentiment according to its intrinsic value and worth has become an element in his make-up. We observe every day in the contrary direction that giving vent to continual complaint soon makes a person grow sour-minded: and incidentally it also makes him grow sour-visaged. It is frequently possible to tell a man's philosophy from his countenance. Those whose efforts are devoted to preaching a violent discontent seem to run to type, acquiring a discontented kind of countenance to match their views. Equally so a person whose outlook is more balanced, and whose character is gentler, will gradually inscribe a finer type of characteristic both in mind and body. The case is very much the same with Art. Those to whom Art stands for beauty and love must necessarily be building themselves of their thoughts, and so be tending towards their ideal. Thus so far as music becomes the expression of spirit and love, so far its influence upon the individual is permanent and progressive in these directions.
