Let us suppose, then, that one who himself justly estimates the imagination is anxious to develop its operation in his child. No doubt the best beginning, especially if the child be young, is an acquaintance with nature, in which let him be encouraged to observe vital phenomena, to put things together, to speculate from what he sees to what he does not see. But let earnest care be taken that upon no matter shall he go on talking foolishly. Let him be as fanciful as he may, but let him not, even in his fancy, sin against fancy’s sense; for fancy has its laws as certainly as the most ordinary business of life. When he is silly, let him know it and be ashamed. But where this association with nature is but occasionally possible, recourse must be had to literature. In books, we not only have store of all results of the imagination, but in them, as in her workshop, we may behold her embodying before our very eyes, in music of speech, in wonder of words, till her work, like a golden dish set with shining jewels, and adorned by the hands of the cunning workmen, stands finished before us. In this kind, then, the best must be set before the learner, that he may eat and not be satisfied; for the finest products of the imagination are of the best nourishment for the beginnings of that imagination. And the mind of the teacher must mediate between the work of art and the mind of the pupil, bringing them together in the vital contact of intelligence; directing the observation to the lines of expression, the points of force; and helping the mind to repose upon the whole, so that no separable beauties shall lead to a neglect of the scope--that is the shape or form complete. And ever he must seek to _show_ excellence rather than talk about it, giving the thing itself, that it may grow into the mind, and not a eulogy of his own upon the thing; isolating the point worthy of remark rather than making many remarks upon the point. Especially must he endeavour to show the spiritual scaffolding or skeleton of any work of art; those main ideas upon which the shape is constructed, and around which the rest group as ministering dependencies. But he will not, therefore, pass over that intellectual structure without which the other could not be manifested. He will not forget the builder while he admires the architect. While he dwells with delight on the relation of the peculiar arch to the meaning of the whole cathedral, he will not think it needless to explain the principles on which it is constructed, or even how those principles are carried out in actual process. Neither yet will the tracery of its windows, the foliage of its crockets, or the fretting of its mouldings be forgotten. Every beauty will have its word, only all beauties will be subordinated to the final beauty--that is, the unity of the whole.
