A healthy mode of reading would follow the lines of a sound education. And the first canon of a sound education is to make it the instrument to perfect the whole nature and character. Its aims are comprehensive, not special; they regard life as a whole, not mental curiosity; they have to give us, not so much materials, as capacities. So that, however moderate and limited the opportunity for education, in its way it should be always more or less symmetrical and balanced, appealing equally in turn to the three grand intellectual elements--imagination, memory, reflection: and so having something to give us in poetry, in history, in science, and in philosophy. And thus our reading will be sadly one-sided, however voluminous it be, if it entirely close to us any of the great types and ideals which the creative instinct of man has produced, if it shut out from us either the ancient world, or other European poetry, as important almost as our own. When our reading, however deep, runs wholly into "pockets," and exhausts itself in the literature of one age, one country, one type, then we may be sure that it is tending to narrow or deform our minds. And the more it leads us into curious byways and nurtures us into indifference for the beaten highways of the world, the sooner we shall end, if we be not specialists and students by profession, in ceasing to treat our books as the companions and solace of our lifetime, and in using them as the instruments of a refined sort of self-indulgence. A wise education, and so judicious reading, should leave no great type of thought, no dominant phase of human nature, wholly a blank. Whether our reading be great or small, so far as it goes, it should be general. If our lives admit of but a short space for reading, all the more reason that, so far as may be, it should remind us of the vast expanse of human thought, and the wonderful variety of human nature. To read, and yet so to read that we see nothing but a corner of literature, the loose fringe, or flats and wastes of letters, and by reading only deepen our natural belief that this island is the hub of the universe, and the nineteenth century the only age worth notice, all this is really to call in the aid of books to thicken and harden our untaught prejudices. Be it imagination, memory, or reflection that we address--that is, in poetry, history, science, or philosophy, our first duty is to aim at knowing something at least of the best, at getting some definite idea of the mighty realm whose outer rim we are permitted to approach.
