But there is much more than this. Even to those who resolutely avoid the idleness of reading what is trivial, a difficulty is presented--a difficulty every day increasing by virtue even of our abundance of books. What are the subjects, what are the class of books we are to read, in what order, with what connection, to what ultimate use or object? Even those who are resolved to read the better books are embarrassed by a field of choice practically boundless. The longest life, the greatest industry, joined to the most powerful memory, would not suffice to make us profit from a hundredth part of the world of books before us. If the great Newton said that he seemed to have been all his life gathering a few shells on the shore, whilst a boundless ocean of truth still lay beyond and unknown to him, how much more to each of us must the sea of literature be a pathless immensity beyond our powers of vision or of reach--an immensity in which industry itself is useless without judgment, method, discipline; where it is of infinite importance what we can learn and remember, and of utterly no importance what we may have once looked at or heard of. Alas! the most of our reading leaves as little mark even in our own education as the foam that gathers round the keel of a passing boat! For myself, I am inclined to think the most useful help to reading is to know what we should not read, what we can keep out from that small cleared spot in the overgrown jungle of "information," the corner which we can call our ordered patch of fruit-bearing knowledge. The incessant accumulation of fresh books must hinder any real knowledge of the old; for the multiplicity of volumes becomes a bar upon our use of any. In literature especially does it hold--that we cannot see the wood for the trees. How shall we choose our books? Which are the best, the eternal, indispensable books? To all to whom reading is something more than a refined idleness these questions recur, bringing with them the sense of bewilderment; and a still, small voice within us is for ever crying out for some guide across the Slough of Despond of an illimitable and ever-swelling literature. How many a man stands beside it, as uncertain of his pathway as the Pilgrim, when he who dreamed the immortal dream heard him "break out with a lamentable cry; saying, what shall I do?"
