We owe to books those general benefits which come from high intellectual action. Thus, I think, we often owe to them the perception of immortality. They impart sympathetic activity to the moral power. Go with mean people, and you think life is mean. Then read Plutarch, and the world is a proud place, peopled with men of positive quality, with heroes and demigods standing around us who will not let us sleep. Then, they address the imagination; only poetry inspires poetry. They become the organic culture of the time. College education is the reading of certain books which the common sense of all scholars agrees will represent the science already accumulated. If you know that,--for instance, in geometry, if you have read Euclid and Laplace,--your opinion has some value; if you do not know these, you are not entitled to give any opinion on the subject. Whenever any skeptic or bigot claims to be heard on the questions of intellect and morals, we ask if he is familiar with the books of Plato, where all his pert objections have once for all been disposed of. If not, he has no right to our time. Let him go and find himself answered there. Meantime, the colleges, whilst they provide us with libraries, furnish no professor of books; and, I think, no chair is so much wanted. In a library we are surrounded by many hundreds of dear friends, but they are imprisoned by an enchanter in these paper and leathern boxes; and though they know us, and have been waiting two, ten, or twenty centuries for us,--some of them,--and are eager to give us a sign, and unbosom themselves, it is the law of their limbo that they must not speak until spoken to; and as the enchanter has dressed them like battalions of infantry in coat and jacket of one cut, by the thousand and ten thousand, your chance of hitting on the right one is to be computed by the arithmetical rule of Permutation and Combination,--not a choice out of three caskets, but out of half a million caskets, all alike. But it happens in our experience, that in this lottery there are at least fifty or a hundred blanks to a prize. It seems, then, as if some charitable soul, after losing a great deal of time among the false books, and alighting upon a few true ones which made him happy and wise, would do a right act in naming those which have been bridges or ships to carry him safely over dark morasses and barren oceans, into the heart of sacred cities, into palaces and temples. This would be best done by those great masters of books who from time to time appear,--the Fabricii, the Seldens, Magliabecchis, Scaligers, Mirandolas, Bayles, Johnsons, whose eyes sweep the whole horizon of learning. But private readers, reading purely for love of the book, would serve us by leaving each the shortest note of what he found.
