It is plain, for one thing, that under the new state of things specialism, in the future, must more and more abound. But specialism means subdivision of labor; and with subdivision labor ought to be more completely, more exactly, performed. Let us bow our heads to the inevitable; the day of encyclopaedic learning has gone by. It may perhaps be said that that sun set with Leibnitz. But as little learning is only dangerous when it forgets that it is little, so specialism is only dangerous when it forgets that it is special. When it encroaches on its betters, when it claims exceptional certainty or honor, it is impertinent, and should be rebuked; but it has its own honor in its own province, and is, in any case, to be preferred to pretentious and flaunting sciolism. A vast, even a bewildering prospect is before us, for evil or for good; but for good, unless it be our own fault, far more than for evil. Books require no eulogy from me; none could be permitted me, when they already draw their testimonials from Cicero[4] and Macaulay.[5] But books are the voices of the dead. They are a main instrument of communion with the vast human procession of the other world. They are the allies of the thought of man. They are in a certain sense at enmity with the world. Their work is, at least, in the two higher compartments of our threefold life. In a room well filled with them, no one has felt or can feel solitary. Second to none, as friends to the individual, they are first and foremost among the compages, the bonds and rivets of the race, onward from that time when they were first written on the tablets of Babylonia and Assyria, the rocks of Asia minor, and the monuments of Egypt, down to the diamond editions of Mr. Pickering and Mr. Frowde.[6] It is in truth difficult to assign dimensions for the libraries of the future. And it is also a little touching to look back upon those of the past. As the history of bodies cannot, in the long run, be separated from the history of souls, I make no apology for saying a few words on the libraries which once were, but which have passed away.
