There is nothing far-fetched or unreasonable in the idea thus presented to us; and if this be a University, then a University does but contemplate a necessity of our nature, and is but one specimen in a particular medium, out of many which might be adduced in others, of a provision for that necessity. Mutual education, in a large sense of the word, is one of the great and incessant occupations of human society, carried on partly with set purpose, and partly not. One generation forms another; and the existing generation is ever acting and reacting upon itself in the persons of its individual members. Now, in this process, books, I need scarcely say, that is, the _litera scripta_, are one special instrument. It is true; and emphatically so in this age. Considering the prodigious powers of the press, and how they are developed at this time in the never-intermitting issue of periodicals, tracts, pamphlets, works in series, and light literature, we must allow there never was a time which promised fairer for dispensing with every other means of information and instruction. What can we want more, you will say, for the intellectual education of the whole man, and for every man, than so exuberant and diversified and persistent a promulgation of all kinds of knowledge? Why, you will ask, need we go up to knowledge, when knowledge comes down to us? The Sibyl wrote her prophecies upon the leaves of the forest, and wasted them; but here such careless profusion might be prudently indulged, for it can be afforded without loss, in consequence of the almost fabulous fecundity of the instrument which these latter ages have invented. We have sermons in stones, and books in the running brooks; works larger and more comprehensive than those which have gained for ancients an immortality, issue forth every morning, and are projected onwards to the ends of the earth at the rate of hundreds of miles a day. Our seats are strewed, our pavements are powdered, with swarms of little tracts; and the very bricks of our city walls preach wisdom, by informing us by their placards where we can at once cheaply purchase it.
