_Sir Thomas More_.--If one of the most learned men whom the world has ever seen felt it becoming in him to say this two centuries ago, how infinitely smaller in these days must the share of learning which the most indefatigable student can hope to attain, be in proportion to what he must wish to learn! The sciences are simplified as they are improved; old rubbish and demolished fabrics serve there to make a foundation for new scaffolding, and more enduring superstructures; and every discoverer in physics bequeaths to those who follow him greater advantages than he possessed at the commencement of his labours. The reverse of this is felt in all the higher branches of literature. You have to acquire what the learned of the last age acquired, and in addition to it, what they themselves have added to the stock of learning. Thus the task is greater in every succeeding generation, and in a very few more it must become manifestly impossible. _Montesinos_. Pope Ganganelli is said to have expressed a whimsical opinion that all the books in the world might be reduced to six thousand volumes in folio--by epitomising, expurgating, and destroying whatever the chosen and plenipotential committee of literature should in their wisdom think proper to condemn. It is some consolation to know that no Pope, or Nero, or Bonaparte, however great their power, can ever think such a scheme sufficiently within the bounds of possibility for them to dream of attempting it; otherwise the will would not be wanting. The evil which you anticipate is already perceptible in its effects. Well would it be if men were as moderate in their desire of wealth, as those who enter the ranks of literature, and lay claim to distinction there, are in their desire of knowledge! A slender capital suffices to begin with, upon the strength of which they claim credit, and obtain it as readily as their fellow adventurers in trade. If they succeed in setting up a present reputation, their ambition extends no further. The very vanity which finds its present food produces in them a practical contempt for any fame beyond what they can live to enjoy; and this sense of its insignificance to themselves is what better minds hardly attain, even in their saddest wisdom, till this world darkens upon them, and they feel that they are on the confines of eternity. But every age has had its sciolists, and will continue to have them; and in every age literature has also had, and will continue to have its sincere and devoted followers, few in number, but enough to trim the everlasting lamp. It is when sciolists meddle with State affairs that they become the pests of a nation; and this evil, for the reason which you have assigned, is more likely to increase than to be diminished. In your days all extant history lay within compassable bounds: it is a fearful thing to consider now what length of time would be required to make studious man as
