Modern men of letters may be divided into three classes; the mere scholar or _book-worm_, all whose knowledge is taken from books, and who may be passed by as an obsolete character, little inquired after—the literary _hack_ or coffee-house politician, who gets his information mostly from hearsay, and who makes some noise indeed, but the echo of it does not reach beyond his own club or circle—and the man of real or of pretended genius, who aims to draw upon his own resources of thought or feeling, and to throw a new light upon nature and books. This last personage (if he acts up to his supposed character) has too much to do to lend himself to a variety of pursuits, or to lay himself out to please in all companies. He has a task in hand, a vow to perform; and he cannot be diverted from it by incidental or collateral objects. All the time that he does not devote to this paramount duty, he should have to himself, to repose, to lie fallow, to gather strength and recruit himself. A boxer is led into the lists that he may not waste a particle of vigour needlessly; and a leader in Parliament, on the day that he is expected to get up a grand attack or defence, is not to be pestered with the ordinary news of the day. So an author (who is, or would be thought original) has no time for _spare_ accomplishments or ornamental studies. All that he intermeddles with must be marshalled to bear upon his purpose. He must be acquainted with books and the thoughts of others, but only so far as to assist him on his way, and ‘to take progression from them.’ He starts from the point where _they_ left off. All that does not aid him in his new career goes for nothing, is thrown out of the account; or is a useless and splendid incumbrance. Most of his time he passes in brooding over some wayward hint or suggestion of a thought, nor is he bound to give any explanation of what he does with the rest. He tries to melt down truth into essences—to express some fine train of feeling, to solve some difficult problem, to start what is new, or to perfect what is old; in a word, not to do what others can do (which in the division of mental labour he holds to be unnecessary), but to do what they all with their joint efforts cannot do. For this he is in no hurry, and must have the disposal of his leisure and the choice of his subject. The public can wait. He deems with a living poet, who is an example of his own doctrine— ——‘That there are powers Which of themselves our minds impress; That we can feed this mind of ours In a wise passiveness.’ Or I have sometimes thought that the dalliance of the mind with Fancy or with Truth might be described almost in the words of Andrew Marvell’s address ‘To his Coy Mistress:‘—
