Nothing detains the reader's attention more powerfully than deep involutions of distress, or sudden vicissitudes of fortune; and these might be abundantly afforded by memoirs of the sons of literature. They are entangled by contracts which they know not how to fulfill, and obliged to write on subjects which they do not understand. Every publication is a new period of time, from which some increase or declension of fame is to be reckoned. The gradations of a hero's life are from battle to battle, and of an author's from book to book.
