You are now about to enter on a Profession which has the means of doing much good to society, and scarcely any temptation to do harm. You may encourage Genius, you may chastise superficial Arrogance, expose Falsehood, correct Error, and guide the Taste and Opinions of the Age in no small degree by the books you praise and recommend. And this too may be done without running the risk of making any enemies; or subjecting yourself to be called to account for your criticism, however severe. While your name is unknown, your person is invulnerable: at the same time your aim is sure, for you may take it at your leisure; and your blows fall heavier than those of any Writer whose name is given, or who is simply anonymous. There is a mysterious authority in the plural, _We_, which no single name, whatever may be its reputation, can acquire; and, under the sanction of this imposing style, your strictures, your praises, and your dogmas, will command universal attention; and be received as the fruit of united talents, acting on one common principle--as the judgments of a tribunal who decide only on mature deliberation, and who protect the interests of Literature with unceasing vigilance. Such being the high importance of that Office, and such its opportunities; I cannot bestow a few hours of leisure better than in furnishing you with some hints for the more easy and effectual discharge of it: hints which are, I confess, loosely thrown together; but which are the result of long experience, and of frequent reflection and comparison. And if anything should strike you, at first sight, as rather equivocal in point of morality, or deficient in liberality and feeling; I beg you will suppress all such scruples, and consider them as the offspring of a contracted education and narrow way of thinking, which a little intercourse with the World and sober reasoning will speedily overcome. Now as in the conduct of life nothing is more to be desired than some Governing Principle of action, to which all other principles and motives must be made subservient; so in the Art of Reviewing I would lay down as a fundamental position, which you must never lose sight of, and which must be the mainspring of all your criticisms--_Write what will sell!_ To this Golden Rule every minor canon must be subordinate; and must be either immediately deducible from it, or at least be made consistent with it. Be not staggered at the sound of a precept which, upon examination, will be found as honest and virtuous as it is discreet. I have already sketched out the great services which it is in your power to render mankind; but all your efforts will be unavailing if men did not read what you write. Your utility therefore, it is plain, depends upon your popularity; and popularity cannot be attained without humouring the taste and inclinations of men.
