May the shades of Dr. Johnson, Charles Lamb, Emerson, and all great individualists protect us from bad definitions, and especially from rigid or formal ones! Bad definitions destroy themselves, for if they are thoroughly bad no one believes them, and if they contain those pleasing half truths which a generation loves to suckle upon, why then after their vogue they will wither into nothingness. Such definitions are of the letter, and die by it, but stiff, clumsy definitions kill the spirit. To define a great man by a rigid formula is to sink to the lowest practice of the worst class rooms. To define a tendency so sharply that it cannot flow without breaking the definition, is a lecturer's trick for which audiences should stone him. Solemn generalizations which squat upon a book like an ostrich on a goose egg and hatch out vast moral philosophies are to be dreaded like the devil, as are, equally, the critics with pet theories, who, having defined them, make everything from a squib to an epic fit their definition. Definitions which classify without margins are a special evil: the division into literature and journalism for example, with no allowance for interlocking; or the confident separation of all books into categories of good or bad. Wholesale definitions are also objectionable, where having defined a poem as magazine verse, or a collection of articles as a magazine, or a book as a sex story, or a man as a journalist, or a tendency as erratic or erotic, you think you have said something. May the muse of clear thinking, and the little humorous gods who keep the sense of proportion balancing, protect us from these also. It occurs to me that I have made but a lame attempt to define definition. This, however, is as it should be. For definition, in the sense in which I am using it, like literature, has much of the indefinable. It is a tool merely, or better still, because broader, a device by which the things we enjoy and that profit us may be placed in perspective, ranged, compared, sorted, and distinguished. It is what Arnold meant by seeing steadily and seeing whole. It is the scientist's microscope that defines relationship, and equally the painter's brush that by a touch reveals the hidden shapes of nature and the blend of colors. It is, like these instruments, a _means_ and not an _end._ May pedants, scholiasters, formalists, and dilettantes take to heart this final description of literary definition! Quite unconsciously for the most part, but occasionally with purpose aforethought, the essays in this book have been written as literary definitions. Its unity lies in the attempt, which at least has been sincere, to grasp, turn, study in a serious, humorous, ironical, anything but a flippant mood, the living forms of literature as they have risen into consciousness and challenged definition. THE END.
