A literary critic, a genuine one, should carry in his brain an arsenal of opposites. He should combine common sense with tact, integrity with indulgence, breadth with keenness, vigor with delicacy, largeness with subtlety, knowledge with geniality, inflexibility with sinuousness, severity with suavity; and, that all these counter qualities be effective, he will need constant culture and vigilance, besides the union of reason with warmth, of enthusiasm with self-control, of wit with philosophy,--but hold: at this rate, in order to fit out the critic, human nature will have to set apart its highest and best. Dr. Johnson declared, the poet ought to know everything and to have seen everything, and the ancients required the like of an orator. Truly, the supreme poet should have manifold gifts, be humanly indued as generously and completely as is the bust of Homer, ideally shaped by the light of the infallible artistic instinct and insight of the Greeks. The poet, it is true, must be born a poet, and the critic is the child of culture. But as the poet, to perfect his birthright, has need of culture, so the man whom culture can shape and sharpen to the good critic, must be born with many gifts, to be susceptible of such shaping. And when we reflect that the task of the critic is to see clearly into the subtlest and deepest mind, to measure its hollows and its elevations, to weigh all its individual and its composite powers, and, that from every one of the throbbing aggregates, whom it is his office to analyze and portray, issue lines that run on all sides into the infinite, we must conclude that he who is to be the accomplished interpreter, the trusted judge, should be able swiftly to follow these lines.
