The drama of Corneille deals with what is extraordinary, but in what is extraordinary it seeks for truth. He finds the marvellous in the triumphs of the human will. His great inventive powers were applied to creating situations for the manifestation of heroic energy. History attracted him, because a basis of fact seemed to justify what otherwise could not be accepted as probable. Great personages suited his purpose, because they can deploy their powers on the amplest scale. His characters, men and women, act not through blind, instinctive passion, but with deliberate and intelligent force; they reason, and too often with casuistical subtlety, about their emotions. At length he came to glorify the will apart from its aims and ends, when tending even to crime, or acting, as it were, in the void. He thought much of the principles of his art, and embodied his conclusions in critical dissertations and studies of his own works. He accepted the rule of the unities of place and time (of which at first he was ignorant) as far as his themes permitted, as far as the rules served to concentrate action and secure verisimilitude. His mastery in verse of a masculine eloquence is unsurpassed; his dialogue of rapid statement and swift reply is like a combat with Roman short swords; in memorable single lines he explodes, as it were, a vast charge of latent energy, and effects a clearance for the progress of his action. His faults, like his virtues, are great; and though faults and virtues may be travestied, both are in reality alike inimitable.
