The dramatist sets in operation a chain of circumstances in which his characters are unconsciously brought to book by their own past. The method of the naturalistic novelist is quite different; absolved of the necessity of a demonstration, he tends to be less and less concerned with incident and to become preoccupied with the effect of experience on character; the drama is purely internal and is revealed by minute and acute psychological analysis. When this method is applied to dramatic material the very absence of the terms in the demonstration essential to the dramatist produces the effect of irony. Consider, for example, Richard Cory:

[. . . ]

Here we have a man's life-story distilled into sixteen lines. A dramatist would have been under the necessity of justifying the suicide by some train of events in which Richard Cory's character would have inevitably betrayed him. A novelist would have dissected the psychological effects of these events upon Richard Cory. The poet, with a more profound grasp of life than either, shows us only what life itself would show us; we know Richard Cory only through the effect of his personality upon those who were familiar with him, and we take both the character and the motive for granted as equally inevitable. Therein lies the ironic touch, which is intensified by the simplicity of the poetic form in which this tragedy is given expression.
