Henri Bergson opens his inquiry by asserting that the comic exists only within the pale of the human and requires a momentary anesthesia of the heart to produce its effect. Laughter, in his view, is essentially a social corrective that penalizes rigidity, absentmindedness, and automatic behavior, demanding instead the constant tension and elasticity necessary for social adaptation. Bergson proceeds to analyze the comic element in forms, movements, and situations, demonstrating how a living body or mind becomes laughable when it reminds us of a mere machine. He examines the mechanics of comedy through various recurring structures, including repetition, inversion, and the reciprocal interference of independent series of events.
Moving from physical gestures to the subtleties of language and wit, the author illustrates how rigid phrases, literal interpretations of metaphors, and transposition into different keys generate comic results. Finally, Bergson turns to character, arguing that comic traits are those unsociable or mechanical flaws that run counter to the flexibility required by community life. Vanity and professional solemnity are scrutinized as primary sources of the laughable, functioning like dreams in their inversion of common sense. Through these detailed analyses, Bergson constructs a comprehensive theory that positions laughter midway between art and life, serving as an instinctive weapon against human automatism.
