 That reorganization dominates Kuhn’s conception of revolutions is apparent throughout his work. As a young scholar he had an epiphany when Aristotle’s seemingly radically false or unintelligible claims suddenly came together for him as a coherent, comprehensive worldview. This experience became Kuhn’s psychological model for revolutionary transformation from one paradigm to its successor and informed his later talk of Gestalt switches. But he also emphasized that revolution involves social reorganization of the field (not merely the cognitive reorganization of an individual), from one form of scientific life to another, incompatible with it. By implication, his structural or formal conception of revolution excluded the alternative idea of revolution as extraordinary bursts in substantive content.
