Abstract

This article pursues two objectives through a close reading of Newton’s 1713 General Scholium. First, it examines his relationship to the canonical mechanical philosophy, including his response to criticism of his own theory that that canonical philosophy’s requirements motivated. Second, it presents an interpretation of Newton’s own mechanical philosophy, glimpsed in draft material for the General Scholium: he takes the natural world to be a machine operating by causal principles that arise only within systems and that require mathematical methods because they fundamentally involve interdependent and thus co-varying quantities. Newton’s realism about impressed forces links the two objectives examined.
