Aristotle’s Dialectical Consideration of the Infinite

Abstract Aristotle’s exploration of the infinite in his Physics III employs a dialectical method to clarify its nature within natural reality. By engaging with his predecessors’ positions, Aristotle delineates three meanings of ‘infinite’, focusing on a traversable, termless principle. His dialectic reveals that the infinite lacks simultaneous actual existence, existing instead in potency, but with a successive actuality in time and motion. This nuanced account resolves apparent contradictions by positing the infinite as homonymous, applying analogously to time, motion, number, and magnitude divisibility. Aristotle’s ‘infinite in potency’ accommodates diverse interpretations – capacity for divisibility and process for time – unifying them through matter as their foundation. This approach untangles dialectical impasses, aligns with observed properties, and explains Aristotle’s predecessors’ varied positions. Recognizing the infinite’s analogous nature resolves scholarly disputes, while affirming its grounding in a material as subject to continuous quantity.
