Key points

  • Critically examines Sutherland's argument that Kant considered mathematics a science of magnitudes.
  • Investigates the claim that the world of experience is also a world of magnitudes for Kant.
  • Analyzes the essential role of intuition in representing magnitudes within Kant's philosophy.
  • Reconstructs an eight-step "Master Argument" connecting magnitude and mathematics.
  • Identifies unclarity in Sutherland's argument concerning syntheticity and intuition in proof.

Abstract

Abstract The main claims of Kant’s Mathematical World are that for Kant mathematics is a science of magnitudes, the world of experience is a world of magnitudes, and there is an essential role for intuition in representing magnitudes. This paper critically examines the argument for these main claims. It articulates an eight-step “Master Argument” that connects magnitude to mathematics through a series of intermediary concepts. Some of these steps are left unclear in Kant’s Mathematical World , and I argue that the book’s silence on syntheticity and the role of intuition in proof is a partial cause for this unclarity.
