 Kant’s philosophy of mathematics is of interest to a variety of scholars for multiple reasons. First, his thoughts on mathematics are a crucial and central component of his critical philosophical system, and so they are illuminating to the historian of philosophy working on any aspect of Kant’s corpus. Additionally, issues of contemporary interest and relevance arise from Kant’s reflections on the most fundamental and elementary mathematical disciplines, issues that continue to inform important questions in the metaphysics and epistemology of mathematics. Finally, disagreements about how to interpret Kant’s philosophy of mathematics have generated a fertile area of current research and debate.
