Laws of nature play a central role in Kant's theoretical philosophy and are crucial to understanding his philosophy of science in particular. In this volume of new essays, the first systematic investigation of its kind, a distinguished team of scholars explores Kant's views on the laws of nature in the physical and life sciences. Their essays focus particularly on the laws of physics and biology, and consider topics including the separation in Kant's treatment of the physical and life sciences, the relation between universal and empirical laws of nature, and the role of reason and the understanding in imposing order and lawful unity upon nature. The volume will be of great interest to advanced students and scholars of Kant's philosophy of science, and to historians and philosophers of science more generally.
