Themes in Kant's Metaphysics and EthicsIntended for those interested in Kant's contribution to philosophy, this volume provides an overview of Kant's arguments concerning central issues in metaphysics and ethics. Arthur Melnick argues that the key to all of Kant's arguments is his constructivist theory of space and time. Melnick shows that Kant's arguments for causation and for substance, as well as Kant's refutation of Cartesian skepticism, are far more cogent than usually thought.
