This volume contains a collection of seventeen essays which have been previously published on Kant and an addendum to one of these essays that is here published for the first time. Although these essays cover virtually the full spectrum of the author's work on Kant, ranging from his epistemology, metaphysics, and moral theory to his views on teleology, political philosophy, the philosophy of history, and the philosophy of religion, most of them revolve around three basic themes: the nature of transcendental idealism, freedom of the will, and the purposiveness of nature. The first two of these have been the foci of the author's work on Kant since its inception and the essays dealing with them in this volume are intended as clarifications, elaborations, and further developments of what the author has said on these topics elsewhere. Among their major new elements is the introduction of a significant comparative dimension, which is intended both to place Kant's views in their historical context and to explore their contemporary relevance. To this end, Kant's views are contrasted with those of his major predecessors and immediate successors, as well as present‐day philosophers. The concept of the purposiveness of nature is the major contribution of the third Critique (Critique of the Power of Judgment) to Kant's “critical” philosophy and one the main concerns of the essays dealing with it is to demonstrate its central place in Kant's thought.
