Philip Windsor (1935-2000) is widely acknowledged to have been among the brightest and most penetrating of thinkers in International Relations. This book brings together some of his most exciting and stimulating essays, covering many of the classic and most enduring issues in International Relations: the causes of wars; intervention and the use of force; the regulation of conflict; human rights and the tensions between order and justice. Windor's philosophical bias, together with his elegant prose and sheer breadth of knowledge, gave an underlying coherence and unity to all his writings. The essays include brilliant essays on East-West relations during the Cold War, arms control, Clausewitz's contribution to strategic thought, Henry Kissinger's scholarly contribution and the place of human rights and cultural dialogue in international politics.
