Towards the end of his life, Descartes published the first four parts of a projected six-part work, The Principles of Philosophy. This was intended to be the definitive statement of his complete system of philosophy. Gaukroger examines the whole system, and reconstructs the last two parts from Descartes' other writings.

This book describes how natural philosophy and exact mathematical sciences joined together to make the Scientific Revolution possible.

Appearing here in English for the first time, this is F. W. J. Schelling's vital document of the attempts of German Idealism and Romanticism to recover a deeper relationship between humanity and nature and to overcome the separation between mind and matter induced by the modern reductivist program. Written in 1799 and building upon his earlier work, First Outline of a System of the Philosophy of Nature provides the most inclusive exposition of Schelling's philosophy of the natural world. He presents a startlingly contemporary model of an expanding and contracting universe; a unified theory of electricity, gravity magnetism, and chemical forces; and, perhaps most importantly, a conception of nature as a living and organic whole.
