Rene Descartes' Meditations on First Philosophy In Focus contains the excellent and popular Elizabeth S. Haldane and G.R.T. Ross translation of Rene Descartes' Meditations on First Philosophy. It also contains a portion of the Replies to Objections II, in which Descartes discusses how the method employed in the Meditations, which he calls ``analysis,'' differs from the method of ``synthesis'' employed by the geometer. In his introduction, Stanley Tweyman provides a fresh and detailed discussion of the relationship between Descartes' Rules for the Direction of the Mind and the method of ``analysis,'' and their applications to the Meditations. The six critical papers drawn together in this book present a broad and exegetical commentary on the Meditations and give an indication of the diversity of scholarly opinion which exists on the topic of method in Descartes' philosophy. An extensive bibliography is also included.
