The Meditations on First Philosophy is one of Descartes's best-known works and one of the most influential philosophical texts ever written.

This treatise offers Descartes' metaphysical views on the relationship between the mind and thought, the nature of reality and how accumulated knowledge and our experiences affect us. First published in 1641, the work consists of six meditations on the following topics: the dubiousness of thoughts and assumptions - as Descartes puts it, 'what can be called into doubt'; the nature of the human mind; the existence of God; truth versus falsehood; the essence of material things and, finally, the difference between mind and body. For anyone interested in the study of philosophy, this is an essential and illuminating read.

This volume also includes the great philosopher's Discourse on the Method, a brilliant discussion of reasoning and experimentation which helped establish the foundations of the scientific process, a selection of enlightening essays from his Principles of Philosophy and a classic introduction by Frank Sewall.
