Descartes' Meditations, one of the most influential works in western philosophy, continues to provoke discussion and debate. This volume of essays by leading established and emerging early modern scholars ranges over all six of the Meditations and explores issues such as scepticism, judgement, causation, the proofs for God's existence, the real distinction argument, the nature of personhood and the essence of the mind. The contributors bring new insights to both central and less-studied topics in the Meditations, and connect the work with the rich historical and intellectual context in which Descartes forged his thought. The resulting volume will appeal to a wide range of scholars of early modern thought.
