The first modern translation of the complete texts of La Mettrie's pioneering L'Homme machine and L'Homme plante, first published in 1747 and 1748, respectively, this volume also includes translations of the advertisement and dedication to L'Homme machine. Justin Leiber's introduction illuminates the radical thinking and advocacy of the passionate La Mettrie and provides cogent analysis of La Mettrie's relationship to such important philosophical figures as Descartes, Malebranche, and Locke, and of his lasting influence on the development of materialism, cognitive studies, linguistics, and other areas of intellectual inquiry.
