Denis Diderot was born at Langres in eastern France in 1713. After graduating in Paris in 1732, he was nominally a law student for ten years, but was actually leading a precarious bohemian but studious existence. In the early 1740s he met three contemporaries who were of great significance to him and to the age: a'Alembert, Condillac and Rousseau, who assisted Diderot in the compilation of the Encyclopedie, which he worked on until its completion in 1773. Interested in the mind-body dichotomy, his work was a bold mixture of science and philosophy. He died in 1784.Leonard Tancock was a Fellow of University College, London and translated numerous texts for the Penguin Classics until his death in 1986.
