Rameau's nephew / d'alembert's dream (Penguin Books)

One of the key figures of the French Enlightenment, Denis Diderot was a passionate critic of conventional morality, society and religion. Among his greatest and most well-known works, these two dialogues are dazzling examples of his radical scientific and philosophical beliefs. In Rameau's Nephew, the eccentric and foolish nephew of the great composer Jean-Philippe Rameau meets Diderot by chance, and the two embark on a hilarious consideration of society, music, literature, politics, morality and philosophy. Its companion-piece, D'Alembert's Dream, outlines a material, atheistic view of the universe, expressed through the fevered dreams of Diderot's friend D'Alembert. Unpublished during his lifetime, both of these powerfully controversial works show Diderot to be one of the most advanced thinkers of his age, and serve as fascinating testament to the philosopher's wayward genius.
