From the very outset of his literary and intellectual career Rousseau saw himself as an uncompromising critic of contemporary society. As he has vividly related in his personal writings, the famous moment of ‘illumination’ when he was on the way to visit his friend Diderot imprisoned in the Chateau de Vincennes not only gave him a vision of ‘another universe’ but transformed him into ‘another man’. An overwhelming ‘enthusiasm for truth, freedom and virtue’ made him henceforth reject the corrupt values of the society he saw around him; ‘to be free and virtuous and above fortune and opinion’ seemed a greater and nobler attitude than servile acquiescence in the ‘maxims of his age’.
