In the long run, the most influential of all the “Big Three” thinkers of the French Enlightenment was Rousseau. Rousseau stands apart. As a brilliant thinker and writer in his own right, he shocked even the trendy, progressive “salon set” with his radicalism between 1754 and his death in 1778. He further scandalized the elite social set by deliberately affronting the ethical and moral standards of the day. He was an iconoclast par excellence.
