Jean Jacques Rousseau
He came from a poor, unhappy swiss family. In Paris he always felt out of place in amongst the very sophisticated intellectual people who would gather there. He would complain and critic others constantly. Rousseau would quarrel with the other Philosophes, though his ideas of politics and socials played an important part in the Enlightenment thought. He believed that human nature was generally good and in his opinion it was society that corrupted people. He would argue that all people were equal and that rank and nobility should be abolished, 'Man is born free, and everywhere is in chains'. Revolutionaries in many countries would later adopt his ideas.
