The Enlightenment Thought, born in the Eighteenth Century, shows a characteristic that places the reason at center. It can be said that the Enlightenment was symbolically a period beginning with the English Revolution of 1688 and reaching the peak by the French Revolution of 1789. In earlier periods, though a “new” politics and society emerged, the thinkers did not take a complete stance against to the “old” one. However, in the process that started with the Enlightenment, almost everything about the old one became clearer. In this respect, the Enlightenment has risen over an anti-tradition.
