Answer:
Atheism
Explanation:
The Enlightenment, also known as the century of lights and illustration, was an intellectual and philosophical movement that dominated the world of ideas in Europe during the eighteenth century, "The Century of Philosophy."
Many people think that the thinkers of this movement were atheists, but this was rarely the case. Generally, Enlightenment had, within its thinkers, a mix of Christianity and Scientific rationalism in such a way that we have some specific movements with that sort of thinking, such as the Deist movement of the 18th century.
