What are the two major enlightenment ideas that voltaire is remembered for championing

In Europe, thinkers and writers believed that they were "enlightened" — meaning that they had more reason than the common person. The word reason meant a lot during this time. People believed that reason could be used to build a better world. Leaders of the Enlightenment opposed much of religion because of its demands for political obedience and truth based on religious belief rather than on evidence and proof. They also opposed the idea of inherited monarchy because it had no basis in reason and led to abuse of power. American leaders like Jefferson, Franklin and Adams were greatly influenced by many of these philosophers. These new views helped them to show others that the American Revolution wasn't just a rebellion. It was a new design for how to organize a society that was based upon reason and fairness.

No one knows sorry. : )
