The American Enlightenment applied scientific reasoning to politics, science, and religion. It promoted religious tolerance and restored literature, arts, and music as important disciplines worthy of study in colleges. A non-denominational moral philosophy replaced theology in many college curricula. Some colleges reformed their curricula to include natural philosophy (science), modern astronomy, and mathematics, and "new-model" American style colleges were founded. Politically, the age is distinguished by an emphasis upon economic liberty, republicanism and religious tolerance, as clearly expressed in the United States Declaration of Independence. Attempts to reconcile science and religion resulted in a rejection of prophecy, miracle, and revealed religion, resulting in an inclination toward deism among some major political leaders of the age.
