Deism

Deism is the belief that reason and observation of the natural world are sufficient to determine the existence of a creator, accompanied with the rejection of revelation and authority as a source of religious knowledge. Deism became more prominent in the 17th and 18th centuries during the Age of Enlightenment—especially in Britain, France, Germany and America—among intellectuals raised as Christians who believed in one god, but found fault with organized religion and could not believe in supernatural events such as miracles, the inerrancy of scriptures, or the Trinity.

Deism is derived from deus, the Latin word for god. The earliest known usage in print of the English term deist is 1621, and deism is first found in a 1675 dictionary. Deistic ideas influenced several leaders of the American and French Revolutions. Two main forms of deism currently exist: classical deism and modern deism.
