Culture definitions for deism


[ (dee-iz-uhm) ]

The belief that God has created the universe but remains apart from it and permits his creation to administer itself through natural laws. Deism thus rejects the supernatural aspects of religion, such as belief in revelation in the Bible (see also Bible), and stresses the importance of ethical conduct. In the eighteenth century, numerous important thinkers held deist beliefs. (See clockwork universe.)
