Did You Know?

Belief in God based on reason rather than revelation or the teaching of any specific religion is known as deism. The word originated in England in the early 17th century as a rejection of orthodox Christianity. Deists asserted that reason could find evidence of God in nature and that God had created the world and then left it to operate under the natural laws devised by God. By the late 18th century, deism was the dominant religious attitude among Europe’s educated classes; it was accepted by many upper-class Americans of the same era, including the first three US presidents.
