Secularism: A belief system, attitude or style of life that denies or ignores the reality of God. Derived from a term that means “worldly,” secularism (and its articulate philosophical expression, secular humanism) focuses on the natural order of things as the only reality. Increasingly, however, secularism can be viewed as an attitude that even affects people who claim to believe in God and the supernatural. Much in modern culture pressures people to live in such a way that God is marginal and insignificant to their daily existence. See also humanism.
