Finally, atheists claim that faith is the height of delusion, and yet everybody, including atheists, have faith in something. G.K. Chesterton is reported to have said, “If man doesn’t believe in God, he will believe in anything.” Once atheists leave traditional faiths, they gravitate to new, secular alternatives, such as Marxism, political progressivism, humanism, postmodernism, or scientism—every one of which is based on assumptions that require remarkable leaps of faith to accept.
