The overall goal of the intelligent design movement is to overthrow materialism and atheism. Its proponents believe that society has suffered "devastating" cultural consequences from adopting materialism and that science is the cause of the decay into materialism because it seeks only natural explanations, and is therefore atheistic. They believe that the scientific theory of evolution implies that humans have no spiritual nature, no moral purpose, and no intrinsic meaning. They seek to "reverse the stifling dominance of the materialist worldview", represented by the theory of evolution, in favor of "a science consonant with Christian and theistic convictions."
