Intelligent design
Empirical science uses the scientific method to create "a posteriori" knowledge based on observation and repeated testing of hypotheses and theories. Intelligent design proponents seek to change this fundamental basis of science by eliminating "methodological naturalism" from science and replacing it with what the leader of the intelligent design movement, Phillip E. Johnson, calls "theistic realism". Some have called this approach "methodological supernaturalism", which means belief in a transcendent, nonnatural dimension of reality inhabited by a transcendent, nonnatural deity. Intelligent design proponents argue that naturalistic explanations fail to explain certain phenomena and that supernatural explanations provide a very simple and intuitive explanation for the origins of life and the universe. Proponents say evidence exists in the forms of irreducible complexity and specified complexity that cannot be explained by natural processes. They also hold that religious neutrality requires the teaching of both evolution and intelligent design in schools, saying that teaching only evolution unfairly discriminates against those holding creationist beliefs. Teaching both, they argue, allows for the possibility of religious belief, without causing the state to actually promote such beliefs. Many intelligent design followers believe that "Scientism" is itself a religion that promotes secularism and materialism in an attempt to erase theism from public life, and they view their work in the promotion of intelligent design as a way to return religion to a central role in education and other public spheres. Some allege that this larger debate is often the subtext for arguments made over intelligent design, though others note that intelligent design serves as an effective proxy for the religious beliefs of prominent intelligent design proponents in their efforts to advance their religious point of view within society.
