Johnson is best known as one of the founders of the intelligent design movement, principal architect of the wedge strategy, author of the Santorum Amendment, and one of the ID movement's most prolific authors. Johnson is co-founder and program advisor of the Discovery Institute's Center for Science and Culture. Johnson has advocated strongly in the public and political spheres for the teaching of intelligent design as preferable to the teaching of evolution, which Johnson characterizes as "atheistic" and "falsified by all of the evidence" and whose "logic is terrible." In portraying the philosophy of science, and by extension its theories such as evolution as atheistic, Johnson argues that a more valid alternative is "theistic realism." Theistic realism asserts that science, by relying upon methodological naturalism, demands an "a priori" adoption of a naturalistic philosophy that wrongly dismisses out of hand any explanation that contains a supernatural cause.
