Abstract
Intelligent design (ID) raises several challenges for the relation between science and religion. One's views on these matters ramify across the other sciences, including physics. Can design, especially supernatural design, play any legitimate role in science? Is the ID question just a matter of evidence? What is the proper role for naturalism in all this? These are important questions in the philosophy of science. Before taking them up, this chapter briefly looks at the core concepts used in ID today. There is a less visible but equally menacing problem for the viability of ID. Methodological naturalism (MN) gets a lot of attention, but there is another methodological shaping principle to be contended with, namely, conservatism. Conservatism is also the reason ID attracts so many theists and few nontheists. If one already believes in an intelligence that can play the role of designer, then ID‐based science is not a radical move.
