 In the older literature, it was assumed that determinism is the working hypothesis of science, and that to reject determinism is to be against science. This no longer seems plausible. Some people think that quantum physics has shown determinism to be false. This remains controversial (Albert 1992; Loewer 1996b; P. Lewis 2016), but it is now generally agreed that we can reject determinism without accepting the view that the behavior of human beings falls outside the scope of natural laws. If naturalism is the thesis that human behavior can be explained in the same kind of way—in terms of events, natural processes, and laws of nature—as everything else in the universe, then we can reject determinism without rejecting naturalism.
