Abstract
Humanists expound the virtues of science and reason. Emphasis is placed on formulating theories and predictions with clarity and precision, focusing wherever possible on phenomena that are mathematically quantifiable and can be objectively and precisely measured. Science and reason offer us truth‐sensitive ways of arriving at beliefs. As a result of scientific investigation, many religious claims, or claims endorsed by religion, have been shown to be false, or at least rather less well founded than previously thought. So science has threatened and indeed established beyond reasonable doubt the falsity of some religious beliefs. Science and reason are able to threaten, and indeed demolish, many religious beliefs. When religious and other woo‐claims are challenged by science and reason, various strategies may be employed in their defence. Some of the strategies are selective scepticism, re‐interpretation and accusation of scientism.
