What's Wrong with Religion? Why Be So Hostile?

Core idea

Colleagues who share Dawkins's atheism still ask why he is so hostile — isn't religion harmless? This, the book's most polemical topic, is his answer: religion is not harmless, and even moderate faith makes the world safer for fundamentalism.

Dawkins's argument: Fundamentalist religion actively debauches the scientific enterprise. It teaches people not to change their minds and not to want to know things that are there to be known.

Why it matters

The question "why be hostile?" is the hinge of the whole book. If religion were merely private and harmless, polemic would be misplaced. Dawkins's reply is that faith's effects — on science education, on law, on tolerance — are public and real.

Practical application

Telling confidence from fundamentalism

Dawkins offers a test: ask what evidence would change a person's mind. A scientist can name it; a fundamentalist, by his account, cannot. The willingness to be wrong is the dividing line.

Reading the absolutism debate

On contested issues — abortion, euthanasia — Dawkins frames the divide as absolutist ("is it human?") versus consequentialist ("can it suffer?"). Recognising which question is being asked clarifies many otherwise deadlocked arguments.

Example

Dawkins recounts the geologist Kurt Wise, Harvard-trained, who took scissors to his Bible and cut out every verse incompatible with science — and found so little left that he chose to discard science instead, abandoning his career. Dawkins treats this as the topic's clearest illustration: a self-inflicted wound, easily avoidable, that he attributes to the "mental torture" of literalist faith. Whatever one makes of the verdict, the case shows what is at stake in the topic's argument.
