What we do in every other area of our lives (other than religion), is, rather than respect somebody's beliefs, we evaluate their reasons.

The problem I want to talk to you about tonight is the problem of belief. What does it mean to believe? We use this word all the time, and I think behind it lurk some really extraordinary taboos and confusions. What I want to argue tonight is that how we talk about belief- how we fail to criticize or criticize the beliefs of others, has more importance to us personally, more consequence to us personally and to civilization than perhaps anything else that is in our power to influence.

Words like 'God' and 'Allah' must go the way of 'Apollo' and 'Baal' or they will unmake our world.

The moral truth here is obvious: anyone who feels that the interests of a blastocyst just might supersede the interests of a child with a spinal cord injury has had his moral sense blinded by religious metaphysics.

Rather than bring the full force of our creativity and rationality to bear on the problems of ethics, social cohesion, and even spiritual experience, moderates merely ask that we relax our standard of adherence to ancient superstitions and taboos, while otherwise maintaining a belief system that was passed down to us from men and women whose lives were simply ravaged by their basic ignorance about the world.

Everything we do is for the purpose of altering consciousness. We form friendships so that we can feel certain emotions, like love, and avoid others, like loneliness. We eat specific foods to enjoy their fleeting presence on our tongues. We read for the pleasure of thinking another person's thoughts.

Science does not limit itself merely to what is currently verifiable. But it is interested in questions that are potentially verifiable (or, rather, falsifiable).
