It is taboo in our society to criticize a persons religious faith... these taboos are offensive, deeply unreasonable, but worse than that, they are getting people killed. This is really my concern. My concern is that our religions, the diversity of our religious doctrines, is going to get us killed. I'm worried that our religious discourse- our religious beliefs are ultimately incompatible with civilization.
If faith is what you have to go on, if faith is the link between your beliefs and the world at large, your beliefs are very likely to be wrong. Beliefs can be right or wrong. If you believe you can fly, that belief is only true if indeed you can fly. Somebody who thinks he can fly, and is wrong about it, will eventually discover there's a problem with his view of the world.
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.
