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.
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.
What I'm asking you to entertain is that there is nothing we need to believe on insufficient evidence in order to have deeply ethical and spiritual lives.
The core of science is not a mathematical modeling--it is intellectual honesty. It is a willingness to have our certainties about the world constrained by good evidence and good argument.
It is time that we admitted that faith is nothing more than the license religious people give one another to keep believing when reasons fail.
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.
It is time that scientists and other public intellectuals observed that the contest between faith and reason is zero-sum.
