“Nobel Prize-winning philosopher/mathematician, Bertrand Russell, explains why he does not believe in God.”
Interviewer: Why are you not a Christian?
Russell: Because I see no evidence whatever for any of the Christian dogmas. I have examined all of the stock arguments in favor of the existence of God and none of them seem to me to be logically valid.
Interviewer: Do you think there is a practical reason for having a religious belief for many people?
Russell: Well there can’t be a practical reason to believing what isn’t true. I rule it out as impossible. Either a thing is true or it isn’t. If it is true you should believe it and if it isn’t you shouldn’t. And if you cannot find out if it is true or isn’t you should suspend judgement. It seems to me a fundamental dishonesty and a fundamental treachery to intellectual integrity to hold a belief because you think it is useful and not because you think it is true.
