"There can't be a practical reason for believing what isn't true. At least I rule it out as impossible. I either think it is true or it isn't; If it is true you should believe it. If it isn't, you shouldn't. If you cant find out whether it's true or it isn't, you should suspend judgment. It seems to me a fundamental dishonesty, a fundamental treachery to hold a belief because you think its useful and not because you think it's true." -Bertrand Russell, 1959
