When I meet people who say - which they do all of the time - 'I must just tell you, my great aunt had cancer of the elbow and the doctors gave her 10 seconds to live, but last I heard she was climbing Mount Everest,' and so forth, I switch off quite early.

Religion has run out of justifications. Thanks to the telescope and the microscope, it no longer offers an explanation of anything important. Where once it used to able, by its total command of a worldview, to prevent the emergence of rivals, it can now only impede and retard-or try to turn back-the measureable advances that we have made.

The moment of near despair is quite often the moment that precedes courage.

I have no time to waste on this planet being told what to do by those who think that God has given them instructions.

Religion is not the belief there is a god. Religion is the belief god tells you what to do.

If you want to stay in for the long haul, and lead a life that is free from illusions either propagated by you or embraced by you, then I suggest you learn to recognize and avoid the symptoms of the zealot and the person who knows he is right. For the dissenter, the skeptical mentality is at least as important as any armor of principle.
