An atheist believes that a hospital should be built instead of a church. An atheist believes that deed must be done instead of prayer said.An atheist strives for involvement in life and not escape into death. He wants disease conquered, poverty vanished, war eliminated.

Atheism may be defined as the mental attitude which unreservedly accepts the supremacy of reason and aims at establishing a lifestyle and ethical outlook verifiable by experience and the scientific method, independent of all arbitrary assumptions of authority and creeds.

I told my kids I just want three words on my tombstone, if I have one. I'll probably be cremated. One is woman. I'm very comfortable in that role. I've loved being a woman, I've loved being a mother, I've loved being a grandmother. I want three words: Woman, Atheist, Anarchist. That's me.

An Atheist is a person who questions every kind of authority, and this is the thing that is important. Because if we can, without blinking an eye, question the ultimate authority, god - who must be obeyed, then we can question the authority of the state, we can question the authority of a university structure, we can question the authority of our employer, we can question anything. So I think the primary thing that an Atheist is, is a person who looks at an authoritarian idea, or an authority structure, and says to that authority structure: from whence do you derive your authority and why should I be obedient to you? It appears to me that if I have human intelligence that this is enough for me to try to challenge whatever you're doing.
