Do not indoctrinate your children. Teach them how to think for themselves, how to evaluate evidence, and how to disagree with you.

But what, after all, is faith? It is a state of mind that leads people to believe something - it doesn't matter what - in the total absence of supporting evidence. If there were good supporting evidence then faith would be superfluous, for the evidence would compel us to believe it anyway. It is this that makes the often-parroted claim that 'evolution itself is a matter of faith' so silly. People believe in evolution not because they arbitrarily want to believe it but because of overwhelming, publicly available evidence.

Nature is not cruel, only pitilessly indifferent. This is one of the hardest lessons for humans to learn. We cannot admit that things might be neither good nor evil, neither cruel nor kind, but simply callous-indifferent to all suffering, lacking all purpose.

If you look up at the Milky Way through the eyes of Carl Sagan, you get a feeling in your chest of something greater than yourself. And it is. But it's not supernatural.

Isaac Asimov's remark about the infantilism of pseudoscience is just as applicable to religion: 'Inspect every piece of pseudoscience and you will find a security blanket, a thumb to suck, a skirt to hold.' It is astonishing, moreover, how many people are unable to understand that 'X is comforting' does not imply 'X is true'.

Religion is the root of quite a lot of evil.

Religion and science have nothing to do with each other, they're about different things, science is about the way the world works and religion is about [...] miracles. [...] And in any case, if you ask most ordinary people in church or in a mosque why they believe, it's almost certainly got something to do with the belief that God does wonderful things, that God intervenes, that God heals the sick, that God answers prayers, God forgives sins.
