Life is a Mystery, not a problem waiting to be solved.

Earnestly I must exert myself in order to return as much as I have received.

The world we have created is a product of our thinking.

For an idea that does not first seem insane, there is no hope.

If you want your children to be intelligent, read them fairy tales. If you want them to be more intelligent, read them more fairy tales.

For the moral attitudes of a people that is supported by religion need always aim at preserving and promoting the sanity and vitality of the community and its individuals, since otherwise this community is bound to perish. A people that were to honour falsehood, defamation, fraud, and murder would be unable, indeed, to subsist for very long.

The most important decision we make is whether we believe we live in a friendly or hostile universe.
