Is life worth living? It all depends on the liver.

There is no more miserable human being than one in whom nothing is habitual but indecision.

Most unhappiness is caused because people listen to themselves... instead of talking to themselves.

In order to disprove the assertion that all crows are black, one white crow is sufficient.

If theological ideas prove to have a value for concrete life, they will be true, for pragmatism, in the sense of being good for so much. How much more they are true, will depend entirely on their relations to the other truths that also have to be acknowledged.

A great idea goes through three stages on its way to acceptance: 1) it is dismissed as nonsense, 2) it is acknowledged as true, but insignificant, 3) finally, it is seen to be important, but not really anything new.

I am no lover of disorder and doubt as such. Rather do I fear to lose truth by this pretension to possess it already wholly.
