Thomas Aquinas states parenthetically, as something entirely obvious, that men are more rational than women. For my part, I see no evidence of this.

It has been said that man is a rational animal. All my life I have been searching for evidence which could support this.

What science cannot discover, mankind cannot know.

A habit of basing convictions upon evidence, and of giving to them only that degree or certainty which the evidence warrants, would, if it became general, cure most of the ills from which the world suffers.

That Plato's Republic should have been admired, on its political side, by decent people, is perhaps the most astonishing example of literary snobbery in all history.

Televison allows thousands of people to laugh at the same joke and still remain alone.

Although this may seem a paradox, all exact science is based on the idea of approximation. If a man tells you he knows a thing exactly, then you can be safe in inferring that you are speaking to an inexact man.
