Argument is meant to reveal the truth, not to create it.

Everyone has the right to doubt everything as often as he pleases and the duty to do it at least once. No way of looking at things is too sacred to be reconsidered. No way of doing things is beyond improvement.

When the story of these times gets written, we want it to say that we did all we could, and it was more than anyone could have imagined.

What the joke displays is a switch in perception. This is important in changing the way we think.

The simple process of focusing on things that are normally taken for granted is a powerful source of creativity.

We may have a perfectly adequate way of doing something, but that does not mean there cannot be a better way. So we set out to find an alternative way. This is the basis of any improvement that is not fault correction or problem solving.

We need both information and thinking. Information is no substitute for thinking and thinking is no substitute for information.
