Mistakes are, after all, the foundations of truth,...

Knowledge rests not upon truth alone, but upon error also.

Knowing your own darkness is the best method for dealing with the darknesses of other people.

If there is anything that we wish to change in the child, we should first examine it and see whether it is not something that could better be changed in ourselves.

The really frightening thing about middle age is the knowledge that you'll grow out of it.

If repression has indeed been the fundamental link between power, knowledge, and sexuality since the classical age, it stands to reason that we will not be able to free ourselves from it except at a considerable cost.

We are approaching a new age of synthesis. Knowledge cannot be merely a degree or a skill... it demands a broader vision, capabilities in critical thinking and logical deduction without which we cannot have constructive progress.

It is error alone which needs the support of government. Truth can stand by itself.
