The doer alone learneth.

Deeds uninformed by educated thought can take false directions. When we go into action and confront our adversaries, we must be as armed with knowledge as they.

It is not when truth is dirty, but when it is shallow, that the lover of knowledge is reluctant to step into its waters.

The man of knowledge must be able not only to love his enemies but also to hate his friends.

It is not enough to prove something, one also has to seduce or elevate people to it. That is why the man of knowledge should learn how to speak his wisdom: and often in such a way that it sounds like folly!

Close beside my knowledge lies my black ignorance.
