Many a doctrine is like a window pane. We see truth through it but it divides us from truth.

The teacher who is indeed wise does not bid you to enter the house of his wisdom but rather leads you to the threshold of your mind.

A little knowledge that acts is worth infinitely more than much knowledge that is idle.

Wisdom stands at the turn in the road and calls upon us publicly, but we consider it false and despise its adherents.

Wisdom ceases to be wisdom when it becomes too proud to weep, too grave to laugh, and too selfish to seek other than itself.
