The doorstep to the temple of wisdom is a knowledge of our own ignorance.

The doors of wisdom are never shut.

Those who govern, having much business on their hands, do not generally like to take the trouble of considering and carrying into execution new projects. The best public measures are therefore seldom adopted from previous wisdom, but forced by the occasion.

It is the working man who is the happy man. It is the idle man who is the miserable man.

We are all born ignorant, but one must work hard to remain stupid.
