“Common sense is not so common.”

“Let us read, and let us dance; these two amusements will never do any harm to the world.”

“Every man is guilty of all the good he did not do.”

“Doubt is not a pleasant condition, but certainty is absurd.”

“The more I read, the more I acquire, the more certain I am that I know nothing.”

“It is difficult to free fools from the chains they revere.”

“Think for yourselves and let others enjoy the privilege to do so too.”
