Be an atheist if you want, but do not believe in anything unquestioningly.

Do not go through life like leaf blown from here to there believing whatever you are told.

When you propose ridiculous things to believe, too many men will choose to believe nothing at all.

The uninitiated are those who believe in nothing except what they can grasp in their hands, and who deny the existence of all that is invisible.

If you want to be a good saddler, saddle the worst horse; for if you can tame one, you can tame all.

I know you won't believe me, but the highest form of Human Excellence is to question oneself and others.
