One will rarely err if extreme actions be ascribed to vanity, ordinary actions to habit, and mean actions to fear.

Someone else's action should not determine your response.

Many a one commits a reprehensible action, who is at bottom an honourable man, because man seldom acts upon natural impulse, but from some secret passion of the moment which lies hidden and concealed within the narrowest folds of his heart.

It is a mistake, too, to say that the face is the mirror of the soul. The truth is, men are very hard to know, and yet, not to be deceived, we must judge them by their present actions, but for the present only.

I can calculate the motion of heavenly bodies, but not the madness of people.

If you treat people right they will treat you right - ninety percent of the time.
