I have sworn upon the altar of God, eternal hostility against every form of tyranny over the mind of man.
You will never do anything in this world without courage. It is the greatest quality of the mind next to honor.
Beauty is no quality in things themselves: it exists merely in the mind which contemplates them.
Happiness doesn’t depend on any external conditions, it is governed by our mental attitude.
My religion consists of a humble admiration of the illimitable superior spirit who reveals himself in the slight details we are able to perceive with our frail and feeble mind.
When you hear a man say, “I hate”, adding the name of some race, nation, religion, or social class, you are dealing with a belated mind. That man may dress like a modern, ride in an automobile, listen over the radio, but his mind is properly dated about 1000 B.C.
The whole art of teaching is only the art of awakening the natural curiosity of young minds for the purpose of satisfying it afterwards.
The improvement of the mind improves the heart and corrects the understanding.
The man who never in his mind and thoughts travel’d to heaven is no artist.
There is as much greatness of mind in acknowledging a good turn as in doing it.
