Thought once awakened does not again slumber.

We are no more responsible for the evil thoughts that pass through our minds than a scarecrow for the birds which fly over the seedplot he has to guard. The sole responsibility in each case is to prevent them from settling.

The quality of our lives is closely related to the quality of our thinking.

I think, therefore I am.

Nurture your mind with great thoughts; to believe in the heroic makes heroes.

Beware when the great God lets loose a thinker on this planet.

Look sharply after your thoughts. They come unlooked for, like a new bird seen on your trees, and, if you turn to your usual task, disappear; and you shall never find that perception again; never, I say-but perhaps years, ages, and I know not what events and worlds may lie between you and its return.

Our best thoughts come from others.

So far as a man thinks, he is free.

The soul of God is poured into the world through the thoughts of men.
