The summer night is like a perfection of thought.
Sorrow was like the wind. It came in gusts.
The real problem is not whether machines think but whether men do.
I must create a system, or be enslaved by another man's.
The freethinking of one age is the common sense of the next.
Every moment of one's existence one is growing into more or retreating into less.
Happiness lies in the joy of achievement and the thrill of creative effort.
