How many times can a man go down and still be alive?

I have four daughters and eight grandchildren. My soul lives on in them. That's immortality. That's the only immortality I care about.

From the outer edge of his life, looking back, there was only one remorse, and that was only that he wished to go on living.

Time was a film run backward. Suns fled and ten million moons fled after them.

I would not see our candle blown out in the wind. It is a small thing, this dear gift of life handed us mysteriously out of immensity. I would not have that gift expire... If I seem to be beating a dead horse again and again, I must protest: No! I am beating, again and again, living man to keep him awake and move his limbs and jump his mind... What's the use of looking at Mars through a telescope, sitting on panels, writing books, if it isn't to guarantee, not just the survival of mankind, but mankind surviving forever!

Man has always been half-monster, half-dreamer.

Work. Don't Think. Relax.
