In a city a man may feel second to none. But alone in the immensity of the universe, among all the creatures that preceded man and built up the human species, even a most fervent atheist will wonder if Darwin found the visible road but not the invisible mechanism.

Circumstances cause us to act the way we do. We should always bear this in mind before judging the actions of others. I realized this from the start during World War II.

Once in a while you find yourself in an odd situation. You get into it by degrees and in the most natural way but, when you are right in the midst of it, you are suddenly astonished and ask yourself how in the world it all came about.

This world has seen a great many civilizations. And many of them have survived for longer periods than ours up to the present. They were all as sure as we are today of having founded the first eternal civilization. We today differ from them in having our western civilization spread to embrace the entire planet, leaving no room on any continent for any other culture to take over if we fail.

Progress is man's ability to complicate simplicity.

I also believe that when one dies, one may wake up to the reality that proves that time does not exist.
