Progress is man's ability to complicate simplicity.

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.

Land! An island! We devoured it greedily with our eyes and woke the others, who tumbled out drowsily and stared in all directions as if they thought our bow was about to run on to a beach. Screaming seabirds formed a bridge across the sky in the direction of the distant island, which stood out sharper against the horizon as the red background widened and turned gold with the approach of the sun and the full daylight.

It is also rarer to find happiness in a man surrounded by the miracles of technology than among people living in the desert of the jungle and who by the standards set by our society would be considered destitute and out of touch.

...arranging the journey was so difficult. Getting home again was much easier.

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.

It is progress when weapons are improved to kill more people at a longer range.
