“Why not give up the pain, the injury, the slow and terminal? He worried and fretted how cool his skin had become. He understood how at the end a freezing man felt alive with heat and a drowned man could breathe and a burning man became cold and shivered and then died.”

Book XLII: Ch. 18: A summary of the changes which have occurred around the globe in my lifetime
Mémoires d'outre-tombe (1848 – 1850)
Context: How small man is on this little atom where he dies! But how great his intelligence! He knows when the face of the stars must be masked in darkness, when the comets will return after thousands of years, he who lasts only an instant! A microscopic insect lost in a fold of the heavenly robe, the orbs cannot hide from him a single one of their movements in the depth of space. What destinies will those stars, new to us, light? Is their revelation bound up with some new phase of humanity? You will know, race to be born; I know not, and I am departing.

The Pragmatics of Patriotism (1973)
Context: I said that "Patriotism" is a way of saying "Women and children first." And that no one can force a man to feel this way. Instead he must embrace it freely. I want to tell about one such man. He wore no uniform and no one knows his name, or where he came from; all we know is what he did.
In my home town sixty years ago when I was a child, my mother and father used to take me and my brothers and sisters out to Swope Park on Sunday afternoons. It was a wonderful place for kids, with picnic grounds and lakes and a zoo. But a railroad line cut straight through it.
One Sunday afternoon a young married couple were crossing these tracks. She apparently did not watch her step, for she managed to catch her foot in the frog of a switch to a siding and could not pull it free. Her husband stopped to help her.
But try as they might they could not get her foot loose. While they were working at it, a tramp showed up, walking the ties. He joined the husband in trying to pull the young woman's foot loose. No luck —
Out of sight around the curve a train whistled. Perhaps there would have been time to run and flag it down, perhaps not. In any case both men went right ahead trying to pull her free... and the train hit them.
The wife was killed, the husband was mortally injured and died later, the tramp was killed — and testimony showed that neither man made the slightest effort to save himself.
The husband's behavior was heroic... but what we expect of a husband toward his wife: his right, and his proud privilege, to die for his woman. But what of this nameless stranger? Up to the very last second he could have jumped clear. He did not. He was still trying to save this woman he had never seen before in his life, right up to the very instant the train killed him. And that's all we'll ever know about him.
This is how a man dies.
This is how a man... lives!
