The Foundling, pp. 25–27
The Foundling and Other Tales of Prydain (1973)
Context: ... the book told him of other ways of the world; of cruelty, suffering, and death. He read of greed, hatred, and war; of men striving against one another with fire and sword; of the blossoming earth trampled underfoot, of harvests lost and lives cut short...
But now his heart lifted. These pages told not only of death, but of birth as well; how the earth turns in its own time and in its own way gives back what is given to it; how things lost may be found again; and how one day ends for another to begin. He learned that the lives of men are short and filled with pain, yet each one a priceless treasure, whether it be that of a prince or a pig-keeper. And, at the last, the book taught him that while nothing was certain, all was possible.

Variant: I like pigs. Dogs look up to us. Cats look down on us. Pigs treat us as equals.
Context: [Christopher Soames, Churchill's future son-in-law, remembered] Churchill showing him around Chartwell Farm [around 1946]. When they came to the piggery Churchill scratched one of the pigs and said: I am fond of pigs. Dogs look up to us. Cats look down on us. Pigs treat us as equals.

The Issue (1908)
Context: Now my friends, I am opposed to the system of society in which we live today, not because I lack the natural equipment to do for myself, but because I am not satisfied to make myself comfortable knowing that there are thousands of my fellow men who suffer for the barest necessities of life. We were taught under the old ethic that man's business on this earth was to look out for himself. That was the ethic of the jungle; the ethic of the wild beast. Take care of yourself, no matter what may become of your fellow man. Thousands of years ago the question was asked: "Am I my brother's keeper?" That question has never yet been answered in a way that is satisfactory to civilized society.
Yes, I am my brother's keeper. I am under a moral obligation to him that is inspired, not by any maudlin sentimentality, but by the higher duty I owe to myself. What would you think of me if I were capable of seating myself at a table and gorging myself with food and saw about me the children of my fellow beings starving to death?
