But kindness, never. Our ancestors didn't use the word, and they did not greatly value the quality — except perhaps insofar as they valued compassion.

“At the rate of progress since 1800, every American who lived into the year 2000 would know how to control unlimited power. He would think in complexities unimaginable to an earlier mind. He would deal with problems altogether beyond the range of earlier society. To him the nineteenth century would stand on the same plane with the fourth — equally childlike — and he would only wonder how both of them, knowing so little, and so weak in force, should have done so much.”
The Education of Henry Adams (1907)
Context: For this new creation, born since 1900, a historian asked no longer to be teacher or even friend; he asked only to be a pupil, and promised to be docile, for once, even though trodden under foot; for he could see that the new American — the child of incalculable coal-power, chemical power, electric power, and radiating energy, as well as of new forces yet undetermined — must be a sort of God compared with any former creation of nature. At the rate of progress since 1800, every American who lived into the year 2000 would know how to control unlimited power. He would think in complexities unimaginable to an earlier mind.

Context: People sometimes say: "we are in a society that is all rotten, all dishonest." That is not true. There are still so many good people, so many honest people. Rather, what can be done to improve society? I would say: let each of us try to be good and to infect others with a goodness imbued with the meekness and love taught by Christ. Christ's golden rule was: "do not do to others what you do not want done to yourself. Do to others what you want done to yourself." 'And he always gave. Put on the cross, not only did he forgive those who crucified him, but he excused them. He said: "Father, forgive them for they know not what they do." This is Christianity, these are sentiments which, if put into practice would help society so much.
