This seems relevant.
“It’s a wonder I haven’t abandoned all my ideals, they seem so absurd and impractical. Yet I cling to them because I still believe, in spite of everything, that people are really good at heart.
It’s utterly impossible for me to build my life on a foundation of chaos, suffering and death. I see the world being slowly transformed into a wilderness, I hear the approaching thunder that, one day, will destroy us too, I feel the sufferings of millions. And yet, when I look up at the sky, I somehow feel that everything will change for the better, that this cruelty too will end, and that peace and tranquility will return once more.”

“I speak of peace, therefore, as the necessary, rational end of rational men.”
“What kind of peace do I mean and what kind of a peace do we seek? Not a Pax Americana enforced on the world by American weapons of war. Not the peace of the grave or the security of the slave. I am talking about genuine peace, the kind of peace that makes life on earth worth living, and the kind that enables men and nations to grow, and to hope, and build a better life for their children — not merely peace for Americans but peace for all men and women, not merely peace in our time but peace in all time…I speak of peace, therefore, as the necessary, rational end of rational men. I realize the pursuit of peace is not as dramatic as the pursuit of war, and frequently the words of the pursuers fall on deaf ears. But we have no more urgent task…Our problems are manmade; therefore, they can be solved by man. And man can be as big as he wants. No problem of human destiny is beyond human beings. Man’s reason and spirit have often solved the seemingly unsolvable, and we believe they can do it again…And if we cannot end now our differences, at least we can help make the world safe for diversity. For in the final analysis, our most basic common link is that we all inhabit this small planet. We all breathe the same air. We all cherish our children’s futures. And we are all mortal.”
From Carl Sagan’s “Cosmos” (p. 283):
“We have held the peculiar notion that a person or society that is a little different from us, whoever we are, is somehow strange or bizarre, to be distrusted or loathed. Think of the negative connotations of words like ‘alien’ or ‘outlandish.’ And yet the monuments and cultures of each of our civilizations merely represent different ways of being human. An extraterrestrial visitor, looking at the differences among human beings and their societies, would find those differences trivial compared to the similarities. The Cosmos may be densely populated with intelligent beings. But the Darwinian lesson is clear: There will be no humans elsewhere. Only here. Only on this small planet. We are a rare as well as endangered species. Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another.”
