“When a nation forgets her skill in war, when her religion becomes a mockery, when the whole nation becomes a nation of money-grabbers, then the wild tribes, the barbarians drive in… Who will our invaders be? From whence will they come?”

Context: He remembered his wife's even goodness during thirty years. Not anything in detail — not courtship or early raptures —but just the unvarying virtue, that seemed to him a woman's noblest quality. So many women are capricious, breaking into odd flaws of passion or frivolity. Not so his wife. Year after year, summer and winter, as bride and mother, she had been the same, he had always trusted her. Her tenderness! Her innocence! The wonderful innocence that was hers by the gift of God. Ruth knew no more of worldly wickedness and wisdom than did the flowers in her garden, or the grass in her field. Her idea of business — "Henry, why do people who have enough money try to get more money?" Her idea of politics — "I am sure that if the mothers of various nations could meet, there would be no more wars," Her idea of religion — ah, this had been a cloud, but a cloud that passed. She came of Quaker stock, and he and his family, formerly Dissenters, were now members of the Church of England. The rector's sermons had at first repelled her, and she had expressed a desire for "a more inward light," adding, "not so much for myself as for baby" (Charles). Inward light must have been granted, for he heard no complaints in later years. They brought up their three children without dispute. They had never disputed.
She lay under the earth now. She had gone, and as if to make her going the more bitter, had gone with a touch of mystery that was all unlike her.

The History of Freedom in Christianity (1877)
Context: John Knox thought that every Catholic in Scotland ought to be put to death; and no man ever had disciples of a sterner or more relentless temper. But his counsel was not followed.
All through the religious conflict, policy kept the upper hand. When the last of the Reformers died, religion, instead of emancipating the nations, had become an excuse for the criminal art of despots. Calvin preached, and Bellarmine lectured; but Machiavelli reigned.

Context: The choice is with us still, but the civilization now in jeopardy is all humanity. As the ancient myth makers knew, we are children equally of the earth and the sky. In our tenure on this planet we've accumulated dangerous evolutionary baggage — propensities for aggression and ritual, submission to leaders, hostility to outsiders — all of which puts our survival in some doubt. But we've also acquired compassion for others, love for our children and desire to learn from history and experience, and a great soaring passionate intelligence — the clear tools for our continued survival and prosperity. Which aspects of our nature will prevail is uncertain, particularly when our visions and prospects are bound to one small part of the small planet Earth. But up there in the immensity of the Cosmos, an inescapable perspective awaits us. There are not yet any obvious signs of extraterrestrial intelligence and this makes us wonder whether civilizations like ours always rush implacably, headlong, toward self-destruction. National boundaries are not evident when we view the Earth from space. Fanatical ethnic or religious or national chauvinisms are a little difficult to maintain when we see our planet as a fragile blue crescent fading to become an inconspicuous point of light against the bastion and citadel of the stars. Travel is broadening.
