“Predicting the future is a hopeless, thankless task, with ridicule to begin with and, all too often, scorn to end with.”

Context: The future is too interesting and dangerous to be entrusted to any predictable, reliable agency. We need all the fallibility we can get. Most of all, we need to preserve the absolute unpredictability and total improbability of our connected minds. That way we can keep open all the options, as we have in the past.

Context: “Dyrnwyn is yours,” Gwydion said, “as it was meant to be.”
“Yet Arawn is slain,” Taran replied. “Evil is conquered and the blade’s work done.”
“Evil conquered?” said Gwydion. “You have learned much, but learn this last and hardest of lessons. You have conquered only the enchantments of evil. That was the easiest of your tasks, only a beginning, not an ending. Do you believe evil itself so quickly overcome? Not so long as men still hate and slay each other, when greed and anger goad them. Against these even a flaming sword cannot prevail, but only that portion of good in all men’s hearts whose flame can never be quenched.

The History of Freedom in Christianity (1877)
Context: I have reached the end of my time, and have hardly come to the beginning of my task. In the ages of which I have spoken, the history of freedom was the history of the thing that was not. But since the Declaration of Independence, or, to speak more justly, since the Spaniards, deprived of their king, made a new government for themselves, the only known forms of Liberty, Republics and Constitutional Monarchy, have made their way over the world.
