Einstein, too, was unable to make a clean break with time. "To those of us who believe in physics," he wrote to the widow of a friend who had recently died, "this separation between past, present, and future is only an illusion, if a stubborn one." When his own turn came, a couple of weeks later, he said, "It is time to go."
Mathematical beauty, like the beauty of, say, a late Beethoven quartet, arises from a combination of strangeness and inevitability.
Higher mathematics was invented by the Pythagoreans, a cult whose tenets included the transmigration of souls and the sinfulness of eating beans.

Truth is what your contemporaries let you get away with.
"[Richard Rorty] also liked to cite Nietzsche’s observation that truth is a surrogate for God.

This kind of steadfast unfaith completely overthrew the more typical religious faith I had had up to that point, kind of like Zeus overthrowing Cronus.
Ya'know... WWI ended in 1918, and WWII started in 1939. That's not a ton of time after "the war to end all wars", like when I think about how long life has felt since Y2K.
