When did Einstein become the successor to Franklin, Twain, and Will Rogers as the pithy American backwoods purveyor of folk wisdom that we can attribute any nonsense to? Despite the fact that he was theoretical physicist and most of thoughts he asserted would bend our minds just to conceive, he became a social activist in his later years and deigned to speak in language the layperson could understand, but he was no fool and he said no such thing. It's a cute thing for a tee shirt or a bumper sticker, but it has nothing to do with him, and I'd add is a highly debatable point in itself. You may be unhappy only because you didn't think of it first. Tee shirt sales and all, ya know..
