In 2020 a piece of text attributed to Einstein was distributed - in language that a 1920s German Jew would never have used in any language, but it starts out with the quote, below. Dan MacKay wrote to Vance about it

Einstein wrote (telegraphed, actually) “I believe in Spinoza’s God, who reveals Himself in the lawful harmony of the world, not in a God Who concerns Himself with the fate and the doings of mankind.”

Vance wrote this in reply.
