"Nobody knows, of course, precisely what a Jew is. Not even the Supreme Court of Israel could come up with a satisfactory definition as late as 1962. While Swope was aware that in practice a Jew is anyone anybody else thinks is Jewish, he liked to describe himself, when he gave the problem any thought at all, as occupying a “twilight zone” between Jews and non-Jews. He may have visualized himself as being uniquely equipped to serve as a liaison man between the groups--a double agent, as it were, without squalid overtones of espionage." --p428
