If you press them too closely, they will abruptly fall silent, loftily indicating by some phrase that the time for argument is past. It is not that they are afraid of being convinced. They fear only to appear ridiculous or to prejudice by their embarrassment their hope of winning over some third person to their side.

Two additional sentences at the end of the often posted quote from "Anti-Semite and Jew". Those two sentences were always included in the quote when I first saw it making it's round years ago. Now it takes hunting to find the complete quote. Most sites cut it off after "the time for argument is past". I wonder who would benefit from us forgetting those last two sentences.
