There was a man who insisted everything was false. Whenever someone would try and tell him something, "Not true!" he would respond. Why, he was asked, did he refute everything? "Because this way noone deceives me."
But perhaps it was he himself, who it would have to be admitted was also a someone, who was deceiving himself, and even most abominably. Or if not quite he or just he doing the deceiving, someone or something more subtle again, a someone or something with whom he was unconsciously in collusion- for however you look at it he wasn't an entirely passive agent in the process, if process it was.
