The Unscrupulous Man (Ancient Greek and Modern Greek Αναισχυντια, "Anaischuntia") is one of Theophrastus's Characters[1]. The first description of a psychopath, he was a glib, pathological liar with no remorse or guilt for his actions.
"The Unscrupulous Man will go and borrow more money from a creditor he has never paid ... When marketing he reminds the butcher of some service he has rendered him and, standing near the scales, throws in some meat, if he can, and a soup-bone. If he succeeds, so much the better; if not, he will snatch a piece of tripe and go off laughing."
