Around 1830, Arthur Schopenhauer wrote a short manuscript on the tricks people use to win arguments. It was found among his papers and is known as Die Kunst, Recht zu behalten, The Art of Being Right. The last trick reads: Wenn man merkt, daß der Gegner überlegen ist und man Unrecht behalten wird, so werde man persönlich, beleidigend, grob. When you notice that your opponent is superior and you are going to lose, become personal, insulting and rude. Schopenhauer explains that this means leaving the matter and attacking the person. He calls it an appeal from the powers of the mind to those of the body, or to the animal. His remedy is great composure.
