The Art of Controversy (or The Art of Being Right), is an acidulous and sarcastic treatise written by the German philosopher Arthur Schopenhauer in sardonic deadpan. In it, Schopenhauer examines a total of thirty-eight methods of showing up one's opponent in a debate. He introduces his essay with the idea that philosophers have concentrated in ample measure on the rules of logic, but have not (especially since the time of Immanuel Kant) engaged with the darker art of the dialectic, of controversy.
