in 1946 by the French philosopher Jean-Paul Sartre in describing the tactics of anti-Semites: They know that their remarks are frivolous, open to challenge. But they are amusing themselves, for it is their adversary who is obliged to use words responsibly, since he believes in words . . . They delight in acting in bad faith, since they seek not to persuade by sound argument but to intimidate and disconcert.
