paying under the terms of the original agreement (having not yet won a lawsuit), and if he won there would still be no penalty, since he would be awarded the money at issue. At this point, the judge throws both of them out of court, remarking "κακοῦ κόρακος κακὸν ᾠόν" ("a bad egg from a bad crow"). Logic Corax is probably best known for developing the "reverse-probability argument", also known as the Art of Corax. If a person is accused of a crime which he is not likely to have committed (for example, a small man physically attacking a large man, against whom he is almost certainly doomed to fail), his defense will be that it is unlikely that the crime occurred. His argument draws on the lack of means of the accused. However, if a person is accused of a crime which he is likely to have committed (in the case of a larger man attacking a smaller man), he can also use the defense that it is unlikely that he did it, for the very reason that it appears too probable. This man draws on the lack of prospect of getting away unsuspected. It works by anticipating the audience's expectations, and then combatting that expectation with a countermove. This pattern of anticipating and then contradicting an audience's expectation has continued to be a typical move in reverse probability arguments to this day. Of course, another countermove of this same type can also be employed (it could be argued that the large man could have committed the crime precisely because he thought he would be too obvious a suspect), and then another, and then another. For this reason, the Art of Corax has been labeled a "logical paradox". This method of argumentation has also been called quasi-logical: "it maintains that self-referential logic that is typical of the human mind even if it is circular."
