12. Formal Logic I

It is similar with all fallacies, for example with the so-called crocodile conclusion: An Egyptian woman saw how her child playing by the Nile was seized by a crocodile. At the mother's request, the crocodile promises to return the child if the mother guesses what it will do now. The mother now utters: You will not give me back my child. - The crocodile replies: You may have spoken the truth or a lie, but I do not have to give the child back. Because if your speech is true, you will not get it back according to your own saying. But if it is false, then I do not return it according to our agreement. - The mother: I may have spoken the truth or spoken falsely, but you must give me back my child. Because if my speech is true, then you must give it to me according to our agreement; but if it is false, then the opposite must be true. You will give me back my child. The same applies to the conclusion that affected a teacher and a student. The teacher has taught the pupil the art of jurisprudence. The pupil is to pay the last half of the fee only after he has won his first case. After the teaching is completed, the pupil delays the beginning of the practice of law and therefore also the payment. Finally, the teacher sues him, saying to him: “Foolish youth! In any case, you must now pay. For if I win the lawsuit, you must pay according to the judgment; if you win, you must pay according to the contract, for you have won your first lawsuit. But the student: Wise teacher! Under no circumstances do I have to pay. For if the judges rule in my favor, I have nothing to pay according to the judgment; but if they rule against me, I pay nothing according to our contract.
