Debate skills of the method of stealing beam and changing column

"Stealing a beam and changing a column" is to replace the old topic with a new one which has direct and inevitable connection with the original topic and is different from the original one, so as to attack from a new angle and try to overcome the enemy. The new proposition should satisfy the following conditions: a (old proposition) must lead to B (new proposition), and B is the result of A. If the premise is proved, the result is tenable; if the result is proved, the existence of the premise is tenable. From this to that, we can prove the old proposition (which is necessarily related to the new one) by proving the conclusion that is beneficial to us. In fact, it is the use of proof to prove the correctness of the result, and the "derived" reason is also correct (the logic may not be correct, but it is often effective in the debate).

Fudan University successfully used this method to defeat the powerful Taiwan University in the 1993 International College debate contest. In the final of the junior college competition, the theme of the debate is the theory of "human nature", which has been debated for thousands of years. As the positive side, Taiwan University thinks "human nature is good", while Fudan University thinks "human nature is evil". We know that if we want to refute the theory of good human nature and establish the theory of evil human nature, we can't avoid answering such a question: since human nature is evil, why are there so many good deeds in society? It's very difficult to answer this question clearly from a positive perspective. In view of this situation, Fudan University does not stick to the established rules and blindly works on the "evil theory of human nature". Instead, it develops a new way and focuses on the perspective of "although human nature is evil, education can be good". It turns the evil of human nature in the original topic into a condition in the new topic. It does not focus on proving it at all, but is based on the "human nature" of education to be good The theory of "to be good" refutes the debate of "human nature is good" in Taiwan University. In fact, it follows such an assumption: if human nature is good, why should it be moralized and good? In this way, the original very difficult problems will be solved, and a new hot potato will be thrown to NTU.
