Reveal the logical contradiction of the other party's point of view

Reasoning according to the other party's logic, reveals the logical contradiction of the other party's point of view, and makes it self negate.

Aristotle, an ancient Greek scholar, believed that the falling speed of an object is directly proportional to its weight. Galileo used this method in refuting this conclusion. Galileo said: "according to Aristotle, if a 100 pound ball and a 1 pound ball fall from the same height at the same time, the 100 pound ball should land before the 1 pound ball. If you tie a 100 pound ball and a 1 pound ball together and let it fall from a high place, according to Aristotle's logic, it can draw two different conclusions: one is that if the two balls are connected together, their weight is 1 pound heavier than a 100 pound ball, so they should land first; the other is that a 1 pound ball is connected with a 100 pound ball, because the 1 pound ball is heavier than a 100 pound ball If a 100 pound ball falls slowly, the falling speed of a one pound ball will certainly slow down the falling speed of a 100 pound ball. In this way, two balls tied together should land behind a 100 pound ball. " Galileo drew two contradictory conclusions from Aristotle's judgment by using the method of logical reasoning, which made Aristotle's judgment theoretically self defeating.
