The origin of reduction to absurdity
"A Mr. Feng Shui from the south went to the north to see Feng Shui, which coincided with heavy snow. It's a crooked poem: "It doesn't rain when it snows, but it turns into rain when it hits the ground;" "If I knew that snow would turn into rain, why didn't it rain at first?" His crooked poem was just heard by a shepherd boy, and he also made a jingle to satirize Mr. Feng Shui: "Mr. Feng Shui doesn't eat shit when he eats, but it becomes shit when he eats;" If I had known that rice was going to turn into shit, why didn't I eat shit? "
In fact, the little shepherd boy skillfully used the reduction to absurdity to refute Mr. Feng Shui's metaphysical wrong view that he denies the general law of motion of things and only emphasizes the result but not the process of change: assuming that Mr. Feng Shui is telling the truth and only emphasizes the final result of change without changing the process, then, according to his logic, it can be concluded that Mr. Feng Shui should eat shit from the beginning. Of course, Mr. Feng Shui will not admit this fact. Well, obviously, what he said is a fallacy. "
