Seven common logical fallacies

The famous French philosopher Descartes once said, "I think, therefore I am".

The great soul shines with the light of thought. Before we think correctly, we must learn to recognize the fallacies in ordinary logic.

The first hasty premise

A hasty premise means that the discussion is caused by inappropriate induction. For example, traveling is a good thing, so everyone should travel.

"Traveling is a good thing" is a wrong generalization. For example, if you have high blood pressure and coronary heart disease, it is not a good thing to travel in the mountains. Your induction must be correct. You can say that traveling is good for most people, otherwise you will make the fallacy of hasty premise.

Article 2 Overgeneralization

For example, Xiaoming, a student in your class, doesn't want to learn English, Xiaohong doesn't want to learn Chinese, and Xiaoli doesn't want to learn math. Just say that the students in your class don't like studying.

Is this conclusion too fast? Because the proven examples are not enough to support your conclusion.

Article 3 Abuse of Causality

For example, we should not go out with a car washer, because every time we drive, the car will break down.

What does the car break down have to do with the car washer?

Article 4 Contradictory premise

There is a famous example of contradictory premise-if God is omnipotent, can he create a stone that he can't move?

If you can create such a thing, then he can't move it, but is it inconsistent to say that God is omnipotent? And vice versa!

Article 5 Infiltrate sympathy

For example, a boy confessed to his beloved girl. He said, "honey, my whole world is dark without you." I can't eat and sleep at night without you. My world really can't live without you, dear, marry me! "

This is a typical sympathy infiltration. He didn't propose, but talked about some tragic situations to win the other party's pity and win his request.

Article 6 Hypothesis contrary to the facts

The frequently used sentence pattern: "If I could, I would" doesn't actually exist. In this case, we must be wary of taking assumptions as true things.

The seventh well was poisoned.

Two people are arguing. The first man stood up and said,' This man is a complete liar. We can't believe what he said. And at the moment his opponent didn't speak. This phenomenon is called well poisoning.

In other words, no one can poison the water before drinking it, and you can't break your opponent's hamstring before he opens his mouth.
