What are some examples of "logical reasoning" in life?

1. There is such a host who invites two guests, Party A and Party B, to dinner. He and A came to the restaurant and waited for a long time, but B hasn't come yet. The host said to himself, "Hey, it hasn't arrived yet." A listened and thought, "shouldn't I be here?" Then I'm leaving. "The master didn't realize that his words would lead to a conclusion contrary to his wishes, so he was angry with A..

Here, A's idea (that is, the thinking process) is like this:

What should come has not come yet;

I haven't arrived yet;

-

So, I shouldn't have come.

This is an outspoken syllogism.

2. In the initial stage of criminal investigation, many people or things are often included in the scope of investigation, so it is often necessary to deny some of the objects or plots in order to narrow the scope of investigation and determine the criminals. At this time, the negative formula of hypothetical reasoning will be used. For example, among the suspects in a theft case, reconnaissance can infer: "If A is the perpetrator, then he has the time to commit the crime; After investigation, A has no time to commit crimes; Therefore, A is not an actor. "

This is a negative aftereffect of sufficient conditional hypothesis reasoning.

3. China ancient joke collection "Yabantle" records that there is a personal mother who believes in Buddhism and reads "There is no Amitabha in the South" all day long. So one day, the man got up early in the morning and shouted, "Mom!" " Mother promised him. After a while, he shouted, "Mom!" Mother promised him again. But this man kept shouting. Mother finally shouted tired and said angrily, "No! Not here! Are you bored? " The man smiled and said, "I only called you a few times, and you were unhappy." I don't know how many times you call Amitabha every day, and I don't know how he should lose his temper! "

This is an example of analogical reasoning.
