Wittgenstein. (Is this what Wittgenstein means?)

He has a terrible personality... He is a complete wonder in the world of philosophy!

His most famous incident is that after writing his first book (Tractatus), he felt that he had solved all the problems in philosophy. There was no need for the academic field of philosophy to exist anymore, so he ran away I went to be the principal of an elementary school...

And then I designed a house and so on...

Of course I came back six years later →_→ and completely overturned my previous theory hahahaha< /p>

Before he became the principal, it is said that he also taught graduate classes, but he did not lecture in class. He just pulled up a chair and sat in front and tried to persuade the students not to continue studying philosophy..._(:з」∠ )_

Similar to "I see you have very good bones, have you considered studying physics?" This kind of...

Later, they didn't dare to let him teach anymore... …

Still Wittgenstein. (A strange flower in the philosophy world)

It is said that after getting tired of teaching primary school students, Wittgenstein returned to the philosophy world, completely overturned his original ideas, and became a professor in Cambridge (it seems).

Then academic circles often invite professors from other places to give lectures and conduct academic exchanges. Wittgenstein always didn't like to go, because he felt that what others said was very wrong...

Once a famous philosopher Karl Popper was invited to give a lecture, and Wittgenstein went (it seems like Because he always doesn't go, it will have a bad impact on the school's reputation, because many people who come to communicate are directed at him).

Then while Popper was talking, he kept playing cards and threw cards at Popper (if he couldn't throw them at him, he just went in that direction), and he was all kinds of impatient.

Popper mentioned a concept during his lecture, which is that there are some moral principles that are absolute, and you need to abide by them no matter who you are.

This is basically completely opposite to Wittgenstein’s later ideas. Wittgenstein casually asked, “Can you give me an example? Which moral principle is absolute?”

Popper replied without thinking: "Don't throw cards at the lecturers who visit your school.

”

Wittgenstein stood up in anger and left, making the door ring =-=
