开一个（数学）玩笑

[testcaoy7]

由于用英语表达更容易理解，所以就用英语写吧：

Q: Why everything tastes like chicken?

A: Because "everything tastes like chicken" tastes like chicken.

Proof:

"Everything tastes like chicken" is a set. S = {x | x tastes like chicken}

This particular set ("everything tastes like chicken") contains itself because the set itself is an element of "everything".

Since "everything tastes like chicken" (as described), "everything", including this set, has to taste like chicken.

Hence, "everything tastes like chicken."

Q.E.D.

Disclaimer: THIS IS A JOKE.

In mathematics, set "S = {x | x tastes like chicken}" obviously doesn't contain itself.

Why does the set contain itself? The set itself is an element of "everything", but it doesn't satisfy "tastes like chicken".

@re2ikotr This is a joke. The fun lies in the play of words...

Bc we can using your proof to prove that “everything tastes like beef”. And beef doesn’t taste like chicken. s there’s a paradox. Your proof doesn’t make sense.

@ftfunjth "Chicken" or "beef" is irrelevant. In naive set theroy, "labeling" doesn't matter.

@ftfunjth #3 or beef tastes like chicken and chicken also tastes like beef. They have an equivalent relation.
