My own answer doesn't match the thread quoted in the quoted post.
So I answer here (I'll leave my own dim views for another time).

When I was a university student of mathematics, we studied The One True Philosophy, namely, dialectical materialism (that was on the east side of the Iron Curtain).
To illustrate with a joke:

A student leaves an examination in philosophy _very happy_, shouting:
"I failed! This is great!"
The others waiting outside don't understand.
"Of course it's great! The student before me was _arrested_!"
