It's under the tag philosophy
Usually for philosophy classes you required a background in geometry
Legend goes that Sokrates made that a rule for his school ( or something like that )
The whole concept of philosophy is based on the idea that there is only one wisdom.
philosophy is of greek origin and the plural means 'stupid, irrelevant'.
If you believe in more than one wisdom/truth then it's not philosophy.
TL;DR: Can't argue with someone who thinks 2+2=5.
Then your knowledge is way advanced compared to mine :)
