2 + 2 needs to equal 17.

That's too didactic. It needs to equal whatever it wants to equal. Otherwise you're a racist or a sexist or something ...

17 is fuzzy. I can mean whatever you want it to. For example, a tiger-stiped panda. I like those.

[Fred Hayek]

Well then
2+2 can equal 5
and 2+2 can equal 3,
and 2+2 can equal 4,
and then 2+2 can equal 3, 4, and 5 at the same time.
When you accept that, Winston, you are starting to get well.
