Wow. That left me baffled. You're filtering your philosophy according to what affects you, really?

I mean there are some interesting ideas in there, but no elaborate argument matters when it is circular and refusing the very base it stand on.

The claim is that circles are a property of the universe. That's not a knowledge claim, that's a claim about truth.

> exist outside our universe

I never said that. When you monomorph a C++-template, it exists in the final binary. It of course won't be a single thing, it's existing among multiple things. But that doesn't mean it doesn't exist.

> Your ontological and epistemological beliefs are about to converge on anti-realism.

Based on Wikipedia about Anti-Realism: no. Something must be logical AND exist to true, otherwise it's merely logical imagination.

> It doesn't really matter if Pragmatism is 'Truth'.

That sounds like you bend your perception of reality to match your belief. And when it's inconvenient you say it doesn't matter.

I really think there is a fallacy here, can you please refute that?
