Jeranism believes that maths does not describe reality.
What do the brilliant people of /sci/ think of this notion?
It depends on your definition of "reality." Do words describe reality? Do pictures describe reality?
I just looked up Jeranism and they're the flat Earth people. You would get much better answers if you actually asked the question yourself instead of just baiting for replies.
It's actually still being debated.
Can morals, justice, or ethics be described by mathematics, or in other words, quantified?
I personally think that yes, but since we don't even have a theory that describes the basis of reality coherently it is possible that it's not the case.
