Universals are without matterspacetime. Particularly obvious is the timeless nature of universals. The fact that “they” are unchanging means they also must not have spatial location, for if they did they would be particulars. And by not being particulars they are without substance.

Universals do not exist in reality.

But “where” then do they reside? To hold a universal is for a matter-body to have such a thought. Universals are a process of the body. Someone or something must hold on to the conceptualization of universals.

When that body ceases to hold those thoughts, it either has forgotten them or has perished.

You do not find universals in reality. They mapped into the reality by a body in reality.
