Nominalism vs Realism

Anti nominalism argues that two individual objects can be the same in essence while still being unique individuals. This is a big one, and i think i'm right in saying that so much turns nn this third point. Realism states that eternal ideas or forms are real. A nominalist reduces reality to what we can see with our eyes. And as a result, we are now subjectively, assigningconstructing the world around us according to our observations.
