Is There a Unity of Consciousness?

i'm not confident that it's a reliable extrapolation yetut that seems to me to be the problem, is differentiating between whether or not consciousness is being duplicated or mimicked. And i think, tt, that would be a hard frog here to cut. Most of us only have one consciousness. What's the deal here? Why do we display a so called unity of consciousness? It's an arian philosophy. Going back a very long way, it's mentioned by plato and aristotle, and later on by a kant ah.
