That's not necessarily true. We experience vision as a unified whole as well, but we have a blind spot as well. How would you argue that consciousness is a seamless whole and not just the illusion of one?
And in looking closely at electrical currents, is there really an entity or is it just a of collection independent electrons acting on each other?
Still, to look at the current and imagine that collective action creates a higher order entity (like the water in a river) is really poetic -- even if it doesn't turn out to be the case.
