I think this is also what some meditation based philosophies are trying to teach. That is, they're saying something along the lines of: you are in one way everything at once, but you are not any of the things you think you are. They spend a lot of effort trying to teach people, essentially nothing. Not just the label "nothing" but something like a deep realisation of the concept.
My main problem with this philosophy is figuring out why we're conscious of a very specific subset of things at a time. Does the brain create a kind of nexus where several items of complex information are available in a small physical, and that makes it easy to be conscious of these things at once? But what limits it?
And the other problem is the link between consciousness and action. Most actions seem like a product of cause-and-effect.. but at the very least it seems that the existence of consciousness is making us talk about consciousness.
