Consciousness is that by which the activity of mind becomes experience. To say this seems to imply that mind exists prior to consciousness and that the latter is superadded to it from outside, as it were. This is basically the naturalistic understanding if we add that the consciousness is itself an 'emergent' property of mind at a certain level of complexity. This explains the phenomena of degree of consciousness, the scale from automatism to fully awake and self-aware. It also allows for mind to take account of consciousness rather than simply be observed by it. The error here is to regard consciousness as a kind of thing, a factor which can be present or not. The consciousness that you would put in place of this, self-grounding context of contexts, say, should not be an improved version of this idea.
