What I am trying to ask in particular is how do we know what is conscious and what is not just because something moves, breathes and interacts with the environment doesn't mean it is necessarily conscious take a tree for example it does all those things and even reproduces we consider it to have a life but not consciousness (in the traditional orthodox sense - not ontological). How do I know my fellow humans are conscious, is it because of this sense of empathy(sonder) or is it just because of similarity to one's self (self-realization and consequent realization of similarity) but is that enough to conclude something is conscious? For all you know an automaton with human skin might be similar to me but it doesn't mean that it is conscious, right? Is self-awareness a necessity for consciousness? Can something be self-aware but not conscious? Say if a human is devoid of any and every sensation and activity, can one still be considered conscious?
What about for animals? How about babies, when do we humans start to have consciousness? If consciousness is like a switch then at what age does it turn on but if it is a gradual progression when do we say we are conscious (how do we know this and realize), or have we always been conscious if not then maybe we were never conscious to start with?
With the above swarm of questions being the base, now my follow up will be: Are each of our cells conscious (because it is alive - if life and consciousness are mutual), is every nerve fiber conscious and the amalgamation of the consciousness of each nerve fiber and synaptic connection gives rise to a greater consciousness i.e., our consciousness (the brain's consciousness)? Then if we consider each cell to have some sort of consciousness then maybe other single celled organisms also have consciousness. This makes me think, Is consciousness and life mutually inclusive? Because consider something vague like a virus, it has this sense of duality in regards to its state of life, when outside a host no signs of life but inside it gets to replicate and share information. If we accept that life and consciousness are mutual then does that mean a virus loses and gains consciousness depending on environment or is it the case that it always has consciousness? If that is the case then, do all other non-living things have consciousness? and if that is the case does an atom or building blocks of matter each have their own consciousness? Do space and time also have consciousness? Is everything (i.e., reality) just one big conscience?
Extra: Is existence, life and consciousness necessarily mutually inclusive?
