Oh boy, this is really deja vu all over again. Let me try to cut to the chase.
My discussion of this, almost a half century ago, led me to coin a new term: taxocentristic. Think of it as anthropomorphic, but related rather than to being human, referencing any taxonomic clade you are focused on at the moment, looking out from the bias of your inner fish, or your inner mammal or your inner ape, as it were. Place one of those other taxons in the foreground and consider consciousness. Try to get beyond the limitation of the belief system that has been drummed into you and consider that chunk of consciousness that was part and parcel of each branch of the bush. What I came to think is that consciousness is not an exclusively human trait and not that we have more highly developed it than any other taxon, we have amplified the problem solving part of it. While at university I had a job as an Orca trainer. My whale was named Kenau and working with her changed a lot of my views concerning consciousness, as well helped to refine my ideas concerning the wrong-thinking inherent in the multitude of taxocentristic baggage we each (mostly) unknowingly carry. Anyway, I see consciousness as a continuum not a hurdle to get over, but I am not sure that I am ready to extend it to the non-living, except in the abstract or metaphorical as in Lovelock's Gaia.
