LoveUni, you think everything is clear cut - no, not everything.
But it's important not to muddy the waters at every possible opportunity. Otherwise no conclusions would be reached, no consensus achieved and nothing would get done.
If philosophers spent all their time arguing over words (the tools of philosophy) and their definition or appropriateness, no issues would ever get thought out and resolved. You'd end up with philosophers arguing amongst themselves about whether this word or that word constitutes a micro-aggression.
BTW Thanks for the link, I'll read it when I have the time.
"Evolutionary history suggests that life involves a range of co-evolving hierarchies, and that non-life and life share a huge and biologically significant territory that buffers and makes more complex any account of either." - this may be so, but we're discussing whether rocks are conscious. There are also some long, fancy words in that quote. Let's chuck 'em away and talk in plain English where possible.
As far as anyone can be certain, only living entities have consciousness - e.g. I am living and I have consciousness right now as I'm typing out this post. I assume the same to be true for you and other posters.
