I think that the terms "sentient" and "sentience" is misconceived by many here from what I could gather from this and other discussions (topics) — Alkis Piskas
(the following applies to the remainder of that section of your post too).
That's fair. I guess I would stipulate the difference I outlined previously for two reason:
1. That seems to be what most philosophers of mind take to be the difference between the two; and
2. It makes it much easier to talk about awareness over consciousness (or, as a higher level of it).
So, in with your definitions in place it would be very hard to see how a fruitful conversation about hte
difference between a human and plant viz. what type of perception constitutes whatever we want to call the 'human' level of consciousness vs a lower, plant-like level. I think sentience, as used to enumerate an actual rather than speculative self-awareness (something i really don't think a plant has) solves what would have been a linguistic problem.
Regarding the related link you gave to the Plant-Consciousness essay - I can't say much about it. It's not referenced, seems to make some pretty wild leaps:
"A bean plant, being fed upon by a spider mite, can
analyze from its saliva just what type of spider mite is feeding on it. It then will
craft a specific
pheromone, releasing it from its leaf stomata as a volatile chemical into the air. That pheromone
will call to the plant the exact predator that feeds on that particular spider mite"
these appears to be inventions of hte author - we have no reason to think this isn't a mechanistic process the same way many of our autonomic processes occur. There's clearly no 'thought' in it. So, the contention isn't supported by the article itself. We also get sections like this:
"Depth analysis of plant consciousness since the turn of the (new) millennium is finding that their
brain capacity is much larger than previously supposed, that their neural systems are highly
developed—in many instances as much as that of humans, and that they make and
utilize neurotransmitters
identical to our own."
These are almost all demonstrably untrue claims. Plants do not have brains, as a start point.
But certainly they must have a certain kind of sense, i.e. they must feel something, othersise they coulnd't perceive — Alkis Piskas
I don't think this is the case. I think because of your broad use of 'sentient' you're importing a necessity that isn't present. A plant need not be 'aware' for it to mechanistically react to stimuli. If it could, in fact,
choose how to react, then we get some infernce of analysis whcih would require some debate around feeling. I don't quite think the current explications can allow for that inference. I would also note that VFT do not know
whether it's a fly. They also snap at fingers, large dust, small rocks etc.. etc.. It seems to be a triggering event, not a perception-driven event.
I see that you took the VFT proposed experiment seriously! :grin:
Well, a appreciate a lot a fruitful imagination like yours! — Alkis Piskas
Heh, that's definitely going to be my schtick until I'm a graduate student LOL.
So, I believe we can safely take this element out of the equation. — Alkis Piskas
Fair, and I agree. I suppose here, we're leaning toward that cognition isn't involved, so feeling can't follow. Unsure if that was your intention with this though!
I don't think, either! :smile: — Alkis Piskas
As above. I think this is nearly a fatal flaw in the theory that a VFT is sentient. But again, with your defintions in place, nothing we've discussed would lean one way or the other!! I just prefer the definitions i've used as they make a fairly good, albeit imprecise, heuristic for judging the mental faculties or one or other being.
