The definition in those dictionaries is vague but consistent with what I said.
Well, sure it's consistent with what you said, but that's not the point. The point is you are adding stuff on to the definition to help your point. You could add a lot on to the definition and still be consistent. The difference I don't think my interpretation is adding anything on, but rather taking it literally.
But you're looking up the term in the wrong sort of dictionary, those are common language dictionaries but "sentience" is a technical term in philosophy (and science) so you need to look it up in the Oxford dictionary of philosophy or something similar.
I've debated this a lot and have never heard this before. I don't have a copy of that dictionary readily available. Do you? The common language definition seems to match the definition used in biology.
That depends what you mean by "self-awareness".
How? I mean, it means awareness of ones self, that's it. Can you give any supported definition of self-awareness that would allow for an entity to not be aware of what is happening to them, barring states of unconsciousness or the like?
Using the roomba again as an example, it has 'experiences' but almost certainly has no sense of self nor awareness of it's self.
As I pointed out above, you wouldn't use the dictionary definition because its entirely vague.
The problem with using your definition though, is that there is no source for it, except maybe Singer's or other authors writings. As I said, it's a definition vegans seem to have collectively agreed on, and I've never found a source for it.
You can dislike the dictionary definitions, but you can't expect me to just take your definition at face value. If you have a source for a more context specific definition, I'm happy to use it. Until one can be provided (and I am trying), I would prefer to stick with the common language definition, which I think is reasonable.
Very few scientists argue that insects are as a whole are sentient.
Everything I've read on the subject indicates that the consensus absolutely is that insects are sentient, with the caveat that sentience is a scale, that they are not capable of reasoning etc (which isn't required by the base definition of sentience anyway).
There is a study where ants passed a basic mirror test but that doesn't mean they are self-aware and its never been duplicated, assuming the results are true the far more likely explanation is that its just a simple heuristic. Ants have very poor eye-sight and their brains are tiny, ant behavior is based on a variety of mindless heuristics that result in emergent properties as a group. Ants have a grooming routine so there is probably something about the dot that triggers it.
I had thought ants passing the mirror test had been replicated? Huh. I agree however it was not evidence of self-awareness and some other explanation is more likely. Bees are a much more interesting case as they display emotions, seem to have memories (IIRC), and by all indications are self-aware and sentient, by any definition.
But this is another issue, like sentience we have no good test for "self-awareness".
Right, we don't just have one single test, but we have a variety of tests we can do, and a variety of behaviors we can observe that can give us a pretty good idea.
This is only a problem when you're using the colloquial notion of "sentience", the notion used in philosophy (and science) is far more concrete.
So, while writing this reply, I managed to get access to "The Cambridge Dictionary of Philosophy 2nd edition", which uses the word sentient in a number of other definitions, but does not provide it's own definition of the word, which means it is using the common language definition. The science dictionaries I found online also match the common language definition.
Cambridge is a pretty reputable source, so it would seem at least in some cases it is the common language definition of sentience that I provided above which is used in philosophy. I will continue to try and get access to the Oxford dictionary of philosophy, but I somewhat expect the same result.
Though I agree, when the average person talks about "sentience" (including vegans) what they are talking about varies a lot from person to person and there is little clarity. And this creates a mess when they try to align it with the more concrete philosophic/scientific notion. For example, for them "sentience" mean imply a sort of sapience but when the scientists talk about sentience that isn't what it means at all. This sort of equivocation causes many vegans to falsely believe scientists support what they think about animal cognition.
I've absolutely encountered this. I really do think the star trek wikia page, despite being star trek, has one of the best explanations of the different definitions of sentience and all the ways the word is used. In my experience many vegans arguing for sentience argue as though sentience was synonymous with higher level consciousness and self-awareness, which threw me off when I first started debating and researching the vegan position.
