Anyway, as for cognition thingies, something has to be said for complexity. Author Heinlein dealt with the computational theory of cognition in the story "The Moon is a harsh Mistress." In it is a computer maintained by a practical guy named Manny, short for Manuel. Anyway, he is responsible for all the maintenance and upgrades to this central operations computer on the Moon. And one day, the computer "wakes up." That is, becomes self-aware. And orchestrates a revolution on behalf of the humans who are being oppressed by others. Complicating this is that part of the Moon is also used as a penal colony, akin to the initial developement of Australia. The point being, at some point, reaching, as it were, a critical mass of connections, sub programs, including self-correcting ones, the computer became aware of itself as an entity, the difference between I or me and the rest of existence. And so the philosophical question was also asked in that story and other later stories involving that one (later Heinlein books developed a world and time line history based on alternate universes and time travel) was that couldn't this event in the computer also explain Man's sentience? Or that of any creature that reaches a certain level of complexity? And it is complexity, rather than physical size. Dogs, regardless of size, act the same way. The Chihuahua acts the same way as the Great Dane. Descartes posited "I think, therefore, I am." But it begs the question of when did I think and become the "I" that I am?
I am excited that others are trying to hunt this down through neurons. Will it lead to a shape and "snapshot" of a "soul"? Who knows? First, we have to define soul and what it exists of. I think it's a good place to start.
Of course, some of our observations may be informed by our perspective. Similar to the effect in quantum and newtonian mechanics of bringing an electron microscope to bear on an electron. The em field of the microscope will align the spin of the electron up or down, for simplicity. The observer affects the observed. I don't think we can escape anthropromorphism. It has to be explained in terms we understand from our experience. We can't view from an extra-human viewpoint because we are human. Even math is but a human language to describe something. But this does not deny ToM in Man or other animals. Dogs do know that we have a valuable perspective different from their own. And they understand this in a doggy way which, at times, appears symbiotic to man.
In the same breath as dogs do cognate, it is not always in ways expected by Man. That is, a dog does not have to think like Man in order to be able to think and this was my greatest contention with theories that paint dogs as unthinking creatures simply because it only appeared that their "thinking" was different from man, which is logically an impasse. If dogs can't think, then there is no difference between them and man. It's akin to the logic sequence that if you believe in the Devil, you must give credence in that construct to the existence of God. Likewise, if we say that dogs think differently than Man, we are admitting that they think, in general. ("It's not that the bear dances the waltz, it's that the bear dances, at all.";)
And because a dog's thinking is not always represented well or as "loft" as man idealizes his own thinking, doesn't mean that dogs don't have complexity and deeper thoughts. Dogs do mourn loss. As so eloquently and honestly portrayed by Burl's story. One might say that it is merely a neuronic level reaction to the loss of a smell that has been accustomed to being around and the change in the environment induces a "stress" until the change is assimilated. To me, that is like footprints in the sand. These are mechanical traces of greater complexity.
And I don't think the dividing line between sentience and non-sentience is whether or not a dog speaks a human language. Dogs do have language. I haven't quantified it but I can tell the differences in Shadow's barks. There is the normal visiting and carousing with the neighbor dogs. There is people and pets walking down the street bark. And then, there is the human visitor nearby bark. In addition, there is the alert bark. They are subtley different. Perhaps I am attuned to them because of my involvement in music. Because languages are like music to me.
