So are you saying all true emotions are only based on physical reaction to environmental stimuli?
Sorry, dont buy it.
Sure all creatures fear being burned in a fire and run from the experience.
But, I suspect only humans can turn that physical fear into dread later - and enact prevention based on perceived threat of fire.
The former, dread, is an emotion; the latter, an intelligent response to that emotion. In that you are quite correct - the two are different.
While I do not know all the psychobabble, I also suspect that emotions are TIED to intellect - if you cant describe them, it's unlikely that you have them, so to speak.
I guess what I really do not attempt to do is to project human emotion and other capacities onto chickens because it SEEMS something they do is something I can relate to. I do admit that, in chickeny brains, there may be SOMETHING, an equivalent to emotions, that I can know nothing of. In turn, I wouldn't expect them to grasp our emotions or thoughts, either. So be it, I guess.
For me, that's good enough.
