Act one, in which bashere sees racerx’s rant, and raises her a couple
Wow, racerx, you pegged all of the issues that I thought would have prevented us from discussing this. I still think we are on opposite sides of a divide that can’t really be bridged, but at least we aren’t shouting at each other across it.
Act two, in which bashere tries to sound like a reasonable person
First off, I wanted you to define “love” not to trick you into some epistomological trap, but to make sure that we are talking about the same thing. For instance, some people can define love as a transcendental state in which the happiness of another is more important to you than your own. Others define the same thing as a brief serotonin-induced state followed by pain and heavy drinking. You seemed to be implicitly defining love as “an emotion only creatures capable of demonstrable abstract thought are capable of”, in which case I would be an idiot to argue that dogs love their humans. Please accept my apologies if I did look like I was just trying to score debaters points. More on this in just a second.
Act three, in which bashere starts to sound a little strange
You state, correctly and inargueably, that communication has limits, even when conducted between intelligent members of the same species. This is one of the things I find interesting about dogs and people; I would respond that a form of communication exists between dogs and humans that teaches the moderately observant person interesting and insightful things about the nature of communication. I can’t really seem to express what these things are, mainly for fear of, err, sounding insane (note to self; probably too late) but clearly the fact that we can interact with dogs so well can be considered fascinating by a reasonable person.
Act four, where people really start to worry
In further answer to your OP; I think it would be an interesting and legitimate line of speculation to consider the, for want of a better word, evolutionary advantages (although I doubt it is genetically related; perhaps some one else can supply a better word) of the relationship between humans and dogs. Dogs were domesticated somewhere between 20,000 and 50,000 years ago (depending on who’s counting, and the exact definition of domestication). At the time, we were still struggling our way to the top of the food chain. I would argue that small bands of humans with domesticated bundles of teeth, muscle, and claw had a better chance of survival than their unaided brethern. I’d also argue that those canines who befriended humans had a better chance of survival than their undomesticated brethern. I would further, and finally argue that this relationship is fundementally different than the relationship have with other animals (with the exception of horses). I think it an interesting line for WAGing to consider that those people who like dogs are the, hmm, intellectual(?) or spirital (?) heirs to the people who first formed the “deal” between dogs and humans. I would like to point out that whether or not I am a) insane, b)an idiot, or c) both, is also a legimate line of reasoning.
** Act five, in which a summary is attempted**
I would suggest lots of things about dogs that are subject to a debate that we probably can’t resolve do to epistemological issues. I would argue, for instance, that dogs are self-aware, and are thus capable of “higher” emotions. I would argue that they feel something that can best be described as love (even if they sometimes feel the need to express it by knocking people over). I would argue that dogs can teach people a lot; possibly not quantum mechanics, but certainly interesting things about communication, about societal behaviour, about self control, and certainly about the best place to lay in the sun on beautiful days.
Act six, in which the whole mess finally comes to an end
I’m not a nature-loving freak who places animals on the same plane as people. I support animal testing. I eat meat and wear leather. I have been spotted on the SDMB defending Bush. Clearly, I am not an overly sentimental person. But I think your statement that “I realize that many pet owners blur this barrier between human and animal.” misrepresents the case. There are profound differences between the feelings a pet owner has for a human and for their pets. Because the deepth of those emotions is similiar, it is hard to come up with words to convey the emotions to non-pet-people with out resorting to analogies - “he is like a child to me”. Sorry I can’t explain it better than that.
I’ll stop typing and post now. The nice young men in the clean white suits are here for me.
