In Franz Wright's remarkable poem "Robert, Cat" a man feels his cat bestows "unqualified forgiveness." This may just be the speaker's persona, of course, not the author's view, but I feel like disputing it anyway, since lots of pet owners do hold this notion that animals have feelings that are just like ours, only deeper, purer, unsullied by ulterior concerns. The thing is, we really don't know what animals' mental states are like. Maybe Robert the cat doesn't even have any clear memory of having been mistreated by the speaker, if, indeed, he ever even had any sense of mistreatment in the first place. Heck, I can't even count on my own spouse bringing the same frame of reference to any interaction that I bring to it, so how can you make that assumption in an interspecies relationship?
If I step on a fire-ant nest in the yard, and get bitten, I don't harbor any feeling of resentment toward the individual biting ants. I don't think, "You little bastard, you're the one who did me wrong." In my head, a vague sense of menace and annoyance surrounds the whole anthill, but that's it. Suppose tiny robot servants carefully plucked just the "guilty" ants from my body and saved them in a separate petri dish, I would have no feeling about those ants that was different from any other fire ants.
That's why I've always thought hell was such a crazy idea. That a supposedly omnipotent being would bother to punish such comparatively insignificant consciousnesses at all, let alone infinitely, is preposterous. Or to love them, either, in any but the most abstract and not especially gratifying way.
Nope, hell is invented by humans, for humans, in a paroxysm of masochism or hate.
I'd put the whole Wright poem up here, but I don't want to run afoul of copyright. It's worth a look.
