You believe - as do I - in objective moral truths, which you frame as "natural rights". These, of course, imply "natural duties", because a duty (obligation) is simply the corollary of a right: if one has a right, then others have a duty/obligation not to violate it.
Yes, another free will -- a person -- has the same claim to his life, liberty, and property I have to mine. It's immoral for either of us to treat the other as property or resource or plaything.
However, you appear to believe that you have no moral obligation (at all, it turns out) to cows - or to most (any?) non-human sentient beings.
Becuz most if not all of that
feeling life are not free wills -- not persons -- and have no moral claim to themselves. They're
meat. Truly they are resources to be cultivated or squandered. We can treat them humanely but have no obligation to.
I don't see any morally-relevant different between human and non-human sentient beings with regard to the natural rights you enumerate (the right to one's life, liberty, and property). I am thus challenging you to justify the existence of morally-relevant differences.
I just did.
Insofar as harm is caused by pain: no. Perhaps a better way of framing it though is that (s)he (along with all entities) has the right all along, but it will simply never become applicable, just like the right to one's own property will never become applicable if one never acquires any property in the first place.
So Jane, who is insensitive to pain, has no right 'not to be harmed where that harm can be avoided or minimize'? Or she has the right, but it's moot cuz if I stab her in the thigh with a steak knife, she can't feel it?
There are other harms-of-suffering than the infliction of physical pain though, including the infliction of emotional suffering, the suffering of deprivation, and the suffering caused by thwarting harmless preferences, wants, and desires when this is not to prevent a greater harm. The last item in the list suggests that the second attribute I listed can in part be considered to be a sub-category of the first:
All this is perfectly in keeping with free wills. None of it applies to bio-automatons.
I'm not sure what you mean here, especially what is "called for" and why. I could guess, but I'd prefer not to put words into your mouth.
Feeling is not enough. With
meat, feeling is purely an electrochemical event. It's the equivalent of a ERROR message on your computer. Literally, there's no one
there to experience the feeling, to contemplate it.
In the context of killing animals so that you can eat them, their capacity for or subjection to moral "judgement" is not relevant. All that's relevant is the moral consideration they're due; the moral obligation we have towards them. In this context, the proper starting place is to ask what attributes of a being entitle that being to moral consideration, and why. I've described what I think are the two most important ones above, albeit that, as I've noted, the second is in part a sub-category of the first. It's strange to me that you describe this as working "x)", especially given the context in which I challenged you.
They're due none; we have no moral obligation to them. Well, I wanted to talk about
what is a person? and you poohed-poohed that as a fruitless debate over a definition and its applicability. You said such a discussion wouldn't get to the core of things. And here you are, now wanting to ask and answer
what is a person?. I've explained why those two don't work. I was mockin' you over your 'working'.
As for free will, two points are worth making: Firstly, I see no relevant differences that would lead me to conclude that non-human sentient beings lack free will whereas humans - including myself - possess it.
So, define free will, as you imagine it to be.
Secondly, even if I did, it does not seem to me to be a relevant attribute: a being can suffer or be harmed regardless of whether or not it can freely choose how it responds, and the capacity to suffer or be harmed is - in my view - the primary morally-relevant attribute.
As I define free will, it makes all the difference in the world.
Let's say that some evil scientific genius implanted in you, henry quirk, an evil device which took control of your thoughts whilst leaving you with the illusion that you retained control, and without your knowing. You feel just the same (except that maybe you have some vague intuition that something's a little odd and not quite right), but you actually no longer have free will. Would it then be morally permissible to steal from you, force you to work without compensation, torture you mercilessly for days, and, finally, pour petrol over you, ignite it, and burn you to death? If not, why not?
Of course not. I've been violated, not nullified. My moral claim to my life, liberty, and property remains. I am a free will.
Roberta the hen, it has no such claim, has no capacity to levy or receive moral judgement, cannot be morally violated. That there chicken is no person. It's
meat.
