You said (to Atheos), "[Cows] have brains and heart beats and those brains are much more complicated than your average 1 year old. So what is your last criteria [for privileging human life over animal life], other than homo-centrism."
I said, "That criterion suffices for me. (Why) do you find it lacking?"
You responded, "The position is refering to brain activities. And cows have that. So the question returns to you, why is it ok to kill cows for food?"
With respect, it actually doesn't. Homo-centrism suffices for me to explain why it's ok to kill cows for food. If it doesn't suffice for you (and I think it doesn't), it remains an open question as to why it doesn't, eh?
In fairness, you did go on to provide something of an answer later, viz. "you can't just look at DNA and say: 'this is human DNA, and that is cow DNA' because they are the same letter, packaged differently, for sure. But even how the letters are packed away ( the chromsones, or chapters ) are not something which makes us uniquely deserving of life.
If it is other things, than using DNA is like using colour to discriminate against slaves. Ie just an excuse."
With regard to "how the letters are packed away," I certainly don't think there's some amazing quality in the human vs. bovine DNA sequencing itself that confers additional special rights on humans and comparatively few on the cattle (i.e. Question #3 from my prior post). Where the regular difference in DNA coding has significance is that it allows us to distinguish humans from non-humans (i.e. Question #1 from my prior post). And if, under homo-centrism, humans DO have an elevated/expansive spectrum of rights that they deserve, and that cows do NOT deserve, it is quite important to know who is human and who is not.
As for the question of what actually privileges humans, I was a little surprised to see you come around to the position that humans actually do deserve special privileges: "The qualities of what makes us human are important. That we feel, that we are self-aware, that we are capable of compassion and empathy. That we grow and learn from our mistakes, our consciences. All of these things are important.
Do you take the position that a 1 year old baby has more of these than an adult cow?"
While all of these things may be important, I can't see why they are important other than that they make us different from non-humans (and this position itself is, I think, potentially dubious). Why do you think they make us uniquely deserving of life and care?
As for my own reasons for homo-centrism, I will go with the same response I gave to pangloss back on p. 4 of this thread:
Homo sapiens is a select species with dignity and rights that do not inhere in any other species. Membership in the species is sufficient to confer these dignity and rights without additional appurtenances such as self-awareness and rationality (as traditionally understood) [and, I would add here, compassion, empathy, and neighborliness] being necessary. Other species, meanwhile, are quite literally sub-human.
My reasoning stems from Genesis 1.26 "Then God said, 'Let Us make man in Our image, according to Our likeness; and let them rule over the birds of the sky and over the cattle and over all the earth, and over every creeping thing that creeps on the earth.'"
[On the point of the morality of eating meat in general, there's Genesis 9.3: "Every moving thing that is alive shall be food for you; I give all to you, as I gave the green plant." I don't think this can be read to suggest that all methods of producing meat are necessarily moral, but it does at least point out that using animals for the purposes of feeding ourselves is very much within the pale.]
