and then you go on to say
Animals and plants are not volitional creatures, and therefore are outside of the realm of morality
as if these two things were connected. They are completely unrelated. Let's look at that first sentence again, word by word.
"The basis and foundation of
all morality is the inherent value of human life."
By using
all, you say that morality has no root, no basis, in anything
but the value of human life. Therefore if the question relates to the value of human life, it is a moral question, otherwise it's not. That's exactly what you said. I found that unbelievable, myself, and was surprised you wrote it, but it is what you wrote, so I went with it.
"The basis and foundation of all morality is the inherent
value of human life."
By using
value, you refer to the quality of an object that makes it desired by something which, itself, is capable of asserting a value. (Magnets may act as if they value iron, because they appear to desire it in a measurable fashion, but we don't call that value.) The simplest (but not only) test of value is "if I destroy it, does that matter?" If I crush an ordinary marble that I own, but do not care about, the act doesn't have a value-property, because the marble doesn't have value.
"The basis and foundation of all morality is the inherent value of
human life."
You didn't even tie it to human existance or experience - you just said life. That argument makes sense if you're making a materialist's pure appeal to blind, biological, evolutionary forces, because those come into play only on life/death questions - evolution doesn't care if we're happy or have interesting experiences, in fact a little misery might spur some extra reproduction, and that's all that matters on the evolutionary level.
"The basis and foundation of all morality is the
inherent value of human life."
We're engaging in something like Descartes "radical doubt" questions here. Nobody gets to claim anything is inherent without pointing to some evidence. As far as I know you haven't advanced a single argument that allows you to claim anything has value at all, let alone inherent value, which is something of a contradiction in terms to begin with. We both secretly agree that humans have value, of course, it's just that neither one of us has demonstrated the reasons yet and until we do we shouldn't be setting it up as an axiom.
So nothing you said has anything to do with whether animals have volition, or animals at all. My point was that cruelty (which involves suffering in the recipient, which arguably decreases the recipient's perceived self-value, if there is such a thing) isn't wrong according to your statement, because no human life is diminished in value, and you said that's the only way morality can apply.
Now I suspect that's not what you meant - I get the impression that you aren't expecting me to deconstruct your sentences with this kind of rigour - but it's part of my nature to do so and believe me, inquiries into truth and falsehood have to be conducted with finicky precision, or they quickly turn to vague battles of contentless words, used only for their connotations, not their meanings. And I won't do that, having seen far too much of it.
So in the interest of not talking past each other, I have to ask that you agonize over your sentences.
I agree that the phrase "value of human life" is not a nonsense phrase. But that's because I have a framework which gives humans value; to wit, we are created by God and loved by Him, and that assigns value to us.
OK, now we are getting down to brass tacks. This is I am guessing the true root of your objection to my argument. I have of course heard this particular argument many, many times...
I wasn't advancing an argument. I was explaining that when I use a phrase like "value of human life", I do have a personal framework that makes it a valid phrase for me, but I'm not defending that framework yet or even explaining it. I'm only contrasting this to you, who have not yet advanced any claim of a framework that makes it meaningful, so I'm questioning if you have one. I'm sure you do, everyone does except for serial killers. But the "why?" matters.
What I have absolutely not done is claimed that my framework should be yours and given reasons why - in other words, I'm not advancing any arguments yet. I can't. I'm still trying to map out what we agree on, because without that there can be no common framework of discussion and we just end up slinging around contentless words.
You say we're getting down to brass tacks. I hope not. We're not at that stage.
I'm sorry if it feels like you're debating a robot, and at this point it might well. Grinding down into presuppositions is a loveless and sometimes dull process, but there's no other way.
In your context, the only thing that holds weight, the only thing that "feels right" and "seems plausible" is a religious explanation for morality
Absolutely and uncategorically false. All sorts of things "feel right" to me, and I've learned to ignore them when it comes to discussions, and I try to discount them when it comes to living. Feelings are all very nice but they aren't the basis of moral discussion; if they were, boinking my neighbor's wife could certainly become a moral act for me because I could certainly convince myself that it feels right. (Evolution would side with that feeling: more reproduction is all that matters, after all; it has NO other way to operate.)
The reason that I have settled on a religious basis for morality is that I find I agree with Francis Schaeffer: every other approach has collapsed and every philosopher who has tried it, while claiming to appeal only to reason and axioms, has failed. They all seem very logical but when you dig into the presuppositions they always make at least one little "mystic leap", something they claim is true that they can't lay a rational claim to, and don't try. You know when this happens because the definitions suddenly become vague and the connotation words start flowing. You did it yourself, by trying to sneak the word "inherent" into a sentence where, I promise you, it had absolutely no business being.
I trust Schaeffer's assessment: and so I'm going to find your own mystic leap. It's there somewhere. Of course you can shortcut the process by stating up front that you views are not fully consistant with your axioms and you accept that and that works for you. A lot of people do this and they are a lot harder to reason with, because they feel free to abandon reason as soon as they are cornered. At the risk of throwing a friendly stone at John, that's probably where he is going to end up. It's all very well to say your religion is reality, but when you start claiming infinity is your reality, a significant and unashamed mystic leap has occured.

By the way, I'll be up-front about this - I didn't become a Christian on the basis of a logical assessment of the facts, a refusal to take mystic leaps and a flaming refusal to balk at the conclusions. There are people who have done it that way, but I bet it's rare, and I don't expect to lead you to Jesus at the end of a logical tether. Even if that's possible, purely rational thinking doesn't come entirely naturally to people, which is why there are so few really good mathematicans and philosophers in the world. I got there via some personal experiences, and only then did I go back and start deconstructing everything in sight.
