An animal's life might end in the slaughterhouse and a human's in a graveyard. That's the way the cookie crumbles. We make decisions based on a lot of things, convenience included. We decide the purpose of cattle while the rules are looser for people. There is no objective spiritual price for the animal industry; it's just a matter of opinions, and "enormous" feelings. Feelings, experiences, qualia don't operate on a measurable level so it doesn't matter.
Nothing here provides any rationale, or metric, or basis for morality at all.
The first half of this paragraph boils down to "that's the way it is", which is a complete non-argument. Yes, I know it is. Are we supposed to base our morality around how stuff currently is? War currently happens, so war must be morally fine! Let's start more wars!
In the second half, you're saying that because there's no objective spiritual "price", we should be able to do whatever the fuck we want. Uhrm,
no morality is objective. There's no "objective spiritual price" to the murder of a human being, either. But a reasonable, functional, moral person should be able to come up with a coherent moral philosophy nonetheless.
The emergent properties, higher cognitive functions that humans develop, are the basis for a hierarchy among species. Therefore we are above animals at any point in time. The past and the future included.
So, you're basing it on intelligence, then. But you also seem to have bizarrely concluded that the
potential for future intelligence is more important than
current intelligence. Let's see how far that logic takes you: a human egg & sperm have the potential to develop into a being with these "higher cognitive functions". Are we now in Monty Python "every sperm is sacred" territory, then?
I don't believe non-realised potential should somehow be deserving of greater protection than actual, current intelligence. I think that's kind of grotesque.
On a side-note, these cognitive functions are hardly a binary. Animals do have sophisticated cognitive functions, just not as highly developed as (most) humans. Animals can use tools, they can grieve, they can remember over the course of decades, they can form complex social structures, they can form long-term committed loving bonds. And yet you seem to believe that the gulf between us and other animals is so great that despite all of these clear cognitive abilities, our mere
momentary convenience is more worthy than their lives?
Your moral system isn't valuing cognitive functions at all. That's a window-dressing rationalisation.
I wish people would consider abortion neutral. Who knows, maybe I'm the only one? Logistically I think it can be neutral (Done early enough there should be no long term health effects and what have you. edit: Like against any "if you're not having this one you can kiss your fertility good-bye").
Yet you've outlined a moral system above which would convey enormous value onto "potential", which seems clearly at odds with the idea that it's "neutral".
