Metaphysically.
What that means is, we have the same potential. This is in contrast to the Chain of Being, which asserts that kings are metaphysically superior to others, the Ubermench concept, and alturism (both of which say some people are destined to serve, and others to be served).
Two problems here.
One, this isn't a metaphysical claim, it's a physical claim. Two, it's also wrong. I don't have the potential to win footraces that Usain Bolt has. Someone with Down Syndrome doesn't have the potential to win medals in gymnastics at the Olympics.
What you're actually trying to express is an ethical or meta-ethical claim that all people
ought to be
treated equally.
Just as therre are plenty of societies that exist via slave labor. Does that mean that you don't object to slavery?
No, it means that your empirical claim that there is something wrong with such societies is unsupported.
Once again you are trying to justify what needs to be an ethical claim with a spurious and also incorrect empirical claim.
You're twisting our words. To call respecting rights a duty is a perversion of both concepts. Before you ask, the perversion is this: in a deontological ethical theory you are obligated to do your duty even if you are utterly alone. Rights, in contrast, are only applicable when you interact with others.
You don't actually know anything about this at all, do you?
Some deontological moral systems prescribe that you do your duty even if you are utterly alone, like Kant's, but there is absolutely nothing inherent to deontological systems that requires this. An entirely rights-based moral philosophy is perfectly possible and would be deontological.
Further, the proposal that it's a perversion of the idea of duty to call respecting rights a duty is completely daffy. The mere existence of a right implies the existence of a corresponding duty to respect that right.
And as for the perversion of rights, to say you have rights but that other people aren't obligated to respect them is to say, in fact, that you do not have those rights. A right that need not be respected isn't a right at all.
Well yes, but a right that need not be respected is a right which doesn't imply a corresponding
duty to respect it. You can't have rights without duties, because a right to X is a duty that others not stop you from getting or having X. Hence it's nonsensical to claim that it's a perversion of the ideas of duty and rights to say that you have a duty to respect rights.
I told you: They originate from the fact that you're interacting with equals. If you're not interacting the concept of rights doesn't exist, and if humans weren't metaphysically equal they wouldn't be what they are.
I don't expect you to actually take any of this on board, because you're an Objectivist.
I just want to make it clear to bystanders that in terms of actual moral philosophy, this guy Dinwar is babbling word salad. He's using the terms philosophers use but he doesn't understand what they mean and what he's saying makes no actual sense.
It's possible that in Objectivist-land the words he is using mean something totally different ("metaphysical" means "meta-ethical", "duty" means "poo-poo head talk" and so on) but inventing your own special, incompatible meanings for what is already specialised jargon would be incredibly perverse.
