Absolutely correct, but that does not mean we’re not free to define rights in any way we want. You can define a right to freedom, but if somebody enslaves you, you can’t fulfill that right.
Utilitarians generally speaking are attached to something other than happiness, such as “happiness of the greatest number” or some such nonsense, which is all the worse off because utility is agent-relative, ordinal and not comparable between individuals except in the most speculative sense possible, and moreover its own principle is as in much need of proof as that of any other moral system. You could say you’re a eudaemonist, but that does not necessarily mean you’re a utilitarian unless you accept the system’s additional commitments.
It means that morals are relative. Disagreements on moral issues cannot be compared to disagreemments on scieitific issues, because science operates with quantifiable objects that provide absolute answers.
Well, we oppose anyone preventing anyone else from pursuing their own peaceful happiness. So rights withholding is something libertarians are very much against.
Fair enough. But generally, humans are capable of rational analysis. Animals are not.
Utilitarianism is in need of proof, but I start by observing that all beings seem to prefer happiness to suffering. I cannot prove this, but it’s the only rationale.
I think slavery is wrong, not because it prevents the freedom of a rational being, but because it causes suffering. Therefore I also think harming animals is wrong.
Then you might as well say you’re a eudaemonist (or better yet, hedonist - in the philosophical sense) and avoid attaching yourself to all the extra baggage utilitarianism carries with it.
Really, the fact that some people are slave drivers doesn’t mean that slavery is justified. Rather, slave drivers use violence because slavery is not justified. If slave drivers could justify slavery and ‘convince’ their slaves that they are to work ‘for free’ then it wouldn’t be slavery, but some sort of voluntary (if absurd) arrangement.
Maybe mathematical truths don’t exist either ? They are constructs of our brains…
He’s saying you either strip mathematical truths of any veridical status because they’re mental constructs or stop applying a double standard to moral truths. The notion that the universe is an illusion - besides being little more than fanciful conjecture - is irrelevant. Really. Irrelevant.
You mean justified for them, because I’ve yet to see a justification of slavery that can stand up to any rational examination.
As a moral relativist, I’ve yet to see a rational justification of libertarian rights. Even if I like those rights. Maybe I’m just not intelligent enough, but I’m not gonna accept anything based on authority .
