The above are positive claims the ethical Supervenience is very tenable, i.e. the thesis, moral facts do supervene on natural facts. The articles also provide counter arguments against the above thesis. However, I do not think the counter arguments can dent the thesis.It is common for philosophers to endorse ethical Supervenience without much argument (an important exception is Smith 2004; for critical discussion of a variety of the arguments that have been offered, see Roberts 2018, 10–18).
Part of the reason for this is that ethical Supervenience is taken to be both obvious and uncontroversial.
(Rosen 2020 calls it “The least controversial thesis in metaethics”.)
Further, ethical Supervenience is often claimed or assumed to be an obvious conceptual truth, doubts about which are supposed to reveal conceptual incompetence.
The most common view in the literature is that the Supervenience of the ethical is a conceptual truth.
As the preceding sections have shown, philosophers have tried to extract a number of striking conclusions using ethical Supervenience as a premise.
Part of the motivation for these attempts is that ethical Supervenience is widely assumed to be a powerful dialectical weapon, such that if your view is incompatible with ethical Supervenience, it is in trouble. [5.0]
Here is AI with a summary of 2.0 Argument for Ethical Supervenience with a list of of the principles of the 'for' argument with examples:
The above merely summarize the principles with an example.AI wrote:From the idea that moral properties depend on natural properties. Here are some of them in simpler terms, with examples:
1. Argument from Explanation:
2. Argument from Metaphysical Dependence:
3. Argument from Analogy:
4. Argument from Queerness:
1. Argument from Explanation:
This argument suggests that if we can fully explain something (like moral properties), we need to explain it in terms of more basic things (like natural properties).
Example: Imagine trying to explain why stealing is wrong. You might explain the negative consequences of stealing (natural property) on trust and cooperation within a society (another natural property). These natural properties help explain why stealing is considered morally wrong.
2. Argument from Metaphysical Dependence:
This argument claims that if something wouldn't exist without something else, then the first thing depends on the second.
Example: Moral judgments often rely on facts about the natural world. For instance, judging harming someone as wrong depends on understanding pain as a natural property. Without the natural property of pain, the moral judgment wouldn't be possible.
3. Argument from Analogy:
This argument compares moral properties to other properties that are widely accepted to depend on natural properties.
Example: Just like the color red depends on the physical properties of light and our visual system, maybe moral properties like "good" depend on the natural properties of promoting well-being or flourishing.
4. Argument from Queerness:
This argument suggests that if moral properties were completely independent of the natural world, they would be strange and inexplicable.
Example: Imagine a world with completely different laws of physics. Our current moral framework might not make sense in such a world. This suggests a connection between morality and the underlying natural world.
It's important to note that:
These are just some of the arguments for ethical supervenience. The article discusses them in more detail and also explores counterarguments.
Not everyone agrees with these arguments. Some philosophers believe moral facts are independent of the natural world.
Hopefully, these simplified explanations and examples give you a better understanding of the arguments for why some philosophers believe moral properties supervene on natural properties.
To grasp the above principles we will have to go into the details [elsewhere].
My point:
The Supervenience in Ethics is merely one from the whole set of other arguments that support the thesis: there are moral facts [FSERC] and thus morality is objective.
Thus people like PH & gang should not merely brush off the claim there are no moral facts and morality cannot be objective based on the old paradigm of traditional arguments [currently losing bite] against moral facts apparently from a God and various philosophical realists.
