merjet Posted November 13, 2020 Report Share Posted November 13, 2020 What do you regard as nonsense -- naturalistic fallacy or naturalistic fallacy fallacy or both? The first makes sense to me, but not the second. Quote Link to comment Share on other sites More sharing options...
2046 Posted November 13, 2020 Report Share Posted November 13, 2020 So this guy named Hume (1739) said you can't deduce an ought statement from a statement with no ought in the premises because valid deductive arguments can only contain in their conclusions components that are fully supported in their premises. That is 100% correct. People confuse this with all sorts of things. They will say you can't derive an is from an ought, you can't get an is from an ought, and so forth. And then they will confuse the "naturalistic fallacy" which was put forth by Moore (1903) with Hume. They're not the same thing. There's more sophisticated contemporary notions, however, in which the gap is reconstituted to be ontological or semantic, say, rather than logical. Moore proceeds by looking at the way terms are commonly used in arguments as opposed to the actual definition of the terms. He claims that calling some thing X a good X is a fallacy because goodness does not refer to the properties of anything. He concludes that goodness is an undefinable and sui generis. He does this by way of the open question argument (OQA.) As best as I can charitably interpret, the second one (naturalistic fallacy fallacy) is trying to get at is that is-ought gap and naturalistic fallacy aren't fallacies, so invoking them is itself a fallacy. I guess. But I would personally wouldn't employ the "fallacy fallacy" strategy. I would rather point out it's just hand wavey from people who have generally never actually read Hume and Moore and don't really know what the arguments are.

dream_weaver Posted November 14, 2020 Report Share Posted November 14, 2020 I did a search for "anti-naturalistic fallacy" and found this to be helpful. The Utilitarian and Skeptics are the prevailing theme. The section on Ethical Objectivism managed to omit any reference to Ayn Rand.

This is not a "valid deductive argument," per @2046's post. You'd need an additional premise that an entity ought to perform the function it was created to perform to make the argument deductively valid. 2046 1 Quote Link to comment Share on other sites More sharing options...

I was trying to reach an objective definition of this batch of fallacies, and I'm finding it very difficult because of all the rationalism involved in the sources. I was hoping someone else already had it figured out. The only way to make these fallacies 'work', in my conclusion, is to take nature as existence apart from man as the definition, and then observe the fact-value distinction with that in mind: Moral statements cannot be derived from facts in nature. To do so is to commit the naturalistic fallacy. Nature cannot be morally evaluated (based on Pinker's examples) and moral sentiment does not determine facts of nature (based on Wikipedia's examples). To do either is to commit the moralistic fallacy. The anti-naturalistic fallacy, and even Frankena's 'definist fallacy' in this context evaporate, so I'm dismissing them. As for is-ought: I'm not ready to deal with that yet. I file 'application of a moral principle' under 'deduction', maybe that's a problem.

ppw Posted November 19, 2020 Author Report Share Posted November 19, 2020 That's not an understanding of the naturalistic fallacy as put forth by Moore, who argues that the concept of the good is irreducible. What you quoted was my re-definition. (I had hoped to make that clear.) Otherwise I have to throw them all out, because none of them are valid. They just represent a battle between two kinds of intrinsicism; "ethical intuitionism" and "ethical naturalism". Quote Link to comment Share on other sites More sharing options...
dream_weaver Posted November 19, 2020 Report Share Posted November 19, 2020 Here's a haphazard way of approaching it. Ethics Explainer: Naturalistic Fallacy Main take-away: The naturalistic fallacy is an informal logical fallacy which argues that if something is ‘natural’ it must be good. It is closely related to the is/ought fallacy – when someone tries to infer what ‘ought’ to be done from what ‘is’. Naturalistic fallacy: (Wikipedia entry. Doesn't hone in on O.P.) Moral Non-Naturalism (Standford Encyclopedia of Philosophy) The naturalistic fallacy is very poorly named indeed (a point also made by Bernard Williams; see Williams 1985: 121–122). For not only is it not especially a problem for naturalists, it is also not really a fallacy even if Moore is right that it embodies a mistake of some kind. For it is highly uncharitable to charge anyone who advances the sorts of arguments to which Moore alludes as having committed a logical fallacy. Rather, charity demands that we interpret such arguments as enthymematic, and usually this is easy enough. New term (to me): enthymematic enthymematic, (Wikipedia entry) A syllogism consists of the following: Major Premise Minor Premise Conclusion entheymematic: a syllogism missing one of these three components. Naturalistic fallacy|ethics|Britannica Fallacy of treating the term “good” (or any equivalent term) as if it were the name of a natural property. . . . The gist, to me so far, is being "natural" is the good. There are problems introduced. Not cited, but contained in the links—from Ethics Explainer: The naturalistic fallacy looks like this: Breastfeeding is the natural way to feed children. Therefore, mothers ought to breastfeed their children and ought not to use baby formula (because it is unnatural). This is a fallacy. We act against nature all the time – with vaccinations, electricity, medicine – many of which are ethical. Lots of things that are natural are good, but not all unnatural things are unethical. This is what the naturalistic fallacy argues. One of the problems with this latter (since the . . . ) is the treatment of man-made grasps and their implementations as "acts against nature". merjet 1 Quote Link to comment Share on other sites More sharing options...
