JLS (not the band) comments "Again, one would need to trace one's argument back 
to Foot's actual words, not her obituarist." It would seem the obituarist 
believed it was her view. It was the reported view I was criticising 
(obviously). If she were alive it might be proper to clarify this and, in the 
light of Robert Paul's remark, retract any possible suggestion it was her 
actual view, if it was not.

It is not necessary to identify the 'naturalistic fallacy' with Moore's views 
any more than it is necessary to identify the right account of 'dialectical 
materialism' with Marx, or of utilitarianism with Bentham, or of 'empiricism' 
with Locke, or of 'falsificationism' with Popper, or of 'the private language 
argument' with Wittgenstein. 

In broad terms the 'naturalistic fallacy' is about whether an 'ought' can be 
derived from an 'is' or whether a standard of evaluation can be deduced from a 
set of facts. As such, it predates Moore in the form of 'Hume's Fork' and in 
Kant's 'Critique of Practical Reason' etc. It was a central contention of P's 
_TOS&IE_ that forms of the fallacy lie at the heart of many political theories, 
including those of Plato, Hegel and Marx. Any view that seeks not merely to 
partially explain but to fully reductively explain 'morality' in factual terms, 
is arguably perpetrating the fallacy.

The argument Popper uses in the addendum of the _TOS_, under the heading 'The 
Dualism of Facts and Standards' [afair], was presented in summary in my 
previous post and differs from Moore's argument, not least because it crucially 
does not rely on any definitional argument. As suggested by the entry Robert 
quotes, "The merits of [Moore's definitional] argument are questionable..." 
That is, the view that the dualism of facts and standards can be established, 
by showing its negation cannot be true by definition, is weak - as this would 
not show the dualism was true by definition either:- in truth the 'dualism' 
here is unavoidably a metaphysical/untestable claim. 

It is therefore possible to reject Popper's argument - for example, on the 
basis that, while it might seem that the open-ended ability to ask of any given 
'fact' "Is it good?" shows we can always open up a critical gap between facts 
and standards, it is delusion to think our answer to the question "Is it good?" 
is other than factually determined and so the apparent 'gap' is a delusion 
also. 

Taking this issue further, for Popper, would involve examining the notions of 
'determinism' [which is the focus of his "The Open Universe: An Argument For 
Indeterminism"] and 'reductive explanation'. An interesting logical point 
Popper makes about 'reductive explanation' is that a confusion underpins much 
support for 'reductive explanation':- a confusion between a scientific 
reduction which increases falsifiability/testability by, say, accounting for 
'facts' previously requiring more than one theory by way of only one theory of 
wider scope and thus testability, and a 'metaphysical reduction' which lessens 
falsifiability by denying the existence of a class of entities [such as 'mental 
events' that are not merely 'physical events'; or 'moral claims' that are not 
merely explicable in 'factual terms'] where any class of such entities are 
potential falsifiers of the view that denies their existence. 

Another important point he makes is that while there have been some partially 
successful reductions there have not been any completely successful ones: 
Russell failed in his attempt to completely reduce maths to logic, and while 
there have been some successful partial reductions in science it remains the 
case that chemistry is not completely reducible to physics nor biology to 
chemistry. This incompleteness of 'reductive explanation' is linked to the fact 
that distinct and 'higher-level' problems emerge as we progress from logic to 
maths and as we progress from considering the physics of the world to its 
chemistry, then biology, then psychology, then sociology etc.
