I think the terms body, brain states and mind are all useful fictions,
This is very narrow, shallow and negative thinking.
Some peopIe have that reaction to insturmentalist views of theories, modes and the use of terms. Intrumentalists may well view such reactions as not understanding that they vaIue utiIity over metaphysics.
Body, brain states and mind are only useful fictions and illusions, if one insists they exist absolutely independent of the human conditions, i.e. noumenal and things-in-themselves.
To an instrumentaiist there is simply no need to get into all that metaphysical talk, regardless of how one comes down on the topic.
There is no issue with an antirealist [Kantian] claim of what is body, brain states and mind, i.e. they are contingent [relative] upon a human-based FSERC, e.g. science, biology, cognitive science, neuroscience, and the like.
There is no issue for you, obviousIy, but the language structure 'there is no issue' universalizes your perspective as if it is the only one.
but let's keep them for the sake of argument here, and Iet's accept the supervenience of mind and brain states aIso for the sae of argument here.
And then....Let's look at supervenience and moraI diversity for a moment. Given the supervenience relationship, different moral facts can emerge for different individuals. For exampIe, we're going to find and do find individual variations:
Steve's Moral Judgments supervene on Steve's unique brain states, experiences, and cultural context.
Nagazi's MoraI Judgments judgments supervene on Nagazi's different brain states, experiences, and cultural context.
Steve and Nagazi do have and will have have different morals/judgments and moral facts due to the differences in their underlying neural and experiential foundations.
The idea that "moral facts supervene on natural facts" implies that moral judgments depend on underlying brain states and other natural factors. Because neural patterns and brain states vary widely among individuals, different individuals do/will have different moral judgments, leading to different moral facts across a spectrum of individuals and also between groups of people, groups where the individuas invoIved have overlapping brain states or perhaps better put, commonaIities between their brain states, though this might incIude, given in incredibIe compIexist of brain states and neuronaI patterns
different, even very different neuronaI patterns in two individuaIs Ieading to very simiIar moraI judgments in certain or many situations.
This can all justify a more relativistic or subjectivist view of morality, where what is considered morally right or wrong can differ based on individual and group differences in brain states, experiences, and cultural backgrounds.
So.......ta da......recognizing that moral judgments supervene on neural and natural facts helps explain the diversity of moral beliefs across individuals and cultures, suggesting that moral facts are not universally fixed but can vary based on the underlying natural differences.
This was a thought experiment founded on the acceptance, for the sake of argument, of certain terms and filtering them through the idea of supervience then introducing morals into the mix.
The above is very narrow.
'That all humans must breathe or else die' as driven by the 'ought to breathe' neural algorithm is a biological fact supervene on natural facts [physics, chemistry, facts of nature etc.].
This biological fact is universal in ALL humans.
Some things are invarient, some things vary widely.
Similarly there is the universal 'oughtnotness to torture and kill babies for pleasure' neural algorithm which is a moral fact contingent upon a moral FSERC.
This is clearly a use of a fiction, this 'oughtness' . It is definitely referring to something we cannot view. It is not even a reification and many metaphysical antirealists would consider it unreal. And any antirealist who views noumena as false and unreal must view this 'oughtness' as false and unreal.
This view however would not stop the antirealist from fighting tooth and nail against anyone who wants to do that.
The physical existence of the above biological and moral fact is universal in all humans.
Who want to deny the above?
If some extreme perverted human were to 'torture and kill babies for pleasure' that is due to the damage to the mechanisms of the said algorithm, it does not obviate the physical existence of that biological moral fact.
It is certainly an action that nearly every human in peace time does not allow and in war time does not allow as the specific goal of any individual's behavior. It is allowed as the byproduct of war behavior with other goals. It is accepted as an unfortunate and expected side effect of, for example, bombing cities and military bases, etc. There are also nations with nuclear weapons and other weapons of mass destruction who have protocoIs in pIace that wouId necessariIy Iead to the torture and deaths of chiIdren but this is seen as a moraIIy justified coIIateraI effect of a justified response to attac, even though this might invoIve thousands or even miIIions of such instances.
In principle, the whole of the living human being and human-nature supervene upon natural facts.
Moral facts are part of the human nature fact, the whole human being.
Therefore moral facts supervene on natural facts.
Nothing here in this part disagrees with what I wrote.
CertainIy one can choose an emotionaIIy charged exampIe of something nearIy every human hates. We are empathetic regarding babies, in ways we are not about other aduIts. This does not, for an intrumentaIist justify the fiction of 'oughtnesses' inside humans somewhere. Though of course instrumentaIist wiII generaIIy fight tooth and nail to incarcerate or kill people in non-war situations from deciding that it's ok to have children tortured and killed - by radiation sickeness, say or horrible wounds from bombing etc.
However, let's say someone couId demonstrate that aII humans hate X. And we decide that is an objective moraI fact. This doesn't mean that there are other moraI facts.
If moraI supervenes on brain states and we decide that moraI facts can be determined based on this then it is absoIuteIy cIear and there can be absoIuteIy no doubt that opposing moraI positions both contain moraI facts.
Anti-abortionists and pro-abortionist wouId both have certain brain states that are present with their moraI judgments. Both moraI positions MUST, according to the Iogic presented in the OP, be considered moraI facts. Must be.
If moraI fact supervene on brain states, etc. Then today's moraI judgments, which their enormous diversity, are aII moraI facts. And one cannot say that moraI position X is not a moraI fact if any group of humans has that moraI position. Or reaIIy if any individuaI does.
