But much of the material on LW is concerned with rational oughts: a rational agent ought to maximise its utility function (its arbitary set of goals) as efficiently as possible. Rational agents should win, in short. That seems to be an analytical truth arrived at by unpacking “rational”. Generally speaking, where you have rules, your have coulds and shoulds and couldn;t and shouldn’ts. I have been trying to press that unpacking morality leads to the similar analytical truth: ” a moral agent ought to adopt universalisable goals.”
I expressed myself badly. I agree entirely with this.
“Oughts” in general appear wherever you have rules, which are often abstractly defined so that they apply to physal systems as well as anything else.
Again, I agree with this. The position I want to defend is just that if you confine yourself strictly to natural laws, as you should in doing natural science, rules and oughts will not get a grip.
I think LWers would say there are facts about her utility function from which conclusions can be drawn about how she should maximise it (and how she would if the were rational).
And I want to persuade LWers
1) that facts about her utility functions aren’t naturalistic facts, as facts about her cholesterol level or about neural activity in different parts of her cortex, are,
and
2) that this is ok—these are still respectable facts, notwithstanding.
I don’t see why. If a person or other system has goals and is acting to achieve those goals in an effective way, then their goals can be inferred from their actions.
But having a goal is not a naturalistic property. Some people might say, eg, that an evolved, living system’s goal is to survive. If this is your thought, my challenge would be to show me what basic physical facts entail that conclusion.

And they are likely to riposte that facts about her UF are naturalistic just because they
can be inferred from her behaviour. You seem to be in need of a narrow,
sipulative definition of naturalistic.

You introduced the word “basic” there. It might be the case that goals disappear on
a very fine-grained atomistic view of things (along with rules and structures and various other things). But that would mean that goals aren’t basic physical facts. Naturalism tends to be defined more epistemically than physicalism, so the inferrabilty of UFs (or goals or intentions) from coarse-grained physical behaviour
is a good basis for supposing them to be natural by that usage.
And they are likely to riposte that facts about her UF are naturalistic just because they can be inferred from her behaviour.
But this is false, surely. I take it that a fact about X’s UF might be some such as ‘X prefers apples to pears’. First, notice that X may also prefer his/her philosophy TA to his/her chemistry TA. X has different designs on the TA than on the apple. So, properly stated, preferences are orderings of desires, the objects of which are states of affairs rather than simple things (X desires that X eat an apple more than that X eat a pear). Second, to impute desires such as these requires also imputing beliefs (you observe the apple gathering behaviour -naturalistically unproblematic- but you also need to impute to X the belief that the things gathered are apples. X might be picking the apples thinking they are pears). There’s any number of ways to attribute beliefs and desires in a manner consistent with the behaviour. No collection of merely naturalistic facts will constrain these. There have been lots of theories advanced which try, but the concensus, I think, is that there is no easy naturalistic solution.

Oh, that’s the philosopher’s definition of naturalistic. OTOH, you could just adopt the scientists version and scan their brain.
Well, alright, please tell me: what is a Utility Function, that it can be inferred from a brain scan? How’s this supposed to work, in broad terms?
