Imagine two different characterizations of some mathematical object as the infinite limit of some process, say two different infinite sums, or an infinite sum vs an infinite product, or the argmax of a function found by exhaustive search through an infinite search space vs a fixed point of a dynamical system computed iteratively.
On the one hand, it would be absurd for the proponents of say an infinite product representation of a positive number to think that they've "refuted" an infinite sum representation because one of its partial sums is negative.
But on the other hand, depending on the task at hand, noting that a sum converges slowly, or that an exhaustive search has no optimality guarantees if truncated at finite steps, are genuinely valid criticisms of those representations even if, in some sense, they are correctly calculated approximations of the true ideal object.
Which is to say, I think there's a middle ground where we try and understand objective features of the finite approximations and how they compare to each other and to the ideal object they approach.
I gather from your writing that most deontologists aren't past the stage of pointing out, "the 1000th partial sum of your series for Pi is (negative/rational/algebraic) but everyone knows that Pi is (positive/irrational/transcendental)! Refuted!" so I think it's fair to stress the distinction between ideal and non ideal.
But I still think there is a better argument that has some of the same form that I don't think is addressed by the distinction, something like the claim that "consequentialism converges very, very slowly and requires intractably many terms to compute before you get results that can be achieved with just the first few terms of other theories" (note I don't claim this is true, but I think it's a better version of the sort of thing deontologists are claiming).
Appealing to the necessity of a better decision theory strikes me as similar to someone using the arctan series for Pi appealing to the need for better calculators. Maybe, but maybe it's a problem that you've chosen a slowly converging sum, and for any given strength of calculator you could do better (at certain tasks) by just picking a different representation.
I wholeheartedly agree with your analysis and hope it reaches a wider audience. In my view, ethics is a field where many different questions are often mixed together. If you're interested, I’ve written a paper on this issue (specifically in the context of teaching ethics).
(Though regarding your offhand mention of satisficing - I think the concept of satisficing has often been crudely adopted by philosophers as the idea that there is some threshold such that everything above that threshold is “good enough” and everything below that threshold isn’t, while I think Herb Simon intended it as a decision procedure where one evaluates options one by one in the order they come to mind and then does the first one that passes the threshold. It could well be that this decision procedure with a particular threshold actually optimizes the tradeoff of time considering vs goodness of act done.)
Thanks! And yeah, my interest in satisficing has more to do with demandingness-moderating prerogatives than with the search costs and such that originally motivated the economic concept (which, as you say, is plausibly tied to all-things-considered optimizing!).
I find it strange that you are taking such an approach. Philosophers are explicitly telling you they are talking about the ideal and you seem to be just saying "you mean non-ideal". What else can they do other than communicate to you that they are talking about the ideal?
Your intuitions may be about the ideal or the non-ideal. Looks like you think they are always on the non-ideal? But this means they are just reflections of society. Which predicts that your intuitions should almost never contradict societal norms. Is this the case?
I think it's not a coincidence that the putative "counterexamples" to consequentialism that people tend to find most compelling are cases in which it would plausibly *have bad results* for people to attempt to follow the supposedly "consequentialist" verdict (which raises the question of why we should consider that the "consequentialist" verdict to begin with).
But to make further dialectical progress, I'd encourage critics of consequentialism to engage more explicitly with what I call the "telic" question. Do you think it would be *undesirable* for the better outcome to occur? If so, that suggests that you really do reject consequentialism! But do you think it is *intuitively obvious* that the better outcome is undesirable, such that your intuitive response here counts as some kind of dialectical *datum* that any adequate theory must accommodate? Surely not. So stop treating superficial verdicts about cases as decisive, and start doing some deeper theorizing.
"which it would plausibly *have bad results* for people to attempt to follow the supposedly "consequentialist" verdict"
I think one of their objections is more along the lines that consequentialists are unable to recognize these as bad things, because of their (Gradgrindian) commitments.
“Non-ideal” is not the same as society. It is rather the status of being a finite physical being. Non-ideal intuitions are going to be cultivated by biology and physics as much as by society.
I didn’t mention evolution in particular. What I did mention is being a finite physical being, which has many, many aspects, only one subset of which come from evolution.
Yes, I agree in that post that vegetarianism is *recommended*! But not everything that goes against moral advice is *wrong* in the strong sense specified in the quote. I think the latter depends a lot on existing social norms.
If we imagine a society with well-established vegetarian norms, I think it would be plainly wrong for a person in that society to eat meat. Similarly, if there's a well-established norm that people donate 10% of their income to effective charities, then it would be wrong to do less than that. In general, it's wrong to violate good norms that are well-established. (This is partly because, as natural conformists, it's generally quite easy for decent human beings to do what's generally expected and followed by everyone around them.)
The trickier question is what to say about things that *would* be good norms, but (sadly) aren't in fact socially established. Assuming that it's not a weird case where there would be bad effects from just a few people following the norm when others don't, we can of course say that it's *recommended* that one do this good thing. The "ought of most reason" will prescribe it. But it's a further question whether it's *obligatory* in the stronger sense that it would be outright indecent and blameworthy to fail to do it.
Here I see two principled options (oversimplifying slightly):
(1) The strict view that it's actually outright indecent for people to live ordinary lives when our ordinary norms aren't what they should be. On this view, everyone is obligated to donate at least 10% (maybe more!), be vegan, etc.
(2) The moderate view that while it would be *good* to follow better norms, one isn't especially blameworthy or indecent so long as one is broadly honest and cooperative and follows the good norms that have been established as social expectations in one's community.
On ideal vs non ideal:
Imagine two different characterizations of some mathematical object as the infinite limit of some process, say two different infinite sums, or an infinite sum vs an infinite product, or the argmax of a function found by exhaustive search through an infinite search space vs a fixed point of a dynamical system computed iteratively.

Section 2 may be particularly relevant to your work, especially my analysis of the notion of "rightness" in the context of ethics.
This all sounds exactly right to me!

I am now more confused.

So then if you contradict society it must come from evolution? Also a weird inference.

I'm more inclined to the second view. For more detail, see my paper on 'Willpower Satisficing': https://philpapers.org/rec/CHASBE-4
