So, I think I could basically incorporate your view into the kind of framework that I prefer.

But I do think it is better - in a certain distinctive respect - for the social practice of appreciating artworks (like Hokusai prints) to be extended over more people and over longer periods of time, and for this social practice to involve the appreciation of a greater diversity of artworks.

This sounds very interesting! I think I reject the very idea of the "amount" of a value: this idea makes the value into a kind of stuff (like e.g. gasoline), where its "amount" is an extensive quantity (like the total mass or volume of this stuff in the universe as a whole).

This view is defended in my 2023 book, "Rationality and Belief", especially Sections 2.3, 2.5, 11.2 and 11.3. It still seems to me more plausible than the common view that such higher-order evidence can defeat propositional justification...
ralphwedgwood.bsky.social
In my view, higher-order evidence - like evidence that one is likely to be thinking irrationally about p - does not defeat one's propositional justification for believing p. But it may well make it impossible for one to believe p in a doxastically justified manner.

Even if I might, in the end, demur and prefer a different formulation, isn't there something incredibly compelling in what the Stoics say about this...?
ralphwedgwood.bsky.social
This kind of perception, I believe, is what motivated the ancient Greek and Roman Stoics to say that all of us who have a human mind are "children of God" (e.g. Epictetus, Discourses, 1.3).

The human mind is the most astounding phenomenon that we're aware of, in the whole of the natural world. But everyone reading this actually *has* a human mind! What an amazing privilege is that?!

Do I really want to wade into this debate? Do I have the competence to say anything about this that could be valuable for an audience of more than a few of my fellow philosophers? Perhaps I should try, anyway. It seems daunting, but I believe that I have insights into these questions.

I am coming to think that I need to write something (perhaps even a book?), arguing against all of the revealed religions -Judaism, Christianity, and Islam... - on both philosophical and historical grounds. and advocating a different approach towards understanding the basic problems of human life.

Later, 5 years ago, I acquired an interest in later Stoicism (of the 1st two centuries CE). So, I have been thinking intensely about that historical period. I'm convinced that the historical evidence about that period makes it probable that some of the most central claims of Christianity are false.

Almost 20 years ago, in summer 2025, I decided that, in the last 2 pages of my book "The Nature of Normativity" (as a surprise reward for any readers who made it that far into the book…), I'd argue that my kind of realism about normativity undercuts many motivations for theism and religious belief.

The short answer is: (1) We need to recognize "local" as well as "global" value-bearers (even though all value-bearers are states of affairs); (2) We need to embrace a thoroughgoing pluralism about values; (3) We need to reject "part-whole aggregation", recognizing only "multiple-value aggregation".

My talk at this workshop is going to explore the following question: If our ethical theory is to be (a) in a strong sense grounded in values, but (b) not even in a weak sense consequentialist, how should we think of these values?

Of course, within Jeffrey's framework, there is no "redescription" of "the outcome". For Jeffrey, outcomes are propositions, which are individuated by the worlds at which they are true. It's just obviously a different outcome!
ralphwedgwood.bsky.social
Great - thank you so much, Richard! I'm familiar with Buchak's book; but, so far as I can see, she doesn't discuss Jeffrey's decision theory in this connection at all. (There's no index entry for Jeffrey, and he is not mentioned in the Chapter on "Redescription").

From my perspective, Kant's monistic thesis, that all "absolute" goodness is explicable in terms of the purely "formal" goodness of the "good will", has absolutely no advantages over the blinkered utilitarian view that Price criticizes here. Price was so much more perceptive than Kant or Bentham...

"I deny not but that, in the human mind, as well as in the natural world, the most wonderful simplicity takes place; but we ought to learn to wait, till we can, by careful observation and enquiry, find out wherein it consists; and not suffer ourselves rashly to determine anything concerning it..."

"What mistakes and extravagances in natural philosophy have been produced, by the desire of discovering one principle which shall account for all effects?

His criticism of Hutcheson's utilitarian reduction of all virtue to benevolence is poignant:
"How unreasonable is that love of uniformity and simplicity which inclines men thus to seek them where it is so difficult to find them? It is this that, on other subjects, has often led men astray....

The overwhelming majority of ethicists in the history of Western philosophy have advocated excessively monistic unified theories. This is what makes Richard Price's pluralism about the "branches of virtue" all the more remarkable (see Chap. VII of his "Review of the Principal Questions in Morals").

In this way, Jeffrey–Bolker decision theory guarantees that the outcomes of different lotteries never count as strictly “the same outcome”. I remain somewhat puzzled about why the fact that this decision theory is immune to the Allais paradox is not more prominent in the decision theory literature.
ralphwedgwood.bsky.social
However, the Allais preferences are consistent with this principle. The first Allais preference concerns propositions A1 and B1 that are true in worlds where one has entered Lottery 1; the second preference concerns propositions A2 and B2 that are true in worlds where one has entered Lottery 2.

Admittedly, something similar to the STP holds in this theory: If A and B are equally probable, C and D are equally probable, and A, B, C, and D are all pairwise incompatible with each other, then, if you prefer ‘A or C’ over ‘B or C’, you must also prefer ‘A or D’ over ‘B or D’.
ralphwedgwood.bsky.social
Savage’s “Sure Thing Principle” (STP) is not an axiom of Jeffrey–Bolker’s version of decision theory. So, Jeffrey–Bolker’s theory is not threatened by the Allais paradox. Why is this point not discussed in the literature on the paradox?
ralphwedgwood.bsky.social
If we tried to state the STP in Jeffrey's theory, it would be this: If you prefer the prospect "A or C" over the prospect "B or C", you must also prefer "A or D" over "B or D". But this is obviously not in general true in Jeffrey's theory.

As an octogenarian, Philippa Foot tried to revive something like the Aristotelian link between ethics and natural teleology in "Natural Goodness" (2001). But I have to say, this seems a wild anachronism to me - like an attempt to revive Empedocles' theory of the 4 elements in the modern age.
ralphwedgwood.bsky.social
I guess we find a *kind* of eudaimonism revived in the work of 19th-century Hegelians like T. H. Green - but by then it has lost its grounding in any kind of natural teleology.
ralphwedgwood.bsky.social
A particularly interesting question, in my opinion, is why this sort of view came to seem implausible in the early modern period - even among those (like Butler, Reid, and Kant) who were not yet ready to reject natural teleology outright ....
