Even if this argument is successful, there are debates over decision theory (evidential, causal, functional). Does an ideally rational agent intervene at the level of states, actions, or decision procedures?
If it’s decision procedures, or something similar, functional decision theory can you get views that look quite close to Kantianism.
Just as a side note, Harsanyi’s result is not directly applicable to a formal setup involving subjective uncertainty, such as Savage’s or the Jeffrey-Bolker framework underlying evidential and causal decision theory. Though there are results for the Savage setup too, e.g., https://www.jstor.org/stable/10.1086/421173, and Caspar Oesterheld and I are working on a similar result for the Jeffrey Bolker framework. In this setup, to get useful results, the indifference Axiom can only be applied to a restricted class of propositions where everyone agrees on beliefs.
Thanks for this.
