Hello again. I regret that so much time has passed. My problem seems to be that I haven’t yet properly understood everything that goes into the epistemology and decision-making of an infra-bayesian agent.
For example, I don’t understand how this framework “translates across ontologies”. I would normally think of ontologies as mutually exclusive possibilities, which can be subsumed into a larger framework by having a broad notion of possibility which includes all the ontologies as particular cases. Does the infra-bayesian agent think in some other way?
I would say the translation across ontologies is carried out by “computationalism” in this case, rather than infra-Bayesianism itself. That is, (roughly speaking) we consider which computations are instantiated in various ontologies, and base our loss function off of that. From this viewpoint infra-Bayesianism comes in as an ingredient of a specific implementation of computationalism (namely, infra-Bayesian physicalism). In this perspective the need for infra-Bayesianism is motivated by the fact that an agent needs to have Knightean uncertainty over part of the computational universe (e.g. the part relating to its own source code). Let me know if this helps clarify things.
