No branch of this disjunction applies. Justifications for assumptions bottom out in EV of the reasoning, and so are justified when the EV calculation is accurate. A reasoner can accept less than perfect accuracy without losing their justification—the value of reasoning bottoms out in the territory, not the map, and so “survived long enough to have the thought” and similar are implicitly contributing the initial source of justification.
I can easily interpret this as falling into branches of the disjunction, and I am not sure how to interpret it as falling into none of the branches. It seems most naturally like a “justification doesn’t always rest on further beliefs” type view (“the value of reasoning bottoms out in territory, not map”).
Some beliefs do not normatively require justification;
Beliefs have to be justified on the basis of EV, such that they fit in a particular way into that calculation, and justification comes from EV of trusting the assumptions. Justification could be taken to mean having a higher EV for believing something, and one could be justified in believing things that are false. Any uses of justification to mean something not about EV should end up dissolving; I don’t think justification remains meaningful if separated.
Some justifications do not rest on beliefs
Justification rests on beliefs as inputs to EV calculations.
Some justification chains allowed to be circular
No conclusion requires its justification to be circular.
Some justification chains are allowed to be infinite and non-repeating
No infinite chains are required, they bottom out in observations as beliefs to be input into EV calculations.
