There are more ways to be complicated than there are to be simple. Starting with a complicated prior doesn't (EDIT: necessarily) get you closer to the complicated truth than starting with a simple prior does. Even if the truth is complicated, a complicated prior can be wronger than the simple one.
Yes, a complicated prior can be wronger than the simple one and usually is. I am sure I haven't disputed that.
Sorry, maybe I misread. The line I quoted above seemed to suggest that "if the laws of nature were complicated," then we would be better off having priors that favored complicated beliefs over simple ones — or at least considered them equal — rather than an Occam prior which favors simple beliefs.
I have suggested that we would be better off having priors which favour the exact way of how the laws are complicated. Of course, a general complicated prior wouldn't do the job.
