A subjective probability is not arbitrary. It is the most accurate estimate possible given the evidence to the subject. See http://lesswrong.com/lw/s6/probability_is_subjectively_objective .

I think you're misunderstanding me, but I can't think of a way to better phrase what I said, sorry.

Maybe if I put it thus: I can't think of a situation where some evidence E will make my posterior probability P(A|E) greater than 0.8 regardless of my prior P(A).

Yeah, re-reading the quote, I see what you mean. He seems to have confused a frequency with a probability distribution over possible values of the frequency. Maybe that's why he made the other error that the post discusses.
