On many important issues of science, philosophy, politics, and religion, equally knowledgeable and intelligent people often disagree with
one another. In this presentation I argue that on such matters, it is not epistemically justifiable to hold firmly to the correctness of one’s opinion, defined as one’s own subjective evaluation of the evidence. Rather, I argue that one’s opinion should receive no greater weight in constituting beliefs than does the opinion of any other equally informed person. I conclude by considering some common objections to my argument.
