Eric, it's more amusing that both often cite a theorem that agreeing to disagree is impossible. And even more amusing that in "Nature of Logic" Eliezer practically explained agreeing to disagree: our mind is more cognition than logic. Eliezer and Robin generalize from facts to concepts differently which leads them to different predictions. When they try using logic to reconcile, logic kinda bottoms out at the concepts and there doesn't seem to be any way out except to test both theories. The argument goes on because both are polite and respectful, but it doesn't seem to shed any light.

(I apologize to the hosts for harping on the same topic repeatedly.)
