  Thus, there are disagreements over what to believe and what to do. Despite this distinction, we can achieve some simplicity and uniformity by construing disagreements over what to do as disagreements over what to believe. We do it this way: if we disagree over whether to do action \(X\), we are disagreeing over the truth of the claim ‘We should do \(X\)’ (or ‘I should do \(X\)’ or ‘\(X\) is the best thing for us to do’; no, these aren’t all equivalent). This translation of action-disagreements into claim-disagreements makes it easy for us to construe all disagreements as disagreements about what to believe, where the belief may or may not concern an action. Keep in mind, though, that this “translation” doesn’t mean that action-disagreements are just like belief-disagreements that don’t involve actions: the former still requires a choice on what one is actually going to do.
