 Reasoning like this has led some philosophers to believe that pluralism is the key to explaining the complexity of real moral situations and the genuine tradeoffs that they involve. If some things really are incomparable or incommensurable, they reason, then pluralism about value could explain why. Very similar reasoning has led other philosophers, however, to the view that monism has to be right: practical wisdom requires being able to make choices, even in complicated situations, they argue. But that would be impossible, if the options available in some choice were incomparable in this way. So if pluralism leads to this kind of incomparability, then pluralism must be false.
