 Within contemporary analytical philosophy, there are two different ways in which moral and political philosophers think about war (Lazar and Valentini forthcoming). On the first, institutionalist, approach, philosophers’ primary goal is to establish what the institutions regulating war should be. In particular, we should prescribe morally justified laws of war. We then tell individuals and groups that they ought to follow those laws. On the second approach, we should focus first on the moral reasons that apply directly to individual and group actions, without the mediating factor of institutions. We tell individuals and groups to act as their moral reasons dictate. Since this approach focuses not on the institutions that govern our interactions, but on those interactions themselves, we will call it the “interactional”  approach.[6]
