 It is unclear from Sherman’s interpretation of Aristotle whether there are principled reasons to limit the extent to which we share our identities with our friends; perhaps an appeal to something like Friedman’s federation model (1998) can help resolve these difficulties. Friedman’s idea is that we should understand romantic love (but the idea could also be applied to friendship) not in terms of the union of the two individuals, in which their identities get subsumed by that union, but rather in terms of the federation of the individuals—the creation of a third entity that presupposes some degree of independence of the individuals that make it up. Even so, much would need to be done to spell out this view satisfactorily. (For more on Friedman’s account, see the entry on  love,  the section on  love as union.)
