I still have not read the book. But here is the most informative review I have seen. Brad Littlejohn writes,
Using the model of a family and a business as contrasting types, Hazony highlights the extent to which modern political philosophy has come to treat the relations of political order as fundamentally like those of a business: “governed primarily on the basis of the individual’s assessments as to what will enhance his physical welfare and protect and increase his property, and by his ongoing consent to the terms of an agreement with others for the joint attainment of these purposes” (83).
In fact, however, a closer look at both the historical foundations of most political orders, as well as the conditions that enable states to continue to flourish, reveals relations more like those of a family: bonds of mutual loyalty anchored, indeed, by an initial act of mutual consent, but sustained through thick and thin by a sense of mutual belonging, mutual indebtedness, and mutual duty to “pass on to another generation an inheritance that has been bequeathed to us by our parents and their ancestors” (85). Whereas the former model encourages us to ask at every moment whether the arrangement is serving our interests, and to cut loose if it ceases to, the latter model encourages us “to stand true in the face of adversity, to refuse the urge to start everything anew” (88).
Read the whole thing. I only picked this excerpt because it reminded me of the distinction between sub-Dunbar and super-Dunbar. Hazony is saying that a nation-state, which is super-Dunbar in terms of population size, holds together because people feel the sort of attachment to one another that they feel in a sub-Dunbar setting. There is an obvious tension here, and Littlejohn dwells on Hazony’s attempts to deal with it.
Much later, Littlejohn writes,
Should America become a majority-minority nation, or—more decisively—should it lose its confidence in the culture and traditions that have actually sustained our political order over two and a half centuries, our abstract ideals of freedom, equality, and democracy would quickly cease to have motivating force to maintain a viable political identity or set of mutual loyalties. Which, come to think of it, sounds an awful lot like a diagnosis of our present condition.
