Ferguson starts with the commonplace assumption within political philosophy that the family provides the ideal model for political association. Yet, as Ferguson points out, families are not necessarily harmonious units. Rather, families are often characterized by strife, unpleasantness, and poor communication. Ferguson asks: what if we started from these places of conflict and incommensurability to think about how political associations should function? He takes up several situations - from the love we have for our pets to the difficulties of taking care of a sick family member - to think about how familial attachments can offer insight into the creation of a pluralistic and democratic society.

Western political philosophers since Plato have used the family as a model for harmonious political and social relations. Yet, far from being an uncontentious domain for shared interests and common values, the family is often the scene of intense interpersonal conflict and disagreement. In All in the Family, the political theorist Kennan Ferguson reconsiders the family, in its varied forms, as an exemplar of democratic politics and suggests how real rather than idealized family dynamics can help us to better understand and navigate political conflict.

By closely observing the attachments that arise in families despite profound disagreements and incommensurabilities, Ferguson argues, we can imagine a political engagement that accommodates radical differences without sacrificing community. After examining how the concept of the family has been deployed and misused in political philosophy, Ferguson turns to the ways in which families actually operate: the macropolitical significance of family coping strategies such as silence and the impact that disability and caregiving have on conceptions of spatiality, sameness, and disparity. He also considers the emotional attachment between humans and their pets as an acknowledgment that compassion and community can exist even under conditions of profound difference.

"“Among the many strengths of this book, the greatest might be the way Ferguson uses the perspective of family life to pull together and explore an uncommon variety of ideas about politics and community… But it is to Ferguson’s immense credit as a thinker and writer that he allows his argument to range across such a breadth of ideas within social and political theory without ever leaving the reader confused or disoriented.”" - Theory & Event
