One of the core themes of Gary Jacobsohn’s work has been his observation that constitutional aspirations tend to develop within a disharmonic constitutional order. Jacobsohn draws our attention to Abraham Lincoln and Frederick Douglass as models for thinking about the unfolding of U.S. constitutional aspirations within a larger framework of constitutional disharmony. This essay revisits Jacobsohn’s theory of constitutional aspiration, including its underlying philosophical premises, and concludes by putting it in dialogue with recent revisionist accounts of the U.S. constitutional order that downplay, deny, or mute the aspirations that Jacobsohn’s body of scholarship highlights and celebrates.
