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.

This chapter focuses on constitutional disharmony as central to forging constitutional identity by looking at the place of Black citizenship prior to the Civil War. While there are powerful arguments that the Constitution could be seen as antislavery, even while it allowed for slavery to persist where it already existed, those who were antislavery did not give much thought to the place of Blacks within the constitutional order—particularly not to the question of Black citizenship. It was, rather, events such as the second Missouri Crisis of 1821 that forced the issue of Black citizenship onto the polity. Events forced constitutional actors to wrestle with questions that were not clear, or easily answered, by way of constitutional text. This chapter offers an important contrast to more prevalent approaches – to either originalism or moral readings – that too often try to dissolve constitutional disharmony.
