The concept of a “square one” in societal organization is a curious thing, and challenging analytic, given the stubborn presence of the past. Even if not meant literally, the Square One Project, like much of the polity, envisions a new starting point, where social policy and practice might turn in a more equitable and inclusive direction. Yet we must grapple with what this restarting point is, in a sociological rather than political sense, and how the present can reasonably be conceived–and actively reconfigured–as an opportunity to start over. I argue that the Square One Project imagines yet another societal reconstruction, in which attending to old and more recent histories of racial violence remains critical to achieving a sustainable vision and practice of equal and legitimate justice. To that end, I encourage a wide-ranging array of efforts under the banner of monumental antiracism to prepare the ground for square one justice.
