This chapter develops a “big history” account of the place of justice in the great tale of humanity. The “human web” is spun across the earth as a result of our cooperative capacities. It is the point of justice to reflect on what it means for each individual to have a proper place in that web. We explore how it would be legitimate to enroll authors from vastly different periods in a unified story. The evolutionary account of justice in the “conversation of mankind” provides an answer. My account is “quasi”-historical. I recount the history of the notion in a way that develops it in an era of global interconnectedness. Over time, both scope and reach have expanded until we arrive at a contemporary notion that is global in scope and whose reach is rather extensive. The grounds-of-justice view is a way of accounting for the concept of justice today.
