 The original project, advanced by Rawls and traditional Rawlsians, continues (Weithman 2011). But the coherence and diversity projects arose from a shared worry about it. Rawls uses both consensus and convergence reasoning in legitimizing state coercion. We first justify a conception of justice based on shared values, and we then see if it can become the object of an overlapping consensus. Coherence theorists say the first stage is critical, while the second stage is confusing. But diversity theorists say the second stage is necessary as a heuristic for finding points of convergence. Original project theorists refuse to choose between these two justificatory stages.
