 Shelby responds that, while Rawls’s ideal theory of justice excludes a theory of rectification because it is not comprehensive, rectificatory justice is not only complementary but in fact presupposes an ideal theory that can clarify when injustices have occurred and need to be rectified. More importantly, Shelby suggests that complying with rectificatory justice through racial reparations could well leave Black people living in a society that nevertheless remains racially unjust in other ways. For this reason, Shelby concludes that ideal theory remains indispensable (2013).
