Proceduralism: A generic pattern of leading philosophies of value which assume that universal values can only be implicit in or decided by procedures of argument (i.e., “contractarian” models of justice and norms of “the ideal speech situation”), and whose rational “procedures” distinguish the different schools (i.e., self-maximizing choice versus undistorted consent).
