Abstract
Where institutions are well-ordered and governed according to principles identified as necessary for justice, the attitudes and behaviors of citizens are also likely to be affected: they will develop a specific ethos that is appropriate for sustaining that just order. However, the absence of a substantially just basic structure will also take effect on what is considered an appropriate sense of justice suited to dealing with nonideal situations characterized by potentially profound injustice. Where ideal theory can describe an ethos necessary for supporting already just institutions and practices, we require a separate account of an ethos appropriate to nonideal conditions.
