IDEALIZATION, JUSTICE, AND THE FORM OF PRACTICAL REASON

Current debates about ideal theory and idealization in modern moral and political philosophy do not typically scrutinize the form of reflection itself. This is an unfortunate oversight: assumptions about the form of reflection shape the positions defended in those debates. I argue that the appropriate form of reflection on the nature and justification of standards of justice and morality is the form of practical reason. I further argue that the form of practical reason cannot support many of the idealizations typically deployed in modern moral and political philosophy.
