Whose Justice? Which Rationality?
Whose Justice? Which Rationality? is a 1988 book of moral philosophy by the Scottish philosopher Alasdair MacIntyre. In the book, MacIntyre argues that there are a number of different and incompatible accounts of practical reasoning or rationality: those of Aristotle, Augustine, David Hume (and more broadly the "Scottish school"), and Thomas Aquinas. The differing accounts of justice that are presented by Aristotle and Hume, MacIntyre argues, are caused by the underlying differences in their conceptual schemes.
