Institution et justification. De la nécessité de distinguer deux conceptions de la justice

This paper deals with the place of the concept of justification in the processes of institutions in modern societies. A synthesis is proposed between Commons? transaction theory and Boltanski and Thevenot justification theory. This synthesis involves tearing down and re-building both of these theories with the help of the American philosopher MacIntyre, who distinguishes two general conceptions of justice: the first in terms of excellence, and the second in terms of efficient coordination.
