Abstract
I try to show that Aristotle does not restrict 'praxis' to those activities which have their end in themselves. NE VI 5, 1140b6-7 need not to be taken as an argument in favour of the restricted interpretation: the wording of the passage is compatible with the interpretation that the end of a praxis is (another) praxis (e.g. eupraxia), the end of a poiesis on the other hand is never a poiesis. This interpretation fits better the use of 'praxis' throughout the NE. MM A 34, 1197a4-12 is discarded since the MM is not written by Aristotle. Next I discuss the relation between the verbs 'prattein' and 'poiein' on the one hand and the corresponding nouns 'poiesis' and 'praxis' on the other, in order to determine their exact meaning. To conclude, Aristotle's distinctions are compared to certain tenets of H. Arendt in her 'Vita Activa'.
