NICOMACHEAN ETHICS

certain difference is found among ends; some are activities, others

are products apart from the activities that produce them. Where
there are ends apart from the actions, it is the nature of the
products to be better than the activities. Now, as there are many actions, arts, and sciences, their ends also are many; the end of
the medical art is health, that of shipbuilding a vessel, that of
strategy victory, that of economics wealth. But where such arts fall under a single capacity- as bridle-making and the other arts concerned with the equipment of horses fall under the art of riding, and this

and every military action under strategy, in the same way other arts fall under yet others- in all of these the ends of the master arts
are to be preferred to all the subordinate ends; for it is for the
sake of the former that the latter are pursued. It makes no difference whether the activities themselves are the ends of the actions, or something else apart from the activities, as in the case of the sciences just mentioned.�
