Aristotle's selection of eudaimonia to denote what he elsewhere calls ``Human'' or ``Practicable'' good, and the fact that, after all, we have no better rendering for eudaimonia than ``Happiness'' or ``Felicity'', has caused no little misunderstanding of his system. Thus when Stewart (Philosophy of the Active and Moral Powers, Book ii. chap. ii.) says that ``by many of the best of the ancient moralists … the whole of ethics was reduced to this question … What is most conducive on the whole to our happiness ?'' the remark, if not exactly false, is certain to mislead his readers; since by Stewart, as by most English writers, ``Happiness'' is definitely conceived as consisting of ``Pleasures'' or ``Enjoyments''.
