%0 Journal Article %T A substancia e o ser dos itens n o-substanciais em Z1 %A Raphael Zillig %J DoisPontos %D 2010 %I Universidade Federal do Paran¨¢, Universidade Federal de S?o Carlos %X Aristotle¡¯s discussion of substance at Metaphysics Z1 begins with an issue about the ontological status of some non-substantial items. This issue is usually understood as designed to establish substance as first being. In this paper, I argue for an alternative interpretation of Aristotle¡¯s move. The issue concerning the ontological status of some non-substantial items does not aim at establishing substance as first being, but to direct the investigation to the reason why substance is taken as first being. %K Aristotle %K Being %K First being %K Priority %K Substance %U http://ojs.c3sl.ufpr.br/ojs2/index.php/doispontos/article/view/14819/11755
