On the Five Analogies in Aristotle’s Metaphysics IX.6 陳斐婷 清華大學哲學研究所助理教授 Aristotle offers five analogies (1048a37-b4) in Metaphysics IX.6 to illustrate the new kind of actuality and potentiality that he aims to establish in Met. IX: actuality stands to potentiality, just as (a) building a house stands to being capable of building a house, (b) being awake stands to being asleep, (c) seeing stands to being capable of seeing, (d) being distinguished off from the matter stands to being not distinguished off from the matter, and (e) being finished off stands to being not finished off. Scholars such as Stephan Makin (2009) and Jonathan Beere (2010), who associate (a) (b) (c) with the change-capacity relation and (d) (e) with the substance-matter relation, are pessimistic about discovering one unifying account of the new kind of actuality and potentiality. In this paper I refute this pessimistic view and seek to interpret the five analogies in one unifying account instead. I argue that both those involved with the so-called change-capacity relation and those involved with the so-called substance-matter relation present a double-characterization that all the five analogies are composed of. While the first tier stands the relation of change (κίνησις) to the corresponding capacity, the second tier stands the relation of exercise (χρῆσις) to the possession of one’s own nature or a certain craft.
