Aristotle on Ontological Priority in the 'Categories'

Attila Hangai, Institute of Philosophy at Research Centre for the Humanities, Budapest, reviews Aristotle on Ontological Priority in the Categories, by Ana Edelhoff, at Bryn Mawr Classical Review</a>.

"In her interpretation Aristotle uses two independent sufficient conditions for ontological priority that are disjunctively necessary: (A) necessary asymmetrical existential dependence (necessarily, if X exists, then Y exists, but not vice versa) and (B) necessary symmetrical existential dependence with the prior item being the cause of the posterior item."
