This helps explain why Aristotle thinks it appropriate to deploy his apparatus of core-dependent homonymy in the case of being. If we ask whether qualities or quantities exist, Aristotle will answer in the affirmative, but then point out also that as dependent entities they do not exist in the independent manner of substances.
