Prevailing interpretations of Aristotle’s use of syllogistic language outside the Organon hold that he offers a single, comprehensive theory of the practical syllogism spanning his ethical and biological works. These comprehensive theories of the practical syllogism are plausible neither philosophically nor as interpretations of Aristotle. I argue for a multivocal account of the practical syllogism that distinguishes (1) Aristotle’s use of syllogistic language to explain aspects of his account of animal motion in MA from (2) his use of syllogistic language (...) to explain aspects of his account of the distinctive practical cognition of the phronimos in EN. I offer a novel account of the role of syllogistic language in ethics, arguing that it elucidates a nuanced account of universals and particulars in ethics according to which acting virtuously requires an understanding of underlying universal values and a capacity to relate them to concrete, particular features of our circumstances.
