Abstract
Aristotle’s science writing serves as an instance of a classical science writer at work. Applying his theory of writing found in his Rhetoric, Poetics, Posterior Analytics, and Categories treatises to his History of Animals illustrates his work as a writer of life science. As rhetorical tools, his theory of tropes and figures and his theory of the model as developed in his theory of definitions and the enthymeme work as epistemic strategies. The essay concludes that further study should examine other rhetorical dimensions of his science writing.
