Aristotle on Teleology and Human Life Expectancy

Abstract This paper argues that, contrary to prevalent interpretations, Aristotle thinks of the natural lifespan of human beings as a natural phenomenon admitting of a teleological account. Though humans would have benefitted from living longer lives, in principle, there are teleological reasons for them to die when they do, pertaining to the prospects of individual and political flourishing, as well as to the maintenance and improvement of the species. This reading is supported by the discussion of old age in the Rhetoric. It also has significant consequences for our understanding of Aristotle's natural teleology and his views on human experience.
