This article seeks to provide an answer as to why Metaphysics, Lam ends not with the justly famous account of the divine nous with which this book of the treatise is always associated, but with an aporetic account of the living and dying of everything mortal. This surprising moment, I argue, is a manifestation of Aristotle's conviction—quite alien to the mainstream understanding of philosophy as a discipline today—that even the purest moments of theoretical speculation are the work of a human (...) soul always in touch with its materiality and its subsistence in the world. A soul that only is at all when it is at work in living well, which is to say when the soul enacts itself in praxis. This means: the best understanding of the aporetic conclusion to Metaphysics, Lam is the one that asks us to recall that Aristotle's project of first philosophy—however much its most proper subject matter is the unchanging and immaterial—proceeds as part of a human life lived a certain way, and not as part of an academic discipline.
