In Aristotle's Ethics as First Philosophy, Claudia Baracchi demonstrates the indissoluble links between practical and theoretical wisdom in Aristotle's thinking. Referring to a broad range of texts from the Aristotelian corpus, Baracchi shows how the theoretical is always informed by a set of practices, and, specifically, how one's encounter with phenomena, the world, or nature in the broadest sense, is always a matter of ethos.
