This book aims to elaborate a phenomenological description of moral experience as summarised in the view that moral experience functions as a starting-point to every theoretical description of morality and as a first principle on the basis of which we can draw criteria in order to evaluate moral actions and moral agents. Apart from relying upon phenomenological insights, Kontos clarifies his claim using a text-centered reading of Aristotle's Nicomachean Ethics. In the end, Kontos finds that moral experience is founded on a phronetic perception capable of recognizing schemata that synthesize a world susceptible of being invested with moral qualities; these same schemata, qua ontological categories of moral action, are what practical theory appeals to in its attempt to articulate or evaluate core principles of normativity.
