Cristiano Leone is a PhD student in Philosophy at Sapienza University of Rome (supervised by Professor Alessio Vaccari and Professor Piergiorgio Donatelli). His doctoral project, Sidgwick: Ethics, Economics, Politics, aims to provide a comprehensive account of Henry Sidgwick’s philosophy, challenging the traditional tendency to reduce Sidgwick’s thought to the moral philosophy of The Methods of Ethics. The project therefore aims to recover Sidgwick’s “global moral doctrine,” in Rawlsian terms, as in the case of earlier classical utilitarians such as Jeremy Bentham and John Stuart Mill. Cristiano Leone's research focuses on normative ethics, in particular utilitarianism and rational egoism, as well as applied ethics, with a special emphasis on economic ethics. More broadly, his work is concerned with the interconnections between ethics, politics, and economics, especially within a liberal framework. In this context, he has also undertaken coursework in economics, which supports his interdisciplinary engagement with the philosophical dimensions of economic theory.
