<p>This article introduces and explores the ethical theory of Robust Exemplarist Natural Law, which is a combination of John Finnis’s Natural Law Theory and Linda Zagzebski’s Exemplarist Moral Theory within the framework of Robust Realism proposed by David Enoch and Russ Shafer-Landau. It aims to integrate moral realism’s objective truths with the notion of basic goods and the principles of practical reasonableness, with the influence of moral exemplars on belief and behaviour formation. In achieving this end, a robust ethical framework will be provided, which is able to ward off the various issues that can be raised against the individual theoretical components of it, and a particular theistic extension of the theory will be provided which applies the central components of it within a theistic context.</p>
