We present our previous formalization of virtue ethics Vzf based on Zagzebski Exem- plarist Virtue Theory and evaluate how well it adheres to a set of conditions laid for virtue ethics out by Alfano. Our formalization is based on planning and learning and is cast in a formal logic, a cognitive calculus (which subsumes a quantified first-order logic), that has been previously used to model robust ethical principles, in both the deontological and consequentialist traditions.
