Abstract

ABSTRACTI defend the Interdependency Thesis, according to which rational evaluations of dispositions and actions are made in light of each other. I invoke a model of rationality that relies on various levels of consistency existing between an agent's reasons for adopting a moral disposition, the argument for the moral theory she endorses, her desires, disposition, and choice to be a moral person as reflected in the maxim she adopts. The Interdependency Thesis shows that we do not need to demonstrate the rationality of every morally required action in order to defeat scepticism fully.
