Enkratic Rationality Is Instrumental Rationality*

Abstract

AbstractIt is widely agreed that there is a rational requirement, “Enkrasia”, which requires that you intend what you believe you ought to do. This paper argues that Enkrasia is not an independent requirement of practical rationality: it is a special case of the requirement to be instrumentally rational. I argue for this view of Enkrasia through an analysis of an all‐things‐considered belief about what you ought to do. Believing, all‐thing‐considered, that you ought to φ implies being settled on a set of options from which to take an option. I argue that this state of being settled on a set of options cannot be a matter of believing. Rather, it should be understood as intending that you do what you ought to do out of that set. If an all‐things‐considered belief implies such an intention, however, satisfying Enkrasia is a matter of satisfying the requirement to intend a necessary means to an end that you intend.
