Abstract
According to a popular idea, freedom is grounded in orthonomy – the ability to be responsive to
normative demands. But how exactly must an agent’s action relate to their reasons in order for this
orthonomous relationship to hold? In this paper, I propose a novel explanationist answer to this
question. I argue that extant answers – causalism and modalism about orthonomy – fail because they
fail to account for the fact that intuitions about freedom and orthonomy track facts about
explanation. And these facts cannot be reduced to either causal or modal facts. Instead, I propose
that we should understand freedom as grounded in special accidentality-dispersing explanations in
terms of normative reasons. The resultant view is to be understood as following a Frankfurtian
intuition: only factors that explain action can be relevant to whether the action is free.
