Direction of fit theories usually claim that beliefs are such that they “aim at truth” or “ought to fit” the world and desires are such that they “aim at realization” or the world “ought to fit” them. This essay argues that no theory of direction of fit is correct. The two directions of fit are supposed to be determinations of one and the same determinable two-place relation, differing only in the ordering of favored terms. But there is no such determinable because of ineliminable asymmetries between the way that beliefs “aim at truth” and the way that desires “aim at realization.” This essay traces the ills of direction of fit theory to a misunderstanding of Anscombe and proposes a cure that distinguishes theoretical and practical thought by appeal to a distinction between thought in the form of a state and thought in the form of an event.

Helen Steward argues that action is the exercise of a two-way power, and that if there are actions, then determinism is false. The concept of a two-way power has its roots in Aristotle, but Aristotle’s conception of a two-way power is compatible with determinism. I explain the differences between Steward and Aristotle’s conceptions of two-way powers and point out how a compatibilist opponent to Steward’s argument could exploit an Aristotelian conception of two-way powers. This leads to a dialectical stalemate between the imagined Two-Way Compatibilist and the Agency Incompatibilist. In conclusion I sketch a neutral conception of action as the exercise of a two-way power that sidesteps the dialectical stalemate whilst retaining the best aspects of Steward’s account of animal agency.
