Abstract This paper addresses the question of whether two-way powers – powers to act in some way (to ɸ ) or to refrain from acting in that way (to refrain from ɸ -ing) – are causal powers. That is, the question is whether the power to ɸ or refrain from ɸ- ing could amount to the power to cause an effect of some kind, E , or refrain from causing an E -effect. It is argued that, for the incompatibilist regarding two-way powers, though not for the compatibilist, two-way powers cannot be causal powers. But an alternative account of two-way powers as powers of non-causal determination is presented as available and favourable.
