Anscombe’s “Causality and Determination” is often cited in the contemporary free will debate, but rarely discussed in much detail. It’s main contribution, it is thought, is the defense of an alternative to deterministic causation, thus clearing the way for an incompatibilist analysis of free actions in terms of probabilistic causation. However, in this paper I will show that the contemporary probabilistic analysis of free action actually stands in direct conflict with Anscombe’s lecture. Instead, I will argue, its true value for (...) incompatibilist accounts of free will lies in Anscombe’s thought that there are various fundamentally different kinds of causality. This variety, I argue, allows for a revised conception indeterminism and an understanding of free will as the manifestation of a particular sort of agent-causal power. (shrink)
