In this paper, I discuss a problem for Kant's strategy of appealing to the agent qua noumenon to undermine the significance of determinism in his theory of free will. I then propose a solution. The problem is as follows: given determinism, how can some agent qua noumenon be 'the cause of the causality' of the appearances of that agent qua phenomenon without being the cause of the entire empirical causal series? This problem has been identified in the literature (Ralph Walker (...) provides what is perhaps the most dramatic presentation of it). But it has never received an adequate solution. In this paper, I argue that Walker’s objection is only decisive if we must understand our responsibility as responsibility for events, but not causal laws. I argue that we need not interpret Kant's theory in this way. I demonstrate that each agent qua noumenon could be responsible for "limited instantiation scope" causal laws which necessitate only the phenomenal actions of that same agent qua phenomenon. Part of this project involves showing that there are relevant constituents of actions which are "rare" enough to instantiate such laws. I demonstrate that, on Kant's view, events in agents’ bodies are not rare enough, but events in agents’ phenomenal souls are. (shrink)

Transcendental freedom consists in the power of agents to produce actions without being causally determined by antecedent conditions, nor by their natures, in exercising this power. Kant contends that we cannot establish whether we are actually or even possibly free in this sense. He claims only that our conception of being transcendentally free involves no inconsistency, but that as a result the belief that we have this freedom meets a pertinent standard of minimal credibility. For the rest, its justification depends (...) on practical reasons. I argue that this belief satisfies an appropriately revised standard of minimal credibility, but that the practical reasons Kant adduces for it are subject to serious challenge. (shrink)
