Against Logical Versions of the Direct Argument: A New Counterexample

Here I motivate and defend a new counterexample to logical (or non-causal) versions of the direct argument for responsibility-determinism incompatibilism. Such versions purport to establish incompatibilism via an inference principle to the effect that non-responsibility transfers along relations of logical consequence, including those that hold between earlier and later states of a deterministic world. Unlike previous counterexamples, this case doesn't depend on preemptive overdetermination; nor can it be blocked with a simple modification of the inference principle. In defending this counterexample, I show that van Inwagen's technical notion of being partly responsible for a state of affairs, which figures in his statement of the principle, is problematic
