Abstract
In this paper, I distinguish causal from logical versions of the direct argument for incompatibilism. I argue that, contrary to appearances, causal versions are better equipped to withstand an important recent challenge to the direct-argument strategy. The challenge involves arguing that support for the argument’s pivotal inference principle falls short just when it is needed most, namely when a deterministic series runs through an agent’s unimpaired deliberations. I then argue that, while there are limits to what causal versions can accomplish, they can be used to buttress the ultimacy argument, another important argument for incompatibilism.
