 This argument shook compatibilists, and rightly so. The classical compatibilists’ failure to analyze statements of an agent’s abilities in terms of counterfactual conditionals left the compatibilists with no perspicuous retort to the crucial second premise of the Classical Incompatibilist Argument. And the Consequence Argument provides powerful support for this argument’s second premise. If, according to the Argument, determinism implies that the future will unfold in only one way given the past and the laws, and if no one has any power to alter its unfolding in that particular way, then it seems that no one can do other than she does.
