The work of Libet and Wegner has nevertheless raised interesting and challenging questions concerning the role of consciousness in agency. Proponents of the standard theory often qualify the view with the claim that the relevant mental attitudes need not be consciously accessed in order to play the right role in the exercise of agency. When, for instance, Davidson (1978: 85–86) considered the example of an agent who adds some spice to a stew with the intention of improving the taste, he claimed that intentional agency requires only that the agent would have reasoned on the basis of the relevant attitudes that the action is to be performed, had he been aware of those attitudes at the time. Few, though, would be prepared to accept the view that all of our actions might be like this: initiated and guided by attitudes that are not consciously accessed at the time. This raises various questions that are rarely addressed. How often, or in what kinds of cases, should actions be preceded by conscious intentions or conscious reasoning? What kind of consciousness is required? In cases where the relevant attitudes are not consciously accessed, must they be accessible? And so forth.[21]
