  What is clear is that there are two main varieties of internalist view, each of which faces its own class of problems. Most internalist views encounter the Central Problem, and hence have difficulty in allowing for some of the important reasons that we pre-theoretically are inclined to think that there are. Though other arguments have been offered against them, this challenge is at the heart of their difficulties. We saw that some Counterfactual versions of internalism avoid the Central Problem, by claiming that the relevant counterfactuals are not grounded in any features of agents’ actual psychologies, but rather are explained in some other way. The challenge facing these views is to provide such an explanation without collapsing into triviality, as with the view that the relevant counterfactual condition is ‘that the agent is motivated by all of her reasons’.
