 In recent work, Carter and Pritchard (2015) have challenged intellectualism on this point. One such example they offer to this end involves testimony and skilled action. For example, suppose that a skilled guitarist tells an amateur how to play a very tricky guitar riff. Carter and Pritchard (2015: 801) argue that though the amateur can uncontroversially acquire testimonial knowledge from the expert that, for some way w that w is the way to play the riff, it might be that the expert, but not novice, knows how to play the riff. Further, they suggest that whilst the amateur is better off, with respect to the aim of playing the riff, than he was prior to gaining the testimonial knowledge he did, he would likewise be better off further—viz., he would have something even more valuable—if he, like the expert, had the lick down cold (something the amateur does not have simply on the basis of his acquired testimonial knowledge) (Ibid: 801).
