 Several philosophical considerations conspire to make TT a compelling view of FP. In his seminal “Empiricism and the Philosophy of Mind” (1956), Wilfrid Sellars aired the idea that our understanding of mental states is, essentially, theoretical. In an engaging bit of philosophical anthropological fiction, he famously mused about how our Rylean ancestors, who were as yet behaviorists, might have first fashioned an understanding of thoughts as inner episodes. He invented a mythical Jones who modeled inner thoughts on overt speech acts, imagining that the former could, just like the latter, be cited in the explanation of action. Assuming that reasons are the inferred causes of action, it is but a short step to thinking that explaining action using a schema that goes beyond what is merely given in another’s outward responses is necessarily a kind of theoretical activity.
