Until recently, Wilfrid Sellars’s connection to pragmatism was seen mostly as tangential by analytic pragmatists influenced by him and by anti-analytic ‘classicalist’ pragmatists alike. Recent scholarship in the history of pragmatism, however, has begun to recover him as a genuine member of that tradition. Similarly, John Dewey, whom no one would challenge as a genuine pragmatist, is often seen by classicalists as fundamentally opposed to the kind of analytic philosophy that Sellars represents and by analytic pragmatists as having some good ideas but not very successfully bringing them to fruition. This too is conventional wisdom best overturned. A fresh-eyed interpretation of Dewey’s work shows that Dewey is a major influence on the development of Sellars’s pragmatism, namely that Sellars’s account of conceptual intentionality in nature is both a critical reaction to and development of Dewey’s naturalistic view of conceptual meanings. In particular, Sellars’s account of rule-following behavior and pattern-governed behavior builds upon Dewey’s account of the relationship between conceptual activity in reasoned discourse and intelligent habits of action in ordinary affairs. By illuminating this influence of Dewey on Sellars, we see that Sellars and Dewey are in the same pragmatist tradition of thought about mind in nature. Further, appreciating this influence shows that Sellars’ view departs from an important tenet of Dewey’s pragmatism, and in doing so makes his view vulnerable to an objection that Dewey’s is not.
