From Formalism to Psychology: Metaphilosophical Shifts in Wilfrid Sellars’s Early Works

When discussing Wilfrid Sellars’s philosophy, very little work has been done to offer a developmental account of his systematic views. More often than not, Sellars’s complex views are presented in a systematic and holistic fashion that ignores any periodization of his work. I argue that there is a metaphilosophical shift in Sellars’s early philosophy that results in substantive changes to his conception of language, linguistic rules, and normativity. Specifically, I claim that Sellars’s shift from a formalist metaphilosophy to one more closely aligned with psychology allows for the construction of a normative conception of language. My central claim is that without his abandonment of earlier metaphilosophical commitments, Sellars could not hold what I call an external conception of normativity. It is this move away from a formalist notion of philosophy that allows Sellars to construct a normative picture of language. I conclude that because this substantive shift in philosophical commitments results from changes in Sellars’s metaphilosophical views, there is insight to be found in a meticulous periodization of his work.
