AbstractThis article argues for four interrelated claims: (i) Metaphilosophy is not one sub‐discipline of philosophy, nor is it restricted to questions of methodology. Rather, metaphilosophical inquiry encompasses the general background conditions of philosophical practice. (ii) These background conditions are of various sorts, not only those routinely considered “philosophical” but also those considered biographical, historical, and sociological. Accordingly, we should be wary of the customary distinction between what is proper (internal) and merely contingent (external) to philosophy. (iii) “What is philosophy?” is best understood as a practical question concerning how members of different philosophical sub‐communities identify what is pertinent to their respective activities and self‐conceptions. (iv) Given (i)–(iii), understanding what philosophy is requires us to take more seriously the social‐institutional dimension of contemporary philosophical practice.
