The dominant account of interdisciplinary integration mobilizes linguistic metaphors such as bilingualism or the learning of new languages. While there is something right about these linguistic metaphors, I urge caution about philosophical confusions that can arise in the absence of careful scrutiny of how our language relates to the world. Drawing particularly on Ludwig Wittgenstein's insights in his "Philosophical Investigations," I recommend four therapies to treat confusions that may arise when we uncritically reflect on the relationship between language and the world. Interdisciplinary scholars could benefit from careful attention to the ways that (1) understanding is a social deed, (2) language is a set of tools, (3) analysis into simple concepts loses meaning, and (4) the "grammar" of different regions of language can complicate translation. I then revisit what is correct about linguistic metaphors and emphasize that the challenge of integration is agreeing to a way of organizing social practices and prioritizing social goals, or what Wittgenstein called a "form of life." These closing reflections shift from the therapeutic, anti-theoretical reading of Wittgenstein's later philosophy to a reading that recognizes a positive project in his work.
