This paper extends well-established arguments for the liberal potential of vocational education by advocating for the "necessity" of craft learning in a liberal education curriculum. The case for the necessity of craft learning in liberal education is established in two parts, the first looking toward Aristotle and the second toward Heidegger. First, ideas from Aristotle are employed to articulate a vision of liberal education as that which supports the performance of our characteristic human activity. The paper then splits with Aristotle to suggest that such activity is not defined by rational contemplation, but rather by the circumspective engagement with materials through which our being-in-the-world becomes apparent to us. If, as Heidegger suggests, these practical engagements demonstrate our most fundamental mode of encountering the world and one another, then any liberal education focused on the fulfillment of our potential for understanding must include some craft learning by necessity.
