Panaccio's chapter takes on the issue of objects of thought in a purely nominalist setting, comparing Ockham's and Buridan's accounts of the same questions. The chapter argues that whereas William of Ockham can legitimately be branded as a linguistic externalist, Buridan's considered position with respect to linguistic meaning is a form of internalism. In this discussion, much hinges on the precise understanding of the medieval doctrine of imposition, the mechanism whereby written and spoken symbols are subordinated to acts of thought, and how this mechanism relates individual acts of thought to their publicly recognized objects.
