Abstract
The Thomas Kuhn of "The Structure of Scientific Revolutions" is often seen as an idealist or Neo-Kantian, as holding a constructivist as opposed to realist position. A close reading of the texts in question, keeping in mind Kuhn's interests as a historian, doesn't support this position, though it uncovers other interesting metaphysical commitments. In particular, Kuhn sees a degree of complexity in the world that entails that there will often be some conventionality in our theories. Some reasons for the readings of Kuhn's as a "constructivist" are explored.
