Abstract

This article explores the various ways in which Charles Peirce adapted some of John Duns Scotus’s ideas for his own philosophical purposes. Extending beyond the much-explored territory defined by Peirce’s and Scotus’s common embrace of scholastic realism, the purpose here is to identify and explore a variety of ways in which Peirce’s thought may have been shaped by Scotus’s conclusions. Peirce’s Scotism can be discerned in the careful examination of a diversity of topics: the pragmatic consequences of a commitment to realism, semiosis conceived as an essentially ordered process, abduction as form of abstraction, and the essentially practical nature of theological inquiry are the particular topics emphasized here. In each instance, there is clear evidence that Scotus’s original conceptions have been creatively transformed within the context of Peirce’s philosophy.
