This brief essay introduces David Agler, Vincent Colapietro, and Robert Innis, who provide the major essays in this special issue of Tradition and Discovery devoted to putting together Michael Polanyi and Charles Sanders Peirce. It also provides an historiographical comment, suggesting that the two references to Peirce in Polanyi’s writing are quite puzzling and likely imply that Polanyi’s collaborators, rather than Polanyi, took an interest in similarities between the thought of Peirce and Polanyi.
