 Kuhn’s emphasis on scientific practices, relative to the philosophical state of play in the 1960s, takes up some of the slack left by the rejection of strong realism. His emphasis on skilled practice may have been influenced by Michael Polanyi’s Personal Knowledge (1958), with its “tacit knowing” component, although Kuhn denied that he found Polanyi’s account appealing (see, e.g., Baltas et al., 2000, pp. 296f).
