 The distinction between knowledge-how and knowledge-that was brought to scrutiny in analytic philosophy by Ryle in his seminal The Concept of Mind (1949), where he raised some of the now classical objections to the so-called “intellectualist legend”: the view that knowledge-how amounts to knowledge-that. Ryle instead advocated an “anti-intellectualist” view of knowledge-how according to which knowledge-how and knowledge-that are distinct kinds of knowledge, and manifestations of knowledge-how are not necessarily manifestations of knowledge-that. This anti-intellectualism has been the received view among philosophers for a long time. Even psychologists and neuroscientists have explicitly appealed to Ryle’s classical distinction when discussing their empirical findings (e.g., Cohen &amp; Squire 1980; Anderson 1983). Nevertheless, in the last twenty years, a renewed interest by epistemologists in the nature of knowledge-how has brought new life to the debate, where new versions of intellectualism and anti-intellectualism have been developed and argued for. The debate is partly epistemological: is knowledge-how an altogether distinct kind of knowledge, different from knowledge-that? But it is also about a psychological question: what kind of psychological state is knowledge-how? The goal of this entry is to overview the debate between intellectualists and anti-intellectualists, while highlighting the implications of this debate for related questions concerning intelligence, cognition, language, and skills.
