The term “tacit knowing” or “tacit knowledge” was first introduced into philosophy by Michael Polanyi in 1958 in his magnum opus Personal Knowledge. He famously summarizes the idea in his later work The Tacit Dimension with the assertion that “we can know more than we can tell.”.[1] He states not only that there is knowledge that cannot be adequately articulated by verbal means, but also that all knowledge is rooted in tacit knowledge in the strong sense of that term.
