Hardcover. NY, Doubleday and Co., 1st, 1966, Book: Very Good, Dust Jacket: None, Hardcover in green cloth with black cloth spine, gilt lettering on spine. 108 pages, green endpapers. "I shall reconsider human knowledge by starting from the fact that we can know more than we can tell," writes Michael Polanyi, whose work paved the way for the likes of Thomas Kuhn and Karl Popper. The Tacit Dimension argues that tacit knowledge--tradition, inherited practices, implied values, and prejudgments--is a crucial part of scientific knowledge. A bright, clean first printing of this classic, lacking the dust jacket.
