C. P. Snow's "The Two Cultures" controversially contrasted science and literature, suggesting that neither scientists nor literary intellectuals have much in common with, and seldom bother speaking to, the other. Responding to Snow, Michael Polanyi argued that specialization has made modern culture, not twofold but manifold. In his major work, "Personal Knowledge," Polanyi explained that branches of modern culture have "personal" knowing and knowledge "in common", and there is extensive cross-pollination of ideas. He also, in this book, saw the branches of culture as disparate intellectual frameworks that are "divorced" from one another. (Contains 9 notes.)
