Polyani, Michael; Sen, Amartya (2009). The Tacit Dimension. University Of Chicago Press; Reissue edition. ISBN 978-0-226-67298-4.

In "The Tacit Dimension", Michael Polanyi and Amartya Sen explore the concept of tacit knowledge, which refers to knowledge that is difficult to articulate, often learned through experience, and not easily communicated or transferred to others. The authors argue that tacit knowledge plays a crucial role in many areas of human activity, including science, art, and politics, and that it can be acquired through participation in communities of practice.
