This document provides an introduction to the TOK (Theory of Knowledge) course. It outlines several key concepts including areas of knowledge, ways of knowing, and two metaphors for the course - that each area of knowledge can be thought of as a culture, and that maps are useful but imperfect representations. It presents some sample claims that could be discussed and analyzed through a TOK lens. It also references the film The Truman Show as a example that could provoke discussion around questions of knowledge, truth, and perception of reality.
