In the Unended Quest, Karl Popper deals with the grand old philosophical issues, which in Popper's opinion always needed to be restated: physical theories, the body-mind problem, individuality, freedom. In this autobiography, Popper does not describe his personal circumstances as much as he does the important stimuli which had an enduring effect on his intellectual development and the philosophical problems which he dealt with in the course of his life. Although the focus is not on his personal life, there are some individual sections in the book which describe the initial situations or the concrete experiences which led to Popper's critical observations. Thus the Unended Quest can be regarded as an introduction to the work of one of the major philosophers of the 20th century.
