A companion to Dr Hay's The Theory of Knowledge. A Coursebook, this guide presents a more sophisticated approach to epistemology with an emphasis on the interactions between Science and Philosophy from the 17th century to date. Using the classic debate between the empiricist and rationalist traditions as a framework, Clare Hay follows the developments of theory of knowledge up to the twentieth century, and the intersection points of epistemology with other branches of philosophy are also considered. The book's unique strength lies in the correlation between the developments of philosophical thought and the rise of modern science. As the author suggests, 'studying philosophy is one of the most extraordinary intellectual journeys', and this comprehensive yet accessible book will provide the useful signposts for both the student and general reader.
