This book is an important collection of essays by Roy Bhaskar, the founder and pioneer of critical realism. Organised into sections including the philosophy of science, the philosophy of social science, ideology critique and dialectic and metareality, it is the essential introduction to this important school of philosophy. In addition to offering some of Bhaskar’s most important discussions of these subjects, it also includes detailed introductions to each section which aim to elucidate some of Bhaskar’s key concepts and theories. It therefore constitutes essential reading for students and scholars who are keen to gain a deeper understanding of Bhaskar’s seminal works and philosophy.
