Since the 1970s, critical realism has grown to address a range of subjects, including economics, philosophy, science, and religion. It has become a complex and mature philosophy. Enlightened Common Sense: The Philosophy of Critical Realism looks back over this development in one concise and accessible volume. The late Roy Bhaskar was critical realism’s philosophical originator and chief exponent. He draws on a lifetime’s experience to give a definitive, systematic account of this increasingly influential, international and multidisciplinary approach. Critical realism’s key element has always been its vindication and deepening of our understanding of ontology. Arguing that realist ontology is inexorable in knowledge and action, Bhaskar sees this as the key to a new enlightened common sense. From the definition of critical realism and its applicability in the social sciences, to explanation of dialectical critical realism and the philosophy of meta Reality, this is the essential introduction for students of critical realism.
