Introduction

Since the publication of Roy Bhaskar's A Realist Theory of Science in 1975, critical realism has evolved as one of the new developments in the area of philosophy of natural and social science that offers an alternatively fresh view of existing theories, including positivism and postmodernism. Bhaskar's intellectual movement, which is now fully international and multi-disciplinary, and continues to influence the philosophies of natural and social science, has transformed into “dialectical critical realism” (DCR) and the philosophy of “metaReality.”
