The aim of this book is to examine new forms of resistance to social injustices in contemporary Western societies. Resistance requires agency, and agency is grounded in notions of the subject and subjectivity. It is a premise of this book that new and/or reconstructed forms of subjectivity are required to challenge social relations of subordination and domination. Subjectivity is primarily based on lived experience. While subjectivity is sometimes used to explore individualistic strategies for personal meaning, we argue that subjectivity is central to political struggles against regimes of power. Thus, understanding how subjects are constituted is important in fostering the capacity of critical reflection and social transformation. Our aim is to understand the relationship between subjectivity and the wider social order. The relationship between the psyche and society is one of the most challenging issues facing social theory. While there is a variety of theoretical approaches to subjectivity, those that explore the links between the subject and society are the most promising in developing strategies for resistance. In this introductory chapter, we review and interrogate what we believe are the most important theoretical approaches to subjectivity, drawing upon Marxism, critical theory, feminism, postcolonialism and post-structuralism. Our aim in this book is not to develop a new theory of subjectivities. Rather, we are more concerned with investigating how diverse subjectivities are constructed and reconstructed.
