Many of us feel a pressing desire to be different-to be other than who we are. Self-conscious, we anxiously perceive our shortcomings or insufficiencies, wondering why we are how we are and whether we might be different. Often, we wish to alter ourselves, to change our relationships, and to transform the person we are in those relationships. Not only a philosophical question about how other people change, self-alteration is also a practical care-can I change, and how? Self-Alteration: How People Change Themselves across Cultures explores and analyzes these apparently universal hopes and their related existential dilemmas. The essays here come at the subject of the self and its becoming through case studies of modes of transformation of the self. They do this with social processes and projects that reveal how the self acquires a non-trivial new meaning in and through its very process of alteration. By focusing on ways we are allowed to change ourselves, including through religious and spiritual traditions and innovations, embodied participation in therapeutic programs like psychoanalysis and gendered care services, and political activism or relationships with animals, the authors in this volume create a model for cross-cultural or global analysis of social-self change that leads to fresh ways of addressing the ‘self’ itself.
