In this chapter, I argue that Dialogical Self Theory (DST) represents a compelling answer to how to conceptualize the psychology of the self in today's world, when people increasingly are aware of more than one way to think, feel, and relate to others. DST envisions a self of plural voices. The chapters in this volume show intriguing applications of the theory, ranging from microlevel infant-caregiver interactions to macrolevel repercussions of globalization among Pacific island communities. I end by suggesting that the pliable nature of DST, illustrated in the chapter on an Indian social movement, is a strength. In my view, it fits with today's need for a new philosophy of social science. One-size-fits-all approaches are often too broad and too biased to adequately capture the complexities of human selves and relations. The challenge and opportunity that we face today is one of bridging universal theories with cultural ones--and the present volume can be read as one example of how to meet that challenge with respect to a psychology of the self.
