If the dialogical self is an extended position repertoire in time and space, then it must have features of both simultaneity and succession. This conceptualization presents significant challenges for theory building, and is addressed in this chapter. The chapter considers recent developments in positioning theory and presents an overview and synthesis of positioning processes. It draws particularly on the recent work of H.J.M. Hermans, as well as other scholars. The chapter takes the liberty of summarizing their ideas along with other recent contributions to positioning theory. It looks at the historical processes captured in the premodern, modern and postmodern models of the self; it is tempting to link dialogical self theory (DST) explicitly to the postmodern model DST. The chapter focuses on the concepts of ambiguous third position and dialogical triad, arguing that they provide important tools for conceptualizing both integration and differentiation in the formation of a dialogical self.
