Since Erik Erikson's clinical and psychohistorical writings of the 1950s and 1960s, the notion of identity has served as a bridge between formulations of personality development and the psychosocial aspects of cultural cohesiveness. More recently, under the influence of a postmodern perspective, clinical writers have questioned the notion of a stable, integrative identity or self as an organizing agent in human behavior. In the area of gender identity, particularly, feminist theorists have criticized the construction of polarized gender identities both for (...) their psychological inadequacy and their cultural bias.A parallel line of criticism has developed at the cultural or historical level. Writers such as Benedict Anderson and Ernest Gellner have effectively contrasted the shallow ideological and historical roots of nationalism with the effort to base national identity on the appeal to tradition and continuity. Other writers have emphasized the heterogeneous condition of the contemporary nation in a postcolonial world. They contrast a static concept of cultural or national identity to a more fluid notion which incorporates the ongoing process of displacement that, they argue, characterizes national discourse. The identity structures that emerge from this critique, both within a clinical and a historical setting, are more ambiguous and unstable, and reflect the heterogeneous experience of contemporary culture.World historians such as William McNeill and Theodore von Laue have cited the boundedness of historians within their own cultural identities as a significant obstacle to the development of an intercultural approach to world history. These postmodern reformulations of identity theory challenge the notion of cultural boundedness by emphasizing the discontinuities endemic to modern life and the inescapably plural character of contemporary identity.
