Identity as a subject for analysis and discussion, and as a lived reality for all of us, has never been more complex and multi-faceted. Uneven though they are, technological advances and globalization change the ways people understand their identities. Under these conditions, our identity escapes from disciplinary bounds to a place where the sophistication and complexity of its existence have to be matched by openness, analyses, and reflections that also transcend disciplinary categorization. This book attempts analyses of this kind, and its structure is designed to be sympathetic to this aspiration in that it moves from disciplinarity through multidisciplinarity to transdisciplinarity and extradisciplinarity.
