The concept of the other is a fundamental ethical concept. The approach of ethics through a reflection on the concept of the other challenges traditional concepts of modern ethics which tend to either exclude 'the other' or have an exclusively negative conception of it. The exclusion of otherness not only concerns women in general who were conceived as the irrational other of the rational man, but also other men, who developed a different rationality than the Occidental one. The book considers the opening towards sex-gender-differences, but also cultural and social differences as a necessary condition for rethinking Western philosophy. Thus the aim of this volume is to take up the possibilities a reflection on the other in its otherness offers for contemporary philosophy. This not only allows for a critique of the solipsism of modern Occidental philosophy but also for developing new approaches in ethics as well as an ethics of thinking. The volume brings together feminist philosophers from the US, Canada, Australia and Europea, all of them sharing a phenomenological approach to philosophical questions.
