This document discusses the concept of alterity, or otherness, from an art historical perspective. It begins by defining alterity as how Western culture historically viewed the self in contrast to others. It then explores how postmodernism emphasizes relationships between self and other through figures defined by terms like alterity, absence, and uncertainty. The document examines how anthropology and feminist discourses have discussed gendered and racialized others. It also analyzes how artworks have addressed themes of doubles, doppelgängers, virtual worlds, and technologies in relation to notions of self and alterity.
