This document discusses avatars and online identity in virtual worlds like Second Life. It begins by defining avatars as manifestations rather than representations, and explains how avatars allow users to explore different identities and aspects of themselves. It notes that online identities can be fluid and change over time. The document then discusses how different avatar forms can receive different responses, shaping distinct identities. It questions what is considered "real" - the physical self or inner identity. Finally, it discusses implications like how online worlds allow focus on inner identities rather than outward appearances, and how online experiences may transfer to impact real-life identities.
