Garfield traces arguments against the existence of a self primarily through 7th century Indian Buddhist scholar Candrakīrti and 18th century Scottish philosopher David Hume, and explores where many other philosophers hit or miss the mark along the way. The book is a surprisingly accessible read about a complex topic with perhaps the exception of a couple more in-depth chapters that develop arguments to further his conclusion: you don't have a self, and that's a good thing.
Garfield starts with the idea of self from ancient India: the ātman is at the core of being. A distinct self feels necessary to understand our continuity of consciousness over time (diachronic identity) and our sense of identity at a single time (synchronic identity). A self gives us a way to explain our memory and allows for a sense of just retribution when we're wronged. We feel a unity of self to the extent that it's hard to imagine it's not so.
