In "Lost in the Cosmos: The Last Self-Help Book," Walker Percy critiques the idea of the isolated individual as described by Descartes. Percy argues that true consciousness cannot exist in isolation, suggesting that human awareness is inherently connected to others and the world around us. This implies that the self cannot simply be a solitary thinking entity, as Descartes proposed.
Percy's perspective challenges the traditional notions of self-awareness by emphasizing the importance of relational experiences. He posits that humans are fundamentally interdependent, and our consciousness is shaped by social interactions, culture, and shared experiences, leading to a richer understanding of what it means to be human.
