In "Lost in the Cosmos: The Last Self-Help Book," author Walker Percy explores the profound strangeness of human existence compared to the vast mysteries of the universe. He emphasizes that despite the countless celestial phenomena like quasars and black holes, humans remain the most perplexing entities. This creates a sense of wonder about our own identity and existence within the grand cosmic landscape.

Moreover, Percy raises an intriguing point about self-awareness, suggesting that it's paradoxically easier to learn intricate details about distant astronomical objects, such as the Crab Nebula, than to fully understand oneself. This highlights the complexities of human consciousness and the challenges of introspection, inviting readers to reflect deeply on their own identities and the nature of self-knowledge.
