In Rebecca Goldstein's "Plato at the Googleplex: Why Philosophy Won't Go Away," the author explores the enduring relevance of philosophical thought in contemporary life. One striking quote from the book is "Thinking is the soul speaking to itself," which emphasizes the introspective nature of human consciousness. This perspective suggests that our thoughts and reflections are integral to understanding our own existence and identity.

The quote encapsulates the essence of philosophical inquiry, highlighting that self-reflection is a crucial part of being human. Goldstein argues that even in a modern world increasingly focused on technology and empirical knowledge, philosophy remains vital. It serves as a tool for individuals to connect with their inner selves and contend with profound questions about life, meaning, and existence.
