The quote from Haruki Murakami's "The Strange Library" reflects on the individual journeys each person undertakes in life. It acknowledges that everyone has their unique thoughts, beliefs, and paths, emphasizing the inherent solitude of existence. This idea suggests that while we may share experiences, each person's understanding and direction are distinct, shaped by their personal circumstances and perspectives.
Moreover, the repetition of "The world follows its own course" serves to highlight the inevitability of life's progression, regardless of personal struggles. Each character is depicted as navigating their own fate, similar to the natural instincts of a starling. This notion reinforces the genre's themes of individuality and existential contemplation, inviting readers to reflect on their own life's course amidst an ever-changing world.
