In "Mason & Dixon," Thomas Pynchon presents a metaphorical comparison between the Earth and the human body. He suggests that the Earth possesses a structure akin to human anatomy, comprising a series of invisible lines or meridians connected by specific points. This illustration draws on the principles of traditional Chinese medicine that utilize these points for therapeutic interventions.

Pynchon's depiction emphasizes the interconnectedness of the Earth and the human experience, portraying both as complex systems that can be enhanced through specific actions, such as the insertion of acupuncture needles. This highlights a deeper philosophical perspective on how we engage with the natural world, suggesting that understanding its "body" can lead to improved harmony and health.
