Summary
Analysis
Zarathustra encounters no one else and enjoys his solitude. Just before noon, however, he takes a nap in the shade of a gnarled tree, content. His soul is weary of journeying, and he rests in the perfect stillness of the world, seemingly for an eternity. After a few moments, however, he stirs himself from his intoxicated state, not having slept for long.
Noontide symbolizes humanity’s midway point as it evolves into something greater than its current iteration. Having gathered various higher men, Zarathustra rejoices and rests in the knowledge that humanity is closer to the Superman.
