The quote "O, brave new world that has such people in't!" expresses astonishment at the wonders of the world and the people within it. This line comes from Shakespeare's play "The Tempest," where it conveys both a sense of wonder and irony regarding societal progress and human behavior. The speaker marvels at the complexities of humanity, highlighting the duality of admiration and disillusionment present in new experiences.

This moment in the play reflects a broader theme of the natural versus the artificial and the complexities of human nature. The phrase suggests that while the world may seem captivating, it can also reveal darker truths about the people inhabiting it. Ultimately, Shakespeare invites readers to consider the balance between joy and discontent in the face of societal change.
