In H.G. Wells' "The Island of Doctor Moreau," the narrator wrestles with the chaos and moral dilemmas present in the world around him. The quote, "I must confess that I lost faith in the sanity of the world," reflects a deep disillusionment with humanity and its actions, particularly in the context of scientific ethics and the consequences of playing God. This sentiment resonates throughout the novel, as the protagonist witnesses the horrifying results of Moreau's experiments on animals, leading to a critique of unchecked scientific ambition.

The story explores themes of civilization versus savagery, and the fragility of human identity. As the narrator grapples with the surreal and nightmarish reality of the island, his loss of faith highlights a broader existential crisis. The reader is urged to ponder the nature of humanity and the implications of distorting the natural order, questioning what it truly means to be sane in a world fraught with moral ambiguity and ethical violations.
