Abstract: In Never Let Me Go, Kazuo Ishiguro tells the tragic story of cloned humans living under the shadow of disciplinary mechanisms who, without identity, become organ donors. Cloning technology deprives cloned individuals of the dignity and rights they are entitled to as living beings, exposing the moral blind spots and ethical dilemmas of natural persons in the face of technology. The conflict between technological rationality and moral rationality is the fundamental reason underlying the deviation of technological development from the ethical course, and the lack of individual identity and the distortion of ethical relationships make it difficult for individuals to find the meaning and value of life, thereby eroding the foundation of human existence. Kazuo Ishiguro tells us that every subject of life should be entitled to equal value and respect, that the writers should not only pay attention to technological progress and the ethical, moral, and humanistic concerns behind it, but also examine whether development of technology tramples on the dignity of life. Only by maintaining the balance and coordination between technological rationality and moral rationality can humanity overcome ethical crises and survival dilemmas to achieve true civilization progress and social development.

Key words: Kazuo Ishiguro, Never Let Me Go, disciplinary mechanism, ethical dilemma, posthuman reflection
