存在主义哲学关注世界的荒诞和个体的存在，石黑一雄小说描绘了生活在不同文化背景下的人们的生存困境，对存在价值、选择责任的思考有一种哲学意识。石黑一雄小说题材广泛，通过构建一个社会价值观交替多变的荒诞世界和异化的人际关系，探讨人物面对痛苦时如何用“自欺”进行自我防御，关注人物最终作出得以精神慰藉的选择，与萨特存在主义哲学观念相契合。石黑一雄小说具有有限视角的不可靠叙述、模糊的溯源式追忆、矫饰自欺的矛盾语言三个方面的写作特点，在与萨特的西方典型存在主义代表作《恶心》和《墙》对比下，二者相通之处彰显了石黑一雄与存在主义名家具有同样的写作技巧和人文关怀，相异之处体现出处于不同时代的石黑一雄存在主义书写在人物、语言、故事方面的独特性。石黑一雄的创作与其移民双重文化身份、复杂多变时代环境、个人成长经历息息相关，在如今发展日新月异的时代，石黑一雄存在主义书写既体现了精神慰藉和人本关注的个体价值，也展现出记忆反思和历史责任的集体价值，闪烁着存在主义哲学中人道主义的光辉。

Existentialist philosophy focuses on the absurdity of the world and the existence of individuals. Kazuo Ishiguro's novels depict the survival difficulties of people living in different cultural backgrounds, and have a philosophical awareness of the value of existence and the meaning of choice. His novels have a wide range of themes, exploring how characters use self deception to defend themselves against pain by constructing a absurd world with alternating social values and alienated interpersonal relationships. He focuses on how characters ultimately make choices that provide spiritual comfort, which is in line with Sartre's existentialist philosophy. Kazuo Ishiguro's novels have three writing characteristics: unreliable narration from a limited perspective, vague retrospective, and self deceptive contradictory language. Compared with Sartre's representative work of Western existentialism "Nausea" and "Wall"，the similarities between the two highlight Kazuo Ishiguro's profound writing skills and humanistic care, as well as the differences that highlight the characteristics of characters, language, and stories written in different eras of existentialism. The creation of Kazuo Ishiguro is closely related to his dual cultural immigrant identity , complex and ever-changing era , and personal growth experience. In the rapidly developing era, Ishiguro's existentialist writing has both individual values of spiritual comfort and humanistic concern, as well as collective values of memory reflection and historical responsibility, shining with the brilliance of humanitarianism in existential philosophy.
