“后人类主义”作为一种跨学科思潮，近年来在科学技术论(STS)领域影响甚巨。侧身于该思潮之下，以拉图尔为代表的STS学者倾向于将能动性乃至欲望归因于非生物对象，陷入了技术去政治化困境。在对该困境予以病理学诊断的基础上，霍恩伯... 详细信息

“后人类主义”作为一种跨学科思潮，近年来在科学技术论(STS)领域影响甚巨。侧身于该思潮之下，以拉图尔为代表的STS学者倾向于将能动性乃至欲望归因于非生物对象，陷入了技术去政治化困境。在对该困境予以病理学诊断的基础上，霍恩伯格等学者认为有必要将马克思拜物教概念拓展到技术研究领域，从而将技术生成与发展嵌入全球交换系统脉络，即从政治经济学批判的层面上把握技术现象之本质：现代技术不过是一种全球剥削的和策略和手段。这样的技术拜物教批判进路，能为我们审视和颠覆西方科技霸权提供一定的理论支撑。
