The concept of ‘the Anthropocene’ as a new human-induced geological epoch has made its way into IR. Debates have recently arisen between ‘post-humanists’ stressing its destruction of subject-object binaries and ‘New Anthropocentrists’ arguing that it increases the importance of the human being as planetary steward. This article moves beyond these debates to question a strange but unexplored foundation that underlies the basic discourse of the Anthropocene: the assertion that humanity must be grouped together as a collective species, ‘anthropos’, or planetary ‘We’. Using the philosophy of Martin Heidegger, it argues that the Anthropocene reveals a new and deeper shift in human subjectivity, moving from an individualistic Cartesian ‘I’ to a collective and planetary ‘We’. This argument is made in three steps. First, today's common treatment of humanity as a collective whole in Anthropocene literature is examined. Second, it details how transformations in subjectivity occur by shifting the historical boundaries of our most fundamental notion of certainty – the ‘subiectum’ – and how the technologies of Earth System Science (ESS) subtly facilitate this shift today. Finally, the article argues how this subjective transformation from the ‘I’ to the ‘We’ results from the temporal, spatial, and existential incalculability and uncertainty of the Anthropocene, thereby fostering the rise of certainty in new forms of conflictual identity politics.

我不确定，但我们不是：人类世的新主体性

“人类世”的概念作为一个新的人为地质时代已经进入了国际关系研究。最近，“后人文主义者”强调其对主客二元的破坏和“新人类中心主义者”之间出现了争论，他们认为这增加了人类作为行星管家的重要性。本文超越了这些争论，质疑了一个奇怪但尚未探索的基础，它构成了人类世基本话语的基础：人类必须被归为一个集体物种、“人类”或行星“我们”的断言。使用马丁海德格尔的哲学，它认为人类世揭示了人类主体性的新的和更深层次的转变，从个人主义的笛卡尔式的“我”转变为集体和行星的“我们”。这个论点分三个步骤进行。首先，今天' 人类世文学中对人类作为一个集体整体的共同对待进行了研究。其次，它详细说明了如何通过改变我们最基本的确定性概念的历史边界来发生主观性的转变——'subectum'– 以及地球系统科学 (ESS) 技术如何巧妙地促进当今的这种转变。最后，本文论证了这种从“我”到“我们”的主观转变如何源于人类世的时间、空间和存在的不可计算性和不确定性，从而促进了新形式的冲突身份政治中确定性的兴起。
