ABSTRACT This article draws on labor history and science and technology studies to propose a method, and to provide an example, of historical analysis that is responsive to the conceptual categories that arise out of ethnographic accounts of individuals’ lived experiences. Using an ‘ontological tool-box’, this article follows various enactments of consumer appliances and, along with them, ideas of what it is to be a productive worker in a small appliance repair shop and across the practices of certain institutions of disciplinary power. Through an ethnographic and ontological analysis of repair in the Philadelphia neighborhood of Kensington, this article reveals that, rather than being inevitable or essential, all the categories used to organize our world, whether referent to identities or objects, are both constituted by and constitutive of a complex set of social relations and ideological priorities, which even historians are implicated in reproducing.

修复价值：费城维修店的历史、民族志和材料本体论

摘要 本文借鉴劳动史和科学技术研究，提出了一种历史分析方法并提供了一个例子，该方法对从个人生活经历的民族志描述中产生的概念类别做出反应。使用“本体论工具箱”，本文跟踪消费电器的各种制定，并与它们一起提出了在小型家电维修店和某些纪律权力机构的实践中成为一名生产工人是什么的想法。通过对肯辛顿费城附近修复的人种学和本体论分析，本文揭示了用于组织我们世界的所有类别，无论是指身份还是对象，都不是不可避免的或必不可少的，
