Abstract

This paper enhances postnatural environmentalism (represented by Steven Vogel) by highlighting and incorporating selected concepts from Martin Heidegger's ontology. In particular, I examine Heidegger's detailed analysis of the affinity between phusis and techne, the critique of 'replaceability', the problem of 'proper use', and his earlier concept of a tool structure. This analysis is aimed at grounding the metaphysical and ethical significance of technical artefacts. It shows that Heidegger can support postnatural environmentalism's claim that artefacts should not be jettisoned by environmental thinking because that leads to reckless treatment of them. Exploration of these issues also contributes to environmental interpretations of Heidegger's philosophical legacy, which were limited to natural beings.
