Technologies are undeniably having a decisive, transformative impact on Earth, yet the currently prevailing empirically orientated approaches in the philosophy of technology seem unable to get to conceptual grips with this fact. Some thinkers have therefore been trying to develop alternative methods capable of clarifying it. This paper focuses on Vincent Blok’s call for rehabilitating an ontologically oriented approach. It reconstructs the rationale of his method as well as its key elements and structure. Elucidating Blok’s emphasis on the experience of (...) climate change, the paper clarifies his call for a terrestrial turn in the philosophy of technology. This turn is indisputably needed, but Blok’s conceptualisation of Earth is problematic: Apart from its speculative nature, it underestimates the impact of humans on Earth. Blok seeks to clarify how ontic phenomena, especially particular technologies, can have an ontological impact, but there is a friction between his Heideggerian concept of the world as grounding inner-worldly beings and the idea of technologies as founding a new world. Identifying the elements where the undoubtedly required ontological approach needs to be rethought, the paper suggests that we need more mundane conceptualisations of both Earth and the world, accompanied by more attention to ontic processes.

The point of departure of this article is the trend towards hybridisation in new technology development, which makes classical dichotomies between machines, human life and the environment obsolete and leads to the post-human world we live in today. We critically reflect on the post-human concept of the hybrid world. Although we agree with post-humanists that human life can no longer be opposed to machines but appears as a decentralized human-technology relation, alliance or network that constitutes a hybrid world, we ask (...) for a limit to hybridisation. After rejecting the concept of metabolism as such a limit, we explore the concept of the responsive conativity of material entities. The principle of conativity of material entities provides a materialist perspective on metabolism, which enables us to conceive material entities as self-assertive material entities that are differentiated from the environment. The principle of responsivity of material entities provides a materialist perspective on the post-human world in which material entities are responsive to each other and form alliances and networks. We propose to differentiate between the conativity and responsivity of material entities and propose the conativity of matter as a limit to hybridisation in the post-human world. (shrink)
