Abstract
If the world in which we are intentionally involved is threatened by climate change, this raises the question about our place on Earth. In this article, we argue that the ecological crisis we face today draws our attention to the Earth as ontic-ontological condition of our being-in-the-world. Because the Earth is often reflected upon in relation to human existence, living systems or material entities in the philosophical tradition, we argue for an ontological concept of the materiality of the Earth as un-correlated being in this article. We develop five principles of the materiality of the Earth: the conativity, non-identity, responsiveness, performativity and eventuality of the Earth. We will argue that it is this notion of Earth that matters to us in the age of global warming.
