ABSTRACT
This chapter seeks a strategic deployment of Heidegger's Seinsfrage as a theological contribution to the understanding of both human and non-human nature. It begins by sketching the background of Heidegger's relationship to theology and the reasons why his thought led him to develop alternative strategies in the effort to re-think the encounter between 'lived faith' and an adherence to dogmatic metaphysical concepts. The chapter engages with Heidegger's identification of the grounding principle of Western theological metaphysics as ontotheology; a metaphysical principle which he also thought determined the history of Productionist Metaphysics and which has given rise to an age of technological Enframing. It critically assess Heidegger's attempt to overcome metaphysics and the possibility of non-metaphysical thinking, leading to a reappraisal of his strategy as the quest to deconstruct the predominant Western metaphysical tradition in order to think in an other way, but which retains metaphysical concepts and determinations.
