This article explores the responses to nihilism offered by Jean-Luc Marion and Martin Heidegger. In particular, this paper offers a response to Steven DeLay’s ‘The vanity of authenticity’; DeLay’s text argues for the superiority of Marion’s response to nihilism through his notion of vanity and, further, argues that this supposed defeat of Heidegger by Marion lays the foundation for the theological turn in philosophy. This paper will instead suggest that Marion has not in fact surpassed Heidegger, that his concept of (...) vanity does not represent a meaningful innovation, and that his answer to nihilism/vanity through love is more similar to Heidegger’s response than either DeLay or Marion acknowledges. DeLay’s reading focuses on Heidegger’s Being and Time, but uses this reading to dismiss Heidegger’s work in its entirety. This paper will, instead, focus on Heidegger’s later work, which is ignored by both Marion and DeLay, offering particular attention to the shift in Heidegger’s response to nihilism as he increases his engagement with the thought of Friedrich Nietzsche and introduces the concept Gelassenheit, which generally replaces the terminology of authenticity after the 1940s.
