This article explores Heidegger's later philosophy with regard to the problem of a philosophical interpretation of religious language. In what follows, I will draw upon the work of Wittgenstein and refer to the cosmological argument to read Heidegger in terms of a post-theistic understanding of religious language that avoids the shortcomings of both theistic realism and non-cognitivism. At the same time, I am proposing a new interpretation of Heidegger's later philosophy against this background. I will show that, in spite of (...) its hermeticism, Heidegger's later philosophy has a specific relevance to philosophy of religion that still needs to be explored. (shrink)
