 One of Stein’s posthumous publications was a scholarly essay, “Ways to Know God”, (in Stein 1993) on the Christian mystic, Pseudo-Dionysius the Areopagite. For Stein, Dionysius’ mystical theology is not a scientific discipline but a way to speak about God. Just as perception always points beyond itself, similarly our experience of the world points beyond itself to its divine source (1993: 27[99]). This world is the basis for natural theology. God is the “primary theologian” (Ur-Theologe; 1993: 27[100]) and the whole of creation is his symbolic theology. Affirmative theology is based on the analogia entis; negative theology is based on the dissimilarity between creatures and God. For Stein, negative theology “climbs the scale of creatures” to discover that at each level God is not found there: “We draw near to God by denying what he is not” (1993: 19[88]).
