Abstract
Based on Merleau-Ponty's description of nature as that on which we ultimately rely, this essay cultivates the thought that this description also fits an idea of God and therefore of Deus sive Natura. Guided by an outline for a phenomenology of climbing, it is argued that what Heidegger calls readiness to hand presupposes readiness-to-foot (Zufussenheit). The latter gives ground for gratitude not only because it gives ground for enjoyment as gratification, but because it also gives ground for joy understood as a grace, grace understood as having its ground in Natura.
