  Heidegger argues that if humankind is to enter into safeguarding, it needs to learn (or perhaps to learn once more) to think of Being as a gift that has been granted to us in history. Indeed, to think properly is precisely to be grateful for the gift of Being (see What is Called Thinking?). (Terms such as ‘gift’ and ‘granted’ should not be heard theologically, but in terms of secularized sacredness and destining.) In this learning process, certain artworks constitute ontological beacons that disrupt the technological clearing. Thus recall that Heidegger identifies a shared form of disclosure that is instantiated both by the old wooden bridge over the Rhine and by Hölderlin's poem “The Rhine”. We can now understand this identification in terms of the claim that certain artworks (although of course not those that themselves fall prey to technological thinking) share with traditional artisanship the capacity to realize poiesis. In so doing such artworks succeed in bringing us into contact with the mystery through their expression of dwelling (poetic habitation). In listening attentively and gratefully to how Being announces itself in such artworks, humankind will prepare themselves for the task of safeguarding.
