In An Introduction to Metaphysics Heidegger asserted that “it wasnot German idealism that collapsed; rather, the age was no longer strong enough to sustain the greatness, breadth, and originality of that spiritual world, i.e., truly to realize it” (1961, p. 37). He was at this point launchinginto one of the major themes of his later work: the “darkening of the world” in the form of the materialism and “demonism” typified by the antitheses of the USSR and the USA, a polarity of seeming opposites obscuring an underlying fundamental similarity. This was the modernist faith of both cultures in the power of science to solve all of the problems that have plagued humanity for untold centuries, a faith in the power of science to tell us the absolute truth about the nature of reality. In 1955 Heidegger also characterized science and technology in “The Question Concerning Technology” as an “enframing” (Gestell), a particular dominant interpretation of reality dependent on the interest of control and which conceals far more than it reveals. For one thing, “the essence of technology isin a lofty sense ambiguous. Such ambiguity points to the mystery of all revealing, i.e., of truth” (1977a, p. 33). Although enframing “lets man endure,” only art (poiesis) as the successor of philosophy transcends techne by allowing us to see that “the essence of technologyis nothing technological” (1977a, p. 35). Much earlier, in Being and Time, he gave his first sustained account of science as the interpretationof reality driven by technological interests, and spoke of Being as the “transcendens” lying beyond “every possible character which an entity can possess” [p. 38]. It remains debatable whether this characterization of Being survived into Heidegger's later period, but despite his nostalgia for the spirituality of the early nineteenth century, the role of Beingin these earlier works might best be explained as some kind of realism.
