This paper aims to elucidate at least a part, if not all, of the reasons why Heidegger started to incline to poeticizing (Dichtung) when, in 1930s, he tried to reformulate and radicalize his metaphysical thinking (Denken) toward "being" (Sein) as it is. The lecture in 1935 entitled "An Introduction to Metaphysics", along the line of whose discussion we will compose our following argument, deals almost exclusively with the traditionally long-prevailing metaphysical question, "Why are there essents rather than nothing?", but what interests us in the first place is that, in the course of the lecture, he regarded it as inevitable to attend to Nietzsche's defying words, that is, "being" as "a vaguely remaining mist of evaporating reality".
Going through such a devastating charge against traditional metaphysics and its terms, Heidegger made his narrow way out to the significance of language for the metaphysical thinking. Although, in this lecture, he didn't seem to have a strong intention of pushing this reconfirmed problem of language through to its end, we have a good reason to assume that, especially when he presented a concept of "being" as "Vielfalt", which means literally "multi-plication", he was at the same time considering a poeticizing language of vital importance for the enduring quest for a whereabouts of "being"as it is.
