In a 1957 essay, "Hebel - Friend of the House," ("Hebel der Hausfreund") Heidegger underscores his great concern with the impoverishment of poetic language via commonplace 'calculative, instrumental' use. He discusses the importance of German poet/writer Johann Peter Hebel (1760-1826) who, he feels, embodied an authentic poetic relationship with language as personified in fellow-poet Friedrich Hölderlin's dictum "poetically... (we) dwell upon the earth."
