Rendering Heidegger's translation of Parmenides' ἀτρεμἐϛ, being "unshaken," Joan Stambaugh gives us "untrembling."¹ Anglophone readers used to other translations and reading Parmenides' description of "well-rounded truth" as "unshaken" are inclined to prefer customary versions to Stambaugh's "untrembling"—such is the force of habit that haunts first encounters with an author in translation, a habit in this case that crosses two linguistic spheres, not only German but also Greek, owing to the omnipresence of Kirk, Raven, and Schofield,² where their unshaken (sometimes unmovable) follows the already classic tradition of Diels-Kranz' own "unerschütterlich."
