[...] Abraham's gesture, of raising the eyes, though a formulaic one in biblical narrative, takes on here a great power of dread, as if Abraham can hardly bear to look upon the chosen site. Kierkegaard's inspired, appalled rewriting of this scene in Fear and Trembling emphasises its unspeakability. The tragic hero, he says, renounces himself in favour of expressing the universal. He gives up what is certain for what is more certain; he gives up the finite to attain the infinite; and so he can speak publicly about it, he can weep and orate, secure that at least someone will understand his action. But Abraham 'gives up the universal in order to grasp something still higher that is not the universal', because what he is obeying, what he is grasping for, is barbarously incomprehensible. So Abraham is utterly alone and cannot speak to anyone of what he is about to do, because no one would understand him.
