If we now consider that being conceals itself, indeed that self-concealment belongs to being’s essence, it might seem once again as if being remains completely and necessarily withdrawn from us. But again, it can only seem so. For we lay claim to being everywhere, wherever and whenever we experience beings, deal with them and interrogate them, or merely leave them alone. We need being because we need it in all relations to beings. In this constant and multiple use, being is in a certain way expended.
And yet we cannot say that being is used up in this expenditure. Being remains constantly available to us. Would we wish to maintain, however, that this use of being, which we constantly rely upon, leaves being so untouched? Is not being at least consumed in use? Does not the indifference of the “is,” which occurs in all saying, attest to the wornness of what we thus name?
Being is certainly not grasped, but it is nevertheless worn-out and thus also “empty” and “common.” Being is the most worn-out.
“Being” stands everywhere and at each moment in our understanding as what is most self-understood. It is thus the most worn-out coin with which we constantly pay for every relation to beings, without which pay no relation to beings as beings would be allotted us. Being, the most worn-out and the most indifferent! And yet: we do not throw the “is” away; we also never become weary of the being of beings. Even where one might sometimes wish, oneself, no longer to be, ennui pertains only to oneself as this existing human being, but not to being. Even in that most extreme satiety that secretly remains a wishing, and wishes there might be the Nothing instead of beings, even there being remains the only thing called upon that resists expenditure and consumption. For also where we expect that it would be preferable for the Nothing to be, the last saving grasp is aimed at the most worn-out—at being. Therefore being can never become worn-out to the point of complete exhaustion and disparagement. On the contrary, in the extremity of the desired annihilation of all beings, and precisely here, being must appear. It appears here as something unprecedented and untouched, from out of which stem all beings and even their possible annihilation. Being first lets every being be as such, that means to spring loose and away, to be a being, and as such to be “itself.” Being lets every being as such originate. Being is the origin.
