how can we even give it a name? Whatever withdraws, refuses arrival. But—withdrawing is not nothing. Withdrawal is an event. In fact, what withdraws may even concern and claim man more essentially than anything present that strikes and touches him. Being stuck by actuality is what we like to regard as constituitive of the actuality of the actual. However, in being struck by what is actual, man may be debarred precisely from what concerns and touches him--touches him in the surely mysterious way of escaping him by its withdrawal. The event of withdrawal could be what is most present in all our present, and so infinitely exceed the actuality of everything actual.

What withdraws from us, draws us along by its very withdrawal, whether or not we become aware of it immediately, or at all. Once we are drawn into the withdrawal, we are drawing towards what draws us, our essential nature already bears the stamp of "drawing toward." As we are drawing toward what withdraws, we ourselves are pointers pointing toward it. We are who we are by pointing in that direction--not like an incidental adjunct but as follows: this "drawing toward" is in itself an essential and therefore constant pointing toward what withdraws. To say "drawing toward" is to say "pointing toward what withdraws."

To the extent that man is drawing that way, he points toward what withdraws. As he is pointing that way, man is the pointer. Man here is not first of all man, and then also occasionally someone who points. No: drawn into what withdraws, drawing toward it and thus pointing into the withdrawal, man first is man. His essential nature lies in being such a pointer. Something which in itself, by its essential nature, is pointing, we call a sign. As he draws toward what withdraws, man is a sign. But since this sign points toward what draws away, it points, not so much at
