Jacques Derrida said this quote

But because me and myself, as you no doubt are well aware, we are going to die, my relation—and yours too—to the event of this text, which otherwise never quite makes it, our relation is that of a structurally posthumous necessity.Suppose, in that case, that I am not alone in my claim to know the idiomatic code (whose notion itself is already contradictory) of this event. What if somewhere, here or there, there are shares in this non-secret’s secret? Even so the scene would not be changed. The accomplices, as you are once again well aware, are also bound to die.

~ Jacques Derrida

And still the text will remain, if it is really cryptic and parodying (and I tell you that it is so through and through. I might as well tell you since it won’t be of any help to you. Even my admission can very well be a lie because there is dissimulation only if one tells the truth, only if one tells that one is telling the truth), still the text will remain indefinitely open, cryptic and parodying.

~ Jacques Derrida

A text is not a text unless it hides from the first comer, from the first glance, the law of its composition and the rules of its game. A text remains, moreover, forever imperceptible. Its laws and rules are not, however, harbored in the inaccessibility of a secret; it is simply that they can never be booked, in the present, into anything that could rigorously be called a perception.

~ Jacques Derrida

Every sign, linguistic or nonlinguistic, spoken or written (in the usual sense of this opposition), as a small or large unity, can be cited, put between quotation marks; thereby it can break with every given context, and engender infinitely new contexts in an absolutely nonsaturable fashion. This does not suppose that the mark is valid outside its context, but on the contrary that there are only contexts without any center of absolute anchoring. This citationality, duplication, or duplicity, this iterability of the mark is not an accident or anomaly, but is that (normal/abnormal) without which a mark could no longer even have a so-called “normal” functioning. What would a mark be that one could not cite? And whose origin could not be lost on the way?
