A promise, in Derrida’s account, is not a statement about what already is. It is a mark that binds a future that has not yet arrived. The force of the promise depends on its iterability. It must be able to be cited later, in the absence of the one who made it. A promise that could not survive its first utterance would not bind anyone who was not present at the moment it was spoken.

The public tape is a system of such marks. Title, mint, lien, and conversion are promises that have entered a shared spacing. They can be opened after the office that wrote them has moved on. The Third Seat’s refusal is one such promise. The no binds a future reading. Later readers encounter it as part of the sequence. It has not expired.

The quiet print claims the force of a promise without having entered the system that would make it citable. It is treated as already binding on the future. It cannot be detached and re-read. The speculative chart performs the same claim with the end. It offers a final promise that the unfinished middle has been closed. The promise has not entered the tape. The public book refuses both. A mark that has not become iterable does not yet bind the future the others will still read.

Iterability. The mark must be able to function after its first writing. A private announcement does not meet the condition.

Public citability. Later readers must be able to open the line and place it inside the sequence that still continues.

No private close. A promise that claims to finish the future without having entered the tape has not yet bound it.
