Jaques Derrida, Differance at the Orgin Kamuf, Peggy A. A Derrida Reader: Between the Blinds NY Columbia A.P., 1991 (p 62)
"In attempting to put into question these traits
of the provisional secondariness of the substitute one would come to see
something like an originary differance; but one could know longer call
it originary or final in the extent to which the values of origin, archie-telos,
escaton, etc. have always denoted presence- ousia, parousia. To put into
question the secondary and provisional characteristics of the sign, to
oppose to the man "originary" differance, therefore would have
to consequences.
1. One could no longer include differance in the concept of the
sign, which always has meant the representation of a presence and has been
constituted in a system (thought or language) governed by and moving toward
presence.
2. And thereby one puts onto question the authority of presence or of its
simple symmetrical opposite, absence, or lack. Thus, open questions the
limit that has always constrained us. Still constrains us- as inhabitants
of a language and a system of thought- to formulate the meaning of Being
in general as presence or absence, in the categories of being or being-ness
(ousia)."
