"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
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)."
