It should not be unheeded that it is the difference which usually determines affirmative phrases where difference is counterbalanced in their intermediacy: but in the language only differences devoid of affirmative phrases exist. In the language, considering sign or signified, no concept or vocal could be found which had existed prior to the language, in lieu, only vocal or conceptual differences, engendered by the grammatological scheme, could be descried. The concept or the essence which the sign enfolds carries less significance than other signs which are encompassing it. The mere proof of this claim is that by changing its adjacent words, the value of a term could be altered and this is achieved without implementing a change in its own meaning or voice. What is of import in the post-structural critic of philosophers effected by de Saussure is his debased organization of though and not a sign-based one regarding the narrative of construction.
