"Derrida has been assuming all along that the linguistic processes described by Saussure, signification and the differencing of signs, act like forces. If so, then there is no reason for them to stop, and each sign evoked by difference will introduce a new set of differences. But there is no justification for making Saussure's signifiers and differences into forces, and indeed, there is no longer any justification for Saussure's signifiers and differences. Justification or no, language for Derrida lacks the stability that Saussure found. Saussure's neat pairings of signifier and signified came from a finite system of distinctive features. By contrast, Derrida's signifier and signified go on and on in endless differencing or differing or deferring (all terms involved in Derrida's own word, différance). And since our minds only work in signs, and nothing is ever fully present in signs, everything becomes flickering and unstable, both present and absent, present and future. It follows therefore that human beings are not the master of language, since the forces of language cannot be mastered. I try to mean, but my meaning is dispersed, divided, at odds with itself. Indeed, I myself am one of my meanings, as much a fiction, as little a stable entity as they. In Terry Eagleton's phrasing, "Because language is the very air I breathe, I can never have a pure, unblemished meaning or experience at all." Wow! With one masterful stroke, Derrida seems to have gotten rid of meaning, structures, categories, and mankind itself. Yet the whole argument rests on the idea of signification. As Eagleton sums the position up, "If the theory of signification . . . is at all valid, then there is something in writing itself which finally evades all systems and logics." But that's the trouble. It is not valid. Saussure's is finally a flat earth theory. If we consider only how the hearing and the understanding of a word feel to us, if we only introspect, his account has a certain commonsensical appeal. It seems right, just as the horizon seems to define a flat earth. A better linguistics, though, and a great deal of psychological evidence show that Saussure's theory leaves out a world of complexities. The text-active model leaves out all of human activity in interpreting language or the world. So does Derrida."
