This book gets five stars from me...but this review (which I initially made as a comment to another review), is in response to the Derrida/Searle debate, and the Searle quote that is so often cited as the wooden stake to Derrida's deconstructive heart. Here we go...
Searle willfully misreads Derrida, or at the very least, doesn't take the time to understand his theory properly. The supposed limitation of deconstruction, the idea "that deconstruction deconstructs itself," is a "limitation" that Derrida was certainly aware of, and in fact, is not a limitation at all. Deconstruction must deconstruct itself. If it did not, it could not be articulated or exist in language. If deconstruction was not privy to the very process it describes, it would itself become the very sort of notion that it condemns and says is impossible, the idea of something "absolutely present outside of a system of differences." Every word/concept capable of being articulated and understood in language can only be understood in a system of differences. This means, essentially, that a word never has a positive meaning derived from itself, but rather, we can only understand the meaning of a word by the way in which it differs from other words. We must essentially rule out everything it is not (to the extent which are finite language system allows) in order to articulate what it "is." The idea of deconstruction is essentially an expansion of this concept. For example, good is privileged over evil, however, good can only be truly understood in the context of evil, by the way in which it differs from evil. If there was no evil, there could be no good, or at least "good" in a sense that we can understand because it would have nothing to compare itself to. It must exist in a system of differences--good "differing and deferred" from evil. In this same way, deconstruction must be dependent on the very thing it critiques in order to exist at all. It's paradoxical thinking, but it has to be. Deconstruction needs logocentrism to exist, and vice versa. The flaw is not in deconstruction, but in our language, and our radical distinction between true and false. Our society privileges truth over falsity (and rightly so), and so, in order for deconstruction to be believed in, it must be said to be true, which immediately makes it privileged, which in turn makes it false, because there can be no privileging. This is not due to the invalidity of deconstruction, but rather to our inherent privileging of truth. Deconstruction itself is neither true nor false, presence nor absence, "but exceeds them both." If deconstruction did not deconstruct itself, it would become something "absolutely present outside a system of differences," the very sort of thing Derrida condemns as being dependent on a sort of creationist theology, something absolutely present outside the system, whose meaning and existence is self-contained and self-referential, only coming from itself. Furthermore, privileging is more complicated than a willful act on our parts, but again, also comes from flaws within the system of language itself. In the beginning of this review, I cited the Derrida/Searle debate. Here, I have already privileged Derrida by placing him first. I suppose I could have written, Derrida/Searle, Searle/Derrida, but even then, I'm still privileging; the set of terms where Derrida is privileged because it comes before the set of terms in which Searle is privileged. The same would happen if I wrote Searle/Derrida, Derrida/Searle. Because we read left to right, there is no way out of this. We have the same problem writing Mr. and Mrs. on an envelope, we can either write Mr. and Mrs. Smith, in that order, or Mrs. and Mr. Smith, if we want to be avoid traditional gender hierarchies, but either way, because we read left to right, we inherently have to make a choice which we privilege something, one over the other--we cannot read/view them simultaneously, in one fell swoop in a way that would privilege neither. Again, the flaw is not in deconstruction, but in the language system and the reading structure itself.
As for the claims against Derrida's writing, I personally "like" it, but I won't defend it. He is willfully obscure (although not entirely without a purpose), but that doesn't undermine the validity or importance of what he's saying. To a degree, it was necessary for his writing, at least regarding deconstruction, to be thorough, "repetitive," and obscure, otherwise, people's understanding of it would be too simplistic and reductive. In fact, this tendency to reduce deconstruction to a formula (which is so prevalent among the majority of literary criticism that cites Derrida), is the every sort of thing Derrida was trying to avoid. Again, his writing is frustrating, but it is completely understandable if you're willing to either read very slowly, or go through one or two re-readings. Whether you want to go through that work is another question, but that does diminish the worth of what he has to say.
And as a final note, just so you know, I'm not one of those people who enjoys obscurity for the sake of obscurity or to make myself feel intelligent, I find some of the other french writers to be completely full of hot air, using opacity to cover up either faulty scholarship or to boost their egos (Lacan and Kristeva come to mind). I will also add that I can't stand most people's (ab)use of Derrida, I think he ranks up there with Freud in terms of willful misapplication (although, if I'm being honest, I'm not much of a Freudian). I understand people's hostility to Derrida, on Searle's part, I think it was a bit of jealousy regarding Derrida's "rock-star" status in academia, and for others, I think it stems from the ways in which they see Derrida being misused. I only advise you to read him with an open mind and then decide from there. If you're intelligent (and since you're attempting to read of Grammatology, you most likely are) then you are probably used to understanding things immediately. However, if you are going to get anything out of Of Grammatology, then you need to humble yourself a bit, slow yourself down, and be willing to accept that you might not get it right away. I assure you, if you're patient and are willing to look up a bit of terminology, you'll eventually get what he's saying.
And one last last thing...I really recommend reading his essays "Differance," and "Structure Sign and Play in the Discourse of the Human Sciences" before you tackle this one. They clarify some key concepts that you need to understand Of Grammatology. "Force and Signification" is also useful.
