Speech and Phenomena
Derrida's first book length deconstruction is his critical engagement with Husserl's phenomenology in Speech and Phenomena published in 1967. Derrida states that Speech and Phenomena is the "essay I value the most" and it is therefore a very important example of deconstruction. Husserl's philosophy is grounded in conscious experience as the ultimate origin of validity for all philosophy and science. Derrida's deconstruction operates by illustrating how the originary status of consciousness is compromised by the operation of structures within conscious experience that prevent it from being "the original self-giving evidence, the present or presence of sense to a full and primordial intuition." Derrida argues that Husserl's "phenomenology seems to us tormented, if not contested from within, by its own descriptions of the movement of temporalization and language". Derrida argues that the involvement of language and temporalisation within the "living present" of conscious experience means that instead of consciousness being the pure unitary origin of validity that Husserl wishes it be, it is compromised by the operation of différance in the structures of language and temporalisation. Derrida argues that language is a structured system of signs and that the meaning of individual signs is produced by the différance between that sign and other signs. This means that words are not self sufficiently meaningful but only meaningful as part of a larger a structure that makes meaning possible. Derrida therefore argues that the meaning of language is dependent on the larger structures of language and cannot originate in the unity of conscious experience. Derrida therefore argues that linguistic meaning does not originate in the intentional meaning of the speaking subject. This conclusion is very important for deconstruction and explains the importance of Speech and Phenomena for Derrida. Informed by this conclusion the deconstruction of a text will typically demonstrate the inability of the author to achieve their stated intentions within a text by demonstrating how the meaning of the language they use is, at least partially, beyond the ability of their intentions to control. Similarly, Derrida argues that Husserl's description of temporal of consciousness - where he describes the retension of past conscious experience and protension of future conscious experience - introduces the structural différance of temporal deferral, temporal non-presence, into consciousness. This means that the past and future are not in the living present of conscious experience but they taint the presence of the living present with their conscious absence through retension and protension. Husserl's description of temporal consciousness therefore compromises the total self presence of conscious experience required by Husserl's philosophy once again.
