This essay approaches Derrida through a consideration of his writings on Saussure and Husserl. Derrida is right to insist, following Saussure, on a relational theory of meaning: words do not have a one-to-one correspondence with their referents. But he is wrong to insist on a purely differential theory of meaning: words can refer to reality within the context of a body of knowledge. Similarly, Derrida is right to reject Husserl's idea of presence: no truths are simply given to consciousness. But (...) he is wrong to reject the very idea of objective knowledge: we can defend a notion of objective knowledge couched in terms of a comparison of rival bodies of theories. The essay concludes by considering the implications of the preceding arguments for the enterprise of phenomenology. (shrink)
