Derrida's deconstructive style of reading subverts these assumptions and challenges the idea that a text has an unchanging , unified meaning. Western culture has tended to assume that speech is a clear and direct way to communicate. Drawing on psychoanalysis and linguistics, Derrida questions this assumption. As a result, the author's intentions in speaking cannot be unconditionally accepted. T his multiplies the number of legitimate interpretations of a text.
Deconstruction shows the multiple layers of meaning at work in language.
By deconstructing the works of previous scholars, Derrida attempts to show that language is constantly shifting. Although Derrida's thought is sometimes portrayed by critics as destr uctive of philosophy, deconstruction can be better understood as showing the unavoidable tensions between the ideals of clarity and coherence that govern philosophy and the inevitable shortcomings that accompany its production.
