Deconstruction denotes the pursuing of the meaning of a text to the point of exposing the supposed contradictions and internal oppositions upon which it is founded—supposedly showing that those foundations are irreducibly complex, unstable, or impossible. It is an approach that may be deployed in philosophy, in literary analysis, and even in the analysis of scientific writings. Deconstruction generally tries to demonstrate that any text is not a discrete whole but contains several irreconcilable and contradictory meanings; that any text therefore has more than one interpretation; that the text itself links these interpretations inextricably; that the incompatibility of these interpretations is irreducible; and thus that an interpretative reading cannot go beyond a certain point. Derrida refers to this point as an "aporia" in the text; thus, deconstructive reading is termed "aporetic." He insists that meaning is made possible by the relations of a word to other words within the network of structures that language is.
