Deconstruction is an approach, introduced by French philosopher Jacques Derrida, which rigorously pursues the meaning of a text to the point of exposing the contradictions and internal oppositions upon which it is apparently founded and showing that those foundations are irreducibly complex, unstable, or impossible. It is an approach that may be deployed in philosophy, literary analysis, or other fields.
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, and terms deconstructive reading "aporetic." J. Hillis Miller has described deconstruction this way: “Deconstruction is not a dismantling of the structure of a text, but a demonstration that it has already dismantled itself. Its apparently-solid ground is no rock, but thin air."
