Derrida states that his use of the word deconstruction first took place in a context in which "structuralism was dominant" and its use is related to this context. Derrida states that deconstruction is an "antistructuralist gesture" because "Structures were to be undone, decomposed, desedimented." At the same time for Derrida deconstruction is also a "structuralist gesture" because it is concerned with the structure of texts. Post-structuralism is a movement after structuralism, how does deconstruction differ from it?
