Postmodernists used Jacques Derrida's statement 'There is no outside to the text' to destroy other people's work but Derrida wasn't part of Team Postmodernism, he was a philosopher. It is said of Derrida that he was the only modern mind to understand the importance of the apophatic way of Pseudo Dionysius the Areopagite for deconstruction.
He said that mystics were involved in a necessary self-deception.
Theologians and mystics will insist that God is unknowable and then write volumes about the nature of God.
There is no outside to the text - Jacques Derrida
The statement, which occurs in his book Grammatology, can only be true inside that text.
He is involved in a necessary self-deception.
