Derrida: “There is nothing outside of the text” (Of Grammatology, 158).
I’m not particularly fond of Derrida, though I have found some useful things within his ideas.
This is an interesting idea, particularly when the definition of text can be expanded exponentially–to an image, a nonverbal communication, a clothing outfit.
If there is nothing outside of the text, literally, then everything we see, hear, smell, taste, touch, and think about is text. That seems a little too inclusive, even for those of us who are interested in expanding rhetoric out of speech and composition and into visual culture, among other things.
