"The writerly text is a perpetual present, upon which no consequent language (which would inevitably make it past) can be superimposed; the writerly text is ourselves writing, before the infinite play of the world (the world as function) is traversed, intersected, stopped, plasticized by some singular system (Ideology, Genus, Criticism) which reduces the plurality of entrances, the opening of networks, the infinity of languages."

"The word 'differance', spelled with an 'a', is a coined term, and Derrida contrasts it with the vernacular term 'difference'. Patterns of 'Difference,' he explains, [are ] ...'produced' - deferred -- by 'differance' (Derrida, 1982, p.14). But what does this mean? That difference is deferred by differance? Imagine observing a quilt on the wall with patches of yellow, blue and white. If you notice the yellow and the non-yellow, you see a pattern of concentric boxes. If you notice the blue and the non-blue you see a chequered design. Each pattern is a play of differences, but it is a different set of differences when yellow is differentiated from non-yellow than when blue is differentiated from non-blue, a different set of differences that shows us different patterns. What is interesting about this shift from one pattern to the other is that it not only calls our attention to a new pattern, but that it suppresses our awareness of the other pattern. DifferAnce, defers a pattern of differences (say the pattern of differences between the blue and the not-blue). That is, one pattern of differences pushes into the background another possible play of patterns. You cannot study the pattern of yellows and the pattern of blues at the same time because differance causes one or the other patterns to be 'deferred'. DifferAnce is the hidden way of seeing things that is deferred out of awareness by our distraction with the imagery that captures our attention. Because it contains this other way to see things 'DifferAnce is the...formation of form.'(Derrida, 1976, p.63)."
