Deconstruction emphasizes the lack of totality and closure in any form.
The line tends to become encrusted with its preconditions and with meta-comments and amplifications. Imagine a text that became nothing but footnotes and marginalia referring to one another. This text would say many things at once without granting primacy to any of them. As Kolb and others have noted, Derrida has become a potent influence for those exploring various theories of hypertextual writing. I don't want to necessarily debunk such notions, but I do want to explain how Derrida has influenced my own thinking about the differences between writing hypertextually and writing in linear form.
