Gatsby Won't Deconstruct Itself

So far Lois Tyson has written on each of the criticisms we have studied in a manner that at least appears cohesive and with a purpose. I am still not clear as to if it is simply the nature of deconstructive criticism or if the actual text of Gatsby does not lend itself to deconstructive theory, but the arguments she puts together seem to be a stretch. Not to deconstruct the textbook, but in the very conclusion Tyson contradicts her hypothesis that "this ideological project is undermined by the inseparability in the text itself of past and present, innocence and decadence, and West and East." (278) when she says that a "deconstructive readon of The Great Gatsby surely will not eliminate an emotional investment..."(278). If the deconstruction of the book cannot void the emotional polarity of past and present, West and East in American culture, how can it truly have deconstructed the book? Any theme that runs so deep through a book as the theme of time will have an emotional impact upon the reader. In fact, if the theme in question does not make the reader feel something then how can the theme really convey any message if not expressly stated.
