"Intertextuality and the Discourse Community"

In “Intertextuality and the Discourse Community,” Porter defines intertexuality by saying that writing has bits and pieces of other writings that make it up. This means that when an article writes a piece, that piece is essentially made from putting together parts of numerous other writings. If what Porter says is true, then he is overriding what was mentioned at the beginning which was that writings should be original and autonomous. Porter’s ideas challenge Murray’s idea that all writing is autobiographical because it puts the emphasis on deriving the piece from multiple other sources/pieces where as Murray makes his claim that writing is autobiographical and  our writings are reflections of our own beliefs, thoughts, and feelings. Personally I think that both authors make valid arguments and that writings can come from both personal beliefs/ experiences as well as other writings that the author has read.
