Maybe we all need to read up on post-structuralism; from: http://en.wikipedia.org/wiki/Post-structuralism
"Post-structural practices generally operate on some basic assumptions;
* Post-structuralists hold that the concept of "self" as a separate, singular, and coherent entity is a fictional construct. Instead, an individual comprises tensions between conflicting knowledge claims (e.g. gender, race, class, profession, etc.). Therefore, to properly study a text a reader must understand how the work is related to his or her own personal concept of self. This self-perception plays a critical role in one's interpretation of meaning. While different thinkers' views on the self (or the subject) vary, it is often said to be constituted by discourse(s). Lacan's account includes a psychoanalytic dimension, while Derrida stresses the effects of power on the self. This is thought to be a component of post-modernist theory.
* The author's intended meaning, such as it is (for the author's identity as a stable "self" with a single, discernible "intent" is also a fictional construct), is secondary to the meaning that the reader perceives. Post-structuralism rejects the idea of a literary text having a single purpose, a single meaning, or one singular existence. Instead, every individual reader creates a new and individual purpose, meaning, and existence for a given text. To step outside of literary theory, this position is generalizable to any situation where a subject perceives a sign. Meaning (or the signified, in Saussure's scheme, which is as heavily presumed upon in post-structuralism as in structuralism) is constructed by an individual from a signifier. This is why the signified is said to 'slide' under the signifier, and explains the talk about the "primacy of the signifier."
* A post-structuralist critic must be able to use a variety of perspectives to create a multifaceted interpretation of a text, even if these interpretations conflict with one another. It is particularly important to analyze how the meanings of a text shift in relation to certain variables, usually involving the identity of the reader."
-what the author meant is less important than what what the reader thinks it means
-the above will be very individual
-texts mean different things at the same time
