This discourse became accepted as the dominant explanation, and its assumptions began to seep into the discourse of the everyday. In this way the human subjects's experience of their own sexuality is shaped and controlled by the discourses that purport to explain it. Foucault does not offer any all-embracing theory of human nature. For Foucault there is no ultimate answer waiting to be uncovered. The 'discursive practices' of knowledge are not independent of the objects that are studied, and must be understood in their social and political context.
Text structures our interpretation of the world.
Derrida thought that all text contained a legacy of these assumptions, and as a result of this, these texts could be re-interpreted with an awareness of the hierarchies implicit in language. Derrida does not think that we can reach an end point of interpretation, a truth. Meaning is diffuse, not settled. Textuality always gives us a surplus of possibilities, yet we cannot stand outside of textuality in an attempt to find objectivity. One consequence of deconstruction is that certainty in textual analyses becomes impossible.
