This article by Clive Hamilton, I think, marks what is at stake in the New Materialisms and some of the Speculative Realisms.  The issue is not some hackneyed attempt to champion the sciences and objectivity over meaning, but to draw attention to the material dimensions of how we dwell and live.  Today, more than ever, we need to reflect on whether the tools of deconstruction, phenomenology, psychoanalysis, Marxist critical theory, and semiotics are adequate to thinking the world we dwell in and how these theoretical orientations might erase the fundamental materiality of existence.  This erasure is so thorough that it’s difficult to even discern when working within these theoretical frames for, after all, one can only see what one can see, and being is here reduced to meaning.  This critical reflection is not undertaken to erase these methodologies– quite the contrary –but to mark their limits, note their blindspots, and develop a theoretical frame capable of both preserving what is vital in these forms of thought and of moving beyond those limitations.  This is what is at stake in the critique of correlationism.  Materiality is not phenomenality, a lived experience, a meaning, nor a text– though it can affect all of these things –but something with its own dynamics and forms of power.  We need a form of theory capable of thinking that and that avoids the urge to treat everything as texts, meanings, and correlates of intentions.
