Matter and Sense in Gilles Deleuze’sLogic of Sense: Against the ‘Ism’ in Speculative Realism

Abstract

I argue against the use of general ‘ism’ terms such as ‘speculative realism’ and ‘correlationism’ by Harman. This use is contrasted with more nuanced readings of philosophers, referring to Bryant and DeLanda’s more subtle versions of materialism that do not fit the general label. Instead of general categories I defend Deleuze’s use of the concept of problem as studied by Bell. This argument is then developed through a close reading of Logic of Sense, against Harman’s denial of the reality of relations and processes. I demonstrate that Deleuze is not a correlationist as defined by Harman, by following Sauvagnargues, Smith and Beistegui on the concepts of event and simulacrum in Logic of Sense. I then consider Deleuze’s study of language and his argument that designation, signification and manifestation rely on the concept of sense. This argument leads to a position which is neither idealism, nor materialism, because the differential processes at work in sense cannot be reduced to matter or to the subject, working instead between them and denying their independent reality.
