From Peirce, a sign represents something other than itself, an object, for some third; from Deleuze, a sign can create and erase an object, for some third. He makes this claim in the cinema books, without detailed explication. It is a fleeting reference to the Peircean triad developed in his semiotics; moreover, references to “objects” in Deleuze’s discussions of signs in his other work are often generic. In this essay, I explain what it means in Deleuze’s semiotics for a sign (...) to create and erase its object. My method is to use the perspective of the object in the semiotic triad to compare Deleuze and Peirce’s semiotics. Deleuze’s sign that creates and erases its object marks a clear departure from Peirce’s semiotics. For Deleuze, like Peirce, an acquaintance with the object independent of the action of the sign is necessary for semiotics. Of most significance is that for Peirce, thinking with signs necessarily involves modifying prior knowledge of the object – meaning one’s conception of the object is a version of what was already known; while for Deleuze, thinking with signs can involve producing ideas at a second remove from the object – in turn, creating and erasing new object(s). Ultimately, this essay contributes to research on Deleuze’s cinema books by undertaking a detailed reading of a part of his discussion that has not been analyzed. Furthermore, in producing Deleuze’s concept of a sign that creates and erases its object, this essay reminds us how we think – andcouldthink – with signs, reaffirming the importance of semiotic analysis for discussion about thinking with signs. Finally, this essay contributes to scholarship on Deleuze’s and Peirce’s semiotics. (shrink)
