In this article I will suggest ways in which adding the French philosopher Gilles Deleuze to the mix can complement and extend the 4EA approach to cognitive science. In the first part of the paper, I will show how the Deleuzean tripartite ontological difference (virtual/intensive/actual) can provide an explicit ontology for dynamical systems theory. The second part will take these ontological notions and apply them to three areas of concern to the 4EA approaches: (a) the Deleuzean concept of the virtual (...) will clarify the ontological status of perceptual capacity as sensorimotor skill; (b) the Deleuzean concept of “intensive individuation” will clarify the ontological status of the genesis of perceptually guided behavior; (c) the Deleuzean critique of confusing the actual and the virtual will enable us to intervene in the realism/idealism debate. These aspects will not be addressed sequentially but will be interwoven into an unfolding argument. (shrink)

This article charts differences between Gilles Deleuze's and Gaston Bachelard's philosophies of science in order to reflect on different readings of the role of science in Deleuze's philosophy, in particular in relation to Manuel DeLanda's interpretation of Deleuze's work. The questions considered are: Why do Gilles Deleuze and Gaston Bachelard develop radically different philosophical dialectics in relation to science? What is the significance of this difference for current approaches to Deleuze and science, most notably as developed by Manuel DeLanda? It (...) is argued that, despite its great explanatory power, DeLanda's association of Deleuze with a particular set of contemporary scientific theories does not allow for the ontological openness and for the metaphysical sources of Deleuze's work. The argument turns on whether terms such as ‘intensity’ can be given predominantly scientific definitions or whether metaphysical definitions are more consistent with a sceptical relation of philosophy to contemporary science.
