As befits a French philosopher of the 1960s, Gilles Deleuze (1925-995), was famous for his antihumanism and his anti-essentialism. Humans are fully part of nature with no supernatural supplement; and essences are not the way to individuate things. That doesn’t seem to leave much room for a Deleuzean human nature, but that’s what I want to try to explore. I’ll take my clue from what he says in A Thousand Plateaus about nomads, who “reterritorialize on their power of deterritorialization.” In other words, they are most at home when on the move. But this isn’t just spatial movement; we can also say that the habit of nomads is to break habits. I’ll make sense of this claim by referring to Bruce Wexler’s Brain and Culture (MIT, 2006), in particular, his claim that humans evolved for a lengthy childhood period of socially mediated neuroplasticity. Human nature on this view is such that we are individuated by our singular patterns of social – somatic interaction. And this in turn is “nomadic” in Deleuze’s sense: our nature is to be so open to our nurture that it becomes second nature. That is, we’re at home wherever home is. There’s an anti-essentialist nuance here, however. It’s children who are most “nomadic,” most plastic. Most adults drift away from nomadism and become sedentary: they want more of the same. But even here we must nuance things: what if “more of the same” means “more change”? In other words, are there adult “nomads”? I think there are. But we’ll need to discuss Deleuze’s ontology first in order to make sense of these claims. Deleuze is an interactive process philosopher: we aren't substances but processes and those processes are not individuated by properties but as singular patterns of social and somatic interaction. The embodied and the embedded aspects of our being intersect – we are bodies whose capacities form in social interaction. And it's in this intersection of the social and the somatic that subjectivity and selfhood emerge – and are sometimes attenuated and even bypassed..

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

Once one of the most important philosophical concepts (it is impossible to think of Plato without erôs, or Aristotle without philia, or Augustine without caritas and cupiditas), love doesn't get much philosophical notice nowadays, at least outside psychoanalytic circles. Or so it seems. But couldn't one just as well say that Derrida and Deleuze think about nothing but love? What have they written that isn't linked rather directly to desire, to alterity, to getting outside oneself, even if "love" isn't among their..

OVERVIEW. The concept of emergence – which I define as the (diachronic) construction of functional structures in complex systems that achieve a (synchronic) focus of systematic behaviour as they constrain the behaviour of individual components – plays a crucial role in debates in philosophical reflection on science as a whole (the question of reductionism) as well as in the fields of biology (the status of the organism), social science (the practical subject), and cognitive science (the cognitive subject).1 In this essay I examine how the philosophy of Deleuze and that of Deleuze and Guattari2 can help us see some of the most important implications of the debate on the status of the organism, as well as prepare the ground for a discussion of the practical and cognitive subject.

DEFINING THE LIMITS OF THE FIELD. Because 'consciousness and the body' is central to so many philosophical endeavors, I cannot provide a comprehensive survey of recent work. So we must begin by limiting the scope of our inquiry. First, we will concentrate on work done in English or translated into English, simply to ensure ease of access to the texts under examination. Second, we will concentrate on work done in the last 15 years or so, since the early 1990s. Third, we will concentrate on those philosophers who treat both consciousness and the body together. Thus we will not treat philosophers who look at body representations in culture, nor philosophers who examine socio-political bodily practices with minimal or no reference to consciousness. Finally, even with the philosophers we choose to treat, we cannot be comprehensive and will instead make representative choices among their works. With that being said, we will have a fairly liberal definition of continental philosophy, operationally defined as that which makes (non-exclusive) reference to the classic phenomenology of Husserl, Heidegger, and Merleau-Ponty. Thus we will include the radical..

Francisco Varela’s work is a monumental achievement in 20th century biological and biophilosophical thought. After his early collaboration in neo-cybernetics with Humberto Maturana (“autopoiesis”), Varela made fundamental contributions to immunology (“network theory”), Artificial Life (“cellular automata”), cognitive science (“enaction”), philosophy of mind (“neurophenomenology”), brain studies (“the brainweb”), and East- West dialogue (the Mind and Life conferences). In the course of his career, Varela influenced many important collaborators and interlocutors, formed a generation of excellent students, and touched the lives of many with the intensity of his mind, the sharpness of his wit, and the strength of his spirit. In this essay, I will trace some of the key turning points in his thought, with special focus on the concept of emergence, which was always central to his work, and on questions of politics, which operate at the margins of his thought. I will divide Varela’s work into three periods – autopoiesis, enaction, and radical embodiment – each of which is marked by a guiding concept; a specific..

God has been called many things, but perhaps nothing so strange as the name of “lobster” which he receives in A Thousand Plateaus.1 Is this simple profanation a pendant to the gleeful anti-clericalism of Deleuze2, for whom there is no insult so wretched as that of “priest”?3 Certainly, on one level. But it is also a clue to Deleuze’s ability to use a traditional concern of theology, the name of God, to intervene in the most basic questions of Western philosophy, in this case, the interchange of theology, biology and politics inherent in the question of nature and the organism.
