Gilles Deleuze (1925-1995) - specifically those that address recent theological appropriations of his thought. As readers of this blog would likely expect, I'm particularly interested in relating him to Whiteheadian process thought. I've mentioned him before on the blog as a thinker who has revived interest in speculative philosophy/cosmology/metaphysics amongst certain postmodern thinkers. While post-Heideggerian philosophers like Derrida were convinced that all metaphysics are inescapably totalizing and essentializing ways of thinking, which thereby subordinate difference to a higher/transcendent unity, Deleuze called himself a "pure metaphysician" - albeit one who attempted to think difference without any underlying principle of absolute unity or ultimate foundation. So while the poststructuralist tradition of Derrida and Foucault rejected ontology because it supposedly always makes us think that what appears to us is the natural order of things (rather than contingent, constructed, an effect of difference, etc), a Deleuzian poststructuralism calls for an alternative ontology. As Todd May explains, although Deleuze agreed with Derrida and Foucault in their view that difference must not be repressed by ontological identification - as it so often has been in the history of philosophy - he did not agree "with their [anti-ontological] cure" to this perennial problem.
His metaphysics of difference are in a sense a radicalization of Spinoza, who Deleuze called "the Christ of philosophers" because he "revealed" (so to speak) a philosophy of immanence without transcendence more than any other Western philosopher. Yet Deleuze rejects Spinoza's reliance on substance metaphysics and develops a neo-Spinozan pluralistic monism. Spinoza's one absolute substance is dissolved by Deleuze into a pluralized "plane of immanence." He developed a complex metaphysical system that prioritizes difference over unity, becoming over being, and immanence over transcendence. Deleuze offers a truly experimental metaphysics, an "anti-systematic," "open-ended," "acentered," and radically "uncertain" system. He carefully developed his concepts with the goal of affirming this life over any "super-sensible" or transcendent world. In short, he argues that the plane of immanence is filled with innumerable virtual events, constantly coming in and going out of existence, that become actualized on the plane of organization. This is very much like the traditional philosophical distinction between nature naturing and nature natured (as in Robert Corrington's "ecstatic" or "aesthetic" naturalism).
The plane of immanence is like a "chaos" of seething potentialities moving at infinite speed - fully real while neither ideal nor actual. Virtual events on the plane of immanence are also called by Deleuze "pure singularities," "mad particles," "free intensities," and "nomadic singularities." These "molecular" potentialities become actualized into "molar aggregates" or layered "strata" on the plane of organization as what we experience as sensible matter and identities. So like anything else, we as humans are constituted by these dynamic and self-creative molecular events. In the Deleuzian nondual "chaosmology," there is no sharp line between mind and matter, nature and culture, human and non-human, or any other traditional ontological dualism. Identities are only "effects" of difference. Subjects are only relatively stable repetitions of differential relations. Nothing is static. Everything is in constant becoming. No transcendence, absolute presence, representations, hierarchies, dualisms, or clear identities. Everything is immanent, heterogeneous, dynamic processes of becoming, self-creative, and relationally constituted. This is Deleuze "in a nutshell" - if there is such a thing!
If you know Whitehead's philosophy of organism, you're probably sensing a lot of parallel concepts here. In fact, I agree with commentators like Catherine Keller, Roland Faber, Steven Shaviro, and Luke Higgins that the metaphysics of Deleuze and Whitehead are extremely close. This is not entirely surprising since Deleuze believed that Whitehead's Process and Reality was one of the greatest works of philosophy in the 20th century. But where do they disconnect? I'm still working on this question (I plan to work through Deleuze's primary sources more thoroughly this fall), but here are my initial observations:
2) Deleuze implicitly rejects Whitehead's panentheistic God in favor of something more like a pluralistic pantheism: while Whitehead tends to be interpreted as a type of panentheist, it is difficult to read Deleuze along these lines - even though Deleuze looked quite favorably upon Whitehead's notion of God in his late work The Fold. Like Spinoza, Deleuze is more adequately interpreted as a kind of pantheist. When he is appropriated in a theological way by thinkers like Clayton Crockett, Luke Higgins, and
