Against the tendency to regard Deleuze as a materialist and a naturalistic thinker, I argue that his core philosophical writings involve commitments that are incompatible with contemporary scientific naturalism. He defends different versions of a distinction between philosophy and natural science that is inconsistent with methodological naturalism and with the scientific image of the world as a single causally interconnected system. He defends the existence of a virtual realm of entities that is irreconcilable with ontological naturalism. The difficulty of reconciling (...) Deleuze’s philosophy with ontological naturalism is especially apparent in his recurrent conception of pure events that are irreducible to their incarnation in bodies and states of affairs. In the last section of this essay, I canvass some of the ways in which Deleuze’s thought might be reconciled with a more liberal, pluralist and ethical naturalism that he identified in an early essay on Lucretius.

Can a naturalist earn the right to talk of a shared empirical world? Hume famously thought not, and contemporary stipulative naturalists infer from this inability that the demand is somehow unnatural. The critical naturalist, by contrast, claims to earn that right. In this paper, I motivate critical naturalism, arguing first that stipulative naturalism is question begging, and second, that the pessimism it inherits from Hume about whether the problem can be solved is misplaced. Hume's mistake was to mis-identify exemplary contexts (...) of thought: thought is a kind of action, better exemplified at the backgammon table or the dinner party than in the study. By earning the right to this environment-involving conception of thought, the critical naturalist can address, rather than avoid, the explanatory problem Hume uncovered. (shrink)
