In this essay I explore the nature of Deleuze’s commitment to an affirmative naturalism that is based on certain Epicurean principles and insights. The essay is divided into two main parts. In the first part I bring to light some of the key features of Lucretius’s great poem on the nature of things, and I do so with the aid of Bergson and his reading of the teaching as fundamentally melancholic. In the second part I switch my attention to Deleuze (...) and show how he links together physics and ethics as a way of providing an emancipatory and affirmative philosophy of life and one that aims to defeat sadness. In the conclusion I return to the question of melancholy and indicate how the problem might be best negotiated. (shrink)

Overview of Epicurean physics and epistemology, ending with a critical discussion of Cicero's report on Epicurean theology.

A fairly long (~15,000 word) overview of ancient theories of freedom and determinism. It covers the supposed threat of causal determinism to "free will," i.e., the sort of control we need to have in order to be rightly held responsible for our actions. But it also discusses fatalistic arguments that proceed from the Principle of Bivalence, what responsibility we have for our own characters, and god and fate. Philosophers discussed include Aristotle, Epicurus, the Stoics, Carneades, Alexander of Aphrodisias, and Plotinus. (...) Plato is mentioned in passing a few times in connection with other philosophers. (shrink)

Epicurus' "On Nature" 25 is the key text for anti-reductionist interpretations of Epicurus' philosophy of mind. In it, Epicurus is trying to argue against those, like Democritus, who say that everything occurs 'of necessity,' and in the course of this argument, he says many things that appear to conflict with an Identity Theory of Mind and with causal determinism. In this paper, I engage in a close reading of this text in order to show that it does not contain any (...) clear statement of either a doctrine of radically emergent properties and "downwards causation" (contra David Sedley) or of the non-reducibility of the mental to the atomic (contra Julia Annas). I argue that Epicurus' main thesis is that we cannot consistently argue against our conception of ourselves as rational agents, and that it is our reason that allows us to reform our characters, control our actions, and blame and praise one another appropriately. The way that Epicurus describes the development and causal efficacy of reason in "On Nature" book 25 is consistent both with reductionism and (more surprisingly) with causal determinism. (shrink)

Este artigo compara e contrasta dois conceitos filosóficos provenientes de distintas linhagens de pensamento: de um lado, o _clinamen _de Lucrécio; do outro, o _conatus _de Espinosa. O que fomentou minha pesquisa foi uma conjugação dessas noções tal como proposto por Deleuze no apêndice de seu _Logique du sens_. Nesse sentido, a primeira seção está orientada tendo em vista uma elucidação da filosofia de Lucrécio — consequentemente, também a de Epicuro — e, especificamente, uma interpretação do desvio dos átomos ou (...) _clinamen_ em combinação com o tópico da liberdade. A segunda seção se dedica a clarificar a metafísica de Espinosa e a acomodação do tema da liberdade dentro de seu robusto enquadramento necessitário, entrelaçado com o motivo do _conatus _ou esforço de auto-preservação. Contra a leiture de Deleuze, entretanto, argumentarei que _clinamen _e _conatus _pertencem à sistemas metafísicos que são praticamente incompatíveis e que corroboram um entendimento diferente sobre liberdade e necessidade.

Some significant receptions of Epicurean philosophy take place in nineteenth century European thought. For Marx, writing in the 1840s, and in defiance of Hegel’s negative assessment, Epicurus is the ‘greatest representative of the Greek enlightenment’,1 whilst for Jean-Marie Guyau, writing in the 1870s, Epicurus is the original free spirit, ‘Still today it is the spirit of old Epicurus who, combined with new doctrines, works away at and undermines Christianity.’ 2 For Nietzsche, Epicurus is one of the greatest human beings to (...) have graced the earth and the inventor of ‘heroic-idyllic philosophizing’.3 Here my focus is on the reading of Epicureanism to be found in Bergson’s commentary on Lucretius’s remarkable poem, De Rerum Natura. For Bergson the task Lucretius sets himself is a ‘pioneering one’, one that will serve humanity, in particular making the Romans aware of previously unknown or misunderstood truths. In order to demonstrate these truths with precision it was necessary for Lucretius to be acquainted with Greek philosophy, and especially the teaching of Epicurus. (shrink)
