Plutarch

While it is well known that Plutarch’s De facie in orbe lunae was a major source of inspiration for Galileo’s Sidereus nuncius, its influence on his Dialogo sopra i due massimi sistemi del mondo, and especially on his views on gravity, has not been sufficiently explored. This essay offers the first systematic comparison of Plutarch’s and Galileo’s accounts of gravity by focusing on four themes: the thought experiment of a stone falling in a tunnel passing through the center of the (...) Earth; the account of gravity as a tendency to unite with the whole; the view that the Moon is a separate center of attraction; and the impossibility of attraction by an incorporeal point. The essay analyzes the role that these themes play in De facie and in the Dialogo, trying to understand how Galileo appropriated, reworked, and expanded on Plutarch’s views. (shrink)

In his dialogue, 'Non posse suaviter vivi secundum Epicurum', Plutarch of Chaeronea criticizes Epicurus for not believing that the gods are provident over human affairs and for not believing that our souls survive death. However, Plutarch’s arguments are striking in that they do not offer any theoretical justification for believing either of these religious claims to be true; rather, they aim to establish that we are practically justified in adopting them if we follow Epicurus’s rule that the goal of belief (...) is not truth in its own right, but mental tranquility. I argue that this form of argument assumes a novel justificatory theory of religious belief, based in Epicurean thought, that I call ‘strong doxastic hedonism.’. (shrink)

Athenaeus of Attalia distinguishes two types of exercise or training (γυμνασία) that are required at each stage of life: training of the body and training of the soul. He says that training of the body includes activities like physical exercises, eating, drinking, bathing and sleep. Training of the soul, on the other hand, consists of thinking, education, and emotional regulation (in other words, 'philosophy'). The notion of 'training of the soul' and the contrast between 'bodily' and 'psychic' exercise is common (...) in the Academic and Stoic traditions Athenaeus is drawing from; however, he is the earliest extant medical author to distinguish these kinds of training and to treat them as equally important aspects of regimen. In this paper, I propose some reasons why he found this distinction useful, and I examine how he justified incorporating it into his writings on regimen, namely by attributing Plato's beliefs about regimen to Hippocrates, a strategy Galen would adopt well over a century later.

Thanks to the work of Stephen Newmyer, Plutarch’s importance for modern philosophical debates concerning animal rationality and rights has been brought to the forefront. But Newmyer’s important scholarship overlooks Plutarch’s commitment to a range of rational functions that can be ascribed to animals of various sorts throughout the Moralia. Through an application of the ‘spectrum of animal rationality’ described in the treatise On Moral Virtue to the dialogues where his interlocutors explore the rational capacities of non-human animals (especially Whether Land (...) or Sea Animals are Smarter and Gryllus), this article argues that Plutarch’s commitment to a broad and inclusive sense of ‘reason’ conditions any positive account of animal rationality. Rather, any suggestions of the rational capacities of non-human animals are deeply implicated in Plutarch’s universal system of reason, which differentiates grades of rationality to animals based on natural difference – not unlike his contemporary Stoics. While modern proponents of animal rationality might find some of Plutarch’s ideas unpalatable, the upshot of this study is a fuller sense of Plutarch’s articulate and inclusive sense of reason, which is able to accommodate not only Platonist and Peripatetic notions, but also those of the Stoics and Epicureans, who are especially singled out in the humorous dialogue Gryllus. Thus, Plutarch’s ‘eclecticism’ can be explained as a deep commitment to a universal notion of ‘reason’, marked by a range of functions accessible to all animals – including his philosophical enemies.

Plutarch is often seen as a dualist philosopher. Yet, when one studies the texts which are most often quoted to back such an opinion, the so‑called dualist doxographies in De Iside et Osiride and in De animae procreatione, one is actually lead to think otherwise. When they are replaced in their context, it so happens that these texts describe the conditions to obtain harmony and the mixing of the contraries which are both necessary to the birth and to the very (...) existence of the universe. However, harmony and mixing cannot be obtained without the receptacle of the contraries that constitute them. Far from being a simple intermediary, this receptacle, which takes different aspects in the different treatises, is indeed a constituent principle according to Plutarch. Without it, there can be neither encounter nor opposition of the contraries, and so, paradoxically, precisely because it is a guarantee of dualism, it makes dualism disappear. Dualism then turns out to be a mere preparatory step in the elaboration of a really triadic philosophy. (shrink)

According to Plutarch, the theory of psychological disharmony relies on the Platonic music harmony. When Plato refers to music harmony, he means the kind of harmony where the concept of God is the source through which all beings emanate. The mental passions define the quality of human character and consequently develop the social man. As far as the Aristotelian ethical theory is concerned, morality does not condemn the passions, because it has a clear ontological and anthropological basis. The Stoics stress (...) that a trait of the human soul is sociality, and that happens because all human beings are under the law of sympathy and constitute a whole. At medieval times, Boethius portrays the middle age social conditions which also resemble with our postmodern societies. (shrink)

Plutarch is committed to geometric atomism, the Platonic theory that derives the material elements from regular polyhedric shapes. An essential feature of this theory is that qualitative properties are not primitive, but supervene on more fundamental, quantitatively describable properties, such as the size, shape, mass or weight of the atoms, their solidity, position, arrangement and kinetic interactions. Plutarch recognises that the geometric account provides the causal explanation for phenomenal and other qualitative properties. He praises Plato and Democritus for their theoretical (...) accomplishment in this domain. Yet in his reply to Colotes, he criticises Epicurus and Democritus because of their atomism, and claims that it is not possible to derive qualities from qualityless atoms. Plato’s theory is different, he claims, as it does not make the primordial corpuscles qualityless and unchanging. I examine three possible explanations for this discrepancy: Plutarch’s argument against Democritus serves purely polemical purposes; Plutarch is not fully aware of the theoretical force and import of geometric atomism; he disposes of a more sophisticated account of geometric atomism, containing assumptions unknown to us that save the model from the objections directed at Democritus.

Starting with the reference to “Plato’s dictum” that Freud added in the second last page of the first edition of The Interpretation of Dreams, the author explains the convergences between the conception of dreams expounded by Plato in the Republic and Freud’s fundamental insights. The analysis of bibliographic sources used by Freud, and of his interests, allow than to suppose not only that Freud omitted to acknowledge the Plato’s theoretical genealogy of “the Via Regia to the unconscious”, but also the (...) possibility that the Republic constituted a tacit source of inspiration for the composition of The Interpretations of dreams. -/- Muovendo dal richiamo al «detto di Platone» inserito nella penultima pagina della prima edizione de "L’interpretazione dei sogni" di Freud (1899), vengono preliminarmente esposte le convergenze tra la concezione del sogno di Platone esposta ne "La Repubblica" e le intuizioni poste alla base dell’edificio freudiano. Alla luce delle fonti testuali citate e utilizzate da Freud, e dei suoi interessi, viene poi avanzata l’ipotesi che egli non soltanto abbia omesso di riconoscere la genealogia teoretica platonica della «via regia che porta alla conoscenza dell’inconscio» (p. 282), ma che l’antico dialogo abbia potuto rappresentare una fonte tacita di ispirazione per la composizione de "L’interpretazione dei sogni".

Lieve Van Hoof's welcome addition to the study of Plutarch's moral works focuses on a group of writings that discuss practical issues, ranging from coping with exile and curbing one's curiosity to proper nutrition and table manners. Van Hoof collectively refers to these treatises as "Plutarch's practical ethics," setting them apart from Plutarch's theoretical works, which discuss key philosophical concepts.Van Hoof begins by noting with regret the scholarly neglect of Plutarch's practical ethics. Historians of philosophy, who usually read Plutarch's moral (...) works as sourcebooks on academic philosophical theories, are frustrated when confronted with Plutarch's practical treatises, where references to academic ..

The paper focuses on the representation of pedagogical and political communication between (and around) Plato, Dion and Dionysius II in Plutarch's Life of Dion. Plutarch's narrative invokes both the Platonic critique of writing as an inadequate medium for teaching philosophy, and the polarity between free oral speech and writing as a symptom of tyranny. It is argued that the Life espouses but also complicates and implicitly interrogates the opposition between writtenness and orality across the philosophical and the political domain, thus (...) constituting a rich intertextual response, from an Imperial Platonist author, to the Platonic concerns about the written word.

Plutarch's epistolary essay, That a Philosopher ought to Converse especially with Men in Power, has been neglected because not recognized for what it is: an attempt to persuade an addressee attached to Epicurean principles that his attraction to political friendship should be honoured rather than eradicated. Rather than attack Epicureanism, Plutarch attempts to expand the horizons of a hedonic and utilitarian ethics so as to include noble benefaction on a political scale. This requires him to undermine the Epicurean insistence on (...) restricting friendship to private like-minded circles, and to expand its hedonism into a political utilitarianism. Unlike Cicero's De Finibus , Plutarch's letter offers an indirect critique, and preserves elements of Epicurean ethics suitable to the moderating influence a friend and advisor can exert on the statesman's eros.

This paper examines Plutarch's treatment of education in the Parallel Lives. Beginning with a close reading of Them. 2, it identifies two distinct ways in which Plutarch exploits the education of his subjects: in the first, a subject's attitude to education is used to illustrate a character presented as basically static (a 'static/illustrative' model); in the second, a subject's education is looked at in order to explain his adult character, and education is assumed to affect character (a 'developmental' model). These (...) two models are often associated with two different forms of discourse: anecdotal for the static/illustrative model and analytical for the developmental. The developmental model, furthermore, is closer to Plutarch's thinking in theoretical discussions of character in the Moralia; the static/illustrative model to Plutarch's treatment of character in the Lives more generally, where anecdotal treatments predominate. The coexistence of these two models is probably to be seen as the result of a tension between Plutarch's philosophical thinking and his biographical practice: those few passages in the Lives which assume a developmental model occur in contexts where either Platonic texts or the activity of philosophers are being discussed.
