This paper seeks to elucidate the distinctive nature of the rational impression on its own terms, asking precisely what it means for the Stoics to define logikē phantasia as an impression whose content is expressible in language. I argue first that impression, generically, is direct and reflexive awareness of the world, the way animals get information about their surroundings. Then, that the rational impression, specifically, is inherently conceptual, inferential, and linguistic, i.e. thick with propositional content, the way humans receive incoming (...) information from the world. When we suspend certain contemporary assumptions about propositional content, the textual evidence can be taken at face value to reveal why, for the Stoics, rational impressions are called thoughts (noēseis) and how the Stoics’ novel semantic entities called lekta (roughly, the meanings of our words) depend on rational impressions for their subsistence.

Essays on Aristotle's Sea-Battle, Lazy Argument, Argument Reaper, Diodorus' Master Argument -/- The book is devoted to the ancient logical theories, reconstruction of their semantic proprieties and possibilities of their interpretation by modern logical tools. The Ancient arguments are frequently misunderstood in modern interpretations since authors usually have tendency to ignore their historical proprieties and theoretical background what usually leads to a quite inappropriate picture of the argument’s original form and mission. Author’s primary intention was to draw attention to the (...) complexity of some historical arguments and to the theoretical context in which arguments were created, circulated, developed, and finally tuned. Four well-known ancient arguments – with a common central subject related to the future contingencies problem – are reconstructed from available historical sources: “The Sea Battle”, which is drawn from Aristotle’s treatise De Interpretatione; two arguments, usually ascribed to the Stoics, “The Lazy Argument” and “The Reaper”; “The Master Argument” of the Megarian philosopher Diodorus. Arguments are linguistically and semantically detaily analyzed, formally presented by reflecting some relevant corresponding hypotheses based on physical or logical theories of their ancient authors, and finally covered by appropriate logical tools familiar to a modern reader. Two appendices are added at the closing part of the book. One covering some assumptions relevant for understanding of rival streams in ancient theories of meaning related to the nature of names and naming; the other is devoted to the ancient understanding of logical proposition and attempts to find an adequate Latin translation of the Greek delicate philosophical term “ἀξίωμα”.

The Stoics’ theory of kataleptic impressions looks different once we attend to their analysis of the Sorites paradox. In defending this view, I reject the long-standing assumption that the Stoics develop their theory by focusing on sensory impressions. The Stoic approach to vagueness shows, for example, that non-sensory impressions can be seemingly indistinguishable by belonging to a series. It also draws attention to an understudied dimension of Stoic theory: in aiming to assent only to kataleptic impressions, one aims to avoid (...) not only assent to false impressions but also assent to those that are neither true nor false.

We focus on the question of how expertise as conceived by the Stoics interacts with the content of impressions. In Section 1, we situate the evidence concerning expert perception within the Stoic account of cognitive development. In Section 2, we argue that the content of rational impressions, and notably of expert impressions, is not exhausted by the relevant propositions. In Section 3, we argue that expert impressions are a subtype of kataleptic impressions which achieve their level of clarity and distinctness (...) due to the contribution of expertise. In Section 4, we argue that the expertise in living well not only allows the wise person to assent correctly but also affects the content of her impressions. We suggest that these two models – one’s attitude toward an impression being informed by expertise, and one’s impressions being affected by expertise – might characterize distinct stages of cognitive development. Stoic wisdom is not only a matter of the way one assents to one’s impressions but also a matter of the condition of one’s soul and, consequently, of the kinds of impressions one even entertains. Expertise offers a model of how cognitive and discriminatory improvement through practice and effort can transform the non-wise into the wise. A reading on which the content of impressions is not exclusively propositional illuminates a further aspect of this transformation. If the same propositions are accessible through impressions with different non-propositional content, we can account for cases in which the novice and the expert entertain the same proposition.

The Stoics offer us a very puzzling conception of causation and an equally puzzling ontology. The aim of the present paper is to show that these two elements of their system elucidate each other. The Stoic conception of causation, I contend, holds the key to understanding the ontological category of incorporeals and thus Stoic ontology as a whole, and it can in turn only be understood in the light of this connection to ontology. The thesis I defend is that the (...) Stoic incorporeals are to be understood as effects, as effects of the causality of bodies. What is gained by this thesis? First, it explains how the seemingly heterogeneous item of ‘sayables’ (lekta) fits into the category of incorporeals. Second, it allows for a new interpretation of the two verbs with which the Stoics characterize the way of being of incorporeals, huphistanai and huparchein. And, third, it sheds light on the peculiar features of the Stoic conception of causation. (shrink)

En este artículo se ofrece un análisis de la teoría estoica de la acción con el objetivo de solucionar un problema que la teoría aristotélica no tiene, a saber, cómo se adquiere el conocimiento práctico mínimo que un agente debe tener para llevar a cabo una acción. Se estudian nociones estoicas como phantasía, ormée y kathéekontos desde las perspectivas epistemológica, práctica e incluso psicológica.

The Stoic philosopher Chrysippus wrote extensively on the liar paradox, but unfortunately the extant testimony on his response to the paradox is meager and mainly hostile. Modern scholars, beginning with Alexander Rüstow in the first decade of the twentieth century, have attempted to reconstruct Chrysippus? solution. Rüstow argued that Chrysippus advanced a cassationist solution, that is, one in which sentences such as ?I am speaking falsely? do not express propositions. Two more recent scholars, Walter Cavini and Mario Mignucci, have rejected (...) Rüstow's thesis that Chrysippus used a cassationist approach. Each has proposed his own thesis about Chrysippus? solution. I argue that Rüstow's view is fundamentally correct, and that the cassationist thesis gains greater plausibility when viewed in light of a passage in Sextus Empiricus? Adversus mathematicos that the previous commentators have ignored, and when understood within the broader context of Stoic logical theory and philosophy of language. I close with a brief remark on the significance of Chrysippus? work for the modern debate on the semantic paradoxes. (shrink)

One of the most intriguing claims of Stoic logic is Chrysippus's denial of the modal principle that the impossible does not follow from the possible. Chrysippus's argument against this principle involves the idea that some propositions are ?destroyed? or ?perish?. According to the standard interpretation of Chrysippus's argument, propositions cease to exist when they are destroyed. Ide has presented an alternative interpretation according to which destroyed propositions persist after destruction and are false. I argue that Ide's alternative interpretation as well (...) as some versions of the standard interpretation conflict with Stoic doctrines about the nature of propositions. I propose another version of the standard interpretation based on Frede's account of the Stoic theory of the proposition. I hold that this version of the standard interpretation both escapes Ide's objections and is consistent with Stoic logic and philosophy of language. (shrink)

Often, when Seneca wants to defend a thesis that seems original to him in relation to the Stoic school, he claims to enjoy distracting himself with subtle games that quickly become boring puzzles....

This article argues that Epictetus employs the terms orexis and hormê in the same manner as the older Stoics. It then shows, on the basis of this claim, that the older Stoics recognized a distinction between dispositional and occurrent forms of motivation. On this account of Stoic theory, intentional action is in each instance the product of two forms of cognition: a value ascription that attributes goodness or badness to some object, conceiving of its possession as beneficial or harmful to (...) the agent, together with a situational judgment about appropriate action. The resulting interpretation suggests that the Stoic theory of motivation as a whole — and not merely the Stoic analysis of the pathê — has the basic shape of a practical syllogism, with more psychological depth than commentators have recognized.

Simply by formulating a question about the nature of ancient Greek poetry or music, any modern English speaker is already risking anachronism. In recent years especially, scholars have reminded one another that the words ‘music’ and ‘poetry’ denote concepts with no easy counterpart in Greek. μουσική in its broadest sense evokes not only innumerable kinds of structured movement and sound but also the political, psychological and cosmic order of which song, verse and dance are supposed to be perceptible manifestations. Likewise, (...) ποίησις and the ποιητικὴ τέχνη can encompass all kinds of ‘making’, from the assembly of a table to the construction of a rhetorical argument. Of course, there were specifically artistic usages of these terms—according to Plato, ‘musical and metrical production’ was the default meaning of ποίησις in everyday speech. But even in discussions which restrict themselves to the sphere of human art, we find nothing like the neat compartmentalization of harmonized rhythmic melody on the one hand, and stylized verbal composition on the other, which is often casually implied or expressly formulated in modern comparisons of ‘music’ with ‘poetry’. For many ancient theorists the City Dionysia, a dithyrambic festival and a recitation of Homer all featured different versions of one and the same form of composition, a μουσική or ποιητική to which λόγοι, γράμματα and συλλαβαί were just as essential as ἁρμονία, φθόγγοι, ῥυθμός and χρόνοι.

ABSTRACTIn this article I argue that Sartre’s notions of nothingness and “negatity” are not, as he presents it, primarily reactions to Hegel and Heidegger. Instead, they are a reaction to an ongoing struggle with Husserl’s notion of intentionality and related notions. I do this by comparing the criticism aimed at Husserl in Sartre’s Being and Nothingness to that presented in his earlier work, The Imagination, where he discusses Husserl more elaborately. Furthermore, I compare his criticism to Husserl’s own criticism of (...) the “doctrine of immanent objects”, in order to show that Sartre’s notion of nothingness is a continuation of Husserl’s criticism, and that he turns Husserl’s own arguments against himself.

This article analyzes the definition of res in two places of Augustine's works, namely, De dialectica, ch. 5, and De doctrina christiana, I, ii, 2. In these places, the concept of res is treated in relation to the concept of sign (signum). In the first text, Augustine suggests that with our words we mean things by expressing ideas of those things. According to the second text, something is a thing only insofar as it is not being used currently as a (...) sign, given that anything can be used as a sign. (shrink)

At Varro LL VI.56 and SE M 8.275-276, we find reports of the Stoic view that children and articulate non-rational animals such as parrots cannot genuinely speak. Absent from these testimonia is the peculiar case of the superficiality of the actor’s speech, which appears in one edition of the unstable text of PHerc 307.9 containing fragments of Chrysippus’ Logical Investigations. Commentators who include this edition of the text in their discussions of the Stoic theory of speech do not offer a (...) univocal account of the superficiality of the parrot’s, the child’s, and the actor’s speech. In this paper, I offer a reconstruction of the Stoic account of genuine and superficial speech and show that not only is there an account of superficial speech that univocally explains the superficiality of the speech of parrots, children, and actors, but that this account challenges traditional assumptions about the entities at the heart of the Stoic theory of language—lekta. It will turn out that genuine speech is the expression of a lekton by way of performing a speech act, and that this account of superficial speech can be used to explain other linguistic phenomena that are of interest to the Stoics, such as sentences in insoluble sophisms and sentences containing demonstratives that do not refer to anything in the subject term. Importantly, my reconstruction shows, against the near consensus view of lekta, that lekta do not primarily explain what makes an utterance meaningful. Rather, they primarily explain what makes an utterance an instance of genuine speech. (shrink)

Stoicism was one of the new philosophical movements of the Hellenistic period. The name derives from the porch (stoa poikilê) in the Agora at Athens decorated with mural paintings, where the members of the school congregated, and their lectures were held. Unlike ‘epicurean,’ the sense of the English adjective ‘stoical’ is not utterly misleading with regard to its philosophical origins. The Stoics did, in fact, hold that emotions like fear or envy (or impassioned sexual attachments, or passionate love of anything (...) whatsoever) either were, or arose from, false judgements and that the sage—a person who had attained moral and intellectual perfection—would not undergo them. The later Stoics of Roman Imperial times, Seneca and Epictetus, emphasise the doctrines (already central to the early Stoics' teachings) that the sage is utterly immune to misfortune and that virtue is sufficient for happiness. Our phrase ‘stoic calm’ perhaps encapsulates the general drift of these claims. It does not, however, hint at the even more radical ethical views which the Stoics defended, e.g. that only the sage is free while all others are slaves, or that all those who are morally vicious are equally so. Though it seems clear that some Stoics took a kind of perverse joy in advocating views which seem so at odds with common sense, they did not do so simply to shock. Stoic ethics achieves a certain plausibility within the context of their physical theory and psychology, and within the framework of Greek ethical theory as that was handed down to them from Plato and Aristotle. It seems that they were well aware of the mutually interdependent nature of their philosophical views, likening philosophy itself to a living animal in which logic is bones and sinews; ethics and physics, the flesh and the soul respectively (another version reverses this assignment, making ethics the..
