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.

This paper examines some neglected Chrysippean fragments on insecure apprehension (κατάληψις). First, I present Chrysippus’ account of how non-Sages can begin to fortify their insecure apprehension and upgrade it into knowledge (ἐπιστήμη). Next, I reconstruct Chrysippus’ explanation of how sophisms and counter-arguments lead one to abandon one’s insecure apprehension. One such counter-argument originates in the sceptical Academy and targets the Stoic claim that insecure apprehension can be acquired on the basis of custom (συνήθεια). I show how Chrysippus could defend the (...) possibility of custom-based apprehension, while also denying that there is custom-based knowledge. (shrink)

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.

Demonstrates the sophistication of Seneca’s Stoicism by setting his contributions within the context of his school. Seneca’s contributions to physics, metaphysics, logic, determinism, theodicy and eschatology are set within a systematic reconstructions of Stoic positions. Ample documentation of sources and scholarship as well as the thematic, handbook-like structure allow for this book to be used as a look-up tool and introduction to the Stoic cosmos and the place of humans within it. -/- There are a number of new readings and (...) interpretations, e.g. concerning the corporeality of the principles; mixture (krasis di’ holôn); the elements and pneuma; identity; the relation of God and humans; Seneca’s attitude to logic; Seneca’s philosophy of time; the role of lekta in defining reality and action; Stoic and Senecan theodicy; Seneca’s contribution to the determinism debate.

Belief and Truth: A Skeptic Reading of Plato explores a Socratic intuition about belief, doxa -- belief is "shameful." In aiming for knowledge, one must aim to get rid of beliefs. Vogt shows how deeply this proposal differs from contemporary views, but that it nevertheless speaks to intuitions we are likely to share with Plato, ancient skeptics, and Stoic epistemologists.

Seneca's Letters to Lucilius are a rich source of information about ancient Stoicism, an influential work for early modern philosophers, and a fascinating philosophical document in their own right. This selection of the letters aims to include those which are of greatest philosophical interest. In addition to examining the philosophical content of each letter, Brad Inwood's commentary discusses their literary and historical background.

For this Clarendon Paperback, Dr Griffin has written a new Postscript to bring the original book fully up to date. She discusses further important and controversial questions of fact or interpretation in the light of the scholarship of the intervening years and provides additional argument where necessary. The connection between Seneca's prose works and his career as a first-century Roman statesman is problematic. Although he writes in the first person, he tells us little of his external life or of the (...) people and events that formed its setting. Miriam Griffin addresses the problem by first reconstructing Seneca's career using only outside sources and his de Clementia and Apocolocyntosis, whose political purposes are undisputed. In the second part of the book she studies Seneca's treatment of subjects of political significance, including his views on slavery, provincial policy, wealth, and suicide. On the whole, the word of the philosopher is found to illuminate the work of the statesman, but notable exceptions emerge, and the links that are revealed vary from theme to theme and rarely accord with traditional autobiographical interpretations of Seneca's works.

I argue that comparisons of Stoic virtue to stochastic skills — now standard in the secondary literature on Stoicism — are based on a misreading of the sources and distort the Stoic position in two respects. In paradigmatic stochastic skills such as archery, medicine, or navigation the value of the skill’s external end justifies the existence and practice of the skill and constitutes an appropriate focus of rational motivation. Neither claim applies to virtue as the Stoics understand it. The stochastic (...) model of virtue almost certainly originated with Carneades and should be distinguished clearly from the Stoic account. Doing so clarifies the Stoic position and shows that it anticipates what Thomas Hurka calls a modern view of value. (shrink)

Looks at evidence for Seneca's reception of Stoic epistemology and argues that such knowledge was a factor in determining his style of writing and didactic methods.

Pendant cinq siecles, de 300 av. J.C. jusqu'au crepuscule de Marc Aurele, la philosophie stoicienne domina la culture antique. Encore aujourd'hui, notre grammaire, notre logique et notre linguistique sont les heritieres plus ou moins conscientes de l'une des trois parties de cette philosophie, la dialectique, qui fut, dans sa forme classique, l'oeuvre de Chrysippe (280-204 av. J.C.). Ce livre est la premiere reconstruction synthetique de la dialectique stoicienne dans son ensemble. Son point de vue est en outre entierement nouveau. En (...) effet, pour l'auteur, les stoiciens n'avaient pas une logique au sens moderne du terme, mais une dialectique, c'est-a-dire une technique de l'argumentation dialoguee. Sa conception complexe, a premiere vue multiple et equivoque, recoit ainsi un eclairage inedit, qui permet de comprendre son originalite et d'en reinterpreter la place dans l'ensemble du systeme. Cela nous permet aussi de mieux comprendre le sens des disciplines qui en sont les heritieres infideles. (shrink)

An account of the role and the nature of logic in imperial stoic philosophy which challenges the prevailing orthodoxy and presents a novel interpretation of this crucial period of ancient philosophy.

The earliest philosophers thought deeply about ethical questions, but Aristotle founded ethics as a well-defined discipline. Brad Inwood focuses on the reception of Aristotelian ethical thought in the Hellenistic and Roman worlds and explores the thinker's influence on the philosophers who followed in his footsteps from 300 BCE to 200 CE.
