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)

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.

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.

Rather than considering ordinary language as deficient and incapable of grasping the structure of reality, the Stoics set out a theory, based on their notion of a lekton, by which ordinary language is a reflection of the structure of lekta which themselves are constitutive of reality.

ABSTRACT: An introduction to Stoic logic. Stoic logic can in many respects be regarded as a fore-runner of modern propositional logic. I discuss: 1. the Stoic notion of sayables or meanings (lekta); the Stoic assertibles (axiomata) and their similarities and differences to modern propositions; the time-dependency of their truth; 2.-3. assertibles with demonstratives and quantified assertibles and their truth-conditions; truth-functionality of negations and conjunctions; non-truth-functionality of disjunctions and conditionals; language regimentation and ‘bracketing’ devices; Stoic basic principles of propositional logic; (...) 4. Stoic modal logic; 5. Stoic theory of arguments: two premisses requirement; validity and soundness; 6. Stoic syllogistic or theory of formally valid arguments: a reconstruction of the Stoic deductive system, which consisted of accounts of five types of indemonstrable syllogisms, which function as nullary argumental rules that identify indemonstrables or axioms of the system, and four deductive rules (themata) by which certain complex arguments can be reduced to indemonstrables and thus shown to be formally valid themselves; 7. arguments that were considered as non-syllogistically valid (subsyllogistic and unmethodically concluding arguments). Their validity was explained by recourse to formally valid arguments. (shrink)

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)
