In this paper I offer a new interpretation of Stoic ontology. I aim to explain the nature of, and relations between, (i) the fundamental items of their physics, bodies; (ii) the incorporeal items about which they theorized no less; and (iii) universals, towards which the Stoic attitude seems to be a bizarre mixture of realism and anti-realism. In the first half of the paper I provide a new model to explain the relationship between those items in (i) and (...) (ii). This model clears up several problems in Stoicism and gives a precise answer to the question of how bodies and incorporeals differ in their mode of being. The second half of the paper considers the vexed issue of the status of those items in (iii), Stoic universals. (shrink)

The Stoics are famously committed to the thesis that only bodies are, and for this reason they are rightly called “corporealists.” They are also famously compared to Plato’s earthborn Giants in the Sophist, and rightly so given their steadfast commitment to body as being. But the Stoics also notoriously turn the tables on Plato and coopt his “dunamis proposal” that being is whatever can act or be acted upon to underwrite their commitment to body rather than shrink from it as (...) the Giants do. The substance of Stoic corporealism, however, has not been fully appreciated. This paper argues that Stoic corporealism goes beyond the dunamis proposal, which is simply an ontological criterion for being, to the metaphysics of body. This involves, first, an account of body as metaphysically simple and hence fundamental; second, an account of body as malleable and continuous, hence fit for blending (krasis di’ holou) and composition. In addition, the metaphysics of body involves a distinction between this composition relation seen in the cosmology, and the constitution relation by which the four-fold schema called the Stoic Categories proceeds, e.g. the relation between a statue and its clay, or a fist and its underlying hand. It has not been appreciated that the cosmology and the Categories are distinct — and complementary — explanatory enterprises, the one accounting for generation and unity, the other taking those individuals once generated, and giving a mereological analysis of their identity and persistence conditions, kinds, and qualities. The result is an elegant division of Plato’s labor from the Battle of Gods and Giants. On the one hand, the Stoics rehabilitate the crude cosmology of the Presocratics to deliver generation and unity in completely corporeal terms, and that work is found in their Physics. On the other hand, they reform the Giants and “dare to corporealize,” delivering all manner of predication (from identity to the virtues), and that work is found in Stoic Logic. Recognizing the distinctness of these explanatory enterprises helps dissolve scholarly puzzles, and harmonizes the Stoics with themselves. (shrink)

The Stoics have often been compared to the earthborn Giants in the Battle of Gods and Giants in Plato’s Sophist, but with diverging opinions about the lessons they drew in reaction to Plato. At issue are questions about what in the Sophist the Stoics were reacting to, how the Stoics are like and unlike the Giants, the status of being for the Stoics, and the extent to which they were Platonizing with their incorporeals. With these open questions in mind, I (...) reexamine the Sophist from the Stoic perspective, finding eight distinct challenges that are likely to have been salient to the Stoics, and offer a new account of the Stoics as responding to these challenges with an innovative ontology that prises apart something from being to make room for what is not, and a sophisticated one-world metaphysics that grounds everything there is in two fundamental bodies.

Void is at the heart of Stoic metaphysics. As the incorporeal par excellence, being defined purely in terms of lacking body, it brings into sharp focus the Stoic commitment to non-existent Somethings. This article argues that Stoic void, far from rendering the Stoic system incoherent or merely ad hoc, in fact reflects a principled and coherent physicalism that sets the Stoics apart from their materialist predecessors and atomist neighbors.

This paper rehabilitates the Stoic conception of blending from the ground up, by freeing the Stoic conception of body from three interpretive presuppositions. First, the twin hylomorphic presuppositions that where there is body there is matter, and that where there is reason or quality there is an incorporeal. Then, the atomistic presupposition that body is absolutely full and rigid, and the attendant notion that resistance (antitupia) must be ricochet. I argue that once we clear away these presuppositions about (...) body, the foundations of Stoic corporealism fall into place. Body is fundamental (not hylomorphic). The two fundamental principles (archai) are bodies: divine active reason (logos) and passive matter (hulē); and these two bodies are two, not matter and form all over again, nor actual and potential, but agent and patient. The independence of the two archai is no threat to the unity of the cosmos, however, because the Stoic theory of body allows for the complete coextension of the archai. The hylomorphic thinker rightly asks, what relation could be tighter than that of the wax and its shape? The Stoic replies: a causal relation, the interaction of agent and patient completely coextended in a through and through blend. (shrink)

The later Stoics, especially – and most notably – Posidonius of Apamea, allegedly the greatest polymath of his age and the last in a celebrated line of great philosophers of the ancient world, gradually developed the belief that all parts of the universe, either ensouled or not, were actually interconnected due to the omnipresent, corporeal, primordial kosmikon pyr which, according to Stoicism, pervades each being as the honey pervades the honeycomb. As for reasonable beings, in particular, kosmikon pyr takes the (...) form of logos. Due to that power, Posidonius believes, the phases of moon, for instance, can affect the succession of tides and ebb–tides; on the same grounds, the signs can have major effect on the course of events and, therefore, allow for divination. That kind of interconnectedness, apart from justifying the interdependentness of all beings to each other, testifies for an utter kinship between them, for sympatheia. In this short paper I intent to show that Posidonius’s approach has been promptly adopted and utilized by modern holistic theories concerning Environmental Ethics, especially by Arne Naess’s Deep Ecology and Ecosophy T, in the context of which notions such as kinship, interconnectedness, interdependentness and identification of all beings are key parameters for the articulation of their argumentation. I also intent to outline some essential – in my opinion – differences in the way Posidonius and Naess make use of the notion of interconnectedness, together with some inconsistencies which can be potentially fatal, at least as far as a system of ethics is concerned. This is because notions such as cosmic sympathy may possibly establish an interesting, even charming and influential cosmology or metaphysics, but when it comes to ethics, in my opinion, they can only provide shaky grounds for establishing a firm one, since they allow for deterministic views, which more or less leave no room for personal responsibility, to wit for personal praise or blame.

At the heart of the Stoic theory of modality is a strict commitment to bivalence, even for future contingents. A commitment to both future truth and contingency has often been thought paradoxical. This paper argues that the Stoic retreat from necessity is successful. it maintains that the Stoics recognized three distinct senses of necessity and possibility: logical, metaphysical and providential. Logical necessity consists of truths that are knowable a priori. Metaphysical necessity consists of truths that are knowable a (...) posteriori, a world order according to certain metaphysical principles and natures that god crafts within the constraints of matter. Finally, what is providentially necessary is what occurs according to the chain of fate, but only once it is in process or past. -/- The method of the paper is a close reading of Diogenes Laertius 7.75, adducing broad textual evidence along the way, to show that the Stoic theory of modality embraces Philonian possibility, both that which is capable of being true as a matter of logical consistency, and that which is possible according to the bare fitness of the entity. What differentiates the Stoics from Philo is their additional commitment to possibility as opportunity, resisting the collapse of determinism into necessity. (shrink)

This paper traces how the dualism of body and soul, cosmic and human, is bridged in philosophical and religious traditions through appeal to the notion of ‘breath’ (πνεῦμα). It pursues this project by way of a genealogy of pneumatic cosmology and anthropology, covering a wide range of sources, including the Pythagoreans of the fifth century BCE (in particular, Philolaus of Croton); the Stoics of the third and second centuries BCE (especially Posidonius); the Jews writing in Hellenistic Alexandria in the first (...) century BCE (Philo); and the Christians of the first century CE (the gospel writers and Paul). Starting from the early Pythagoreans, ‘breath’ and ‘breathing’ function to draw analogies between cosmogony and anthropogony – a notion ultimately rejected by Plato in the Timaeus and Aristotle in his cosmological works, but taken up by the Posidonius (perhaps following the early Stoa) and expanded into a rich and challenging corporeal metaphysics. Similarly, the Post-Hellenistic philosopher and biblical exegete Philo of Alexandria, who was deeply influenced by both Platonist and Stoic physics, approaches the cosmogony and anthropogony described in Genesis (1:1–3 and 1:7) through Platonist-Stoic philosophy, in his attempt to provide a philosophically rigorous explanation for why Moses employed certain terms or phrases when writing his book of creation. Finally, the chapter sees a determined shift in the direction of rejecting pneumatic cosmology for a revised pneumatic anthropogony in the writings of the New Testament: by appeal to the ‘Holy Spirit’ or ‘Holy Breath’ (πνεῦμα ἅγιον), early Christians effectively adapted the Stoic metaphysics of ‘breath’, with its notions of divine intelligence and bonding, to the prophetic and ecclesiastical project of building a Christian community conceived of as the ‘body of Christ’. Hence, the spiritual cosmogony of the Pythagoreans, Stoics, and Philo is effectively subordinated to the spiritual anthropogony that facilitates the construction of the Christian kosmopolis, only fully realised in the form of New Jerusalem, the ‘bride’ which, in tandem with the Holy Spirit, calls to the anointed. At the end of the Christian worldview, the kosmos of Greek philosophy is supplanted by the pneumatic kosmopolis. (shrink)

This paper considers the largely unexplored relation between Schopenhauer’s metaphysical system of Will and the philosophical therapy offered by Stoicism. By focusing on three key texts from disparate points in Schopenhauer’s philosophical career, as well as considering live debates regarding the metaphorical nature of his thought and his soteriology, I argue that the general view of straightforward opposition between himself and the Stoics is not the correct one. Rather, there are deep parallels to be found between the therapeutic aspects of (...) The World as Will and Representation (WWR) and the ethical recommendations made by the ancient Stoics. I will argue, further, that Schopenhauer recognised these similarities between his thought and Stoic ethics, often defending what he sees as the true essence of Stoicism. I conclude with some thoughts regarding the adoption of Stoic ideals by Nietzsche and Wittgenstein, in relation to their reading of Schopenhauer’s work. (shrink)

Can the Stoic conception of what is within our power be adapted to fit our scientifically informed view of nature in general and of human nature in particular? This paper argues that it can, but not without a revision of the Stoic’s classical dichotomy of power principle, namely that some things are up to us, while others are beyond our control. Given the extent to which the Stoic way of life flows from a certain conception of what (...) is real, a revision of the latter is bound to affect the former. The central argument is that for the modern Stoic, follow the facts means that nothing is entirely under our control just as nothing is entirely beyond it. Rather, things are more or less within my power, depending on the range of possibilities that living in accordance with a constantly evolving conception of nature affords. (shrink)

One of Leibniz’s more unusual philosophical projects is his presentation (in a series of unpublished drafts) of an argument for the conclusion that a time will necessarily come when “nothing would happen that had not happened before." Leibniz’s presentations of the argument for such a cyclical cosmology are all too brief, and his discussion of its implications is obscure. Moreover, the conclusion itself seems to be at odds with the main thrust of Leibniz’s own metaphysics. Despite this, we can (...) discern a serious and important point to Leibniz’s consideration of the doctrine, namely in what it suggests about the proper boundary between metaphysics and theology, on the one hand, and ordinary history (whether human or natural), on the other. And we can get a better sense of Leibniz purpose in the essays by considering them in the context of Leibniz's response to Thomas Burnet's "Telluris theoria sacra" (1681-89). Leibniz praises Burnet's history of earth for presenting a harmony between the principles of nature and grace, a harmony absent in the cosmogonies of Descartes and the Newtonians. But Leibniz also complains that Burnet misconceives the boundary between natural explanation and reflections on divine wisdom. And Leibniz's essays on cyclical cosmology suggest the alternative to Burnet's account: a natural history of the earth and its inhabitants should be radically autonomous from, even if ultimately harmonious with, theological principles.

In contemporary metaphysics, the Eleatic Principle (EP) is a causal criterion for reality. Articulating the EP with precision is notoriously difficult. The criterion purportedly originates in Plato’s Sophist, when the Eleatic Visitor articulates the EP at 247d-e in the famous Battle of the Gods and the Giants. There, the Visitor proposes modifying the ontologies of both the Giants (who are materialists) and the Gods (who are friends of the many forms), using a version of the EP according to which (...) only items which have the capacity to affect or to be affected are real. Recently, it has been argued that while there are some genetic connections between the EP and the views of some of the historical Eleatics (Parmenides and Zeno), the views of Melissus are generally incompatible with the EP. This raises the following question: What, exactly, is Eleatic about the Eleatic Principle? In this paper, I look to the dialectical context in which the Visitor’s appeal to the EP appears, and I propose that there are at once three relevant senses of affecting and being affected in the text: (1) tangible contact (as in the interactions between the bodies of the materialists), (2) Cambridge change (as in the form's being affected by a soul via the act of coming to know), and (3) the notion of a cause that does not itself change (as in a form’s affecting another form, a soul, or any sensible item). I argue that these have clear parallels to the metaphysics of all three main Eleatic philosophers, and that the views of Parmenides, Zeno, and Melissus are therefore compatible with the EP. This has interesting consequences for narratives about the reception of the Eleatics in Plato, the inclusion of an Eleatic Visitor as an interlocutor in the Sophist, and for the metaphysics of subsequent schools (such as the Stoics) who are widely thought to have been influenced by the EP.

In ancient philosophy, there is no discipline called “logic” in the contemporary sense of “the study of formally valid arguments.” Rather, once a subfield of philosophy comes to be called “logic,” namely in Hellenistic philosophy, the field includes (among other things) epistemology, normative epistemology, philosophy of language, the theory of truth, and what we call logic today. This entry aims to examine ancient theorizing that makes contact with the contemporary conception. Thus, we will here emphasize the theories of the “syllogism” (...) in the Aristotelian and Stoic traditions. However, because the context in which these theories were developed and discussed were deeply epistemological in nature, we will also include references to the areas of epistemological theorizing that bear directly on theories of the syllogism, particularly concerning “demonstration.” Similarly, we will include literature that discusses the principles governing logic and the components that make up arguments, which are topics that might now fall under the headings of philosophy of logic or non-classical logic. This includes discussions of problems and paradoxes that connect to contemporary logic and which historically spurred developments of logical method. For example, there is great interest among ancient philosophers in the question of whether all statements have truth-values. Relevant themes here include future contingents, paradoxes of vagueness, and semantic paradoxes like the liar. We also include discussion of the paradoxes of the infinite for similar reasons, since solutions have introduced sophisticated tools of logical analysis and there are a range of related, modern philosophical concerns about the application of some logical principles in infinite domains. Our criterion excludes, however, many of the themes that Hellenistic philosophers consider part of logic, in particular, it excludes epistemology and metaphysical questions about truth. Ancient philosophers do not write treatises “On Logic,” where the topic would be what today counts as logic. Instead, arguments and theories that count as “logic” by our criterion are found in a wide range of texts. For the most part, our entry follows chronology, tracing ancient logic from its beginnings to Late Antiquity. However, some themes are discussed in several eras of ancient logic; ancient logicians engage closely with each other’s views. Accordingly, relevant publications address several authors and periods in conjunction. These contributions are listed in three thematic sections at the end of our entry. (shrink)

This paper looks at the history of the problem of individuation from Plato to Whitehead. Part I takes as its point of departure Reiner Wiehl’s interpretation of the different meanings of “abstract” in the metaphysics of Alfred North Whitehead and arrives at a corresponding taxonomy of different ways things can be called concrete. Part II compares the way philosophers in different periods understand the relation between thought and intuition. The view mostly associated with ancient philosophy is that thought and (...) sense-perception target different kinds of objects. The view mostly associated with modern philosophy (although it was introduced by the Stoics) is that thought and sense-perception are different ways of targeting the same objects. These differences have specific consequences for theories of individuation, which are assessed historically in Part III and then applied to Whitehead’s difficult texts in part IV. (shrink)

Baruch, or Benedictus, Spinoza (1632–77) is the author of works, especially the Ethics and the Theological-Political Treatise, that are a major source of the ideas of the European Enlightenment. The Ethics is a dense series of arguments on progressively narrower subjects – metaphysics, mind, the human affects, human bondage to passion, and human blessedness – presented in a geometrical order modeled on that of Euclid. In it, Spinoza begins by defending a metaphysics on which God is the only (...) substance and is bound by the laws of his own nature. Spinoza then builds a naturalistic ethics that is constrained by, and to some extent is a product of, his strong metaphysics. Human beings are individuals that causally interact with other individuals and are extremely vulnerable to external influence. They are not substances. Moreover, human beings are bound by the same laws that bind all other individuals in nature, so Spinoza presents accounts of goodness, virtue, and perfection that are consistent with these perfectly general laws. Spinoza’s principal influences include René Descartes, Thomas Hobbes (see hobbes, thomas), Moses Maimonides (see maimonides, moses), the Roman Stoics (see stoicism), and Aristotle (see aristotle). Although his innovative philosophical views undoubtedly contributed to the strong writ of cherem, or ostracism, that Spinoza received from the Portuguese Jewish community of Amsterdam in 1656, his work nevertheless also shows the influence of the study of Scripture and of Jewish law.

El presente trabajo se concentra en el debate acerca de los alcances de la providencia que tuvo lugar entre las escuelas estoica, platónica y peripatética entre las siglos I y III de nuestra era. En ese contexto, analiza el problema del status ontológico de los singulares en Orígenes de Alejandría y Nemesio de Émesa. Influidos primariamente por la síntesis filoniana entre las distintas teorías griegas de providencia y la de las Escrituras, estos autores fundan la consistencia de los singulares en (...) la tesis de una acción directa del principio divino sobre cada uno de ellos. Frente a una cierta tendencia universalista y necesitarista del pensamiento clásico, los Padres griegos intentaron rescatar el valor metafísico del individuo en cuanto tal. -/- The present paper focuses on the debate over the scope of Providence that took place among the Stoic, Platonic and Peripatetic schools between the first and the third centuries AD. In that context, it deals with the problem of the ontological status of the singulars in the thought of Origen of Alexandria and Nemesius of Emesa. Influenced primarily by the Philonian synthesis of the different Greek theories of Providence with that of the Scriptures, Origen and Nemesius ground the consistency of individual beings on the thesis of a direct divine action intended for each of them. Faced with the universalistic and necessitarian tendencies of classical thought, the Greek Fathers tried to rescue the metaphysical value of individuals as such. (shrink)

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.

The paper presents the notion of “Spirit of Nature” in Henry More and describes its position within More’s philosophical system. Through a thorough analysis, it tries to show in what respects it can be considered a scientific object and in what respects it cannot. In the second part of this paper, More’s “Spirit of Nature” is compared to Newton’s various attempts at presenting a metaphysical cause of the force of gravity, using the similarities between the two to see this notorious (...) problem of Newton scholarship in a new light. One thus sees that if Newton drew from Stoic and Neo-Platonic theories of aether or soul of the world, we need to fully acknowledge the fact that these substances were traditionally of a non-dualistic, half-corporeal, half-spiritual nature. Both More’s “Spirit of Nature” and Newton’s aether can thus be understood as different attempts at incorporating such a pneumatic theory into the framework of modern physics, as it was then being formed.

Although Descartes’ characterization of the mind has sometimes been seen as too ‘moral’ and too ‘intellectualist’ to serve as a modern notion of consciousness, this article re-establishes the idea that Descartes’ way of doing metaphysics contributed to a novel delineation of the sphere of the mental. Earlier traditions in moral philosophy and religion certainly emphasized both a dualism of mind and body and a contrast between free intellectual activities and forcibly induced passions. Recent scholastic and neo-Stoic philosophical traditions, (...) moreover, drew attention to the disparity between the material and the immaterial, as well as to the possibility of a retreat into the personal realm of one’s own mind. Yet none of these moral and religious assessments of the relation between mind and body were motivated by the purely epistemological interest that we find in Descartes in setting apart a world of consciousness from the world of physics. The present article explains how Descartes made use of specific theological and moral philosophical theories in his own analysis of mental faculties; how he changed the orientation of metaphysics itself in the direction of a phenomenology of the mental; how he never returned to the naive idea of offering a dualist foundation for ethics; and how his mechanicism may have motivated his epistemological transformation of the science of metaphysics. In all these various ways, Descartes inaugurated an understanding of human mental life on the basis of physiological rather than metaphysical considerations, a view of psychology that is related to the experience of human individuals, and a naturalistic characterization of the mind in terms of a domain of consciousness rather than of moral conscience.

We are going to present a panorama of Byzantine Philosophy. As starting point should be considered the Patristic Thought, which preceded the Byzantine Philosophy and was established in the first centuries A.D. into the Greek-Roman world. It was based on the Old and New Testament, the apostolic teachings, as well as on Judaism and Greek Philosophy. Also, the Ancient Oriental Religions – especially those of the Greek-Roman period, i.e. the Gnosticism- exerted an influence on it. The Patristic Thought and the (...) Ancient Greek Philosophy were the two main pedestals of Byzantine Philosophy. But, we cannot separate completely Patristic thought from the Byzantine Philosophy, first because the Byzantine Philosophy used all the corpus of the preceded texts of the Church Fathers and second because the Patristic Thought was continued to the end of Byzantium in interaction with Byzantine Philosophy. When we use he term Byzantine Philosophy we refer to the ideological currents that flourished from the 9th century till the 15th in the geographical area of the Greek East. Its main task was the quest for truth from the metaphysical point of view. In this era we have not only commentaries and scholastic works, but also an assimilation of the previous philosophical and scientific developments in purpose of an interior evolution. The opposition to, and the use of, the Western scholasticism were also another two special characteristics of Byzantine Thought. The use of the logical works of Aristotle and the metaphysics of Plato made up its main theoretical body, always in relation to the Christian dogmas. The logical, metaphysical, cosmological, ethical, aesthetical and anthropological subjects were closely connected with the fixed Christian view of the World, God and Man. But despite the influence of the Christian religion and the Aristotelic, Platonic, Stoic, Neoplatonic etc. teachings, today we can arrive at the conclusion that from the ninth through the fifteen century a relative autonomy of Philosophy in Byzantium was emerged. Also, the Philosophical thought in Byzantium gave some new solutions to the old problems and dared sometimes to proceed in new rational, mystical or even empirical elaborations of original philosophical questions.

I argue that current projects in ‘naturalized metaphysics’ fail to be properly naturalistic, and thereby fail in their stated aim to take one’s metaphysics from science. I argue that naturalism must involve the idea of taking science seriously, and that this can only be spelled out in terms of taking not only the theories of science seriously, but also its practice and its socio-linguistic situatedness seriously as well. This accords with naturalism because not doing so draws an artificial (...) (non-natural) distinction between the epistemic products of science as essence, and its socio-linguistic and practical features as accidents. The picture of naturalism which falls out of this is a form of pragmatism. Once this is spelled out, the question becomes, what is the appropriate attitude for the pragmatist/naturalist to have toward ontology? It is not the same as that of traditional metaphysics, since such an attitude (that metaphysical theorizing can make positive epistemic contributions) requires a priori commitments which themselves are (1) not subject to empirical review, and (2) are anthropocentric and so potentially distorted. But the pragmatist/naturalist will not go the opposite way, and say that metaphysics is meaningless either, since (true to their pragmatic commitments) ontology does things for the scientist and the layperson. It is a mistake to reject it wholesale, since the task of asserting what there is, exposing such an ontology to criticism, both empirical and logical, and revising it, has both small-scale and large-scale consequences. On the small-scale, ontologies are a guide for thinking—scientists, engineers, and lay people can and do use models of existence to navigate occurent problems in their day-to-day lives. Whether this is posing research hypotheses, developing protocols for generating new materials, or cooling off a cup of coffee, ontology plays a role. Large-scale consequences are more weighty, and more difficult to see. These large-scale consequences have to do with the aims and values which individuals and societies possess, and their interrelation with ontology. This certainly was at the forefront of the earliest ontologies—the Epicureans and Stoics built their moral philosophy on the basis of what ontology they thought was correct. This sort of practice goes on, unabated, today, though with virtually no overt acknowledgement of this important interdependency. How, for the pragmatist, do we make sense of ontological talk, if we are to eschew traditional metaphysics? Ontology—the naturalist/pragmatist declares—is a tool. Ontology helps us do things, whether it be predict behavior, understand phenomena, blame or forgive someone, and hope or despair about a life after this one (for example). Building an ontology is about building our own concepts, and this, in turn is a negotiation between our beliefs, experiences, and commitments, and the beliefs, experiences, and commitments of with whom we’re discursively engaged.

This paper is concerned with the paradox of decrease. Its aim is to defend the answer to this puzzle that was propounded by its originator, namely, the Stoic philosopher Chrysippus. The main trouble with this answer to the paradox is that it has the seemingly problematic implication that a material thing could perish due merely to extrinsic change. It follows that in order to defend Chrysippus’ answer to the paradox, one has to explain how it could be that Theon (...) is destroyed by the amputation without changing intrinsically. In this paper, I shall answer this challenge by appealing to the broadly Aristotelian idea that at least some of the proper parts of a material substance are ontologically dependent on that substance. I will also appeal to this idea in order to offer a new solution to the structurally similar paradox of increase. In this way, we will end up with a unified solution to two structurally similar paradoxes. (shrink)

This paper looks at Gregory of Nyssa's so-called "bundle theory" sensible individuals and matter (as recently argued by Gerd Van Riel and Thomas Wauters in a 2020 article) amidst the broader context of Gregory's view of created beings and his reception of Neoplatonist, Stoic, and Aristotelian conceptions of particulars and matter. I argue that Gregory's position is closer to an Aristotelian position, despite the parallels to Plotinus and other contemporaneous bundle theory positions: in arguing against prime matter, and insofar (...) as he emphasizes the identity of each kind of created being with its material substrate—understood as a "bundle" of properties—Gregory inadvertently upholds a reading of Aristotle that refutes an ontological notion of prime matter.

‘Sapiens and Sthitaprajna’ studies the concept of a wise person in the Stoic Seneca and in the Bhagavad-Gita. Although the Gita and Seneca’s writings were composed at least two centuries and a continent apart, they have much in common in recommending a well lived life. This book describes how in both - a wise person is endowed with both virtue and wisdom, is moral, makes right judgments and takes responsibility for actions. A wise and virtuous person always enjoys happiness, (...) as happiness consists in knowing that one has done the right thing at the right time. Both Seneca and the Gita demand intellectual rigor and wisdom for leading a virtuous and effective life. They provide guidelines for how to become and be wise. Both systems demand a sage to be emotionally sound and devoid of passions. This leads to mental peace and balance, and ultimately tranquility and happiness. While surveying these similarities, this study also finds differences in their ways of application of these ideas. The metaphysics of the Gita obliges the sage to practice meditation, while the Stoics require a sage to be a rational person committed to analyzing and intellectualizing any situation. This comparative study will be of interest to students of both Ancient Western and Ancient Indian Philosophy. Practitioners of Stoicism and followers of the Gita should find the presence of closely related ideas in a very different tradition of interest while perhaps finding somewhat different prescriptions a spur to action.

"CONSOLATIONE PHILOSOPHIAE" BY SEVERIN BOETHIUS The paper examines the literature basic of Severin Boethius work «The Consolation of Philosophy». The author starts with the historical context of the appearance of the text and then goes to consider its variety of literary genres and forms. Main of them are satura Menippea, consolation, protreptic, soliloquy, and dialogue. Textual and conceptual analyses have relieved the connection between Boethius’s «The Consolation» and the works of other famous authors of Antiquity among them there are Plato, (...) Aristotle, Seneca, Cicero, and St. Augustine. As a connoisseur of Antiquity, Boethius uses literature to explain his philosophical ideas. In addition, the author of the article suggests an analytical review of the image of the Lade Philosophy in «Consolation». The genealogy of this literary character refers to the Greek mythology, Plato’s «Symposium» and «Crito» dialogues, Martianus Capella’s work «On the Marriage of Philology and Mercury» and Augustine’s the literary image of St. Monika. The article reconstructs an epistemological methodology of Boethius’s Neoplatonic dialogue that consists of five stages and describes a therapeutic role of philosophy in the traditions of Plato and Stoics. The essence of this role is a mind therapy. Philosophy teaches us to see the world as a whole, to describe it in clear notions and judgments. According to the text of «Consolation», Boethius takes us to make an intellectual Neoplatonic climbing from practical (ethic) to theoretical (metaphysic) philosophy – from vita activa to vita speculativa. The main aim or the top of this Neoplatonic meditation is a contemplative life or reminding own Ego. The great ideas of this work have the significant influence on Medieval andRenaissance philosophy and literature. Keywords: Lady Philosophy, Neoplatonic. (shrink)

In this paper we examine the genealogy and transmission of moral duty in Western ethics. We begin with an uncontroversial account of the Stoic notion of the kathēkon, and then examine the pivotal moment of Cicero’s translation of it into Latin as ‘officium’. We take a deflationary view of the impact of Cicero’s translation and conclude that his translation does not mark a departure from the Stoic ideal. We find further confirmation of our deflationary position in the development (...) of the notion of ‘duty’ in Germany between the 16th and 18th centuries. We examine Pufendorf’s critique of ancient eudaimonism and his appropriation of officium, and claim that it foreshadows Kant’s rejection of Garve’s Ciceronian ethics. We demonstrate the undeniable parallels between Kant’s Groundwork and Garve’s influential translation of Cicero’s De Officiis, thereby indicating a novel way in which we should understand Cicero’s contribution to the development of modern moral philosophy.

One Stoic response to the skeptical indistinguishability argument is that it fails to account for expertise: the Stoics allow that while two similar objects create indistinguishable appearances in the amateur, this is not true of the expert, whose appearances succeed in discriminating the pair. This paper re-examines the motivations for this Stoic response, and argues that it reveals the Stoic claim that, in generating a kataleptic appearance, the perceiver’s mind is active, insofar as it applies concepts matching (...) the perceptual stimulus. I argue that this claim is reflected in the Stoic definition of the kataleptic appearance, and that it respects their more general account of mental representation. I further suggest that, in attributing some activity to the mind in creating each kataleptic appearance, and in claiming that the expert’s mind allows her to form more kataleptic appearances than the amateur, the Stoics draw inspiration from the wax tablet model in Plato’s Theaetetus (190e–196d), where Socrates distinguishes the wise from the ignorant on the basis of how well they match sensory input with its appropriate mental ‘seal’ (σφραγίς).

This chapter investigates the Stoic understanding of impressions, assent, opinion, scientific knowledge, and cognition. By analyzing these concepts, I describe one major difference between the wise Stoic sage and unwise people: the wise person is capable of scientific knowledge and strong assent, while the rest of us are not. I will also interpret the Stoic account of the cognitive impression and describe several ways that the student of Stoicism might make epistemic progress.

This paper explores the Persistence Question about cities, that is, what is necessary and sufficient for two cities existing at different times to be numerically identical. We first show that we can possibly put an end to the existence of a city in a number of ways other than by physically destroying it, which reveals the metaphysics of cities to be partly different from that of ordinary objects. Then we focus in particular on the commonly perceived vulnerability of cities (...) to imaginary relocation; and we make the hypothesis that cities do have among their essential properties that of being surrounded by a specific geographical context. Finally we investigate the pos- sibility that a city can survive relocation in virtue of the capacity of its geographical context to survive it in the first place. We suggest that city contexts may not be essentially context-dependent in turn, and outline a possible description of the cri- teria for their persistence over time. (shrink)

We argue that the extant evidence for Stoic logic provides all the elements required for a variable-free theory of multiple generality, including a number of remarkably modern features that straddle logic and semantics, such as the understanding of one- and two-place predicates as functions, the canonical formulation of universals as quantified conditionals, a straightforward relation between elements of propositional and first-order logic, and the roles of anaphora and rigid order in the regimented sentences that express multiply general propositions. We (...) consider and reinterpret some ancient texts that have been neglected in the context of Stoic universal and existential propositions and offer new explanations of some puzzling features in Stoic logic. Our results confirm that Stoic logic surpasses Aristotle’s with regard to multiple generality, and are a reminder that focusing on multiple generality through the lens of Frege-inspired variable-binding quantifier theory may hamper our understanding and appreciation of pre-Fregean theories of multiple generality.

This paper contends that Stoic logic (i.e. Stoic analysis) deserves more attention from contemporary logicians. It sets out how, compared with contemporary propositional calculi, Stoic analysis is closest to methods of backward proof search for Gentzen-inspired substructural sequent logics, as they have been developed in logic programming and structural proof theory, and produces its proof search calculus in tree form. It shows how multiple similarities to Gentzen sequent systems combine with intriguing dissimilarities that may enrich contemporary discussion. (...) Much of Stoic logic appears surprisingly modern: a recursively formulated syntax with some truth-functional propositional operators; analogues to cut rules, axiom schemata and Gentzen’s negation-introduction rules; an implicit variable-sharing principle and deliberate rejection of Thinning and avoidance of paradoxes of implication. These latter features mark the system out as a relevance logic, where the absence of duals for its left and right introduction rules puts it in the vicinity of McCall’s connexive logic. Methodologically, the choice of meticulously formulated meta-logical rules in lieu of axiom and inference schemata absorbs some structural rules and results in an economical, precise and elegant system that values decidability over completeness.

An overview of the ancient philosophers and their philosophical system (divided into the fields of logic, physics, and ethics) comprising the living, organic, enduring, and evolving body of interrelated ideas identifiable as the Stoic perspective.

Overview of the Stoic position. Looks at the roots of their determinism in their theology, their response to the 'lazy argument' that believing that all things are fated makes action pointless, their analysis of human action and how it allows actions to be 'up to us,' their rejection of the Principle of Alternate Possibilities, their rejection of anger and other negative reactive attitudes, and their contention that submission to god's will brings true freedom.

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)

This paper proposes a panpsychist interpretation of Anne Conway’s (1631-1679) metaphysics, as elucidated in 'The Principles of the Most Ancient and Modern Philosophy.' Contemporary versions of panpsychism attempt to explain how consciousness is realised in the natural world. They posit that matter is intrinsically experiential, such that when it is arranged into the form of a human brain, it gives rise to human consciousness. Similarly, Conway argues that substance is constituted by both Body and Spirit. The former serves as (...) an explanation of a substance’s material properties, whereas the latter explains how a substance can have various kinds of perceptual experiences, as well as experiencing sensation and emotion. I argue that Conway uses her concept of Spirit to refer to the same set of experiential properties as our contemporary concept of consciousness does. Understood thus, Conway’s metaphysical framework appears to embrace a form of panpsychism. (shrink)

ABSTRACT: For the Stoics, a syllogism is a formally valid argument; the primary function of their syllogistic is to establish such formal validity. Stoic syllogistic is a system of formal logic that relies on two types of argumental rules: (i) 5 rules (the accounts of the indemonstrables) which determine whether any given argument is an indemonstrable argument, i.e. an elementary syllogism the validity of which is not in need of further demonstration; (ii) one unary and three binary argumental rules (...) which establish the formal validity of non-indemonstrable arguments by analysing them in one or more steps into one or more indemonstrable arguments (cut type rules and antilogism). The function of these rules is to reduce given non-indemonstrable arguments to indemonstrable syllogisms. Moreover, the Stoic method of deduction differs from standard modern ones in that the direction is reversed (similar to tableau methods). The Stoic system may hence be called an argumental reductive system of deduction. In this paper, a reconstruction of this system of logic is presented, and similarities to relevance logic are pointed out. (shrink)

This essay considers how ancient Stoic cosmopolitanism – roughly, the claim all human beings are members of the same “cosmopolis”, or universal city, and so are entitled to moral concern in virtue of possessing reason – informs Stoic thinking about how we ought to treat non-human entities in the environment. First, I will present the Stoic justification for the thesis that there are only rational members of the cosmopolis – and so that moral concern does not extend (...) to any non-human part of the natural world – and explore the foundations of these views in Stoic physics. Next, I will show that, like other anthropocentric theories, Stoic cosmopolitanism allows for environmental preservation and protection of non-human entities, so long as these activities ultimately benefit human beings. However, because the Stoics include the appreciation of natural beauty as a component of the happy life, this justification is not as feeble as it might seem. Humans are naturally set up to contemplate the order and complexity of the universe, and so environmental degradation and species loss, in marring this harmonious system, frustrates the achievement of the human goal. After exploring these facets of Stoic philosophy, and assessing to what extent they might justify environmental conservation, I close with a critical appraisal of Stoic theory – specifically, of the claims that (i) only humans possess reason and (ii) only rational creatures are deserving of moral concern.

ABSTRACT: In contemporary discussions of freedom in Stoic philosophy we often encounter the following assumptions: (i) the Stoics discussed the problem of free will and determinis; (ii) since in Stoic philosophy freedom of the will is in the end just an illusion, the Stoics took the freedom of the sage as a substitute for it and as the only true freedom; (iii) in the c. 500 years of live Stoic philosophical debate, the Stoics were largely concerned with (...) the same philosophical problems of freedom. In this paper I argue that (i) can be upheld only in a very restricted way; (ii) is altogether untenable; and regarding (iii), that, although there may have occurred little change in the Stoic philosophical position on freedom over the centuries, we can detect more than one transformation of the philosophical problems that were at the forefront of the discussion. Moreover, that all the conceptions and problems of freedom were linked to Stoic ethics, and that the differences between them become transparent when one considers their various roles in this context.

Scientific realism is typically associated with metaphysics. One current incarnation of such an association concerns the requirement of a metaphysical characterization of the entities one is being a realist about. This is sometimes called “Chakravartty’s Challenge”, and codifies the claim that without a metaphysical characterization, one does not have a clear picture of the realistic commitments one is engaged with. The required connection between metaphysics and science naturally raises the question of whether such a demand is appropriately fulfilled, (...) and how metaphysics engages with science in order to produce what is called “scientific metaphysics”. Here, we map some of the options available in the literature, generating a conceptual spectrum according to how each view approximates science and metaphysics. This is done with the purpose of enlightening the current debate on the possibility of epistemic warrant that science could grant to such a metaphysics, and how different positions differently address the thorny issue concerning such a warrant.

When it comes to the discussions of ancient economic thought, the Stoics rarely come to the forefront. By and large, the lack of focus on this Hellenistic philosophical school is understandable: there is no evidence of the Stoics writing treatises entitled oikonomikos or similar or, in fact, showing any substantial interest in the matters pertaining to wealth management or money acquisition. There is an extant fragment, however, depicting a debate between Diogenes of Babylon and Antipater of Tarsus in which the (...) latter advocates for the moral permissibility of the behaviour that comes very close to exhibiting economic rationality. In this paper, I analyse this passage and, noting its complex transmission history, I argue that it reveals an engagement with various ideas pertaining to the oikonomia genre. Although some of them resemble the contemporary notion of economic rationality, ultimately, the Stoic argument is embedded in ethical debates with the Peripatetics and it concerns moral value rather than the homo economicus style of reasoning about maximizing gains.

This paper examines the Stoic account of apprehension (κατάληψις) (a cognitive achievement similar to how we typically view knowledge). Following a seminal article by Michael Frede (1983), it is widely thought that the Stoics maintained a purely externalist causal account of apprehension wherein one may apprehend only if one stands in an appropriate causal relation to the object apprehended. An important but unanswered challenge to this view has been offered by David Sedley (2002) who offers reasons to suppose that (...) the Stoics (or at least Zeno, the founder of the Stoa) did not make such a causal stipulation. I offer a defence of the traditional, causal reading against the challenges raised by Sedley but also argue, against the traditional view, that the Stoic account incorporated an internalist element. On the hybrid account defended here, in order to apprehend not only must the agent stand in an appropriate causal relation to the object apprehended but the agent’s appearance of the object must also be clear (a feature which is accessible to the epistemic agent). The traditional scholarly view rejects internalist interpretations because it is thought that such interpretations cannot make sense of the Stoics’ discussion of the ‘automatic assent’ produced by kataleptic appearances and a purely externalist view is taken to be charitable insofar as it saves the Stoics from a vicious regress which they would otherwise face (were they internalists). I spell out how the regress might be taken to function and defend an internalist interpretation against both these charges. The internalist element embraced by the Stoics does not lead to the problems it is often thought to and the account defended here not only does justice to the textual evidence but also sheds light on the Stoic debates with their sceptical opponents and grants the Stoics an epistemic account fit for purpose.

ABSTRACT: This paper discusses the Stoic treatment of fallacies that are based on lexical ambiguities. It provides a detailed analysis of the relevant passages, lays bare textual and interpretative difficulties, explores what the Stoic view on the matter implies for their theory of language, and compares their view with Aristotle’s. In the paper I aim to show that, for the Stoics, fallacies of ambiguity are complexes of propositions and sentences and thus straddle the realms of meaning (which is (...) the domain of logic) and of linguistic expressions (which is the domain of linguistics), but also involve a pragmatic element; that the Stoics believe that the premises of the fallacies, when uttered, have only one meaning and are true, and thus should be conceded; that hence there is no need for a mental process of disambiguation in the listeners; that Aristotle, by contrast, appears to assume that the premises always have all their meanings, and accordingly recommends that the listeners explicitly disambiguate them, which presupposes a process of mental disambiguation. I proffer two readings of the Stoic advice that we ‘be silent’ when confronted with a fallacy of ambiguity in dialectical discourse, and explicate how each leads to an overall consistent interpretation of the textual evidence. Finally, I demonstrate that the method advocated by the Stoics works in all cases of fallacies of lexical ambiguity. (shrink)

Transient Truths: An Essay in the Metaphysics of Propositions provides the first book-length exposition and defense of semantic temporalism, the view that propositions are contents or semantic values that can change their truth-values across time.

ABSTRACT: In this paper I argue (i) that the hypothetical arguments about which the Stoic Chrysippus wrote numerous books (DL 7.196) are not to be confused with the so-called hypothetical syllogisms" but are the same hypothetical arguments as those mentioned five times in Epictetus (e.g. Diss. 1.25.11-12); and (ii) that these hypothetical arguments are formed by replacing in a non-hypothetical argument one (or more) of the premisses by a Stoic "hypothesis" or supposition. Such "hypotheses" or suppositions differ from (...) propositions in that they have a specific logical form and no truth-value. The reason for the introduction of a distinct class of hypothetical arguments can be found in the context of dialectical argumentation. The paper concludes with the discussion of some evidence for the use of Stoic hypothetical arguments in ancient texts. (shrink)

Chrysippus often talks as if there is a third option when we might expect that two options in response to a question are exhaustive. Things are true, false or neither; equal, unequal, or neither; the same, different, or neither.. and so on. There seems to be a general pattern here that calls for a general explanation. This paper offers a general explanation of this pattern, preserving Stoic commitments to excluded middle and bivalence, arguing that Chrysippus employs this trichotomy move (...) when he wishes to argue that apparent contradictories are only contraries, and wishes to endorse a third option. This general explanation of the pattern of trichotomies sheds light on a number of interpretive puzzles, including on Chrysippus's response to the paradox of the cone. The purpose of these trichotomies is also discussed, and it is suggested that they originate from the dialectical context in which philosophical problems were posed. (shrink)

Many who take a dismissive attitude towards metaphysics trace their view back to Carnap’s ‘Empiricism, Semantics and Ontology’. But the reason Carnap takes a dismissive attitude to metaphysics is a matter of controversy. I will argue that no reason is given in ‘Empiricism, Semantics and Ontology’, and this is because his reason for rejecting metaphysical debates was given in ‘Pseudo-Problems in Philosophy’. The argument there assumes verificationism, but I will argue that his argument survives the rejection of verificationism. (...) The root of his argument is the claim that metaphysical statements cannot be justified; the point is epistemic, not semantic. I will argue that this remains a powerful challenge to metaphysics that has yet to be adequately answered. (shrink)

This paper is a discussion of Gabriel, Hülser and Schlotter’s 2009 article on a possible causal relation between Stoic logic and Frege. The paper provides detailed argument for why Rudolf Hirzel should not be taken as the qualified middleman in philosophical discussion with whom Frege learned what he ‘borrowed’ without acknowledgement from Stoic logic. Additionally, this paper offers some modest findings about some aspects of Frege's and Hirzel's lives and work habits, which may help us understand a little (...) better Frege's connection to Hirzel and to Stoic logic as well as Frege’s failure to acknowledge the Stoics. This paper is a purely historical offshoot of my essay ‘Frege plagiarized the Stoics’. Zero direct insights into either Frege’s or Stoic philosophy are offered. OPEN ACCESS.

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.
