In Stoic physics, blending (κρᾶσις) is the relation between active pneuma and passive matter; natural bodies from rocks and logs to plants, animals and the cosmos itself are blends of pneuma and matter. Blending structures the Stoic cosmos. I develop a new interpretation of the Stoic theory of blending, based on passages from Hierocles. The theory of blending, I argue, has been misunderstood. Hierocles allows us to see in detail how the theory is supposed (...) to work and how it fits into Stoic physics. (shrink)

Despite the central importance of Alexander of Aphrodisias to later Greek, Medieval, and Renaissance philosophy, little attention has been given to his work in modern times. Only one of his writings, the De fato, has been available in English translation. Todd’s study and translation of Alexander’s De mixtione is therefore a welcome contribution. His book not only contributes to the study of Alexander but also presents a critical analysis of the evidence concerning the theory of the "total blending" of (...) bodies attributed to the Stoics by Alexander and by other ancient sources. By investigating the polemical character of such reports concerning Stoicism, Todd attempts to develop a means of evaluating the evidence, the consequence of which is a revision of not a few aspects of what has been thought to be Stoic doctrine.

Stoic physics, based entirely on the continuum concept, is one of the great original contributions in the history of physical systems. Building on The Physical World of the Greeks, the author describes the main aspects of the Stoic continuum theory, traces its origins back to pre-Stoic science and philosophy, and shows the attempts of the Stoics to work out a coherent system of thought that would explain the essential phenomena of the physical world by a few (...) basic assumptions.

ABSTRACT: A systematic reconstruction of Chrysippus’ theory of causes, grounded on the Stoic tenets that causes are bodies, that they are relative, and that all causation can ultimately be traced back to the one ‘active principle’ which pervades all things. I argue that Chrysippus neither developed a finished taxonomy of causes, nor intended to do so, and that he did not have a set of technical terms for mutually exclusive classes of causes. Rather, the various adjectives which he (...) used for causes had the function of describing or explaining particular features of certain causes in particular philosophical contexts. I challenge the sometimes assumed close connection of Chrysippus’ notion of causation with explanation. I show that the standard view that the distinction between proximate and auxiliary causes and perfect and principal causes corresponds to the distinction between internal and external determining factors is not born out by the evidence, and argue that causes of the two types were not thought to co-operate, but rather conceived of as alternatives.

According to the ancient Greek Stoics, the cosmos regularly transitions between periods of conflagration, during which only fire exists, and periods of cosmic order, during which the four elements exist. This paper examines the cosmogonic process by which conflagrations are extinguished and cosmic orders are restored, and it defends three main conclusions. First, I argue that not all the conflagration’s fire is extinguished during the cosmogony, against recent arguments by Ricardo Salles. Second, at least with respect to the cosmogony, it (...) is not necessary to posit the existence of proto-elements. Third, while scholars such as Salles and David Hahm have argued that Cleanthes held a distinct theory of cosmogony from Zeno and Chrysippus, I argue that each of these Stoics endorse the same cosmogonic theory.

The aim of this paper is to explore how the cosmic soul works and how it accomplishes its providential and demiurgic tasks in Chrysippus’ system. Drawing on (i) the analogy Chrysippus establishes between the individuum and the cosmos and (ii) biological and medical theories of respiration, digestion, and pulse, I will show that the movements of Chrysippus’ cosmic soul reproduce the processes of digestion, pulse, and respiration at a cosmic level. My claim is that Chrysippus, in addition to adopting Praxagoras’ (...) notion that inhaled air nourishes pneuma—well established in the scholarship—appropriated Aristotle’s complex mechanism of respiration and digestion based on the teleological role of cold air, crucial for preserving vital heat. So understood, Chrysippus’ application of biological notions to cosmology allows him to endow the active principle with effective causation throughout the cosmos. (shrink)

In this paper, it is argued the Stoics develop an account of corporeals that allows their theory of bodies to be, at the same time, a theory of causation, agency, and reason. The paper aims to shed new light on the Stoics' engagement with Plato's Sophist . It is argued that the Stoics are Sons of the Earth insofar as, for them, the study of corporeals - rather than the study of being - is the most fundamental study (...) of reality. However, they are sophisticated Sons of the Earth by developing a complex notion of corporeals. A crucial component of this account is that ordinary bodies are individuated by the way in which the corporeal god pervades them. The corporeal god is the one cause of all movements and actions in the universe. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Spinoza and the Theory of Organism HANS JONAS I CARTESIANDUALISMlanded speculation on the nature of life in an impasse: intelligible as, on principles of mechanics, the correlation of structure and function became within the res extensa, that of structure-plus-function with feeling or experience (modes of the res cogitans) was lost in the bifurcation, and thereby the fact of life itself became unintelligible at the same time that the (...) explanation of its bodily performance seemed to be assured. The impasse became manifest in Occasionalism : its tour de force of an extraneous, divine "synchronization" of the outer and the inner world (the latter denied to animals) not only suffered from its extreme artificiality, the common failing of such ad hoc constructions, but even at so high a cost failed to accomplish its theoretical purpose by its own terms. For the animal machine, like any machine, raises beyond the question of the "how" that of the "what for" of its functioning---of the purpose for which it had thus been constructed by its maker.1 Its performance, however devoid of immanent teleology, must serve an end, and that end must be someone's end. This end may (directly) be itself, as indeed Descartes had implied when declaring self-preservation to be the effect of the functioning of the organic automaton. In that case the existence as such of the machine would be its end--either terminally, or in turn to benefit something else. In the former case, the machine would have to be more than a machine, for a mere machine cannot enioy its existence. But since, by the rigorous conception of the res extensa, it cannot be more than a machine, its function and/or existence must serve something other than itself. Automata in Descartes ' time were mainly for entertainment (rather than work). But the raison d'etre of the living kingdom could not well be seen in God's indulging his mechanical abilities or in the amusement of celestial spectators--especially since mere complexity of arrangement does not create new quality and thus add something to the unrelieved sameness of the simple substratum that might enrich the spectrum of being. For quality, beyond the primitive determinations of the extended per se, is the subjective creature of sensation, the confused representation of quantity in a mind; and thus organisms cannot harbor it because as mere machines they lack mentality, and pure spirits cannot because they lack sensuality, or the privilege of confusion and thereby of illusion with its possible enjoyment. And as to their intellectual enjoyment, even that, deprived of the thrill of discovery by the same token, would pale in the contemplation of what to sufficiently large The concept of "machine," adopted for its strict confinementto efficientcause, is still a finalisticconcept,even thoughthe final cause is no longer internal to the entity, as a mode of its own operation,but external to it as antecedent design. [43] 44 HISTORY OF PHILOSOPHY intellects is nothing but the ever-repeated exemplification of the same few, elementary (and ultimately trivial) truths. There remained, then, the time-honored--Stoic as well as Christian--idea that plants and animals are for the benefit of Man. Indeed, since the existence of a living world is the necessary condition for the existence of any of its members, the self-justifying nature of at least one such member (= species) would justify the existence of the whole. In Stoicism, Man provided this end by his possession of reason, which makes him the culmination of a terrestrial scale of being that is also self-justifying throughout all its grades (the end as the best of many that are good in degrees) ; in Christianity, by his possession of an immortal soul, which makes him the sole imago Dei in creation (the end as the sole issue at stake) ; and Cartesian dualism radicalized this latter position by making man even the sole possessor of inwardness or "soul" of any kind, thus the only one of whom "end" can meaningfully be predicated as he alone can entertain ends. All other life then, the product of physical necessity, can be considered his means. However, this traditional idea, in its anthropocentric vanity never a... (shrink)

This book presents a detailed analysis of three ancient models of spatial magnitude, time, and local motion. The Aristotelian model is presented as an application of the ancient, geometrically orthodox conception of extension to the physical world. The other two models, which represent departures from mathematical orthodoxy, are a "quantum" model of spatial magnitude, and a Stoic model, according to which limit entities such as points, edges, and surfaces do not exist in (physical) reality. The book is unique in (...) its discussion of these ancient models within the context of later philosophical, scientific, and mathematical developments. (shrink)

From the meagre fragments available, Sambursky has carefully reconstructed the basic physical concepts of the Stoa, emphasizing the continuum theory developed by Chrysippos and Poseidonios. Stoic physics, in contrast with Democritean atomism, has been largely neglected, in spite of its relevance to contemporary theories of continuity. Sambursky's contribution should overcome this omission to a great extent, and, together with Mates' and Lukasiewicz's work in Stoic logic, enable us to comprehend the non-ethical features of Stoic thought. Included (...) is a 30 page appendix giving English translations of the relevant classical fragments.--L. S. F. (shrink)

Nobody should have a monopoly of the truth in this universe. The censorship and suppression of challenging ideas against the tide of mainstream research, the blacklisting of scientists, for instance, is neither the best way to do and filter science, nor to promote progress in the human knowledge. The removal of good and novel ideas from the scientific stage is very detrimental to the pursuit of the truth. There are instances in which a mere unqualified belief can occasionally be converted (...) into a generally accepted scientific theory through the screening action of refereed literature and meetings planned by the scientific organizing committees and through the distribution of funds controlled by "club opinions". It leads to unitary paradigms and unitary thinking not necessarily associated to the unique truth. This is the topic of this book: to critically analyze the problems of the official mechanisms under which current science is being administered and filtered today, along with the onerous consequences these mechanisms have on all of us. The authors, all of them professional researchers, reveal a pessimistic view of the miseries of the actual system, while a glimmer of hope remains in the "leitmotiv" claim towards the freedom in doing research and attaining an acceptable level of ethics in science.

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.

This paper considers what function—if any—colocation of bodies may have in the Stoic theory of blending (κρᾶσις), by examining (1) whether colocation is part of the definition of what blending is; and (2) whether colocation is posited by the Stoics as a requirement necessary for the definition to be satisfied. I reconstruct the standard, Chrysippean definition of blending, and I show that the answer to (1) is ‘no’; further, I argue that the evidence gives no reason to affirm (...) (2). Thus, it appears that colocation does not have a central function in the Stoic theory of blending. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 42.1 (2004) 104-105 [Access article in PDF] William R. Newman and Lawrence M. Principe. Alchemy Tried in the Fire: Starkey, Boyle, and the Fate of Helmontian Chymistry. Chicago: University of Chicago Press, 2002. Pp. xv + 344. Cloth, $40.00. Newman and Principe have produced a masterful study of intellectual context, primarily by correcting the commonly held belief that there was a radical (...) break in the seventeenth century between late medieval alchemy and early modern chemistry. Although their main focus is on George Starkey (the 'alchemist') and Robert Boyle (the 'chemist'), they also provide copious details on the chemical practices and theories of Van Helmont, Benjamin Worsley, Frederick Clodius, and Kenelm Digby, among others. It is hard to do justice to their complex study in a short review. Following a brief summary, therefore, I will limit my discussion to how the authors' conclusions are significant for a more in-depth and nuanced understanding of philosophy in the seventeenth century.After a helpful introduction, Chapter 1 outlines the differences in the early lives of the English, aristocratic Boyle and the American, Harvard-educated Starkey. Chapter 2's background on late medieval chemistry includes an examination of corpuscular theories within that tradition as well as Van Helmont's arguments concerning the way in which mathematics is useful for explaining "superficial" changes but not the real, internal changes in bodies. Chapters 3 and 4 provide a close study of Starkey's laboratory notebooks. Among the entries, recorded in a style adapted from Scholasticism, there are passages that adopt the secrecy of alchemy, while others show Starkey's effective use of theoretical principles and such experimental quantitative methods as mass balance. Chapter 5 examines Boyle's intellectual context. Newman and Principe argue convincingly for Starkey's role in Boyle's addition of Helmontian elements to the general Baconian program. Chapter 6 looks at the [End Page 104] results of Boyle's eclectic mix of chemistry and mechanism. Although Helmontian chemistry played a significant role in Boyle's natural philosophy, the authors attribute his meager interest in quantitative measures and analyses to his attempts to use chemistry as a support for mechanism and as evidence against Aristotelianism. The concluding chapter draws together elements from previous chapters to provide the full argument against the idea of a radical break between medieval alchemy and modern chemistry.Newman and Principe's reconsideration of traditional categories surrounding the idea of a radical break should provide an impetus for similar reconsideration in the history of philosophy. As they point out, 'the' mechanical philosophy drew from a diverse range of disciplines. Boyle's eclectic and complex attempt to develop a unique version of the mechanical philosophy can be seen in other English philosophers, especially Locke and Newton. This study provides a promising basis for yet more extensive and refined studies of the seventeenth-century milieu. The continuing over-emphasis on the physical principles of Descartes and Gassendi's versions of the mechanical philosophy and the tendency to reduce all mechanism to their view needs revision. Also in need of reconsideration is the currently popular belief that the study of context simply means adding social elements to an uncontroversial intellectual context. As the authors clearly show, much more work on the intellectual context remains to be done.One line of research in the history of philosophy that could be pursued concerns the role of Francis Bacon in this context. Although Newman and Principe mention the general Baconian ethos, a detailed discussion of Bacon was clearly beyond their scope. Yet Bacon's own debts to chemistry, although frequently unrecognized, seem more significant given this study. Also, it would be interesting to see the extent to which Bacon's works influenced Van Helmont or Starkey. Newman and Principe's claims regarding the novelty of Starkey's notebooks, for example, may be a little overstated. Many of the elements from Starkey's notebooks can be found in Bacon's advice in his Natural and Experimental Histories (1622). In that work, Bacon advised writers... (shrink)

Everything is Something is a book about Stoic metaphysics. It argues that the Stoics are best understood as forging a bold new path between materialism and idealism, a path best characterized as non-reductive physicalism. To be sure, only individual bodies exist for the Stoics, but not everything there is exists — some things are said to subsist. However, this is no Meinongian move beyond existence, to the philosophy of intentionality (as the language of subsistence might suggest), but a one-world (...) metaphysics that both counts its entities by logical criteria, and grounds them in body by physical principles, yielding a tightly ordered ontology in which everything is Something and nothing is not. -/- This last phrase is not innocent. It invokes the Stoic innovation of Something (ti) as the highest genus of reality, and takes the stand that it is not only principled and coherent, but comprehensive — anything that is not Something is nothing at all (for the initiated: there is no class of Not-Somethings between Something and nothing). Further, everything that is Something is either itself a body, or ontologically dependent on body. Herein lies the Stoics’ non-reductive physicalism, and the beating heart of their response to the Battle of Gods and Giants in Plato’s Sophist: a one-world metaphysics. -/- The foundation of Stoic metaphysics is their ground-breaking corporealism, which introduces an alternative to both atomism and hylomorphism. The Stoics are continuum physicists for whom body as such, i.e. solid, three-dimensional extension, is homogeneous, partless, uniform, and infinitely divisible without reaching minima (atoms). And because body is not conceived along hylomorphic lines, i.e. as a composite of matter and form, the Stoics are free to make body fundamental. Out of two basic bodies, then (the archai), and by the tantalizing mechanism of through and through blending (krasis di’ holou), Stoic physics constructs the cosmos (and every body it contains) in completely corporealist terms, composing one thing out of many. And once those bodies are built, Stoic logic gives an account of their identity conditions, kinds, and qualities according to the vexed schema of the Categories, making now many out of one by the constitution relation, as a statue is constituted by its clay. With these distinct mereological relations of composition and constitution, Stoic corporealism artfully divides the labor of Plato’s Forms between physics and logic. -/- Next in the ontological order, with bodies as their foundation, are the incorporeals (asōmata): space (place, room, and surface), time, void, and the (awkwardly named) sayables, or lekta (roughly, though controversially, the meanings of our words). These entities do not exist; they do, however, subsist, inheriting their physical properties and, hence, their subsistence, from the bodies on which they depend. For example, place depends for its three-dimensional (non-solid) extension on the bodies that occupy or delimit it. The ontological dependence of space, time, and their novel semantic entities (the lekta) on body, is what takes Stoic metaphysics beyond corporealism to non-reductive physicalism, beyond a merely sorted ontology to an ordered, one-world metaphysics. Each incorporeal counts as Something according to the Stoic criterion for subsistence (hence, the theory is non-reductive), and what they have in common as incorporeals (and what makes the account physicalist), is their dependence on underlying body. -/- In addition to the incorporeals, the Stoics also recognize the subsistence of things like creatures of fiction and geometrical limits, which they classify as neither corporeal nor incorporeal. What these entities have in common is that they are products of thought; and since thoughts are themselves bodies according to Stoic corporealism, this remains a physicalist account. As before, the account is not Meinongian; neither all objects of thought, nor all products of thought count as Something. Indeed, the Stoics’ eliminative treatment of universals (and Forms) turns on their denying concepts (ennoēmata) a place on the ontological map altogether — concepts are simply not Somethings (and, again, not some further category of Not-Somethings, intermediate between Something and nothing at all). If all this is right, then the Stoics are not flat-footed materialists or ersatz Platonists, as so often assumed, but our first non-reductive physicalists. (shrink)

This paper brings, for the first time, an interesting modern description of the Patricius’ phenomenological theory of tides and its modern relativistic understanding. Famous historians of science are emphasizing Patricius’ treatise on tides, which had been of primary importance for Kepler in his attempts at formulating the universal character of attraction. Patricius had tried to explain the variety of phenomena of tides in various seas as part of his model of the universe . He correctly recognized the Moon and (...) the Sun as two general causes of tides , but failed to see the role of gravity. Patricius rather ascribed tides, within the framework of his general philosophy, to be caused by light and heat . Science after Patricius explained tides as an effect of gravity , and later in the 20th century as an effect of spacetime curvature . The mathematical description of tides within Newton’s theory of gravitation was shown in the paper, along with a more refined calculation of the same phenomenon in curved spacetime within the general relativity theory for the case of weak gravitational fields . The general relativistic correction found to be very small compared to the classical Newtonian expression, as one should expect when dealing with weak gravitational fields. Both theories – Newton’s and Einstein’s – despite their precision and beauty in describing tides, do not, however, describe tides in such detail as Patricius’ theory which includes the local features of the phenomenon. At various symposia all over the world dedicated to his miraculous year of 1905 , Einstein has been recognized as the greatest physicists of the 20th century, and with Newton the two greatest physicists of all times. In the paper Patricius is understood as a direct predecessor of Kepler in the theory of tides, a hundred years before Newton. (shrink)

Up to the present time the science of physics has given us no purely physical theory by which the characteristic formal properties of sensation can be derived.

We will present a theory in which the characteristic properties of sensation are derived from postulated physical entities. (shrink)

Attributed to Alexander of Aphrodisias -the leading ancient commentator on Aristotle -the Quaestiones exemplify the process through which Aristotle's thought was organized and came to be interpreted as "Aristotelianism." This volume of R.W. Sharples's translation, together with his earlier translation of Quaestiones 1.1-2.15, makes the Quaestiones available in its entirety for the first time in a modern language. The Quaestiones are concerned with problems of physics and metaphysics, psychology and divine providence. Readers interested in Aristotle's psychological views will find the (...) second half of the Quaestiones particularly valuable. Ten of the problems discussed involve issues raised in Aristotle's On the Soul, including the unity of apperception and the transition from first to second actuality in the act of contemplation. An additional twelve problems relate to aspects of physical theory such as infinity, necessity, and potentiality. Quaestio 2.21 concerns divine providence and helps supplement our knowledge of Alexander's position. A study of the Quaestiones also suggests how interpretations of Aristotle were influenced by doctrines of Hellenistic philosophy. Translated first into Arabic and then into Latin, excerpts from the Quaestiones played a significant role in the transmission of ancient Greek philosophy to the medieval world. (shrink)

These are three welcome works on medieval logic. The Summa Logica of William of Ockham has long been a classic, and scholars have been waiting for this critical edition, begun almost a quarter of a century ago by Philotheus Boehner and finally brought to completion by the combined efforts of Stephen Brown and especially Gedeon Gal, now the general editor of the Opera Philosophica et Theologica being prepared at the Franciscan Institute at St. Bonaventure University. The editors date this work (...) after the Commentary on the Sentences, two volumes of which have already appeared in the above mentioned series. It also postdates Ockham’s commentaries on Porphyry, the Praedicamenta, Perihermenias, and Sophisticis Elenchis, as well as the first four books of Aristotle’s Physics. As a terminus ante quem the editors take the fifth book of this same Physics and see it as certainly prior to the Tractatus de praedestinatione, and to the De corpore Christi and De Sacramento Altaris. Parts of the Quodlibetal questions, however, precede it, and others follow. Loux’s translation, unfortunately, antedated this splendid edition of the Summa Logicae, being based on only the partial, earlier edition of Boehner. Nevertheless, it is a useful instrument providing a good and relatively complete introduction to the basic themes of Ockham’s philosophy of language as well as his ontology. A spot check reveals some misprints, e.g., on pp. 56, 192 and on page 38, lines 68-83 of the Latin edition he used have not been translated. The work is introduced by two essays: "The Ontology of William Ockham" and "Ockham on Generality"—the latter dealing with his theory of supposition. Nuchelmans’ interesting work, though it deals mostly with the medieval history of propositions as bearers of truth and falsity, contains some six chapters which trace the history of the term as early as Plato’s treatment in the Sophist, through Aristotle and the important Stoic lekton and axioma. He also concludes with a useful chapter on the significance of a true propositio, both as a mode of being of a thing and as the mental conception.—A.B.W. (shrink)

In this work Ockham proposes a theory of simple predication, which he uses in explicating the truth conditions of progressively more complicated kinds of propositions. His discussion includes what he takes to be the correct semantic treatment of quantified propositions, past tense and future tense propositions, and modal propositions, all of which are receiving much attention from contemporary philosophers. He also illustrates the use of exponential analysis to deal with propositions that prove troublesome in both semantic theory and (...) other disciplines, such as metaphysics, physics, and theology. This type of analysis plays an essential role in his substantive philosophical and theological works, and in many cases then can hardly be understood without a prior acquaintance with this section of the Summa. An introduction by Alfred J. Freddoso clarifies and summarizes Ockham's theory, discusses certain philosophical problems which it engenders, and proposes new interpretations for parts of it. The essay will be helpful both to those interested in Ockham as a historical figure and to those interested in his substantive systematic contributions to logical theory. (shrink)

In this article I investigate what the Stoic doctrine of the two principles, God and matter, owes to Plato. I discuss recent scholarly views to the effect that the Stoics were influenced by Old Academic interpretations of the Timaeus and argue that, although the Timaeus probably did play a role in the genesis of the Stoic doctrine, some role was also played by a dualist theory of flux set forth in the etymologies of the Cratylus. I also (...) discuss Theophrastus’ account of Plato’s achievements in physics (fr. 230 FHS&G) and the report of Old Academic physics contained in Cicero’s Academica, 1. 24–9, and commonly taken to go back to Antiochus of Ascalon, and I show that those reports too are likely to have been influenced by the Cratylus.

The aim of this article is to examine some of the anatomical implications of Campanella's theory of magic, focusing in particular on his crìtique of Aristotle's and Galen's anatomical views. By magic Campanella meant first and foremost communication of energy and knowledge. It is no accident that he viewed both medicine and rhetoric as constitutive disciplines of magic. In doing so, he appealed to the time-honoured notion of the magic of the word theorised in ancient times by the sophist (...) Gorgias. The distinctive feature in Campanella's system of magic is that the word is both a symbolic and a physical entity. Meaning flows from nature to the mind and from the mind to nature. Words are both carriers of meanings and physical agents of psychosomatic transformation. As can be demonstrated by pointing to such paradigmatic cases as natural divination and prophecy, the force of the imagination, the patient's trust in the power of the physician or the healer, and the many influences that air exercises on the body, Campanella's theory of magic rests on a definite anatomo-physiological basis. The most original aspect, though, is the way in which Campanella reinterpreted Arìstotle's and Galen's prìnciples of anatomy so that he could adapt his medical views to the broader framework of his theory of magic (practice), on the one hand, and metaphysics (theory), on the other. In addition, Campanella's onginal account of emotions and passions supported a comprehensive system of magical practice that dispensed with the basic principles of both Aristotle's and Galen's physiology. Campanella was convinced that the vital operations of the body could not be explained by simply relying on the unsentient functions of the vegetative soul (Aristotle) or on the natural faculties of the body (Galen), nor could they be accounted for by assuming the existence of incorporeal souls (Aristotle) or bodily temperaments (Galen). By circumventing both Aristotle's hylomorphism and Galen's vital matenalism of the temperaments, and by appropriating the Stoic view of rational pneuma, he managed to produce a physiological model that was more flexible in dealing with the complex interplay of knowledge, action and appetite, and above all, better suited to account for a universe in which the flow of life and meaning encompassed varìous levels of communication.

This chapter examines the ancient Stoic theory of the physical composition of pneuma, how its composition relates to pneuma’s many causal roles in Stoic philosophy, and to what extent each of the first three leaders of the Stoic school accepted the claim that pneuma pervades the cosmos. I argue that pneuma is a compound of fire and air. Furthermore, many functions of pneuma can be reduced to the functions of these elements. Finally, it is likely that (...) each of the early Stoics posited a pervasive cosmic pneuma. This paper also explores the nature of pneuma’s tensile movement and offers an account of fire and air’s roles in causing its motion. (shrink)

Several authors have recently attempted to provide a physicalist analysis of causation by appealing to terms from physics that characterise causal processes. Accounts based on forces, energy/momentum transfer and fundamental interactions have been suggested in the literature. In this paper, I wish to show that the former two are untenable when the effect of enclosed electromagnetic fluxes in quantum theory is considered. Furthermore, I suggest that even in the classical and non-relativistic limits, a theory of fundamental interactions should (...) not be reduced to either a theory of forces or of energy/momentum transfer, but should be understood as a classical account of mutual interactions. Causal links are therefore correctly characterised by generalised potentials. This leads to some speculation regarding the fundamental ontology of interactions and, in particular, the role of the quantum mechanical phase. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 61.1 (2000) 19-37 [Access article in PDF] Eudaimonism and Theology in Stoic Accounts of Virtue Michael Gass The Stoics were unique among the major schools in the ancient world for maintaining that both virtue and happiness consist solely of "living in agreement with nature" (homologoumenos tei phusei zen). We know from a variety of texts that both Cleanthes and Chrysippus, if not (...) also Zeno, characterized such conduct both in essentialist terms, as a matter of living purposively in a manner natural for the human species, and in cosmological terms, as a matter of living in agreement with the purposes of nature as a whole, this being regarded as identical to Zeus. This is not to suggest, however, that cosmo-theological speculation figured prominently in the ethical systems of the early Stoics. Judging from extant summaries and discussions of Stoic ethical doctrines, those doctrines were justified in a dialectical fashion, not by appeal to facts about the purposive order of nature but simply from an analysis of ethical concepts patterned after similar analyses by earlier philosophers (most notably, Aristotle). It is this kind of learning that Chrysippus apparently had in mind when he maintained that ethics should be studied prior to undertaking a systematic investigation of nature: [T]here are three kinds of philosopher's theorems, logical, ethical and physical.... [W]hat should be ranked first of these are the logical, next the ethical, third the physical; and what should come last in the physical theorems is theology. 1On the other hand, as we learn from the testimony of Plutarch (and also from other indirect textual evidence examined recently by Jacques Brunschwig), 2 [End Page 19] Chrysippus also believed that physics in general and theology in particular yield a quite distinct, demonstrative knowledge of the matters first studied in ethics. A. A. Long and others have suggested that such knowledge was regarded by the Stoics as encompassing not just information about the ways in which virtuous living is encouraged by, and fits into, the wider aims of nature at large but also a deeper understanding of the very essence of virtue. 3 Specifically, virtue is revealed to consist in a conscious and deliberate harmonization of one's actions with the purposes of the divine architect. Thus, under this interpretation of their ethical intentions, the Stoics thought of the initial, analytical approach to ethics as necessarily incomplete even in its treatment of strictly ethical topics; the systematic study of nature was thought to impart additional wisdom regarding ethical matters.In her recent study of ancient ethical theories, Julia Annas seeks to counter this view of the place of cosmo-theological speculation in early Stoicism by arguing that such a religious characterization of virtue is incompatible with the eudaimonism to which all schools of ancient philosophy, including Stoicism, were committed. 4 She concedes that first Cleanthes and then much later the Roman Stoics did regard virtue in religious terms, but in her assessment this represents a radical departure from mainstream Stoic thinking on this subject (which is identified mostly with the views of Chrysippus and his disciples, all of whom were clearly and consistently committed to the eudaimonistic model of ethical inquiry). Annas argues that whereas the Stoic sage was traditionally depicted as a person whose commitment to morally appropriate conduct stems from his own rational reflection on his own needs and interests, a person who identified completely with the aims of the divine architect in his purposive activity would be someone who surrendered his right to decide for himself what his needs and interests are, and who therefore could even be required to act in violation of what he might judge by himself to be crucial to his happiness.In what follows I demonstrate that this argument, often advanced in the literature as a reductio ad absurdum of divine command theories of morality, falls wide of the mark in the present case due to the fact that those Stoics who characterized virtue in religious terms did so apparently because they regarded a complete identification with...

Huston Smith has argued that the universal source of wholeness, which he refers to as the primordial tradition, is essential to a meaningful life. Indeed embracing this tradition is, said Smith, an act of rejoining the human race. Our current forms of organized religion offer us ritualized expressions of this tradition, yet often fail to provide us with transpersonal growth; it is this transpersonal growth that reconnects us with the source of religion. This essay differentiates mainstream religion from a way (...) that we can begin to construct a physical theory of the primordial tradition–a necessary first step toward reclaiming the source of religion.

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.

The Stoics are often cited as predecessors of Kantian theories of cosmopolitan justice. After setting out the various types of contemporary cosmopolitanism, I argue that the Stoic doctrine does not match any of these categories. The core of the Cosmic City doctrine in the early Stoa is cosmological and theological, not moral or political. It concerns the Zeus' governance of the physical universe and the proper relation of our individual natures to the nature of the whole. Although the Stoics (...) do appeal to this doctrine in moral contexts, the underlying concepts of law, autonomy, and citizenship are quite different from their contemporary counterparts. As part of my argument I attempt to explain how this theological doctrine came to be expressed in a de-politicized political [abstract ends here]. (shrink)

: In the concluding pages of his Epistolae duae de motu impresso a motore translato (1642), Pierre Gassendi provides a brief summary of the explanation of the tides found in Galileo's Dialogue over the Two Chief World Systems (1632). A comparison between the two texts reveals, however, that Gassendi surreptitiously modifies Galileo's theory in some crucial points in the vain hope of rendering it more compatible with the observed phenomena. But why did Gassendi not acknowledge his departures from the (...) Galilean model? The present article argues that cautiousness was just one of the reasons that stopped the French priest from turning Galileo's theory into his own theory. He was probably also aware of the fact that Kepler's model of planetary motion, which he endorsed in the Epistolae, could not be reconciled with Galileo's explanation of the tides. In the postumously published Syntagma philosophicum (1658), Gassendi tried to mend this major inconsistency by arguing that Galileo's theory of the tides not only remained valid, but became even more coherent, if one attributed to the Earth an elliptic orbit. But given that in the Syntagma Gassendi officially adhered to the Tychonic system, his effort to reconcile Kepler and Galileo, while already unconvincing by itself, appears completely futile.

Sources for Stoicism present conflicting accounts of the Stoic principles. Some suggest that the principles are inseparable from each other. Others suggest that they are separable. To resolve this apparent interpretive dilemma, I distinguish between the functions of the principles and the bodies that realize those functions. Although the principles cannot separate when realizing their roles, the Stoic theory of blending entails that the bodies that realize those roles are physically separable. I present a strategy for further (...) work on the principles in light of this interpretation. (shrink)

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)

Recently, mathematical models based on quantum formalism have been developed in cognitive science. The target articles in this special issue of Topics in Cognitive Science clearly illustrate how quantum theoretical formalism can account for various aspects of human judgment and decision making in a quantitatively and mathematically rigorous manner. In this commentary, we show how future studies in quantum cognition and decision making should be developed to establish theoretical foundations based on physical theory, by introducing Taketani's three-stage theory (...) of the development of science. Also, implications for neuroeconomics (another rapidly evolving approach to human judgment and decision making) are discussed. (shrink)
