Air is an immersive substance that envelopes us and binds us together, yet it has dominantly been taken for granted and left out of educational and other theorizations. This article develops a conceptualization of the pneumatic common in order to address this gap. The specific intervention staged is within recent educational literature on the common by Noah De Lissovoy, Tyson E. Lewis, and Alexander Means. This literature is surveyed and analyzed in relation to educational theory, curriculum, pedagogy, and policy. (...) Claiming that the air is a central feature of and paradigm for the common, I then concentrate on making the air conditions of the educational common explicit. I do this through a theoretical, historical, and sociological reading of air conditioning. While this explicitation is itself educational, I return to the educational common at the end of the article to ask how and what we can learn in, with, and from the air. (shrink)

In most of the more lively fields of physical enquiry in the first three decades of the seventeenth century, a striking contrast may be observed between the antiquity of the problems attacked, and the innovatory procedures applied to solve them. None of these questions, inherited from a past now remote, seemed more pressing than the time-honoured controversy of the plenum versus the vacuum, especially as the concept of the atomic structure of matter was so closely associated with the existence of (...) the void. The more one studies the arguments produced at that time, the more one will be impressed with the value and importance, for the vacuists and the atomists, of the Pneumatics of Hero of Alexandria. When we read Galileo's explanation of combustion, “the extremely fine particles of fire, penetrating the narrow pores of the metal would fill the minute intervening vacuum, and would set free these minute particles from the forced attraction which these same vacua exert’, we can hear clear echoes of Hero's account of disseminated micro-vacua. Now Hero's work is clearly divided into two sections: a theoretical preface and a collection of 78 “pneumatic devices”. One might be tempted to claim that he, rather than his fellow-atomist Lucretius, inspired the first tentative syntheses of seventeenth-century atomism but it would still be necessary to agree that his chief contributions to the achievements of that generation lie in the experimental techniques which they derived from his instrumentation. Were it not for the popularity of his pneumatic demonstrations, he could never have won such a great reputation as a natural philosopher. Without that reputation, his opinions on this topic would not have been valued as almost equal to those of the mighty Aristotle, especially since he was so decidedly in the minority. (shrink)

This paper is an attempt at presenting a convincing reading of the first sentences of PI § 109, especially of its third sentence. There Wittgenstein mentions what he calls "the pneumatic conception of thought", which by Miss Anscombe is translated as "the conception of thought as a gaseous medium". By comparing the relevant sentences with their sources in Wittgenstein's manuscripts and additional parallels it is found that Anscombe's rendering is liable to be misleading. Wittgenstein's notion of "pneuma" is likely (...) to be inspired by a conception of the kind elucidated by Oswald Spengler, for instance, according to whose account pneuma is to be understood as a sort of body (Seelenkörper). If you take this as your central image, the pneumatic conception alluded to in PI § 109 is one which can be tracked down in Wittgenstein's early as well as in his middle-period work. In this remark (PI § 109), Wittgenstein tries to mention both helpful and misleading features of his earlier ways of thinking, and what he now calls the "pneumatic conception" can be seen to be the foil for both sorts of features. The central idea is that the core of language contains a scaffolding of rules whose ("pneumatic") substance is the same as that of our thought. In accordance with this view the logical structure of thought is held to be identical with that of language and reality—a notion which fits parts of the Tractatus as well as parts of the original "grammatical" conception developed in the early 1930ies.

Pneumatic muscle actuators own excellent compliance and a high power-to-weight ratio and have been widely used in bionic robots and rehabilitated robots. However, the high nonlinear characteristics of PMAs due to inherent construction and pneumatic driving principle bring great challenges in applications acquired accurately modeling and controlling. To tackle the tricky problem, a single PMA mass setup is constructed, and a back propagation neural network is employed to identify the dynamics of the setup. An offline model is built (...) up using sampled data, and online modifications are performed to further improve the quality of the model. An adaptive controller based on BPNN is designed using gradient descent information of the built-up model. Experiments of identifying the PMA setup using BPNN and position tracking by adaptive BPNN controller are performed, and results demonstrate the good capacity in accurate controlling of the PMA setup.

This paper deals with an aspect of John Philoponus’ psychology, a 6th century Byzantine writer, which marks the early phase of his philosophical career. It is the ochēma/pneûma theory, which in Philoponus’ case represents an unusual fusion of Aristotelian, Platonic, and Stoic philosophy with Galenic physiology and anatomy. In this paper, we examine how this Christian Neoplatonist attempts to assimilate elements of two ancient traditions – philosophical and medical – into a peculiar psychological concept.

Two major problems in understanding Joseph Priestley are that he wrote so much and over such a wide area. The nineteenth-century edition of his collected works fills 25 volumes—and that leaves out the science! In discussing a man like Priestley, therefore, one cannot hope in a single lecture to do justice to the wide range of his interests or even to summarise adequately his many contributions to science. Fortunately much of the scientific work is fairly well known, for example his (...) discovery of many new gases or ‘airs’, as he preferred to call them. It might be appropriate, therefore, to try to put Priestley's pneumatic chemistry in a wider context and in particular to relate it to his career. Priestley was not only an important man of science. He was also an outspoken theologian, a literary figure and a family man, and all of these roles will have to be taken into consideration when the definitive biography is written. (shrink)

In this paper, in order to achieve automatic defect identification for pneumatic pressure equipment, an improved feature extraction algorithm eddy current pulsed thermography is presented. The presented feature extraction algorithm contains four elements: data block selection; variable step search; relation value classification; and between-class distance decision function. The data block selection and variable step search are integrated to decrease the redundant computations in the automatic defect identification. The goal of the classification and between-class distance calculation is to select the (...) typical features of thermographic sequence. The main image information can be extracted by the method precisely and efficiently. Experimental results are provided to demonstrate the capabilities and benefits of the proposed algorithm in automatic defect identification. (shrink)

The interaction between science and technology in the Industrial Revolution has been debated by various authors over the years. Most recently, Ursula Klein has described eighteenth-century chemistry as an interconnected system of science and technology because of the inherently productive nature of chemical experimentation. The technology used in the nineteenth gaslight industry follows the pattern that Klein describes: gaslight technology was derived from the academic studies of eighteenth-century pneumatic chemists. The foundation of the technology in science included first, a (...) knowledge about inflammable gases and their properties, and second, various instruments and processes developed for the study of gases. Although inflammable exhalations had been known long before the eighteenth-century, it was only with the work of Priestley, Volta, Berthollet, and other chemists that their properties and characteristics, including the multiplicity of species of inflammable gases, became known. The instruments and processes of pneumatic chemistry that were incorporated into gaslight apparatus were the retort, the pneumatic trough, lime purification of carbon dioxide and hydrogen sulphide, and finally the gasometer. The first important instance of lighting with inflammable gases, that of J. P. Minckelers in 1785, demonstrates that pneumatic chemistry formed part of an interconnected network of science and technology, as does the work of other early gaslight pioneers such as Philippe Lebon, Zachäus Winzler, and William Murdoch. Lebon came to gaslight through the investigation of distillation processes, and later thought of using the inflammable gas produced in this way. Zachäus Winzler, an Austrian chemist, recreated Lebon's thermolamp from the instruments in his laboratory after hearing descriptions of it. In the case of William Murdoch, he incorporated the pneumatic apparatus that James Watt had built for Thomas Beddoes. (shrink)

This article in an attempt to identify the precise way in which Robert Boyle provided a mechanical account of the features that distinguish liquids and air from solids and from each other. In his pneumatics, Boyle articulated his notion of the ‘spring’ of the air for that purpose. Pressure appeared there only in a common, rather than in a technical, sense. It was when he turned to hydrostatics that Boyle found the need to introduce a technical sense of pressure to (...) capture the fluidity of water which, unlike air, lacked a significant spring. Pressure, understood as representing the state of a liquid within the body of it rather than at its surface, enabled Boyle to trace the transmission of hydrostatic forces through liquids and thereby give a mechanical account of that transmission according to his understanding of the term. This was a major step towards the technical sense of pressure that was to be adopted in Newton’s hydrostatics and in fluid mechanics thereafter. (shrink)

A central claim of the Christian faith is that Jesus is not only fully human (and fully God), but that he reveals true humanity to us. This requires that all of our anthropologies, in some way, ground themselves in Christology, providing a ‘Christological anthropology’. Consequently, any Christological anthropology requires some formulation of Christology proper. In light of this, the main contention of the present paper is that one cannot adequately formulate a Christological anthropology without including a pneumatic Christology. The (...) justification for this necessity can be articulated through the concept of fundamental need. The incarnate Logos, Jesus of Nazareth, fundamentally needed the Spirit in the same way that all human persons fundamentally need the Spirit. ‘Fundamental need’, as a technical concept, can help to clarify both the continuity and discontinuity between Jesus’ likeness to all humanity. This does not collapse the ‘who’ of the incarnation into the many ‘who’s’ of humanity since the incarnate Logos always possessed this Spirit as his own Spirit of Sonship, as opposed to how non-divinely hypostasized human persons must receive the Spirit of Sonship by adoption. The distinctiveness and similarity between Jesus and all of humanity can be most clearly seen by paying special attention to the difference between incarnation and indwelling. Thus, by examining incarnation and in-dwelling, as well as introducing fundamental need into theological discourse, the significance of the Spirit for informing both Christology and anthropology will be made clear.

Sometime between 1589 and 1591, a momentous discovery was announced in Florence; or, at least, a discovery thought to be momentous by its promoter: "The true form of the octave is the octuple [ratio 8:1] and not the duple [2:1]".1 Thus taken out of context, we might be forgiven if we failed either to share the author's enthusiasm or to recognize the importance of his finding.

This article examines the development of pneumatic medicine as practised by Erasmus Darwin, Thomas Beddoes and Joseph Priestley, and the support for their experimental trials by other Dissenting doctors and industrialists including Boulton, Watt and Wedgwood. The article examines their belief that if one could create the conditions under which `good air' could be manufactured — where the work of Dissenting chemists and doctors was embraced rather than condemned, supported rather than attacked — then conditions, political and medical, under (...) which a healthy country will flourish will prevail. Contra the claim made by Roy Porter that doctors, such as Erasmus Darwin, were `profoundly troubled by what they saw as the counterproductive impact on health produced by the spread of progressive ideas, refined culture, and modern, commercial, urban values', I believe that it was precisely those progressive values that led Dissenting doctors and pneumatic chemists to believe that by applying the same principles that led to the phenomenal industrial and commercial success of their friends like Boulton, Watt and Wedgwood, they could improve population health by attempting to reform simultaneously politics and therapeutics.

The coronavirus disease 2019 (COVID-19) pandemic has brought significant changes to the life of the Christian church in Indonesia. Such changes can degrade the essence of the fellowship of believers. The reality of the COVID-19 pandemic, which became the church’s starting point, has triggered a change in the pattern of carrying out its duties and services to the people and their environment. The church can adapt and transform its ministry innovations as a living organisation. The church needs to reinterpret the (...) effectiveness of its presence through adapting new service patterns, namely onsite services to virtual services or hybrid services, to remain relevant to every dimension of rapid change in all aspects. This research study analyses the actualisation of church ecclesiology in the midst and after the pandemic. Using descriptive qualitative methods with interactive data analysis from Miles and Huberman, the following points have been found: (1) virtual ministry as a church reality, (2) a pneumatic encounter spirituality characterises the church, (3) ecclesiology in the context of universal communion and (4) the sacrament as a means of manifesting divine power.Contribution: This study provides the concept of collaboration between ecclesiology as a principle and technology as a method. Ecclesiology and technology can realise the ministry of church unity. Collaboration between principles and methods in the church will build a flexible church in all conditions. However, the principles and duties of the church vocation are not neglected. (shrink)

Robert Boyle thought that his scientific achievements in pneumatics and chemistry depended on, and thus provided support for, his mechanical philosophy. In a recent article in this journal, Alan Chalmers has challenged this view. This paper consists of a reply to Chalmers on two fronts. First it tries to specify precisely what ‘the mechanical philosophy’ meant for Boyle. Then it goes on to defend, against Chalmers, the view that Boyle's science does support his natural philosophy.Keywords: Robert Boyle; Mechanical philosophy; Reductionism.

This paper argues that, contrary to the claims of Alan Chalmers, Boyle understood his experimental work to be intimately related to his mechanical philosophy. Its central claim is that the mechanical philosophy has a heuristic structure that motivates and gives direction to Boyle's experimental programme. Boyle was able to delimit the scope of possible explanations of any phenomenon by positing both that all qualities are ultimately reducible to a select group of mechanical qualities and that all explanations of natural phenomena (...) are to be in terms of the operations of machines and are to appeal only to qualities that are already familiar. This is illustrated by his investigations into the Torricellian experiment. Boyle's explanation of the elevation of the mercurial cylinder by appeal to the spring of the air was an intermediate mechanical explanation. Boyle was convinced that the spring of the air was ultimately reducible to the mechanical qualities. This in turn had implications for his research into the cause of respiration. In a move that was both parsimonious and consistent with the broad requirements of the mechanical philosophy, Boyle was able to solve the problem of the cause of the inflow of air into the lungs by appeal to his research in pneumatics. This application of a mechanical explanation in pneumatics to physiology is just what one would expect if the mechanical philosophy was as universal as Boyle claimed it to be. Therefore, far from Boyle's experiments having a life of their own, they were clearly directed by and understood in terms of the mechanical philosophy.Keywords: Air-pump; Boyle; Chalmers; Experiment; Explanation; Mechanism.

It has long been thought that the ancient Greeks did not take mechanics seriously as part of the workings of nature, and that therefore their natural philosophy was both primitive and marginal. In this book Sylvia Berryman challenges that assumption, arguing that the idea that the world works 'like a machine' can be found in ancient Greek thought, predating the early modern philosophy with which it is most closely associated. Her discussion ranges over topics including balancing and equilibrium, lifting water, (...) sphere-making and models of the heavens, and ancient Greek pneumatic theory, with detailed analysis of thinkers such as Aristotle, Archimedes, and Hero of Alexandria. Her book shows scholars of ancient Greek philosophy why it is necessary to pay attention to mechanics, and shows historians of science why the differences between ancient and modern reactions to mechanics are not as great as was generally thought.

This paper extends the sensibilities of the Gilligan-Kohlberg debate into classical political economy and makes links with modern psychotherapeutics and the psychological development of individuals. The model of moral maturity represented in contemporary psychological theories is posited as the direct descendant, not only of Immanuel Kant, as is generally argued, but also of the universal, homogenous agent of classical economics; the ‘rational economic man’ representedin the writings of Adam Smith and J. S. Mill. Both thinkers lent their support to the (...) creation of an order which produces (masculine) actors who are ’rational’ self-governing, separative, competitive, self-asserting, self-interested, acquisitive, pecuniary and driven to success by a desire for the social recognition afforded by consumerism; the same order which typically designates women moral failures and which renders them largely invisible. Liberalism generates conditions which enable it to sustain and reproduce itself at the psychic level. The assumption of the market as the paradigmatic social interaction and its status as the analytical and moral starting point in liberal capitalism infects the putatively private domain of ‘self-governance’ and contemporary psychotherapeutics; the development and management of the self in contemporary culture is a direct reflection of the imperatives and assumptions of market society. The separative self is the ‘healthy’ self, hence the parallel emphasis in modern therapy on ‘individuation’ as the highest level of psychological evolvement. Gilligan’s ‘care ethic’ is approached with some scepticism, nevertheless, her critique of Kohlberg guides us towards a more comprehensive critique of the ‘pneumatic’ and political assumptions of liberalism.

The ArgumentThis paper charts eighteenth-century chemistry's transition from its definition as an art to its proclaimed status as a science. Both the general concept of art and specific practices of eighteenth-century chemists are explored to account for this transition. As a disciplined activity, art orients practitioners' attention toward particular directions and away from others, providing a structured space of possibilities within which their discipline develops. Consequently, while chemists throughout the eighteenth century aspired to reveal nature's “true voice,” the path of (...) their investigations was directed by and toward their laboratory manipulations. So long as the chemical community maintained an ethos of polite cooperation and eschewed theoretical wrangling, this point was hidden by a rhetoric of “matter of fact” reporting. But as “facts” mounted in the 1770s and 1780s, especially in pneumatic chemistry, cooperation gave way to contention as chemists sought to name and organize their findings without the guidance of a communally accepted “natural” system. Lavoisier and his fellow “new” chemists offered a forceful solution to this dilemma by introducing a revolutionary network of theories, nomenclature, and instruments that unabashedly fused the productive manipulation of their laboratory work with what they claimed as the structure and activity of nature.

The ancient Neoplatonic doctrine that the rational soul has one or more vehicles—bodies of a semi-material nature which it acquires during its descent through the spheres—plays a crucial part in Marsilio Ficino’s philosophical system, especially in his theory of sense-perception and in his account of the afterlife. Of the soul’s three vehicles, the one made of more or less rarefied air is particularly important, according to Ficino, during the soul’s embodied existence, for he identifies it with thespiritus, the pneumatic (...) substance based in the brain which was believed to serve as an instrument for perception and imagination. He refers to the vehicles in his arguments against the theory of the transmigration of souls into the bodies of animals, claiming that the imaginative suffering experienced after death by souls in their aerial bodies are much more acute than the physical pain they might feel in bodies made of flesh and blood. Since the power of the imagination, for Ficino, is stronger than that of the four senses, the soul’s perceptive activity is more intense after death, when it has lost its earthly body and lives instead in a body made of air. The vehicles, moreover, provided Ficino with evidence for the individual immortality of souls, a doctrine that he was attempting to demonstrate philosophically against the position of Averroes and his followers. In his view, the vehicles ensured the survival after death of two faculties which were intimately connected to personal identity: the imagination and memory. By pointing out the role of the vehicles in transporting the soul’s innermost representations and memories through the universe, Ficino was able to show that the distinguishing traits of our personality are not lost with bodily death, but survive along with the vehicle that carries them.

Mi Gyung Kim (2008) has challenged the historiographical assumption that phlogiston was the paradigmatic concept in eighteenth century chemistry. Her analysis of the operational, theoretical, and philosophical identities of phlogiston demonstrates how Stahlian phlogiston was appropriated into the burgeoning field of affinity theory. However, this new French conception of phlogiston was destabilized by the introduction of Boerhaave's thermometrics. By extending this story through 1790, I will show that British pneumatic chemists integrated new understandings of heat with an affinity based (...) operational definition of phlogiston and thereby stabilized the concept. What resulted was a new and very different phlogiston. (shrink)

William Newman construes the Scientific Revolution as a change in matter theory, from a hylomorphic, Aristotelian to a corpuscular, mechanical one. He sees Robert Boyle as making a major contribution to that change by way of his corpuscular chemistry. In this article it is argued that it is seriously misleading to identify what was scientific about the Scientific Revolution in terms of a change in theories of the ultimate structure of matter. Boyle showed, especially in his pneumatics, how empirically accessible, (...) intermediate causes, as opposed to ultimate, mechanical ones can be explored and identified by experiment. Newman is right to observe that Boyle constantly sought intimate links between chemistry and the mechanical philosophy. However, by doing so he did not thereby significantly aid the cause of attaining experimental knowledge of chemical phenomena and the support that Boyle’s chemistry provided for the mechanical philosophy was weaker than both Boyle and Newman imply. Boyle was intent on articulating and defending a strict, mechanical account of the ultimate structure of matter to be sure, but his contributions to the new experimental science in general, and chemistry in particular, are best seen as distinct from that endeavour.Keywords: Chemistry; Mechanical philosophy; Corpuscular philosophy; Experiment; Robert Boyle; William Newman.

Pentecostalism meant a break with Protestant anthropology hostage to the epistemology of Modernity. As Havey Cox explains, these American movements in the early years of the 20th century filled the ecstatic deficit left by evangelicals, pointing towards the affective system of knowledge of reality, an affective epistemology. If, on the one hand, the Pentecostal experience encouraged the shift from the margin to the center of corporeality, on the other, the violated and subjugated bodies became visible and empowered, because marginalized groups, (...) excluded by the American and Brazilian Protestant establishment, were and are protagonists. Pentecostal movements are presented as a presence in the world and religious practice that reveals the defense of fundamental rights, especially in the militancy experience of racial justice, which does not mean a theoretical defense, but community experiences of excluded bodies that gain pneumatic status. The essay discusses the relationship between religion, human rights and racial issues, pointing out how Pentecostalism represents intuitions for a more fraternal and egalitarian society. (shrink)

Nature's simplest atom and mother of all matter, hydrogen feeds the stars as well as interlaces the molecules of their biological descendants – to whom it ultimately whispers the secrets of quantum reality. Hydrogen’s most prevalent earthly guise lies within the composition of water. A slight electrical disturbance can split water into hydrogen and oxygen gas, resulting in diaphanous bubble clouds slowly rising towards the liquid’s surface. Though the founding fathers of electrochemistry posited that the mass of liberated bubbles is (...) directly proportional to the input voltage, certain modes of electrolysis release more energy than is spent. One such mode involves water’s Janus-faced capacity to react as either an acid or a base. Emanating from an array of electrodes at the bottom of a water-filled chamber, strings and strata of hydrogen bubbles meticulously trace their emergent surroundings. In addition to eddy formations incited by a bubble's rapid growth and subsequent detachment from the electrode surface, acoustic vibrations permeate the two-phase fluid. As the sonic frequency and amplitude rises, the hydrogen bubbles start to coalesce with one another. When the sound field reaches maximum intensity, it can trap bubbles within its antinodes. The vibrations are generated both by transducers and by the bubbles themselves, which emit frequencies ranging from the audible spectrum to as high as 800 kHz. A white laser sheet scans and illuminates the hydrogen bubble trajectories. Each quivering bubble-lens divides the white light into its constituent spectrum of colors. While scanning, the laser sheet also swiftly pulsates and thereby extends the perceivable resolution of micro-momentary bubble dynamics. Before it even begins to map out its vibratory environment, a bubble goes through various stages of spatio-temporal evolution. During the first phase of growth, a bubble nucleus inflates linearly with time. At the second stage, bubble growth is limited by the diffusion of gas within the liquid, causing its size to increase as the square root of time. The final phase before detachment is limited by the kinetics of dissolved gas production, causing the bubble to grow as the cube root of time.1 Beyond macroscopically observable bubbles, an expanse of nanobubbles hides within the water’s internal architecture. Some researchers presume that these nanobubbles of dissolved gas are the carriers of water’s magnetic ‘memory’, enabling electromagnetic fields to saturate its innards for hours and even days after their initial appearance. In the seas and oceans, the lingering presence of electromagnetic fields photonically imparted by sunlight, triggers the electrolysis responsible for most of the Earth’s hydrogen. An essential form of photosynthesis, solar water splitting is the cleanest and most efficient means imaginable for generating and storing energy. —Evelina Domnitch & Dmitry Gelfand *** Animals and plants are formed in earth and in water because there is water in earth, and there is pneuma in water, and there is soul heat in all pneuma ; so that in a way all things are full of soul. Hence plants and animals quickly form once this gets enclosed; and when this enclosing happens, when the corporeal liquids get heated, a sort of frothy bubble is formed. Now the difference between the various creatures which are produced in this way are due to the stuff which makes up the envelope around the soul-source.2 Throwing light into this pneumatic spray of perdurances, which would otherwise swarm below the threshold of human visibility, Evelina Domnitch and Dmitry Gelfand’s Hydrogeny saturates the viewer’s sensorial space with the nano-architectures of froth. Straddling the cell wall between scientific enquiry and artistic praxis, Hydrogeny , beckons a recasting of Lucretius' clinamen in tune with the technologies of the modern observer. For Lucretius it was the indeterminate swerving of an atomistic layer of reality which accounted for the unpredictability of change and the existence of free will. Taken up by Harold Bloom to describe the swerving of cultural production from that which has already been made, the idea has since been textually redressed by Lacan, Derrida, Serres, Deleuze, Nancy, and Badiou. Here we have been given a kaleidoscopic technique for refining and expanding awareness of our enmeshment with so many nested, atomistic layers of object-bubbles—of things—as Aristotle might say,“full of soul.” The gravitational pull of Hydrogeny ushers a de-centered human spectatorship to the ever more intimate recesses of what media philosopher N. Katherine Hayles calls our capacity for “deep attention.”3 Vaporous attention suspended and re-oriented.

We have always been conscious of the wait for life-changing messages, whether it be the time it takes to receive a text message from your love, for a soldier's family to learn news from the front, or for a space probe to deliver data from the far reaches of the solar system. In this book in praise of wait times, award-winning author Jason Farman passionately argues that the delay between call and answer has always been an important part of the (...) message. Traveling backward from our current era of Twitter and texts, Farman shows how societies have worked to eliminate waiting in communication and how they have interpreted those times' meanings. Exploring seven eras and objects of waiting--including pneumatic mail tubes in New York, Elizabethan wax seals, and Aboriginal Australian message sticks--Farman offers a new mindset for waiting. In a rebuttal to the demand for instant communication, Farman makes a powerful case for why good things can come to those who wait. (shrink)

The early evolutionary history of echinoderms was reconstructed on the basis of structural-functional considerations and application of the quasi-engineering approach of ‘Konstruktions-Morphologie’. According to the presented evolutionary scenario, a bilaterally symmetrical ancestor, such as an enteropneust-like organism, became gradually modified into a pentaradial echinoderm by passing through an intermediate pterobranch-like stage. The arms of a pentaradial echinoderm are identified as hydraulic outgrowths from the central coelomic cavity of the bilateral ancestor which developed due to a shortening of the body in (...) length but widening in the diameter. The resulting pentaradial symmetry is a consequence of mechanical laws that dictate minimal contact surface areas among hydraulic pneumatic entities. These developed in the coelomic cavity (metacoel) in the bilaterally symmetrical ancestor, when from the already U-shaped mesentery with the intestinal tract two additional U-shaped bows developed directly or subsequently. During the subsequent development tensile chords of the mesentery ‘sewed’ the gut with the body wall first in three and secondly in five ‘seams’. During the direct development five ‘seams’ between tensile chords and body wall developed straightly. These internal tensile chords subdivide the body coelom into five hydraulic subsystems (‘pneus’), which eventually arrange in a pentaradial pattern. The body could then enlarge only between the tensile chords, which means that five hydraulic bulges developed. These bulges initially supported the tentacles and finally each of them enclosed the tentacle until only the feather-like appendages of the tentacles projected over the surface. The tentacles with their feathers were transformedinto the ambulacral system, and the bulges become the arms. These morphological transformations were accompanied and partly determined by specific histological modifications, such as the development of mutable connective tissues and skeletal elements that fused to ossicles and provided shape stabilization in form of a calcareous skeleton in the body wall. The organism resulted was an ancestral echinoderm (‘Ur-Echinoderm’) with an enlarged metacoel, stabilized by hydraulic pressure working againsta capsule of mutable connective tissue, skeletal elements and longitudinal muscles. In regard to these reconstructions, the body structure of echinoderms can be understood as a hydraulic skeletal capsule. (shrink)

In this essay, I argue that both human souls and angels are hylomorphic, a position I dub “pneumatic hylomorphism” (PH). Following a sketch of the history of PH, I offer both an analytic and a confessional defense of PH. The former argues that PH is the most cogent anthropology/angelology, given the Christian understanding of the intermediate state and angels. My confessional defense shows that PH plays a crucial role in pro-Nicene theology. I close with an assessment of contemporary anthropological (...) alternatives, and conclude these do not advance the discussion beyond the patristic and medieval alternatives; thus PH remains the most cogent and confessional sound option.
