Ancient Greek and Roman Philosophy of Science

This article concerns the so-called irrigation system in the Timaeus’ biology (77a-81e), which replenishes our body’s tissues with resources from food delivered as blood. I argue that this system functions mainly by the natural like-to-like motion of the elements and that the circulation of blood is an important case study of Plato’s physics. We are forced to revise the view that the elements attract their like. Instead, similar elements merely tend to coalesce with each other in virtue of their tactile (...) features as the atomists describe. The notion of attraction is replaced with this notion of mere coalescence. I begin by outlining how blood is made from food. I then argue that an understanding of health and disease compels us to read Plato as if he were an atomist and to abandon the popular scholarly interpretations according to which the elements attract each other.

The editors have put together an interesting and important collection of twelve essays that trace the development of explanations of the human body that appeal to machines and other technological artefacts. Although the focus of the book is ancient authors, with the oldest being Homer and Pindar, the last essay reaches into the eighteenth century, at which point there are no longer mere analogies between human bodies and machines but a conception of the human body as something mechanized. The essays (...) are put together in such a way that emphasizes the early-modern conception as the terminus of the ancient mode of inquiry. (shrink)

In this paper, I argue that Bryson’s Oikonomikos is a fascinating example of the oikonomia genre in several different respects. Although the problematic transmission of this Neopythagorean text makes studying it a challenge, such effort is well-rewarded with an elaborate argument which paints the human bodily constitution, the central bodily functions and oikonomic activities as intrinsically linked. Focusing on Bryson’s argument which roots oikonomic behaviour in human biology, I explore the underlying conceptualisation of human nature and contextualise it within relevant (...) philosophical and scientific traditions.

What is Leucippus and Democritus’ theory of the beginning of life? How, if at all, did Leucippus and Democritus distinguish different kinds of living things? These questions are challenging in part because these Atomists claim that all living beings – including plants – have a share of reason and understanding. We answer these questions by examining the extant evidence concerning their views on embryology, the soul and respiration, and sense perception, thereby giving an overview of life and lifeforms in early (...) Greek atomism. We show, first, that the generation of all living beings happens through the combining of miniature copies of their parents’ atomic structures. Second, we argue that the Atomists take respiration to mark the beginning of life. Yet they do not consider respiration nor being ensouled to distinguish humans, animals, and plants from each other. Finally, because Leucippus and Democritus make little distinction between sense perception and thought, these too cannot sharply distinguish between different kinds of living beings. We conclude that Leucippus and Democritus advocated a less anthropocentric and more holistic view of the cosmos. (shrink)

This book assembles an international team of scholars to move forward the study of Plato’s conception of time, to find fresh insights for interpreting his cosmology, and to reimagine the Platonic tradition.

Models are of central importance in many scientific contexts. The centrality of models such as inflationary models in cosmology, general-circulation models of the global climate, the double-helix model of DNA, evolutionary models in biology, agent-based models in the social sciences, and general-equilibrium models of markets in their respective domains is a case in point (the Other Internet Resources section at the end of this entry contains links to online resources that discuss these models). Scientists spend significant amounts of time building, (...) testing, comparing, and revising models, and much journal space is dedicated to interpreting and discussing the implications of models. In short, models are one of the principal instruments of modern science. (shrink)

Metaphors play a crucial role in the understanding of science. Since antiquity, metaphors have been used in technical texts to describe structures unknown or unnamed; besides establishing a terminology of science, metaphors are also important for the expression of concepts. However, a concise terminology to classify metaphors in the language of science has not been established yet. But in the context of studying the history of a science and its concepts, a precise typology of metaphors can be helpful. Metaphors have (...) a lot in common with models in science, as has been observed already. In this paper, therefore, I suggest a typology of metaphor in ancient science to fill this terminological gap by using concepts applied to the classification of models in science, as coined by Rom Harré. I propose to differentiate between homeoconceptual metaphors and paraconceptual metaphors. Furthermore, functional and structural aspects of metaphors in ancient science are taken into account. Case studies from ancient texts displaying metaphors in ancient science are presented and classified following the outlined typology of metaphors. (shrink)

In the last two centuries, a better understanding of nature and significant advances in science and technology have led to the emergence of new and exciting ideas and approaches. Almost all of them are known as the product of contemporary science. Ideas such as evolution in biology, the ideas about the beginning of the universe (models based on the existence of a starting point for the universe or otherwise), and the idea of parallel worlds in physics. Although these ideas have (...) flourished in the context of modern science, they contain important philosophical backgrounds and as a result, have some important philosophical consequences. In this article, a historical review of the writings and works of Ibn Sina shows that each of these ideas has been presented similarly since ancient times in natural philosophy. Therefore, their position is more philosophical than scientific. Using these theories without considering their metaphysical and non-experimental assumptions will lead to misconceptions. Many of the challenges between science and religion stem from not considering the limits of empirical science and a lack of attention to the metaphysical assumptions of scientific theories. In this article, we will explain Ibn Sina's reasons for or against these theories as one of the first people to explicitly examine the scientific and philosophical aspects of these theories. Ibn Sina's scientific accuracy and admirable scientific spirit can be enlightening for contemporary scholars. (shrink)

Pathways into the Study of Ancient Sciences: Selected Essays. By David Pingree. Edited by Isabelle Pingree and John M. Steele. Transactions of the American Philosophical Society, vol. 104, pt. 3. Philadelphia: American Philosophical Society Press, 2014. Pp. xxii + 503.

On propose ici de clarifier ce qu’Anaximandre entendait par « le divin » et ce qu’il appelait des « dieux ». À partir d’une réévaluation des sources anciennes, on soutient que cette enquête peut aider à comprendre son modèle cosmologique et le problème des cataclysmes dans son système. Trois hypothèses sont avancées à cette fin : [i] que dans Physique, III, 4, 203b3 15, le syntagme τὸ ἄπειρον renvoie à une notion concrète de substrat infini ; [ii] que dans ce (...) même passage, Aristote n’a probablement pas attribué aux philosophes de la nature – y compris Anaximandre – la thèse selon laquelle τὸ ἄπειρον est divin, mais plutôt la thèse selon laquelle ils comprennent le divin comme étant immortel et impérissable ; [iii] qu’Anaximandre, en supposant que « les astres célestes » sont des dieux, admettrait qu’ils naissent mais ne se détruisent pas – ce qui réfuterait l’idée d’un cataclysme universel chez lui. En conclusion, l’étude discute en quoi consisterait la gouvernance cosmique de τὸ ἄπειρον dans un univers divisé en trois niveaux et propose que cette gouvernance viendrait du fait que τὸ ἄπειρον possède un mouvement éternel.

In antiquity living beings are inextricably linked to the cosmos as a whole. Ancient biology and cosmology depend upon one another and therefore a complete understanding of one requires a full account of the other. This volume addresses many philosophical issues that arise from this double relation. Does the cosmos have a soul of its own? Why? Is either of these two disciplines more basic than the other, or are they at the same explanatory level? What is the relationship between (...) living things and the cosmos as a whole? If the cosmos is an animate intelligent being, what is the nature of its thoughts and actions? How do these relate to our own thoughts and actions? Do they pose a threat to our autonomy as subjects and agents? And what is the place of zoogony in cosmogony? A distinguished international team of contributors provides original essays discussing these questions. (shrink)

This dissertation is about the early history of the concept of nature (φύσις or φυή/φυά) in Greek poetry and philosophy, and the significance of certain metaphors for that history, especially ones relating to plants (φυτά). The derivation of φύσις and φυή/φυά from the verb φύω/φύομαι (“grow,” but also “come to be”), which is likewise the source of φυτόν (“plant”), continues to nourish arguments about the historical role of the vegetal paradigm in the development of the Greek concept of nature. The (...) recent and widespread renewal of interest in nature and vegetation, in early Greek literature and innumerable other contexts, warrants a fresh assessment of the evidence, both with regard to the precise concepts of nature operating in the different corpora, and with regard to the precise significance of the vegetal metaphors. This dissertation focuses on two corpora, belonging to the fifth-century poets Pindar and Empedocles. In an era of conceptual revolutions and intense renewal and experimentation with metaphors in poetry and other discourse, both of these poets became famous for their metaphors as well as for their concepts of nature (for which Pindar uses both φύσις and φυά, Empedocles only φύσις). Novel analyses of their conceptualization of nature in Chapters 1 and 3 are paired with assessments in Chapters 2 and 4 of the significance of their plant metaphors, such as Pindar’s “fruit of the mind” and Empedocles’ elemental “roots.” Although it is commonly asserted that their vegetal imagery implies a concept of a universal Nature, it has been shown that their (and their contemporaries’) concepts of φύσις and φυά were limited to concrete individuals or groups; moreover, this dissertation argues, against the scholarly consensus, that both authors consistently use φύσις (and Pindar also φυά) to designate the “nature” or hypostatized collection of innate characteristics of an individual or group. One of the general tasks therefore of this dissertation is to show how vegetal metaphors bear on the explicit conceptualization of φύσις or φυά while also showing how certain metaphors prefigure the concept’s later history. Drawing on work in historical poetics, historical semantics, the history of concepts, and the history and theory of metaphors, this dissertation examines how the emerging concept of nature entered into original and powerful relationships with vegetal metaphors in the poetry of Pindar and Empedocles.

This volume explores the versatility of the concept of pneuma in philosophical and medical theories in the wake of Aristotle’s physics. It offers fourteen separate studies of how the concept of pneuma was used in a range of physical, physiological, psychological, cosmological and ethical inquiries. The focus is on individual thinkers or traditions and the specific questions they sought to address, including early Peripatetic sources, the Stoics, the major Hellenistic medical traditions, Galen, as well as Proclus in Late Antiquity and (...) John Zacharias Aktouarios in the early 14th century. Building on new scholarly approaches and on recent advancements in our understanding of Graeco-Roman philosophy and medicine, the volume prompts a profound re-evaluation of this fluid and adaptable, but crucially important, substance, in antiquity and beyond.

The Pneumatist school of medicine has the distinction of being the only medical school in antiquity named for a belief in a part of a human being. Unlike the Herophileans or the Asclepiadeans, their name does not pick out the founder of the school. Unlike the Dogmatists, Empiricists, or Methodists, their name does not pick out a specific approach to medicine. Instead, the name picks out a belief: the fact that pneuma is of paramount importance, both for explaining health and (...) disease, and for determining treatments for the healthy and sick. In this paper, we re-examine what our sources say about the pneuma of the Pneumatists in order to understand what these physicians thought it was and how it shaped their views on physiology, diagnosis and treatment.

This book provides a comprehensive overview of the key themes in Greek and Roman science, medicine, mathematics and technology. A distinguished team of specialists engage with topics including the role of observation and experiment, Presocratic natural philosophy, ancient creationism, and the special style of ancient Greek mathematical texts, while several chapters confront key questions in the philosophy of science such as the relationship between evidence and explanation. The volume will spark renewed discussion about the character of 'ancient' versus 'modern' science, (...) and will broaden readers' understanding of the rich traditions of ancient Greco-Roman natural philosophy, science, medicine and mathematics.

Relying upon a very close reading of all of the definitions given in Euclid’s Elements, I argue that this mathematical treatise contains a philosophical treatment of mathematical objects. Specifically, I show that Euclid draws elaborate metaphysical distinctions between substances and non-substantial attributes of substances, different kinds of substance, and different kinds of non-substance. While the general metaphysical theory adopted in the Elements resembles that of Aristotle in many respects, Euclid does not employ Aristotle’s terminology, or indeed, any philosophical terminology at (...) all. Instead, Euclid systematically uses different types of definition to distinguish between metaphysically different kinds of mathematical object. (shrink)

This volume is the first in English to provide a full, systematic investigation into Aristotle's criticisms of earlier Greek theories of the soul from the perspective of his theory of scientific explanation. Some interpreters of the De Anima have seen Aristotle's criticisms of Presocratic, Platonic, and other views about the soul as unfair or dialectical, but Jason W. Carter argues that Aristotle's criticisms are in fact a justified attempt to test the adequacy of earlier theories in terms of the theory (...) of scientific knowledge he advances in the Posterior Analytics. Carter proposes a new interpretation of Aristotle's confrontations with earlier psychology, showing how his reception of other Greek philosophers shaped his own hylomorphic psychology and led him to adopt a novel dualist theory of the soul–body relation. His book will be important for students and scholars of Aristotle, ancient Greek psychology, and the history of the mind–body problem. (shrink)

“Ancient DNA Research” is the practice of extracting, sequencing, and analyzing degraded DNA from dead organisms that are hundreds to thousands of years old. Today, many researchers are interested in adapting state-of-the-art molecular biological techniques and high-throughput sequencing technologies to optimize the recovery of DNA from fossils, then use it for studying evolutionary history. However, the recovery of DNA from fossils has also fueled the idea of resurrecting extinct species, especially as its emergence corresponded with the book and movie Jurassic (...) Park in the 1990s. In this paper, I use historical material, interviews with scientists, and philosophical literature to argue that the search for DNA from fossils can be characterized as a data-driven and celebrity-driven practice. Philosophers have recently argued the need to seriously consider the role of data-driven inquiry in the sciences, and likewise, this history highlights the need to seriously consider the role of celebrity in shaping the kind of research that gets pursued, funded, and ultimately completed. On this point, this history highlights that the traditional philosophical and scientific distinctions between data-driven and hypothesis-driven research are not always useful for understanding the process and practice of science. Consequently, I argue that the celebrity status of a particular research practice can be considered as a “serious epistemic strategy” that researchers, as well as editors and funders, employ when making choices about their research and publication processes. This interplay between celebrity and methodology matters for the epistemology of science. (shrink)

Chapter 1st of the book. This chapter explores the fundamental ambiguity of the concept of plasticity – between openness and determination, change and stabilization of forms. This pluralism of meanings is used to unpack different instantiations of corporeal plasticity across various epochs, starting from ancient and early modern medicine, particularly humouralism. A genealogical approach displaces the notion that plasticity is a unitary phenomenon, coming in the abstract, and illuminates the unequal distribution of different forms of plasticities across social, gender, and (...) ethnic groups. Taking a longer view of the plastic body as a ubiquitous belief in traditions predating and coexisting with modern medicine will help contextualize the seeming radicalism of today’s turn to permeability and the exceptionalism of Western findings. By highlighting the complex biopolitical usages of plasticity in the past, the chapter warns against simplistic appropriations of the term in contemporary body/world configurations driven by findings in neuroscience, epigenetics and microbiomics.

What was science for the Orthodox Greek theologian of the nineteenth century? How did it feature in his (theologians were all men at the time) own work? This article is an attempt to describe the science and religion interactions by placing Greek Orthodox theologians of the nineteenth century in the center of the historical narrative, rather than treat them as occasional deuteragonists in the scientists’ historiography. The picture that emerges is far more complicated than one of antagonism, indifference, conflict, or (...) coexistence. Greek theologians saw themselves as scientists and treated theology as a positive, rational science. They developed strategies to delineate their disciplinary borders and safeguard their identity as expert scholars by harnessing their university and academic credentials. For that reason, they had to invoke famous German and other Western theologians, while ensuring that they were seen as true defenders of Orthodox Christianity. The idea of science was an integral part of this achievement. (shrink)

The _Physics_ is a foundational work of western philosophy, and the crucial one for understanding Aristotle's views on matter, form, essence, causation, movement, space, and time. This richly annotated, scrupulously accurate, and consistent translation makes it available to a contemporary English reader as no other does—in part because it fits together seamlessly with other closely associated works in the New Hackett Aristotle series, such as the _Metaphysics_, _De Anima_, and forthcoming _De Caelo_ and _On Coming to Be and Passing Away_. (...) Eventually the series will include all of Aristotle's works. Sequentially numbered endnotes provide the information most needed at each juncture, while a detailed Index of Terms indicates places where focused discussion of key notions occurs. An illuminating general Introduction describes the book that lies ahead, explaining what sort of work it is and what sorts of evidence it relies on. (shrink)

In 1988 the philosopher Gilles Deleuze remarked that throughout his career he had always been 'circling around' a concept of nature. Showing how Deleuze weaves original readings of Plato, the Stoics, Aristotle, and Epicurus into some of his most famous arguments about event, difference, and problem, Michael James Bennett argues that these interpretations of ancient Greek physics provide vital clues for understanding Deleuze's own conception of nature. -/- "Deleuze and Ancient Greek Physics" delves into the original Greek and Latin texts (...) and situates Deleuze's interpretations in relation to contemporary scholarship on ancient philosophy. It reveals that these readings are both more complex and controversial than they may at first appear. Generating both new critical analyses of Deleuze and an appreciation for his classical erudition, this book will be a valuable resource for anyone interested in ancient Greek philosophy, Deleuze's philosophical project, or his unique methodology in the history of philosophy.

Ekphrasis is familiar as a rhetorical tool for inducing enargeia, the vivid sense that a reader or listener is actually in the presence of the objects described. This book focuses on the ekphrastic techniques used in ancient Greek and Roman literature to describe technological artifacts. Since the literary discourse on technology extended beyond technical texts, this book explores 'technical ekphrasis' in a wide range of genres, including history, poetry, and philosophy as well as mechanical, scientific, and mathematical works. Technical authors (...) like Philo of Byzantium, Vitruvius, Hero of Alexandria, and Claudius Ptolemy are put into dialogue with close contemporaries in other genres, like Diodorus Siculus, Cicero, Ovid, and Aelius Theon. The treatment of 'technical ekphrasis' here covers the techniques of description, the interaction of verbal and visual elements, the role of instructions, and the balance between describing the artifact's material qualities and the other bodies of knowledge it evokes.

Otto Neugebauer’s early academic career was marked by a series of transitions. His interests shifted from physics to mathematics, and finally to the history of ancient mathematics and exact sciences. Yet even from his early years in Graz, Neugebauer was strongly attracted to the mathematical culture of Göttingen. When he arrived there in 1922, he quickly established a strong personal friendship with Richard Courant, the newly appointed Director of the Mathematics Institute. Neugebauer and Courant worked together closely up until 1933, (...) when the Nazi government decimated the Göttingen scientific community. In this essay, Neugebauer’s historical work and his vision for a new approach to the study of the exact sciences are viewed through the prism of these events. By so doing, one can easily appreciate how Neugebauer’s scholarship reflects the ideals he and Courant shared as leading representatives of the Göttingen mathematical tradition. (shrink)
