Levi ben Gerson (1288–1344) was a medieval astronomer who responded in an unusual way to the Ptolemaic tradition. He significantly modified Ptolemy’s lunar and planetary theories, in part by appealing to physical reasoning. Moreover, he depended on his own observations, with instruments he invented, rather than on observations he found in literary sources. As a result of his close attention to the variation in apparent planetary sizes, a subject entirely absent from the Almagest, he discovered a new phenomenon of (...) Mars and noticed a serious flaw in Ptolemy’s treatment of the Moon. (shrink)

This dissertation is about human knowledge of reality. In particular, it argues that scientific knowledge is bounded by historically available instruments and theories; nevertheless, the use of several independent instruments and theories can provide access to the persistent potentialities of reality. The replicability of scientific observations and experiments allows us to obtain explorable evidence of robust entities and properties. The dissertation includes seven chapters. It also studies three cases – namely, Higgs bosons and hypothetical Ϝ-particles (section 2.4), the Ptolemaic (...) and Kepler model of the planets (section 6.7), and the special theory of relativity (chapter 7). -/- Chapter 1 is the introduction of the dissertation. Chapter 2 clarifies the notion of the real on the basis of two concepts: persistence and resistance. These concepts enable me to explain my ontological belief in the real potentialities of human-independent things and the implications of this view for the perceptual and epistemological levels of discussion. On the basis of the concept of “overlapping perspectives”, chapter 3 argues that entity realism and perspectivism are complementary. That is, an entity that manifests itself through several experimental/observational methods is something real, but our knowledge of its nature is perspectival. Critically studying the recent views of entity realism, chapter 4 extends the discussion of entity realism and provides a criterion for the reality of property tokens. Chapter 5, in contrast, develops the perspectival aspects of my view on the basis of the phenomenological-hermeneutical approaches to the philosophy of science. This chapter also elaborates my view of empirical evidence, as briefly expressed in sections 2.5 and 4.5. Chapter 6 concerns diachronic theoretical perspectives. It first explains my view of progress, according to which current perspectives are broader than past ones. Second, it argues that the successful explanations and predictions of abandoned theories can be accounted for from our currently acceptable perspectives. The case study of Ptolemaic astronomy supports the argument of this chapter. Chapter 7 serves as the conclusion of the dissertation by applying the central themes of the previous chapters to the case study of special relativity theory. I interpret frame-dependent properties, such as length and time duration, and the constancy of the speed of light according to realist perspectivism. (shrink)

The Earth is positioned at the center of the universe in the Ptolemaic model of the universe. The center of the Earth is at the same time the center of the universe in this model. This system, which was constructed according to Aristotelian physics, was accepted as the prevailing theory up to the adoption of the heliocentric universal model in the 16th century. The Earth was at the same time assumed to be completely stationary in the geocentric theory. Movement (...) around its own axis or around another celestial body was out of the question for it. In Antiquity and the Middle Ages when observational instruments like the telescope were not yet in use, this theory was seen to be rationally based on data obtained directly from the senses. In this context, various justifications had been provided about the world being stationary and existing at the center. Representatives from the Peripatetic philosophy in the Muslim world also were seen to accept the geocentric model. In The Book of Healing, Ibn Sīnā (d. 1038 CE) subjected the proofs that had come to him about the Earth being stationary by distinguishing an independent chapter. The 14th century follower of Ibn Sīnā’s philosophy, Najm al-Dīn al-Kātibī addressed this topic in Ḥikmat al-‘ain, and the work’s principle commentators also commented on his assessments. This study will address Ibn Sīnā’s assessments on the Earth being stationary in the geocentric model of the universe and will discuss the reflections of these assessments in Ḥikmat al-‘ain as an Avicennan text.

It is argued that the origins of modern science can be revealed due to joint account of external and internal factors. The author tries to keep it in mind applying his scientific revolution model according to which the growth of knowledge consists in interaction, interpenetration and even unification of different scientific research programmes. Hence the Copernican Revolution as a matter of fact consisted in realization and elimination of the gap between the mathematical astronomy and Aristotelian qualitative physics in (...) class='Hi'>Ptolemaic cosmology. Yet the very realization of the contradictions became possible because at the first stages European science was a result of Christian Weltanschaugung evolution with its gradual elimination of pagan components. Key words: modern European science, Christian Weltanschaugung. (shrink)

Astronomy and religion have long been intertwined with their interactions resembling a symbiotic relationship since prehistoric times. Building on existing archaeological research, this study asks: do the interactions between astronomy and religion, beginning from prehistory, form a distinct religious tradition? Prior research exploring the prehistoric origins of religion has unearthed evidence suggesting the influence of star worship and night sky observation in the development of religious sects, beliefs and practices. However, there does not yet exist a historiography dedicated (...) to outlining why astronomy and religion mutually developed, nor has there been a proposal set forth asserting that these interactions constitute a religious tradition; proposed herein as the Astronic tradition, or Astronicism. This paper pursues the objective of arguing for the Astronic tradition to be treated, firstly, as a distinct religious tradition and secondly, as the oldest archaeologically-verifiable religious tradition. To achieve this, the study will adopt a multidisciplinary approach involving archaeology, anthropology, geography, psychology, mythology, archaeoastronomy and comparative religion. After proposing six characteristics inherent to a religious tradition, the paper will assemble a historiography for astronomical religion. As a consequence of the main objective, this study also asserts that astronomical religion, most likely astrolatry, has its origins in the Upper Palaeolithic period of the Stone Age based on specimens from the archaeological record. The assertion is made that astrolatry is the original religion and fulfils the Urreligion theory. To end, the proposed characteristics of a religious tradition will be applied to Astronicism to ultimately determine whether it is a valid tradition that can stand alongside the established Abrahamic, Dharmic and Taoic traditions.

The philosophy of historical sciences investigates their distinct objects of study, epistemic challenges, and methodological solutions. Rethinking astronomy in this light offers a contribution. First, the methodology of historical sciences adds to a more adequate description of how astronomers study and utilize token events. Second, astronomy faces a typical difficulty in identifying traces of some past events and has developed a delicate solution. This enriches the idea of trace and suggests a methodology that relies on iterations between data-driven (...) approaches and theory-driven approaches, together with the cross-validation between multiple relevant historical events or datasets.

For centuries the case of Galileo Galilei has been the cornerstone of every major argument against the church and its supposedly unscientific dogmatism. The church seems to have condemned Galileo for his heresies, just because it couldn’t and wouldn’t handle the truth. Galileo was a hero of science wrongfully accused and now – at last – everyone knows that. But is that true? This paper tries to examine the case from the point of modern physics and the conclusions drawn are (...) startling. It seems that contemporary church was too haste into condemning itself. The evidence provided by Galileo to support the heliocentric system do not even pass simple scrutiny, while modern physics has ruled for a long time now against both heliocentric and geocentric models as depictions of the “truth”. As Einstein eloquently said, the debate about which system is chosen is void of any meaning from a physics’ point of view. At the end, the selection of the center is more a matter of choice rather than a matter of ‘truth’ of any kind. And this choice is driven by specific philosophical axioms penetrating astronomy for hundreds of years now. From Galileo to Hubble, the Copernican principle has been slowly transformed to a dogma followed by all mainstream astronomers. It is time to challenge our dogmatic adherence to the anti-humanism idea that we are insignificant in the cosmos and start making true honest science again, as Copernicus once postulated. (shrink)

ABSTRACT This article interprets a recently recovered manuscript, Tratado de astronomía y la reformaçión del tiempo, composed by Antonio Sánchez in New Granada c.1696, in the context of the Spanish and Renaissance cosmographies. Sánchez’s Tratado proposes a spherical astronomy, in which celestial bodies – including comets — move in orbs containing pyramidal knots that explain the changing speed observed in the motion of planets. From this astronomy and following the peninsular style of repertorios, Sánchez derives two major conclusions: (...) the corrected length of the solar year and a revised birth date of Jesus. Taking as center of reference Vélez, where Sánchez was based, these claims led to conclusions in domains ranging from calendric astronomy to eschatology, including the incorporation of the indigenous peoples into salvation narrative and a demonstration of the arrangement of the celestial orbs at the Last Judgment. Sánchez’s Tratado constitutes an expansion of the Spanish mathematical cosmography that sheds light on the production of knowledge in the Spanish-American world and, at the same time, provides elements to reassess our understanding of the global circulation of Renaissance and early modern ideas.

Originating in the field of biology, the concept of the hybrid has proved to be influential and effective in historical studies, too. Until now, however, the idea of hybrid knowledge has not been fully explored in the historiography of pre-modern science. This article examines the history of pre-Copernican astronomy and focuses on three case studies—Alexandria in the second century CE; Baghdad in the ninth century; and Constantinople in the fourteenth century—in which hybridization played a crucial role in the development (...) of astronomical knowledge and in philosophical controversies about the status of astronomy and astrology in scholarly and/or institutional settings. By establishing a comparative framework, this analysis of hybrid knowledge highlights different facets of hybridization and shows how processes of hybridization shaped scientific controversies.

Observational astronomy is plagued with selection effects that must be taken into account when interpreting data from astronomical surveys. Because of the physical limitations of observing time and instrument sensitivity, datasets are rarely complete. However, determining specifically what is missing from any sample is not always straightforward. For example, there are always more faint objects (such as galaxies) than bright ones in any brightness-limited sample, but faint objects may not be of the same kind as bright ones. Assuming they (...) are can lead to mischaracterizing the population of objects near the boundary of what can be detected. Similarly, starting with nearby objects that can be well observed and assuming that objects much farther away (and sampled from a younger universe) are of the same kind can lead us astray. Demographic models of galaxy populations can be used as inputs to observing system simulations to create “mock” catalogues that can be used to characterize and account for multiple, interacting selection effects. The use of simulations for this purpose is common practice in astronomy, and blurs the line between observations and simulations; the observational data cannot be interpreted independent of the simulations. We will describe this methodology and argue that astrophysicists have developed effective ways to establish the reliability of simulation-dependent observational programs. The reliability depends on how well the physical and demographic properties of the simulated population can be constrained through independent observations. We also identify a new challenge raised by the use of simulations, which we call the “problem of uncomputed alternatives.” Sometimes the simulations themselves create unintended selection effects when the limits of what can be simulated lead astronomers to only consider a limited space of alternative proposals.

Celestial bodies have long been a source of religious objectification and this article aims to convey the origin of the relationship between human religious belief and observations of the night sky. The academic search for the origin of religion commenced in the early nineteenth century and since then the debate of whether animism or pre-animism is the original religion has dominated this field. Until now, no unified theory has acknowledged the influence of primitive astronomy on the origin of religion. (...) However, the theory of Astronicism supports the pre-animist hypothesis by proposing that early modern humans of the Upper Palaeolithic made simple associations between celestial bodies and their apparent capacity to determine human survival. This article asserts that these associations led to celestial deification long before humans animated astronomical phenomena with spirits. Archaeological specimens from Europe and beyond including astral rock art, cup marks and engravings are used in this article to assert that astrolatry and astromancy were crucial to the development of religion.

Serial Endosymbiosis Theory, or SET, was conceived and developed by Lynn Margulis, to explain the greatest discontinuity in the history of life, the origin of eukaryotic cells. Some predictions of SET, namely the origin of mitochondria and chloroplasts, withstood the test of the most recent evidence from a variety of disciplines including phylogenetics, biochemistry, and cell biology. Even though some other predictions fared less well, SET remains a seminal theory in biology. In this paper, I focus on two aspects of (...) SET. First, using the concept of "universal symbiogenesis”, developed by Freeman Dyson to search for commonalities in astronomy and biology, I propose that SET can be extended beyond eukaryogenesis. The extension refers to the possibility that even prokaryotic organisms, themselves subject to the process of symbiogenesis in SET, could have emerged symbiotically. Second, I contrast a recent “viral eukaryogenesis” hypothesis, according to which the nucleus evolved from a complex DNA virus, with a view closer to SET, according to which the nucleus evolved through the interplay of the archaeal host, the eubacterial symbiont, and a non-LTR transposon, or telomerase. Viruses joined in later, through the process of viral endogenization, to shape eukaryotic chromosomes in the process of karyotype evolution. These two proposals based on SET are a testament to its longevity as a scientific theory. (shrink)

Dark matter in astrophysics offers a rare treat for philosophers of science. When they look at the contemporary science of dark matter, they see reports of a widely accepted theoretical posit indispensable to our best theories and models but without an accepted experimental confirmation of its existence. Nearly all astrophysicists and cosmologists believe that dark matter exists and makes up approximately a quarter of the mass-energy content of the universe. However, they seem to know almost nothing about its nature, cannot (...) directly observe it, and have been unable to detect the products of any interactions with any of the candidate dark matter particles. This project addresses the apparent tension between the impressive knowledge taken to have been obtained in contemporary sciences of the cosmos and the methodological and theoretical limitations in obtaining such knowledge. To do so, this dissertation investigates the ways in which astronomers and astrophysicists are making progress by looking more closely at their experimental practices and actual theoretical commitments. More specifically, the goal is to determine how this bears on longstanding philosophical questions of scientific realism and the nature of scientific experimentation. Ultimately, I argue that astronomers do conduct traditional, interventionist experiments and that we can be realists about dark matter. These two views offer a way of thinking differently about how scientists can and do obtain knowledge about inaccessible and unobservable targets systems. -/- . (shrink)

The attempt to narrow the general discourse of the problem of error and to focus it on the specific problem of experimental error may be approached from different directions. One possibility is to establish a focusing process from the standpoint of history; such an approach requires a careful scrutiny of the history of science with a view to identifying the juncture when the problem of experimental error was properly understood and accounted for. In a study of this kind one would (...) have to examine the evolution of the method of experimentation and related topics so that clear criteria would underlie the analysis. (shrink)

The lunar Three-Body problem is a famously intractable problem of Newtonian mechanics. The demand for accurate predictions of lunar motion led to practical approximate solutions of great complexity, constituted by trigonometric series with hundreds of terms. Such considerations meant there was demand for high speed machine computation from astronomers during the earliest stages of computer development. One early innovator in this regard was Wallace J. Eckert, a Columbia University professor of astronomer and IBM researcher. His work illustrates some interesting features (...) of the interaction between computers and astronomy. (shrink)

The dóxa is a major aspect of Parmenides’ “scientific” commitment, as evidenced by studies of its discoveries in various fields of knowledge. Among them in astronomy. However, these studies have ended up identifying a scientific plan separate from the mythicalreligious and philosophical one of the first part. This survey explores the possibility of reconsidering the presence in the Parmenides’ dóxa of ontology and theology. It does so by proposing the hypothesis that the proem contains among the multiple semantic-linguistic layers (...) the mythopoeic presentation of the astronomical theorem of the identity of Eos and Hesperus, with the intent of showing, from the very beginning and in the most authoritative language for his audience, the alḗtheia of «being» on the divine stage of the celestial sphere. In our reading, therefore, the deities that enter the scene give life to a firmament that interconnects every cosmic dimension with each other and leads the one who knows (the εἰδότα φῶτα; B1, 3) – he knows that πᾶν πλέον ἐστὶν ὁμοῦ φάεος καὶ νυκτὸς because ἐπεὶ οὐδετέρωι μέτα μηδέν (B9, 3-4) – on the other side of the sky, in the presence of the theá that will reveal to him the meaning of everything.

Since the formal academic study of religion commenced in the 19th century with scholars like Friedrich Max Müller (Abraham & Hancock, 2020), religions have been neatly categorised into three traditions; Abrahamic, Dharmic and Taoic (NowThis World, 2015). However, ignited by my personal interest in both astronomy and religion, I have realised that a fourth tradition exists that has not yet been formally accepted into academic nomenclature. This unestablished tradition of religion is characterised by the observation and worship of, devotion (...) to, and divination by, the stars (Irvin & Rutajit, 2006). To acknowledge the existence of an entire religious tradition will clarify and affirm the central role of astronomy in the development of world religion, a role that has been undermined by established religions throughout the centuries (Martínez, 2019, p372-375; Valentinuzzi, 2019, p23-27). As such, these religious institutions have acted as knowledge gatekeepers. However, following on from the legacy of the Enlightenment, the freedoms it brought to scholarship and the development of the academic study of religion in the 19th and 20th centuries, now is perhaps the best time to propose the validity of a religious tradition based on astronomy. In turn, I propose that the historical background of astronomy and religion, particularly focusing on their prehistoric origins, need to be explored. Firstly, I feel that it is important to demonstrate creativity and my passion for this research area by introducing this collection of religions as the Astronic tradition. Proving the validity of this tradition will act as the nucleus of my dissertation, but explaining the reasons for studying this area will further illuminate the subject. My focus on this area was initially sparked by my interest in astronomy and religion, particularly due to my own personal beliefs. After investigating the current body of literature, there is a lack of specificity to the history of astronomy and religion, particularly from religious scholars. At present, the scholarship in this area of research is certainly dispersed across disciplines, hence the importance of my holistic approach to bring these dispersed works together when and where they become relevant. I also have ambitions that my work will ignite scholars of religion to research this area in the future to provide further testament to the Astronic tradition’s historicity. Furthermore, another macro-level reason for my choosing of this topic involves the ever-growing role of space exploration in society lead by entrepreneurs like Elon Musk, thus highlighting the need for greater comprehension of humanity’s religious connections to the stars. This involves establishing a coherent history for humanity’s religio-philosophical interactions with outer space and how the future of humanity in space will alter the religious landscape. Having now understood my rationale, it is essential that I explain how I intend to achieve my aims. (shrink)

The history of the science of the stars (astronomy and astrology) in fourteenth-century Byzantium is significantly intertwined with the implications of theological and philosophical controversies. A less-explored astronomical text authored by the fourteenth-century Byzantine scholar Theorodos Meliteniotes (ca. 1320–1393 CE) provides new historical factors toward a historiography of the differences between scientific and theological discourses, their development in the transition to early modern times, and the different historical developments of science in the worlds of the Eastern and Western Churches.

This article would appeal to people interested in new ideas in sciences like physics, astronomy and mathematics that are not presented in a formal manner. -/- Biologists would also find the paragraphs about evolution interesting. I was afraid they'd think my ideas were a bit "out there". But I sent a short email about them last year to a London biologist who wrote an article for the journal Nature. She replied that it was "very interesting". -/- The world is (...) fascinated by electronics. Computer scientists, as well as computer buyers, would be intrigued by the fundamental role given to human electronics in creation of the universe. This obviously can only be done if time travel to the past is possible. I explain in scientific terms how it could be done (the world is also fascinated by the prospect of time travel). -/- My ideas on trips through time grew from the related topic of interstellar, and even intergalactic, travel (and those ideas are inspired by an electrical-engineering experiment at Yale University in 2009). After the ideas on time travel came the realization that this technology could be used to totally eliminate the problems of muscle and bone weakness, radiation exposure etc associated with a lengthy journey to Mars. -/- The exquisitely ordered cosmos proposed would have great appeal to religion and philosophy. Dealing as it does with time that does not exclusively operate in a straight line, the book could not only present a new view of evolution (present theory assumes time is always a straight line from past to future). Nonlinear time might also give religionists a new concept of who God is. This could possibly be that of humans from the remote future who are quantum entangled with all past, present and future states of the whole - infinite and eternal - universe; and thus have all God's powers. Such infinite power could be pantheistic but would naturally include the ability to manifest as an individual. (I know this article is very far removed from what is traditionally considered scientific. Just remember: science is the search for knowledge of how this universe works, and that search must be pursued wherever it leads - even if it leads into traditionally nonscientific areas such as religion.) -/- Finally - if we're entangled with the whole universe, we'd have to be entangled with each other. On a mundane level, this gives us extrasensory and telekinetic abilities. On a higher level, it eliminates crime and war and domestic violence since people don't normally desire to harm themselves in any way. (shrink)

A scientific theory is successful, according to Stanford (2000), because it is suficiently observationally similar to its corresponding true theory. The Ptolemaic theory, for example, is successful because it is sufficiently similar to the Copernican theory at the observational level. The suggestion meets the scientific realists' request to explain the success of science without committing to the (approximate) truth of successful scientific theories. I argue that Stanford's proposal has a conceptual flaw. A conceptually sound explanation, I claim, respects the (...) ontological order between properties. A dependent property is to be explained in terms of its underlying property, not the other way around. The applicability of this point goes well beyond the realm of the debate between scientific realists and antirealists. Any philosophers should keep the point in mind when they attempt to give an explanation of a property in their field whatever it may be. (shrink)

● Much more relevant than the simplicity or complexity of a method of measuring the houses is whether such a division remains true to the physics of the sky (i.e. whether it makes any sense at all). ● Because astrology has no central institution to decide what is valid and what is not, we believe that the least astrologists should do is to respect the truths confirmed by science. Physics teaches that we cannot separate time from space or space from (...) time, for they stand in an unbreakable or indissoluble relationship which we call continuum , a plane made up of four dimensions (i.e. the three of space plus the one of time) regarded as spacetime, and that time is not absolute but relative (dependent on frames of reference). ● Astrology — which is not horoscopism but one of the consequences of physics — appeals to different methods of measuring segments of our horizon known as houses, sectors, or regions and has classified them into space-based measurements and time-based measurements (according to which of the two concepts decides the subdivision of the diurnal arc) , but said classification is impertinent according to the reality that governs us. ● One that can be confirmed to be compatible with our reality is to be employed at all times for all types of charts, that is to say, one that is truly or essentially spacetime-based without, at the same time, presenting any of the errors characteristic of other house systems . We will see that only one will be compatible with relativity, for while the others would have us believe that time is absolute, the Placidus method of house measurement will show us that it is relative. ● The difference lies in the ability of a method to recognise the different ascensional times of not only the twelve segments of our ecliptic at different latitudes but also of each degree of said circumference simultaneously and uninterruptedly, that is, temporally simultaneously and spatially uninterruptedly during their trajectories from the horizon (ASC) to the midheaven (MC). We concluded, based on the house cusp analysis, that only the Placidean formula can carry out this promise, that is, make it possible to measure the lengths of time under said conditions. ● While the Alcabitius and Koch measurements of time assign fictional speeds — i.e. times of oblique ascension — to all degrees contained between the horizon (ASC) and the midheaven (MC), Placidus takes care to measure the speeds or true times for all. The measurement most Newtonian of all the methods of house division, Regiomontanus, in turn, clings to space at the expense of time, the reason for which it cannot reflect the true positions of the planets in spacetime (ignores the relationship between space and time). ● During the demonstrational process, we take the opportunity of pointing out that velocity (special relativity) and gravity (general relativity) do not constitute the only — two — primary forms of time dilation. The tilt of a reference frame relative to another (that of Earth relative to the plane of our ecliptic, although velocity remains a variable, whereas gravity, in turn, a possibility we will explore in the appendices) constitutes the third form. ● We encourage any physicist and/or astronomer to corroborate our observations with their own tools. For our part, we have employed the astrological/astronomical software Solar Fire Gold, although the astrographs come from the astrological/astronomical software Janus. (shrink)

In this paper I will investigate the identity of the daímōn introduced by Parmenides in B12, 3 DK, the deity “who steers all things”. The importance of this deity is not adequately reflected in ancient doxography but in recent decades many scholars have reconsidered its role. I argue that in Parmenides’ poem this daímōn may play a relevant role in connecting the theological, ontological and cosmological planes. My purpose is to provide enough arguments for the hypothesis that the daímōn may (...) be the same goddess, Themis, who in the proem (B1, 28) is paired with Dike as a guide for Parmenides to the theá who will reveal to him the truth of tò eón, and in the part of the poem called alḗtheia (B8, 32) is echoed as the divine personification of the thémis of tò eón itself. I will examine the different identities and attributes found in the accounts on Parmenides’ daímōn and will compare them with the identities and attributes that the mythological tradition assigns to the goddess Themis.

Scientists often diverge widely when choosing between research programs. This can seem to be rooted in disagreements about which of several theories, competing to address shared questions or phenomena, is currently the most epistemically or explanatorily valuable—i.e. most successful. But many such cases are actually more directly rooted in differing judgments of pursuit-worthiness, concerning which theory will be best down the line, or which addresses the most significant data or questions. Using case studies from 16th-century astronomy and 20th-century geology (...) and biology, I argue that divergent theory choice is thus often driven by considerations of scientific process, even where direct epistemic or explanatory evaluation of its final products appears more relevant. Broadly following Kuhn’s analysis of theoretical virtues, I suggest that widely shared criteria for pursuit-worthiness function as imprecise, mutually-conflicting values. However, even Kuhn and others sensitive to pragmatic dimensions of theory ‘acceptance’, including the virtue of fruitfulness, still commonly understate the role of pursuit-worthiness—especially by exaggerating the impact of more present-oriented virtues, or failing to stress how ‘competing’ theories excel at addressing different questions or data. This framework clarifies the nature of the choice and competition involved in theory choice, and the role of alternative theoretical virtues. (shrink)

I confront Feyerabend's position and critical rationalism in order to have a foundation or starting point for my (historical) investigation. The main difference of his position towards falsificationism is the belief that different theories cannot be discussed rationally. Feyerabend is convinced that Galilei's observations with the telescope in the historical context of the Copernican revolution supports his criticism. In particular, he argues that the Copernican theory was supported by deficient hypotheses, and falsifications were disposed by ad hoc hypotheses and propaganda. (...) Furthermore, he claims that his philosophy of science reconstructs Galilei's defence of the Copernican theory. He introduces a central principle of his position (the principle of tenacity) in order to justify a research strategy of not eliminating falsified theories. He tries to show that the tenacious defence of a theory corresponds to Galilei's defence of the Copernican theory. Remarkably, Feyerabend's approach to explain the development of science earns an important support from his interpretation of Galilei's observations. On this basis I give a falsificationist interpretation of Galilei's observations with the telescope, and oppose this interpretation to Feyerabend's. From a falsificationist perspective, auxiliary hypotheses compete during the Copernican revolution which can (with some effort) be critically discussed. Then I analyse the historical case in order to test Feyerabend's interpretation of the Copernican revolution. Inter alias I investigate thoroughly whether Galilei, as Feyerabend claims, immunised falsifications of the Copernican theory by the introduction of ad hoc hypotheses. The investigation considers Galilei's explanation of Venus' phases, his establishment of the irradiation hypothesis, the explanation of the telescope's functionality, and the role of the reproducibility of the observations with the telescope. Finally I provide a rational reconstruction of Galilei's falsification of the Ptolemaic theory. The formalisation shows that Galilei was not a cautious critical rationalist, but a very confident scientist using the method of falsification. (shrink)

SUMMARY. The works of Alexander of Aphrodisias were written a few decades after the publication of the most successful -astrology hand- book in antiquity, Ptolemy's Tetrabiblos Syntaxis, which attempts to naturalize astrology, i.e. to make it agree with Aristotelian theory of science. A comparison of the doctrines between the Tetrabiblos and some passages of Alexander'p works on fate demostrates a noteworthy con¬vergere of the two scholars, and probably a dependence of the lasi great greek Aristotle's exegete on the theories of (...) Ptolemaic astrology, at least in reference to three points: theory of fate; justification of de- vining as a technical and naturai conjecture about man's fate; ana¬lysis of the stars' influence on the sublunary world in physical and phi¬losophical terms.

The year 2012 marks the fiftieth anniversary of the original publication of Thomas Kuhn’s famous book, The Structure of Scientific Revolutions. Kuhn, who taught at Berkeley, Princeton and MIT following studies in physics at Harvard, was a historian of science whose ideas have had a major impact on the philosophy of science. Now in its third edition, Structure has had a lasting influence on our thinking about science. After fifty years, Kuhn’s ideas show signs of wear. But they continue to (...) shape our “image of science”, to echo Kuhn’s own turn of phrase in the opening lines of Structure. The core idea of Structure is that scientific research is based on underlying theoretical structures which provide a framework for research in a field for a sustained period of time. Kuhn’s name for these structures was paradigm. It is Kuhn’s use of the word that inserted ‘paradigm’ into the popular lexicon. His original use of the word was flexible. But he had two key points in mind. First, there is a set of beliefs about a domain of study, including generalizations and a model of how the domain is constituted, that is adopted as the basis for scientific practice in a scientific field at a time. Second, there are a number of important examples of exemplary scientific research which later scientists look back to as guiding inspiration for their own research. Examples include Copernican heliocentric astronomy, Lavoisier’s oxygen-based chemistry and Darwin’s theory of evolution by natural selection. All of these constituted paradigms for scientists working in these areas for a significant period of time, both in the sense of providing an overarching set of beliefs about the world and in the sense of providing examples of exemplary research.

The article presents two antagonistic views of reality, one coming from modern science and the other from flat-Earthers, to discuss the relationships between common-sense, science, and reality. The concrete fact under analysis refers to the solar system and the position of the earth in this system, that is, the duality of geocentrism and heliocentrism. After discussing the reasons for denying geocentrism with arguments from theoretical physics, we return to discussing the duality against the backdrop of the history of science, showing (...) that the issue was much more complex when the Ptolemaic paradigm passed to the Copernican one in the 16th century. The article shows that the paradigm shift presupposed the invention of a reality that took more than 100 years to stop being an invention and become a reality. From an epistemological point of view, a discovery, even if it corresponds to empirical facts, needs theoretical support to be considered true or, in the terms we are dealing with here, to be considered reality and part of common sense. Ontologically speaking, we cannot consider a certain worldview as an existing reality beyond the mental model that created it. (shrink)

Introduction. The book is a study in Adam Smith's system of ideas; its aim is to reconstruct the peculiar framework that Adam Smith’s work provided for the shaping of a semi-autonomous new discipline, political economy; the approach adopted lies somewhere in-between the history of ideas and the history of economic analysis. My two claims are: i) The Wealth of Nations has a twofold structure, including a `natural history' of opulence and an `imaginary machine' of wealth. The imaginary machine is a (...) kind of Newtonian theory, whose connecting links are principles; provided either by `partial' characteristics of human nature or by analoga of physical mechanisms transferred to the social world; ii) a domain of the economic, understood as a self-standing social sub-system, was discovered first by Adam Smith. His `discovery' of the new continent of the economic was an `unintended result' of a deviation in his voyage to the never-found archipelago of natural jurisprudence. -/- 1. Imaginary machines and invisible chains: natural philosophy and method. The first chapter reconstructs Smith's views on the method in natural philosophy, presented primarily in the History of Astronomy (HA). The peculiar kind of semi-sceptical Newtonianism which permeates the essay is highlighted. Its reconstruction of the history of one natural science is shown to be based on the assumptions of Hume’s epistemology, and to lead to a self-aware deadlock. Smith's dilemma is between an essentialist realism and sceptical instrumentalism; the Cartesian presuppositions he shares with Hume and with the 18th century as a whole make it impossible for him to overcome his dilemma. The following chapters will show how, on the one hand, Smith's skeptical methodology encourages him in the enterprise to `carve off' a new self-contained discipline and how, on the other hand, his epistemological dilemma is reflected in the inner tensions of his moral and political theory as well as in a number of basic oscillations concerning the status of the new discipline. -/- 2. Chessboards and clocks: moral philosophy and method. -/- The second chapter reconstructs Smith's views on the method in the parallel field of moral philosophy, including the theory of moral sentiments and natural jurisprudence. I argue that The Theory of Moral Sentiments, when considered together with with the Lectures on Jurisprudence, where Smith's peculiar version of a `weaker' form of natural law is presented, wins special interest, not only for the history of ethics but even more for the history of political theory and the social sciences. The two most striking features of Smith's work in this area are highlighted. First, his effort at reformulating the `practical science' is a methodologically self-aware attempt at applying the Newtonian method to moral subjects. Secondly, this attempt ends in a stalemate as two distinguished kinds of normative order are introduced: one ultimate order of Reason, ultimately justifiable but inaccessible, and one weaker order of our `natural sentiments', to which we have empirical access, but which is so variable as to lack any ultimate value as a basis for grounding our normative claims. These two parallel conundrums may arguably account for the author's inability to publish during his lifetime both The History of Astronomy and the projected history and theory of law and government. -/- 3. Wheels, dams, and gravitation: the structure of scientific argument in The Wealth of Nations. -/- The third chapter provides the core of the book, dealing with the structure of the argument in WN. I argue that the main presupposition that makes the shift possible from a `natural history' to a `system' approach is the Newtonian contrast of `mathematical' with `physical' explanation; that is, Smith drops any discussion of the "original qualities" of human nature that could account for economic behaviour, while introducing, as `principles' for the system, a set of `hypothetical' statements of `observed' regularities in human behaviour and of `observed' super-individual self-regulating mechanisms. In bringing this presupposition to light, the coexistence of a teleological with a mechanistic approach is clarified; fresh light is shed on the notion of the invisible hand by a comparison of its occurrence in Smith with the occurrence of the same expression (until now overlooked) in the correspondence between Newton and Cotes. Finally, the peculiar semi-prescriptive and semi-descriptive character of political economy are highlighted, and the consistency of Smith's `impure' semi-prescriptive social science, when understood in his own terms, is defended against familiar charges with inconsistency and against even more familiar strained modernizations. -/- 4. Apples, deer, and frivolous trinkets: the construction of the economic. -/- The fourth chapter draws consequences from the third, examining how Smith's achievement in political economy, marking its transition to scientific status, carried a re-description of the phenomena, creating the comparatively independent and unified field of the economic. Smith's achievement is interpreted not as the `discovery' of an autonomous character already possessed by the economy out there, so much as a Gestalt-switch by which our perception of social phenomena is modified making us `see' the partial order of the economy as an isolated system. To sum up, the autonomy of the economic in social reality and the autonomy of the economic in social consciousness are shown to be two sides of one process. -/- 5. Concluding considerations: Political economy and the Enlightenment halved. -/- A few suggestions on the status of economic theory two centuries after The Wealth of Nations in its relationship to ‘practical philosophy’ are illustrated.

This paper offers a general characterization of underdetermination and gives a prima facie case for the underdetermination of the topology of the universe. A survey of several philosophical approaches to the problem fails to resolve the issue: the case involves the possibility of massive reduplication, but Strawson on massive reduplication provides no help here; it is not obvious that any of the rival theories are to be preferred on grounds of simplicity; and the usual talk of empirically equivalent theories misses (...) the point entirely. (If the choice is underdetermined, then the theories are not empirically equivalent!) Yet the thought experiment is analogous to a live scientific possibility, and actual astronomy faces underdetermination of this kind. This paper concludes by suggesting how the matter can be resolved, either by localizing the underdetermination or by defeating it entirely.

The article undertakes a phenomenological interpretation of the description of contingency in two late-antique models of the relationship of time and eternity — in the theory of Plotinus, and in the eschatology of Paul on the basis of the First Epistle to the Thessalonians. Contingency as a possible property not of time, but of eternity, the presence of the supertemporal in the physical world — this hypothesis promotes a new view of the relationship between time and eternity and a new (...) view of the properties of time. Time remains as immeasurable as eternity, inheriting its character as a phenomenon of consciousness. The article also compares the ideas of H. Bergson and E. Husserl on duration and memory, on the coincidence of moments and the measurability of the movement of time. A turn to Ptolemaic cosmology proposed by Q. Meillassoux seems relevant, an appeal to ancient mathematics and ontology through the optics of post-metaphysical criticism. The search for a new correlationism is significant for the philosophy of time, and contingency, like any coincidence of thought and object, the world and the subject, the signifier and the signified, leads to new forms of manifestation, new phenomena of presence, a new fullness of being in history.

In recent years, Nietzsche’s views on (natural) science attracted a considerable amount of scholarly attention. Overall, his attitude towards science tends to be one of suspicion, or ambivalence at least. My article addresses the “Nietzsche and science” theme from a slightly different perspective, raising a somewhat different type of question, more pragmatic if you like, namely: how to be a Nietzschean philosopher of science today? What would the methodological contours of a Nietzschean approach to present-day research areas (such as neuroscience, (...) astrophysics, synthetic biology or climate studies) amount to? In other words, my paper reflects a shift of focus from author studies to extrapolation. The design of my article is as follows. I will start with the question (already widely discussed in the expert literature) to what extent Friedrich Nietzsche (a classical philologist by training) managed to familiarise himself with the natural sciences of his epoch. Subsequently, I will outline some basic methodological and conceptual ingredients of Nietzsche’s philosophy of science, focussing on core issues such as “genealogy”, “interpretation”, “enhancement” and “truth”. Next, I will elucidate Nietzsche’s genealogical methodology with the help of three case studies (three representative samples if you will) taken from Nietzsche’s writings and dealing with physiology, astronomy and neuro-psychology respectively. Finally, I will present the methodological contours of a Nietzschean understanding of contemporary technoscience. (shrink)

The main theory at the core of this monograph is that the person is an entity ontologically new, since she is able to perform an act of self-transcendence, which is meant as her critical distancing from her own “self”, understood as subject of social recognition (Anerkennung), in order to open to the encounter with the world (Weltoffenheit). This allows us to consider a person in a new way, different both from confessional interpretations that see her only as a center of (...) the spirit and from reductivistic views. Schelling examines the act of self-transcendence through the concept of ecstasy, whereas Scheler associates it with the phenomenological reduction. The act of self-transcendence, that Schelling sees as originated by the “hunger of being”, is at the roots of the formation process of a person (Bildung): the person takes her shape by exiting from her own self-referential dimension and encountering otherness. If considered from this viewpoint, Plato’s “epimeleia heautou” exceeds an intimistic perspective: the “care” is no more a solipsistic self-care, but rather becomes the care through which the person transcends her own self to open to the relationships with otherness. It turns, therefore, into a care for world-openness (care for Weltoffenheit). The transformation of the individual and of society so becomes the double-faced aspect of the same process. The development of this set of problems occurs through a dialogue with Schelling’s and Scheler’s positions, but it is also supported by a historical-philosophical investigation, that for instance provides evidence of the influences of Schelling’s Berlin period on Scheler’s last theories and on the philosophical anthropology of the 20th century. Schelling was the first to conceive the concept of “eccentricity” in an anthropological sense, since until then the term had been confined to Kepler’s astronomy. Consequently, the planets’ elliptic (eccentric) movement heightens to an emblematic metaphor of human nature and freedom. The monograph also examines a possible convergence between Plato’s epimeleia heautou and Scheler’s phenomenological reduction. The book ends with a chapter on the topic of Vorbild. The exemplary testimony, that is Vorbild, becomes witnessing evidence immune from any pedagogical-moralistic intent: in fact, if it should relapse into the rhetoric of the “wish to give a good example”, it would immediately conform to the opposite logic of the model. A model is universal in so far as it makes everyone more like the others, nullifying the diversity, whereas exemplariness is universal in so far as it makes everyone more unique and motivates each one to follow her own characteristic path of existential trans-formation. Exemplarity doesn’t convey any contents, but rather encourages a kind of solidaristic involvement. Yet there are also negative exemplarities (Gegenbild) that place obstacles in the formation and block the existence of the personal center. (shrink)

Gazali'nin hayatını 1095 yılında geçirdiğini söylediği krize göre üç döneme ayırmamız mümkündür. Kriz öncesi dönem, kriz dönemi (1095) ve kriz sonrası dönem. Bu dönemlerde akla ve felsefeye bakışı değişmiştir dolayısıyla felsefî ilimlerden sayılan matematik ilmine bakışı da değişmiştir. Gazali kriz öncesi ve kriz dönemlerinde aklı eleştirmekle birlikte çok sistematik bir eleştiri yaptığı söylenemez. Gazali bu dönemde felsefe yorumlarında 'felsefi/bilimsel aklı" din açısından zararlı görmemektedir hatta zaman zaman olumlu yanlarından bahsetmektedir. Makasıdu’l Felasife ve Tehafütü’l Felasife ‘de akılla ilgili mevzulara değinmiş, bazı (...) felsefî ilimlerin dinle alakalı olmadığını, din açısından fayda veya zarar vermediğini ifade etmiş ama temelde felsefi aklın “sadece dini (metafizik) konulara” yetmeyeceği kanaatine varmıştır. Fakat bu dönemde o, felsefeyi 'dinileştirme' çabasının bir sonucu olarak akıl eleştirisiyle karşımıza çıkmaktadır. Aklın, felsefenin ve felsefî ilimlerin (mantık, astronomi, fizik… vb.) kökenini Kur’an’a dayandırmış ve filozofların bütün bu ilimlerin ‘tümellerini’ dinden öğrendiklerini iddia etmiştir. Böylece Gazali, akılla bir teoloji kurmanın mümkün olmadığını ispatlayarak yani dini ‘akla uygun hale getirme’ girişimlerinin önüne geçerek ‘aklı ve bütün aklî ilimleri dine uygun hale’ getirmek için vahye ve mistik tecrübeye dayalı yeni bir sistem kurmuştur. Dinî akıl, vahyi anlar ve uygular. Kriz sonrası dönemde bütün felsefî sistemleri dinî ve mistik/gnostik bir düşünce etrafında yorumlayan Gazali'de akıl tamamen dinileşmektedir. Avam ilimleri seviyesine indirdiği felsefî (tıp, astronomi, kimya, biyoloji, mantık, matematik vs.) ve dinî ilimleri (kelam, fıkıh ve tefsir) mistik bir zihniyetle yeniden ele alır. Felsefî ilimlerin esası dinîdir ve insanlar bu ilimleri peygamberlerden öğrenmiştir. Kelam ilmi, aklî bir ilim değil, dini bir ilimdir, kelamı kullanarak akli hükümler vermekten vazgeçip sadece dini ve uhrevi hükümler vermesi sağlanmalıdır. Fıkıh ilmi de aklî bir ilim değil dini bir ilimdir ve fıkıh alimleri sadece ahiretle ilgili hüküm verilmelidir. Bunlardan daha üstün olan ise havas ilimleridir. Havas ilmi Gazali'ye göre gnostik tasavvuf öğretisidir. Dünyevî akıl insanı yanılttığı ve ona güvenilmez olduğu için akıl yerine peygamberin vahyi gelmelidir ve ondan sonra vahye benzerliği dolayısıyla "velinin ilhamı" yer almalıdır. Bu ise ilk başta dini anlaması için gerekli olan ‘dinî akıl” ve daha sonra ruh, aşk ve nur yoluyla elde edilmektedir. (shrink)

Fizik disiplininde astronomiye yönelik sorular Johannes Kepler (1571-1630) ve Isaac Newton (1643-1727) gibi fizik alanında devrim yaratan düşüncelerin ortaya çıkmasına yol açmıştır. Kepler ‘Yeni Astronomi’ (Astronomia Nova), ‘Dünya'nın Uyumu’ (Harmonice Mundi) ve ‘Kopernik Astronomisinin Özeti’ (Epitome Astronomiae Copernicanae) adlı çalışmalarından hareketle ileri sürdüğü gezegensel hareket yasaları, Newton ise 1687 yılında yayımlanan ‘Doğa Felsefesinin Matematiksel İlkeleri’ (Philosophiae Naturalis Principia Mathematica) isimli çalışmasında yer verdiği hareket yasaları ile fizik disiplininde Aristoteles fiziğinin terk edilerek yeni bir fizik anlayışının ortaya çıkmasına ve böylece fizik (...) alanında bir devrimin meydana gelmesine sebep olmuşlardır. Fizik disiplininde gerçekleşen bu devrimin bir benzeri ise canlıların çalışılması ya da biyoloji disiplini söz konusu olduğunda 1800’lerden biraz daha geç bir zamana rastlamaktadır. Biyolojide gerçekleşen devrimsel düşünce doğal seçilim mekanizması ile canlılarda zaman içerisinde gerçekleşen değişim ve dönüşüm sürecini açıklayan Charles Darwin’in evrim kuramına yönelik görüşlerini ortaya koymasına tekabül etmektedir. Bu kapsamda çalışmada öncelikli olarak canlılarda meydana gelen değişim süreçlerine yönelik tespitleri ile Darwin’in görüşlerinin olgunlaşmasına katkıda bulunan Fransız Transformistler (Dönüşümcüler) olarak da bilinen Georges-Louis Leclerc (Comte de Buffon), Jean-Baptiste Lamarck ve George Cuvier’in görüşlerine yer verilmektedir. Ardından bu bilim insanlarının canlılardaki dönüşümsel ya da evrimsel değişime ilişkin argümanlarının Darwin’in evrim kuramını nasıl etkilediği ve bu etkilerin sonucunda biyoloji biliminde nasıl bir devrimin ortaya çıkmasına yardımcı oldukları aktarılmakta ve bu çerçevede Darwin’in on dokuzuncu yüzyılda biyoloji biliminde devrime yol açan tespitlerine ve evrim kuramının ayrıntılarına yer verilmektedir.

In an Enquiry Concerning Human Understanding, Hume distinguishes between two approaches to what we might call psychology: first, one that appeals to common sense to make virtue seem attractive and second one that attempts to describe the principles governing the mind. Within the second approach, he distinguishes two parts: first, a descriptive branch he calls ‘mental geography’ and, second, a branch he compares to Newton’s project in astronomy. I explain the Hume’s vision of Newtonian psychology, and then I explain (...) its application to Hume’s psychological theory in the first Enquiry. Hume’s attempt to explain causal inference in Part 2 of Section 5 is shown to be an attempt at Newtonian psychology: it’s speculative, explanatory, and attempts to enunciate a psychological law. The paper closes by asking whether Hume succeeded in his attempt to put psychology on Newtonian foundations. (shrink)

The Ptolemaic universe is complementary of the Copernican universe.

The year in the title comes from “2001: A Space Odyssey”. The article was inspired by reading about the Vera C. Rubin Telescope, due to begin operations in Chile next year. The article I read talked about the telescope photographing the entire Southern Hemisphere sky but the heading spoke of watching the whole universe. Reconciling the Southern Hemisphere with the entire cosmos quickly became the challenge I chose to accept. The Unimaginable Telescope uses multi-messenger (combined neutrino / gravitational / electromagnetic) (...) astronomy, quantum (and macroscopic) entanglement, as well as Unipositional Quantum Mechanics to not only observe the entire universe but also to instantly transmit messages to every possible coordinate in time as well as space and, from “reflections” of those signals which arrive back on Earth of 4 001 instantaneously, pinpoint the locations of extraterrestrial civilizations. The telescope’s functions include the potential to form a spaceship and crew that could be transported to the Voyager and Pioneer probes that exited the solar system way back in the early 2000s. They’d visit the spaceprobes in order to service and repair them, collect them and bring them back to a museum, or whatever … Other topics covered by this article include dark matter and modified dark matter, human/AI partnership, electric dipole moment, quantum/macroscopic entanglement, hidden electromagnetism in cosmological constant, time dilation, Wick rotation, Vector-Tensor-Scalar (and elliptical VTS) geometry, quantum spin, precession related to Mercury and Planet 9, Riemann hypothesis, solar system and intergalactic and time travel, infinite and eternal universe with a beginning, ETs the Extraterrestrials, model universe, origin of life, heaven on earth, Weyl and Majorana fermions, topological insulators and topological superconductors, topological propulsion and topological manufacturing, consciousness, Higgs boson and Higgs field, plus ocean tides and Saturn’s moon Enceladus with A Brief History of Gravity.

Johannes Müller von Königsberg (1436-1476), better known as Regiomontanus, is widely considered as the most influential astronomer and mathematician of 15th-century Europe. He was active as an astrologer and deemed astrology to be the queen of mathematical sciences. Despite this, Regiomontanus's astrological activity has yet to be fully explored. A brief examination of Regiomontanus's manuscripts shows that his astrological interests were accompanied by interests in the arts and in methods of prognostication. This article studies an unconventional astrological-chiromantical text, whose relevance (...) is threefold: a) it sheds new light on Regiomontanus's astrological interests; b) it enriches our knowledge of Regiomontanus's efforts to learn and understand Greek-Regiomontanus transcribed it into his own manuscript during his sojourn in Italy from 1460-1467; and c) it is the sole extant text in the Greek tradition that provides a system for prognostication from the study of a person's hand, the parts of which are considered as being under the domain of planets. The article provides an English translation of Regiomontanus's transcription, alongside a brief commentary, and studies the intellectual and historical context of that production through manuscript analysis.

This essay examines the quantitative aspects of Greco-Roman science, represented by a group of established disci¬plines, which since the fourth century BC were called mathēmata or mathē¬ma¬tikai epistē¬mai. In the group of mathēmata that in Antiquity normally comprised mathematics, mathematical astronomy, harmonics, mechanics and optics, we have also included geography. Using a dataset based on The Encyclopaedia of Ancient Natural Scientists, our essay considers a community of mathēmatikoi (as they called themselves), or ancient scientists (as they are defined for (...) the purposes of the present paper) from a sociological point of view, focusing on the size of the scientific population known to us and its disciplinary, temporal and geographical distribution. A diachronic comparison of neighboring and partly overlapping communities, ancient scientists and philosophers, allows the pattern of their interrelationship to be traced. An examination of centers of science throughout ancient history reveals that there were five major centers – Athens, Alexandria, Rhodes, Rome and Byzantium/Constantinople – that appear and replace one another in succession as leaders. These conclusions serve to reopen the issue of the place of mathēmata and mathēmatikoi in ancient society. (shrink)

Berkeley, Newton, Explanation, and Causation -/- I argue in this paper that Berkeley’s conception of natural law explanations, which echoes Newton’s, fails to solve a fundamental problem, which I label “explanatory asymmetry"; that the model of explanation Berkeley uses fails to distinguish between explanations and justifications, particularly since Berkeley denies real (efficient causes) in non-minded nature. At the end I suggest Berkeley might endorse a notion of understanding, say in astronomy or mechanics, which could be distinguished from explanation.
