Abraham ibn Ezra's scientific corpus represented an exceptional case: instead of the common Latin model embodied by the scholar coming from the Christian North to the Iberian Peninsula to initiate a translation enterprise, we have in Ibn Ezra the contrary case of an intellectual imbued with the Arabic culture, who abandons al-Andalus, roams around the Christian countries and delivers in his wandering through Italy, France and England, the scientific and cultural cargo that he amassed during his youth in al-Andalus. The (...) main purpose of this article is to provide a picture of Ibn Ezra's scientific corpus as comprehensive and detailed as possible given the present state of research. The paper will fall into two main parts: Ibn Ezra's scientific work will be broken up into three main genres: Mathematics, Astronomy, Scientific Instruments and Tools; The astrological encyclopaedia; Translations from Arabic into Hebrew. In the second part, Ibn Ezra's scientific corpus will be reassembled as a whole in order to provide a global characterization, trying to point out its general organization and shape, and to indicate its main aims and special traits revealing Ibn Ezra personal contribution.

Le Tractatus particulares est un ouvrage en quatre parties attribué à Abraham Ibn Ezra (ca. 1089-ca. 1161), qui nous est parvenu en deux traductions latines. Le présent article montre que, malgré les attestations dans les incipits et les explicits des deux traductions latines, le Tractatus particulares ne peut pas être un ouvrage authentique d’Ibn Ezra, ni un recueil d’écrits de sa plume. L’essentiel du Tractatus particulares est constitué de traductions de l’arabe en hébreu, réalisées bien après la mort d’Ibn Ezra (...) et associées à son nom par la suite. L’article entend aussi montrer que la source hébraïque du Tractatus particulares était sans doute conçue comme un ouvrage astrologique complet, une sorte d’encyclopédie astrologique médiévale.

The article describes the fourteen passages of the encyclopaedia containing the word dawla. The Ikhwān introduce a cyclical conception of the alternation of ruling dynasties. After the dynasty of the evil reached its apex, the dynasty of the good begins when learned agree “on a unique school and a sole religion”. The Ikhwān introduce this as a wondrous event, close to become reality. This conception is linked to their vision in expectance of the legitimate rulers after the debasement of the (...) Family of the Prophet following Muḥammad’s death. The connection of these passages with the rituals described in Ep. 50 On the Various Kinds of Management (where political vision, astrology and magic are combined) might confirm the Ikhwān’s Ismā ‘īlī commitment.

The Ikhwan al-Safa (Brethren of Purity), the anonymous adepts of a tenth-century esoteric fraternity based in Basra and Baghdad, hold an eminent position in the history of science and philosophy in Islam due to the wide reception and assimilation of their monumental encyclopaedia, the Rasa'il Ikhwan al-Safa (Epistles of the Brethren of Purity). This compendium contains fifty-two epistles offering synoptic accounts of the classical sciences and philosophies of the age; divided into four classificatory parts, it treats themes in mathematics, logic, (...) natural philosophy, psychology, metaphysics, and theology, in addition to didactic fables. Epistles 32 to 36 comprise the first five treatises in the third division of the Rasa'il, on the sciences of the soul and intellect. Combining Islamic revelation with Hellenistic philosophy, the Ikhwan delineate herein their metaphysical system. Epistles 32 and 33 present adaptations of the Pythagorean doctrines, and of Neo-Platonist leitmotifs, whereby a numerical analogy is applied to the unique and transcendent God, or the One, from whom all existence emanates. Epistle 34 takes up the pervasive theme of the correspondence between microcosm and macrocosm, situating the human being as the central link between the celestial and terrestrial realms. In Epistle 35, we find an explanation of the intellectual faculties of the individual human soul, whose ultimate aim is ascension to the timeless reality of pure intellect. Finally, Epistle 36 presents itself as the astrological epistle par excellence of the Rasa'il; from the coming-to-be of worms, to the emergence of religions and empires, nothing in the sub-lunar sphere escapes the determining influence of the celestial cycles.

The Ikhwan al-Safa (Brethren of Purity), the anonymous adepts of a tenth-century esoteric fraternity based in Basra and Baghdad, hold an eminent position in the history of science and philosophy in Islam due to the wide reception and assimilation of their monumental encyclopaedia, the Rasa'il Ikhwan al-Safa (Epistles of the Brethren of Purity). This compendium contains fifty-two epistles offering synoptic accounts of the classical sciences and philosophies of the age; divided into four classificatory parts, it treats themes in mathematics, logic, (...) natural philosophy, psychology, metaphysics, and theology, in addition to didactic fables. The Rasa'il constitutes a paradigmatic legacy in the canonization of philosophy and the sciences in mediaeval Islamic civilization, as well as having shown a permeating influence in Western culture. This is the fifth volume in a series presenting the very first critical edition of the Rasa'il in its original Arabic, complete with the first fully annotated English translation. Epistle 52: On Magic is the last in the corpus, and presents the short version of the 'Epistle on Magic, Incantations, and the Evil Eye'. Within its pages the authors of the epistle argue for the legitimacy of magic and the other occult sciences, and seek confirmation of their views in authorities as diverse as Plato, the Qur'ân, the Torah, the astrologer Abû Ma'shâr, and the mysterious sect of pagan star-worshippers known as the Sabians of Harrân. As in all other volumes of the series, this volume provides the first critical edition of the Arabic text, together with an English translation and a substantial range of notes. An extensive introduction highlights the unique relevance of this treatise within the framework of the Brethren's encyclopaedia itself, and to the history of science in general. (shrink)

The term pseudoscience refers to a highly heterogeneous set of practices, beliefs, and claims sharing the property of appearing to be scientific when in fact they contradict either scientific findings or the methods by which science proceeds. Classic examples of pseudoscience include astrology, parapsychology, and ufology; more recent entries are the denial of a causal link between the HIV virus and AIDS or the claim that vaccines cause autism. To distinguish between science and pseudoscience is part of what the philosopher (...) Karl Popper referred to as the demarcation problem, a project that has been dismissed by another philosopher, Larry Laudan, but that keeps gathering much interest in philosophers, scientists, educators, and policymakers. This entry provides the basics of the debate about demarcation, as well as a brief discussion of why it is of vital importance not just intellectually but for society at large. (shrink)

The City of the Sun is a literary, political, and philosophical work by Tommaso Campanella, one of the most significant intellectual figures of the late Renaissance. While Campanella was a prolific author—writing on natural philosophy, ethics, prophecy, magic, astrology, theology, metaphysics, and politics—City of the Sun remains his most famous text. The work, in the form of a dialogue between a Grand Hospitaller and a Genoese helmsman, describes an imaginary city located in the Tabrobane (today’s Sri Lanka). The Genoese seaman (...) describes in detail the structure of the city as well as the inhabitants’ way of life, military training, religious and philosophical beliefs, and political governance.

The origin of my article lies in the appearance of Copeland and Proudfoot's feature article in Scientific American, April 1999. This preposterous paper, as described on another page, suggested that Turing was the prophet of 'hypercomputation'.

In the summer of 1999, I circulated an open letter criticising the Scientific American article. I included criticism of this Encyclopedia entry. This was forwarded to Prof. (...)

Abstract: Many astrologers attribute a successful birth-chart reading to what they call intuition or psychic ability,where the birth chart acts like a crystal ball. As in shamanism,they relate consciousness to a transcendent reality that,if true, might require are-assessment of present biological theories of consciousness.In Western countries roughly 1 person in 10,000 is practising or seriously studying astrology, so their total number is substantial. Many tests of astrologers have been made since the 1950s but only recently has a coherent review been (...) possible. A large-scale test of persons born less than five minutes apart found no hint of the similarities predicted by astrology. Meta-analysis of more than forty controlled studies suggests that astrologers are unable to perform significantly better than chance even on the more basic tasks such as predicting extraversion. More specifically,astrologers who claim to use psychic ability perform no better than those who do not. The possibility that astrology might be relevant to consciousness and psi is not denied, but such influences, if they exist in astrology,would seem to be very weak or very rare. -/- . (shrink)

Using astrology as a case study, this paper attempts to establish a criterion for demarcating science from pseudoscience. Numerous reasons for considering astrology to be a pseudoscience are evaluated and rejected; verifiability and falsifiability are briefly discussed. A theory is said to be pseudoscientific if and only if (1) it has been less progressive than alternative theories over a long period of time, and faces many unsolved problems, but (2) the community of practitioners makes little attempt to develop the theory (...) towards solutions of the problems, shows no concern for attempts to evaluate the theory in relation to others, and is selective in considering confirmations and disconfirmations. This criterion has the interesting consequence that a theory can be scientific at one time but pseudoscientific at another. (shrink)

The philosophy of science is the branch of philosophy that examines the profound philosophical questions that arise from scientific research and theories. A sub-discipline of philosophy that emerged in the twentieth century, the philosophy of science is largely a product of the British and Austrian schools of thought and traditions. The first in-depth reference in the field that combines scientific knowledge with philosophical inquiry, The Philosophy of Science: An Encyclopedia is a two-volume set that brings together an international team (...) of leading scholars to provide over 130 entries on the essential concepts in the philosophy of science. The areas covered include biology, chemistry, epistemology and metaphysics, physics, psychology and mind, the social sciences, and key figures in the combined studies of science and philosophy. Essays range in length from 3,000 to 7,500 words and represent the most up-to-date philosophical thinking on timeless scientific topics such as determinism, explanation, laws of nature, perception, individuality, time, and economics as well as timely topics like adaptation, conservation biology, quantum logic, consciousness, evolutionary psychology, and game theory. Offering thorough explorations and destined to become the most authoritative presentation of the field available, this Encyclopedia is a unique and groundbreaking guide to this fascinating field.

In the spring of 1937, the University of Chicago Press mailed hundreds of subscription forms for its latest enterprise – a projected series of twenty short monographs by various philosophers and scientists. Together the monographs were to form the first section of the International Encyclopedia of Unified Science. Included in each mailing was an introductory prospectus which began:Recent years have witnessed a striking growth of interest in the scientific enterprise as a whole and especially in the unity of science. (...) The concern throughout the world for the logic of science, the history of science, and the sociology of science reveals a comprehensive international movement interested in considering science as a whole in terms of the scientific temper itself. A science of science is appearing. The extreme specialization within science demands as its corrective an interest in the scientific edifice in its entirety. This is especially necessary if science is to satisfy its inherent urge for the systematization of its results and methods and if science is to perform adequately its educational role in the modern world. Science is gradually rousing itself for the performance of its total task. (shrink)

Some philosophers assert that astrology is a false theory. The simplest way to argue against all astrology is to identify a proposition that any kind of astrology must be committed to and then show that this proposition is false. In this paper I draw attention to some misconceptions about which propositions are essential to astrology.

Critical edition of the earliest known astrological autobiography. The present book reveals the riches of the earliest known astrological autobiography, authored by Henry Bate of Mechelen (1246-after 1310). Exploiting all resources of contemporary astrological science, Bate conducts in his Nativitas a profound self-analysis, revealing the peculiarities of his character and personality at a crucial moment of his life (1280). The result is an extraordinarily detailed and penetrating attempt to decode the fate of one's own life and its (...) idiosyncrasies. The Astrological Autobiography of a Medieval Philosopher offers the first critical edition of Bate's Nativitas. An extensive introduction presents Bate's life and work and sheds new light on the reception and use of Greek, Latin, Arabic, and Hebrew texts among scholars in Paris at the end of the 13th century. The book thus provides a major new resource for scholars working on medieval science, autobiography, and notions of personhood and individuality. (shrink)

During most of Copernicus's life he was an inhabitant of political settings rather than scientific settings. His settings from 1492 to 1500 offered him a large amount of information about astrology. Most of Copernicus's known significant contacts at the Jagiellonian University had expertise in astrology, in some cases at national level. Information was available to Copernicus about the inaccuracies and the difficulties of astrological practice as well as about a notably successful astrologer-patron relationship. The experience of astrological practice (...) that was available to Copernicus in Bologna ranged from the benign to the potentially dangerous, and his departure from Bologna was contemporary with the threat of military reprisals against the town which appeared to show the incorrect outcome of the relevant prediction in Domenico Maria di Novara's prognostication for 1500. After this date Copernicus no longer participated in roles in which prognostication was a duty, he generally inhabited locations that were less potentially dangerous than Bologna was in 1500, and while at some later points he was keen to interest astrologers in his astronomical work, astrology is completely absent from his own explanations of the reasons for his astronomical work.

Feelings and experiences vary widely. For example, I run my fingers over sandpaper, smell a skunk, feel a sharp pain in my finger, seem to see bright purple, become extremely angry. In each of these cases, I am the subject of a mental state with a very distinctive subjective character. There is something it is like for me to undergo each state, some phenomenology that it has. Philosophers often use the term ‘qualia’ (singular ‘quale’) to refer to the introspectively accessible, (...) phenomenal aspects of our mental lives. In this standard, broad sense of the term, it is difficult to deny that there are qualia. Disagreement typically centers on which mental states have qualia, whether qualia are intrinsic qualities of their bearers, and how qualia relate to the physical world both inside and outside the head. The status of qualia is hotly debated in philosophy largely because it is central to a proper understanding of the nature of consciousness. Qualia are at the very heart of the mindbody problem.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 27.1 (2003) 80-97 [Access article in PDF] Literary Truth as Dreamlike Expression in Foucault's and Borges's "Chinese Encyclopedia" Robert Wicks ALTHOUGH THE TOPIC REMAINS MOSTLY unexplored, Michel Foucault had an aesthetic and intellectual attraction towards writers and artists in the Spanish-speaking tradition. For example, at the conclusion of his Histoire de la folie (Madness and Civilization, 1961)—a book which brought him extensive intellectual recognition in (...) France—Foucault drew his readers' attention to José de Goya y Lucientes's (1746-1828) well-known etching, El Sueño de la Razón Produce Monstruos (The Sleep of Reason Brings Forth Monsters, Plate 43 of Los Caprichos, 1797). In Foucault's estimation, by revealing a "night which is doubtless that of classical unreason," Goya's work represented a socially removed condition within which people encounter "what is most solitary" and experience what is "deepest" within themselves. With his reference to Goya's imagery, Foucault illustrated a major theme of his history of madness, namely, how people referred to as "mentally ill" experienced a gradual, physical exclusion from participation in public society, and how they were eventually isolated in a more frightening way: within their physical confinement, they were subject to techniques of psychological and spiritual alienation that reduced them to a condition of utter solitude.In a comparable, if not more central manner, Foucault used as thematic motifs for the preface, first and second chapters of a book for which he is widely known, Les Mots et les choses (The Order of Things, 1966), the work of three major writers and artists from the Spanish-speaking world: Jorges Luis Borges (1899-1986), Diego Velázquez (1599-1660), and Miguel de Cervantes (1547-1616). Among these references, the most popular is probably Foucault's discussion of [End Page 80] Velázquez's Las Meninas—a painting which captured Foucault's interest as a perfect exemplar of its time period—and which inspired him to devote the entire first chapter of his book to decoding the mechanics of its perspectival arrangement. And within the community of those who read, write and discuss the interrelationship between Foucault's thought, literary theory and the contemporary emphasis upon the multivocal quality of textual meaning, Foucault's citation of an excerpt from a short story by Borges—the subject of this essay—is also familiar. Foucault introduced his 1966 book, The Order of Things, with the following words: This book first arose out of a passage in Borges, out of the laughter that shattered, as I read the passage, all the familiar landmarks of my thought—our thought, the thought that bears the stamp of our age and our geography—breaking up all the ordered surfaces and all the planes with which we are accustomed to tame the wild profusion of existing things, and continuing long afterwards to disturb and threaten with collapse our age-old distinction between the Same and the Other. This passage quotes a "certain Chinese encyclopedia" in which it is written that "animals are divided into: (a) belonging to the Emperor, (b) embalmed, (c) tame, (d) suckling pigs, (e) sirens, (f) fabulous, (g) stray dogs, (h) included in the present classification, (i) frenzied, (j) innumerable, (k) drawn with a very fine camelhair brush, (l) et cetera, (m) having just broken the water pitcher, (n) that from a long way off look like flies." In the wonderment of this taxonomy, the thing we apprehend in one great leap, the thing that, by means of the fable, is demonstrated as the exotic charm of another system of thought, is the limitation of our own, the stark impossibility of thinking that. 1The short story from which Foucault extracted the above, quasi-cubistic, excerpt was published in Borges's 1952 collection, Otras Inquisiciones (Other Inquisitions), and is entitled, "The Analytical Language of John Wilkins." Although this story's entirety is rarely surveyed in discussions of Foucault, appreciating its broader contents helps illuminate why Foucault began The Order of Things with this entertaining and bizarre segment. Borges's original... (shrink)

Astrology, its legitimacy, and the limits of its acceptable practice were debated in sixteenth- and seventeenth-century Europe. Many of the related arguments were mediated by the work of Giovanni Pico della Mirandola and the responses to it. Acknowledging the complexities of the relationship between astrological ideas and Christian teachings, this paper focuses on the Catholic debates by specifically considering the decisions about astrology taken by the Spanish Inquisition. The trials of astrologers are examined with the aim of understanding the (...) role of experts in astrology in early modern Spain. This study brings into view the specific nature of the debate on astrology in Spain, the consequences of the actions of the Inquisition and the social control it exerted. The historical events discussed comprise a particular case and also mirror the general debates about astrology taking place in early modern Europe. The experts’ opinions expressed in trials and in reports about the discipline received by the Inquisition reveal two key traits of the debate: the dispute about who had the authority to decide on the legitimacy of astrology and the disagreement about what constituted natural and judicial astrological practices. These led to different opinions about what was to be done with each defendant and about what content in their books ought to be forbidden. (shrink)

Speight has recently raised the question, which he himself leaves unanswered, how naturalism relates to spirit in Hegel’s philosophy of art. ‘Naturalism’ denotes an explanation that invokes aspects of nature that are (allegedly) irreducible or resistant to thought. I call nature ‘stubborn’ insofar as it evinces resistance to its being formed by thought and hence to its being united with it. This paper argues that §§556, 558 and 560 of Hegel’s Encyclopedia answer Speight’s question by specifying three elements of (...) nature that, first, are present in art and, second, are resistant to thought. These are materiality, natural form, and genius. They exhibit nature’s stubbornness in art. This stubbornness, I argue, is what justifies Hegel’s claim that art is absolute spirt only implicitly (§556), which leads to the claim that art needs to be superseded by religion and philosophy. In this way, Speight’s question receives a precise answer. (shrink)

Translations, especially of important texts, tend to be controversial. In a collaborative translation, the controversy will start during the process itself, and may persist until the end. In our case this is reflected in two translators’ introductions. Translators and reviewers agree or disagree on the basis of certain principles. There are, one could say, two “schools”: those in favor of more contextual choices of terminology, and those striving for strict consistency. The first will be more inclined to distinguish between “technical” (...) and “non-technical” uses of the same term, and consider this to be part of the translator’s role. The latter will try to avoid making these distinctions, and leave as much room as possible for the reader to decide. The first also tend to see the translation as standing on its own, readily intelligible to those who are without any knowledge of the original language. The latter intend to serve primarily readers who are interested in developing some, progressively better, knowledge of the text in its original language. They will attach more importance to an extensive glossary, which ideally should be applicable to the translated author’s entire corpus. (shrink)

Pliny's Natural History is often referred to as one of the first western encyclopedias and its encyclopedism is central to how it is used and understood. This article argues for a reassessment of the grounds on which we call the Natural History an encyclopedia by reexamining its relationship to the works of Cato, Varro, and Celsus and to the ancient educational concept of enkuklios paideia. If Pliny's Natural History is an encyclopedia, it is not because it belonged to (...) an ancient genre of encyclopedias that ancient readers and writers recognized as such; its encyclopedism needs to be understood instead as a product of the text's reception history.

The paper demonstrates that a detailed analysis of Hegel’s criticism of rationalist metaphysics in the “Vorbegriff” (Preliminary Conception) chapter of the Encyclopedia Logic can shed light on the following critical features of Hegel’s metaphysics: (1) advancing semantic holism as an alternative to semantic atomism; (2) renouncing the projection of a substance-attribute formal structure onto actuality; (3) dismissing sense perception as the source of conceptual content; and (4) rejecting dualist ontology.

In the Early Modern era of encyclopedias, the Bible functioned as a tool for managing and organizing the superabundance of information. From Johann Alsted to Johann Scheuchzer, this paper traces the use of the Biblical encyclopedia and the ways that the Bible was deployed to control the data that flooded the world of Early Modern scholarship. In a variety of contexts, the Bible served as a structure for generating meaningful statements from informational noise. In turn, the use of the (...)

Astrology is seen as a dubious discipline in many contemporary discussions. However, all critiques of astrology treat it as a contending scientific discipline in the same way that mainstream sciences such as physics, statistics, or biology is a scientific discipline. The current paper shows that there is an alternative description possible, based on ideas of action theory, which both protects the integrity of the practice of astrology, and renders it a reasonable discipline, without making superfluous claims about its predictive efficacy. (...) The argument hinges on discovering form concepts which best capture situation-types which are encountered in daily life. The three central aspects of astrology, viz., (a) planetary influence at a distance on our lives, (b) the determination of such influence based on the calendaring of birth, and (c) the salutary effects of rituals to propitiate the planets or suitably alter their influence are all redescribed to show that as effective material causes they distort the nature of the astrological activity but as form-concepts have a central role in generating practical knowledge.

Sexuality has captured the imagination of thinkers since antiquity. It has inspired numerous creative works and posed myriad ethical, legal, and social challenges. Unlike other references which discuss the biology of sex, this encyclopedia explores sexuality as the subject of philosophy.

persuasive argument for the claim that we ought to evaluate mathematics from a mathematical point of view and reject extra-mathematical standards. Maddy considers the objection that her arguments leave it open for an ‘astrological naturalist’ to make an analogous claim: that we ought to reject extra-astrological standards in the evaluation of astrology. In this paper, I attempt to show that Maddy's response to this objection is insufficient, for it ultimately either (1) undermines mathematical naturalism itself, leaving us with (...) only scientific naturalism, or (2) leaves open the possibility of other unpalatable naturalisms.

In this second article, I look at the history of the creation of the “Encyclopedia of Artistic Terminology” within the State Academy of the Artistic Sciences. I analyze various versions of the encyclopedia’s conception proposed by Wassily Kandinsky and Gustav Shpet and also at the theoretical bases for these conceptions. I then show how the work on the Encyclopedia was connected with the institutional transformations in the Academy. A key factor in the work on the Encyclopedia (...) was the extensive discussions of the fundamental aesthetic terms that took place in the Philosophy Department and in sections of GAKhN. As the dynamics of the discussions also determined changes in the conception of the Encyclopedia, so work on it shifted more and more from a project for creating a new system of aesthetic concepts to a reconstruction of the “history of concepts.” Such a transition marked the main vector of the development of European discussions about aesthetic concepts—from the creation of systems of aesthetic categories to historical reflection on the semantic transformations of categories. In conclusion, I investigate the cessation of work on the Encyclopedia in 1929 in response to the outside ideological pressure and the elimination of the possibility for autonomous theoretical work within the walls of the Academy.
