This paper explores the similarities between the conceptual structure of quantum theory and relational biology as developed within the Rashevsky-Rosen-Louie school of theoretical biology. With this aim, generalized quantum theory and the abstract formalism of (M,R)-systems are briefly presented. In particular, the notion of organizational invariance and relational identity are formalized mathematically and a particular example is given. Several quantum-like attributes of Rosen’s complex systems such as complementarity and nonseparability are discussed. Taken together, this work emphasizes the possible role of (...) self-referentiality and impredicativity in quantum theory. (shrink)

In this paper, we analyze the astronomical tables in al-Zīj al-Muqtabis by Ibn al-Kammād (early twelfth century, Córdoba), based on the Latin and Hebrew versions of the lost Arabic original, each of which is extant in a unique manuscript. We present excerpts of many tables and pay careful attention to their structure and underlying parameters. The main focus, however, is on the impact al-Muqtabis had on the astronomy that developed in the Iberian Peninsula and the Maghrib and, more generally, on (...) the transmission and diffusion of Indian astronomy in the West after the arrival of al-Khwārizmī’s astronomical tables in al-Andalus (Muslim Spain) in the tenth century. This tradition of Indian origin competed with the Greek tradition represented by al-Battānī’s astronomical tables and was much more alive in the Iberian Peninsula and the Maghrib than previously thought. From Spain, the Indian tradition entered mainstream European astronomy, where we find echoes of it in all versions of the Alfonsine Tables, both in manuscript and in the printed editions (beginning in 1483), as well as in Copernicus’s De Revolutionibus, published in 1543.

A table in five columns for the radii of the Sun, the Moon, and the shadow is included in sets of astronomical tables from the fifteenth to the early seventeenth century, specifically in those by John of Gmunden (d. 1442), Peurbach (d. 1461), the second edition of the Alfonsine Tables (1492), Copernicus (d. 1543), Brahe (d. 1601), and Longomontanus (d. 1647). The arrangement is the same and the entries did not change much, despite many innovations in astronomical theories in this (...) time period. In other words, there is continuity in presentation and, from the point of view of the user of these tables, changes in the theory played no role. In general, the methods for computing the entries are not described and have to be reconstructed. In this paper, we focus on the users of these tables rather than on their compilers, but we refer to modern reconstructions where appropriate. A key issue is the treatment of the size of the Moon during a solar eclipse which was not properly understood by Tycho Brahe. Kepler’s solution and that of his predecessor, Levi ben Gerson (d. 1344), are discussed. (shrink)

The anonymous set of astronomical tables preserved in Paris, Bibliothèque nationale de France, MS lat. 10262, is the first set of displaced tables to be found in a medieval Latin text. These tables are a reworking of the standard Alfonsine tables and yield the same results. However, the mean motions are defined differently, the presentation of the tables is unprecedented, and some new functions are introduced for computing true planetary longitudes. The absence of any instructions as well as unusual technical (...) terms in the headings make it difficult to appreciate the cleverness that went into the construction of these tables that are extant in a unique copy. In this article we provide a detailed analysis of these tables and their underlying parameters. The displaced tables are typical of a pervasive tendency in Islamic science to provide extensive and elegant numerical tables for the convenience of practitioners. The underlying astronomical theory is neither questioned nor affected.Edward S. Kennedy. (shrink)

In this article, we report the discovery of a new type of astronomical almanac by Joseph Ibn Waqār (Córdoba, fourteenth century) that begins at second station for each of the planets and may have been intended to serve as a template for planetary positions beginning at any dated second station. For background, we discuss the Ptolemaic tradition of treating stations and retrograde motions as well as two tables in Arabic zijes for the anomalistic cycles of the planets in which the (...) planets stay at first and second stations for a period of time (in contrast to the Ptolemaic tradition). Finally, we consider some medieval astrological texts where stations or retrograde motions are invoked. (shrink)

Astronomers have always considered the motion of the Moon as highly complicated, and this motion is decisive in determining the circumstances of such critical celestial phenomena as eclipses. Table-makers devoted much ingenuity in trying to find ways to present it in tabular form. In the late Middle Ages, double argument tables provided a smart and compact solution to address this problem satisfactorily, and many tables of this kind were compiled by both Christian and Jewish astronomers. This paper presents multiple examples (...) of the diversity of approaches adopted by compilers of tables who used this powerful tool, and brings to light intellectual interactions among them that are otherwise hidden from view.

La relación entre seres humanos y otros anymales (anymals) (Kemmerer, 2006) es, por definición, asimétrica. A lo largo de la historia se han esgrimido múltiples argumentos para justificar un supuesto excepcionalismo humano (excepcionalism), desde la atribución de derechos divinos a una mayor inteligencia, legitimando así un sistema de explotación denominado dominación (domination) (Manfredo et al. 2019). Las relaciones entre especies y cómo se conciben son un tema difícil. Hay muchos modos de enfocar las relaciones entre el humano y los anymales, (...) desde la adoración religiosa (vacas en la India) a la explotación (investigación biomédica). Además en Occidente surgen formas alternativas de ver y entender estas relaciones (por ejemplo, la relación con animales domésticos). La pertenencia a una u otra especie es un factor fundamental que influye en la posición que cada animal tiene en estas jerarquías asimétricas. Sin embargo, se deben considerar otros elementos relevantes, como los vínculos entre individuos, de la misma manera que el afecto por otras personas depende en líneas generales del tipo de vínculo que tengamos con ellas (por ejemplo, la relaciones familiares o de amistad).

In lieu of an abstract, here is a brief excerpt of the content:Hume and Pascal: Pyrrhonism vs. Nature José R. Maia Neto The view that Pyrrhonism is not practically viable was, according to Richard H. Popkin, held during the seventeenth and eighteenth centuriesbydifferent philosophers suchas Mersenne,Arnauld, Pascal, Ramsay, and others.1 Among the anti-sceptics, this position was usually taken as an argument against Pyrrhonism. Popkin points out that Hume's main contribution to the "Pyrrhonian controversy" is to show that (i) "the (...) Pyrrhonian doctrine was the logical outcome of philosophical analysis,"2 (ii) that the infeasibility of Pyrrhonism does not weaken its epistemological force but only its psychological plausibility, and (Ui) that this implausibility obtains because nature (the common affairs ofeveryday life and the feeUngs, impressions, and ideas thereby generated) impels the philosopher to believe.3 Popkin alsomakes an allusion to the similaritybetweenHume and Pascal on this issue.4 In this paper I compare the dilemma posed by Pascal as apropaedeutic tofaith withthe "dangerous dilemma" alluded to, but avoided, by Hume in the conclusion of book 1 of the Treatise. The dilemma follows from (i) above. At a certain point in his epistemological enquiry the philosopher is forced tomake a hard choice between the quite disadvantageous alternatives: either to continue his philosophizing, which, leading to Pyrrhonism, may bring despair and cause the annihilation ofhis life, or to abandon philosophy, makinghim aprey ofthe "errors, absurdities, andobscurities"ofanon-critical life.5 In what follows I compare Hume's solution to this dilemma with Pascal's.? In the following passage Hume shows the toughness of the dilemma and offers a first answer to it: What party, then, shall we choose among these difficulties? If we... condemn all refin'd reasoning, we run into the most manifest absurdities. If we reject it in favour of these reasonings, we subvert entirely the human understanding. We have, therefore, no choice left but betwixt a false reason and none at all. For my part, I know not what ought to be done Volume XVII Number 1 41 JOSE R.???? NETO in the present case. I can only observe what is commonly done; which is, that this difficulty is seldom or never thought of; and even where it has once been present to the mind, is quickly forgot, and leaves but a small impression behind it. (T 268) Note that in this first answer Hume manages to avoid the normative response that the dilemma demands. He provides, instead, a descriptive account which is a kind of solution because it purports to show that human psychology makes it unlikely that someone could reach the point at which he or she would have to choose between the two parties. The dilemma does not arise because nature stops the self-subversion ofreason. Most fortunately it happens, that since reason is incapable of dispelling these clouds, nature herselfsuffices to that purpose, and cures me of this philosophical melancholy and delirium, either by relaxing this bent ofmind, or by some avocation, and lively impression of my senses, which obliterate all these chimeras. (T 269) Hume means by nature in this passage both human nature and the social and natural environments which, in so far as they demand specific reactions, generate appropriate beliefs. Those beliefs imposed by nature are necessaryforour survival. So, the mere interaction ofthe philosopher with the world outside his closet suffices to dispel his sceptical crisis. According to Hume, this determination of nature is absolute and necessary. "I find myself absolutely and necessarily determin'd to live... I may, nay I must yield to the current ofnature" (T 269). This view is reaffirmed in the Enquiry. Nature is always too strong for principle. And though a PYRRHONIAN may throw himself or others into a momentary amazement and confusion by his profound reasonings; the first and most trivial event in life will put to flight all his doubts and scruples, and leave him the same, in every point ofaction and speculation, with the philosophers of every other sect, or with those who never concerned themselves in any philosophical researches.6 So, it would appear that the dilemma is just a fleeting impression in the imagination of the philosopher during a momentary sceptical crisis. Nature provides that such a crisis is not prolonged... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Academic Skepticism in Early Modern PhilosophyJosé R. Maia NetoAncient skepticism was more influential in the sixteenth and seventeenth centuries than it had ever been before. Thanks to the groundwork of Charles B. Schmitt and Richard H. Popkin on the influence of ancient skepticism in early modern philosophy and to the extensive research that followed their lead, skepticism is now recognized as having played a major role in the rise (...) of modern thought. 1There were two ancient skeptical schools, Academic skepticism and Pyrrhon-ism. Were both equally influential? Until the sixteenth century, Pyrrhonism was scarcely known. Only a few copies of Sextus’s books (the only surviving primary source of ancient Pyrrhonism) have been discovered in medieval libraries. By contrast the main source of Academic skepticism, Cicero’s Aca-demica, was occasionally referred to by medieval authors and was the object of some commentaries and criticism in the Renaissance. 2 Academic skepticism was preserved from the Middle Ages to the Renaissance not only through Cicero’s Academica, but also through Lactantius’s Divinae Institutiones and [End Page 199] Augustine’s Contra Academicos. 3 This situation changed when Sextus’s works were translated to latin and published in 1562 and 1569. Sextus presents a much more complete and detailed account and defense of ancient skepticism than that of Cicero’s Academica. Sextus presents Pyrrhonism as a coherent form of skepticism and Academic skepticism as a kind of negative dogmatism. 4 It was thus natural that the ancient skepticism that fascinated some (and troubled so many) early modern thinkers was mostly Pyrrhonian. Because of the publication of Sextus’s works, according to Schmitt, the increasing influence of Cicero’s Academica in the Renaissance was halted. Sextus’s Hypotyposes and Adversus Mathematicos took the place of Cicero’s Academica and drastically increased the influence of ancient skepticism. 5 The skeptical crisis at the dawn of modern philosophy is called “pyrrhonienne” not “academicienne.”While the appearance of Sextus’s works in Latin turned him and Pyrrhonism into the main source and influence of ancient skepticism in early modern philosophy, further research on the history of skepticism in the period has shown that the role of Cicero’s Academica and of Academic skepticism in general continued to be considerable. First, Cicero’s works were important items in the university curricula. Although Cicero’s works of rhetoric and morals were those more read, the students could certainly learn about Academic skepticism through at least some of them. Second, many editions of De Natura Deorum, a work of Cicero’s in which Academic skepticism is quite central, were published during the seventeenth century. Third, features of Academic skepticism, exhibited above all in Cicero’s Academica, are basic to the skepticism revived in the late Renaissance by Montaigne and Charron; were related to the new science in the first half of the seventeenth century by Gassendi; were used in the anti-Cartesian reaction of the late seventeenth century by Rapin, Huet, Bayle, and above all Foucher; and were radicalized in the eighteenth century by Hume. Despite the Academic features of Montaigne’s, Charron’s, and Gassendi’s skepticisms, it does seem that from the publication of Sextus’s works to the mid-seventeenth century, Academic skepticism was secondary to Pyrrhonism. But the appearance of Descartes and the development of Cartesianism in the second half of the seventeenth century set conditions for a complete revamping of Academic skepticism, bringing about what Schmitt thought was precluded by the appearance of Sextus in the modern scene, namely, a “full flowering of the Academica as a work to inspire new directions of philosophical thought.” 6 [End Page 200]Montaigne’s Apologie pour Raimond Sebond is rightly considered the first major result of the revival of ancient Pyrrhonism in modern thought. 7 Montaigne never cites the name of Sextus nor acknowledges his source and, by contrast, fills his Apology with passages from Cicero on the Academic skeptics. It is clear, however, that Montaigne follows closely Sextus’s Outlines of Pyrrhonism in the central part of the Apology where he gives a detailed and sympathetic exposition of ancient skepticism.After dwelling on the evils and problems arising from knowledge and science, Montaigne...

In this paper we study collective identity functions that deal with formation of clubs. Usually the choice offered to individuals is to cast a vote in favor of qualification or not, and the final outcome is qualification or non-qualification. In this context we show that independent collective identity functions are naturally characterized by voting rules, and in particular, consent rules can be represented by one single collection of weighted majorities. In addition, we consider the extended model where voters are allowed (...) to abstain and we distinguish between disqualification and a neutral outcome. We show that this environment allows agents to act in different capacities that cannot be distinguished in the original formulation of the problem. (shrink)

Ranking finite subsets of a given set X of elements is the formal object of analysis in this article. This problem has found a wide range of economic interpretations in the literature. The focus of the article is on the family of rankings that are additively representable. Existing characterizations are too complex and hard to grasp in decisional contexts. Furthermore, Fishburn (1996), Journal of Mathematical Psychology 40, 64–77 showed that the number of sufficient and necessary conditions that are needed to (...) characterize such a family has no upper bound as the cardinality of X increases. In turn, this article proposes a way to overcome these difficulties and allows for the characterization of a meaningful (sub)family of additively representable rankings of sets by means of a few simple axioms. Pattanaik and Xu’s (1990), Recherches Economiques de Louvain 56, 383–390) characterization of the cardinality-based rule will be derived from our main result, and other new rules that stem from our general proposal are discussed and characterized in even simpler terms. In particular, we analyze restricted-cardinality based rules, where the set of “focal” elements is not given ex-ante; but brought out by the axioms. (shrink)
