In the city of Elche, every year, on the 14th and 15th of August, a sacred musical play about the death, the Assumption and the Coronation of the Virgin Mary is held. This event, known as the “Misterio de Elche”, is unique in the world. Since the middle of the 15th century it has been performed in the Basilica of Santa Maria and in the streets of the ancient city of Elche, located in the Valencian Community. In this work, classified (...) as a UNESCO World Heritage Site, the interior of the temple is transformed into 2 main stages, the scaffold, located in the lower part, and the aerial stage, located in the dome at a height of 27 m. The structure and the traction mechanisms located on the aerial stage allow the aerial devices that take part in the play, “El Araceli”, “La Mangrana” and “La Santísima Trinidad”, to be raised and lowered. It should be noted that between 2 and 5 singing actors are embarked on these devices. This article describes the main characteristics of the aerial stage structure, the 3 apparatus and the mechanical systems used. In addition, the age and modifications of “El Araceli” are analysed, as well as the results of a non-destructive test carried out on this device. (shrink)

This research examines the necessary condition of emotions in predicting consumer ethical decision-making, using a new multiplicative method for identifying and measuring the necessary condition in data sets—Necessary Condition Analysis (NCA). Based on a sample of over four hundred individuals, and combining three different consumption scenarios involving ethical issues, our findings demonstrate that emotions are a necessary condition for consumer ethical decisions and behaviours. In addition, the results show that higher levels of consumer ethical decisions can only be achieved if (...) happiness, gladness and satisfaction increase towards a minimum level of necessity. The findings provide empirical support for the essential role of emotions in predicting consumer ethical decision-making. Furthermore, this research identifies the emotional thresholds without which ethical choices cannot occur and then explains why individuals sometimes behave ethically but other times do not. In addition, this is a first contribution applying NCA to consumer ethics. (shrink)

We welcome a computational theory on social groups, yet we argue it would benefit from a broader scope. A neuroscientific perspective offers the possibility to disentangle which computations employed in a group context are genuinely social in nature. Concurrently, we emphasize that a unifying theory of social groups needs to additionally consider higher-level processes like motivations and emotions.

En este estudio se presentan las líneas directrices de una investigación que se propone analizar el sentido y el significado que se otorga a los conceptos de “bien común” e “interés general” en la retórica de los poderes públicos de nuestro tiempo. A continuación, trata de dar respuesta al interrogante de si ambos conceptos son perfectamente intercambiables en el debate público o, por el contrario, estamos ante conceptos que proceden de presupuestos antagónicos.

The weaver ant, Oecophylla smaragdina Fabricius (Hymenoptera: Formicidae), has long been known as perhaps the first example of human manipulation of a natural predator population to enhance the natural biological control of insect pests. The practice of ant husbandry in Vietnamese citrus orchards and the knowledge associated with the use of weaver ants in the Mekong delta are described. In contrast to other regions of Asia, where weaver ants are noted for their role in the protection of citrus from insect (...) damage, citrus farmers in the Mekong delta explain the benefits of ant husbandry in terms of an improvement in fruit quality, likened to the influence of fertilizers, that occurs in direct response to excretory products deposited by the weaver ants as they patrol the fruit. A series of tests, carried out in 1993–94, rated the external shine, sweetness, juiciness, and overall appeal, as characteristics of fruit quality, for paired comparisons of sweet orange, mandarin, and pummelo fruit that had been grown in the presence of weaver ants or from which ants had been excluded. The tests indicate a strong influence of the presence of the weaver ant on external shine, juiciness, and overall appeal for each of the citrus fruits, but particularly for mandarin. The significance of these results and ant husbandry practices in the Mekong delta are discussed in relation to the development of citrus production in Vietnam. (shrink)

Although pride has been central to philosophical and religious discussions of emotion for thousands of years, it has largely been neglected by psychologists. However, in the past decade a growing body of psychological research on pride has emerged; new theory and findings suggest that pride is a psychologically important and evolutionarily adaptive emotion. In this article we review this accumulated body of research and argue for a naturalist account of pride, which presumes that pride emerged by way of natural selection. (...) In this view, pride is prevalent in human life because of the functional and adaptive role it has played in the attainment, maintenance, and communication of social status throughout our evolutionary history.

In Clark’s thoughtful analysis of the evolution of the two facets of pride, he suggests that the concurrent existence of hubristic and authentic pride in humans represents a “persistence problem,” wherein the vestigial trait (hubristic pride) continues to exist alongside the derived trait (authentic pride). In our view, evidence for the two facets does not pose a persistence problem; rather, hubristic and authentic pride both likely evolved as higher-order cognitive emotions that solve uniquely human—but distinct— evolutionary problems. Instead of being (...) conceptualized as serial homologues, with one the vestigial form of the other, we argue that hubristic and authentic pride are both derived homologues of a vestigial proto-pride emotion that existed in our shared ancestry with other primates.

The Oscar Wilde trials (1895) have usually been interpreted either as a historical document which gives insight into the regulation of sexuality in the late nineteenth century, or as literary biography explicating the playwright's life and works. Taking its cue from recent scholarship in ‘law and literature’, and also from Wilde's own conception of the relationship between art and life, this article proposes a reading of the trials which blurs the distinction between legal history and literary criticism by considering them (...) as a form of literature. It argues that the trial transcripts enact and reflect Wilde's vision of what literature is and how it should be read, and as such should be given a place amongst his literary works, alongside such aesthetic manifestos as ‘The Decay of Lying’ and ‘The Critic as Artist’.

An intermediate stage in Hrushovski’s construction of flat strongly minimal structures in a relational language L produces ω-stable structures of rank ω. We analyze the pregeometries given by forking on the regular type of rank ω in these structures. We show that varying L can affect the isomorphism type of the pregeometry, but not its finite subpregeometries. A sequel will compare these to the pregeometries of the strongly minimal structures.

We investigate the isomorphism types of combinatorial geometries arising from Hrushovski's flat strongly minimal structures and answer some questions from Hrushovski's original paper.

We prove that the category of Nachbin’s compact ordered spaces and order-preserving continuous maps between them is dually equivalent to a variety of algebras, with operations of at most countable arity. Furthermore, we observe that the countable bound on the arity is the best possible: the category of compact ordered spaces is not dually equivalent to any variety of finitary algebras. Indeed, the following stronger results hold: the category of compact ordered spaces is not dually equivalent to any finitely accessible (...) category, any first-order definable class of structures, and any class of finitary algebras closed under products and subalgebras. An explicit equational axiomatisation of the dual of the category of compact ordered spaces is obtained; in fact, we provide a finite one, meaning that our description uses only finitely many function symbols and finitely many equational axioms. In preparation for the latter result, we establish a generalisation of a celebrated theorem by Mundici: our result—whose proof is independent of Mundici’s theorem—asserts that the category of unital commutative distributive lattice-ordered monoids is equivalent to the category of what we call MV-monoidal algebras.Abstract taken directly from the thesis.E-mail: marco[email protected]: https://air.unimi.it/retrieve/handle/2434/812809/1698986/phd_unimi_R11882.pdf.

In this paper, I try to show that Kripke’s proposed solution to the problem of negative existentials fails. I try to show that Kripke’s proposal fails because it entails that anybody who has good reasons to believe that there are no propositions has also good reasons to believe that he or she does not exist. However, there were philosophers who had good reasons to believe that there are no propositions even though they didn’t have good reasons to believe that they (...) do not exist. I conclude that Kripke’s proposed solution to the problem of negative existentials fails. (shrink)

Heterogeneity of Being goes beyond the standard interpretations of Octavio Paz as a thinker of national identity and proposes a radical rethinking of the relationship between literature and philosophy. Dorfsman analyzes how Paz’s “tradition of rupture” properly displays a continuity between self and other, identity and difference, time and space.

This paper discusses how to define logics as deductive limits of sequences of other logics. The case of da Costa's hierarchy of increasingly weaker paraconsistent calculi, known as $ \mathcal {C}$n, 1 $ \leq$ n $ \leq$ $ \omega$, is carefully studied. The calculus $ \mathcal {C}$$\scriptstyle \omega$, in particular, constitutes no more than a lower deductive bound to this hierarchy and differs considerably from its companions. A long standing problem in the literature (open for more than 35 years) is (...) to define the deductive limit to this hierarchy, that is, its greatest lower deductive bound. The calculus $ \mathcal {C}$min, stronger than $ \mathcal {C}$$\scriptstyle \omega$, is first presented as a step toward this limit. As an alternative to the bivaluation semantics of $ \mathcal {C}$min presented thereupon, possible-translations semantics are then introduced and suggested as the standard technique both to give this calculus a more reasonable semantics and to derive some interesting properties about it. Possible-translations semantics are then used to provide both a semantics and a decision procedure for $ \mathcal {C}$Lim, the real deductive limit of da Costa's hierarchy. Possible-translations semantics also make it possible to characterize a precise sense of duality: as an example, $ \mathcal {D}$min is proposed as the dual to $ \mathcal {C}$min. (shrink)

What is mathematics about? And if it is about some sort of mathematical reality, how can we have access to it? This is the problem raised by Plato, which still today is the subject of lively philosophical disputes. This book traces the history of the problem, from its origins to its contemporary treatment. It discusses the answers given by Aristotle, Proclus and Kant, through Frege's and Russell's versions of logicism, Hilbert's formalism, Gödel's platonism, up to the the current debate on (...) Benacerraf's dilemma and the indispensability argument. Through the considerations of themes in the philosophy of language, ontology, and the philosophy of science, the book aims at offering an historically-informed introduction to the philosophy of mathematics, approached through the lenses of its most fundamental problem.

Interest in _dream_ and _madness_, conceived as the loss of a world shared with others, and the individual’s entry into a private world governed by a personal logic unrelated to the waking state and to common feeling, recurs in at least three of Kant’s works: _Essay on the Diseases of the Head,_ (1764), _Dreams of a Spirit-Seer_ (1766), and _Anthropology from a Pragmatic Point of View_ (1798). Hegel too, from an early age, showed a strong fascination and a precocious interest (...) in psychopathological matters (states of altered consciousness, prophetic dreams, somnambulism, catalepsy, witchcraft etc.) to which he devoted intriguing reflections in various works from different periods: from the Berne Ms _Philosophy of Subjective Spirit_ (1794/95) to the _Phenomenology _(1807), from the _Philosophical __Propaedeutics_ (1808ff.) to the _Encyclopedia of the Philosophical Sciences_ (1830 3 ). Starting from the remarks of the two philosophers, this paper aims to underline the conceptual links between their thought and that of some renowned psychologists and psychiatrists of the 1800s-1900s (Pinel, Janet, Adler, James, Binswanger, Freud et al.). On the other hand, the paper also seeks to show – within the framework of an idea of _reason_ dating back to Heraclitus (about 544/483 B.C.) – some murky motifs, not always adequately emphasized in the past, found in the figurative and literary works of the late 1700s (e.g. Fuseli’s_ The Nightmare_, Coleridge’s _The Rhyme of the Ancient Mariner_, and, in particular, plate Nr. 43 of the _Caprichos _by Goya, _El sueño de la razón produce monstruos_), where there emerges a «dark side» of psychic activity emblematically described as the cryptic relationship between _dream_ and_ madness._.

From the early 1840s on, Jeremy Bentham’s utilitarian doctrine aroused the joint interest of Marx and Engels, who saw the English philosopher as one of the forerunners of socialism. Later, however, in the various editions (German, French, English) of Book 1 of Capital (1867/90), Bentham would be sarcastically branded by Marx as a “genius of bourgeois stupidity”. In their youth, both Engels and Marx had independently become interested in Bentham’s ideas, admiring some social-ethical themes, seen as heralding interesting developments for (...) the cause of the proletariat. On Engels’s suggestion, Marx included Bentham’s name, alongside those of the major 18th–19th century English and French exponents of protosocialism, in a planned Library of the most outstanding foreign socialist writers (1845), which however remained only a draft. From his first stay in England (1842/44), the young Engels had embraced in particular the famous utilitarian principle of “the greatest happiness of the greatest number” advocated by Bentham. Marx, on the other hand, after initially praising Bentham’s work, which he had read in a French translation during his exile in Paris (1844), harshly criticized the ambiguous implications of this principle. In fact, he believed thatbehind a misleading progressive façade, it constituted the philosophical equivalent of the later economic theory of labour productivity propounded by D. Ricardo in opposition to the theory of its mere quantitative extension put forward by A. Smith. In the London Manuscripts (1861/63) Marx will reveal the affinity betweenBentham’s principle of the happpiness of the greatest number of people, and Ricardo’s assumption of the ineliminable misery of the minority condemned to productive labour. Based on the collection of Marx’s and Engels’s texts (letters, drafts, notebooks, manuscripts, printed works), made available today thanks to the critical edition by MEGA1, this paper sets out to re-examine, im großen und ganzen, the main moments in their critique of Bentham’s Utilitarianism.

Human adults incline toward moral objectivism but may approach things more relativistically if different cultures are involved. In this study, 4-, 6-, and 9-year-old children (N = 136) witnessed two parties who disagreed about moral matters: a normative judge (e.g., judging that it is wrong to do X) and an antinormative judge (e.g., judging that it is okay to do X). We assessed children’s metaethical judgment, that is, whether they judged that only one party (objectivism) or both parties (relativism) could (...) be right. We found that 9-year-olds, but not younger children, were more likely to judge that both parties could be right when a normative ingroup judge disagreed with an antinormative extraterrestrial judge (with different preferences and background) than when the antinormative judge was another ingroup individual. This effect was not found in a comparison case where parties disagreed about the possibility of different physical laws. These findings suggest that although young children often exhibit moral objectivism, by early school age they begin to temper their objectivism with culturally relative metaethical judgments.

This paper examines the subversive role of statistics paleontology at the end of the 19th and the beginning of the 20th centuries. In particular, I will focus on German paleontology and its relationship with statistics. I argue that in paleontology, the quantitative method was questioned and strongly limited by the first decade of the 20th century because, as its opponents noted, when the fossil record is treated statistically, it was found to generate results openly in conflict with the Darwinian theory (...) of evolution. Essentially, statistics questions the gradual mode of evolution and the role of natural selection. The main objections to statistics were addressed during the meetings at the Kaiserlich-Königliche Geologische Reichsanstalt in Vienna in the 1880s. After having introduced the statistical treatment of the fossil record, I will use the works of Charles Léo Lesquereux, Joachim Barrande, and Henry Shaler Williams to compare the objections raised in Vienna with how the statistical treatment of the data worked in practice. Furthermore, I will discuss the criticisms of Melchior Neumayr, one of the leading German opponents of statistical paleontology, to show why, and to what extent, statistics were questioned in Vienna. The final part of this paper considers what paleontologists can derive from a statistical notion of data: the necessity of opening a discussion about the completeness and nature of the paleontological data. The Vienna discussion about which method paleontologists should follow offers an interesting case study in order to understand the epistemic tensions within paleontology surrounding Darwin’s theory as well as the variety of non-Darwinian alternatives that emerged from the statistical treatment of the fossil record at the end of the 19th century.

Abstract. This paper argues that the “Argument from Moral Peer Disagreement” fails to make a case for widespread moral skepticism. The main reason for this is that the argument rests on a too strong assumption about the normative significance of peer disagreement (and higher-order evidence more generally). In order to demonstrate this, I distinguish two competing ways in which one might explain higher-order defeat. According to what I call the “Objective Defeat Explanation” it is the mere possession of higher-order evidence (...) that explains defeat. I argue that this type of explanation is problematic and that it at best collapses into another explanation I call the “Subjective Defeat Explanation”. According to this explanation, it is coming to believe that one’s belief fails to be rational that explains defeat. Then I go on to argue that the Subjective Defeat Explanation is able to provide a straightforward explanation of higher-order defeat but that it entails that peer disagreement (and higher-order evidence more generally) only contingently gives rise to defeat, and importantly, that the condition it is contingent upon is very often not satisfied when it comes to moral peer disagreement specifically. As a result, it appears that moral knowledge is seldom threatened by moral peer disagreement. (shrink)

Between 1909 and 1913, Berlin’s Museum für Naturkunde unearthed more than 225 tons of fossils in former German East Africa and transported them to Berlin. Among them were the bones of Brachiosaurus brancai, which would eventually become the biggest mounted dinosaur in the world. By analyzing the social and communicative strategies that made this expedition possible, this paper aims to reveal several aspects of natural history knowledge production at the end of the long nineteenth century. Using rhetoric, the director of (...) the Geological–Paleontological Museum in Berlin, Wilhelm von Branca, conducted a highly successful campaign to market the dinosaurs in Prussia and to convince public opinion and the Prussian central state of the value of paleontology. He fired the Prussian imagination and took advantage of the competitive urge to emulate American paleontology and industry. This work examines how his public relations strategies shaped the German biological “landscape” of the first decades of the twentieth century. It asks: when and under what conditions did paleontology successfully appeal to the public? How does communication dictate, shape, and constrain the development of a specific epistemic agenda? And what kind of power do the public and money have? (shrink)

During his celebrated 1922 debate with Bergson, Einstein famously proclaimed: “the time of the philosopher does not exist, there remains only a psychological time that differs from the physicist’s.” Einstein’s dictum, I maintain, has been metabolized by the natural sciences, which typically presuppose, more or less explicitly, the existence of a single, univocal, temporal substratum, ultimately determined by physics. This reductionistic assumption pervades much biological and biomedical practice. The chronological age allotted to individuals is conceived as an objective quantity, allowing (...) one to straightforwardly assign and compare the biological age of organisms. This essay argues that the standard practice of assessing the age and aging of organisms against the backdrop of a physical conception of time is problematic. This becomes especially evident in light of recent discoveries of various levels of senescence underlying the development of individual organisms—a phenomenon known as ‘age mosaicism.’ The bottom line is that the study of age and aging requires a biological conception of time, as opposed to a physical one. Einstein clearly wasn’t wrong about his operationalization of time in relativity theory. Still time may be less monolithic than he surmised. (shrink)

Humans have engaged in artistic and aesthetic activities since the appearance of our species. Our ancestors have decorated their bodies, tools, and utensils for over 100,000 years. The expression of meaning using color, line, sound, rhythm, or movement, among other means, constitutes a fundamental aspect of our species' biological and cultural heritage. Art and aesthetics, therefore, contribute to our species identity and distinguish it from its living and extinct relatives. Science is faced with the challenge of explaining the natural foundations (...) of such a unique trait, and the way cultural processes nurture it into magnificent expressions, historically and ethnically unique. How do the human mind and brain bring about these sorts of behaviors? What psychological and neural processes underlie the appreciation of painting, music, and dance? How does training modulate these processes? Are humans the only species capable of aesthetic appreciation, or are other species endowed with the rudiments of this capacity? Empirical examinations of such questions have a long and rich history in the discipline of psychology, the genesis of which can be traced back to the publication of Gustav Theodor Fechner's Vorschule der Aesthetik in 1876, making it the second oldest branch in experimental psychology. The Oxford Handbook of Empirical Aesthetics brings together leading experts in psychology, neuroimaging, art history, and philosophy to answer these questions. It provides the most comprehensive coverage of the domain of empirical aesthetics to date. With sections on visual art, dance, music, and many other art forms and aesthetic phenomena, the breadth of this volume's scope reflects the richness and variety of topics and methods currently used today by scientists to understand the way our mind and brain endow us with the faculty to produce and appreciate art and aesthetics.

Although ethical decision‐making theory has evolved over the years, within the field of management, research still revolves around James Rest’s (1986) four‐step framework, dominated by a positivist epistemology and a quantitative methodology. Given that currently there is a call for a theoretical, epistemological, and methodological renovation for the enlargement and enrichment of knowledge about how decisions are morally made in organizations, this paper has a double aim. First, by showing the models’ main flaws and limitations, it critically assesses the prominent (...) theoretical models of Rest, Trevino, and Jones. Then, for decision making in organizations, the paper aims to posit a fresh moral theory that addresses the phenomenon from a comprehensive epistemological perspective. To do so, it steps back from those prominent models in order to review John Dewey’s “theory of moral life.” At the core of the proposed comprehensive theoretical framework are Dewey’s concepts of a “moral standard” and “valuation.” Finally, the paper shows how the Dewey‐based framework can both overcome the flaws and limitations that are identified in those prominent models and can enrich empirical research, therefore contributing to developing as a whole the ethical decision‐making field.

One crucial part of the Aristotle´s discussion of the principle of non-contradiction in Metaphysics IV 4 is his notion of semainein hen, which must be carefully distinguished from the closely connected notion of semainein kath´ henos. The Aristotelian proof is located at 1006b28-34 and it is argued that it does not suppose any bit of essentialism nor does it contain any petitio principii; some improvements are further proposed to the current translations.

Husserl’s phenomenology of imagination embraces a cluster of different theories and approaches regarding the multi-faced phenomenon of imaginative experience. In this paper I consider one aspect that seems to be crucial to the understanding of a particular form of imagination that Husserl names pure phantasy. I argue that the phenomenon of Ego-splitting discloses the best way to elucidate the peculiarity of pure phantasy with respect to other forms of representative acts and to any simple form of act modification. First, I (...) unravel the phenomenological distinctions which, respectively, oppose phantasy to perception, on the one hand, and phantasy to other forms of the so-called “intuitive re-presentations”. Second, I introduce the difference between presentative and representative acts, arguing that this cannot help us to single out the defining feature of phantasy experiences. The third section draws again an important distinction between pure phantasy and neutrality modification, which allows me to finally determine an internal trait of phantasy experiences, which Husserl refers to as the “Ego-splitting”. In this way, I hope to contribute to a refined characterization of Husserl’s phenomenology of imagination. (shrink)

This paper offers an introduction to Hermann Cohen’s Das Princip der Infinitesimal-Methode, and recounts the history of its controversial reception by Cohen’s early sympathizers, who would become the so-called ‘Marburg school’ of Neo-Kantianism, as well as the reactions it provoked outside this group. By dissecting the ambiguous attitudes of the best-known representatives of the school, as well as those of several minor figures, this paper shows that Das Princip der Infinitesimal-Methode is a unicum in the history of philosophy: it represents (...) a strange case of an unsuccessful book’s enduring influence. The “puzzle of Cohen’s Infinitesimalmethode,” as we will call it, can be solved by looking beyond the scholarly results of the book, and instead focusing on the style of philosophy it exemplified. Moreover, the paper shows that Cohen never supported, but instead explicitly opposed, the doctrine of the centrality of the ‘concept of function’, with which Marburg Neo-Kantianism is usually associated.

Proposition I.1 is, by far, the most popular example used to justify the thesis that many of Euclid’s geometric arguments are diagram-based. Many scholars have recently articulated this thesis in different ways and argued for it. My purpose is to reformulate it in a quite general way, by describing what I take to be the twofold role that diagrams play in Euclid’s plane geometry (EPG). Euclid’s arguments are object-dependent. They are about geometric objects. Hence, they cannot be diagram-based unless diagrams (...) are supposed to have an appropriate relation with these objects. I take this relation to be a quite peculiar sort of representation. Its peculiarity depends on the two following claims that I shall argue for: ( i ) The identity conditions of EPG objects are provided by the identity conditions of the diagrams that represent them; ( ii ) EPG objects inherit some properties and relations from these diagrams.

This essay pushes the history of a scientific discipline, morphology, toward a broader philosophically informed and cross-disciplinarily engaged history of knowledge. It shows that by looking at how knowledge and practices circulated between scientific disciplines (such as biology) and technoscientific ones (like architecture and design) we can better understand how (morphological) knowledge was produced. By doing so, the analysis contributes to the study of the mechanisms of knowledge exchange between the organic and the technical worlds and, more broadly, to the (...) study of the dynamics of knowledge circulation. First, the essay analyzes the engineering studies of organic form conducted by the Austro-Hungarian botanist Raoul Heinrich Francé (1874–1943) and the Scottish polymath D’Arcy Wentworth Thompson (1860–1948). Subsequently, the essay moves to twenty-first-century morphogenesis. It examines the transfer of the notion of morphospace, a paleontological practice of data visualization, into biology-inspired architectural design. The conclusion deals with the broader features of knowledge transfer and circulation. Twentieth- and twenty-first-century morphologists successfully translate and transfer morphogenetic processes from nature into technical artifacts to achieve technical solutions to given problems. In the translation of organic morphogenesis into a technical process, evolution’s intrinsic historical contingency was deliberately left behind. (shrink)

The paper offers a historical overview of Einstein's oscillating attitude towards a "phenomenological" and "dynamical" treatment of rods and clocks in relativity theory. Contrary to what it has been usually claimed in recent literature, it is argued that this distinction should not be understood in the framework of opposition between principle and constructive theories. In particular Einstein does not seem to have plead for a "dynamical" explanation for the phenomenon rods contraction and clock dilation which was initially described only "kinematically". (...) On the contrary textual evidence shows that, according to Einstein, a realistic microscopic model of rods and clocks was needed to account for the very existence of measuring devices of "identical construction" which always measure the same unit of time and the same unit of length. In fact, it will be shown that the empirical meaningfulness of both relativity theories depends on what, following Max Born, one might call the "principle of the physical identity of the units of measure". In the attempt to justify the validity of such principle, Einstein was forced by different interlocutors, in particular Hermann Weyl and Wolfgang Pauli, to deal with the genuine epistemological, rather then physical question whether a theory should be able or not to described the material devices that serve to its own verification.

This paper focuses on two passages of Aristotle’s Metaphysics, one in Z 3, the other in H1, in which Aristotle seems to assert that the hupokeimenon is said in three ways, as matter, form, and the compound of matter and form. From these two passages it is often said that subjecthood is a criterion for being substance. A consequence of this is that, if form is to be substance, and form is substance, namely first substance, it has to comply with (...) the subject-criterion. This paper challenges this reading, purporting to show that these two passages need not commit Aristotle to the subject-criterion, and that there are good reasons not to commit him to it. (shrink)
