The avocado (Persea americana) is a major crop commodity worldwide. Moreover, avocado, a paleopolyploid, is an evolutionary “outpost” among flowering plants, representing a basal lineage (the magnoliid clade) near the origin of the flowering plants themselves. Following centuries of selective breeding, avocado germplasm has been characterized at the level of microsatellite and RFLP markers. Nonetheless, little is known beyond these general diversity estimates, and much work remains to be done to develop avocado as a major subtropical‐zone crop. Among the goals (...) of avocado improvement are to develop varieties with fruit that will “store” better on the tree, show uniform ripening and have better post‐harvest storage. Avocado transcriptome sequencing, genome mapping and partial genomic sequencing will represent a major step toward the goal of sequencing the entire avocado genome, which is expected to aid in improving avocado varieties and production, as well as understanding the evolution of flowers from non‐flowering seed plants (gymnosperms). Additionally, continued evolutionary and other comparative studies of flower and fruit development in different avocado strains can be accomplished at the gene expression level, including in comparison with avocado relatives, and these should provide important insights into the genetic regulation of fruit development in basal angiosperms.

What makes a human voice agreeable is a matter of scientific discussion. Whereas prosody was shown to play a role regarding “male-female” attraction, the impact of frequency modulations in “non-sexual”, notably commercial, contexts has attracted little attention. Another point unaddressed in the literature is auditory sensitivity to short-term frequency modulations as current studies focus more on sentence. Thirty French female operators were recorded over the phone. All “bonjour” greeting words were classified in terms of frequency modulation linearity and orientation at (...) the syllable and word levels. Then, the different voices were played back to students and seniors who had to rate each voice according to their degree of agreeableness. Listeners preferred non-monotonous voices. Differences between age-classes were greater than between sex-classes. Results suggest that short-term frequency changes are important for auditory evaluation of voice agreeableness. This study opens new research perspectives concerning the importance of prosody during consumer-seller interactions. (shrink)

Notre science ne saurait être qu’inachevable et infondable. Qu’implique cette situation du discours scientifique selon Pascal? Et quelles significations, existentielles et épistémologiques, accorder au recours inévitable à la « nature »? En quoi la nature est-elle en nous relais du discours?

La notion d’expérience transcendantale correspond dans l’œuvre de Husserl à une reprise radicalement nouvelle du projet classique d’une philosophie première, autre terme employé pour désigner la métaphysique en tant que recherche sur le sens de l’être et sur les principes premiers de sa connaissance. Une telle notion correspond très précisément à ce que Husserl appelle la réflexion phénoménologique transcendantale. Dans ses Méditations cartésiennes, il en livre à la fois le projet et la signi...

It is held by many philosophers that it is a consequence of epistemic contextualism that speakers are typically semantically blind, that is, typically unaware of the propositions semantically expressed by knowledge attributions. In his ?Contextualism, Invariantism and Semantic Blindness? (this journal, 2009), Martin Montminy argues that semantic blindness is widespread in language, and not restricted to knowledge attributions, so it should not be considered problematic. I will argue that Montminy might be right about this, but that contextualists still face a (...) serious and related problem: that it is a consequence of epistemic contextualism that subjects are typically unaware of contents conveyed by knowledge attributions, independently of whether these are semantic or non-semantic contents. Even if semantic blindness is widespread in language, it does not seem that content unawareness of this sort is. (shrink)

The land has come Into its own. At last it has become the focus of great national problems which until now were evoked most frequently with regard to and for the benefit of cities, or even of metropolitan areas. Its very representation, until very recent ages held to be terribly abstract and reserved to technicians, today belongs to the public domain. Exhibitions bearing titles such as Maps and Illustrations of the Earth (Paris, 1980) or Landscape: Image and Reality (Bologna, 1981) (...) attract as many visitors as an Impressionist retrospective, not only because of the novelty of the theme, the rarity of certain documents or the beauty of most of them, as proven by the success of even more specialized events such as those dedicated to the 1730 Sardinian cadastre in Savoy or to the one of Maria-Theresa in Lombardy (Chambéry and Pavia, 1980).

It is widely believed by philosophers that we human beings are capable of stepping back from inclinations to act in a certain way and consider whether we should do so. If we judge that there are enough reasons in favour of following our initial inclination, we are definitely motivated, and, if all goes well, we act. This view of human agency naturally leads to the idea that our actions are self-determined, or controlled by ourselves. Some go one step further to (...) the point of saying that we should extend the fundamental aspects of this view of human agency to the epistemic realm. This we call ‘the control-view”. Here we will make a strong case against the control-view. While we have a substantial control over our practical lives, it is very unlikely that this extends to our epistemic lives. Our discussion will proceed in three stages. We will present two asymmetries between our practical and epistemic lives which are followed by a general argument against the control-view. (shrink)

This book presents a comprehensive and detailed exploration of the relationship between the thought of G.W.F. Hegel and that of John McDowell, the latter of whom is widely considered to be one of the most influential living analytic philosophers. It serves as a point of entry in McDowell’s and Hegel’s philosophy, and a substantial contribution to ongoing debates on perceptual experience and perceptual justification, naturalism, human freedom and action. The chapters gathered in this volume, as well as McDowell’s responses, make (...) it clear that McDowell’s work paves the way for an original reading of Hegel’s texts. His conceptual framework allows for new interpretive possibilities in Hegel’s philosophy which, until now, have remained largely unexplored. Moreover, these interpretations shed light on various aspects of continuity and discontinuity between the philosophies of these two authors, thus defining more clearly their positions on specific issues. In addition, they allow us to see Hegel’s thought as containing a number of conceptual tools that might be useful for advancing McDowell’s own philosophy and contemporary philosophy in general.

In this challenging study, André Gallois proposes and defends a thesis about the character of our knowledge of our own intentional states. Taking up issues at the centre of attention in contemporary analytic philosophy of mind and epistemology, he examines accounts of self-knowledge by such philosophers as Donald Davidson, Tyler Burge and Crispin Wright, and advances his own view that, without relying on observation, we are able justifiably to attribute to ourselves propositional attitudes, such as belief, that we consciously (...) hold. His study will be of wide interest to philosophers concerned with questions about self-knowledge. (shrink)

In his Perception and Reason, Bill Brewer argues that one can only have empirical beliefs if one’s perceptual experiences serve as reasons for such beliefs. His argument for this idea relies on a premise according to which in order for the relations with perceptual experience to determine the contents of empirical beliefs, these relations must be reason-giving. He offers an argument for this premise, the so-called Switching Argument. In this paper, I show that the Switching Argument does not work, in (...) which case we have no reason to accept the premise the argument is supposed to establish, and hence no reason to accept Brewer’s argument in favour of the idea that one can only have empirical beliefs if one’s perceptual experiences serve as reasons for such beliefs.

Podemos ver na ausência de luz, e ouvir na ausência de som? Em seu livro Seeing Dark Things: The Philosophy of Shadows (2008), Roy Sorensen defende que sim, que podemos ver a escuridão na ausência de luz, e ouvir o silêncio na ausência de som. Neste artigo, defendo que na escuridão nada vemos, no silêncio nada ouvimos, e que experienciar a ausência de luz e som é uma questão afetiva, e não perceptual.

This article considers the origins of alphabetic writing, tracing its probable source to ancient Egypt, southern Levant or the Sinai during the Egyptian Middle Kingdom (17th century BCE). It supports the view that the earliest scripts were acrophonic representations of a West-Semitic language, whose use developed under the rule of the Hyksos in Egypt but was arrested there with the expulsion of this foreign dynasty at the end of the 16th century BCE. The development is then traced through the Levant, (...) with particular attention given to the emergence of cuneiform alphabetic scripts in Ugarit (c. 1300 BCE). This form of writing disappeared with the fall of Ugarit, but linear alphabetic scripts were preserved in a variety of Near-Eastern languages, notably Aramaic and Phoenician. These two languages, by becoming linguae francae respectively of the Syria-northern Mesopotamia and the Anatolia-Eastern Mediterranean regions, brought about the spread of alphabetic writing up until the 8th century BCE. The article concludes by examining the influence of the Phoenician script on Greek, Etruscan and ultimately Latin forms of writing. (shrink)

Prudential hedonism has been beset by many objections, the strength and number of which have led most modern philosophers to believe that it is implausible. One objection in particular, however, is nearly always cited when a philosopher wants to argue that prudential hedonism is implausible—the experience machine objection to hedonism. This paper examines this objection in detail. First, the deductive and abductive versions of the experience machine objection to hedonism are explained. Following this, the contemporary responses to each version of (...) the argument are assessed and the deductive version is argued to be relatively ineffective compared to the abductive version. Then, a taxonomy of the contemporary critical responses to the abductive version is created. Consideration of these responses shows that the abductive version of the objection is fairly powerful, but also that one type of response seems promising against it. This response argues that experience machine thought experiments seem to elicit judgments that are either too biased to be used as evidence for the objection or not obviously in favour of reality. It is argued that only this type of refutation seems likely to convince proponents of the abductive version that the objection is much weaker than they believe it to be. Finally, it is suggested that more evidence is required before anything definitive can be said on the matter. (shrink)

The philosophy problem of identity and the related problem of change go back to the ancient Greek philosophers and fascinated later figures including Leibniz, Locke and Hume. Heraclitus argued that one could not swim in the same river twice because new waters were ever flowing in. When is a river not the same river? If one removes one plank at a time when is a ship no longer a ship? What is the basic nature of identity and persistence? This book (...) introduces and asseses the philosophical puzzles posed by things persisting through time. Beginning with essential historical background to the problem it explores the following key topics and debates: mereology and identity, including 'Leibniz's Law' the constitution view of identity the 'relative identity' argument concerning identity temporary identity four-dimensionalism, counterpart and mulitiple counterpart theory supervenience the problem of temporary intrinsics the necessity of identity presentism ontological and epistemological criteria for persistence and the difference between them. Including chapter summaries, annotated further reading and a glossary this book is essential reading for anyone seeking a clear and informative introduction to and assessement of the metaphysics of identity.

Within the context of exploring new electronic arts' aesthetic regions and unexampled connections between generative art, games and mythology, my practical artistic research was led to focus on labyrinthine structures as exquisite legendary spatial gaming devices and as possible pathways to gain deeper humane insights, resulting into discoveries of original methods of labyrinth formation by means other than human. Labyrinths and mazes are inextricable paths, human made millennial structures that provide spatial challenges often connected with feedback, compression, entanglement and hyper (...) complexification of goal oriented displacement. They are perhaps the most ancient example of structure for spatial and serious games. Novel methods for labyrinth creation ‐ non-human methods ‐ are introduced and exemplified through artistic constructs. These new methods utilize non-human bioelectronic techniques and are initially grouped into three distinct sub-categories: the 'open' method, the 'mathematical flower' method, the 'animal' method. Four case examples of artistic non-human labyrinths resorting to the introduced novel methods are explored: k. video games (2007, 2010), Wolfanddotcom video game (2017), 8-bit Maze Gardens vegetable paintings (2018‐present), Ant Ennae Labyrinths bio-electronic apparatus (2019‐present).

This reconsideration of Hume’s classic essay “Of Miracles” via the lens of American pragmatist ways of thinking about history and power shifts our attention from Hume’s epistemic concerns about the legitimacy of witnesses and testimony to his distaste for sacred history, his critical stance regarding the social force of revelation, and his disdain for religious authority. To view Hume’s essay both as an articulation of a critical philosophy of history and as an exercise in moral dynamism (social power or, authority, (...) is a result of epistemic transactions), is to intervene in both Hume studies and Contemporary Pragmatism.

Pierre André,Michel Bourban | : Dans un contexte d’urgence, les philosophes ne peuvent plus se contenter d’élaborer des théories idéales de la justice climatique fondées sur des motivations purement morales. Il est désormais nécessaire d’envisager des approches non idéales. Nous proposons ici de prendre au sérieux le problème de la motivation à l’action et nous mettons en avant certains motifs prudentiels pour lutter contre le changement climatique, en vue non pas de remplacer, mais de renforcer les motivations morales existantes, (...) mais insuffisantes. Nous commençons par présenter trois grandes approches idéales qui ont prévalu jusqu’ici dans la recherche sur la justice climatique et sont fondées respectivement sur l’éthique déontologique, sur l’éthique des vertus et sur l’utilitarisme. Nous mettons en évidence leurs limites pratiques, en ciblant le problème de la motivation à l’action. Nous proposons ensuite quelques pistes pour résoudre ce problème en esquissant une approche non idéale de la justice climatique. Cette approche est centrée sur les motivations amorales ressortant de l’examen attentif des perturbations systémiques globales et des contextes nationaux et locaux spécifiques. Elle est à notre sens incontournable pour motiver les États-nations, les entreprises et les individus. Il s’agit cependant moins de la substituer totalement aux théories idéales de la justice climatique que de compléter celles-ci pour établir une vision plus compréhensive qui distingue le problème de la justification morale de celui de la motivation. | : In a situation of urgency, philosophers can no longer rely exclusively on ideal theories of climate justice grounded on purely moral motives. It has become necessary to build nonideal approaches. We propose to give serious consideration to the problem of motivation to act by putting forward some prudential reasons for tackling climate change—with the aim not of replacing existing but inadequate moral motivations, but of strengthening them. First, we identify three major ideal approaches that have so far prevailed in climate justice research, grounded respectively on deontological ethics, on virtue ethics, and on utilitarianism. We highlight their practical limitations, particularly with regards to the problem of motivation to act. Second, we open the way for an alternative nonideal approach to climate justice based on amoral motivations issuing from a careful examination of global systemic disruptions as well as of specific national and local situations. This approach cannot be ignored if one wishes to motivate nation-states, corporations, and individuals to act. However, our goal is not to replace ideal theory with nonideal theory, but rather to complete the former with the latter for a more comprehensive account of climate justice that distinguishes the problem of moral justification from the problem of motivation.

This paper intends to recover the “phenomenological” basis of Sartre’s trajectory since his very first reception of Edmund Husserl’s and Martin Heidegger’s philosophies until the moment in which the main synthesis of his existentialism is published, entitled Being and Nothingness (1943). In this sense, the paper situates the status of Husserl’s and Heidegger’s phenomenologies for Sartrean thought, as well as the originality of Being and Nothingness, which is also influenced by a very particular interpretation of Hegelian negation.

Andre Jean Festugiere (1898-1982) a ete directeur d'etudes a l'Ecole pratique des Hautes Etudes de 1943 a 1968. C'est pendant cette longue periode qu'il a donne une formidable impulsion, a Paris, aux etudes consacrees a l'Antiquite tardive Naturellement c'est aussi par ses publications nombreuses que le Pere Festugiere a contribue au rayonnement international de l'histoire de la philosophie a la fin du paganisme. On peut recenser 73 livres et 277 articles de revues et comptes rendus de livres. A la fin (...) de sa vie, il a reuni les plus importants de ses articles disperses en trois volumes. En 1971, ce furent les Etudes de philosophie grecque, en 1972, les Etudes de religion grecque et hellenistique et en 1975, les Etudes d'histoire et de philologie. Voici la reimpression des Etudes de philosophie grecque, qu'il a divisees en trois parties: d'abord les problemes generaux, puis les problemes de detail, enfin les Procliana. Les problemes de detail traitent ou bien de notions (eternite, endurance, peche) ou bien de questions particulieres posees par les ecrits de Platon, d'Aristote, de Theophraste, de Galien, d'Aristide Quintilien, ou d'expressions obscures dont le sens est devoile, tandis que les problemes generaux s'attaquent au probleme du mal, a celui du plaisir, aux rapports des philosophes grecs avec les sages orientaux et l'Inde, au systeme d'Aristote et aux genres de vie active et contemplative dans le monde greco-romain. Par la lecture de ces articles, le Pere Festugiere continue et continuera longtemps encore a enseigner ses lecteurs. (shrink)

My topic is extraterrestrial intelligence. Following current conventions, I use the abbreviation ‘ETI’ to stand for three related concepts: the abstract idea of extraterrestrial intelligence, individuals who are both extraterrestrial and intelligent, and the hypothesis that there are ETIs. SETI is the search for ETIs, and CETI is the attempt to communicate with ETIs. In this paper, I will try to answer the two most basic questions in extraterrestrial studies. First, what is the status of the ETI hypothesis? In the (...) light of what we know, how likely is it that there are ETIs? Secondly, what is the value of pursuing SETI? Are the expected epistemic and pragmatic payoffs sufficient to warrant an extensive search? The first, substantive question is discussed in Section 2, Section 3 and Section 4. The second, ‘program evaluation’ question is the subject of Section 5 and Section 6. But first we'll take a brief look at some of the early history of the topic. (shrink)

The biinterpretability conjecture for the r.e. degrees asks whether, for each sufficiently large k, the [Formula: see text] relations on the r.e. degrees are uniformly definable from parameters. We solve a weaker version: for each k ≥ 7, the [Formula: see text] relations bounded from below by a nonzero degree are uniformly definable. As applications, we show that Low 1 is parameter definable, and we provide methods that lead to a new example of a ∅-definable ideal. Moreover, we prove that (...) automorphisms restricted to intervals [d, 1], d ≠ 0, are [Formula: see text]. We also show that, for each c ≠ 0, can be interpreted in [0, c] without parameters.

With each proposition P we associate a set of proposition (a hyperproposition) which determines the order in which one may retreat from accepting P, if one cannot fully hold on to P. We first describe the structure of hyperpropositions. Then we describe two operations on propositions, subtraction and merge, which can be modelled in terms of hyperpropositions. Subtraction is an operation that takes away part of the content of a proposition. Merge is an operation that determines the maximal consistent content (...) of two propositions considered jointly. The merge operation gives rise to an inference relation which is, in a certain sense, optimally paraconsistent. (shrink)

Judith Andre examines the issue of the scope of the market.

To solve the probability problem of the Many Worlds Interpretation of Quantum Mechanics, D. Wallace has presented a formal proof of the Born rule via decision theory, as proposed by D. Deutsch. The idea is to get subjective probabilities from rational decisions related to quantum measurements, showing the non-probabilistic parts of the quantum formalism, plus some rational constraints, ensure the squared modulus of quantum amplitudes play the role of such probabilities. We provide a new presentation of Wallace’s proof, reorganized to (...) simplify some arguments, and analyze it from a formal perspective. Similarities with classical decision theory are made explicit, to clarify its structure and main ideas. A simpler notation is used, and details are filled in, making it easier to follow and verify. Some problems have been identified, and we suggest possible corrections. (shrink)

We consider motivations for acknowledging that people participate in multiple levels of economic agency. One of these levels is characterized in terms of subjective utility to the individual; another, frequently observed, level is characterized in terms of utility to social groups with which people identify. Following Bacharach, we describe such groups as ‘teams’. We review Bacharach’s theory of such identification in his account of ‘team reasoning’. While this conceptualization is useful, it applies only to processes supported by deliberation. As this (...) is only one of a range of causal mechanisms underlying behaviour by humans and other strategic agents, a more general account is desirable. We then argue that Stirling’s account of ‘conditional games’ achieves the desired generalization. (shrink)

Most professionals have the arduous task of managing their own dual loyalty: in one contextual relationship, they are members of a profession while simultaneously they are employed as members of a locally established organisation. This sense of a dual loyalty has to be taken into account when professional bureaucracies develop ethics programmes. This article focuses on universities. Accounting for the dual loyalty of academic professionals, it is the objective of the study to contribute to the most appropriate ethics programmes in (...) such an academic context. Based on a review of the literature, we identify which ethical issues commonly emerge in educational and research activities. Then we offer a conceptual analysis of the conditions required for each different strategy of ethics management. We argue that none of the four theoretically derived strategies is applicable solely on its own. For universities it is most promising to design ethics programmes based on the guiding values of the academic community, including integrity measures for universities and corrective measures for students. The argument developed in this article is assumed to be widely applicable in assessing the appropriateness of ethics management strategies in other professional settings. (shrink)
