  2. A Case for an Empirically Demonstrable Notion of the Vacuum in Quantum Electrodynamics Independent of Dynamical Fluctuations.Mario Bacelar Valente - 2011 - Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 42 (2):241-261.
    A re-evaluation of the notion of vacuum in quantum electrodynamics is presented, focusing on the vacuum of the quantized electromagnetic field. In contrast to the ‘nothingness’ associated to the idea of classical vacuum, subtle aspects are found in relation to the vacuum of the quantized electromagnetic field both at theoretical and experimental levels. These are not the usually called vacuum effects. The view defended here is that the so-called vacuum effects are not due to the ground state of the quantized (...)

  3. Ancient Greek Mathematical Proofs and Metareasoning.Mario Bacelar Valente - 2024 - In Maria Zack (ed.), Research in History and Philosophy of Mathematics. Annals of the Canadian Society for History and Philosophy of Mathematics. pp. 15-33.
    We present an approach in which ancient Greek mathematical proofs by Hippocrates of Chios and Euclid are addressed as a form of (guided) intentional reasoning. Schematically, in a proof, we start with a sentence that works as a premise; this sentence is followed by another, the conclusion of what we might take to be an inferential step. That goes on until the last conclusion is reached. Guided by the text, we go through small inferential steps; in each one, we go (...)

  4. Communicating and Disagreeing with Distinct Concepts: A Defense of Semantic Internalism.Matheus Valente - 2019 - Theoria 85 (4):312-336.
    I suggest a solution to a conflict between semantic internalism – according to which the concepts one expresses are determined by one's use of representations – and publicity – according to which, if two subjects successfully communicate or are in genuine agreement, then they entertain thoughts constituted by the same concepts. My solution rests on the thesis that there can be successful communication and genuine agreement between thinkers employing distinct concepts as long as there is a certain relation (of conceptually (...)

  5. Longevity and Age-Group Justice.Manuel Sá Valente - 2023 - Law, Ethics and Philosophy 10 (10):96-113.
    Justice Across Ages offers an attractive account of justice between the young and the old that brings together three notable principles of age-group justice: complete-lives equality, relational equality, and prudence. Yet, the book says little about the fact that many of us live longer than others, and the little it does say casts doubt on whether lifespan inequality threatens justice as construed by the three principles. This essay argues, instead, that theories of justice between the young and the old should (...)

  6. Difficult Circumstances: Situationism and Ability.Marcela Herdova & Stephen Kearns - 2019 - Journal of Ethical Urban Living 2 (1):63-91.
    Certain aspects of our situations often influence us in significant and negative ways, without our knowledge (call this claim “situationism”). One possible explanation of their influence is that they affect our abilities. In this paper, we address two main questions. Do these situational factors rid us of our abilities to act on our sufficient reasons? Do situational factors make it more difficult for us to exercise our abilities to act for sufficient reasons? We argue for the answer ‘sometimes’ to both (...)

  7. A Puzzle about Communication.Matheus Valente & Andrea Onofri - 2023 - Review of Philosophy and Psychology 14 (3):1035-1054.
    It seems plausible that successfully communicating with our peers requires entertaining the same thoughts as they do. We argue that this view is incompatible with other, independently plausible principles of thought individuation. Our argument is based on a puzzle inspired by the Kripkean story of Peter and Paderewski: having developed several variations of the original story, we conclude that understanding and communication cannot be modeled as a process of thought transfer between speaker and hearer. While we are not the first (...)

  8. Einstein's redshift derivations: its history from 1907 to 1921.Mario Bacelar Valente - 2018 - Circumscribere: International Journal for the History of Science 22:1-16.
    Einstein's gravitational redshift derivation in his famous 1916 paper on general relativity seems to be problematic, being mired in what looks like conceptual difficulties or at least contradictions or gaps in his exposition. Was this derivation a blunder? To answer this question, we will consider Einstein’s redshift derivations from his first one in 1907 to the 1921 derivation made in his Princeton lectures on relativity. This will enable to see the unfolding of an interdependent network of concepts and heuristic derivations (...)

  9. On Successful Communication, Intentions and False Beliefs.Matheus Valente - 2021 - Theoria 87 (1):167-186.
    I discuss a criterion for successful communication between a speaker and a hearer put forward by Buchanan according to which there is communicative success only if the hearer entertains, as a result of interpreting the speaker's utterance, a thought that has the same truth conditions as the thought asserted by the speaker and, furthermore, does so in virtue of recognizing the speaker's communicative intentions. I argue, against Buchanan, that the data on which it is based are compatible with a view (...)

  10. What is special about indexical attitudes?Matheus Valente - 2018 - Inquiry: An Interdisciplinary Journal of Philosophy 61 (7):692-712.
    In this paper, I assess whether indexical attitudes, e.g. beliefs and desires, have any special properties or present any special challenge to theories of propositional attitudes. I being by investigating the claim that allegedly problematic indexical cases are just instances of the familiar phenomenon of referential opacity. Regardless of endorsing that claim, I provide an argument to the effect that indexical attitudes do have a special property. My argument relies on the fact that one cannot account for what is it (...)

  11. Working Retirees? A Liberal Case for Retirement as Free Time.Manuel Sá Valente - forthcoming - Ethical Theory and Moral Practice:1-15.
    Retirement is often viewed as a reward for a working life. While many have reason to want a work-free retirement, not everyone does. Should working retirees have to give up their retirement pension and, consequently, their status as retirees? The answer, I argue, boils down to whether we conceive of retirement as free time (need-free) or as leisure (work-free). In this article, I put forward a liberal case in favour of free time, despite whether our liberalism leans towards perfectionism or (...)

    in this paper we return to Marshall Clagett’s view about the existence of an ancient Greek geometry of motion. It can be read in two ways. As a basic presentation of ancient Greek geometry of motion, followed by some aspects of its further development in landmark works by Galileo and Newton. Conversely, it can be read as a basic presentation of aspects of Galileo’s and Newton’s mathematics that can be considered as developments of a geometry of motion that was first (...)

  13. The Faithfulness Problem.Mario Bacelar Valente - 2022 - Principia: An International Journal of Epistemology 26 (3):429-447.
    When adopting a sound logical system, reasonings made within this system are correct. The situation with reasonings expressed, at least in part, with natural language is much more ambiguous. One way to be certain of the correctness of these reasonings is to provide a logical model of them. To conclude that a reasoning process is correct we need the logical model to be faithful to the reasoning. In this case, the reasoning inherits, so to speak, the correctness of the logical (...)

  14. Perverted Space-Time Geodesy in Einstein’s Views on Geometry.Mario Bacelar Valente - 2018 - Philosophia Scientiae 22:137-162.
    A perverted space-time geodesy results from the idea of variable rods and clocks, whose length and rates are taken to be affected by the gravitational field. By contrast, what we might call a concrete geodesy relies on the idea of invariable unit-measuring rods and clocks. Indeed, this is a basic assumption of general relativity. Variable rods and clocks lead to a perverted geodesy, in the sense that a curved space-time may be seen as a result of a departure from the (...)

    Get Old or Die Trying: Longevity Justice in Social Insurance.Manuel Sá Valente - forthcoming - Politics, Philosophy and Economics.
    Of all the risks we face in life, ranging from unemployment to old age, early death is among the most tragic and yet most neglected by modern states. Liberal egalitarians might find it easy to dismiss social insurance against early death, but I argue they should not. Early in this paper, I explain why social insurance should include the risk of premature death by replying to four common criticisms. What follows is a case for a novel form of insurance that (...)

  16. A hub-and-spoke model of geometric concepts.Mario Bacelar Valente - 2023 - Theoria : An International Journal for Theory, History and Fundations of Science 38 (1):25-44.
    The cognitive basis of geometry is still poorly understood, even the ‘simpler’ issue of what kind of representation of geometric objects we have. In this work, we set forward a tentative model of the neural representation of geometric objects for the case of the pure geometry of Euclid. To arrive at a coherent model, we found it necessary to consider earlier forms of geometry. We start by developing models of the neural representation of the geometric figures of ancient Greek practical (...)

  17. On the correctness of problem solving in ancient mathematical procedure texts.Mario Bacelar Valente - 2020 - Revista de Humanidades de Valparaíso 16:169-189.
    It has been argued in relation to Old Babylonian mathematical procedure texts that their validity or correctness is self-evident. One “sees” that the procedure is correct without it having, or being accompanied by, any explicit arguments for the correctness of the procedure. Even when agreeing with this view, one might still ask about how is the correctness of a procedure articulated? In this work, we present an articulation of the correctness of ancient Egyptian and Old Babylonian mathematical procedure texts – (...)

  18. From practical to pure geometry and back.Mario Bacelar Valente - 2020 - Revista Brasileira de História da Matemática 20 (39):13-33.
    The purpose of this work is to address the relation existing between ancient Greek practical geometry and ancient Greek pure geometry. In the first part of the work, we will consider practical and pure geometry and how pure geometry can be seen, in some respects, as arising from an idealization of practical geometry. From an analysis of relevant extant texts, we will make explicit the idealizations at play in pure geometry in relation to practical geometry, some of which are basically (...)

    The purpose of this work is to address what notion of geometrical object and geometrical figure we have in different kinds of geometry: practical, pure, and applied. Also, we address the relation between geometrical objects and figures when this is possible, which is the case of pure and applied geometry. In practical geometry it turns out that there is no conception of geometrical object.

  20. Do all languages share the same conceptual structure?Mario Bacelar Valente - 2022 - Cognitive Semantics 8 (2):159-180.
    In this work, we consider the views of three exponents of major areas of linguistics – Levelt (psycholinguistics), Jackendoff (theoretical linguistics), and Gil (field linguistics) – regarding the issue of the universality or not of the conceptual structure of languages. In Levelt’s view, during language production, the conceptual structure of the preverbal message is language-specific. In Jackendoff’s theoretical approach to language – his parallel architecture –, there is a universal conceptual structure shared by all languages, in contradiction to Levelt’s view. (...)

  21. Ageing as Equals: Distributive Justice in Retirement Pensions.Manuel Sá Valente - 2022 - Dissertation, Université Catholique de Louvain
    Despite being increasingly available to us all, retirement pensions remain unequally distributed: between rich and poor, young and old, men and women, and possibly different generations. As this topic receives little attention in moral and political philosophy, the articles in this thesis aim to deliver an original account of justice in retirement pensions along liberal egalitarian lines. The first part defends retirement pensions as a distribution of free time. It shows that including free time in the list of goods that (...)

  22. On the relationship between geometric objects and figures in Euclidean geometry.Mario Bacelar Valente - 2021 - In Diagrammatic Representation and Inference. 12th International Conference, Diagrams 2021. pp. 71-78.
    In this paper, we will make explicit the relationship that exists between geometric objects and geometric figures in planar Euclidean geometry. That will enable us to determine basic features regarding the role of geometric figures and diagrams when used in the context of pure and applied planar Euclidean geometry, arising due to this relationship. By taking into account pure geometry, as developed in Euclid’s Elements, and practical geometry, we will establish a relation between geometric objects and figures. Geometric objects are (...)

  23. The hysterical anorexia epidemic in the French nineteenth-century.Sara Valente - 2016 - Dialogues in Philosophy, Mental and Neuro Sciences 9 (1):22-23.
    The official birth of hysterical anorexia is attributed to the French alienist Ernest Charles Lasègue (1816-1883). Starting from his 1873 article, anorexia as a ‘new’ psychopathological picture is subjected to extensive clinical and theoreticalstudy. This paper is not an analysis about the process through which anorexia was formalized as specific psychiatric condition. Rather, it focuses on another important issue: the possibility that the ‘same’ disorder may have different meaning depending on the historical period considered. Furthermore, it is asserted that the (...)

  24. Philosophy of Physics.Mario Bacelar Valente - 2012 - History and Philosophy of Science and Technology - EOLSS.
    Philosophy of Physics has emerged recently as a scholarly important subfield of philosophy of science. However outside the small community of experts it is not a well-known field. It is not clear even to experts the exact nature of the field: how much philosophical is it? What is its relation to physics? In this work it is presented an overview of philosophy of physics that tries to answer these and other questions.

  26. On the representational role of Euclidean diagrams: representing qua samples.Tamires Dal Magro & Matheus Valente - 2021 - Synthese 199 (1-2):3739-3760.
    We advance a theory of the representational role of Euclidean diagrams according to which they are samples of co-exact features. We contrast our theory with two other conceptions, the instantial conception and Macbeth’s iconic view, with respect to how well they accommodate three fundamental constraints on theories of the Euclidean diagrammatic practice— that Euclidean diagrams are used in proofs whose results are wholly general, that Euclidean diagrams indicate the co-exact features that the geometer is allowed to infer from them and (...)

    If emotion is not an arbitrary compilation of fixed types of (descriptive, conceptual, conative, prescriptive) content, nor a state that can be reduced to other types of pre-existing (perceptual, cognitive, behavioral) states, then what sort of thing is it really? Tom Cochrane has proposed that emotions are valent representations of situated concerns. Valent representation is a type of mental content whose function is to detect the presence or absence of certain conditions; what makes that type of content valent is that (...)

    Functional intentionality is the dominant theory about how mental states come to have the content that they do. Phenomenal intentionality is an increasingly popular alternative to that orthodoxy, claiming that intentionality cannot be functionalized and that nothing is a mental state with intentional content unless it is phenomenally conscious. There is a consensus among defenders of phenomenal intentionality that the kind of phenomenology that is both necessary and sufficient for having a belief that "there is a tree in the quad" (...)

    It is argued that colour name strategy, object name strategy, and chunking strategy in memory are all aspects of the same general phenomena, called stereotyping, and this in turn is an example of a know-how representation. Such representations are argued to have their origin in a principle called the minimum duplication of resources. For most the subsequent discussions existence of colour name strategy suffices. It is pointed out that the BerlinA- KayA universal partial ordering of colours and the frequency of (...)
