Why do we remember the past and not the future? What does it mean for time to "flow"? Do we exist in time or does time exist in us? In lyric, accessible prose, Carlo Rovelli invites us to consider questions about the nature of time that continue to puzzle physicists and philosophers alike. For most readers this is unfamiliar terrain. We all experience time, but the more scientists learn about it, the more mysterious it remains. We think of it (...) as uniform and universal, moving steadily from past to future, measured by clocks. Rovelli tears down these assumptions one by one, revealing a strange universe where at the most fundamental level time disappears. He explains how the theory of quantum gravity attempts to understand and give meaning to the resulting extreme landscape of this timeless world. Weaving together ideas from philosophy, science and literature, he suggests that our perception of the flow of time depends on our perspective, better understood starting from the structure of our brain and emotions than from the physical universe.

This article argues for a new interpretation of the realist claim that politics is autonomous from morality and involves specific political values. First, this article defends an original normative source: functional normativity. Second, it advocates a substantive functional standard: political institutions ought to be assessed by their capacity to select and implement collective decisions. Drawing from the ‘etiological account’ in philosophy of biology, I will argue that functions yield normative standards, which are independent from morality. For example, a ‘good heart’ (...) is one that pumps blood well, and a good army is one that it is effective at exerting military force. I then interpret realism’s naturalistic conception of politics as an etiological function of social groups: namely making binding collective decisions under persistent disagreement. I conclude that political institutions should be evaluated realistically by how well they perform this task. Finally, I assess trade-offs between this functional political normativity and other moral values. I conclude that justice, fairness, freedom and equality remain obviously important concerns, but only once the basic political function is secured. (shrink)

Facts happen at every interaction, but they are not absolute: they are relative to the systems involved in the interaction. Stable facts are those whose relativity can effectively be ignored. In this work, we describe how stable facts emerge in a world of relative facts and discuss their respective roles in connecting quantum theory and the world. The distinction between relative and stable facts resolves the difficulties pointed out by the no-go theorem of Frauchiger and Renner, and is consistent with (...) the experimental violation of the Local Friendliness inequalities of Bong et al.. Basing the ontology of the theory on relative facts clarifies the role of decoherence in bringing about the classical world and solves the apparent incompatibility between the ‘linear evolution’ and ‘projection’ postulates.

This volume examines the limitations of mathematical logic and proposes a new approach to logic intended to overcome them. To this end, the book compares mathematical logic with earlier views of logic, both in the ancient and in the modern age, including those of Plato, Aristotle, Bacon, Descartes, Leibniz, and Kant. From the comparison it is apparent that a basic limitation of mathematical logic is that it narrows down the scope of logic confining it to the study of deduction, without (...) providing tools for discovering anything new. As a result, mathematical logic has had little impact on scientific practice. Therefore, this volume proposes a view of logic according to which logic is intended, first of all, to provide rules of discovery, that is, non-deductive rules for finding hypotheses to solve problems. This is essential if logic is to play any relevant role in mathematics, science and even philosophy. To comply with this view of logic, this volume formulates several rules of discovery, such as induction, analogy, generalization, specialization, metaphor, metonymy, definition, and diagrams. A logic based on such rules is basically a logic of discovery, and involves a new view of the relation of logic to evolution, language, reason, method and knowledge, particularly mathematical knowledge. It also involves a new view of the relation of philosophy to knowledge. This book puts forward such new views, trying to open again many doors that the founding fathers of mathematical logic had closed historically. (shrink)

The fragment 140 a S.-M. = G 8 Ruth. is likely to deal with two different feats of Herakles. The lines b 21–b 33 seem to concern Cycnus, an impious hero killed by Herakles by order of Apollo. The rest of the fragment seems to concern the beginning of Herakles’ expedition against Laomedon. I think Pindarus presupposes a legend according to which Herakles spent the most part of his life in Thebes; such an interpretation might explain both the obscure expression (...) πέραν ἰσϑμὸν διαβαίς and other details. The opinion the fragment belonged to the Paianes is in my view right. (shrink)

This article argues that political realists have at least two strategies to provide distinctively political normative judgements that have nothing to do with morality. The first ground is instrumental normativity, which states that if we believe that something is a necessary means to a goal we have, we have a reason to do it. In politics, certain means are required by any ends we may intend to pursue. The second ground is epistemic normativity, stating that if something is true, this (...) gives us a reason to believe it. In politics, there are certain empirical regularities that ought to be acknowledged for what they are. Both sources are flawed. Instrumental normativity only requires coherence between attitudes and beliefs, and one can hang on to false beliefs to preserve attitudes incompatible with reality. I may desire to eschew power relations, and accordingly I may imagine politics to be like a camping trip. Epistemic normativity, on the other hand, operates critically, striking down existing normative claims. It shows us that politics is nothing like a camping trip, but it doesn’t tell us what we should do about it. We conclude by showing that if the two are taken together, they remedy each other’s flaws.

This is a contribution to a book on quantum gravity and philosophy. I discuss nature and origin of the problem of quantum gravity. I examine the knowledge that may guide us in addressing this problem, and the reliability of such knowledge. In particular, I discuss the subtle modification of the notions of space and time engendered by general relativity, and how these might merge into quantum theory. I also present some reflections on methodological questions, and on some general issues in (...) philosophy of science which are are raised by, or a relevant for, the research on quantum gravity.

The aim of this paper is to show that the Plautine Textgeschichte as reconstructed by M. Deufert may be regarded as convincing, although some aspects need to be corrected. A new examination of Gellius 3. 3, there is no reason to think that he devoted his editorial activity to Plautus. In the last part of the paper we discuss the famous problem of the identity of Sisenna. Although some recent scholars have tried to demonstrate that the Sisenna, who composed a (...) Plautine commentary, was the famous historian, I prefer to maintain Deufert’s opinion, viz. that Sisenna the commentator of Plautus lived in the second or third century AD. A new analysis of some of Sisenna’s grammatical fragments is also provided. (shrink)

Ethical veganism is the view that raising animals for food is an immoral practice that must be stopped because of the harm it causes to the animals, the environment, and our health. Carlo Alvaro argues the only way to stop that harm is to acquire the virtues that enable us to act justly and benevolently toward animals.

Quantum mechanics is not about 'quantum states': it is about values of physical variables. I give a short fresh presentation and update on the *relational* perspective on the theory, and a comment on its philosophical implications.

Substructural logics and their application to logical and semantic paradoxes have been extensively studied. In the paper, we study theories of naïve consequence and truth based on a non-reflexive logic. We start by investigating the semantics and the proof-theory of a system based on schematic rules for object-linguistic consequence. We then develop a fully compositional theory of truth and consequence in our non-reflexive framework.

Background: For many years the body of literature known as ‘care ethics’ or ‘ethics of care’ has been discussed as regards its status and nature. There is much confusion and little structured discussion. The paper of Klaver et al. (2014) was written as a discussion article to which we respond. Objectives: We aim to contribute to the ongoing discussion about the status and nature of care ethics. Research design: Responding to ‘Demarcation of the ethics of care as a discipline’ by (...) Klaver et al. (2014) and ‘Three versions of an ethics of care’ by Edwards (2009), we identified shared concerns and formulated criticisms of both texts in order to develop an alternative view. Participants and research context: This paper has been written from the academic context of a master in care ethics an policy. Ethical considerations: We have tried to be fair and respectful to the authors discussed. Findings: Both Klaver et al. (2014) and Edwards (2009) raise important concerns about the question if care ethics can be considered an academic discipline, and to what extend it can be seen as a moral theory. Despite shared concerns, their arguments fail to convince us in all respects. Discussion and conclusion: We propose to conceive care ethics as an interdisciplinary field of inquiry, incorporating a dialectical relation between empirical research and theoretical reflection. Departing from the notion of caring as a practice of contributing to a life-sustaining web, we argue that care ethics can only profit from a loosely organized academic profile that allows for flexibility and critical attitude that brings us close to the good emerging in specific practices. This asks for ways of searching for a common focus and interest that is inherently democratic and dialogical and thus beyond demarcation. (shrink)

In this groundbreaking work, Carlo Sini, one of Italy's leading contemporary philosophers, brings American pragmatism to the Milan school of phenomenology.

Truth-theoretic deflationism holds that truth is simple, and yet that it can fulfil many useful logico-linguistic roles. Deflationism focuses on axioms for truth: there is no reduction of the notion of truth to more fundamental ones such as sets or higher-order quantifiers. In this paper I argue that the fundamental properties of reasonable, primitive truth predicates are at odds with the core tenets of classical truth-theoretic deflationism that I call fix, express, and quantify. Truth may be regarded as a broadly (...) logical, sui generis notion. However, this has little to do with the original aims of the deflationary theory of truth. (shrink)

We discuss the principles for a primitive, object-linguistic notion of consequence proposed by ) that yield a version of Curry’s paradox. We propose and study several strategies to weaken these principles and overcome paradox: all these strategies are based on the intuition that the object-linguistic consequence predicate internalizes whichever meta-linguistic notion of consequence we accept in the first place. To these solutions will correspond different conceptions of consequence. In one possible reading of these principles, they give rise to a notion (...) of logical consequence: we study the corresponding theory of validity by showing that it is conservative over a wide range of base theories: this result is achieved via a well-behaved form of local reduction. The theory of logical consequence is based on a restriction of the introduction rule for the consequence predicate. To unrestrictedly maintain this principle, we develop a conception of object-linguistic consequence, which we call grounded consequence, that displays a restriction of the structural rule of reflexivity. This construction is obtained by generalizing Saul Kripke’s inductive theory of truth. Grounded validity will be shown to satisfy several desirable principles for a naïve, self-applicable notion of consequence. (shrink)

Shannon's notion of relative information between two physical systems can function as foundation for statistical mechanics and quantum mechanics, without referring to subjectivism or idealism. It can also represent a key missing element in the foundation of the naturalistic picture of the world, providing the conceptual tool for dealing with its apparent limitations. I comment on the relation between these ideas and Democritus.

The moral and political philosophy of Wilhelm Röpke is among the finest instances of European classical liberalism in the twentieth century, and in many occasions he stated that only a society which understands the importance of markets can be reconciled with human dignity. Röpke elaborated a political theory that focused on the harmony between moral principles and economic law. In this sense, his liberalism is unique not only because it defends private property and competition as pillars of a thriving economy, (...) but above all that it provides the preconditions of a society that can remain secure from the immorality of despotism and subsequent ethical degeneration. To that end he upheld an economic order based on voluntary cooperation as the basis for a more humane society, emphasizing the role of institutional competition and federalism. Röpke’s cultural conservatism should not therefore be misunderstood, as it is very much connected with his defense of the essential role of property. It is only in this sense that he found in liberal humanism a third way, which is not however situated halfway between the market and socialism, but which represents instead a defense of a competitive society that is aware of its own historical and cultural basis.

La presente investigación busca generar un diálogo entre la filosofía de las ciencias de Susan Haack y la teoría queer de Judith Butler. Para ello, recorreremos primero los hitos más importantes del feminismo y, en un segundo momento, veremos cómo estos desembocaron en la teoría queer.

Como sección conclusiva, pondremos ambas (...) posturas en diálogo considerando sus planteamientos en un caso concreto: la intersexualidad. (shrink)

We study the relationships between two clusters of axiomatizations of Kripke’s fixed-point models for languages containing a self-applicable truth predicate. The first cluster is represented by what we will call ‘\-like’ theories, originating in recent work by Halbach and Horsten, whose axioms and rules are all valid in fixed-point models; the second by ‘\-like’ theories first introduced by Solomon Feferman, that lose this property but reflect the classicality of the metatheory in which Kripke’s construction is carried out. We show that (...) to any natural system in one cluster—corresponding to natural variations on induction schemata—there is a corresponding system in the other proving the same sentences true, addressing a problem left open by Halbach and Horsten and accomplishing a suitably modified version of the project sketched by Reinhardt aiming at an instrumental reading of classical theories of self-applicable truth.

There are fields of research on NE which still need attention: the edition of the text the style and rhetorical and logical instruments employed by Aristotle in setting out his position. After indicating the situation of the research on the text of NE, I describe some rhetorical devices used by Aristotle in his work: the presence of a preamble, clues about how the argument will be developed, a tendency to introduce new arguments in an inconspicuous way and the articulation of (...) general definitions through more specific analyses. At a deeper level NE seems to be organised on the model of investigating definitions described in the second Book of the Postenor Analytics, and not according the so-called' dialectical method'. In conclusion I argue that NE is not an early or a confused work, as some scholars maintain, but rather a skilful construction, the fruit of a mature intelligence. (shrink)

The terms of a mathematical problem become precise and concise if they are expressed in an appropriate notation, therefore notations are useful to mathematics. But are notations only useful, or also essential? According to prevailing view, they are not essential. Contrary to this view, this paper argues that notations are essential to mathematics, because they may play a crucial role in mathematical discovery. Specifically, since notations may consist of symbolic notations, diagrammatic notations, or a mix of symbolic and diagrammatic notations, (...) notations may play a crucial role in mathematical discovery in different ways. Some examples are given to illustrate these ways. (shrink)

In this paper I analyze four so-called “principles of expertise”; that is, good epistemic practices that are normatively motivated by the epistemological literature on expert judgment. I highlight some of the problems that the four principles of expertise run into, when we try to implement them in concrete contexts of application (e.g. in science committees). I suggest some possible alternatives and adjustments to the principles, arguing in general that the epistemology of expertise should be informed both by case studies and (...) by the literature on the use of experts in science practice.

The article examines the development of Husserl’s early philosophy from his Habilitationsschrift to the Philosophie der Arithmetik . An attempt will be made at reconstructing the lost Habilitationsschrift . The examined sources show that the original version of the Habilitationsschrift was by far broader than the printed version, and included most topics of the PA. The article contains an extensive and detailed comparison of these texts to illustrate the changes in Husserl’s position before and after February 1890. This date is (...) taken as a turning point in his development, because of Husserl’s announcement in a letter to Carl Stumpf that he was mistaken in his basic assumption, i.e. that the analysis of the concept of Anzahl would yield a foundation for arithmetic. Some interesting conclusions in this respect can also be drawn from an unpublished lecture that Husserl held in the WS 1889/90, in which he anticipates aspects of his position hitherto deemed to belong to the last phases of the PA.

The view that the subject matter of epistemology is the concept of knowledge is faced with the problem that all attempts so far to define that concept are subject to counterexamples. As an alternative, this article argues that the subject matter of epistemology is knowledge itself rather than the concept of knowledge. Moreover, knowledge is not merely a state of mind but rather a certain kind of response to the environment that is essential for survival. In this perspective, the article (...) outlines an answer to four basic questions about knowledge: What is the role of knowledge in human life? What is the relation between knowledge and reality? How is knowledge acquired? Is there any a priori knowledge? (shrink)

In "Wittgenstein in relation to his times" Von Wright1 poses a dilemma regarding the relationship between three wittgensteinian tenets: (i) the view that individual's beliefs and thoughts are entrenched in accepted language games and socially sanctioned forms of life (ii) the view that "philosophical problems are disquietudes of the mind caused by some malfunctioning in the language games, and hence in the way of life of the community". (iii) the "rejection of the scientific-technological civilisation of industrialised societies". The dilemma is (...) the following: is Wittgenstein's rejection of technological civilisation strictly linked to his general view of philosophy? Or is it "only contingently - that is for historical and psychological reasons, connected with the other two in Wittgenstein's thought"? Von Wright argues, even with some doubts, for a strong link between Wittgenstein's rejection of technological society and his general approach to philosophy; the argument is as follows: "because of the interlocking of language and ways of life, a disorder in the former reflects disorder in the latter. If philosophical problems are symptomatic of language, producing malignant outgrowths which obscure our thinking, then there must be a cancer in the Lebensweise, in the way of life itself" (p.119). The argument seems to be not compelling; among some of the main philosophical problems Wittgenstein is willing to "cure" there are misunderstandings lying in the history of our language much time before our technological civilisation (Wittgenstein refers to Augustine and Plato as suffering these disorder of language). We should generalise the criticism to technological society to the effect of enclosing ancient Greece. In this way the criticism seems to loose all its polemical vein, becoming a generic criticism of the structures of western thought since Greece. But probably this was the point Wittgenstein wanted to make in his criticism of the idea of progress and technological civilisation. I will argue therefore for the second horn of the dilemma, relying on another kind of de facto argument: contemporary technological civilisation is embodying some of Wittgenstein's main ideas (we might also note that these ideas are among the strongest points Wittgenstein gives against Greek classical tradition in philosophy)..

This paper tries to give some substance to local holism, a picture that seems to fit Wittgenstein’s analysis of the working of language. In the first part I state the well-known paradox of semantic holism, as discussed in philosophy of language: if meaning is holistic there is no possibility to share any meaning. In the second part I present the different answers to this paradox, from atomism to different forms of holism. In the third part I give a criticism of (...) the traditional interpretation of Wittgenstein as a supporter of global holism. As an alternative lecture I will suggest some lines of Wittgenstein's thought leading towards a definition of local holism. Eventually I will show connections with ideas developed in Multi Context theories in artificial intelligence, which help to show a possible direction of inquiry about restrictions on locality.

The so-called “intentional object” occupies a central position in the debates about intentionality in Brentano and the Brentano School. How does it relate to the correlate, the content, or the intended, possibly external, transcendent object? Does it perhaps even coincide with one of these? There was no clear consensus on this neither in Brentano’s time nor today. In order to develop a new perspective on the problem of the intentional object, I would like to introduce a deliberately radical interpretation and (...) related terminological change: what if we were to avoid any talk of “object” in this context altogether? Perhaps this could help avoid the ambiguities and misunderstandings associated with talk of “intentional objects.” In my contribution I would like to sketch such an interpretation and consider whether this attempt could be useful to reframe the debate.
