Frauchiger and Renner have recently claimed to prove that “Single-world interpretations of quantum theory cannot be self-consistent”. This is contradicted by a construction due to Bell, inspired by Bohmian mechanics, which shows that any quantum system can be modelled in such a way that there is only one “world” at any time, but the predictions of quantum theory are reproduced. This Bell–Bohmian theory is applied to the experiment proposed by Frauchiger and Renner, and their argument is critically examined. It is (...) concluded that it is their version of “standard quantum theory”, incorporating state vector collapse upon measurement, that is not self-consistent. (shrink)

According to quantum mechanics, statements about the future made by sentient beings like us are, in general, neither true nor false; they must satisfy a many-valued logic. I propose that the truth value of such a statement should be identified with the probability that the event it describes will occur. After reviewing the history of related ideas in logic, I argue that it gives an understanding of probability which is particularly satisfactory for use in quantum mechanics. I construct a lattice (...) of future-tense propositions, with truth values in the interval [0, 1], and derive logical properties of these truth values given by the usual quantum-mechanical formula for the probability of a history.

It is argued that the conventional formulation of quantum mechanics is inadequate: the usual interpretation of the mathematical formalism in terms of the results of measurements cannot be applied to situations in which discontinuous transitions (''quantum jumps'') are observed as they happen, since nothing that can be called a measurement happens at the moment of observation. Attempts to force such observations into the standard mould lead to absurd results: ''a watched pot never boils''. Experiments show both that this result is (...) correct when the experiment does indeed consist of a series of measurements, and that it is not when the experiment consists of a period of observation: quantum jumps do happen. The possibilities for improving the formulation by incorporating transitions in the basic postulates are reviewed, and a satisfactory postulate is obtained by modifying a suggestion of Bell's. This requires a distinction between the external description of the whole of a physical system and internal descriptions which are themselves physical events in the system. It is shown that this gives correct results for simple unstable systems and for the quantum-jump experiments. (shrink)

The quantum-mechanical description of the world, including human observers, makes substantial use of entanglement. In order to understand this, we need to adopt concepts of truth, probability and time which are unfamiliar in modern scientific thought. There are two kinds of statements about the world: those made from inside the world, and those from outside. The conflict between contradictory statements which both appear to be true can be resolved by recognising that they are made in different perspectives. Probability, in an (...) objective sense, belongs in the internal perspective, and to statements in the future tense. Such statements obey a many-valued logic, in which the truth values are identified as probabilities. (shrink)

I discuss the meaning of probability in the Everett-Wheeler interpretation of quantum mechanics, together with the problem of defining histories. To resolve these, I propose an understanding of probability arising from a form of temporal logic: the probability of a future-tense proposition is identified with its truth value in a many-valued and context-dependent logic. In short, probability is degree of truth. These ideas appear to be new, but they are natural and intuitive, and relate to traditional naive ideas of time (...) and chance. Indeed, I argue that Everettian quantum mechanics is the only form of scientific theory that truly incorporates the perception that the future is open. (shrink)

We examine the possible states of subsystems of a system of bits or qubits. In the classical case (bits), this means the possible marginal distributions of a probability distribution on a finite number of binary variables; we give necessary and sufficient conditions for a set of probability distributions on all proper subsets of the variables to be the marginals of a single distribution on the full set. In the quantum case (qubits), we consider mixed states of subsets of a set (...) of qubits; in the case of three qubits we find quantum Bell inequalities—necessary conditions for a set of two-qubit states to be the reduced states of a mixed state of three qubits. We conjecture that these conditions are also sufficient. (shrink)

A revision of George Kennedy's translation of, introdution to, and commentary on Aristotle's On Rhetoric. His translation is most accurate, his general introduction is the most thorough and insightful, and his brief introductions to sections of the work, along with his explanatory footnotes, are the most useful available.

Recent research on algebraic models of _quasi-Nelson logic_ has brought new attention to a number of classes of algebras which result from enriching (subreducts of) Heyting algebras with a special modal operator, known in the literature as a _nucleus_. Among these various algebraic structures, for which we employ the umbrella term _intuitionistic modal algebras_, some have been studied since at least the 1970s, usually within the framework of topology and sheaf theory. Others may seem more exotic, for their primitive operations (...) arise from algebraic terms of the intuitionistic modal language which have not been previously considered. We shall for instance investigate the variety of _weak implicative semilattices_, whose members are (non-necessarily distributive) meet semilattices endowed with a nucleus and an implication operation which is not a relative pseudo-complement but satisfies the postulates of Celani and Jansana’s strict implication. For each of these new classes of algebras we establish a representation and a topological duality which generalize the known ones for Heyting algebras enriched with a nucleus. (shrink)

Purpose. The article is aimed to substantiate the view on the phenomenon of laughter as a subject of semiotic analysis, which leads to the following tasks: to reveal the possibilities of semiotics application in the study of laughter nature; to analyze the phenomenon of laughter as a cultural and natural phenomenon, as a sign and as an attribute; to consider the place of laughter in culture, which is understood as a sign system. Theoretical basis. The semiotic approach proceeds from the (...) fact that human lives in the world of signs, all the surrounding reality can be interpreted as a sign system. The basic concept of semiotics is the concept of a sign. The theoretical basis of the article is understanding the culture as a sign-symbolic system. Laughter is considered as a phenomenon ontologically rooted in human culture. At the same time, laughter is on the edge of culture. The research is based on the work of semiotic authors, cultural researchers, and the researchers of laughter. Originality. The originality lies in the application of the semiotic method to the research of laughter phenomenon, consideration of the dialectics of natural and cultural, signedness and non-signedness, manifested in the phenomenon of laughter. Conclusions. Laughter is considered as a psychophysiological phenomenon and as a cultural phenomenon. Laughter acts as an emotional manifestation, a physiological reaction, but socially and culturally mediated. In any case, laughter indicates an emotional or cognitive state of a human. Laughter acts as a process and result of the interpretation of a sign, a reaction to a sign. Laughter is a form and a means of communication. Being a natural phenomenon, in the process of social evolution, laughter acquires signedness, is integrated by culture as a sign system, and, at the same time, maintains a connection with nature. Thus, laughter occupies an ambivalent position between nature and culture. In the phenomenon of laughter, the dual state of human is revealed. In laughter, boundaries are blurred, the unity and opposition of natural and cultural, biological and social, soul and body, thought and feeling, sign and attribute are manifested. (shrink)

Eco-labels emphasize information disclosure as a tool to induce environmentally friendly behaviors by both firms and consumers. The goal of eco-labels is to reduce information asymmetry between producers and consumers over the environmental attributes of a product or service. However, by focusing on this information asymmetry, rather than on how the label meets consumer needs, eco-labels may send irrelevant, confusing, or even detrimental messages to consumers. In this article, the authors investigate how the environmental signal of eco-labels interacts with product (...) characteristics such as brand, quality, and price. In a discrete choice experiment, the authors examine consumer response to two similar eco-labels for wine, one associated with a quality reduction and the other not. The results show that respondents preferred both eco-labeled wines over otherwise identical conventional counterparts when the price was lower and the wine was from a lower quality region. However, they preferred conventional, more expensive wine from a high-quality region. This preference indicates that respondents not only obtain some warm glow value from eco-labeled wine but also possibly interpret eco-labeling as a signal of lower quality. This relationship held across both types of eco-labels, meaning that consumers did not understand the difference between them. This research contributes to the literature on information disclosure policies by highlighting important elements for effective eco-labels. These elements include consumer awareness and understanding of the eco-label, and consumer willingness to pay for an eco-labeled product. The results emphasize the need to create eco-labels that communicate clearly both the environmental attributes and the private benefits associated with them. (shrink)

We are immersed within an odorous sea of chemical currents that we parse into individual odors with complex structures. Odors have been posited as determined by the structural relation between the molecules that compose the chemical compounds and their interactions with the receptor site. But, naturally occurring smells are parsed from gaseous odor plumes. To give a comprehensive account of the nature of odors the chemosciences must account for these large distributed entities as well. We offer a focused review of (...) what is known about the perception of odor plumes for olfactory navigation and tracking, which we then connect to what is known about the role odorants play as properties of the plume in determining odor identity with respect to odor quality. We end by motivating our central claim that more research needs to be conducted on the role that odorants play within the odor plume in determining odor identity. (shrink)

Purpose. To consider the uniqueness of Descartes’ way of interpreting poetry as a type of philosophizing that makes it possible to comprehend the metaphysical nature of man. Its implementation involves the consistent solution of the following tasks: a) understanding methodological changes in the philosophy of the 20th century in the process of actualization of anthropological interest; b) argumentation of the importance of poetic thinking for early Descartes in the process of addressing modern historians of philosophy and the thinker’s texts. Theoretical (...) basis. I rely on the conceptual positions of phenomenology, existentialism and hermeneutics. Originality. Finding of the study is that poetic thinking is the most authentic way of meaningful comprehension of the metaphysicity of man. The paper outlines the nature of the expression of this correlation in the philosophizing of the 20th-21th centuries and substantiates the thesis about the importance of the poetic principle for understanding the phenomenon of man in early works by Descartes. Conclusions. The paper examined the methodological shifts in anthropologically oriented philosophizing of the 20th-21th centuries and focused on the manifestations of related moments in the philosophical legacy of Descartes. The latter demonstrates the existence of a still underestimated version of interpreting the metaphysical foundations of human existence, the form of understanding of which is poetic thinking. It is a form of caring for the humane in man. (shrink)

The natural instinct for members of the Committee on Publication Ethics, which now number almost 12,200, as well as academia, is to assume that this organization works under strict and clearly defined ethical parameters, with a solid vision, and an independent mandate that is not influenced by power, think tanks, or partisan interests. Naturally, whistle-blowing and science shaming are not practices that one would usually associate with an ethics organization like COPE, because they involve ethically and morally questionable practices. Despite (...) this, ethical borders have become blurred between the objectives of Retraction Watch and PubPeer, two self-moderated science watchdogs that rely heavily on these questionable practices, in their efforts to grow and survive, and the values espoused by COPE. A Retraction Watch post, in which the former COPE Chair, Virginia Barbour, made a claim of apparent harassment, is the most striking example of the dangers when collaboration may take place between science-shaming websites, and an ethics organization, COPE. These bonds appear to have been in development for a number of years already, with the inclusion of Elizabeth Wager, the former COPE Chair, as a director of The Center for Science Integrity Inc., Retraction Watch’s parent organization. Retraction Watch was financed by, among other groups, the Laura and John Arnold Foundation, whose leader, John Arnold, an ex-Enron trader, declared a “war on bad science”, which may naturally include the destruction of aspects of science as well. Retraction Watch embraces several infamous pseudonymous personas under the broad umbrella of freedom of speech, liaising thereby with PubPeer. There is no doubt that errors in the literature need correcting, but this apparent connection with COPE raises questions about the basic ethical foundation of this relationship. Are scientists to embrace this bond between COPE and science watchdogs and pseudonymous whistle-blowers as the new normal in the correction of the scientific literature? This opinion piece puts forward arguments why the author believes that the ethical compass of COPE has become skewed. (shrink)

The paper builds on the postulate of “myths we live by,” which shape our imaginative life (and hence our social expectations), but which are also open to reflective study and reinvention. It applies this principle, in particular, to the concepts of love and vulnerability. We are accustomed to think of the condition of vulnerability in an objectifying and distancing way, as something that affects the bearers of specific (disadvantaged) social identities. Against this picture, which can serve as a pretext for (...) paternalist and controlling attitudes to the groups in question – notably to women – Anderson urges us to reimagine our vulnerability as a condition not merely of exposure to violence but of openness to mutual affection, love, and friendship. Hegel’s celebrated image of the owl of Minerva, which takes wing only with the coming of dusk, suggests an association of (philosophical) wisdom with negativity – with the experience of death or loss. Anderson, by contrast, proposes an alternative and more hopeful image of the dawn of enlightenment, in the guise of new ethical dispositions shaped by an emancipatory (and so, no longer an oppressive or sexist) conception of our capacity for love. Her main interlocutors or influences in this piece are Judith Butler (who contributes the idea of a “relational ontology”), Michèle Le Doeuff, and Mary Midgley. (shrink)

As its subtitle indicates, Democracy’s Discontent is a study of the political philosophies that have guided America’s public life. The “search” Michael Sandel describes has, in his view, temporarily come to a disappointing resolution in America’s acceptance of a liberal “public philosophy” that “cannot secure the liberty it promises” and has left Americans “discontented” with their “loss of self-government and the erosion of community”. This theme is unlikely to surprise readers familiar with Sandel’s earlier work. What may surprise them is (...) how little of Sandel’s second book is devoted to his critique of liberal theory or to his defense of his favored “republican” alternative. Far less than 10 percent of the book is devoted to characterizing liberal and republican political philosophy and to argument concerning their relative theoretical virtues. The body of Democracy’s Discontent is a history of American Constitutional law and political/economic debate, from pre-Revolutionary times to the Clinton presidency, all designed to show that the republican vision that has animated so much of that history has been recently abandoned to our detriment, replaced by a liberal public philosophy whose dramatic failure in practice “recapitulates” its “poverty in theory”. Sandel’s history is lively and engaging, and many of his analyses are insightful and persuasive. But the looseness in his treatment of theory regularly infects the conclusions he draws from this history and undermines his efforts to show that American political practice indicts liberal political philosophy.

David Chalmers appears to assume that we can meaningfully discuss what goes on in human heads without paying any attention to the words in which we couch our statements. This paper challenges this assumption and argues that the initial problem is that of metalanguage: if we want to say something clear and valid about us humans, we must think about ourselves outside conceptual English created by one particular history and culture and try to think from a global, panhuman point of (...) view. This means that instead of relying on untranslatable English words such as 'consciousness' and 'experience' we must try to rely on panhuman concepts expressed in cross-translatable words such as THINK, KNOW, and FEEL (Wierzbicka, 2018). The paper argues that after 'a hundred years of consciousness studies' it is time to try to say something about us (humans), about how we think and how we differ from cats and bats, in words that are clear, stable, and human rather than parochially English.
