This position paper advocates combining formal epistemology and the new paradigm psychology of reasoning in the studies of conditionals and reasoning with uncertainty. The new paradigm psychology of reasoning is characterized by the use of probability theory as a rationality framework instead of classical logic, used by more traditional approaches to the psychology of reasoning. This paper presents a new interdisciplinary research program which involves both formal and experimental work. To illustrate the program, the paper discusses recent work on the (...) paradoxes of the material conditional, nonmonotonic reasoning, and Adams’ Thesis. It also identifies the issue of updating on conditionals as an area which seems to call for a combined formal and empirical approach. (shrink)

The place of evidence regarding joint commitment and plural action is mostly reserved for documents and explicit linguistic expressions. This paper considers the problem of evidence in cases of engaged (jointly committed) social acts where there is no explicit expression or binding document, yet can still be ascribed to a plural subject. The argument rests on the double meaning of the term factum as fact (factum brutum) and deed (factum practica), as well as contemporary debates about the topic of fact (...) of reason in Kant. The text seeks to show that in certain cases, the execution of an act or the obligation produced by it can be considered evidence of a plural subject. Thus, these facts deserve a special position in relation to scientific evidence. (shrink)

The article focuses on the crucial changes that science as an established social institution and an epistemological enterprise is undergoing, the key one is the loss of its monopoly on the production of socially useful knowledge and gradual transformation into something new, which, due to institutional and cultural reasons, we continue to call ‘science’. We suppose that the most appropriate conceptualization of the new phenomenon, which is replacing science as an institution, is “technoscience”, since the technical component in scientific practices (...) has now taken a dominant position and technology production has become more important than fundamental knowledge. Technoscience has at least two sources: 1) capitalization of scientific activity that has led to classical science has been replaced with technoscience developing on first-priority funded applied research; 2) theorization and autonomy of the techno sphere, which have resulted in instrumentalization of all levels of knowledge production as well as in technological / symbolic construction of reality and tangled ontology of technoscientific objects. We discuss both of these sources, with particular attention being paid to such trends as epistemic strategies transformation, modified reality, social sciences and humanities conformation to technoscience norms, and knowledge bearers egalitarianization. A crucial transformation of both science itself and its position in society breaks inevitably a demarcation line that separates scientific knowledge from other types of knowledge while promotes the replacement of scientific theory with discourses. Apparently, in “technoscience” an ethos of its own is being formed, where interaction with the “external environment” (with other social spheres) is crucial. In this context, scientific activity is becoming more and more transepistemic, transinstitutional practice, and accordingly ceases to be guided by the classical scientific ethos determined by the goals and objectives of academic community itself.

Throughout the history of mankind, energy security has been always seen as a means of protection from disruptions of essential energy systems. The idea of protection from disorders emerged from the process of securing political and military control over energy resources to set up policies and measures on managing risks that affect all elements of energy systems. The various systems placed in a place to achieve energy security are the driving force towards the energy innovations or emerging trends in the (...) energy sector. Our paper discusses energy security status and innovations in the energy sector in European Union (EU). We analyze the recent up-to-date developments of the energy policy and exploitation of energy sources, as well as scrutinize the channels of energy streaming to the EU countries and the risks associated with this energy import. Moreover, we argue that the shift to the low-carbon production of energy and the massive deployment of renewable energy sources (RES) might become the key issue in ensuring the energy security and independency of the EU from its external energy supplies. Both RES, distributed energy resources (DER) and “green energy” that will be based on the energy efficiency and the shift to the alternative energy supply might change the energy security status quo for the EU.

The main purpose of the study is to determine the key aspects of the mechanisms of state management of the exchange of information about cyberattacks, cyber incidents, and information security incidents. The methodology includes a set of theoretical methods. Modern government, on the one hand, must take into account the emergence of such a new weapon as cyber, which can break various information systems, can be used in hybrid wars, influence political events, pose a threat to the national security of (...) any state. As a result of the study, key elements of the mechanisms of state management of the exchange of information about cyberattacks, cyber incidents, and information security incidents were identified.

This volume of the Logica Yearbook series brings together articles presented at the annual international symposium Logica 2019, Hejnice, the Czech Republic. The articles range over mathematical and philosophical logic, history and philosophy of logic, and the analysis of natural language.

The conceptual spaces approach has recently emerged as a novel account of concepts. Its guiding idea is that concepts can be represented geometrically, by means of metrical spaces. While it is generally recognized that many of our concepts are vague, the question of how to model vagueness in the conceptual spaces approach has not been addressed so far, even though the answer is far from straightforward. The present paper aims to fill this lacuna.

Conditionals are sentences of the form 'If A, then B', and they play a central role in scientific, logical, and everyday reasoning. They have been in the philosophical limelight for centuries, and more recently, they have been receiving attention from psychologists, linguists, and computer scientists. In spite of this, many key questions concerning conditionals remain unanswered. While most of the work on conditionals has addressed semantical questions - questions about the truth conditions of conditionals - this book focuses on the (...) main epistemological questions that conditionals give rise to, such as: what are the probabilities of conditionals? When is a conditional acceptable or assertable? What do we learn when we receive new conditional information? In answering these questions, this book combines the formal tools of logic and probability theory with the experimental approach of cognitive psychology. It will be of interest to students and researchers in logic, epistemology, and psychology of reasoning. (shrink)

In this short paper, we investigate the problems with the employment of the notion of freedom and voluntariness in libertarianism. We pretend to demonstrate that these two, as conceived of by libertarians, figure in as the main issue when it comes to justifying its major institutions, say: bequeathing, gifts, transactions (or what they label as “voluntary transfer”). The difficulty here boils down to the fact that a purely rights-based idea of freedom and voluntariness, the pretentions of Nozick notwithstanding, cannot do (...) alone, since it is the consideration whether we do something (e.g. bequeath, donate etc.) voluntarily (or freely) (in a non-moralized sense) that could account for the rights redistribution. Therefore, it seems that – at least sometimes – the notion of voluntariness (or freedom) is prior to the notion of rights. (shrink)

As cognitive enhancement research advances, important ethical questions regarding individual autonomy and freedom are raised. Advocates of cognitive enhancement frequently adopt a procedural approach to autonomy, arguing that enhancers improve an individual’s reasoning capabilities, which are quintessential to being an autonomous agent. On the other hand, critics adopt a more nuanced approach by considering matters of authenticity and self-identity, which go beyond the mere assessment of one’s reasoning capacities. Both positions, nevertheless, require further philosophical scrutiny. In this paper, we investigate (...) the ethics of cognitive enhancement through the lenses of political and philosophical arguments about autonomy and freedom. In so doing, we contend that a substantive, relational account of individual autonomy offers a more holistic understanding of the ethical concerns of cognitive enhancement. (shrink)

The First World War exerted a great influence on the course of twentieth-century history and transformed people’s perception of the world. The collapse of empires and the shipwreck of illusions found their reflection in various spheres of culture and art, including music. Scholars are familiar with how the trauma of war was reflected in the history of the works, lives, and collaboration of two outstanding composers of the twentieth century, Igor Stravinsky and Maurice Ravel. In this article, we explore (...) how, from different perspectives, these composers expressed in music their perception of the war trauma as part of the wider common cultural and social tragedy known as “the collapse of empires”. At the center of our discussion is musical text as a reflection of social phenomena, and how these two composers presented the upheavals that took place in society and their spiritual reaction to them with the help of their musical expressivity. The article focuses on war themes and their reflection in the music of the first half of the twentieth century. (shrink)

Conceptual spaces have become an increasingly popular modeling tool in cognitive psychology. The core idea of the conceptual spaces approach is that concepts can be represented as regions in similarity spaces. While it is generally acknowledged that not every region in such a space represents a natural concept, it is still an open question what distinguishes those regions that represent natural concepts from those that do not. The central claim of this paper is that natural concepts are represented by the (...) cells of an optimally designed similarity space. (shrink)

A number of philosophers and legal scholars have pointed out a fact about punishment that had not been sufficiently appreciated by many traditional accounts, utilitarian, retributive, or ‘mixed’: that evil inflicted on the person punished is not an evil simpliciter , but rather the expression of an important social message—that punishment is a kind of language. The message which it is seen to communicate can broadly be described as condemnation by society of the crime committed. In what is still the (...) only attempt at a general and critical discussion— Anthony Skillen's ‘How to say Things with Walls’—this way of understanding punishment is termed ‘expressionism’. In this paper I propose to sort out the main varieties of expressionism in the philosophy of punishment, and to discuss some of their pros and cons. (shrink)

There has been a growing debate about the ethics of management buy-outs (MBOs). One possible criticism of the MBO is that it serves the interests of incumbent management at the expense of shareholders. In this paper we develop the general arguments concerning the ethical aspects of the MBO to include other forms of buy-out beyond going privates and apply the analysis to MBOs as a mode of privatisation in Central and Eastern Europe (CEE). MBOs are justified in this context postperestroika (...) as a means of incentivising economic activity by giving managers an ownership stake in former state enterprises. The actual mode of privatisation, though, raises issues of social justice and the criticism that MBOs are at the expense of the broader social good. The ethical problem for the CEE is to balance the economic gains of a move to markets with the ethical risks to the agents of these markets. (shrink)

This paper argues that pragmatic considerations similar to the ones that Grice has shown pertain to assertability pertain to acceptability. It further shows how this should affect some widely held epistemic principles. The idea of a pragmatics of belief is defended against some seemingly obvious objections.

This paper aims to contribute to our understanding of the notion of coherence by explicating in probabilistic terms, step by step, what seem to be our most basic intuitions about that notion, to wit, that coherence is a matter of hanging or fitting together, and that coherence is a matter of degree. A qualitative theory of coherence will serve as a stepping stone to formulate a set of quantitative measures of coherence, each of which seems to capture well the aforementioned (...) intuitions. Subsequently it will be argued that one of those measures does better than the others in light of some more specific intuitions about coherence. This measure will be defended against two seemingly obvious objections. (shrink)

We give a negative solution to the problem, posed by A. Chagrov and M. Zakharyaschev, of whether every quasi-normal propositional modal logic can be axiomatized by an independent set of axioms, with the inference rules of Substitution and Modus Ponens.

This paper is concerned with formal solutions to the lottery paradox on which high probability defeasibly warrants acceptance. It considers some recently proposed solutions of this type and presents an argument showing that these solutions are trivial in that they boil down to the claim that perfect probability is sufficient for rational acceptability. The argument is then generalized, showing that a broad class of similar solutions faces the same problem. An argument against some formal solutions to the lottery paradox The (...) argument generalized Some variations Adding modalities Anticipated objections. (shrink)

The article analyzes the effectiveness of quantum theories of mental experience in relation to two ontological problems - the problem of the existence of consciousness in the material world and the problem of the interaction of consciousness and body. A critical analysis of the quantum theories of consciousness by Penrose-Hameroff, M. Tegmark, G. Stapp, M. Fischer and M.B. Mensky shows that they fail to fully explain how complex physical systems generate mental experience without violating the principle of causal closure of (...) the physical world and the principle of epistemological completeness of physics. Quantum mechanics provides specific processes that are the physical basis of the psyche, but do not explain the phenomenal aspect of subjective reality. Nevertheless, the Heisenberg uncertainty principle gives an understanding of how the interaction of consciousness and body within the scientific picture of the world can be carried out without violating the law of energy conservation. It is shown that the quantum theories of consciousness currently being developed have a predominantly panprotopsychic character, which faces a problem due to the fact that the protomental property of physical systems must be expressed quantitatively and correspond to the value included in the physical equations. As a result, it is concluded that in order to develop quantum theories of consciousness more effectively, it is necessary to give an emergent character, not jumping from the quantum level to the psychic, but explaining the mechanism of the emergence of systemic properties during the sequential transition between different ontological regions of existence, including physical, chemical, biological, neurophysiological and psychic.

We introduce a general representation of unary hyperintensional modalities and study various hyperintensional modal logics based on the representation. It is shown that the major approaches to hyperintensionality known from the literature, that is state-based, syntactic and structuralist approaches, all correspond to special cases of the general framework. Completeness results pertaining to our hyperintensional modal logics are established.

The idea that knowledge is conceptually related to practical reasoning is becoming increasingly popular. In defending this idea, philosophers have been relying on a conception of practical reasoning that drastically deviates from one which has been more traditionally advocated in analytic philosophy and which assigns no special role to knowledge. This paper argues that these philosophers have failed to give good reasons for thinking that the conception of practical reasoning they have been assuming is the right one, and that hence (...) they have been rash to conclude that there is a conceptual relation between knowledge and practical reasoning.

Interest in the topic of wisdom-focused education has so far not resulted in empirically validated programs for teaching wisdom. To start filling this void, we explore the emerging empirical evidence concerning the fundamental elements required for understanding how one can foster wisdom, with a particular focus on wise reasoning. We define wise reasoning through a combination of intellectual humility, recognition of world in flux/change, open-mindedness to diverse viewpoints, and search for compromise/integration of diverse perspectives. In this article, we review evidence (...) concerning how wise reasoning can be facilitated through experiences, teaching materials, environments and cognitive strategies. We also focus on educators, reviewing emerging evidence on how the process of explaining and guiding others impacts one’s wisdom. We conclude by discussing the development of wisdom-focused education, proposing that greater attention to the situational demands and the variability in wisdom-related characteristics across social contexts should play a critical role in its development.

There is an ongoing controversy in philosophy about the connection between explanation and inference. According to Bayesians, explanatory considerations should be given weight in determining which inferences to make, if at all, only insofar as doing so is compatible with Strict Conditionalization. Explanationists, on the other hand, hold that explanatory considerations can be relevant to the question of how much confidence to invest in our hypotheses in ways which violate Strict Conditionalization. The controversy has focused on normative issues. This paper (...) investigates experimentally the descriptive question of whether judgments of the explanatory goodness of hypotheses do play a role when people revise their degrees of belief in those hypotheses upon the receipt of new evidence. We present the results of three experiments that together strongly support the predictive superiority of the explanationist position. (shrink)

This paper argues—contra some Austro-libertarians—that whether a given exchange is welfare-enhancing or welfare-diminishing does not depend on whether that exchange is just or unjust, respectively. Rather, we suggest that in light of our two thought experiments, Austro-libertarianism has at least a pro tanto reason to conceive of justice and welfare as two logically distinct ideals. This would in turn, most interestingly, predict the possibility of (a) just but welfare-diminishing exchanges and (b) unjust but welfare-enhancing ones. Upon considering possible rejoinders to (...) our points, we suggest that Austro-libertarians abandon a justice-based notion of welfare. (shrink)

Conditionals whose antecedent and consequent are not somehow internally connected tend to strike us as odd. The received doctrine is that this felt oddness is to be explained pragmatically. Exactly how the pragmatic explanation is supposed to go has remained elusive, however. This paper discusses recent philosophical and psychological work that attempts to account semantically for the apparent oddness of conditionals lacking an internal connection between their parts.

The article introduces substructural epistemic logics of belief supported by evidence. The logics combine normal modal epistemic logics with distributive substructural logics. Pieces of evidence are represented by points in substructural models and availability of evidence is modelled by a function on the point set. The main technical result is a general completeness theorem. Axiomatisations are provided by means of two-sorted Hilbert-style calculi. It is also shown that the framework presents a natural solution to the problem of logical omniscience.

Van Fraassen (1989) argues that Inference to the Best Explanation is incoherent in the sense that adopting it as a rule for belief change will make one susceptible to a dynamic Dutch book. The present paper argues against this. A strategy is described that allows us to infer to the best explanation free of charge.

The standard approach to the so-called paradoxes of identity has been to argue that these paradoxes do not essentially concern the notion of identity but rather betray misconceptions on our part regarding other metaphysical notions, like that of an object or a property. This paper proposes a different approach by pointing to an ambiguity in the identity predicate and arguing that the concept of identity that figures in many ordinary identity claims, including those that appear in the paradoxes, is not (...) the traditional philosophical concept but one that can be defined in terms of relevant similarity. This approach to the paradoxes will be argued to be superior to the standard one. (shrink)

This paper considers Kamp and Partee's account of graded membership within a conceptual spaces framework and puts the account to the test in the domain of colors. Three experiments are reported that are meant to determine, on the one hand, the regions in color space where the typical instances of blue and green are located and, on the other hand, the degrees of blueness/greenness of various shades in the blue–green region as judged by human observers. From the locations of the (...) typical blue and typical green regions in conjunction with Kamp and Partee's account follow degrees of blueness/greenness for the color shades we are interested in. These predicted degrees are compared with the judged degrees, as obtained in the experiments. The results of the comparison support the account of graded membership at issue. (shrink)

The Lottery Paradox and the Preface Paradox both involve the thesis that high probability is sufficient for rational acceptability. The standard solution to these paradoxes denies that rational acceptability is deductively closed. This solution has a number of untoward consequences. The present paper suggests that a better solution to the paradoxes is to replace the thesis that high probability suffices for rational acceptability with a somewhat stricter thesis. This avoids the untoward consequences of the standard solution. The new solution will (...) be defended against a seemingly obvious objection. 1 The paradoxes of rational acceptability 2 The standard solution 3 A new solution to the paradoxes 4 Basic assumptions 5 The new solution defended 6 Conclusion 7 Appendix.

In previous published research (“Conditionals and Inferential Connections: A Hypothetical Inferential Theory,” Cognitive Psychology, 2018), we investigated experimentally what role the presence and strength of an inferential connection between a conditional’s antecedent and consequent plays in how people process that conditional. Our analysis showed the strength of that connection to be strongly predictive of whether participants evaluated the conditional as true, false, or neither true nor false. In this article, we re-analyse the data from our previous research, now focussing on (...) the semantics of conditionals rather than on how they are processed. Specifically, we use those data to compare the main extant semantics with each other and with inferentialism, a semantics according to which the truth of a conditional requires the presence of an inferential connection between the conditional’s component parts.
