All techniques and concepts are presented with clear, comprehensive explanations and numerous, carefully constructed examples. Its flexible organization (all chapters are complete and self-contained) allows instructors the freedom to cover the topics they want in the order they choose.

The question I consider is this: -/- The Question: Can two people–who are, and realize they are, intellectually virtuous to about the same degree–both be rational in continuing knowingly to disagree after full disclosure (by each to the other of all the relevant evidence they can think of) while at the same time thinking that the other may well be rational too? -/- I distinguish two kinds of rationality–internal and external–and argue in section 1 that, whichever kind we have in (...) mind, the answer to The Question is ‘yes’ (though that positive answer is less wholehearted in the case of external rationality). Then, in section 2, I briefly make some more general remarks about when discovering a disagreement provides a defeater and when it doesn't. In the final section, I consider an important objection to the answer given in section 1 to The Question. (shrink)

This collection of essays examines the ways in which disputes and controversies about the application of scientific knowledge are resolved. Four concrete examples of public controversy are considered in detail: the efficacy of Laetrile, the classification of homosexuality as a disease, the setting of safety standards in the workplace, and the utility of nuclear energy as a source of power. The essays in this volume show that debates about these cases are not confined to matters of empirical fact. Rather, as (...) is seen with most scientific and technical controversies, they focus on and are structured by complex ethical, economic, and political interests. Drs. Engelhardt and Caplan have brought together a distinguished group of scholars from the sciences and humanities, who sketch a theory of scientific controversy and attempt to provide recommendations about the ways in which both scientists and the public ought to seek more informed resolutions of highly contentious issues in science and technology. Scientific Controversies is offered as a contribution to the better understanding of the roles of both science and nonscientific interests in disputes and controversies pertaining to science and technology.

Predication is an indisputable part of our linguistic behavior. By contrast, the metaphysics of predication has been a matter of dispute ever since antiquity. According to Plato—or at least Platonism, the view that goes by Plato’s name in contemporary philosophy—the truths expressed by predications such as “Socrates is wise” are true because there is a subject of predication (e.g., Socrates), there is an abstract property or universal (e.g., wisdom), and the subject exemplifies the property.1 This view is supposed to be (...) general, applying to all predications, whether the subject of predication is a person, a planet, or a property.2 Despite the controversy surrounding the metaphysics of predication, many theistic philosophers—including the majority of contemporary analytic theists—regard Platonism as extremely attractive. At the same time, however, such philosophers are also commonly attracted to a form of traditional theism that has at its core the thesis that God is an absolutely independent.. (shrink)

Professor Merrie Bergmann presents an accessible introduction to the subject of many-valued and fuzzy logic designed for use on undergraduate and graduate courses in non-classical logic. Bergmann discusses the philosophical issues that give rise to fuzzy logic - problems arising from vague language - and returns to those issues as logical systems are presented. For historical and pedagogical reasons, three-valued logical systems are presented as useful intermediate systems for studying the principles and theory behind fuzzy logic. The major fuzzy logical (...) systems - Lukasiewicz, Gödel, and product logics - are then presented as generalisations of three-valued systems that successfully address the problems of vagueness. A clear presentation of technical concepts, this book includes exercises throughout the text that pose straightforward problems, that ask students to continue proofs begun in the text, and that engage students in the comparison of logical systems.

A three-valued propositional logic is presented, within which the three values are read as ?true?, ?false? and ?nonsense?. A three-valued extended functional calculus, unrestricted by the theory of types, is then developed. Within the latter system, Bochvar analyzes the Russell paradox and the Grelling-Weyl paradox, formally demonstrating the meaninglessness of both.

The Belnap–Dunn logic is a well-known and well-studied four-valued logic, but until recently little has been known about its extensions, i.e. stronger logics in the same language, called super-Belnap logics here. We give an overview of several results on these logics which have been proved in recent works by Přenosil and Rivieccio. We present Hilbert-style axiomatizations, describe reduced matrix models, and give a description of the lattice of super-Belnap logics and its connections with graph theory. We adopt the point of (...) view ofAlgebraic Logic, exploring applications of the general theory of algebraization of logics to the super-Belnap family. In this respect we establish a number of new results, including a description of the algebraic counterparts, Leibniz filters, and strong versions of super-Belnap logics, as well as the classification of these logics within the Leibniz and Frege hierarchies.

Internalists tend to impose on justification higher-level requirements, according to which a belief is justified only if the subject has a higher-level belief (i.e., a belief about the epistemic credentials of a belief). I offer an error theory that explains the appeal of this requirement: analytically, a belief is not justified if we have a defeater for it, but contingently, it is often the case that to avoid having defeaters, our beliefs must satisfy a higher-level requirement. I respond to the (...) objection that externalists who endorse this error theory will be forced to accept a radical form of scepticism. (shrink)

This essay offers a fresh interpretation of Bhartr̥hari’s concept of “insight”, and of its identification as the object of a sentence in the second kāṇḍa of the Vākyapadīya. Earlier scholars dealing with this topic disagreed on three main points: whether an epistemologically rigorous concept of insight can be found in Bhartr̥hari’s work, or if the notion remains irrevocably vague and equivocal; whether the concept of pratibhā primarily belongs to linguistics, or to action theory; whether Bhartr̥hari’s identification of insight as the (...) object of a sentence should be taken literally or figuratively. Starting from a close analysis of all passages in Bhartr̥hari’s work mentioning pratibhā, I identify, first of all, a univocal understanding of insight, valid throughout the Vākyapadīya, as immediate cognition informed by verbal transmission, in other words as a form of practical knowledge, non-representational yet essentially productive and dynamic. Showing, on this basis, how Bhartr̥hari’s understanding of language at the level of sentences is pragmatic rather than referential, I demonstrate, against the view prevalent in the late grammatical tradition, that a literal interpretation of his provocative statement on pratibhā as vākyārtha remains perfectly plausible. This thesis is further corroborated by the consideration of post-Bhartr̥hari philosophical sources elaborating on his ideas, which allow us better to understand in what sense pratibhā can legitimately be thought of as cognition “without an object”.

Radical skepticism endorses the extreme claim that large swaths of our ordinary beliefs, such as those produced by perception or memory, are irrational. The best arguments for such skepticism are, in their essentials, as familiar as a popular science fiction movie and yet even seasoned epistemologists continue to find them strangely seductive. Moreover, although most contemporary philosophers dismiss radical skepticism, they cannot agree on how best to respond to the challenge it presents. In the tradition of the 18th century Scottish (...) philosopher, Thomas Reid, Radical Skepticism and Epistemic Intuition joins this discussion by taking up four main tasks. First, it identifies the strongest arguments for radical skepticism, namely, underdetermination arguments, which emphasize the gap between our evidence and our ordinary beliefs based on that evidence. Second, it rejects all inferential or argument-based responses to radical skepticism, which aim to lay out good noncircular reasoning from the evidence on which we base our ordinary beliefs to the conclusion that those beliefs are probably true. Third, it develops a commonsense noninferential response to radical skepticism with two distinctive features: it consciously and extensively relies on epistemic intuitions, which are seemings about epistemic goods, such as knowledge and rationality, and it can be endorsed without difficulty by both internalists and externalists in epistemology. Fourth, and finally, it defends this commonsense epistemic-intuition-based response to radical skepticism against a variety of objections, including those connected with underdetermination worries, epistemic circularity, disagreement problems, experimental philosophy, and concerns about whether it engages skepticism in a sufficiently serious way.

There are relatively few empirical studies on the impacts of corporate social responsibility policies and programs. This article addresses the research gap by analyzing the incidence of, and the conditions that affect, decoupling among CSR policies, implementation of CSR programs, and CSR impacts for various environmental and social issues. Complete decoupling is a condition of full divergence among policies, programs, and impacts amounting to purely ceremonial CSR. Using ratings from a sustainability rating agency on a sample of about 1,000 large (...) companies in 24 countries, the authors find empirical evidence not supporting a conclusion of complete decoupling. The empirical evidence suggests four levels of nondivergence in the sample. First, for most CSR issues examined, CSR policies of high quality do have relatively strong effects on CSR implementation. Second, CSR programs of high quality do have relatively strong effects on CSR impacts. Third, for most CSR issues, even low-quality CSR policies enforce the incidence and quality of programs in comparison with having no policy at all. Fourth, weak programs have more impact on the realization of CSR goals than having no program at all. The authors also find that the quality of CSR reporting and locating the responsibility for CSR at the board level reduce decoupling by strengthening the quality of CSR programs. (shrink)

This paper presents a unified framework that explains and extends the already successful applications of the Leibniz operator, the Suszko operator, and the Tarski operator in recent developments in abstract algebraic logic. To this end, we refine Czelakowski’s notion of an S-compatibility operator, and introduce the notion of coherent family of S-compatibility operators, for a sentential logic S. The notion of coherence is a restricted property of commutativity with inverse images by surjective homomorphisms, which is satisfied by both the Leibniz (...) and the Suszko operators. We generalize several constructions and results already existing for the mentioned operators; in particular, the well-known classes of algebras associated with a logic through each of them, and the notions of full generalized model of a logic and a special kind of S-filters. We obtain a General Correspondence Theorem, extending the well-known one from the theory of protoalgebraic logics to arbitrary logics and to more general operators, and strengthening its formulation. We apply the general results to the Leibniz and the Suszko operators, and obtain several characterizations of the main classes of logics in the Leibniz hierarchy by the form of their full generalized models, by old and new properties of the Leibniz operator, and by the behaviour of the Suszko operator. Some of these characterizations complete or extend known ones, for some classes in the hierarchy, thus offering an integrated approach to the Leibniz hierarchy that uncovers some new, nice symmetries.

This article questions the place of the child in the metaphysics and imaginary of Western colonization, racialization, and decolonization. In the last chapter of The Wretched of the Earth by Frantz Fanon, children appear not only as victims but also as a problem for which Fanon struggles to account as a theorist of decolonization as much as a psychiatric practitioner. Through a reading of one of the cases, this article interrogates the ways in which colonization attempts to infantilize colonized populations (...) while erasing childhood, and the ways in which decolonization meets colonization by regarding childhood in the end as a misfortune. The work of decolonization, to proceed, thus would demand us to rethink childhood, and in doing so break free of Western metaphysics. (shrink)

El presente libro se inicia con una breve reflexión sobre la actitud de los intelectuales en América Latina ante la coyuntura actual, señalando las aportaciones y confusiones de su dicurso teórico y tratando de rescatar las formas de expresión del pensamiento crítico; psra esto se considera la vigencia de la dialéctica como lenguaje. Además, se pretende incursionar sobre las relaciones entre individuos y colectivo, y sobre cuestiones metodológicas para el estudio de sujetos sociales; se incorporan el problema de análisis de (...) variables desde la perspectiva de las mediaciones, y una reflexión sobre la lógica del discurso económico para mostrar cómo implica el olvido del sujeto. Constituyen estos trabajos un esfuerzo de aplicación de la postura racional de nuevas posibilidades de reflexión teórica que contribuyan a enriquecer el discurso, aunque conscientes de su carácter todavía exploratorio.
