Some hold that W.K. Clifford's arguments are inconsistent, appealing to the disvalue of likely consequences of nonevidential belief-formation, while also insisting that the consequences are irrelevant to the wrongness of so believing. My thesis is that Clifford's arguments are consistent; one simply needs to be clear on the role consequences play in the "Ethics of Belief" (and, for that matter, in William James's "The Will to Believe"). The consequences of particular episodes of nonevidential belief-formation are, as (...) Clifford insists, irrelevant to the epistemic, and so moral, status of believing. The moral matter is that adopting a policy of nonevidential belief-formation constitutes commitment to antithetical principles, viz. (i) our antecedent moral obligation to minimize the risk of harming ourselves and others and (ii) the flagrant disregard for (i) entailed by employing a policy of risk, i.e. nonevidentialism. Clifford's arguments should be read as demonstrating that a nonevidentialist approach to belief-management constitutes the kind of risk that, in fact, is at odds with this antecedent moral obligation - hence the discussion of likely consequences, despite his claims that they are irrelevant to the moral status of the beliefs yielding them. They are irrelevant to the moral status of nonevidentialism but not irrelevant to the fact of risk. The moral impermissibility of nonevidentialism inheres in the inconsistency of it and our antecedent moral obligations, not in the value or disvalue of the particular consequences of that belief-management style.

This paper was presented at the 26th International Wittgenstein Symposium on “Knowledge and Belief”, Kirchberg am Wechsel, Austria (3rd - 10th August 2003). The focus of study is a dialogue situation in which one party holds that P while the other holds that ~P. A simple way to establish harmony between the parties in dialogue is to insist that each should include the other’s point of view. This is unsatisfactory because it results in an inconsistent set of beliefs. (...) Clarity is essential, therefore, on how to deal with inconsistency. In this paper, I will proceed in two steps. In the first, I will indicate how some attempts at trying to manage contradictions in terms of ontology remain unsatisfactory. In the second step, I will introduce and evaluate another way in terms of belief and acceptance. I make an original application of L.J. Cohen’s distinction between belief and acceptance, the former being a matter of feeling, the latter a matter of policy in reasoning. (shrink)

I present a possible worlds semantics for a hyperintensional belief revision operator, which reduces the logical idealization of cognitive agents affecting similar operators in doxastic and epistemic logics, as well as in standard AGM belief revision theory. (Revised) belief states are not closed under classical logical consequence; revising by inconsistent information does not perforce lead to trivialization; and revision can be subject to ‘framing effects’: logically or necessarily equivalent contents can lead to different revisions. Such results (...) are obtained without resorting to non-classical logics, or to non-normal or impossible worlds semantics. The framework combines, instead, a standard semantics for propositional S5 with a simple mereology of contents. (shrink)

Reasoning and change over inconsistent knowledge bases is of utmost relevance in areas like medicine and law. Argumentation may bring the possibility to cope with both problems. Firstly, by constructing an argumentation framework from the inconsistent KB, we can decide whether to accept or reject a certain claim through the interplay among arguments and counterarguments. Secondly, by handling dynamics of arguments of the AF, we might deal with the dynamics of knowledge of the underlying inconsistent KB. Dynamics (...) of arguments has recently attracted attention and although some approaches have been proposed, a full axiomatization within the theory of belief revision was still missing. A revision arises when we want the argumentation semantics to accept an argument. Argument Theory Change encloses the revision operators that modify the AF by analyzing dialectical trees—arguments as nodes and attacks as edges—as the adopted argumentation semantics. In this article, we present a simple approach to ATC based on propositional KBs. This allows to manage change of inconsistent KBs by relying upon classical belief revision, although contrary to it, consistency restoration of the KB is avoided. Subsequently, a set of rationality postulates adapted to argumentation is given, and finally, the proposed model of change is related to the postulates through the corresponding representation theorem. Though we focus on propositional logic, the results can be easily extended to more expressive formalisms such as first-order logic and description logics, to handle evolution of ontologies. (shrink)

The existential insecurity of human beings has induced them to create protective spheres of symbols: myths, religions, values, belief systems, theories, etc. Rationality is one of the key factors contributing to the construction of civilisation in technical and symbolic terms. As Hankiss (2001) has emphasised, protective spheres of symbols may collapse – thus causing a profound social crisis. Social and political transformations had a tremendous impact at the end of the 20th century. As a result, management theories have (...) been revised in order to deal with transition and uncertainty. Francis Fukuyama's (2000) approach is supportive of hierarchical organisation as the best solution when facing a 'disruption'. The notion of Homo Hierarchicus has been based on, allegedly, rational presumptions. This paper contributes to the discussion on hierarchy within contemporary organisations. It criticises so-called 'natural' and 'rational' necessities justifying hierarchy. A key issue identified by the paper is the formalisation of language in claiming value-free knowledge and 'detached' observation as the basis for neutral rationality and aspired efficiency. This should be seriously reconsidered as hindering rather than aiding understanding of social complexity. All in all, Homo Hierarchicus appears to be misleading rather than helping symbolic sphere or construct. (shrink)

There is a principle in things, about which we cannot be deceived, but must always, on the contrary, recognize the truth – viz. that the same thing cannot at one and the same time be and not be": with these words of the Metaphysics, Aristotle introduced the Law of Non-Contradiction, which was to become the most authoritative principle in the history of Western thought. However, things have recently changed, and nowadays various philosophers, called dialetheists, claim that this Law does not (...) hold unrestrictedly – that in peculiar circumstances the same thing may at the same time be and not be, and contradictions may obtain in the world. This book opens with an examination of the famous logical paradoxes that appear to speak on behalf of contradictions (e.g., the Liar paradox, the set-theoretic paradoxes such as Cantor’s and Russell’s), and of the reasons for the failure of the standard attempts to solve them. It provides, then, an introduction to paraconsistent logics – non-classical logics in which the admission of contradictions does not lead to logical chaos –, and their astonishing applications, going from inconsistent data base management to contradictory arithmetics capable of circumventing Gödel’s celebrated Incompleteness Theorem. The final part of the book discusses the philosophical motivations and difficulties of dialetheism, and shows how to extract from Aristotle’s ancient words a possible reply to the dialetheic challenge. How to Sell a Contradiction will appeal to anyone interested in non-classical logics, analytic metaphysics, and philosophy of mathematics, and especially to those who consider challenging our most entrenched beliefs the main duty of philosophical inquiry.

This paper addresses how multiple individual credences on logically related issues should be aggregated into collective binary beliefs. We call this binarizing belief aggregation. It is vulnerable to dilemmas such as the discursive dilemma or the lottery paradox: proposition-wise independent aggregation can generate inconsistent or not deductively closed collective judgments. Addressing this challenge using the familiar axiomatic approach, we introduce general conditions on a binarizing belief aggregation rule, including rationality conditions on individual inputs and collective outputs, and (...) determine which rules (if any) satisfy different combinations of these conditions. Furthermore, we analyze similarities and differences between our proofs and other related proofs in the literature and conclude that the problem of binarizing belief aggregation is a free-standing aggregation problem not reducible to judgment aggregation or probabilistic opinion pooling.

The problem of how to accommodate inconsistencies has attracted quite a number of researchers, in particular, in the area of database theory. The problem is also of concern in the study of belief change. For inconsistent beliefs are ubiquitous. However, comparatively little work has been devoted to discussing the problem in the literature of belief change. In this paper, I examine how adequate the AGM theory is as a logical framework for belief change involving inconsistencies. The (...) technique is to apply to Grove’s sphere system, a semantical representation of the AGM theory, logics that do not infer everything from contradictory premises, viz., paraconsistent logics. I use three paraconsistent logics and discuss three sphere systems that are based on them. I then examine the completeness of the postulates of the AGM theory with respect to the systems. At the end, I discuss some philosophical implications of the examination. (shrink)

The Anxiety-Buffering Properties of Cultural and Subcultural Worldviews: Terror Management Processes among Juvenile Delinquents Terror management research indicates that people reminded of mortality strongly affirm values and standards consistent with their cultural worldview and distance themselves from values and standards inconsistent with it. However, limited research has addressed how individuals holding beliefs inconsistent with the dominant worldview cope with death-related anxiety. The present article aims to determine which worldview subcultural groups rely on when reminded of mortality: (...) mainstream or subcultural? Juvenile delinquents living in residential reformatories in Poland were invited to participate in a terror management study examining the anxiety-buffering strategies of individuals belonging to a group largely outside mainstream culture. Following reminders of mortality, juvenile delinquents increased support for values consistent with the mainstream cultural worldview and decreased support for values consistent with the subcultural worldview, as compared to control conditions. The present results suggest that when faced with existential threat, the subcultural worldview does not provide an adequate anxiety buffer, leading members of this subcultural group to display increased identification with mainstream cultural values. Additionally, participants' state anxiety following death reminders was mediated by mainstream cultural worldview defense. (shrink)

The most pressing difficulty coherentism faces is, I believe, the problem of justified inconsistent beliefs. In a nutshell, there are cases in which our beliefs appear to be both fully rational and justified, and yet the contents of the beliefs are inconsistent, often knowingly so. This fact contradicts the seemingly obvious idea that a minimal requirement for coherence is logical consistency. Here, I present a solution to one version of this problem.

Suppose that I hold a ticket in a fair lottery and that I believe that my ticket will lose [L] on the basis of its extremely high probability of losing. What is the appropriate epistemic appraisal of me and my belief that L? Am I justified in believing that L? Do I know that L? While there is disagreement among epistemologists over whether or not I am justified in believing that L, there is widespread agreement that I do not (...) know that L. I defend the two-pronged view that I am justified in believing that my ticket will lose and that I know that it will lose. Along the way, I discuss four different but related versions of the lottery paradox—The Paradox for Rationality, The Paradox for Knowledge, The Paradox for Fallibilism, and The Paradox for Epistemic Closure—and offer a unified resolution of each of them.

This thesis proposes and presents two new models for belief representation and belief revision. The first model is the B-structures model which relies on a notion of partial language splitting and tolerates some amount of inconsistency while retaining classical logic. The model preserves an agent's ability to answer queries in a coherent way using Belnap's four-valued logic. Axioms analogous to the AGM axioms hold for this new model. The distinction between implicit and explicit beliefs is represented and psychologically (...) plausible, computationally tractable procedures for query answering and belief base revision are obtained. ;The second model presents a method for relevance sensitive non-monotonic inference from belief sequences which incorporates insights pertaining to prioritized inference and relevance sensitive, inconsistency tolerant belief revision. Our model uses a finite, logically open sequence of propositional formulas as a representation for beliefs and defines a notion of inference from maxiconsistent subsets of formulas guided by two orderings: a temporal sequencing and an ordering based on relevance relations between the conclusion and formulas in the sequence. The relevance relations are ternary as opposed to standard binary axiomatizations. The inference operation thus defined easily handles iterated revision by maintaining a revision history, blocks the derivation of inconsistent answers from a possibly inconsistent sequence and maintains the distinction between explicit and implicit beliefs. In doing so, it provides a finitely representable formalism and a plausible model of reasoning for automated agents. (shrink)

Fallacious anthropomorphic attributions such as 'risky technology' take ethical accountability out of the hands of managers and relegate it to the deterministic or accidental outcomes of complex 'high risk technology'. Equally fallacious mechanistic terms such as 'organisational inertia' are borrowed from physics to apply to human organisations. The responsibility for ethically accountable decision-making is taken out of human hands and either ascribed to the mythological entity "Technology" or to the mythological bureaucratic organisation which functions as if it follows the laws (...) of physics. I argue in contrast that disasters can be prevented by demythologising the belief systems that pervade risk management literature. Risk management must reclaim ethical accountability by replacing notions such as 'risky technology', 'high risk technology', 'risky work' and 'bureaucratic drift' with 'risky assessment', 'risky management', 'risky choice' and 'multiple responsibility'.

A cross-cultural empirical study is reported in this article which looks at ethical beliefs and behaviours among French and German managers, and compares this with previous studies of U.S. and Israeli managers using a similar questionnaire. Comparisons are made between what managers say they believe, and what they do, between managers and their peers' attitudes and behaviours, and between perceived top management attitudes and the existence of company policy. In the latter, significant differences are found by national ownership of (...) the company rather than the country in which it is situated. Significant differences are found, for both individual managers by nationality, and for companies by nationality of parents, in the area of organizational loyalty. The attitude towards accepting gifts and favours in exchange for preferential treatment, as a measure of societal values, is also found to show significant differences between national groups. However, no significant differences are found for measures for group loyalty, conflict between organizational and group loyalty and for conflicts between self and group/organization. The findings have implications for cross-border management decision strategies regarding such issues as receiving and giving of gifts, and the management of relations between local employees and international organizations which may be affected by differences in attitude to corporate loyalty.

Our behavior doesn't always match the beliefs attributed to us, and sometimes the mismatch raises questions about what our beliefs actually are. I compare two approaches to such cases, and argue in favor of the one which allows some belief-attributions to lack a determinate truth-value. That approach avoids an inappropriate assumption about cognitive activity: namely, that whenever we fail in performing one cognitive activity, there is a distinct cognitive activity at which we succeed. The indeterminacy-allowing approach also meshes well (...) with an attractive view of folk-psychology: that ascriptions can help shape the attitudes they report. (shrink)

This study examines the ethical beliefs and behavior of a sample of Israeli managers (n=97) and comparable data from the United States. Israeli managers rated themselves both highly ethical and more ethical than their peers. These results are similar to those found for the U.S., and indicate that the best predictor of respondents' ethical behavior is their beliefs and perceptions concerning their peers' behavior. In addition, this study examines the managers' predisposition to promote social responsibility by joining social networks of (...) managers and other business people, established for that purpose. Seventy-eight percent are of the opinion that networks for the promotion of social responsibility in business are needed and 57% are ready to join them. (shrink)

We examine the link between the growing emphasis on corporate social responsibility at the organizational level and beliefs about social responsibility at work (SRW) expressed by individuals. Drawing from theories of professionalism and diffusion of innovations (including practices and beliefs), we advance hypotheses about beliefs of managers and non-managers in 11 countries at two time periods, and use a unique international data set to test our hypotheses. Our general prediction that managers would score higher than non-managers on a measure of (...) SRW was not supported. However, further analysis revealed a more complex relationship moderated by the contextual factors of time frame and country inequality level. We discuss implications and extensions for future research. (shrink)

This paper investigates whether local religious beliefs have a significant impact on the practice of earnings management. We extend the existing literature on the role of firm characteristics in mitigating earnings management by showing that local religious beliefs significantly impact the practice of earnings management. Specifically, exploring firms located in the U.S. counties that vary from 2000 through 2010, we document the negative relationship between religiosity and earnings management using multivariate regression analysis. Our results show that (...) firms in counties with strong religious social norms are less likely to engage in earnings management. Furthermore, we attempt to mitigate endogeneity concerns by employing a modified Difference-Differences model and Propensity score matching methods. We find that the negative effects of religion on earnings management still hold. Overall, these findings emphasize the empirical relevance of the association between the local social norms and earnings manipulations. (shrink)

We relax the assumption that priors are common knowledge, in the standard model of games of incomplete information. We make the realistic assumption that the players are boundedly rational: they base their actions on finite-order belief hierarchies. When the different layers of beliefs are independent of each other, we can retain Harsányi's type-space, and we can define straightforward generalizations of Bayesian Nash Equilibrium and Rationalizability in our context. Since neither of these concepts is quite satisfactory, we propose a hybrid (...) concept, Mirage Equilibrium, providing us with a practical tool to work with inconsistent belief hierarchies. When the different layers of beliefs are correlated, we must enlarge the type-space to include the parametric beliefs. This presents us with the difficulty of the inherent openness of finite belief subspaces. Appealing to bounded rationality once more, we posit that the players believe that their opponent holds a belief hierarchy one layer shorter than they do and we provide alternative generalizations of BNE and Rationalizability. Finally, we show that, when beliefs are degenerate point beliefs, the definition of Mirage Equilibrium coincides with that of the generalized BNE. (shrink)

Academic literature addressing the topic of business ethics has paid little attention to cross-cultural studies of business ethics. Uncertainty exists concerning the effect of culture on ethical beliefs. The purpose of this research is to compare the ethical beliefs of managers operating in South Africa and Australia. Responses of 52 managers to a series of ethical scenarios were sought. Results indicate that despite differences in socio-cultural and political factors there are no statistically significant differences between the two groups regarding their (...) own ethical beliefs. Results thus support the view that culture has little or no impact on ethical beliefs. (shrink)

McKay & Dennett (M&D) identify positive illusions as fulfilling the criteria for an adaptive misbelief, but could there be other types of beliefs that may qualify as adaptive misbeliefs? My commentary addresses this and other questions through identifying belief in free will as a potential candidate as an adaptive misbelief.

Whether people possess free will has been a long-lasting philosophical debate. Recent attention in social psychology has been given to the behavioral consequences of believing in free will. Research has demonstrated that manipulating free will beliefs has implications for many social behaviors. For example, free will belief manipulations have been associated with cheating, aggressiveness, and prejudice. Despite this work, some of these findings have failed to replicate. Testing theoretical predictions, such as whether believing in free will influences behavior, depends (...) on theoretical, auxiliary, statistical, and inferential assumptions (TASI). In this paper we apply the TASI category of assumptions to the free will belief debate. In doing so we demonstrate why these assumptions should be considered when appraising the influence of free will belief manipulations on free will beliefs and behavior. To provide a nuanced view of free will beliefs, we believe researchers should pay careful attention to these critical assumptions. (shrink)

William Simkulet has recently criticised Colgrove et al’s defence against what they have called inconsistency arguments—arguments that claim opponents of abortion (OAs) act in ways inconsistent with their underlying beliefs about human fetuses (eg, that human fetuses are persons at conception). Colgrove et al presented three objections to inconsistency arguments, which Simkulet argues are unconvincing. Further, he maintains that OAs who hold that the fetus is a person at conception fail to act on important issues such as the plight (...) of frozen embryos, poverty and spontaneous abortion. Thus, they are morally negligent. In response, we argue that Simkulet has targeted a very narrow group of OAs, and so his criticisms are inapplicable to most OAs. We then explain why his responses to each of Colgrove et al’s objections do not succeed, even for this restricted group. Finally, we note that Simkulet fails to provide evidence for his claims regarding OAs’ supposed failures to act, and we show that OAs veritably do invest resources into these important issues. We conclude that Colgrove et al’s reasons for rejecting inconsistency arguments (en masse) remain intact. (shrink)

Most opposition to induced abortion turns on the belief that human fetuses are persons from conception. On this view, the moral status of the fetus alone requires those in a position to provide aid—gestational mothers—to make tremendous sacrifices to benefit the fetus. Recently, critics have argued that this pro-life position requires more than opposition to induced abortion. Pro-life theorists are relatively silent on the issues of spontaneous abortion, surplus in vitro fertilisation human embryos, and the suffering and death of (...) born persons due to lack of access to food, shelter and medical care. Colgrove et al call such arguments inconsistency arguments, arguing they ‘do not matter’ and mischaracterise them as ad hominem attacks. Here, I argue these are better understood as moral dilemmas. While some critics argue pro-life inaction is evidence that they do not really believe human fetuses are persons, I contend this inaction is likely the result of resolvable confusion rather than moral negligence.

Abstract In this paper I discuss one apparent counterexample to the rationality constraint on belief ascription. The fact that there are inconsistent believers does not seem compatible with the idea that only rational creatures can be ascribed beliefs. I consider Davidson's explanation of the possibility of inconsistent believers and claim that it involves a reformulation of the rationality constraint in terms of the believers' subscription to norms of rationality. I shall argue that Davidson's strategy is partially successful, (...) but that the emphasis on the notion of subscription badly fits with the motivations behind his theory of interpretation.

Drawing on justice theory and upper echelons perspective, this study develops and tests an integrative model linking justice to the implementation of IT-enabled supply chain information integration through the top management. Specifically, the study investigates the effects of the three facets of justice—distributive, procedural, and interactional justice—on the two dimensions of IeSCII, and examines the mediating influences of top management beliefs and top management participation in these relationships. Using structural equation modeling to analyze data collected from 190 (...) firms in China, the study documents that interactional justice positively affects both TMB and TMP, while procedural justice positively affects TMB in the IeSCII implementation process. In contrast, distributive justice is not significantly related to either TMB or TMP, but is positively associated with information sharing. The results also show that procedural justice positively affects TMB, which then positively affects TMP in IeSCII. Furthermore, the study finds significant mediating effects of TMB and TMP in the relationship between interactional justice and IeSCII. The theoretical and managerial implications of this study are discussed. (shrink)

In section I, I argue that the principal reason why inconsistency is a fault is that it involves having at least one false belief. In section 2, I argue that inconsistency need not be a serious epistemic fault. The argument in section 2 is based on the notion that what matters epistemically is always in the final analysis an item's effect on attaining the goal of truth. In section 3 I describe two cases in which it is best from (...) an epistemic point of view to knowingly retain inconsistent beliefs. In section 4 my goal is to put into perspective the charge that relativism ought to be rejected because it involves one in inconsistency. (shrink)

The relationship between inconsistency and Lehrerian coherence is scrutinized. Like most coherence theorists of epistemic justification, Lehrer contends that consistency is necessary for coherence. Despite this contention, minimally inconsistent belief-sets prove coherent and rationally acceptable on Lehrer's account of coherence. Lehrer is left with the following dilemma: If consistency is necessary for coherence, then (i) he must revise his account of coherence accordingly and, more importantly, (ii) such coherence is nof necessary for justification, since intuitively we are justified (...) in accepting such minimally inconsistent belief-sets. If, on the other hand, minimally inconsistent acceptance systems can be coherent, then to prevent pairwise inconsistent statements form readily cohering with such systems, Lehrer must deny that rational acceptance is closed under deduction.

“Probably Peirce’s best-known works are the first two articles in a series of six that originally were collectively entitled Illustrations of the Logic of Science and published in Popular Science Monthly from November 1877 through August 1878. The first is entitled ‘The Fixation of Belief’ and the second is entitled ‘How to Make Our Ideas Clear.’ In the first of these papers Peirce defended, in a manner consistent with not accepting naive realism, the superiority of the scientific method over (...) other methods of overcoming doubt and ‘fixing belief.’” — Robert Burch, “Charles Sanders Peirce,” entry in the Stanford Encyclopedia of Philosophy (2021 revision) -/- “Pragmatist epistemologies often explore how we can carry out inquiries in a self-controlled and fruitful way. (Where much analytic epistemology centres around the concept of knowledge, considered as an idealised end-point of human thought, pragmatist epistemology centres around the concept of inquiry, considered as the process of knowledge-seeking and how we can improve it.) So pragmatists often provide rich accounts of the capacities or virtues that we must possess in order to inquire well, and the rules or guiding principles that we should adopt. A canonical account is Peirce’s classic early paper ‘The Fixation of Belief‘. Here Peirce states that inquiry is a struggle to replace doubt with “settled belief“, and that the only method of inquiry that can make sense of the fact that at least some of us are disturbed by inconsistent beliefs, and will subsequently reflect upon which methods of fixing belief are correct is the Method of Science, which draws on the Pragmatic Maxim described above. This contrasts with three other methods of fixing belief: i) refusing to consider evidence contrary to one’s favored beliefs (the Method of Tenacity), ii) accepting an institution’s dictates (the Method of Authority), iii) developing the most rationally coherent or elegant-seeming belief-set (the A Priori Method).“ — Catherine Legg, “Pragmatism,” entry in the Stanford Encyclopedia of Philosophy (2021 revision).

We present a model for studying communities of epistemically interacting agents who update their belief states by averaging the belief states of other agents in the community. The agents in our model have a rich belief state, involving multiple independent issues which are interrelated in such a way that they form a theory of the world. Our main goal is to calculate the probability for an agent to end up in an inconsistent belief state due (...) to updating. To that end, an analytical expression is given and evaluated numerically, both exactly and using statistical sampling. It is shown that, under the assumptions of our model, an agent always has a probability of less than 2% of ending up in an inconsistent belief state. Moreover, this probability can be made arbitrarily small by increasing the number of independent issues the agents have to judge or by increasing the group size. A real-world situation to which this model applies is a group of experts participating in a Delphi-study. (shrink)

Inconsistency and contradiction are important concepts. Unfortunately, they are easily confused. A proposition or belief which is inconsistent is one which is self- contradictory and vice-versa. Moreover two propositions or beliefs which are contradictories are inconsistent with each other. Nonetheless it is a mistake to suppose that inconsistency is the same as contradiction.

If a subject’s belief system is inconsistent, does it follow that the subject’s beliefs (all of them) are unjustified? It seems not. But, coherentist theories of justification (at least some of them) imply otherwise, and so, it seems, are open to counterexample. This is the “Problem of Justified Inconsistent Beliefs”. I examine two main versions of the Problem of Justified Inconsistent Beliefs, and argue that coherentists can give at least a promising line of response to each (...) of them. (shrink)

In this paper two systems of AGM-like Paraconsistent Belief Revision are overviewed, both defined over Logics of Formal Inconsistency (LFIs) due to the possibility of defining a formal consistency operator within these logics. The AGM° system is strongly based on this operator and internalize the notion of formal consistency in the explicit constructions and postulates. Alternatively, the AGMp system uses the AGM-compliance of LFIs and thus assumes a wider notion of paraconsistency - not necessarily related to the notion of (...) formal consistency. (shrink)

Expressivism - the sophisticated contemporary incarnation of the noncognitivist research program of Ayer, Stevenson, and Hare - is no longer the province of metaethicists alone. Its comprehensive view about the nature of both normative language and normative thought has also recently been applied to many topics elsewhere in philosophy - including logic, probability, mental and linguistic content, knowledge, epistemic modals, belief, the a priori, and even quantifiers. Yet the semantic commitments of expressivism are still poorly understood and have not (...) been very far developed. As argued within, expressivists have not yet even managed to solve the "negation problem" - to explain why atomic normative sentences are inconsistent with their negations. As a result, it is far from clear that expressivism even could be true, let alone whether it is. Being For seeks to evaluate the semantic commitments of expressivism, by showing how an expressivist semantics would work, what it can do, and what kind of assumptions would be required, in order for it to do it. Building on a highly general understanding of the basic ideas of expressivism, it argues that expressivists can solve the negation problem - but only in one kind of way. It shows how this insight paves the way for an explanatorily powerful, constructive expressivist semantics, which solves many of what have been taken to be the deepest problems for expressivism. But it also argues that no account with these advantages can be generalized to deal with constructions like tense, modals, or binary quantifiers. Expressivism, the book argues, is coherent and interesting, but false. (shrink)
