The argument of this paper is that Kuhn's account of rational theory choice is too permissive and that an account that recognizes the large-scale nature of the system of scientific beliefs is more plausible and has more practical force.

This paper addresses the problems of justifying and explaining beliefs about facts in the context of civil trials. The first section contains some remarks about the nature of adjudicative fact-finding and highlights the communicative features of deciding about facts in judicial context. In Sect. 2, some difficulties and the incompleteness presented by Bayesian and coherentist frameworks, which are taken as methods suitable to solve the above-mentioned problems, are pointed out. In the third section, the purely epistemic approach to the (...) justification and the explanation of beliefs about facts is abandoned and focus is given to the dialectical nature of civil procedure, where the parties and, particularly, the judge have to make their reasoning clear enough to allow a fruitful and efficient debate about facts. For this purpose, a communication/argumentation system is put forward, consisting of fourteen intertwined rules of discourse. The system embodies the fundamental epistemic principle according to which belief is updated given new evidence, is tailored for abductive inferences and is structured on fundamental concepts of civil procedural law. The fourth section presents an empirical application of the system to a real case. (shrink)

The first part of the papaer contains desiderata for a realistic epistemic system as opposed to idealistic ones. One of the main characteristics of idealistic epistemic systems is their deductive infallibility or deductive omniscience. The system presented avoids deductive infallibility though having a strong concept of knowledge. The second part contains the theorems of the system. The system is detailed in so far as it distinguishes between two concepts of belief and one of assumption and interrelates (...) them to the concept of knowledge. Though all concepts satisfy certain consistency criteria the strongest ones hold for the concept of knowledge; whereas a belief in or a assumption (assertion) of a proposition which has inconsistent consequences (not known or believed or assumed by the believer or assumer) does not entail the commitment of believing in (or assuming of) an explicit contradiction. Moreover the system contains a lot of distinctions and details concerning propositions with a second person involved like "a knows that b knows whether p is the case" etc. The third part of the paper contains the semantics of the system which consists of many-valued truth-tables. Since the matrices are finite the system is consistent and decidable. (shrink)

This two-volume work, first published in 1843, was John Stuart Mill's first major book. It reinvented the modern study of logic and laid the foundations for his later work in the areas of political economy, women's rights and representative government. In clear, systematic prose, Mill disentangles syllogistic logic from its origins in Aristotle and scholasticism and grounds it instead in processes of inductive reasoning. An important attempt at integrating empiricism within a more general theory of human knowledge, the work constitutes (...) essential reading for anyone seeking a full understanding of Mill's thought. Volume 1 contains Mill's introduction, which elaborates upon his definition of logic as 'not the science of Belief, but the science of Proof, or Evidence'. It also features discussions of the central components of logical reasoning - propositions and syllogisms - in relation to Mill's theories of inductive reasoning and experimental method. (shrink)

D'Holbach believed that the misery he saw in mankind around him was caused by religion and its superstitious beliefs - that there was a God who controlled destiny and would reward and punish individuals. The System of Nature was written to replace these delusions with a schema of understanding based solely on the physical workings of nature.

In philosophical literature the issue of beliefs has been identified historically with David Hume and common sense. Beliefs are dynamic systems and its resignification is constant. Charles Sanders Pierce would interpret the fixation of beliefs, as those ones which are fixed by means of art, being this a method well-tuned with science. Truths established in beliefs are always probable and dependent on the degree of utility they have. The degree of utility is complemented with comprehension, explanations (...) have multiple causes.

Las verdades establecidas en las creencias son siempre probables y dependen del grado de utilidad que ellas presten. El grado de utilidad se complementa con la comprensión, las explicaciones son multicausales. (shrink)

The papers collected in this volume exemplify some of the trends in current approaches to logic, language and computation. Written by authors with varied academic backgrounds, the contributions are intended for an interdisciplinary audience. The first part of this volume addresses issues relevant for multi-agent systems: reasoning with incomplete information, reasoning about knowledge and beliefs, and reasoning about games. Proofs as formal objects form the subject of Part II. Topics covered include: contributions on logical frameworks, linear logic, and different (...) approaches to formalized reasoning. Part III focuses on representations and formal methods in linguistic theory, addressing the areas of comparative and temporal expressions, modal subordination, and compositionality. (shrink)

Converse contended that the ideological disorganization, attitudi‐nal inconsistency, and limited information of American voters make them a politically disengaged mass, not a responsible electorate. I illustrate the shortcomings of Converse's line of reasoning by showing that he misread his two most prominent examples of the electoral consequences of his theory: voting on the Vietnam War in the 1968 New Hampshire primary, and public opinion about the 1948 Taft‐Hartley Act. In both cases, voters were better able to sort candidates and policies (...) than Converse reported, despite their lack of ideological sophistication or their knowledge of specific legislation. Converse's interpretive errors here stem from mistaken assumptions about information processing and recall, and from questionable normative standards about what constitute meaningful and competent political orientation. His criteria underestimate the public's ability to make responsible choices, and the effect of campaigns on the choosing process. (shrink)

This paper describes a belief understanding system which, taking an interview-text as its input, builds a conceptual representation of a respondent's belief system concerning a given object. Central to the understanding process is the identification of the connections between the object and the believer's goals. A general scheme governing the inference-processes with respect to these object-goal relationships is presented. It is suggested that the implementation of BUS could proceed from Schank's et al Integrated Partial Parsing program. The (...) class='Hi'>system's behavior is illustrated by examining the processing of a fragment of an interview-text. Some implications for the study of belief systems are discussed. (shrink)

“The Nature of Belief Systems” sets forth a Hobson's choice between rule by the politically ignorant masses and rule by the ideologically constrained—which is to say, the doctrinaire—elites. On the one hand, lacking comprehensive cognitive structures, such as ideological “belief systems,” with which to understand politics, most people learn distressingly little about it. On the other hand, a spiral of conviction seems to make it difficult for the highly informed few to see any aspects of politics but those that confirm (...) the cognitive structures that organize their political perceptions. This is a troubling situation for any consequentialist democratic political theory, according to which what is crucial is the electorate's (and subsidiary decision makers') ability to make informed policy judgments, not their possession of willful but uninformed political “attitudes.” Any political theorist who does not take democracy to be an end in itself (regardless of its consequences) should be concerned about Converse's findings.

Systems thinking provides insights into how ideas interact and change, and constructivism is an example of this type of systemic approach. In the 1970s constructivism emphasised the development of mathematical and scientific ideas in children. Recently constructivist ideas are applied much more generally. Here I use this approach to consider beliefs and their role in conflicts and the conditions needed for reconciliation. If we look at Reality in terms of how we construct it as a human cognitive process, we (...) recognise two things. First, that we cannot go beyond our senses and thoughts to what exists independently of us, and second, if we construct what we know we have to take responsibility for this. This inevitably focuses our thinking on the relation we have with the physical and social world, we are a part of the universe rather than apart from it. This paper argues that accepting and understanding these limits of human knowing together with our interconnectedness provide opportunities to understand conflicting positions. To resolve conflict, people with opposing viewpoints have to be prepared to understand each other. That is a challenge because our own reality plays a vital role in our lives, for everything from personal survival to social support. (shrink)

We examine conceptual and methodological problems that arise in the course of the scientific study of possible influences of religious belief on the experience of physical pain. We start by attempting to identify a notion of religious belief that might enter into interesting psychological generalizations involving both religious belief and pain. We argue that it may be useful to think of religious belief as a complex dispositional property that relates believers to a sufficiently thick belief system that encompasses both (...) cognitive and non-cognitive elements. Such a conception of religious belief is more likely to correlate with psychological properties of believers that are both sufficiently shared and sufficiently unique to distinguish their psychology from believers in another religion or from non-believers. If the dispositional psychological property that constitutes religious belief does influence pain, then our analysis suggests that it doesn’t do so directly but rather through one of its occurrent manifestations. We offer a taxonomy of the different ways in which occurrent states of belief or experience may interact with physical pain, and we try to identify those that are more interesting or promising. We then proceed to employ the conceptual framework we developed to some of the existing evidence about the neural and psychological correlates of religious belief and experience, and about the cognitive modulation of physical pain. Finally we turn to analyse two experiments that directly investigated the relation between religious belief and pain. We draw attention to the limitations of existing evidence and end by suggesting directions for future conceptual and empirical inquiry. (shrink)

This paper attempts to revisit how ‘acquaintance’ could bring about belief and how belief becomes knowledge in our language system due to the credential undertaking of truth, justification, evidence, and causal or conceptual preservation. My quest in this paper is to interrogate belief and the cessation of belief (I call this the ‘death of belief’) from the perspective of the doxastic approach of externalism and internalism in the philosophy of language and philosophy of mind. I will attempt to make (...) sense of the nominal appeal (an approach that conserves the process of continuing belief through evidence and conceptualization) to both of these ideas in a sophisticated manner. The linguistic form of using words seems allied to the context sensitivity of the speakers involved in social practices. A tripartite structure pivots the model of linguistic belief, where minds are causally entrenched in a world that stimulates conceptual or internal states, representing how objectivity works. The entanglements of concepts with pictures hinge on conceptual prerequisites to impact the world. (shrink)

The empirical study of belief is emerging at a rapid clip, uniting work from all corners of cognitive science. Reliance on belief in understanding and predicting behavior is widespread. Examples can be found, inter alia, in the placebo, attribution theory, theory of mind, and comparative psychological literatures. Research on belief also provides evidence for robust generalizations, including about how we fix, store, and change our beliefs. Evidence supports the existence of a Spinozan system of belief fixation: one that (...) is automatic and independent of belief rejection. Independent research supports the existence of a system of fragmented belief storage: one that relies on large numbers of causally isolated, context-sensitive stores of belief in memory. Finally, empirical and observational data support at least two systems of belief change. One system adheres, mostly, to epistemological norms of updating; the other, the psychological immune system, functions to guard our most centrally held beliefs from potential inconsistency with newly formed beliefs. Refining our under- standing of these systems can shed light on pressing real-world issues, such as how fake news, propaganda, and brainwashing exploit our psychology of belief, and how best to construct our modern informational world.

This book focuses on the social psychology of belief systems and how they influence perceptions of reality. These belief systems, from politics to religion to science, shape one¿s thoughts and views, but also can be the cause of conflict and disagreement over values, particularly when they are enacted in political policies. ¿ In¿Belief Systems and the Perceptions of Reality, editors Bastiaan Rutjens and Mark Brandt examine the social psychological effects at the heart of the conflict, by bringing together contributions under (...) five themes: Motivated Reasoning; Inequality; Threat; Scientists Interpreting Science; and People Interpreting Science. This book aims to create a more integrated understanding of reality perception and its connection with belief systems, viewed through the lens of social psychology. ¿ The synthesis of expert contributors as well as the literature around social psychology and belief systems makes this a unique resource for students, researchers and academics in behavioural and social sciences, as well as activists and journalists working in this political field.

System justification theory holds that disadvantaged groups rationalize the current social system, even if it is unfavorable to them. Epistemic, relational, and existential needs are factors that explain this phenomenon. However, the literature has not yet examined and explained when disadvantaged groups no longer rationalize current social systems. This study uses a questionnaire survey method to study the moderating effect of collectivism on disadvantaged mindset and system-justifying beliefs. It found that collectivism can influence the predictive effect (...) of disadvantaged mindset on system-justifying beliefs. For people who scored low in collectivism, a disadvantaged mindset can significantly negatively predict system-justifying beliefs; for those who scored high in collectivism, a disadvantaged mindset no longer predicts system-justifying beliefs. Therefore, these results show that collectivist values are important for explaining system justification in disadvantaged groups. When collectivist values decline, the level of rationalization of the social system by disadvantaged groups also decreases. (shrink)

We propose a new class of multiple contraction operations — the system of spheres-based multiple contractions — which are a generalization of Grove’s system of spheres-based (singleton) contractions to the case of contractions by (possibly non-singleton) sets of sentences. Furthermore, we show that this new class of functions is a subclass of the class of the partial meet multiple contractions.

A rational man’s beliefs are not logically consistent, and he does not believe all the logical consequences of his beliefs. This is because in any situational context, we only accept certain believed sentences. Within that context, we insist that sentences be logically consistent, and we accept the logical consequences of the other sentences we accept in that context. But such sentences do not have to be consistent with sentences we accept in other contexts, nor will we always accept (...) in that context the logical consequences of sentences that we accept in other contexts. We go through many different situational contexts in the course of a day. For example, in trying to start a car with a dead battery, explaining why the car won’t start may form one context, while explaining how to start it may form a different context; sentences we accept in the first context may be logically inconsistent with sentences we accept in the second.

People experiencing similar conditions may make different decisions, and their belief systems provide insight about these differences. An example of high‐stakes decision‐making within a complex social context is the Arab Spring, in which large numbers of people decided to protest and even larger numbers decided to stay at home. This study uses qualitative analyses of interview narratives and social media addressing individual decisions to develop a computational model tracing the cognitive decision‐making process. The model builds on work by Abelson and (...) Carroll (1965), Schank and Abelson (1977), and Axelrod (1976) to systematically trace the inferences connecting beliefs to decisions. The findings show that protest decisions were often based on positive emotions such as pride, hope, courage, and solidarity, triggered by beliefs about successful protest and self‐sacrifice. By contrast, decisions to stay at home were triggered by beliefs about safety, state approval, and living conditions. As one participant said, “When I heard about the revolution in Tunisia, my heart was filled with solidarity for the people.” In the words of a non‐participant: “When people are killed, we must be careful. There are more important things than protest: safety and stability.” This study of individual explanations about events identifies the role of emotions in high‐stakes decision‐making within complex social environments.

Ever since [4], systems of spheres have been considered to give an intuitive and elegant way to give a semantics for logics of theory- or belief- change. Several authors [5, 11] have considered giving up the rather strong assumption that systems of spheres be linearly ordered by inclusion. These more general structures are called hypertheories after [8]. It is shown that none of the proposed logics induced by these weaker structures are compact and thus cannot be given a strongly complete (...) axiomatization in a finitary logic. Complete infinitary axiomatizations are given for several intuitive logics based on hypertheories that are not linearly ordered by inclusion. (shrink)

I develop a “two-systems” interpretation of Husserl’s theory of belief. On this interpretation, Husserl accounts for our sense of the world in terms of (1) a system of embodied horizon meanings and passive synthesis, which is involved in any experience of an object, and (2) a system of active synthesis and sedimentation, which comes on line when we attend to an object’s properties. I use this account to defend Husserl against several forms of Heideggerean critique. One line of (...) critique, recently elaborated by Taylor Carman, says that Husserl wrongly loads everyday perception with explicit beliefs about things. A second, earlier line of critique, due to Hubert Dreyfus, charges Husserl with thinking of belief on a problematic Artificial Intelligence (AI) model which involves explicit rules applied to discrete symbol structures. I argue that these criticisms are based on a conflation of Husserl’s two systems of belief. The conception of Husserlian phenomenology which emerges is compatible with Heideggerean phenomenology and associated approaches to cognitive science (in particular, dynamical systems theory).

The following article discovers current trends of contemporary epistemology, related to epistemic agent and his/her activities. A number of issues raised here describe internal experience of the agent, such as (in)voluntary nature of belief formation, trust in one’s faculties of perception, correspondence of formed beliefs to evidence, demarcation between purely epistemic and pragmatic rationality. Another part of the issues is related to external experiences of the agent. The most crucial among them are: blameworthiness of the agent’s belief system, (...) limited intake of testimonial knowledge as a result of social bias; epistemic disagreement and “epistemic peers” as the sources of knowledge or additional pressure from the environment. The author considers virtue epistemology as a new way of performing normativity. (shrink)

Challenges all forms of fundamentalism and unexamined belief systems from a philosophical and sceptical viewpoint. Is unquestioning belief making a global comeback? The growth of religious fundamentalism seems to suggest so. For the sceptically minded, this is a deeply worrying trend, not just confined to religion. Political, economic, and scientific theories can demand the same unquestioning obedience from the general public. Stuart Sim outlines the history of scepticism in both the Western and Islamic cultural traditions, and from the Enlightenment to (...) postmodernism. Setting out what a sceptical politics might be like, Empires of Belief argues that we need less belief and more doubt: an engaged scepticism to replace the pervasive dogmatism that threatens our democracies.

In this paper we explore the relationship between norms of belief revision that may be adopted by members of a community and the resulting dynamic properties of the distribution of beliefs across that community. We show that at a qualitative level many aspects of social belief change can be obtained from a very simple model, which we call ‘threshold influence’. In particular, we focus on the question of what makes the beliefs of a community stable under various dynamical (...) situations. We also consider refinements and alternatives to the ‘threshold’ model, the most significant of which is to consider changes to plausibility judgements rather than mere beliefs. We show first that some such change is mandated by difficult problems with belief-based dynamics related to the need to decide on an order in which different beliefs are considered. Secondly, we show that the resulting plausibility-based account results in a deterministic dynamical system that is non-deterministic at the level of beliefs. (shrink)

The present paper aims at a synthesis of belief revision theory with the Sneed formalism known as the structuralist theory of science. This synthesis is brought about by a dynamisation of classical structuralism, with an abductive inference rule and base generated revisions in the style of Rott (2001). The formalism of prioritised default logic (PDL) serves as the medium of the synthesis. Why seek to integrate the Sneed formalism into belief revision theory? With the hybrid system of the present (...) investigation, a substantial simplification of the ranking information that is necessary to define revisions and contractions uniquely is achieved. This system is, furthermore, expressive enough to capture complex and non-trivial scientific examples. It is thus closely related to a novel research area within belief revision theory which addresses the dynamics of scientific knowledge. (shrink)

I argue that the constitutive aim of belief and the constitutive aim of science are both knowledge. The ‘aim of belief’, understood as the correctness conditions of belief, is to be identified with the product of properly functioning cognitive systems. Science is an institution that is the social functional analogue of a cognitive system, and its aim is the same as that of belief. In both cases it is knowledge rather than true belief that is the product of proper (...) functioning. (shrink)

Addiction is almost universally held to be characterized by a loss of control over drug-seeking and consuming behavior. But the actions of addicts, even of those who seem to want to abstain from drugs, seem to be guided by reasons. In this paper, I argue that we can explain this fact, consistent with continuing to maintain that addiction involves a loss of control, by understanding addiction as involving an oscillation between conflicting judgments. I argue that the dysfunction of the mesolimbic (...) dopamine system that typifies addictions causes the generation of a mismatch between the top-down model of the world that reflects the judgment that the addict ought to refrain from drugs, and bottom-up input caused by cues predictive of drug availability. This constitutes a powerful pressure toward revising the judgment and thereby attenuating the prediction error. But the new model is not stable, and shifts under the pressure of bottom-up inputs in different contexts; hence the oscillation of all-things-considered judgment. Evidence from social psychology is adduced, to suggest that a similar process may be involved in ordinary cases of weakness of will. (shrink)

In the first Critique, Kant famously holds a novel practical notion of Belief (Glauben) as assent justified not by evidence but by practical considerations. This paper examines the early development of Kant’s practical notion of Belief prior to the first Critique. It aims to make clear what prompted Kant to develop this notion in the first place, and how this notion came to assume its crucial role in Kant’s critical system. This development, I argue, has two main steps. The (...) first is his introduction of a practical notion of Belief in mid-to-late 1760s. I argue that he did so because he regards this notion as a useful tool to get ordinary people to justifiably commit to the existence of God and an after-life. The second step is Kant’s abandonment of the objective validity of his logical proof of God around 1772. This step elevated Belief from a merely useful means to the only justified way to commit to the existence of God and an after-life. This second step, I argue, is closely connected to Kant’s pivot to the view that the objective validity of concepts requires sensibly given objects, and it is motivated by Kant’s concern with subject-cancelling real repugnance.

Different religious traditions offer apparently very different pictures of the world. How are we to make sense of this radical diversity of religious belief? In this book, Professor Godlove argues that religions are alternative conceptual frameworks, the categories of which organise experience in diverse ways. He traces the history of this idea from Kant to Durkheim, and then proceeds to discuss two constraints on the diversity of all human judgment and belief: first that human experience is made possible by shared, (...) a priori rules, and second, that as language-users we must presuppose that we hold the vast bulk of our beliefs in common. Given these unavoidable constraints, it is clear how religions may offer encompassing symbolic systems that often diverge dramatically from one another.

The puzzle of belief arises as currently no definition captures the various ways in which people believe. As a solution to this puzzle and to make the study of belief empirically tractable, Van Leeuwen and Lombrozo suggest acknowledging the plurality of beliefs and organizing beliefs according to their shared functions and traits. However, their proposal does not make yet the distinction between proper and derived functions of belief‐generating cognitive systems. For that, we need a theoretical perspective anchored in (...) evolutionary thinking. Such a perspective allows us to recognize the adaptive problems belief‐generating cognitive systems solve and what sorts of beliefs they will tend to produce. By analyzing beliefs based on evolutionary considerations, we not only make the puzzle of belief empirically tractable, but also take an important step toward solving it. (shrink)

Even if Peirce were well understood and there existed· general agreement among Peirce scholars on what he meant by his semiotics, or philosophy of signs, the undertaking of this book-wliich intends to establish a theoretical foundation for a new approach to understanding the interrelations of law, economics, and politics against referent systems of value-would be a risky venture. But since such general agreement on Peirce's work is lacking, one's sense of adventure in ideas requires further qualification. Indeed, the proverbial nerve (...) for failure must in any case be attendant. If one succeeds, one has introduced for further inquiry the strong possibility that should our social systems of law, economics, and politics---our means of interpersonal transaction as a whole-be understood against the theoretical back ground of a dynamic, "motion-picture" universe that is continually becoming, that is infinitely developing and changing in response to genuinely novel elements that emerge as existents, then the basic concepts of rights, resources, and reality take on new dimensions of meaning in correspondence with n-dimensional, infinite value judgments or truth-like beliefs which one holds. If such a view, as Peirce maintained, were possible and tenable not only for philosophy but as the basis for action and interaction in the world of human experience and practical affairs, one would readily say that risk taking is a small price for the realization of such possibility.

We consider extending the modal logic KD45, commonly taken as the baseline system for belief, with propositional quantifiers that can be used to formalize natural language sentences such as “everything I believe is true” or “there is something that I neither believe nor disbelieve.” Our main results are axiomatizations of the logics with propositional quantifiers of natural classes of complete Boolean algebras with an operator validating KD45. Among them is the class of complete, atomic, and completely multiplicative BAOs validating (...) KD45. Hence, by duality, we also cover the usual method of adding propositional quantifiers to normal modal logics by considering their classes of Kripke frames. In addition, we obtain decidability for all the concrete logics we discuss. (shrink)

This paper offers a new model of belief by embedding the Peircean account of belief into a formal dialogue system that uses argumentation schemes for practical reasoning and abductive reasoning. A belief is characterised as a stable proposition that is derived abductively by one agent in a dialogue from the commitment set (including commitments derived from actions and goals) of another agent. On the model (to give a rough summary), a belief is defined as a proposition held by an (...) agent that (1) is not easily changed (stable), (2) is a matter of degree (held more or less weakly or strongly), (3) guides the goals and actions of the agent, and (4) is habitually or tenaciously held in a manner that indicates a strong commitment to defend it. It is argued that the new model overcomes the pervasive conflict in artificial intelligence between the belief-desire-intention model of reasoning and the commitment model. (shrink)
