Epistemological Theories

I argue against the Standard View of ignorance, according to which ignorance is defined as equivalent to lack of knowledge, that cases of environmental epistemic luck, though entailing lack of knowledge, do not necessarily entail ignorance. In support of my argument, I contend that in cases of environmental luck an agent retains what I call epistemic access to the relevant fact by successfully exercising her epistemic agency and that ignorance and non-ignorance, contrary to what the Standard View predicts, are not (...) modal in the sense that knowledge is. After responding to objections, I conclude by sketching an alternative account of ignorance centered on the notions of epistemic access and epistemic agency. (shrink)

Daniel Greco (forthcoming) argues that there cannot be epistemic dilemmas. I argue that he is wrong.

Der Beitrag beleuchtet die Struktur und Funktion forschender Laborpraxis vor dem Hintergrund verschiedener erkenntnis- und wissenschaftstheoretischer Positionen. Das Labor kann in seiner Relevanz unterschätzt werden – mit Blick auf die darin verrichteten praktischen Tätigkeiten, auf dabei erforderliche Urteilsbildungen und nicht zuletzt auf unverzichtbare Impulse für die Wissenschaft. Die abstrakte Gegenüberstellung von Theorie und Praxis ist aufzugeben. Zugleich sollte Wissenschaft weder allein über das Labor noch über die Theoriebildung bestimmt werden. Abschließend plädiert der Beitrag dafür, die skizzierten Fragestellungen in die Labordidaktik (...) sowie in die Planung und Durchführung von Lernlaboren einzubeziehen. (shrink)

Essential for the concept of the law of nature is not only spatio-temporal universality, but also functionality in the sense of the dependency on physical conditions of natural entities. In the following it is explained in detail that just the neglect of this functional property is to be understood as the real reason for the occurrence of the Goodman paradox. As a consequence, the behavior of things seems to be completely at the mercy of the temporal change of unique absolute (...) temporal points. It is exactly this (mis-)understanding that also generated the induction problem. From the intrinsic connection between universality and functionality, however, - that is my claim - the ontological consequence of a nature results, for which the potentiality of lawfulness is coupled to essentially functionally defined time sequences.

Modalists think that knowledge requires forming your belief in a “modally stable” way: using a method that wouldn't easily go wrong (i.e. safety), or using a method that wouldn't have given you this belief had it been false (i.e. sensitivity). Recent Modalist projects from Justin Clarke-Doane and Dan Baras defend a principle they call “Modal Security,” roughly: if evidence undermines your belief, then it must give you a reason to doubt the safety or sensitivity of your belief. Another recent Modalist (...) project from Carlotta Pavese and Bob Beddor defends “Modal Virtue Epistemology”: knowledge is a belief that is maximally modally robust across “normal” worlds. We'll offer new objections to these recent Modalist projects. We will then argue for a rival view, Explanationism: knowing something is believing it because it's true. We will show how Explanationism offers a better account of undermining defeaters than Modalism, and a better account of knowledge. (shrink)

This paper compares epistemic virtue from the viewpoints of Zagzebski and Mulla Sadra, aiming to determine the extent to which their viewpoints on epistemic virtue are similar. Zagzebski, the contemporary philosopher, considers epistemic virtue as the basis on which knowledge is interpreted. She sees epistemic virtue as a requirement for achieving knowledge. Mulla Sadra, the founder of Transcendent Philosophy, considers knowledge as an outcome of intellectual virtues without which there would be no knowledge. The role these two philosophers ascribe to (...) moral and intellectual virtues and vices in forming the identity makes it possible to compare their interpretation of epistemic virtues. As a virtue responsibilist, Zagzebski sees epistemic virtue as a character trait and explains its nature by its different components. Sadra as well, sees epistemic virtue as a character trait. Evidence shows that Sadra’s definition of intellectual virtues is similar to that given by Zagzebski in many respects. Examining Zagzebski’s viewpoint on epistemic virtue, this paper will discuss Sadra’s viewpoint on epistemic virtue as well as its contribution to knowledge. In conclusion the similarities of the two viewpoints will be delineated. (shrink)

This article compares and contrasts the reception of Comte’s positivism in the works of William Whewell, John Stuart Mill and Franz Brentano. It is argued that Whewell’s rejection of positivism derives from his endorsement of a constructivist account of the inductive sciences, while Mill and Brentano’s sympathies for positivism are connected to their endorsement of an empiricist account. The mandate of the article is to spell out the chief differences between these two rival accounts. In the last, conclusive section, Whewell’s (...) anti-positivist argument is briefly assessed, and rebutted. (shrink)

According to a common conception of legal proof, satisfying a legal burden requires establishing a claim to a numerical threshold. Beyond reasonable doubt, for example, is often glossed as 90% or 95% likelihood given the evidence. Preponderance of evidence is interpreted as meaning at least 50% likelihood given the evidence. In light of problems with the common conception, I propose a new ‘relevant alternatives’ framework for legal standards of proof. Relevant alternative accounts of knowledge state that a person knows a (...) proposition when their evidence rules out all relevant error possibilities. I adapt this framework to model three legal standards of proof—the preponderance of evidence, clear and convincing evidence, and beyond reasonable doubt standards. I describe virtues of this framework. I argue that, by eschewing numerical thresholds, the relevant alternatives framework avoids problems inherent to rival models. I conclude by articulating aspects of legal normativity and practice illuminated by the relevant alternatives framework. (shrink)

This work has as its main goal to discuss two different epistemic proposals, both under the reliabilist handle. The first one, developed by Alvin Goldman, has as its central goal to offer an adequate characterization of the justificational element present in the standard account of knowledge. Goldman's proposal has the initial challenge of properly explaining Gettier's demand presented some years earlier, but also to correct some more central problems that affect his own causal theory of knowledge. However, the externalist proposal (...) within Goldman's reliabilism faced some serious attacks directed to its notion of justification. Three of these attacks became well known in the recent literature: the generality problem, the meta-incoherence problem and the new evil genius problem. Each one in its own way has established challenges to the his reliabilist account. The second reliabilist theory we will discuss consists in a reformulation of Goldman's account, defended mainly by Ernest Sosa in a series of very important works in contemporary epistemology. In these works, Sosa was able to insert the notion of intellectual virtues in the epistemological debate, bringing to the center of the externalist debate an idea of a responsible belief formation, and at the same time trying to give a proper answer to the more central challenges faced by original reliabilism. In the first part of the paper I present the first of these theories, and after that I offer a treatment of Sosa's reformulation of reliabilism and a defense of this proposal as a more adequate theory to deal with some basic demands of a proper theory of justification.

On an evidentialist position, it is epistemically rational for us to believe propositions that are (stably) supported by our total evidence. We are epistemically permitted to believe such propositions, and perhaps even ought to do so. Epistemic rationality is normative. One popular way to explain the normativity appeals to epistemic teleology. The primary aim of this paper is to argue that appeals to epistemic teleology do not support that we ought to believe what is rational to believe, only that we (...) are permitted to do so. In arguing for that, I defend an epistemic teleological position that is radical in nature. It involves no commitment to aiming at the truth. I conclude by dispelling some worries that have been raised about my position. (shrink)

Despite playing an important role in epistemology, philosophy of science, and more recently in moral philosophy and aesthetics, the nature of understanding is still much contested. One attractive framework attempts to reduce understanding to other familiar epistemic states. This paper explores and develops a methodology for testing such reductionist theories before offering a counterexample to a recently defended variant on which understanding reduces to what an agent knows.

This work aims to present and discuss recent developments in epistemology that seek for satisfactory formulations and responses to the problem of radical skepticism. Its main goal is to understand how the skeptical problem can be properly characterized, how it can be viewed as inserted in the traditional dispute in epistemology between externalism and internalism, and to which extent antiskeptical theories are situated within this dispute. After identifying their place in the dispute, another antiskeptical proposal is discussed, one that suggests (...) a conciliatory take on the internalist/externalist debate. The way Duncan Pritchard presents this conciliatory view, known as epistemological disjunctivism, intends to show that we can know the things that radical skepticism wants to preclude us to know. In order to do that, we just have to consider our structure of reasons as one that allows us to have factive reasons, reasons of externalist and internalist nature, that could put us in a privileged position to know the things we ordinarily believe. After the presentation and discussion of Pritchard's epistemological disjunctivism, and his general rejection of skepticism, it is suggested that its antiskeptical tools are also available to more traditional epistemic theories - but to access them, some epistemological assumptions need to be adjusted. In order to do that, an alternative take on the internalism/externalism dispute is offered, so it can allow for a different way of conceiving the conciliatory antiskeptical strategy, one that has epistemic reliabilism as its framework. The final propposal consists in an attempt to democratize the disjunctivist tool against radical skepticism. (shrink)

In this paper, I present two ways of conceiving a genealogical explanation of the concept of knowledge. The first one is through the epistemic state of nature hypothesis developed by Edward Craig, according to which knowledge is understood as a concept evolved from the concept of a good informant. After considering Craig’s project, I draw a parallel between this approach and Miranda Fricker’s value-laden account of the same concept. Then, I present and discuss Fricker’s social take on Craig’s genealogy, in (...) which she suggests that the notions of a good informant and of knowledge are necessarily dependent on the establishment of a credibility norm, and that this norm should be viewed as inherently political. Lastly, I defend an illustration, through Kristie Dotson’s work, of how both genealogical approaches could explain and offer solutions to failings in the normativity of our epistemic systems.

In this article I challenge the positivist view that ethical statements are merely an expression of our emotions or preferences. I consider a moral statement, “Killing innocent civilians is wrong,” and argue that such a statement is a truthful moral norm. I show that what is fundamental to agreement in the realm of both facts and morals is a commonly shared attitude that determines human relatedness to the world. Scientific knowledge is a partial knowledge based on indifference, the state of (...) mind that constitutes scientific attitude. However, knowledge in morals does not presuppose indifference, but love. Once we accept that our thoughts and feelings are not incommunicable, we can arrive at inter-subjective and non-objective moral knowledge which results from our recognition of others as persons and our affective engagement with the world.

According to proper functionalist theories of warrant, a belief is warranted only if it is formed by cognitive faculties that are properly functioning according to a good, truth-aimed design plan, one that is often thought to be specified either by intentional design or by natural selection. A formidable challenge to proper functionalist theories is the Swampman objection, according to which there are scenarios involving creatures who have warranted beliefs but whose cognitive faculties are not properly functioning, or are poorly designed, (...) or are not aimed at truth. In this paper, we draw lessons from cognitive science in order to develop a novel argument for the conclusion that the Swampman objection fails against proper functionalist theories of warrant. Our argument not only shows that the underlying, central intuition motivating Swampman-like scenarios is false but also motivates proper function as a necessary condition for warrant, thereby lending support to the claim that any theory of knowledge that lacks a proper function requirement is false.

Sektion Erkenntnistheorie, 29.09.2014, XXIII. Kongress der Deutschen Gesellschaft für Philosophie 2014 in Münster. -/- The problem of synthetic judgments touches upon the question whether philosophy is in fact capable of making independent truth statements. According to Kant, synthetic judgments formulate the conditions for the possibility of objectively valid knowledge a priori. As far as empirical attempts at reinterpretation of the aprioristic fall short of this ambition, Kant’s a priori goes deeper. This is because modern science strives towards objective knowledge, although (...) its statements are fundamentally fallible. The topic of synthetic a priori thus continues to be relevant. -/- This paper will show that, in order to be viable at all, a modernized version of transcendental philosophy must ‘depart from’ the concepts of “independence from empirics” and/or the “purity” of the aprioristic. Kant’s reflections on non-pure synthetic a priori knowledge already contain attempts at this. Furthermore, the aprioristic validity of knowledge does not exclude the possibility, that it can be discovered empirically. Fries and, subsequently, Nelson proceeded with this separation (initially ascribed to Reichenbach) between the contexts of validity and discovery of knowledge, pointing out that the a priori can indeed be discovered empirically, yet never be proven. -/- Currently, there are still a number of valid reasons for arguing that concepts from transcendental philosophy continue to be of fundamental importance for the modern sciences. However, it must not be neglected that, even within a modernized framework of transcendental philosophy various unsolved problems remain and/or are created (such as the unfeasibility of the aprioristic claim to general validity and necessity, the problem of drawing a clear boundary between the noumenal and phenomenal worlds). Moreover, the “beautiful structure” of the Kantian system, which constitutes much of its persuasive strength, is lost. (shrink)

Arguments pro and contra convergent realism - underdetermination of theory by observational evidence and pessimistic meta-induction from past falsity- are considered. It is argued that, to meet the counter-arguments challenge, convergent realism should be considerably changed with a help of modification of the propositions from this meta-programme’s “hard core” and “protecting belt”. Maybe one of the ways out is to turn to the coherent theory of truth. Some of the works of Hegel (as interpreted by Merab Mamardashvili and Alexandre Kojev), (...) Husserl and Heidegger can help to dig still deeper into the background of this theory. Key words: Husserl, Heidegger, Hegel, convergent realism, internal realism, coherent theory of truth. -/- .

Aquinas’s process of abstraction of the particular thing into a universal concept is of pivotal importance for grounding his philosophy and theology in a natural framework. Much has been said and written regarding Aquinas’s doctrine of abstraction, yet recent studies still consider it to be ‘nothing more than a kind of magic.’ This problematic claim is not without foundation, for in trying to understand exactly how this process works, we are constantly faced with an unbridgeable abyss and the repeated vague (...) explanations made by Aquinas. The plain truth is that Aquinas explains what abstraction ought to do and yet, most of the time, he does not explain how it is to be done. This paper intends to show that although Aquinas does not present us with a mechanism for the theory of abstraction, we are nevertheless able to construct a viable mechanism which accords with Aquinas’s guidelines. The aim of constructing a working mechanism that corresponds to what Aquinas demands of the process of abstraction is twofold: First, it attempts to extricate Aquinas’s doctrine of abstraction from the claims of being a quasi-natural doctrine. Second, a viable process of abstraction which is derived from Aquinian-Aristotelian sources can approach contemporary cognitive problems from a fresh point of view. (shrink)

This dissertation engages in a critical analysis of the work of Adolf Reinach in the theory of knowledge and legal philosophy. Reinach had trained as a lawyer and brought that perspective and experience to bear in his phenomenological work on problems in evidence and legal philosophy. His contributions to phenomenology in the early 20th century provide a window into the earliest phases of the development of the phenomenological movement, prior to World War I. This dissertation locates this work in the (...) European intellectual context of the era and finds analogies with key philosophical dilemmas and developments in England during the same period, arguably ones with shared intellectual roots. Valued for his talent as an inspiring university lecturer, Reinach was a central figure in the circle of young scholars who practiced phenomenology in the spirit of the "early" "pre-Ideen" phase of phenomenology. The dissertation Appendices include translations of selected excerpts from the Nachlass. My translation of the obituary Edmund Husserl wrote and published following Adolf Reinach's death in WWI is published separately. Professor Raymond Klibansky was my supervisor and mentor throughout.

In previous work, I have sought to show that the basic argument for epistemic relativism derives from the problem of the criterion that stems from ancient Pyrrhonian scepticism. Because epistemic relativism depends upon a sceptical strategy, it is possible to respond to relativism on the basis of an anti-sceptical strategy. I argue that the particularist response to scepticism proposed by Roderick Chisholm may be combined with a naturalistic and reliabilist conception of epistemic warrant as the basis for a satisfactory response (...) to epistemic relativism. In this paper, I outline this particularist response to relativism, and provide further commentary on the relationship between naturalism and particularism. In addition, I set the approach in contrast with reflective equilibrium approaches in epistemology. I also briefly explore the connection between the particularist response to relativism and G. E. Moore’s defense of an external world. (shrink)

Quine, criticism of Quine's Naturalized Epistemology.

During the seventeenth century the major cognitive faculties--sense, imagination, memory, and understanding or intellect--became the central focus of argument in metaphysics and epistemology to an extent not seen before. The theory of the intellect, long an important auxiliary to metaphysics, became the focus of metaphysical dispute, especially over the scope and powers of the intellect and the existence of a `pure' intellect. Rationalist metaphysicians such as Descartes, Spinoza, and Malebranche claimed that intellectual knowledge, gained independently of the senses, provides the (...) framework for constructing a new theory of nature. Other writers, including Hobbes and the early Gassendi, denied the existence of a distinct intellectual faculty, and so challenged the metaphysicians' abilities directly to perceive the essences of substances. The theory of the senses, which had long been a part of philosophical discussion, took on a new urgency, for adherents of the new corpuscularian philosophy needed to replace the dominant Aristotelian theory of real sensory qualities and sensible species. The revival of skepticism and a renewed interest in method also brought the faculties into prominence, for skeptical challenges typically were directed toward the faculties of sense and understanding, and the theory of method was conceived as providing instructions for the proper use of one's cognitive equipment. The theory of the faculties, then, is an important key to theories of knowledge in the seventeenth century. Indeed, rather than speaking of seventeenth century epistemology, it would be less anachronistic and more informative to speak of theories of cognition. The familiar (and over-stated) point that epistemology became fundamental to metaphysics during that century can then be restated as the point that the theory of faculties became central in metaphysical dispute.

From what said, then, it will be possible (...) to outline further elementary epistemological considerations. (shrink)

Meine Rekonstruktion von HeImholtz' Begründung der Energieerhaltung beabsichtigt, vor allem das Verhältnis von empirischen und nichtempirischen Elementen aufzuklären. Als erstes möchte ich zeigen, worin die nichtempirischen Elemente bestehen und dass Helmholtz bereits in der Einleitung, wo der selbständige Energiebegriff noch nicht entwickelt ist, an entscheidenden Stellen auf die wissenschaftliche Erfahrung Bezug nimmt. Im Gegensatz zur Transzendentalphilosophie macht Helmholtz die Geltungsbedingungen seines Mechanismus von zukünftigen empirischen Ergebnissen der Wissenschaft abhängig. Er gibt seinem Mechanismus in diesem Zusammenhang eine hypothetische Geltung, an deren (...) bloß vorübergehenden Charakter er aber bemerkenswerterweise keinen Zweifel hegt. (1.) Im zweiten Teil gehe ich der Frage nach, in welchem Maß die mit großer Siegesgewissheit vorgetragene mechanistische Begründung in die Formulierungen des Erhaltungssatzes Eingang findet. Helmholtz verwendet mehrere Energiebegriffe. Haben diese insgesamt oder nur teilweise einen von speziellen naturphilosophischen Annahmen unabhängigen Status? Auf welche Teile der Schrift hätte sich ein Wissenschaftler im vergangenen Jahrhundert stützen können, weIcher von der Energieerhaltung, nicht aber von Helrnholtz' Mechanismus überzeugt gewesen wäre?

In What is Philosophy?, Deleuze and Guattari define philosophy, famously, as an activity that consists in forming, inventing, and fabricating concepts.” But this definition of philosophy implies a somewhat singular “analytic of the concept,” to borrow Kant’s phrase. One of the problems it poses is the fact that concepts, from a Deleuzian perspective, have no identity but only a becoming. This paper examines the nature of this problem, arguing that the aim of Deleuze analytic is to introduce the form of (...) time into concepts in terms of what he calls “continuous variation” or “pure variability.” The aim is not to rediscover the eternal or the universal, but to find the conditions under which something new is produced (creativeness).

Knowledge is not only true belief, because some true beliefs are supported by lucky guesswork and hence do not describe knowledge. Knowledge requires possession of good reasons that elevates a true belief to the status of knowledge. This is justification condition. However, this concept of knowledge has been disputed by Gettier and requires modification. Some philosophers say that we must add the condition that the complete justification that a man has for what he believes must not depend on any false (...) sentence. In this paper, I will examines two theories of justification in detail, and 9 refer briefly to two theories. A simple concept of epistemic justification is that a person is justified in believing that (p), if his belief that (p) is based on adequate grounds. The first theory is the foundations theory, or foundationalism, according to it, knowledge and justification are based on some sort of foundation. Such foundation consists of basic beliefs that are justified in themselves, upon which the justification for all other beliefs rests. The second theory is the coherence theory, or coherentism. This theory is based on the thesis that belief is justified if it belongs to a coherent set of beliefs. Coherentists deny the need for basic beliefs because all beliefs may be justified by their relation to others by mutual support. The third theory is the externalist theory. The externalist says that we need neither basic beliefs nor coherence to acquire knowledge, but rather right kind of external relationship to get knowledge. According to Goldman the appropriate relationship is causal. Armstrong and Dretske have argued that the relationship results from some law of nature. The fourth theory is foundherentism. This theory is presented by Susan Haack as an alternative to foundationalism and coherentism. It agrees with coherentism that there are no basic beliefs and agrees with foundationalism that experience can be relevant to empirical justification. ليست المعرفة اعتقاداً صادقاً فحسب، لأن بعض الاعتقادات الصادقة يتم تأييدها عن طريق التخمين، ولذلك لا توصف بأنها معرفة. فالمعرفة تتطلب امتلاك الأسباب الجيدة التي ترفع الاعتقاد الصادق إلى مرتبة المعرفة، وهذا هو شرط التسويغ. ومع ذلك فقد جادل جيتير في هذا التصور للمعرفة وطالب بتعديله. وقال بعض الفلاسفة لابد من أن نضيف شرطا مؤداه أن التسويغ الكامل الذي يملكه الإنسان لما يعتقده يجب ألا يعتمد على أية جملة كاذبة. وفي هذا البحث سوف أفحص نظريتين في التسويغ بشيء من التفصيل، وأشير بإيجاز إلى نظريتين. والتصور البسيط للتسويغ المعرفي هو أن الشخص يكون مسوغا في الاعتقاد بأن (ق) إذا كان اعتقاده بأن (ق) قائم على أسس كافية. والنظرية الأولى هي نظرية الأسس أو نزعة الأسس، وتبعا لهذه النظرية فإن المعرفة والتسويغ يقومان على نوع ما من الأساس. ويتألف هذا الأساس من اعتقادات أساسية تكون مسوغة في ذاتها، ويرتكز عليها تسويغ جميع الاعتقادات الأخرى. والنظرية الثانية هي نظرية الاتساق أو نزعة الاتساق. وتقوم هذه النظرية على الدعوى القائلة إن الاعتقاد يكون مسوغا إذا كان ينتمي إلى مجموعة متسقة من الاعتقادات. وينكر أصحاب نظرية الاتساق الحاجة إلى اعتقادات أساسية لأن جميع الاعتقادات يجوز تسويغها عن طريق علاقتها باعتقادات أخرى بواسطة التأييد المتبادل. أما النظرية الثالثة فهي النظرية الخارجية. ويقول صاحب النظرية الخارجية إننا لا نحتاج إلى اعتقادات أساسية ولا إلى اتساق لكي نحصل على المعرفة، وإنما نحتاج بالأحرى إلى النوع الصحيح من العلاقة الخارجية بين الاعتقادات والواقع للحصول على المعرفة. وتبعا لجولدمان فإن العلاقة الملائمة هي علاقة سببية. أما ارمسترونج ودرتسكي فقد حاولا البرهنة على أن العلاقة تنشأ من قانون ما في الطبيعة. والنظرية الرابعة هي نزعة بين الأسس والاتساق. وتقدم سوزان هاك هذه النظرية بديلاً لنزعة الأسس ونزعة الاتساق. وتتفق نظريتها مع نزعة الاتساق على أنه لا توجد اعتقادات أساسية، وتتفق مع نزعة الأسس على أن التجربة يمكن أن تكون ملائمة للتسويغ التجريبي.

It is a widespread intuition that the coherence of independent reports provides a powerful reason to believe that the reports are true. Formal results by Huemer (1997), Olsson (2002, 2005), and Bovens and Hartmann (2003) prove that, under certain conditions, coherence cannot increase the probability of the target claim. These formal results, known as ‘the impossibility theorems’ have been widely discussed in the literature. They are taken to have significant epistemic upshot. In particular, they are taken to show that reports (...) must first individually confirm the target claim before the coherence of multiple reports offers any positive confirmation. In this paper, I dispute this epistemic interpretation. The impossibility theorems are consistent with the idea that the coherence of independent reports provides a powerful reason to believe that the reports are true even if the reports do not individually confirm prior to coherence. Once we see that the formal discoveries do not have this implication, we can recover a model of coherence justification consistent with Bayesianism and these results. This paper, thus, seeks to turn the tide of the negative findings for coherence reasoning by defending coherence as a unique source of confirmation. (shrink)

The coherence of independent reports provides a strong reason to believe that the reports are true. This plausible claim has come under attack from recent results in Bayesian epistemology. Huemer (1997), Olsson (2002, 2005), and Bovens and Hartmann (2003) prove that, under certain probabilistic conditions, coherence cannot increase the probability of the target claim. These results are taken to demonstrate that epistemic coherentism is untenable. To date no one has investigated how these Bayesian results bear on different conceptions of coherence. (...) In this paper, I investigate these Bayesian results by using Paul Thagard’s ECHO model of explanatory coherence (Thagard (2000)). Thagard’s ECHO model provides a natural representation of the evidential significance of multiple independent reports. The ECHO model, in contrast to the Bayesian models, captures the power of coherence in a witness scenario. The conditions that Bayesian models found to be impossible, ECHO models naturally accommodate. This demonstrates that there are different formal tools for representing coherence. I close with a discussion of the differences between the Bayesian model and the ECHO model. (shrink)

Design plays an integral role in the functions of modern society. Yet the abstract process by which designers carry out their work is not obvious. The study of design thinking has grown in recent years into a major area of academic research, yet it presently lacks a clear theoretical basis; and as a discipline, its methodologies are disparate. Here, we outline and clarify the framework of the scholarly study of design thinking, introducing the major ideas and concepts upon which the (...) field is based. We then discuss in detail the various methodological issues of the field, and argue that, in its current state, the field of design thinking cannot sustain itself as an independent area of academic research. We suggest that design thinking may best be studied from a sociological or science, technology, and society (STS) studies perspective. (shrink)

In this paper I prove that holistic coherentism is logically equivalent to the conjunction of symmetry and quasi-transitivity of epistemic support and a condition on justified beliefs. On the way I defend Tom Stoneham from a criticism made by Darrell Rowbottom and prove a premiss of Stoneham’s argument to be an entailment of coherentism.

In recent epistemology many philosophers have adhered to a moderate foundationalism according to which some beliefs do not depend on other beliefs for their justification. Reliance on such ‘basic beliefs’ pervades both internalist and externalist theories of justification. In this article I argue that the phenomenon of perceptual learning – the fact that certain ‘expert’ observers are able to form more justified basic beliefs than novice observers – constitutes a challenge for moderate foundationalists. In order to accommodate perceptual learning cases, (...) the moderate foundationalist will have to characterize the ‘expertise’ of the expert observer in such a way that it cannot be had by novice observers and that it bestows justification on expert basic beliefs independently of any other justification had by the expert. I will argue that the accounts of expert basic beliefs currently present in the literature fail to meet this challenge, as they either result in a too liberal ascription of justification or fail to draw a clear distinction between expert basic beliefs and other spontaneously formed beliefs. Nevertheless, some guidelines for a future solution will be provided. (shrink)

Coherentism maintains that coherent beliefs are more likely to be true than incoherent beliefs, and that coherent evidence provides more confirmation of a hypothesis when the evidence is made coherent by the explanation provided by that hypothesis. Although probabilistic models of credence ought to be well-suited to justifying such claims, negative results from Bayesian epistemology have suggested otherwise. In this essay we argue that the connection between coherence and confirmation should be understood as a relation mediated by the causal relationships (...) among the evidence and a hypothesis, and we offer a framework for doing so by fitting together probabilistic models of coherence, confirmation, and causation. We show that the causal structure among the evidence and hypothesis is sometimes enough to determine whether the coherence of the evidence boosts confirmation of the hypothesis, makes no difference to it, or even reduces it. We also show that, ceteris paribus, it is not the coherence of the evidence that boosts confirmation, but rather the ratio of the coherence of the evidence to the coherence of the evidence conditional on a hypothesis.

We construct a probabilistic coherence measure for information sets which determines a partial coherence ordering. This measure is applied in constructing a criterion for expanding our beliefs in the face of new information. A number of idealizations are being made which can be relaxed by an appeal to Bayesian Networks.

Coherentists on epistemic justification claim that all justification is inferential, and that beliefs, when justified, get their justification together (not in isolation) as members of a coherent belief system. Some recent work in formal epistemology shows that “individual credibility” is needed for “witness agreement” to increase the probability of truth and generate a high probability of truth. It can seem that, from this result in formal epistemology, it follows that coherentist justification is not truth-conducive, that it is not the case (...) that, under the requisite conditions, coherentist justification increases the probability of truth and generates a high probability of truth. I argue that this does not follow. (shrink)

Davidson claims that nothing can count as a reason for a belief except another belief. This claim is challenged by McDowell, who holds that perceptual experiences can count as reasons for beliefs. I argue that McDowell fails to take account of a distinction between two different senses in which something can count as a reason for belief. While a non-doxastic experience can count as a reason for belief in one of the two senses, this is not the sense which is (...) presupposed in Davidson's claim. While I focus on McDowell's view, the argument generalizes to other views which take experiences as reasons for belief. (shrink)
