Coherentism

I present evidence for a systematic complexity-coherence tradeoff in cognition. I show how feasible strategies for increasing cognitive complexity along three dimensions come at the expense of a heightened vulnerability to incoherence. I discuss two normative implications of the complexity-coherence tradeoff: a novel challenge to coherence-based theories of bounded rationality and a new strategy for vindicating the rationality of seemingly irrational cognitions. I also discuss how the complexity-coherence tradeoff sharpens recent descriptive challenges to dual process theories of cognition.

This thesis is concerned with historiographic knowledge, with its form, presuppositions, and justification. In the articles that form its backbone I argue that historiographic knowledge often takes the form of causal narratives, and that hindsight is an essential epistemic asset in the forging of those narratives. The articles further argue that historiographic knowledge is best understood through informational epistemology and a coherentist understanding of epistemic justification. The process of justification of historiographic knowledge claims, however, is also an intersubjective process in (...) which different disciplinary practices play an essential role. -/- The extended introduction of this thesis has three goals that come out of the articles: 1) to elucidate the nature and characteristics of the philosophy of scientific historiography; 2) to argue for an empirical turn in the discipline; and 3) to probe the relationship between historiography and other ways to relate to the past, and with that, the relationship between the philosophy of historiography and the theory of history. On the first issue, I argue for a broadly naturalist understanding of the discipline, and I define its main task as the philosophical reconstruction and explication of the scientific practices of (Rankean) historiography along with their limits. The determination of the reach and limits of these scientific practices is a fundamentally empirical task though, thus the call for an empirical turn. Having established the nature of scientific historiography, I ask what role a rational and truthful relation to the past should play in our individual lives and for society as a whole. -/- The goal of chapter III is to delineate the relationship between (scientific) historiography and politics, and to defend the discipline against politicist usurpations. For these reasons, I talk about some basic agreement among historians concerning politics and the limits of its influence on their discipline, just as much as I identify the positive influence that politics can have on historiography. The nature and justification of historiographic method is apolitical though; anyone of any political persuasion has good reasons to use those methods, if they want to produce knowledge of the past. The chapter closes with reflections on the (political) limits of historiographic reason. (shrink)

I argue that dimensional analysis provides an answer to a skeptical challenge to the theory of model mediated measurement. The problem arises when considering the task of calibrating a novel measurement procedure, with greater range, to the results of a prior measurement procedure. The skeptical worry is that the agreement of the novel and prior measurement procedures in their shared range may only be apparent due to the emergence of systematic error in the exclusive range of the novel measurement procedure. (...) Alternatively: what if the two measurement procedures are not in fact measuring the same quantity? The theory of model mediated measurement can only say that we _assume_ that there is a common quantity. In contrast, I show that the satisfaction of dimensional homogeneity across the metrological extension is independent evidence for the so-called assumption. This is illustrated by the use of dimensional analysis in high pressure experiments. This results in an extension of the theory of model mediated measurement, in which a common quantity in metrological extension is no longer assumed, but hypothesized. (shrink)

Evidentialism is one of the most sensible claims of recent philosophy. Yet it is often joined with other theses about the structure of justification and the nature of experience that are dubious. In this paper, I argue that experience is not a basic source of evidence. I contend that for an experience to justify a belief, it must be independently plausible that the experience is reliable based on background information. The paper develops an account of plausibility and examines cases, including (...) differences in expertise, clairvoyance, and social perceptions, to illustrate how background knowledge is necessary for the justification of experiential beliefs. I consider challenges from Bergmann's distinction between learned and unlearned doxastic responses and Lyons's inferential reliabilism. I conclude that these challenges do not succeed; perceptual evidence requires a broader perspective that supports the reliability of the experiential evidence. (shrink)

In everyday life, we think of skepticism as the position of a stubborn person who has higher epistemic standards than others. Hence, the skeptic is someone who defends extravagant ideas. Some skeptics may deny that climate change is real, while others claim that the first moon landing did not take place. Contemporary philosophers think of skepticism in a different way. In their view, skepticism is the conclusion of a paradoxical argument about epistemic statuses like knowledge and reasons. A paradoxical argument (...) is a logically valid argument that, starting from seemingly plausible premises, reaches an absurd conclusion. We introduce two skeptical arguments. The regress argument purports to show that we lack reasons to believe any claim whatsoever because the search for those reasons inevitably leads to an infinite regress. The underdetermination argument seeks to prove that we lack reasons to believe that there are chairs, trees, other people, and so on; it supports that conclusion by citing skeptical hypotheses, including the idea that we might be dreaming (Descartes 1641) or the suggestion that we could be brains in a vat connected to a supercomputer that mimics the pattern of neural activity that would be produced if we were perceiving external objects (Putnam 1981).

According to metaphysical coherentism, grounding relations form an interconnected system in which things ground each other and nothing is ungrounded. This potentially viable view’s logical territory remains largely unexplored. In this paper, I describe that territory by articulating four varieties of metaphysical coherentism. I do not argue for any variety in particular. Rather, I aim to show that not all issues which might be raised against coherentism will be equally problematic for all the versions of that view, which features far (...) more nuance and diversity than is typically ascribed to it. (shrink)

The method of reflective equilibrium (MRE) is a method of justification popularized by John Rawls and further developed by Norman Daniels, Michael DePaul, Folke Tersman, and Catherine Z. Elgin, among others. The basic idea is that epistemic agents have justified beliefs if they have succeeded in forming their beliefs into a harmonious system of beliefs which they reflectively judge to be the most plausible. Despite the common reference to MRE as a method, its mechanisms or rules are typically expressed in (...) a metaphorical or simplified manner and are therefore criticized as too vague. Recent efforts to counter this criticism have been directed towards the attempt to provide formal explications of MRE. This paper aims to supplement these efforts by providing an informal working definition of MRE. This approach challenges the view that MRE can adequately be characterized only in the negative as a set of anti-essentialisms. I argue that epistemic agents follow MRE iff they follow four interconnected rules, which are concerned with a minimalistic form of foundationalism, a minimalistic form of fallibilism, a moderate form of holism, and a minimalistic form of rationality. In the critical spirit of MRE, the corresponding working definition is, of course, provisional and revisable. In general, the aim is to contribute to a reflective equilibrium (RE) concerning MRE. If it is successful, this working definition provides a better grasp of the most basic elements of the method and thereby enhances our understanding of it. (shrink)

What is the place of coherence, or structural rationality, in good first-personal deliberation? According to Kolodny (2005), considerations of coherence are irrelevant to good first-personal deliberation. When we deliberate, we should merely care about the reasons or evidence we have for our attitudes. So, considerations of coherence should not show up in deliberation. In response to this argument, Worsnip (2021) argues that considerations of coherence matter for how we structure deliberation. For him, we should treat incoherent combinations of attitudes as (...) off-limits in deliberation. Some important questions are left unanswered by both camps. What do we mean by considerations of coherence “showing up” in first-personal deliberation? How do we interpret the divide between reasons-responsiveness and coherence? How should we interpret cases in which considerations of coherence interact with other norms or requirements? In this paper, I show how Haack’s (1993) crossword puzzle analogy sheds light on these questions. Also, the crossword puzzle analogy allows us to evaluate Kolodny’s objection and identify promising avenues for future research. (shrink)

Structural requirements of rationality prohibit various things, like having inconsistent combinations of attitudes, having means-end incoherent combinations of attitudes, and so on. But what is the distinctive feature of structural requirements of rationality? And do we fall under an obligation to be structurally rational? These issues have been at the heart of significant debates over the past fifteen years. Some philosophers have recently argued that we can unify the structural requirements of rationality by analyzing what is constitutive of our attitudes (...) (Lee, 2020; Worsnip, 2018a). It has also been suggested that, in the course of good first-personal deliberation, agents should treat structurally irrational combinations of attitudes as off-limits (Worsnip, 2021). In this paper, I raise a worry for these two theses concerning structural rationality. Roughly, I argue that some imperfect epistemic agents (like us) can be disposed to have structurally irrational combinations of attitudes. Also, when these imperfect agents deliberate, they should not treat structurally irrational combinations of attitudes as off-limits. Given our imperfections, being structurally irrational can very well be the best option we have. More generally, these observations reveal that structural rationality should not always be theorized independently from more “substantive” norms, like responsiveness to reasons or expected value optimization.

In this new explanationist account of epistemic justification, Poston argues that the explanatory virtues provide all the materials necessary for a plausible account of justified belief. There are no purely autonomous reasons. Rather reasons occur only within an explanatory coherent set of beliefs.

Racial discrimination is a multidimensional concept. Yet, subjective measures of racial discrimination focus on particular dimensions (interpersonal over institutional, attributable over ambiguously attributable). I argue that there is path dependence in the development and validation of subjective measures, such that existing scales prevent the development of scales that are better for some purpose. Path dependence can occur when researchers: (1) adopt a coherentist view of measurement, namely, in iteratively refining constructs and measures and (2) employ current psychometric validation practices. The (...) main takeaway is that norms are needed to evaluate the initial refinement of the construct rather than taking it for granted. (shrink)

Recently, metaphysical coherentism has been propounded as an alternative to metaphysical foundationalism and infinitism. The view replaces the picture of reality as a hierarchy of levels with that of a network of objects or facts standing in symmetric or, more generally, cyclic relations of metaphysical dependence. This paper defends the orthodox picture of a well-founded hierarchy against the claimed superiority of coherentism. First, it will be argued that alleged theoretical advantages of coherentism do not hold up to scrutiny. Secondly, examples (...) that are claimed to support coherentism are either misdescribed as involving metaphysical interdependence, or foundationalist treatments fare at least as good and often better than coherentist interpretations. Thirdly, a similar diagnosis applies to a recently proposed coherentist interpretation of quantum entanglement. The more general diagnosis is that claims of metaphysical dependence are convincing only if there is a detailed account of how one item metaphysically explains another. While foundationalists can resort to various specific explanatory relations, coherentism seems to be incapable of providing detailed explanations. (shrink)

This paper develops an internal critique of Graham Oppy’s metaphilosophy of religion – his theories of argumentation, worldview comparison, and epistemic justification. First, it presents Oppy’s views and his main reasons in their favor. Second, it argues that Oppy is committed to two claims – that only truth-conducive reasons can justify philosophical belief and that such justification depends entirely on one’s judgments about the theoretical virtues of comprehensive worldviews – that jointly entail the unacceptable conclusion that philosophical beliefs cannot be (...) justified. Third, it briefly argues that of his two claims, it is his thoroughgoing coherentism that should be rejected. (shrink)

Alongside science and law, argumentation is also of central importance in everyday life. But what characterizes a good argument? This question has occupied philosophers and psychologists for centuries. The theory of Bayesian argumentation is particularly suitable for clarifying it, because it allows us to take into account in a natural way the role of uncertainty, which is central to much argumentation. Moreover, it offers the possibility of measuring the strength of an argument in probabilistic terms. One way to do this, (...) implicit in much work, is to identify the strength of an argument with the degree to which the premises of the argument confirm the conclusion. We criticize this prima facie plausible proposal and suggest instead that the strength of an argument has something to do with how much the premises and the conclusion of the argument cohere with each other. This leads to a new probabilistic measure whose properties we examine in more detail. (shrink)

In the latter half of the twentieth century, foundationalist approaches to epistemology and philosophy of science were widely rejected in favour of holist and coherentist approaches. Kuhn may be regarded as a contributor to this anti-foundationalist tendency. In this paper, I wish to consider the extent to which Kuhn’s epistemological thinking was coherentist in nature. This is a task that has already begun in the work of Jouni-Matti Kuukkanen. However, I wish to go beyond Kuukkanen by raising a number of (...) questions that he does not address. First, I present Kuukkanen’s coherentist interpretation of Kuhn. In the next section, I argue that the interpretation fails to show that Kuhn rejects non-doxastic justification in favour of coherence relations among beliefs. In the fourth section, I present a standard objection to coherentism that any adequate formulation of the doctrine must confront, the “input objection”. I then frame the objection in terms of Kuhn’s model. In the fifth section, I argue that Kuhn’s account of science is able to satisfactorily deal with the input objection. In the sixth section, I explore the relationship between Kuhn’s treatment of perception and the anti-foundationalist tendency that contributed to the rise of coherentism. (shrink)

In his paper, “Kuhn, Coherentism and Perception,” Howard Sankey shows that Kuhn’s epistemology does not fit squarely in the coherentist framework, though some aspects of his theory are akin to that position. Sankey examines and then criticizes a previous work by Jouni-Matti Kuukkanen that argues that Kuhn’s work fits in well with a coherentist approach and with a realistic position in which the correspondence theory of truth is still defensible. I will not examine Kuukkanen’s argument here. I will only comment (...) on Sankey’s qualifications on Kuhn’s alleged coherentism. In the first section I shall add some more details to Kuhn’s relation to the concept of “the given” that reinforce Sankey’s doubts concerning the thesis that the author of The Structure of Scientific Revolutions fits in with a coherentist account of scientific knowledge—though I also agree with Sankey (and Kuukannen) that a study of coherentist ingredients in Kuhn’s epistemology would bring insight. Even so, labeling Kuhn’s epistemological views as either foundationalist or coherentist goes beyond his original point of view. I shall devote the second section of this commentary to argue in favor of this thesis on the basis of an unpublished lecture by Kuhn in which he discusses his convictions in the theory of knowledge—which agree with his attack to convergent views of scientific progress —and their connection to Ludwig Wittgenstein’s On Certainty.

Despite wholeheartedly endorsing Lycan's commonsensism on display in On Evidence in Philosophy, this paper raises concerns about three views Lycan defends in that book. The first view is compatibilism about free will and determinism. The paper argues that Lycan's Moorean defense of compatibilism fails and that it is plausible for commonsensists to think that, in their dispute with incompatibilists, the burden of proof is on compatibilists. The second view is Lycan's Principle of Humility, offered as an account of the conditions (...) under which recognized disagreement undermines knowledge. The paper considers a permissive and a demanding way of understanding his Principle of Humility and suggests that, contra Lycan, commonsensism fits better with a permissive understanding. The third view discussed is his coherentism about justification. The paper concludes that commonsensism is best understood in foundationalist terms and that Lycan's coherentism is, in fact, an inadequately motivated version of foundationalism. (shrink)

According to Lehrer’s defeasibility account of knowledge, we can understand knowledge as undefeated justified true belief. But this account faces many serious problems. One important problem is that from one’s subjective point of view, one can hardly bridge the gap between one’s personal justification and objective truth. Another important problem is that this account can hardly accommodate the externalist intuition that the epistemic status of a belief is not entirely determined by factors that are internal to the subject’s perspective. The (...) goal of this paper is to offer an alternative account of knowledge which can successfully deal with these problems. On the basis of a Sellarsian social practice theory of justification, I argue that we can understand knowledge as objectively justified belief. (shrink)

Lawrence Bonjour supported coherentism in the early period, but turns to foundationalism in the later period. In this paper I shall focus on two sides in relation to his epistemology. To understand his early and later positions, first, I shall explain his coherentism and foundationalism. Second, I shall consider what objections have been raised to each position. Thus we can evaluate why Bonjour abandoned his coherentism and why his foundationalism succeeds as a plausible theory for empirical justification.

Perhaps the most fundamental question of epistemology asks on what grounds our knowledge of the world ultimately rests. The traditional Cartesian answer is that it rests on indubitable facts arrived at through rational insight or introspection. Coherentists reject this answer, claiming instead that knowledge arises from relations of coherence or mutual support: if our beliefs cohere, we can be sure that they are mostly true. The first part of this Element introduces the reader to the main ideas and problems of (...) coherentism. The next part describes the 'probabilistic turn', leading up to recent demonstrations that coherence fails to be conducive to truth. The final part reassesses the current debate about the proper definition of coherence from the standpoint of Rudolf Carnap's methodology of explication. The upshot is a tentative and qualified defence of one of the early coherence measures. (shrink)

I start by defining sentience and giving an analysis of the epistemological problems that plague its scientific study; this consists mainly in justifying that the attribution of sentience is underdetermined by the data. Second I show that as a result of this situation of underdetermination, most of the types of arguments used to infer sentience from the data are inconclusive and lead to a stalemate. Third, I argue that the stalemates arise from a foundationalist epistemology which needlessly leads to skeptical (...) conclusions; as an alternative, I propose to adopt a coherentist framework and defend a process of ‘epistemic iteration’ (Chang 2004) within that framework, which I argue gives us a way out of the underdetermination.

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 work in Bayesian epistemology. This work shows that, under certain probabilistic conditions, coherence cannot increase the probability of the target claim. These theorems are taken to demonstrate that epistemic coherentism is untenable. To date no one has investigated how these results bear on different conceptions of coherence. I investigate this situation using Thagard’s ECHO model of (...) explanatory coherence. Thagard’s ECHO model provides a natural representation of the evidential significance of multiple independent reports. (shrink)

Coherentists fail to distinguish between the individual revision of a conviction and the intersubjective revision of a rule. This paper fills this gap. A conviction is a norm that, according to an individual, ought to be ascribed to a provision. By contrast, a rule is a judicially ascribed norm that controls a case and is protected by the formal principles of competence, certainty, and equality. A revision of a rule is the invalidation or modification such a judicially ascribed norm, provided (...) that the judge meets the burden of argumentation of formal principles. Thus, judges can revise their convictions without changing the law. (shrink)

Being incoherent is often viewed as a paradigm kind of irrationality. Numerous authors attempt to explain the distinct-seeming failure of incoherence by positing a set of requirements of structural rationality. I argue that the notion of coherence that structural requirements are meant to capture is very slippery, and that intuitive judgments – in particular, a charge of a distinct, blatant kind of irrationality – are very imperfectly correlated with respecting the canon of structural requirements. I outline an alternative strategy for (...) explaining our patterns of normative disapproval, one appealing to feasible dispositions to conform to substantive, non-structural norms. A wide range of paradigmatic cases of incoherence, I will argue, involve manifesting problematic dispositions, dispositions that manifest across a range of cases as blatant-seeming normative failures. (shrink)

I argue that bounded agents face a systematic accuracy-coherence tradeoff in cognition. Agents must choose whether to structure their cognition in ways likely to promote coherence or accuracy. I illustrate the accuracy-coherence tradeoff by showing how it arises out of at least two component tradeoffs: a coherence-complexity tradeoff between coherence and cognitive complexity, and a coherence-variety tradeoff between coherence and strategic variety. These tradeoffs give rise to an accuracy-coherence tradeoff because privileging coherence over complexity or strategic variety often leads to (...) a corresponding reduction in accuracy. I conclude with a discussion of two normative consequences for the study of bounded rationality: the importance of procedural rationality and the role of coherence in theories of bounded rationality.

What is the primary intellectual aim of philosophy? The standard view is that philosophy aims to provide true answers to philosophical questions. But if our aim is to settle controversy by answering such questions, our discipline is an embarrassing failure. Moreover, taking philosophy to aim at providing true answers to these questions leads to a variety of puzzles: How do we account for philosophical expertise? How is philosophical progress possible? Why do job search committees not care about the truth or (...) falsity of a candidate’s philosophical views? We argue that philosophy does not aim at discovering true answers to philosophical questions. Instead, its primary intellectual aim is understanding. We argue that many familiar aspects of philosophy become intelligible once we accept this hypothesis. (shrink)

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, M. 1997. “Probability and Coherence Justification.” Southern Journal of Philosophy 35: 463–72, Olsson, E. 2002. “What is the Problem of Coherence and Truth?” Journal of Philosophy XCIX : 246–72, Olsson, E. 2005. Against Coherence: Truth, Probability, and Justification. Oxford University Press., Bovens, L., and S. Hartmann. 2003. Bayesian Epistemology. Oxford University Press, 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)

There are good reasons to endorse scientific realism and good reasons to endorse common-sense realism. However, it has sometimes been suggested that there is a tension between the two which makes it difficult to endorse both. Can the common-sense picture of the world be reconciled with the strikingly different picture presented to us by our best confirmed theories of science? This chapter critically examines proposals for doing so, and it offers a new one, which is essentially this. It is a (...) psychological fact that we have certain common-sense beliefs. In the framework of reductive physicalism, all beliefs, including the common-sense ones, are nothing but brain states and processes. Being scientifically realist about these brain states and accepting the reductive-physicalist view of the mind, we can account for the psychological fact that we have certain common-sense beliefs with certain contents, without committing to the idea that the contents of these common-sense beliefs have to be true of the world. In this coherentist approach we are not required to relinquish our common-sense beliefs, since although they are false according to science, this very same science shows that holding those beliefs is fully rational.

Wilfrid Sellars's "Empiricism and the Philosophy of Mind" begins with an argument against sense-datum epistemology. There is some question about the validity of this attack, stemming in part from the assumption that Sellars is concerned with epistemic foundationalism. This paper recontextualizes Sellars's argument in two ways: by showing how the argument of EPM relates to Sellars's 1940s work, which does not concern foundationalism at all; and by considering the view of H.H. Price, Sellars's teacher at Oxford and the only classical (...) datum theorist to receive substantive comment in EPM. Timm Triplett has claimed that Sellars's discussion simply begs the question against Price, but this depends on the mistaken assumption that Sellars's concern is with foundationalism. On the contrary, Sellars's argument concerns the assumption that the innate capacity for sensory experience counts as "thinking in presence" in the way needed for empiricist accounts of content acquisition. Price's distinction between noticing universals and being aware of them encapsulates the tensions empiricists face here. (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)

The paper takes off from the suggestion of Jouni-Matti Kuukkanen that Kuhn’s account of science may be understood in coherentist terms. There are coherentist themes in Kuhn’s philosophy of science. But one crucial element is lacking. Kuhn does not deny the existence of basic beliefs which have a non-doxastic source of justification. Nor does he assert that epistemic justification only derives from inferential relationships between non-basic beliefs. Despite this, the coherentist interpretation is promising and I develop it further in this (...) paper. I raise the question of whether Kuhn’s account of science can deal with the input objection to coherentism. I argue that the role played by problems in Kuhn’s theory of science ensures that there is input from the external world into scientists’ belief-systems. I follow Hoyningen-Huene in pointing to the causal role played by the external world in determining perceptual states. I next turn to the question of whether Kuhn’s rejection of foundationalism implies coherentism. I argue that Kuhn’s rejection of the one-to-one relation between object and experience is compatible with a foundationalist account of justification. Nor does Kuhn’s rejection of the given entail the same coherentist implications as Sellars’ critique of the myth of the given. (shrink)

According to infinitism, all justification comes from an infinite series of reasons. Peter Klein defends infinitism as the correct solution to the regress problem by rejecting two alternative solutions: foundationalism and coherentism. I focus on Klein's argument against foundationalism, which relies on the premise that there is no justification without meta-justification. This premise is incompatible with dogmatic foundationalism as defended by Michael Huemer and Time Pryor. It does not, however, conflict with non-dogmatic foundationalism. Whereas dogmatic foundationalism rejects the need for (...) any form of meta-justification, non-dogmatic foundationalism merely rejects Laurence BonJour's claim that meta-justification must come from beliefs. Unlike its dogmatic counterpart, non-dogmatic foundationalism can allow for basic beliefs to receive meta-justification from non-doxastic sources such as experiences and memories. Construed thus, non-dogmatic foundationalism is compatible with Klein's principle that there is no justification without meta-justification. I conclude that Klein's rejection of foundationalism. fails. Nevertheless, I agree with Klein that when in response to a skeptical challenge we engage in the activity of defending our beliefs, the number of reasons we can give is at least in principle infinite. I argue that this type of infinity is benign because, when we continue to give reasons, we will eventually merely repeat previously stated reasons. Consequently, I reject Klein's claim that the more reasons we give the more we increase the justification of our beliefs. (shrink)

It is sometimes assumed in the Bayesian coherentist literature that the project of finding a truth-conducive measure of coherence of testimonial contents will, if successful, be helpful to the coherentist theory of justification. Various impossibility results in the Bayesian coherentist literature are consequently taken to be prima facie detrimental to the coherentist theory of justification. These attempts to connect Bayesian coherentism to the coherentist/ foundationalist debate in classical epistemology rest upon a confusion between the justification of a proposition and the (...) credibility that a proposition has for some other proposition. Foundationalism requires a class of beliefs that have non- inferential justification, not beliefs that have credibility by themselves for others. Coherentists insist that beliefs can be justified only via inferential relations with others, but this does not mean that coherentists must deny that individual propositions can have credibility for other propositions. I analyze and respond to both Erik Olsson's and Michael Huemer's arguments concerning the alleged connection between the Bayesian coherentist project and the coherentist theory of justification. Finally, I argue that Bayesian coherentism as represented in the literature, so far from being a version of coherentism, is implicitly foundationalist because of its treatment of “witness reports”, especially the reports of memory and sensation, as given evidence. The impossibility results, based on the assumption of given reports, are therefore not targeted at classical coherentism in epistemology at all. (shrink)

Does the method of reflective equilibrium involve ethical intuitions? If not, what are the so-called “considered judgments” invoked at the beginning of the process of reflective equilibrium? Contrary to the principal tendency in moral and political philosophy, I provide a negative answer to the first question. I hold that ethical intuitions are non-inferential beliefs. I then claim that RE does not involve ethical intuitions because its coherentist character rejects, by definition, any type of non-inferentiality. Concerning the second question above, I (...) provide an answer that preserves the epistemological consistency of RE: considered judgments should be defined as inferential beliefs. The possibility of their inferential character relies on the role of background beliefs in the process of reflective equilibrium. In brief, I criticise and reformulate the standard interpretation of RE by claiming that it does not involve ethical intuitions but only inferential beliefs. (shrink)

Tomoji Shogenji is generally assumed to be the first author to have presented a probabilistic measure of coherence. Interestingly, Rudolf Carnap in his Logical Foundations of Probability discussed a function that is based on the very same idea, namely his well-known relevance measure. This function is largely neglected in the coherence literature because it has been proposed as a measure of evidential support and still is widely conceived as such. The aim of this paper is therefore to investigate Carnap’s measure (...) regarding its plausibility as a candidate for a probabilistic measure of coherence by comparing it to Shogenji’s. It turns out that both measures satisfy and violate the same adequacy constraints, despite not being ordinally equivalent exhibit a strong correlation with each other in a Monte Carlo simulation and perform similarly in a series of test cases for probabilistic coherence measures.

According to the truth-conduciveness problem of coherentism, the coherence theory of justification can hardly show that coherentist justification is truth-conducive. This problem is generally conceived as the most recalcitrant problem with the coherence theory. The purpose of this paper is to show that it does not pose a serious problem for a certain version of coherentism, namely a Sellarsian explanatory coherence theory of justification combined with the deflationary theory of truth. On this version of coherentism, our epistemic goal is to (...) gradually improve our conceptual framework so as to maximize its explanatory coherence, and there is no substantial norm of truth independent of the norms of justification, so that we cannot evaluate the truth-conduciveness of a belief independently of the norms of justification. I argue that this version of coherentism can cope with the truth-conduciveness problem. (shrink)

This paper suggests that text coherence is a multi-factored affair that, ultimately, pertains to the mental organization of episodic memory, most likely as a partially-hierarchic mental structure. What text researchers usually describe as coherence is merely an artifact of the cognitive phenomenon. The role of grammatical clues in signalling text coherence is investigated, and it is suggested that the grammar processing channel merely supplements an evolutionarily older channel of lexically-guided coherence. Coherence is both local and global, and both properties can (...) be signalled by both processing channels. Finally, the establishement of text coherence is a flexible, negotiable process, and this is true of both conversation and narrative. (shrink)

In Reason and Explanation Ted Poston advances an explanatory coherentist view of justification, according to which the justification of a person’s beliefs consists in how well those beliefs fit within a virtuous explanatory system. Poston argues that epistemic conservatism, which holds that in at least some cases belief itself generates epistemic merit, plays an essential role in such an account. Poston’s version of conservatism holds that “mere belief” – belief in cases of empty symmetrical evidence, where the subject lacks any (...) evidence for or against the claim – generates justification for that belief. In this essay I challenge epistemic conservatism; I focus on concerns arising from Poston’s account of conservatism. I then suggest Poston’s view does not need epistemic conservatism and conclude that his project would be more cohesive and compelling if he were to jettison conservatism. (shrink)

One of the most important questions in epistemology and the philosophy of science is: what is a good theory and when is a theory better than another theory, given some observational data? The coherentist‟s answer would be the following twofold conjecture: A theory is a good theory given some observational data iff that theory coheres with the observational data and a theory is better than another theory given some observational data iff the first theory coheres more with the observational data (...) than the second theory. In this paper we show that this answer is a good answer. More precisely, we argue that the coherence measures of Olsson and Shogenji are good measures for the purpose of comparing and evaluating theories, i.e. assessing theories. We do so by clarifying the sufficient and necessary conditions every assessment function must satisfy for being a good measure of the goodness of theories. Afterwards we will show that the coherence measures of Olsson and Shogenji are indeed good assessment functions for assessing theories. (shrink)

Kuhn argued against both the correspondence theory of truth and convergent realism. Although he likely misunderstood the nature of the correspondence theory, which it seems he wrongly believed to be an epistemic theory, Kuhn had an important epistemic point to make. He maintained that any assessment of correspondence between beliefs and reality is not possible, and therefore, the acceptance of beliefs and the presumption of their truthfulness has to be decided on the basis of other criteria. I will show that (...) via Kuhn’s suggested epistemic values, specifically via problem-solving, his philosophy can be incorporated into a coherentist epistemology. Further, coherentism is, in principle, compatible with convergent realism. However, an argument for increasing likeness to truth requires appropriate historical continuity. Kuhn maintained that the history of science is full of discontinuity, and therefore, the historical condition of convergent realism is not satisfied.Keywords: Thomas Kuhn; The correspondence theory of truth; The coherence theory of justification; Convergent realism; Rationalism.
