In this paper, I take scientific models to be epistemic representations of their target systems. I define an epistemic representation to be a tool for gaining information about its target system and argue that a vehicle’s capacity to provide specific information about its target system—its informativeness—is an essential feature of this kind of representation. I draw an analogy to our ordinary notion of interpretation to show that a user’s aim of faithfully representing the target system is (...) necessary for securing this feature. (shrink)

In this paper, I characterize visual epistemic representations as concrete two- or three-dimensional tools for conveying information about aspects of their target systems or phenomena of interest. I outline two features of successful visual epistemic representation: that the vehicle of representation contain sufficiently accurate information about the phenomenon of interest for the user’s purpose, and that it convey this information to the user in a manner that makes it readily available to her. I argue that actual (...) epistemic representation may involve tradeoffs between these and is successful to the extent that they are present. (shrink)

Management theory is a diverse field where multiple theoretical perspectives coexist and coevolve, leading to conceptual pluralism. While conceptual pluralism is useful for grasping different aspects of the complex reality we live in, it may limit the further development of knowledge on elemental concepts. In this article, we focus on knowledge on the natural environment (NE) in management theory. We argue that management scholars and practitioners often rely on theoretical lenses that tend to reify the NE, thereby limiting the conceptualization (...) of some of the essential properties of the NE. Drawing on the example of the conceptual development of the ecosystem services (ES) at the intersection of economics and biology, we identify the advantages and the limits of interdisciplinary theory-building and testing. Finally, we discuss how tools from the philosophy of science can be useful for proposing a way forward for integrating reliable knowledge on the natural environment in management theory. (shrink)

This book defends a two-tiered account of epistemic representation--the sort of representation relation that holds between representations such as maps and scientific models and their targets. It defends a interpretational account of epistemic representation and a structural similarity account of overall faithful epistemic representation.

Epistemic justifications for democracy have been offered in terms of two different aspects of decision-making: voting and deliberation, or ‘votes’ and ‘talk.’ The Condorcet Jury Theorem is appealed to as a justification in terms votes, and the Hong-Page “Diversity Trumps Ability” result is appealed to as a justification in terms of deliberation. Both of these, however, are most plausibly construed as models of direct democracy, with full and direct participation across the population. In this paper, we explore how these (...) results hold up if we vary the model so as to reflect the more familiar democratic structure of a representative hierarchy. We first recount extant analytic work that shows that representation inevitably weakens the voting results of the Condorcet Jury Theorem, but we question the ability of that result to shine light on real representative systems. We then show that, when we move from votes to talk, as modeled in Hong-Page, representation holds its own and even has a slight edge. (shrink)

Epistemic Logic is our basic universal science, the method of our cognitive confrontation in reality to prove the truth of our basic cognitions and theories. Hence, by proving their true representation of reality we can self-control ourselves in it, and thus refuting the Berkeleyian solipsism and Kantian a priorism. The conception of epistemic logic is that only by proving our true representation of reality we achieve our knowledge of it, and thus we can prove our cognitions (...) to be either true or rather false, and otherwise they are doubtful. Therefore, truth cannot be separated from being proved and we cannot hold anymore the principle of excluded middle, as it is with formal semantics of metaphysical realism. In distinction, the intuitionistic logic is based on subjective intellectual feeling of correctness in constructing proofs, and thus it is epistemologically encapsulated in the metaphysical subject. However, epistemic logic is our basic science which enable us to prove the truth of our cognitions, including the epistemic logic itself. (shrink)

This chapter presents a re-understanding of the contents of our analog magnitude representations (e.g., approximate duration, distance, number). The approximate number system (ANS) is considered, which supports numerical representations that are widely described as fuzzy, noisy, and limited in their representational power. The contention is made that these characterizations are largely based on misunderstandings—that what has been called “noise” and “fuzziness” is actually an important epistemic signal of confidence in one’s estimate of the value. Rather than the ANS having (...) noisy or fuzzy numerical content, it is suggested that the ANS has exquisitely precise numerical content that is subject to epistemic limitations. Similar considerations will arise for other analog representations. The chapter discusses how this new understanding of ANS representations recasts the learnability problem for number and the conceptual changes that children must accomplish in the number domain.

In a previous Philo article, it was shown how properties could be ontologically dispensed with via a representational analysis: to be an X is to comprehensively represent all the properties of an X. The current paper extends that representationalist (RT) theory by explaining representation itself in parallel epistemic rather than ontological terms. On this extended RT (ERT) theory, representations of X, as well as the real X, both may be identified as providing information about X, whether partial or (...) comprehensive. But that information does not match ontological, property-based analyses of X, so it is epistemically fundamental–hence supporting a broadly conceptualist rather than nominalist metaphysics.

Assuming that votes are independent, the epistemically optimal procedure in a binary collective choice problem is known to be a weighted supermajority rule with weights given by personal log-likelihood-ratios. It is shown here that an analogous result holds in a much more general model. Firstly, the result follows from a more basic principle than expected-utility maximisation, namely from an axiom (Epistemic Monotonicity) which requires neither utilities nor prior probabilities of the ‘correctness’ of alternatives. Secondly, a person’s input need not (...) be a vote for an alternative, it may be any type of input, for instance a subjective degree of belief or probability of the correctness of one of the alternatives. The case of a profile of subjective degrees of belief is particularly appealing, since here no parameters such as competence parameters need to be known. (shrink)

The thesis concerns itself with the selection constraints governing the basic distributional patterns of five complement constructions in English--the bare clause, the that-clause, the interrogative, the concealed question construction and the exclamative complement--across a wide array of knowledge, belief and communication predicates. The relevant distributional phenomena--which predicates are capable of embedding which complement types--have traditionally been captured by stipulative grammatical markings such as subcategorization frames, semantic selection frames and case-theoretic lexical markings. These theoretical tools, even to the extent that they (...) successfully reduplicate the observed phenomena, are of no explanatory value, as they do not derive the different behavioral patterns from some independently established properties of the embedding predicates or their complements. In the thesis, I present an epistemically-based theory, which attempts to derive the relevant distributional phenomena, including those traditionally assumed to reflect hard-core syntactic idiosyncrasies, from a linguistic-epistemic theory of knowledge, belief and communication. ;The theory is based on a lexical-semantic analysis of the embedding predicates, according to which they denote ternary relations between agents, objects of attitude and objects of representation. Thus, to give an example, the predicate think denotes a ternary relation between a thinker, a thought mentally represented by the thinker, and a proposition expressed by the thought and believed by the thinker to be true. This analysis, developed on linguistic grounds for linguistic purposes, echoes some of the recent insights in the philosophy of mind, especially Crimmins . Coupled with a theory of the meanings of the different complement types--partially based on the formal semantic insights of Karttunen , Groenedijk and Stokhof and Ginzburg --this account derives the distributional patterns from simple considerations of semantic compatibility: those predicates which are capable of embedding a certain complement type are exactly those whose lexical semantics is compatible with the semantics of the complement. ;Some of the distributional patterns discussed in the thesis, especially the one involving concealed questions, have traditionally been taken to provide empirical support for the hypothesis of the autonomy of syntactic representations . The analysis presented in this thesis reveals the dramatic extent to which the semantics and the syntax of lexical selection are transparent to each other, and thus implies, at least with respect to the core domain of lexical selection, that the autonomy hypothesis is empirically unjustified.

In this paper I argue that the representational theory of perception, on which the world is represented as being a certain way in perceptual experience, cannot explain how there can be a genuinely epistemic connection between experience and belief. I try to show that we are positively required to deny that perceptual consciousness is contentful if we want to make its fitness for epistemic duties intelligible. (So versions of the representational theory on which experience has a merely causal (...) purchase on belief are not considered.) But my aim is not just negative. I try to defeat representationalism in such a way as to motivate a robustly presentational theory of perception. According to such a theory, perceptions are relations not between a subject and a content but between a subject and an ordinary object (such that if the relation holds at t, an appropriate subject and object must exist at t, and the object must be presented to the subject). I end by sketching an account of perceptual experience that is meant to show that, contrary to a very popular misconception, there is a way to conceive perceptual consciousness as relational and presentational (not intentional and representational) that does not succumb to the celebrated ?myth of the Given?

A central idea in Ruth Millikan’s biosemantics is that a representation’s content is restricted to conditions required for the normal success of actions that it has as its function to guide. This paper raises and responds to a problem for this idea. The problem is that the success requirement seems to block us from saying that epistemic modal judgments represent our epistemic circumstances. For the normal success of actions guided by these judgments seems to depend on what (...) is actually the case, not on whether or to what extent various possibilities were supported by our evidence. In response, I argue, first, that actions guided by epistemic modal judgments have as their function to implement strategies for handling epistemic circumstances, second, that the successful performance of this function requires that aspects of these circumstances obtain, and, third, that biosemantics can thus understand epistemic modal judgments as representing these aspects. The recognition of such strategic contents introduces complications; I further argue that these are benign. (shrink)

Epistemic interactivism, an aspect of the epistemology of representation, is a cognitive intercourse between the subject and person-object of knowledge that underlies the conception of a person in Esan thought. Traditional theories of representation (especially as presented by Descartes and Locke) separated the subject from the object of knowledge, and classified persons and non-persons as object of knowledge. This separation and classification ignored the cognitive and moral values of persons, disengaged the subject from the world and burden (...) the self with solitude and isolation, and created propositional knowledge that dehumanised the relationship between the subject and person-object of knowledge. Within the theoretical framework of Hegel's epistemic interactivism (meliorated by Bowne's personalism) and Esan epistemology (in African philosophy), this book exposes the epistemic interactivism of Esan thought which unified the subject and person-object of knowledge on cognitive and moral grounds; thus providing adequate basis for personhood and resolving the dehumanised relationship between the subject and person-object of knowledge in the traditional theories of representation. Within the context of epistemic injustices, this book analyses the interactivist epistemology of indigenous Esan thought as an alternative epistemological conception of the person-object of knowledge which resolves the deficiency of the traditional theories of representation.

The aim of this paper is to present a strongly complete first order functional predicate calculus generalized to models containing not only ordinary classical total functions but also arbitrary partial functions. The completeness proof follows Henkin’s approach, but instead of using maximally consistent sets, we define saturated deductively closed consistent sets . This provides not only a completeness theorem but a representation theorem: any SDCCS defines a canonical model which determine a unique partial value for every predicate symbol and (...) any function symbol. Any SDCCS can thus be interpreted as an epistemic state. (shrink)

The representational epistemic approach to the design of visual displays and notation systems advocates encoding the fundamental conceptual structure of a knowledge domain directly in the structure of a representational system. It is claimed that representations so designed will benefit from greater semantic transparency, which enhances comprehension and ease of learning, and plastic generativity, which makes the meaningful manipulation of the representation easier and less error prone. Epistemic principles for encoding fundamental conceptual structures directly in representational schemes (...) are described. The diagrammatic recodification of probability theory is undertaken to demonstrate how the fundamental conceptual structure of a knowledge domain can be analyzed, how the identified conceptual structure may be encoded in a representational system, and the cognitive benefits that follow. An experiment shows the new probability space diagrams are superior to the conventional approach for learning this conceptually challenging topic. (shrink)

Epistemic modal operators give rise to something very like, but also very unlike, Moore's paradox. I set out the puzzling phenomena, explain why a standard relational semantics for these operators cannot handle them, and recommend an alternative semantics. A pragmatics appropriate to the semantics is developed and interactions between the semantics, the pragmatics, and the definition of consequence are investigated. The semantics is then extended to probability operators. Some problems and prospects for probabilistic representations of content and context are (...) explored. (shrink)

The notion of epistemic responsibility applied to memory has been in general examined in the framework of the responsibilities that a collective holds for past injustices, but it has never been the object of an analysis of its own. In this article, I propose to isolate and explore it in detail. For this purpose, I start by conceptualizing the epistemic responsibility applied to individual memories. I conclude that an epistemic responsible individual rememberer is a vigilant agent who (...) knows when to engage in different kinds of mental and non-mental actions in order to monitor and update her memories, and who develops and nurture different kinds of virtuous attitudes that guide those actions. These (epistemic) virtuous attitudes are oriented not only towards herself but also towards others. Whereas this conception of epistemic responsibility does not pose a problem to understand shared memories of family members and friends, it may seem suspicious when applied to large-scale collective memories. These memories, which I name historical memories, are memories of events that have a traumatic impact for the community, are permeated by unequal relations of power, keep a complex relationship with historical science, and present other characteristics that distinguish them from individual memories. But despite these differences, the analysis undertaken in this work shows that the general principles that govern the epistemic responsibility of individual and (large-scale) collective rememberers are similar, and are based on similar grounds: pragmatic considerations about the consequences of misremembering or forgetting and a feeling of care. The similarities at the individual and collective scale of the epistemic vigilant attitude that is and should be taken toward our significant past may partially justify the use of the same epithet—“memory”—to refer to these different kinds of representations.

Epistemologists have long believed that epistemic luck undermines propositional knowledge. Action theorists have long believed that agentive luck undermines intentional action. But is there a relationship between agentive luck and epistemic luck? While agentive luck and epistemic luck have been widely thought to be independent phenomena, we argue that agentive luck has an epistemic dimension. We present several thought experiments where epistemic luck seems to undermine both knowledge-how and intentional action and we report experimental results (...) that corroborate these judgments. These findings have implications for the role of knowledge in a theory of intentional action and for debates about the nature of knowledge-how and the significance of knowledge representation in folk psychology.

There is a variety of epistemic roles to which photographs are better suited than non-photographic pictures. Photographs provide more compelling evidence of the existence of the scenes they depict than non-photographic pictures. They are also better sources of information about features of those scenes that are easily overlooked. This chapter examines several different attempts to explain the distinctive epistemic value of photographs, and argues that none is adequate. It then proposes an alternative explanation of their epistemic value. (...) The chapter argues that photographs play the epistemic roles they do because they are typically rich sources of depictively encoded information about the scenes they depict, and reliable depictive representations of those scenes. It then explains why photographs differ from non-photographic pictures in both respects. (shrink)

The Stoics thought that knowledge depends on a special kind of appearances which they called ‘apprehensive’, which are by definition true. Interestingly, Sextus Empiricus reports in M 7.247 that they held that there are appearances that are true but that are not apprehensive because they are true merely by chance and thus cannot constitute knowledge. I believe that this suggests that the Stoics were aware of what is in modern literature known as the problem of epistemic luck. Unfortunately, Sextus’ (...) report leaves out a lot of important details, which makes it difficult to understand exactly which appearances the Stoics thought are true by chance, and why. I argue that the true non-apprehensive appearances in question here are imaginations, representational states which are not immediately caused by external objects through perception, but produced solely by the mind. I propose an explanation why the Stoics, who defined chance in terms of hidden causes, would have thought that imaginations can only be true by chance. The explanation stems from their view that the essential characteristic of imagination is that it leaves the actual cause of its representational content hidden from the subject. (shrink)

In this paper, I develop Mauricio Suárez’s distinction between denotation, epistemic representation, and faithful epistemic representation. I then outline an interpretational account of epistemic representation, according to which a vehicle represents a target for a certain user if and only if the user adopts an interpretation of the vehicle in terms of the target, which would allow them to perform valid (but not necessarily sound) surrogative inferences from the model to the system. The main (...) difference between the interpretational conception I defend here and Suárez’s inferential conception is that the interpretational account is a substantial account—interpretation is not just a “symptom” of representation; it is what makes something an epistemic representation of a something else.

o formalization of intensional functions was made for the purpose of many-valued interpretation of the belief-operators within the scope of the classical logic system. The first aim of the paper is to present and discuss this rather unknown many-valued construction and its properties. The fact that the manyvaluedness of o systems is purely formal - their characteristic matrices are Boolean - calls for further consideration. Departing from intristic similarities of the tables for the epistemic operators to the information functions (...) we show that o structures may be rewritten as special knowledge representation systems. These systems use 0 and 1 as the only values and are called “epistemic”. Their role for the theory of knowledge information systems may be compared to that of the functionally complete matrices in the class of all logical matrices for a given propositional language.

Visual representations (photographs, diagrams, etc.) play crucial roles in scientific processes. They help, for example, to communicate research results and hypotheses to scientific peers as well as to the lay audience. In genuine research activities they are used as evidence or as surrogates for research objects which are otherwise cognitively inaccessible. Despite their important functional roles in scientific practices, philosophers of science have more or less neglected visual representations in their analyses of epistemic methods and tools of reasoning in (...) science. This book is meant to fill this gap. It presents a detailed investigation into central conceptual issues and into the epistemology of visual representations in science. (shrink)

In this position paper, we introduce a new epistemic lens for analyzing algorithmic harm. We argue that the epistemic lens we propose herein has two key contributions to help reframe and address some of the assumptions underlying inquiries into algorithmic fairness. First, we argue that using the framework of epistemic injustice helps to identify the root causes of harms currently framed as instances of representational harm. We suggest that the epistemic lens offers a theoretical foundation for (...) expanding approaches to algorithmic fairness in order to address a wider range of harms not recognized by existing technical or legal definitions. Second, we argue that the epistemic lens helps to identify the epistemic goals of inquiries into algorithmic fairness. There are two distinct contexts within which we examine algorithmic harm: at times, we seek to understand and describe the world as it is, and, at other times, we seek to build a more just future. The epistemic lens can serve to direct our attention to the epistemic frameworks that shape our interpretations of the world as it is and the ways we envision possible futures. Clarity with respect to which epistemic context is relevant in a given inquiry can further help inform choices among the different ways of measuring and addressing algorithmic harms. We introduce this framework with the goal of initiating new research directions bridging philosophical, legal, and technical approaches to understanding and mitigating algorithmic harms. (shrink)

El desarrollo de la argumentación en el proceso de alfabetización académica cobra especial importancia debido a que el conocimiento académico es esencialmente argumentativo.

Callender and Cohen have proposed to apply a “Gricean strategy” to the constitution problem of scientific representation, taking inspiration from Grice’s reduction of linguistic meaning to mental states. They suggest that scientific representation can be reduced to stipulation by epistemic agents. This account has been criticised for not making a distinction between symbolic and epistemic representation and not taking into account the communal aspects of scientific representation. I argue that these criticisms would not apply (...) if Grice’s actual strategy were properly employed. I present Grice’s account of linguistic meaning and transpose his actual strategy and method to epistemic representation. This results in a reduction of epistemic representation to mental states that does not fall prey to the same criticisms. The main novelty of the resulting account is a distinction between contextual representational use and general representational status, which I address using the notion of indexicality. (shrink)

What, if anything, is epistemically wrong with beliefs involving accurate statistical generalizations about demographic groups? This paper argues that there is a perfectly general, underappreciated epistemic flaw which affects both ethically charged and uncharged statistical generalizations. Though common to both, this flaw can also explain why demographic statistical generalizations give rise to the concerns they do. To identify this flaw, we need to distinguish between the accuracy and the projectability of statistical beliefs. Statistical beliefs are accompanied by an implicit (...) representation of the statistic's modal profile. Their modal profile determines the circumstances in which they can legitimately be projected to unobserved instances. Errors in that implicit content can be compatible with the accuracy of the “bare” statistic, whilst systematically leading to downstream errors in reasoning, in a manner which reveals an epistemic flaw with an important aspect of the belief state itself.

The ontic conception of explanation is predicated on the proposition that “explanation is a relation between real objects in the world” and hence, according to this approach, scientific explanation cannot take place absent such a premise. Despite the fact that critics have emphasized several drawbacks of the ontic conception, as for example its inability to address the so-called “abstract explanations”, the debate is not settled and the ontic view can claim to capture cases of explanation that are non-abstract, such as (...) causal relations between events. However, by eliminating the distinction between abstract and non-abstract explanations, it follows that ontic and epistemic proposals can no longer contend to capture different cases of explanation and either all are captured by the ontic view or all are captured by the epistemic view. On closer inspection, it turns out that the ontic view deals with events that fall outside the scientists’ scope of observation and that it does not accommodate common instances of explanation such as explanations from false propositions and hence it cannot establish itself as the dominant philosophical stance with respect to explanation. On the contrary, the epistemic conception does account for almost all episodes of explanation and can be described as a relation between representations, whereby the explanans transmit information to the explanandum and that this information can come, dependent on context, in the form of any of the available theories of explanation (law-like, unificatory, causal and non-causal). The range of application of the ontic view thus is severely restricted to trivial cases of explanation that come through direct observation of the events involved in an explanation and explanation is to be mostly conceived epistemically.

The epistemic value of models has traditionally been approached from a representational perspective. This paper argues that the artifactual approach evades the problem of accounting for representation and better accommodates the modal dimension of modeling. From an artifactual perspective, models are viewed as erotetic vehicles constrained by their construction and available representational tools. The modal dimension of modeling is approached through two case studies. The first portrays mathematical modeling in economics, while the other discusses the modeling practice of (...) synthetic biology, which exploits and combines models in various modes and media. Neither model intends to represent any actual target system. Rather, they are constructed to study possible mechanisms through the construction of a model system with built-in dependencies. (shrink)

According to a traditional picture, perception and belief have starkly different epistemic roles. Beliefs have epistemic statuses as justified or unjustified, depending on how they are formed and maintained. In contrast, perceptions are “unjustified justifiers.” Core cognition is a set of mental systems that stand at the border of perception and belief, and has been extensively studied in developmental psychology. Core cognition's borderline states do not fit neatly into the traditional epistemic picture. What is the epistemic (...) role of these states? Focusing on the core object system, the author argues that core object representations have epistemic statuses like beliefs do, despite their many prototypically perceptual features. First, the author argues that it is a sufficient condition on a mental state's having an epistemic status as justified or unjustified that the state is based on reasons. Then the author argues that core object representations are based on reasons, through an examination of both experimental results and key markers of the basing relation. The scope of mental states that are subject to epistemic evaluation as justified or unjustified is not restricted to beliefs. (shrink)

The paper is an opinionated tour of the literature on the reasons for which we hold beliefs and other doxastic attitudes, which I call ‘operative epistemic reasons’. After drawing some distinctions in §1, I begin in §2 by discussing the ontology of operative epistemic reasons, assessing arguments for and against the view that they are mental states. I recommend a pluralist non-mentalist view that takes seriously the variety of operative epistemic reasons ascriptions and allows these reasons to (...) be both propositions and truth-making facts. In §3, I turn to consider what it takes for a consideration to be an operative epistemic reason, examining three conditions – the representational, treating, and explanatory conditions – that have been proposed. I offer a novel view about the explanatory condition. In §4, I discuss the special case of inferential operative reasons and examine attempts to understand them in terms of rule-following, sketching a competence-based spinoff of dispositionalism. Finally, in §5, I consider whether there are non-inferential operative reasons, observing that one needn't countenance them to be a foundationalist but then developing a view about what they are and how they do and don't differ from inferential reasons.

Representation has been one of the main themes in the recent discussion of models. Several authors have argued for a pragmatic approach to representation that takes users and their interpretations into account. It appears to me, however, that this emphasis on representation places excessive limitations on our view of models and their epistemic value. Models should rather be thought of as epistemic artifacts through which we gain knowledge in diverse ways. Approaching models this way stresses (...) their materiality and media-specificity. Focusing on models as multi-functional artifacts loosens them from any pre-established and fixed representational relationships and leads me to argue for a two-fold approach to representation.

The notion of scientific representation plays a central role in current debates on modeling in the sciences. One or maybe the major epistemic virtue of successful models is their capacity to adequately represent specific phenomena or target systems. According to similarity views of scientific representation, models should be similar to their corresponding targets in order to represent them. In this paper, Suárez’s arguments against similarity views of representation will be scrutinized. The upshot is that the intuition (...) that scientific representation involves similarity is not refuted by the arguments. The arguments do not make the case for the strong claim that similarity between vehicles and targets is neither necessary nor sufficient for scientific representation. Especially, one claim that a similarity view wants to uphold, still, is the following thesis: only if a vehicle is similar to a target in relevant respects and to a specific degree of similarity then the vehicle is a scientific representation of that target.

What is epistemic self-trust? There is a tension in the way in which prominent accounts answer this question. Many construe epistemic trust in oneself as no more than reliance on our sub-personal cognitive faculties. Yet many accounts – often the same ones – construe epistemic trust in others as a normatively laden attitude directed at persons whom we expect to care about our epistemic needs. Is epistemic self-trust really so different from epistemic trust in (...) others? I argue that it is not. We certainly do rely on our cognitive faculties to achieve epistemic ends; but I argue that we also have the normatively rich sort of epistemic trust in ourselves. Moreover, there is a theoretical need for this normatively rich notion of epistemic self-trust: positing it yields the best account of how we secure important epistemic goods, including knowledge and recognition as knowers. I argue this by giving an account of epistemic trust in others and showing that it can be generalized to epistemic trust in oneself. (shrink)

Scientific research is constrained by limited resources, so it is imperative that it be conducted efficiently. This paper introduces the notion of epistemic expression, a kind of representation that expedites the solution of research problems. Epistemic expressions are representations that (i) contain information in a way that enables more reliable information to place the most stringent constraints on possible solutions and (ii) make new information readily extractible by biasing the search through that space. I illustrate these conditions (...) using historical and contemporary examples of biomolecular structure determination. Then, I argue that the notion of epistemic expression parts ways with pragmatic accounts of scientific representation and an understanding of models as artifacts, neither of which require models to accurately represent. Explicating epistemic expression thus fills a gap in our understanding of scientific practice, extending Morrison and Morgan's (1999) conception of models as investigative instruments. (shrink)

Review of Joseph Y. Halpern (ed.), Theoretical Aspects of Reasoning About Knowledge: Proceedings of the 1986 Conference (Los Altos, CA: Morgan Kaufmann, 1986),.

The imagination is ubiquitous in our cognitive lives. You might imagine rotating a puzzle piece to determine whether it fits in an open space, or imagine what things are like from another person's perspective to figure out how they are feeling, or imagine a new rug in your living room to determine whether it matches the color of your sofa. These examples are mundane, but they point to a deep philosophical puzzle: how could merely imagining something give you any reason (...) to believe that it is true? After all, you can imagine anything you want to, from the fictional to the fantastical. This has led many philosophers to be deeply skeptical of the epistemic value of the imagination. When imagination is accorded a justificatory role, it is typically limited to beliefs about what is metaphysically possible. More recently, some philosophers have begun to push back against this orthodoxy by arguing that the imagination can justify empirical beliefs about the actual world. But even then, most contemporary discussions focus on whether the imagination can justify empirical belief, rather than on how the imagination justifies empirical belief, thereby leaving many central questions about the epistemology of the imagination unanswered. This dissertation attempts to fill this lacuna by canvassing the theoretical landscape of this exciting new literature and developing an account of the epistemic structure of the imagination. The first chapter sets the stage for the rest of the dissertation by reviewing extant arguments for and against the view that the imagination can justify empirical belief before posing a new argument in its favor. The second chapter argues that imaginative justification is mediate but non-inferential; it depends on one’s prior justification without depending on an inference from one’s prior beliefs. The third chapter argues that the imagination is informative—it can represent new content and generate new justification—in virtue of its analog representational format. The fourth and final chapter argues that some imaginings just are beliefs, and that this grounds their justificatory force. Together, the arguments of this dissertation suggest that the imagination is a distinctive kind of ampliative reasoning, and that it plays this cognitive and epistemic role by combining the analog representational format of imagery with the evidence-sensitive function of belief.

Determinism fails easily if spacetimes with points removed from the spacetime manifold are taken to be physically reasonable representations of a way the world could be according to classical general relativity. I discuss a recently proposed condition for determining which spacetimes have holes—epistemic hole freeness—and show that epistemic hole freeness gives the correct verdict in some non-globally hyperbolic spacetimes with a closed subset removed, certain spacetimes with genuinely indeterministic features count as having an epistemic hole, which implies (...) that the requirement of epistemic hole freeness enforces a form of determinism, and there is a large class of spacetimes that intuitively are radically indeterministic and unphysical due to containing a hole, but are free from epistemic holes. I show that a few natural ways of remedying are not satisfactory. (shrink)

Feminist epistemology aims to propose epistemic reasons for increasing the representation of women or socially subordinated people in science. This is typically done—albeit often only implicitly—by positing a causal mechanism through which the representation of sociodemographic minorities exerts a positive effect on scientific advancement. Two types of causal theories can be identified. The “epistemic diversity thesis” presents a causal path from sociodemographic diversity to scientific progress mediated by epistemic diversity. The “thesis of epistemic advantage” (...) proposes a causal path from social subjugation to capacity for inquiry. The latter theory is defined with substantial ambiguity in the existing literature, and I present an explicit causal reformulation that disambiguates it. The epistemic diversity thesis focuses on the effect of group composition on collective epistemic performance and is largely silent about what kind of characteristics lead to individual epistemic excellence. On the other hand, the thesis of epistemic advantage seeks to identify sociodemographic background conditions that make certain epistemic agents strictly better knowers or inquirers than others and pays little attention to the synergistic effects of diverse group composition. Such a difference in the causal structure reflects the diverging political characteristics of the two theories. (shrink)

Epistemologists frequently claim that the question “What should I believe?” demarcates the field of epistemology. This question is then compared to the question asked in ethics: “What should I do?” The question and the ensuing comparison, it is thought, specify both the content and the normativity at stake in epistemology. I argue that both of the assumptions embedded in this demarcation are problematic. By thinking of epistemology’s focal question in this light, first, we risk importing our assumptions about the (...) class='Hi'>epistemic domain into our understanding of the nature and normativity of the belief state, and second, we come to have a false picture of the normativity that supposedly underlies the domain. In Chapter 1, “The Doxastic Account of the Epistemic”, I explore a range of views that assume there to be an essential connection between belief and truth. I look at views that treat all beliefs as attempts to believe the truth, views that consider belief’s biological function to be accurate representation, and views that hold that the very concept of belief is a normative concept. I go on to explore instrumentalist conceptions of belief’s truth connection and conduct an inquiry into the value of true belief. I conclude that neither the value of true belief nor an essential connection between belief and truth can explain epistemic normativity. In Chapter 2, “Evidential Exclusivity, Correctness, and the Nature of Belief” I note that epistemologists have recently argued that the best explanation for the apparent truth of a pair of claims - “Transparency” and “Exclusivity” – is that belief is subject to a standard of correctness such that a belief that p is correct if and only if p is true. I argue that the proposed explanation unduly privileges one part of belief’s full functional profile – its role in deliberation – and that a more complete consideration of belief’s role in cognition suggests an alternative explanation for Exclusivity and Transparency but denies belief’s standard of correctness. In Chapter 3, “Tradeoffs and Epistemic Value”, I look at a debate about whether epistemic norms are teleological. Though it’s standard to assume in keeping with teleology that certain goals or values explain the content of our norms, a collection of recent papers have aimed to show that this assumption can’t be correct because teleological norms countenance tradeoffs but epistemic norms don’t countenance tradeoffs. I note that the kind of non-teleological view that countenances no tradeoffs whatsoever is actually quite extreme and virtually unheard of in ethics. I go on to make the case that norms that license no tradeoffs can’t reasonably be taken to be grounded in value at all, and thus can’t be understood to give rise to necessary normativity. I conclude by suggesting that we broaden our conception of the epistemic domain to recognize teleological norms that provide recommendations for methods of inquiry or pursuit of significant truth or knowledge.

This paper proposes a logical framework for representing static and dynamic properties of different kinds of individual and collective attitudes. A complete axiomatization as well as a decidability result for the logic are given. The logic is applied to game theory by providing a formal analysis of the epistemic conditions of iterated deletion of weakly dominated strategies (IDWDS), or iterated weak dominance for short. The main difference between the analysis of the epistemic conditions of iterated weak dominance given (...) in this paper and other analysis is that we use a semi-qualitative approach to uncertainty based on the notion of plausibility first introduced by Spohn, whereas other analysis are based on a quantitative representation of uncertainty in terms of probabilities.

This paper examines two recent approaches to the nature and functioning of economic models: models as isolating representations and models as credible constructions. The isolationist view conceives of economic models as surrogate systems that isolate some of the causal mechanisms or tendencies of their respective target systems, while the constructionist approach treats them rather like pure constructions or fictional entities that nevertheless license different kinds of inferences. I will argue that whereas the isolationist view is still tied to the representationalist (...) understanding of models that takes the model-target dyad as the basic unit of analysis, the constructionist perspective can better accommodate the way we actually acquire knowledge through them. Using the example of Tobin’s ultra-Keynesian model I will show how many of the epistemic characteristics of modelling tend to go unrecognised if too much focus is placed on the model-target dyad.
