According to the Dogmatism Puzzle, knowledge breeds dogmatism: if a subject knows a proposition h, then she is justified in disregarding any future evidence against h, for she knows that such evidence is misleading. The standard, widely accepted, solution to the puzzle appeals to the defeasibility of knowledge. I argue that the defeat solution leaves intact a residual dogmatist puzzle. Solving this puzzle requires proponents of defeat to deny a plausible principle that the original puzzle relies on called Entitlement, a (...) principle stating roughly that knowing that a piece of evidence is misleading entitles one to disregard it. The plausibility of Entitlement should cast doubt not only on the defeat solution, but on an assumption that has often been taken for granted: the falsity of the dogmatist conclusion of the original puzzle. I conclude that we face a dilemma between giving up Entitlement and living with dogmatism. (shrink)

One of the central problems afflicting reductionism in the epistemology of testimony is the apparent fact that infants and small children are not cognitively capable of having the inductively based positive reasons required by this view. Since non-reductionism does not impose a requirement of this sort, it is thought to avoid this problem and is therefore taken to have a significant advantage over reductionism. In this paper, however, I argue that if this objection undermines reductionism, then a variant of it (...) similarly undermines non-reductionism. Thus, considerations about the cognitive capacities of infants and small children do not effectively discriminate between these two competing theories of testimonial justification. (shrink)

Sometimes, learning about the origins of a belief can make it irrational to continue to hold that belief—a phenomenon we call ‘genealogical defeat’. According to explanationist accounts, genealogical defeat occurs when one learns that there is no appropriate explanatory connection between one’s belief and the truth. Flatfooted versions of explanationism have been widely and rightly rejected on the grounds that they would disallow beliefs about the future and other inductively-formed beliefs. After motivating the need for some explanationist account, we raise (...) some problems for recent versions of explanationism. Learning from their failures, we then produce and defend a more resilient explanationism. (shrink)

Goodman and Elgin have recommended a reconception of philosophy. A central part of their recommendation is to replace knowledge by understanding. According to Elgin, some important internalist and externalist theories of knowledge favor a sort of undesirable cognitive minimalism. Against Elgin I try to show how the challenge of cognitive minimalism can be met. Goodman and Elgin claim that defeat and confusion are built into the concept of knowledge. They demand either its revision or its replacement or its supplement. I (...) show that these are three very different options. While agreeing with the view that there may be good reasons for some revisions and supplements, I strongly disagree with Elgin and Goodman's replacement thesis. (shrink)

Genetic epistemology analyzes the growth of knowledge both in the individual person (genetic psychology) and in the socio-historical realm (the history of science). But what the relationship is between the history of science and genetic psychology remains unclear. The biogenetic law that ontogeny recapitulates phylogeny is inadequate as a characterization of the relation. A critical examination of Piaget's Introduction à l'Épistémologie Généntique indicates these are several examples of what I call stage laws common to both areas. Furthermore, there is at (...) least one example of a paradoxical inverse relation between the two — geometry. Both similarities and differences between the two domains require an explanation, a developmental explanation. Although such an explanation seems to be psychological in nature, it is not merely empirical but also normative (since psychology is both factual and normative according to Piaget). Hence genetic epistemology need not be reduced to psychology (narrowly conceived), but rather should be seen as being both empirical and normative and thus similar to certain types of contemporary philosophy of science.

Reasoning almost always occurs in the face of incomplete information. Such reasoning is nonmonotonic in the sense that conclusions drawn may later be withdrawn when additional information is obtained. There is an active literature on the problem of modeling such nonmonotonic reasoning, yet no category of method-let alone a single method-has been broadly accepted as the right approach. This paper introduces a new method, called sweeping presumptions, for modeling nonmonotonic reasoning. The main goal of the paper is to provide an (...) example-driven, nontechnical introduction to the method of sweeping presumptions, and thereby to make it plausible that sweeping presumptions can usefully be applied to the problems of nonmonotonic reasoning. The paper discusses a representative sample of examples that have appeared in the literature on nonmonotonic reasoning, and discusses them from the point of view of sweeping presumptions. (shrink)

In this paper, we consider how certain longstanding philosophical questions about mental representation may be answered on the assumption that cognitive and perceptual systems implement hierarchical generative models, such as those discussed within the prediction error minimization framework. We build on existing treatments of representation via structural resemblance, such as those in Gładziejewski :559–582, 2016) and Gładziejewski and Miłkowski, to argue for a representationalist interpretation of the PEM framework. We further motivate the proposed approach to content by arguing that it (...) is consistent with approaches implicit in theories of unsupervised learning in neural networks. In the course of this discussion, we argue that the structural representation proposal, properly understood, has more in common with functional-role than with causal/informational or teleosemantic theories. In the remainder of the paper, we describe the PEM framework for approximate Bayesian inference in some detail, and discuss how structural representations might arise within the proposed Bayesian hierarchies. After explicating the notion of variational inference, we define a subjectively accessible measure of misrepresentation for hierarchical Bayesian networks by appeal to the Kullbach–Leibler divergence between posterior generative and approximate recognition densities, and discuss a related measure of objective misrepresentation in terms of correspondence with the facts.

This paper treats two problem cases in decision theory, the Newcomb problem and Reed Richter''s Button III. Although I argue that, contrary to Richter, the latter case does not constitute a genuine counterexample to a standard general proposition of (causal) decision theory, I agree with and undertake to amplify his solution to the decision problem in Button III. I then apply the conclusions and distinctions in the foregoing treatment of Button III to the Newcomb problem and argue that a familiar (...) version of the dominance argument for taking both boxes runs afoul of plausible general constraints on rational agency. The underlying theme of the paper is that basic considerations of epistemic coherence play an important role in dealing with problem cases in decision theory. (shrink)

A Moorean fact, in the words of the late David Lewis, is ‘one of those things that we know better than we know the premises of any philosophical argument to the contrary’. Lewis opens his seminal paper ‘Elusive Knowledge’ with the following declaration.

Throughout the history of western philosophy, the Socratic injunction to ‘follow the argument where it leads’ has exerted a powerful attraction. But what is it, exactly, to follow the argument where it leads? I explore this intellectual ideal and offer a modest proposal as to how we should understand it. On my proposal, following the argument where it leaves involves a kind of modalized reasonableness. I then consider the relationship between the ideal and common sense or ‘Moorean’ responses to revisionary (...) philosophical theorizing. (shrink)

In this age of post-Moorean modesty, many of us are inclined to doubt that philosophy is in possession of arguments that might genuinely serve to undermine what we ordinarily believe. It may perhaps be conceded that the arguments of the skeptic appear to be utterly compelling; but the Mooreans among us will hold that the very plausibility of our ordinary beliefs is reason enough for supposing that there must be something wrong in the skeptic’s arguments, even if we are unable (...) to say what it is. In so far then, as the pretensions of philosophy to provide a world view rest upon its.. (shrink)

The aim of this paper is to provide the beginnings of a theory of justification. This theory is an alternative to the two currently available and unsatisfactory options: foundationalism and coherentism. Both of these theories, as well as the decisive sceptical objections to them, are committed to the assumption that there is only one context of justification and only one standard of justification. This assumption is mistaken. There are two contexts of justification, each with a standard peculiar to it. The (...) consequence of this is the need for a radical reorientation in epistemology.

Meaning Holism and Contextualism are standardly acknowledged to be similar relativistic theories that often lead to similar troubles, in particular to issues concerning instability. On the other hand, the main rival of Contextualism, which is Minimalism, is taken to be resistant to these problems. In effect, it seems inevitable to see Meaning Holism and Minimalism as natural enemies. In my paper, I attempt to reject such a view. My argumentation consists of three main parts. First, I argue that Minimalism does (...) not differ that much from Meaning Holism with respect to the instability issues as it also faces some of them (although in a slightly different way from the case of Holism of Contextualism). Second, I put forward several arguments to show that in fact Minimalism is not incompatible with the two versions of Meaning Holism I distinguish, namely Global Holism and Local Holism. I argue that a meaning holist has to accept some not uncontroversial principles to become an anti- minimalist – and vice versa. Finally, I demonstrate that Minimalism and Meaning Holism can be reconciled. Such a possibility occurs when something I called ‘purely semantic processes’ is allowed. The role of these processes is, roughly speaking, to protect literal meanings from being affected by strong pragmatic factors. (shrink)

Everyday reasoning is replete with arguments which, though not logically valid, nonetheless harbor a measure of credibility in their own right. Here the claim that such arguments force us to acknowledge material validity, in addition to logical validity, is advanced, and criteria that attempt to unpack this concept are examined in detail. Of special concern is the effort to model these criteria on explications of logical validity that rely on notions of substitutivity and logical form. It is argued, however, that (...) such a parallel is not easily located and that it is uncertain that a construal of material validity can be fashioned after traditional accounts of logical validity. Attention is also given to the topics of enthymemes and to the proper domain of logic. (shrink)

This paper explores speakers'' epistemic access to the semanticand syntactic features of sentences of their language. I argue that there is evidence that ceteris paribus, the actual semantic features of sentences of a language are accessible as such by typical speakers of that language.I then explore various linguistic, cognitive, and epistemic consequences of this position.

The empirical nature of our understanding of language is explored. I first show that there are several important and different distinctions between tacit and accessible awareness. I then present empirical evidence concerning our understanding of language. The data suggests that our awareness of sentence-meanings is sometimes merely tacit according to one of these distinctions, but is accessible according to another. I present and defend an interpretation of this mixed view. The present project is shown to impact on several diverse areas, (...) including inferential role semantics and holism, the nature of learning, and the role of linguistics in the law. (shrink)

Logical psychologism is the position that logic is a special branch of psychology, that logical laws are descriptíons of experience to be arrived at through observation, and are a posteriori.The accepted arguments against logical psychologism are effective only when directed against this extreme version. However, the clauses in the above characterization are independent and ambiguous, and may be considered separately. This separation permits a reconsideration of less extreme attempts to tie logic to psychology, such as those defended by Mill and (...) Boole. It also provides the basis for a reexamination of the relationship between logic and psychology, and raises the possibility of a deeper investigation into the nature of logic itself. (shrink)

This article reviews some linguistic and philosophical work in lexical semantics. In Section 1, the general methods of lexical semantics are explored, with particular attention to how semantic features of verbs are associated with grammatical patterns. In Section 2, philosophical consequences and issues arising from this sort of research is reviewed.

Abstract Theories of induction in psychology and artificial intelligence assume that the process leads from observation and knowledge to the formulation of linguistic conjectures. This paper proposes instead that the process yields mental models of phenomena. It uses this hypothesis to distinguish between deduction, induction, and creative forms of thought. It shows how models could underlie inductions about specific matters. In the domain of linguistic conjectures, there are many possible inductive generalizations of a conjecture. In the domain of models, however, (...) generalization calls for only a single operation: the addition of information to a model. If the information to be added is inconsistent with the model, then it eliminates the model as false: this operation suffices for all generalizations in a Boolean domain. Otherwise, the information that is added may have effects equivalent (a) to the replacement of an existential quantifier by a universal quantifier, or (b) to the promotion of an existential quantifier from inside to outside the scope of a universal quantifier. The latter operation is novel, and does not seem to have been used in any linguistic theory of induction. Finally, the paper describes a set of constraints on human induction, and outlines the evidence in favor of a model theory of induction. (shrink)

Inferential Role Semantics is often criticized for being incompatible with the platitude that words of different speakers can mean the same thing. While many assume that this platitude can be accommodated by understanding sameness of meaning in terms of similarity of meaning, no worked out proposal has ever been produced for Inferential Role Semantics. I rectify this important omission by giving a detailed structural account of meaning similarity in terms of graph theory. I go on to argue that this account (...) has a number of attractive features, prominent among them that it makes sameness of meaning probabilistically determine co-reference. (shrink)

Experimental restrictionists have challenged philosophers’ reliance on intuitions about thought experiment cases based on experimental findings. According to the expertise defense, only the intuitions of philosophical experts count—yet the bulk of experimental philosophy consists in studies with lay people. In this paper, we argue that direct strategies for assessing the expertise defense are preferable to indirect strategies. A direct argument in support of the expertise defense would have to show: first, that there is a significant difference between expert and lay (...) intuitions; second, that expert intuitions are superior to lay intuitions; and third, that expert intuitions accord with the relevant philosophical consensus. At present, there is only little experimental evidence that bears on these issues. To advance the debate, we conducted two new experiments on intuitions about knowledge with experts and lay people. Our results suggest that the intuitions of epistemological experts are superior in some respects, but they also pose an unexpected challenge to the expertise defense. Most strikingly, we found that even epistemological experts tend to ascribe knowledge in fake-barn-style cases. This suggests that philosophy, as a discipline, might fail to adequately map the intuitions of its expert practitioners onto a disciplinary consensus. (shrink)

We may usefully distinguish between one’s having fallible knowledge and having a fallibilist stance on some of one’s knowledge. A fallibilist stance could include a concessive knowledge-attribution. But it might also include a questioning knowledge-attribution. Attending to the idea of a QKA leads to a distinction between what we may call closed knowledge that p and open knowledge that p. All of this moves us beyond Elgin’s classic tale of the epistemic capacities of Holmes and of Watson, and towards a (...) way of resolving Kripke’s puzzle about dogmatism and knowing. (shrink)

El artículo propone una concepción no individualista de la justifi cación epistémica de las decisiones judiciales. Sugiere que la epistemología jurídica debe reconsiderar su teoría de la justifi cación epistémica con el fi n de dar cuenta de la posibilidad de que juzgadores racionales carezcan de autonomía intelectual. Sostiene que la dependencia epistémica es una de las propiedades que distinguen el razonamiento jurídico sobre los hechos, y que los juzgadores tienen buenas razones para aceptar una proposición sobre la base de (...) la experiencia cognitiva de otras personas. Después de hacer algunas precisiones terminológicas acerca de los conceptos de “testimonio” y “evidencia”, el trabajo explica la estructura de la dependencia epistémica, aborda los debates normativos actuales acerca de la justifi cación epistémica en casos de testimonio, y propone una posición externalista distinta, el antiindividualismo. Al fi nal, se explora una variación sobre el tema, que consiste en la integración de la noción de dependencia epistémica en una teoría de la autoridad en el derecho. (shrink)

The frame problem is the problem of how we selectively apply relevant knowledge to particular situations in order to generate practical solutions. Some philosophers have thought that the frame problem can be used to rule out, or argue in favor of, a particular theory of belief states. But this is a mistake. Sentential theories of belief are no better or worse off with respect to the frame problem than are alternative theories of belief, most notably, the “map” theory of belief.

Four experiments examined the strategies that individuals develop in sentential reasoning. They led to the discovery of five different strategies. According to the theory proposed in the paper, each of the strategies depends on component tactics, which all normal adults possess, and which are based on mental models. Reasoners vary their use of tactics in ways that have no deterministic account. This variation leads different individuals to assemble different strategies, which include the construction of incremental diagrams corresponding to mental models, (...) and the pursuit of the consequences of a single model step by step. Moreover, the difficulty of a problem (i.e., the number of mental models required by the premises) predisposes reasoners towards certain strategies. Likewise, the sentential connectives in the premises also bias reasoners towards certain strategies, e.g., conditional premises tend to elicit reasoning step by step whereas disjunctive premises tend to elicit incremental diagrams.

Among the difficulties that sentential theories of belief face, the problem of clutter asserts that treating beliefs as sentences would make it difficult or impossible to literally fit the number of beliefs possessed by ordinary human cognizers into the mind-brain. I argue that concerns about clutter arise from a misunderstanding of how belief states, whether sentences or not, are causally related. Insofar as a weak computer model of the mind treats information states as virtual states, I explain how the ontology (...) of virtual states seriously mitigates the problem of clutter for sententialism.
