Bayesian Epistemology is a general framework for thinking about agents who have beliefs that come in degrees. Theories in this framework give accounts of rational belief and rational belief change, which share two key features: (i) rational belief states are represented with probability functions, and (ii) rational belief change results from the acquisition of evidence. This dissertation focuses specifically on the second feature. I pose the Evidence Question: What is it to have evidence? Before addressing this question we must have (...) an understanding of Bayesian Epistemology. The first chapter argues that we should understand Bayesian Epistemology as giving us theories that are evaluative and not action-guiding. I reach this verdict after considering the popular ‘ought’-implies-‘can’ objection to Bayesian Epistemology. The second chapter argues that it is important for theories in Bayesian Epistemology to answer the Evidence Question, and distinguishes between internalist and externalist answers. The third and fourth chapters present and defend a specific answer to the Evidence Question. The account is inspired by reliabilist accounts of justification, and attempts to understand what it is to have evidence by appealing solely to considerations of reliability. Chapter 3 explains how to understand reliability, and how the account fits with Bayesian Epistemology, in particular, the requirement that an agent’s evidence receive probability 1. Chapter 4 responds to objections, which maintain that the account gives the wrong verdict in a variety of situations including skeptical scenarios, lottery cases, scientific cases, and cases involving inference. After slight modifications, I argue that my account has the resources to answer the objections. The fifth chapter considers the possibility of losing evidence. I show how my account can model these cases. To do so, however, we require a modification to Conditionalization, the orthodox principle governing belief change. I present such a modification. The sixth and seventh chapters propose a new understanding of Dutch Book Arguments, historically important arguments for Bayesian principles. The proposal shows that the Dutch Book Arguments for implausible principles are defective, while the ones for plausible principles are not. The final chapter is a conclusion. (shrink)

This chapter provides an overview of the issues involved in recent debates about the epistemological relevance of emotions. We first survey some key issues in epistemology and the theory of emotions that inform various assessments of emotions’ potential significance in epistemology. We then distinguish five epistemic functions that have been claimed for emotions: motivational force, salience and relevance, access to facts and beliefs, non-propositional contributions to knowledge and understanding, and epistemic efficiency. We identify two core issues in the discussions about (...) such epistemic functions of emotions: First, even though it is plausible that emotions are involved in epistemic processes, it may be doubted whether they really matter for the normative question of what counts as knowledge or justified belief. Second, some of the epistemic functions claimed for emotions in general may only be attributed to some specifically epistemic emotions, which have been present all along in traditional epistemology, albeit under different labels such as ‘intuitions’.

The dissertation examines the nature and epistemic implications of epistemic source circularity. An argument exhibits this type of circularity when at least one of the premises is produced by a belief source the conclusion says is legitimate, e.g. a track record argument for the legitimacy of sense perception that uses premises produced by sense perception. In chapter one I examine this and several other types of circularity, identifying relevant similarities and differences between them. In chapter two I discuss the differences (...) between internalist and externalist analyses of justification. I examine in detail foundationalist and non-foundationalist versions of internalism, and go on to consider how one might characterize externalism: either negatively, by denying particular internalist theses, or positively, in terms of a theory offering different conditions for justification. I discuss the views of reliabilist foundationalists at length. In chapter three I present the internalist objection to externalism that the latter mistakenly permit one to be justified in believing the conclusion of an epistemic source circular inference. I explain the externalists' response that it is not in virtue of their externalism that they permit epistemic source circularity but rather their foundationalism; thus, internalist foundationalists must permit epistemic source circularity as well. I evaluate the positions of several internalists, most of them explicitly foundationalists, and argue that they too cannot avoid permitting epistemic source circularity. In the final chapter I consider whether such circularity is vicious, even though both internalist and externalist foundationalists permit it. I argue that one can sustain an objection to epistemic source circularity by imposing a non-question-begging requirement on justification and explain how respecting this requirement leads one to a non-foundationalist view. I conclude by considering the objection that question-begging leads to a certain arbitrariness in belief formation that should give the foundationalist pause when it comes to determining, at the beginning of inquiry, which beliefs are justified and which are not. The dissertation is primarily concerned with making clear the possible skeptical and non-skeptical positions one can take towards epistemic source circularity. I do not argue for the truth of a particular metaepistemology. (shrink)

The thesis proposes an account of the means of scientific representation focused on similarity, or more specifically, on the notion of “creative similarity”. I first distinguish between two different questions regarding the problem of representation: the question about the constituents and the question about the means of representation (following Suárez 2003; van Fraassen 2008). I argue that, although similarity is not a good candidate for constituent of representation, it can satisfactorily answer the question about the means of representation if adequately (...) characterized. To motivate this position, I dispute the main arguments offered against similarity as means of representation, namely the arguments from variety, vagueness, and misrepresentation, and contend that similarity plays a central epistemic role in practices of representing in science. The study of the role of similarity in scientific practice, I argue, requires the analysis of the uses of judgments of similarity in the construction of scientific models. I examine the cases of the Mississippi Basin Model and the San Francisco Bay Model to illustrate how judgments of similarity are directly involved in the production of epistemically fruitful models. Informed by the practical investigation developed throughout the thesis, I finally outline what I call the creative similarity account of the means of representation. The notion of “creative similarity” helps to capture the way in which similarity, as means of representation, intervenes in actual practices of representing, namely, in the form of a productive interplay of judgments of similarity and distortions (i.e. idealizations, abstractions, simplifications), which is employed by resourceful agents with the aim of understanding aspects of the natural world.

Traditional accounts of justification can be characterized as trying to analyze justification in such a way that having a justified belief brings with it assurance of truth. The internalist offers a demanding requirement on justification: one's having a justified belief requires that one see what the belief has going for it. Externalists worry that the internalist's narrow conception of justification will lead to unacceptably radical and implausible skepticism. According to the externalist, one need not know what a belief has going (...) for it in order for that belief to be justified. Externalism, though, comes with its own problems. Ernest Sosa has attempted to bridge the divide between internalism and externalism by pairing the strengths of internalism with the strengths of externalism. Sosa distinguishes two kinds of knowledge: animal knowledge that is essentially externalist in character and reflective knowledge that is intended to capture our best intellectual procedure in regards to knowledge. On Sosa's view, one gains reflective knowledge by building upon animal knowledge. As a result, Sosa's view seems to illustrate a bottom-up approach to the analysis of knowledge : reflective knowledge is the result of animal knowledge and some other epistemic factor. My project, in contrast to Sosa's, is to argue that one should start with an account of ideal justification and then proceed by loosening the standards on ideal justification in an effort to develop the possibility of non- ideal kinds of justification. The view that I will develop will adopt Sosa's strategy of distinguishing kinds of knowledge, but will result in a top-down approach to the analysis of justification. Instead of starting with an undemanding standard and layer levels on top, I will start with an ideal standard and strip layers away. I will also argue that my view has some important advantages over Sosa's. Not only does Sosa's view seem to run into many of the problems that threaten externalism, but his view is incapable of offering the kind of assurance that the internalist is after. The view I develop will maintain the internalist's interest in assurance while also providing a response to some of the skeptical problems that have plagued internalists. If my project is successful, then, even if the justification that results in many of the cases I will be exploring is not ideal, we can use these conceptions of justification to help explicate how one might have justified beliefs about a great number of things. The essentially internalist account that I have offered will not only illustrate a serious approach to dealing with skepticism, but it will also capture how many of our commonsensically justified beliefs are in fact justified.

If political decision-making aims at getting a particular result, like identifying just laws or policies that truly promote the common good, then political institutions can also be evaluated in terms of how often they achieve these results. Epistemic defenses of democracy argue that democracies have the upper hand when it comes to truth, identifying the laws and policies that are truly just or conducive to the common good. A number of epistemic democrats claim that democracies have this beneficial connection to (...) truth because of the type of deliberative environment created by democratic political institutions. Democratic political cultures make it easier to exchange and give reasons, ultimately improving the justification that citizens have for their political beliefs. With this improved justification comes a better chance at truth, or so the story goes. In this paper, I show that attempts to forge a connection between justification and truth in epistemology have encountered numerous difficulties, making the case that this causes trouble for deliberative epistemic defenses of democracy as well. If there is no well-defined connection between truth and justification, then increasing the justification that citizens have for their beliefs may not also increase the likelihood that those beliefs are true, revealing a serious flaw in charting a connection between political justification and political truth.

English: In this paper I indicate why I consider 'experimental philosophy' to be good news, though not as good as it could be, and not as all that new.

"Partial realism" is a common position in the contemporary philosophy of science literature. It states that the "essential" elements of empirically successful scientific theories accurately represent corresponding features the world. This thesis makes several novel contributions related to this position. Firstly, it offers a new definition of the concept of “empirical success”, representing a principled merger between the use-novelty and unification accounts. Secondly, it provides a comparative critical analysis of various accounts of which elements are "essential" to the success of (...) a theory, including structural realism and the divide et impera strategy. A novel account of essentialness, entitled the “empirically successful sub-theory "account", is defended. Thirdly, it is argued that the realism/anti-realism debate should put to the side metaphysical questions and focus instead on partial realism's commitment to the continuity of science. Because this commitment lacks metaphysical implications, it is referred to as "deflationary realism". Anti-realists cannot reject deflationary realism as a matter of a priori principle; its overall viability can therefore only be assessed by a careful examination of the history of science. Finally, another consequence of partial realism, named "partial rationalism", is defended. Partial rationalism states that, in cases where several competing theories have been suggested, scientists are rational just in case they accept the essential elements of each of the scientific theories on offer. This novel position subverts the existing literature on scientific "revolutions", as it sometimes demands that scientists devise a synthesis between competing scientific theories, instead of "choosing" only one. The philosophical points defended in this thesis are illustrated and supported by case studies from the history of science, including Fresnel’s wave theory of light, the Copernican revolution, the "neo-Darwinian synthesis" in evolutionary biology, the "prion revolution" in molecular biology, the miasma theory of disease, and the chemical revolution.

An orthodox sceptical hypothesis claims that one’s belief that “I am not a brain-in-a-vat (BIV)” (or any other ordinary anti-sceptical belief) is insensitive. A form of sensitivity-based scepticism, can thus be constructed by combining this orthodox hypothesis with the sensitivity principle and the closure principle. Unlike traditional solutions to the sensitivity-based sceptical problem, this paper will propose a new solution—one which does not reject either closure or sensitivity. Instead, I argue that sceptics’ assumption that one’s ordinary anti-sceptical beliefs are insensitive (...) will give rise to self-contradiction. The orthodox sceptical hypothesis is thus revealed to be incoherent and arbitrary. Given that there is no coherent reason to presuppose our ordinary anti-sceptical beliefs to be insensitive, the argument for sensitivity-based scepticism can thus be blocked at a lower epistemological cost.

One of the important challenges in the philosophy of mathematics is to account for the semantics of sentences that express mathematical propositions while simultaneously explaining our access to their contents. This is Benacerraf’s Dilemma. In this dissertation, I argue that cognitive science furnishes new tools by means of which we can make progress on this problem. The foundation of the solution, I argue, must be an ontologically realist, albeit non-platonist, conception of mathematical reality. The semantic portion of the problem can (...) be addressed by accepting a Chomskyan conception of natural languages and a matching internalist, mentalist and nativist view of semantics. A helpful perspective on the epistemic aspect of the puzzle can be gained by translating Kurt G ̈odel’s neo-Kantian conception of the nature of mathematics and its objects into modern, cognitive terms.

Chapter 3 (Captured in our Cockpits) explains the evolution of consciousness, using value driven decision theory.

The subject of this paper is the epistemology of identity: a general theory of knowledge, evidence and justification for the claim that one thing is identical to another. Although identity figures significantly in our epistemic lives, this is a topic that, to the best of my knowledge, has gone entirely unexplored. Initial attempts to integrate such an epistemology into existing theories of evidence---many of which are tailor-made for contingent propositions---are confounded by the necessity of identity. I defend a restricted form (...) of skepticism according to which the only knowable identity claims are trivial. (shrink)

Starting from the sixties of the past century theory change has become a main concern of philosophy of science. Two of the best known formal accounts of theory change are the post-Popperian theories of verisimilitude (PPV for short) and the AGM theory of belief change (AGM for short). In this paper, we will investigate the conceptual relations between PPV and AGM and, in particular, we will ask whether the AGM rules for theory change are effective means for approaching the truth, (...) i.e., for achieving the cognitive aim of science pointed out by PPV. First, the key ideas of PPV and AGM and their application to a particular kind of propositional theories - the so called "conjunctive propositions" - will be illustrated. Afterwards, we will prove that, as far as conjunctive propositions are concerned, AGM belief change is an effective tool for approaching the truth. (shrink)

Teresa believes in God. Maggie’s wife believes that the Earth is flat, and also that Maggie should be home from work by now. Anouk—a cat—believes it is dinner time. This dissertation is about what believing is: it concerns what, exactly, ordinary people are attributing to Teresa, Maggie’s wife, and Anouk when affirming that they are believers. Part I distinguishes the attitudes of belief that people attribute to each other (and other animals) in ordinary life from the cognitive states of belief (...) theoretically posited by (some) cognitive scientists. Part II defends the view that to have an attitude of belief is to live—to be disposed to act, react, think, and feel—in a pattern that an actual belief attributor identifies with taking the world to be some way. Drawing on scientific, scholarly, and literary sources of evidence, How Beliefs are like Colors provides a framework for research on belief across the humanities and sciences of the mind. (shrink)

How do agents with limited cognitive capacities flourish in informationally impoverished or unexpected circumstances? Aristotle argued that human flourishing emerged from knowing about the world and our place within it. If he is right, then the virtuous processes that produce knowledge, best explain flourishing. Influenced by Aristotle, virtue epistemology defends an analysis of knowledge where beliefs are evaluated for their truth and the intellectual virtue or competences relied on in their creation. However, human flourishing may emerge from how degrees of (...) ignorance are managed in an uncertain world. Perhaps decision-making in the shadow of knowledge best explains human wellbeing—a Bayesian approach? In this dissertation I argue that a hybrid of virtue and Bayesian epistemologies explains human flourishing—what I term homeostatic epistemology. Homeostatic epistemology supposes that an agent has a rational credence p when p is the product of reliable processes aligned with the norms of probability theory; whereas an agent knows that p when a rational credence p is the product of reliable processes such that: 1) p meets some relevant threshold for belief, 2) p coheres with a satisficing set of relevant beliefs and, 3) the relevant set of beliefs is coordinated appropriately to meet the integrated aims of the agent. Homeostatic epistemology recognizes that justificatory relationships between beliefs are constantly changing to combat uncertainties and to take advantage of predictable circumstances. Contrary to holism, justification is built up and broken down across limited sets like the anabolic and catabolic processes that maintain homeostasis in the cells, organs and systems of the body. It is the coordination of choristic sets of reliably produced beliefs that create the greatest flourishing given the limitations inherent in the situated agent. (shrink)

There are two chief tasks which confront the philosophy of scientific method. The first task is to specify the methodology which serves as the objective ground for scientific theory appraisal and acceptance. The second task is to explain how application of this methodology leads to advance toward the aim(s) of science. In other words, the goal of the theory of method is to provide an integrated explanation of both rational scientific theory choice and scientific progress.

The notion of an ideal reasoner has several uses in epistemology. Often, ideal reasoners are used as a parameter of (maximum) rationality for finite reasoners (e.g. humans). However, the notion of an ideal reasoner is normally construed in such a high degree of idealization (e.g. infinite/unbounded memory) that this use is unadvised. In this dissertation, I investigate the conditions under which an ideal reasoner may be used as a parameter of rationality for finite reasoners. In addition, I present and justify (...) the research program of computational epistemology, which investigates the parameter of maximum rationality for finite reasoners using computer simulations.

The purpose of this paper is to explore the question whether and in what sense emotions might be said to provide reasons for actions or to rationalize them. This requires that one have a picture of the causal structure of actions that is sufficiently detailed for one to see how emotions can impinge on the proc-ess of action production. I present a two-tiered model of action explanation and try to exploit this model in a tentative account of the modes of (...) in-volvement of emotions in the explanation of action. In particular, I examine in what sense emotions can be said not just to explain actions, but also to rationalize them. (shrink)

There is a kind of objectivism in epistemology that involves the acceptance of objective epistemic norms. It is generally regarded as harmless. There is another kind of objectivism in epistemology that involves the acceptance of an objectivist account of justification, one that takes the justification of a belief to turn on its accuracy. It is generally regarded as hopeless. It is a strange and unfortunate sociological fact that these attitudes are so prevalent. Objectivism about norms and justification stand or fall (...) together. Justification is simply a matter of conforming to norms. In this essay, I shall make the case for objectivism about justification. (shrink)

In this dissertation, I argue for a new conception of the epistemic condition on moral responsibility.

The following thesis starts from the question «why be moral?» and adresses an action-theoretic strategy for answering this question in the positive by reference to the constitutive natur of actions. In these debates, the epistemology of action has turned into a central issue. The thesis adresses these debates and develops a novel account of the epistemology: an account that may well turn out to provide a ground for the aforementioned constitutivist strategies.

A large portion of philosophy done in the Western analytic tradition attempts to provide conceptual analyses which are tested by examples that elicit intuitions. These intuitions are, in turn, used as evidence either for or against a given analysis. In recent years, there has been much discussion of the uses of intuitions from empirically minded philosophers and psychologists. The basic strategy is to discover empirically how “normal” folks think about certain topics in philosophy. This application of folk intuitions to philosophy (...) branches into roughly two basic approaches. The first is an attempt to show that in given domains, folk intuitions are not very reliable sources of evidence; hence, we have good reason to think that philosophers' intuitions are also not reliable sources of evidence in that domain. The second approach attempts to determine what folk concepts are. Once folk concepts are analyzed, they are then argued to be relevant to philosophical debates. My guiding question for this dissertation is the following one: Why should philosophers care about folk intuitions? One answer is that we should want some philosophical analyses to be grounded in everyday concepts. I argue that there are presently no adequate a priori arguments for the reliability of philosophical intuitions in some philosophically relevant areas. Whether intuitions are reliable enough to ground philosophical analyses is an empirical question. I review four domains where ordinary concepts have been argued to ground philosophical theorizing: (1) epistemology, (2) ethics, (3) free will, and (4) action theory. I argue that the available evidence suggests that we should be skeptical of intuitions in philosophy—but that skepticism does not entail radical skepticism. That is, the empirical studies reveal a wide variety of results which on the surface indicate that intuitions are not reliable (e.g., order effects or framing effects). However, I argue that these seeming instabilities are actually the results of stable differences in different groups of people. Hence, I argue that intuitions are stable in a surprising way—that different groups of people have stable intuitions. This intuition stability, while not the kind of monolithic stability many philosophers might desire, is argued to be sufficient to ground philosophical analyses in these domains. (shrink)

Philosophical conceptual analysis is an experimental method. Focusing on this helps to justify it from the skepticism of experimental philosophers who follow Weinberg, Nichols & Stich. To explore the experimental aspect of philosophical conceptual analysis, I consider a simpler instance of the same activity: everyday linguistic interpretation. I argue that this, too, is experimental in nature. And in both conceptual analysis and linguistic interpretation, the intuitions considered problematic by experimental philosophers are necessary but epistemically irrelevant. They are like variables introduced (...) into mathematical proofs which drop out before the solution. Or better, they are like the hypotheses that drive science, which do not themselves need to be true. In other words, it does not matter whether or not intuitions are accurate as descriptions of the natural kinds that undergird philosophical concepts; the aims of conceptual analysis can still be met.

Would it be possible to have an alternative to the physicalist world-view? If any type of dualism is not an option, I am tempted to consider an integrational world view, which was first claimed by Confucius under the notion of cheng. I would propose an integrational thesis that cheng of an entity is a power to realize the embedded objective of it in the context where it interacts with all others. The notion of compassion may be said to be both (...) dispositional and mental. Then, this notion is one candidate to shed lights on the integrational thesis. The thesis doesn't exclude roles the causal notion has to play in the integrational system. Rather it allows the causal notion in its proper place, not having to exclude other relational notions in the system. What it denies is that the causal relation is all there is among what is there. The notion of compassion is essentialist in two senses. The first is the sense in which Mencius said that compassion is necessary for one to be a human. The second is the sense that compassion is an essentialist disposition. "Compassion" does neither refer to a mental state nor reflect a human relation, but it denotes an abstract property, or a theoretical notion, which can be singled out by a Ramsey sentence. There are many challenges for the integrational thesis to meet. Some of them are how the integrational thesis could allow an essentialism of a kind?, Is there a way for the integrational view of language to meet the requirements of modal semantics?, and so on. The present paper may not able to explain all of these questions but it will try to suggest how to approach toward the task. (shrink)

This paper develops a “Cliffordian” argument for a common epistemic norm governing belief, action, and assertion. The idea is that beliefs are the sorts of things that lead to actions and assertions. What each of us believes influences what we act on and assert, and in turn influences what those around us believe, act on, and assert. Belief, action, and assertion should be held to a common epistemic norm because, otherwise, this system will become contaminated. The paper finishes by drawing (...) out the relativistic implications of the Cliffordian argument. (shrink)

A significant and interesting part of the post-Gettier literature regarding the analysis of propositional knowledge is the attempt to supplement the traditional tripartite analysis by employing a fourth condition regarding the defeasibility of evidence and thus to preclude the counterexamples displayed in Gettier’s original article. My aim in this paper is to critically examine the sort of externalism that accompanies the most promising of the proposed fourth conditions, due to Pollock, in order to offer some fresh insights on this old (...) epistemological issue. I argue that Pollock’s paradigmatic treatment of the matter gives rise to a critical problem with regard to the exact role of the fourth condition and its relation with the onto-semantic or alethic condition of propositional knowledge, to wit, truth. In the light of this discussion, I draw certain conclusions about epistemic externalism and point out some of its theoretical shortcomings. (shrink)

For any normative domain, we can theorize about what is good in that domain. Such theories include utilitarianism, a view about what is good morally. But there are many domains other than the moral; these include the prudential, the aesthetic, and the intellectual or epistemic. In this last domain, it is good to be knowledgeable and bad to ignore evidence, quite apart from the morality, prudence, and aesthetics of these things. This dissertation builds a theory that stands to the epistemic (...) domain as utilitarianism stands to the moral domain. It builds an epistemic value theory. (shrink)

If you put chimpanzees from different communities together you can expect mayhem - they are not keen on treating each other nicely. There is closely related species of apes, however, whose members have countless encounters with unrelated specimen on a daily basis and yet almost all get through the day in one piece - that species is us, homo sapiens. But what makes us get along, most of the time? Morality as such is, perhaps surprisingly, not a mainstream research topic (...) in social psychology. Most textbooks in the field do not even mention the term morality at all (and focus on 'prosociality' instead). This relative lack of 'coverage' might have to do with the difficulty of operationalising 'morality' in a fitting way (more on this below). However, morality certainly is a social phenomenon and therefore the collection of Fargas, Jussim, and Van Lange is certainly a step in the right direction; it offers an extensive overview of the field and is suggestive of the vast potential of studying morality through the lens of social psychology.

En este trabajo se explora una conexión entre el contextualismo y el fiabilismo. El propósito es desarrollar las líneas centrales de un acercamiento contextualista para resolver la crítica internista de que las nociones fiabilistas de justificación y de conocimiento no son adecuadas porque no recogen las intuiciones correspondientes a que un sujeto que está justificado o que sabe es racional y epistemológicamente responsable. Se argumenta que esta crítica y el escepticismo pirrónico comparten un presupuesto común, a saber, la cláusula internista, (...) por lo que, si es posible limitar el alcance de esta cláusula a través del contextualismo distinguiendo dos contextos diferentes, entonces también es posible hacer uso de esta distinción para dar respuesta a la crítica internista al fiabilismo. In this paper, we explore a connection between reliabilism and contextualism. our purpose is to draw up a contextualist approach to solve the critique that the reliabilist notions of justification and knowledge are not satisfactory because there is no room for the intuitions that a subject who is justified or knows is rational and epistemologically responsible. We will argue that this critique and the Pyrrohnian skepticism share the same assumption, viz., the internalist clause. Thus, if it is possible to limit the scope of this clause using contextualism, making a distinction between two different contexts, then it is also possible to use this distinction to offer an answer to the internalist critique to reliabilism.

We present an information theoretic account of models as scientific representations, where scientific models are understood as information carrying artifacts. We propose that the semantics of models should be based on this information coupling of the model to the world. The information theoretic account presents a way of avoiding the need to refer to agents' intentions as constitutive of the semantics of scientific representations, and it provides a naturalistic account of model semantics, which can deal with the problems of asymmetry, (...) relevance and circularity that afflict other currently popular naturalistic proposals.

In Science, Truth, and Democracy (2001a), Kitcher moderates the strongest ontological realist thesis he defended in The Advancement of Science (1993a), with the aim of making compatible the correspondence theory of truth with conceptual relativity. However, it is not clear that both things could be harmonized. If our knowledge of the world is mediated by our categories and concepts; if the selection of these categories and concepts may vary according to our interests, and they are not the consequence of the (...) existence of certain supposed natural kinds or some intrinsic structure of the world, it is very problematic to establish what our true statements correspond to. This paper analyzes the transformation in Kitcher's realism and expounds the main difficulties in this project. Finally, a modality of moderate ontological realism will be proposed that, despite of keeping the sprit of the conceptual relativity, is strong enough to support the correspondence theory of truth.

A central tenet of cognitivism is that knowing how is to be explained in terms of tacitly knowing that a theory is true. By critically examining canonical anti-behaviorist arguments and contemporary appeals to tacit knowledge, I have devised a more explicit characterization in which tacitly known theories must act as justifiers for claims that the tacit knower is capable of explicitly endorsing. In this manner the new account is specifically tied to verbal behavior. In addition, if the analysis is correct (...) then it follows that the scope and nature of cognitivist appeals to tacit knowledge are largely mistaken. (shrink)

Over the past few decades, reasoning and rationality have been the focus of enormous interdisciplinary attention, attracting interest from philosophers, psychologists, economists, statisticians and anthropologists, among others. The widespread interest in the topic reflects the central status of reasoning in human affairs. But it also suggests that there are many different though related projects and tasks which need to be addressed if we are to attain a comprehensive understanding of reasoning.

Chapter 2 of Mill’s On Liberty is reconstructed as a complex argument for freedom of discussion; it consists of three subarguments, each possessing illative and dialectical components. The illative component is this: freedom of discussion is desirable because it enables us to determine whether an opinion is true, whereas its denial amounts to an assumption of infallibility; it improves our understanding and appreciation of the supporting reasons of true opinions, and our understanding and appreciation of their practical or emotional meaning; (...) it enables us to understand and appreciate every side of the truth, given that opinions tend to be partly true and partly false and people tend to be one-sided. The dialectical component consists of replies to ten objections, five in the first subargument, three in the second, one in the third, and one general. An analysis of Mill’s argument suggests that it is a contribution to argumentation theory; it advocates and practices a dialectical approach; its reconstruction and analysis are a contribution to argumentation theory; and it raises in a striking manner the issue of the relationship between epistemology and argumentation theory.

Traditional philosophy has been under attack from several quarters in recent years. The traditional philosopher views philosophy as an armchair discipline relying, for the most part, on reason and reflection. Some philosophers doubt the legitimacy of this type of inquiry. Their arguments usually occur along two dimensions. Some argue that the primary data source for the armchair philosopher--intuition--does not provide evidence for philosophical theories. Others argue that conceptual analysis, which is the preferred method of inquiry for armchair philosophers, can't yield (...) the results the philosopher is looking for, since concepts like 'knowledge' or 'free-will' vary from culture to culture or even between persons within a culture. Finally, some philosophers argue that we should abandon the armchair program because philosophy should be an empirical enterprise continuous with the sciences. I argue that attempts to undermine intuition fail and that one can justify the evidential status of intuition in a non-question begging way. I then argue that attacks on the belief in shared concepts do not succeed because they often conflate the nature of scientific objects with those of interest to the philosopher. However, if concepts do vary from culture to culture, I show that the philosopher need not abandon the armchair. She can still do conceptual analysis but it will be only the entry point into the philosophical dialogue. I apply this approach to epistemology arguing that the central epistemic questions ought to be the existential and the normative. This approach helps to vindicate epistemic internalism. (shrink)

The purpose of this paper is to present a formal model of social net- works suitable for studying questions in social epistemology. We show how to use this model, in conjunction with a computer program for simulating groups of inquirers, to draw conclusions about the epistemological prop- erties of different social practices. This furnishes us with the beginnings of a systematic research program in social epistemology, from which to approach problems pertaining to epistemic value, optimal organization, and the dynamics of (...) multi-agent inquiry.
