This paper argues that Pascal's formulation of his famous wager argument licenses an inference about God's nature that ultimately vitiates the claim that wagering for God is in one's rational self-interest. In particular, it is argued that if we accept Pascal's premises, then we can infer that the god for whom Pascal encourages us to wager is irrational. But if God is irrational, then the prudentially rational course of action is to refrain from wagering for him.

The justificatory force of empirical reasoning always depends upon the existence of some synthetic, a priori justification. The reasoner must begin with justified, substantive constraints on both the prior probability of the conclusion and certain conditional probabilities; otherwise, all possible degrees of belief in the conclusion are left open given the premises. Such constraints cannot in general be empirically justified, on pain of infinite regress. Nor does subjective Bayesianism offer a way out for the empiricist. Despite often-cited convergence theorems, subjective (...) Bayesians cannot hold that any empirical hypothesis is ever objectively justified in the relevant sense. Rationalism is thus the only alternative to an implausible skepticism. (shrink)

I defend the 'Repugnant' Conclusion that for any possible population of happy people, a population containing a sufficient number of people with lives barely worth living would be better. Four lines of argument converge on this conclusion, and the conclusion has a simple, natural theoretical explanation. The opposition to the Repugnant Conclusion rests on a bare appeal to intuition. This intuition is open to charges of being influenced by multiple distorting factors. Several theories of population ethics have been devised to (...) avoid the Repugnant Conclusion, but each generates even more counterintuitive consequences. The intuition opposing the Repugnant Conclusion is thus among the best candidates for an intuition that should be revised. (shrink)

While feminist philosophy has had much to say on the topic of reason, little has been done to develop a specifically feminist account of the concept. I argue for a virtue account of mind grounded in contemporary approaches to rationality. The evolutionary stance adopted within most contemporary theories of mind implicitly entails a rejection of central elements of Cartesianism. As a result, many accounts of rationality are anti-modern is precisely the sorts of ways that feminists demand. I maintain that a (...) virtue account of rationality can provide a satisfactory answer to Benhabib’s question in Situating of the Self: what concept of reason are we willing to defend? (shrink)

Anyone who has ever lived with roommates understands the Hobbesian state of nature implicitly. People sharing accommodations quickly discover that buying groceries, doing the dishes, sweeping the floor, and a thousand other household tasks, are all prisoner's dilemmas waiting to happen. For instance, if food is purchased communally, it gives everyone an incentive to overconsume. Individuals also have an incentive to buy expensive items that the others are unlikely to want. As a result, everyone's food bill will be higher than (...) it would be if everyone did their own shopping. Things are not much better when it comes to other aspects of household organization. Cleaning is a common sticking point. Once there are a certain number of people living in a house, cleanliness becomes a quasi-public good. If everyone ‘pitched in’ to clean up, then everyone would be happier. But there is a free-rider incentive—before cleaning, it's best to wait around a bit to see if someone else will do it. As a result, the dishes will stack up in the sink, the carpet will get grungy, and so on. (shrink)

Zhuangzi and Hui Shi's discussion about whether Zhuangzi knows 'fish's happiness' is a Daoist staple. The interpretations, however, portray it as humorous miscommunication between a mystic and a logician. I argue for a fine inferential analysis that explains the argument in a way that informs Zhuangzi philosophical lament at Hui Shi's passing. It also reverses the dominant image of the two thinkers. Zhuangzi emerges as the superior dialectician, the clearer, more analytic epistemologist. Hui Shi's arguments betray his tendency (manifest elsewhere) (...) to misstate the conclusions of their shared relativism leading him but not Zhuangzi to intuitive mysticism. (shrink)

The typical function of goals is to regulate action in a way that furthers goal achievement. Goals are typically set on the assumption that they will help bring the agent closer to the desired state of affairs. However, sometimes endorsement of a goal, or the processes by which the goal is set, can obstruct its achievement. When this happens, the goal is self-defeating. Self-defeating goals are common in both private and social decision-making but have not received much attention by decision (...) theorists. In this paper, we investigate different variants of three major types of self-defeating mechanisms: The goal can be an obstacle to its own fulfilment, goal-setting activities can impede goal achievement, and disclosure of the goal can interfere with its attainment. Different strategies against self-defeasance are tentatively explored, and their efficiency against different types of self-defeasance is investigated. (shrink)

This paper examines methodological issues raised by revealed preference theory in economics: particularly contemporary revealed preference theory. The paper has three goals. First, to make the case that revealed preference theory is a broad research program in choice theory—not a single theory—and understanding this diversity is essential to any methodological analysis of the program. Second, to explore some of the existing criticisms of revealed preference theory in a way that emphasizes how the effectiveness of the critique depends on the particular (...) version of revealed preference under consideration. Finally, three additional criticisms are presented that are aimed specifically at contemporary revealed preference theory. (shrink)

Relatively little contemporary philosophy of education employs economic concepts directly. Even where issues such as marketisation of education are discussed there may be little clarification of underlying concepts. The paper argues that while much contemporary economic thinking on education may be philosophically naive, it is also the case that philosophy of education can productively engage with particular economic insights and perspectives. The paper examines particular conceptualisations of ‘economics’ and ‘the market’, drawing upon these to consider aspects of an issue that (...) is significant for the philosophy of education: human becoming. An example, the notion of ‘wellbeing’ is briefly discussed. (shrink)

The presence of intelligence and rationality in Artificial Intelligence and the Internet requires a new context of analysis in which Herbert Simon’s approach to the sciences of the artificial is surpassed in order to grasp the role of information in our contemporary setting. This new framework requires taking into account some relevant aspects. In the historical endeavor of building up AI and the Internet, minds and machines have interacted over the years and in many ways through the interrelation between scientific (...) creativity and technological innovation. Philosophically, minds and machines can have epistemological, methodological and ontological differences, which are based on the distinct configuration of human intelligence and artificial intelligence. Their comparison with rationality and its various forms is particularly relevant. Scientifically, AI and the Internet belong to the sciences of the artificial, because they work on designs that search for specific aims, following selected processes in order to achieve expected results. Technologically, AI and the Internet require the support of information and communication technologies. These have an instrumental role regarding the existence of AI and the Internet. Also ICT shape their diverse forms of configuration over the years.Within this framework, this paper offers a new context of analysis that goes beyond Simon’s and follows four main steps: the interaction between scientific creativity and technological innovation as the philosophico-methodological setting for Artificial Intelligence and the Internet; artificial intelligence and human intelligence as epistemological basis for machines and minds, where the differences between artificial intelligence and human intelligence are made explicit and the analysis of minds and machines is made from the perspective of rationality ; intention and its difference with design of machine learning are considered to distinguish human intelligence from artificial intelligence; and the internal and external aspects of artificial designs in contemporary society are considered through the perspective of rationality, which leads to the transition from intelligence to rationality in the Internet as well as to the historicity of information.

Normative theories can be useful in developing descriptive theories, as when normative subjective expected utility theory is used to develop descriptive rational choice theory and behavioral game theory. “Ought” questions are also the essence of theories of moral reasoning, a domain of higher mental processing that could not survive without normative considerations.

The various behavioral disciplines model human behavior in distinct and incompatible ways. Yet, recent theoretical and empirical developments have created the conditions for rendering coherent the areas of overlap of the various behavioral disciplines. The analytical tools deployed in this task incorporate core principles from several behavioral disciplines. The proposed framework recognizes evolutionary theory, covering both genetic and cultural evolution, as the integrating principle of behavioral science. Moreover, if decision theory and game theory are broadened to encompass other-regarding preferences, they (...) become capable of modeling all aspects of decision making, including those normally considered “psychological,” “sociological,” or “anthropological.” The mind as a decision-making organ then becomes the organizing principle of psychology.

The paper shows why and how an empirical study of fast-and-frugal heuristics can provide norms of good reasoning, and thus how (and how far) rationality can be naturalized. We explain the heuristics that humans often rely on in solving problems, for example, choosing investment strategies or apartments, placing bets in sports, or making library searches. We then show that heuristics can lead to judgments that are as accurate as or even more accurate than strategies that use more information and computation, (...) including optimization methods. A standard way to defend the use of heuristics is by reference to accuracy-effort trade-offs. We take a different route, emphasizing ecological rationality (the relationship between cognitive heuristics and environment), and argue that in uncertain environments, more information and computation are not always better (the “less-can-be-more” doctrine). The resulting naturalism about rationality is thus normative because it not only describes what heuristics people use, but also in which specific environments one should rely on a heuristic in order to make better inferences. While we desist from claiming that the scope of ecological rationality is unlimited, we think it is of wide practical use. (shrink)

From Mill to, most recently, Bryan Caplan, political and economic elites have been seen as the solution to the public’s ignorance and incompetence. In order to show that elites are actually more competent than the public, however, we would have to find out what type of knowledge is necessary to enact good public policy. The empirical evidence shows that economic experts have a slight advantage over the general public in knowledge of how to achieve policy goals. But, contrary to Caplan, (...) the evidence indicates that economists don’t possess significant predictive knowledge, and that general economic laws are of little help in predicting the magnitude of the effects of a specific policy in a multi‐variable, complex world. When we adopt a more complex understanding of the reasons behind policy choice, and consider rules and principles in addition to goal pursuit, the slight edge of economic experts evaporates.

Though we are in broad agreement with much of Elqayam & Evans' (E&E's) position, we criticize two aspects of their argument. First, rejecting normativism is unlikely to yield the benefits that E&E seek. Second, their conception of rational norms is overly restrictive and, as a consequence, their arguments at most challenge a relatively restrictive version of normativism.

Recent advances in artificial intelligence offer many beneficial prospects. However, concerns have been raised about the opacity of decisions made by these systems, some of which have turned out to be biased in various ways. This article makes a contribution to a growing body of literature on how to make systems for automated decision-making more transparent, explainable, and fair by drawing attention to and further elaborating a distinction first made by Nozick between first-level bias in the application of standards and (...) second-level bias in the choice of standards, as well as a second distinction between discrimination and arbitrariness. Applying the typology developed, a number of illuminating observations are made. First, it is observed that some reported bias in automated decision-making is first-level arbitrariness, which can be alleviated by explainability techniques. However, such techniques have only a limited potential to alleviate first-level discrimination. Second, it is argued that second-level arbitrariness is probably quite common in automated decision-making. In contrast to first-level arbitrariness, however, second-level arbitrariness is not straightforward to detect automatically. Third, the prospects for alleviating arbitrariness are discussed. It is argued that detecting and alleviating second-level arbitrariness is a profound problem because there are many contrasting and sometimes conflicting standards from which to choose, and even when we make intentional efforts to choose standards for good reasons, some second-level arbitrariness remains.

In this paper, the author develops an instrument for the rational reconstruction of argumentation in which a judicial decision is justified by referring to the consequences in relation to the purpose of the rule. The instrument is developed by integrating insights from legal theory and legal philosophy about the function and use of arguments from consequences in relation to the purpose of a rule into a pragma-dialectical framework. Then, by applying the instrument to the analysis of examples from legal practice, (...) it is demonstrated that the instrument can offer a heuristic and critical tool for the analysis and evaluation of legal argumentation that can ‘bridge’ the gap between more abstract discussions of forms of legal argumentation on the one hand, and legal arguments as they occur in actual legal practice on the other hand.

Evidentialism is the thesis that epistemic justification for belief supervenes on evidential support. However, we claim there are cases in which, even though two subjects have the same evidential support for a proposition, only one of them is justified. What make the difference are pragmatic factors, factors having to do with our cares and concerns. Our argument against evidentialism is not based on intuitions about particular cases. Rather, we aim to provide a theoretical basis for rejecting evidentialism by defending a (...) “pragmatic” necessary condition on epistemic justification. We argue for the following necessary condition for justification: S is justified in believing that p only if S is rational to prefer (and, hence, act) as if p. In light of this necessary condition, the price of evidentialism is skepticism, or something close to it. (shrink)

What is the relationship between inquiry and epistemology? Are epistemic norms the norms that guide us as inquirers—as agents in the pursuit of knowledge and understanding? Recently, there has been growing support for what I, following Friedman (Philosophical Review 129(4):501–536, 2020), will call the zetetic turn in epistemology, the view that all epistemic norms are norms of inquiry. This paper investigates the prospects of an inquiry-centered approach to epistemology and develops several motivations for resisting it. First, I argue that the (...) norms of inquiry are most plausibly seen as practical, not as distinctively epistemic. Second, I argue that a zetetically-grounded epistemology is unable to properly account for the rationality of belief. It fails to account for cases where intuitively irrational beliefs promote inquiry, or where intuitively rational beliefs are zetetically useless or counterproductive to inquiry. The main upshot is this: there must be a source of epistemic normativity that isn’t ultimately zetetic. (shrink)

ABSTRACTHumans are cognitive misers because their basic tendency is to default to processing mechanisms of low computational expense. Such a tendency leads to suboptimal outcomes in certain types of hostile environments. The theoretical inferences made from correct and incorrect responding on heuristics and biases tasks have been overly simplified, however. The framework developed here traces the complexities inherent in these tasks by identifying five processing states that are possible in most heuristics and biases tasks. The framework also identifies three possible (...) processing defects: inadequately learned mindware; failure to detect the necessity of overriding the miserly response; and failure to sustain the override process once initiated. An important insight gained from using the framework is that degree of mindware instantiation is strongly related to the probability of successful detection and override. Thus, errors on such tasks cannot be unambiguously attributed to miserly processing – and corre... (shrink)

We propose a critique of normativism, defined as the idea that human thinking reflects a normative system against which it should be measured and judged. We analyze the methodological problems associated with normativism, proposing that it invites the controversial “is-ought” inference, much contested in the philosophical literature. This problem is triggered when there are competing normative accounts (the arbitration problem), as empirical evidence can help arbitrate between descriptive theories, but not between normative systems. Drawing on linguistics as a model, we (...) propose that a clear distinction between normative systems and competence theories is essential, arguing that equating them invites an “is-ought” inference: to wit, supporting normative “ought” theories with empirical “is” evidence. We analyze in detail two research programmes with normativist features – Oaksford and Chater’s rational analysis and Stanovich and West’s individual differences approach – demonstrating how, in each case, equating norm and competence leads to an is-ought inference. Normativism triggers a host of research biases in the psychology of reasoning and decision making: focusing on untrained participants and novel problems, analyzing psychological processes in terms of their normative correlates, and neglecting philosophically significant paradigms when they do not supply clear standards for normative judgement. For example, in a dual-process framework, normativism can lead to a fallacious “ought-is” inference, in which normative responses are taken as diagnostic of analytic reasoning. We propose that little can be gained from normativism that cannot be achieved by descriptivist computational-level analysis, illustrating our position with Hypothetical Thinking Theory and the theory of the suppositional conditional. We conclude that descriptivism is a viable option, and that theories of higher mental processing would be better off freed from normative considerations. (shrink)

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

Are epistemic reasons merely a species of instrumental practical reasons, making epistemic rationality a specialized form of instrumental practical rationality? Or are epistemic reasons importantly different in kind? Despite the attractions of the former view, Kelly (2003) argues quite compellingly that epistemic rationality cannot be merely a matter of taking effective means to one’s epistemic ends. I argue here that Kelly’s objections can be sidestepped if we understand epistemic reasons as instrumental reasons that arise in light of the aims held (...) by social collectives of which we are members, rather than being fixed by our own individual goals. This social version of epistemic instrumentalism would not be subject to counterexamples that point to the failure of individual people to possess desires or goals that would account for all of the epistemic reasons we find it natural to attribute to them. I conclude by comparing the proposed view to the alternative version of instrumentalism defended by Kornblith (1993). I argue that the social view I sketch here has one noteworthy advantage. It better accounts for the intuitive distinctness of our practical and epistemic reasons for belief in cases where flouting epistemic norms would better help us to achieve our own individual goals.

Recently, evidentialists have argued that only they can explain transparency--the psychological phenomena wherein the question of doxastic deliberation of whether to believe p immediately gives way to the question of whether p--and thus that pragmatism about epistemic reasons is false. In this paper, we provide a defense of pragmatism. We depart from previous defenses of pragmatism which argue against the evidentialist explanation of transparency or the fact of transparency itself, by instead arguing that the pragmatist can provide a sound explanation (...) of transparency while maintaining her distinctive view of epistemic reasons. We do so by putting forth an evolutionary debunking explanation of doxastic deliberation. Since both the evidentialist and pragmatist have sound explanatory accounts of transparency, we argue that transparency should not be appealed to when trying to adjudicate the debate between evidentialists and pragmatists, but rather must be decided on other grounds.

Many philosophers are convinced that rationality dictates that one’s overall set of intentions be consistent. The starting point and inspiration for our study is Bratman’s planning theory of intentions. According to this theory, one needs to appeal to the fulfilment of characteristic planning roles to justify norms that apply to our intentions. Our main objective is to demonstrate that one can be rational despite having mutually inconsistent intentions. Conversely, it is also shown that one can be irrational despite having a (...) consistent overall set of intentions. To overcome this paradox, we argue that it is essential for a successful planning system that one’s intentions are practically consistent rather than being consistent or applying an aggregation procedure. Our arguments suggest that a new type of norm is needed: whereas the consistency requirement focuses on rendering the contents of one’s intentions consistent, our new practical consistency requirement demands that one’s intentions be able to simultaneously and unconditionally guide one’s action. We observe that for intentions that conform to the ‘own-action condition’, the practical consistency requirement is equivalent to the traditional consistency requirement. This implies that the consistency requirement only needs to be amended in scenarios of choice under uncertainty. (shrink)

Andy Egan has presented a dilemma for decision theory. As is well known, Newcomb cases appear to undermine the case for evidential decision theory. However, Egan has come up with a new scenario which poses difficulties for causal decision theory. I offer a simple solution to this dilemma in terms of a modified EDT. I propose an epistemological test: take some feature which is relevant to your evaluation of the scenarios under consideration, evidentially correlated with the actions under consideration albeit, (...) causally independent of them. Hold this feature fixed as a hypothesis. The test shows that, in Newcomb cases, EDT would mislead the agent. Where the test shows EDT to be misleading, I propose to use fictive conditional credences in the EDT-formula under the constraint that they are set to equal values. I then discuss Huw Price’s defence of EDT as an alternative to my diagnosis. I argue that my solution also applies if one accepts the main premisses of Price’s argument. I close with applying my solution to Nozick’s original Newcomb problem. (shrink)

This paper aims to solve a puzzle for instrumental conceptions of epistemic normativity. The puzzle is this: if the usefulness of epistemic norms explains their normative grip on us, why does it seem improper to violate these norms even when doing so would benefit us? To solve this puzzle, we argue that epistemic instrumentalists must adopt a more social approach to normativity. In particular, they should not account for the nature of epistemic normativity by appealing to the goals of individual (...) agents. Rather, they should appeal to norms or rules of inquiry that serve our collective goals. We argue that epistemic normativity grows out of our need to promote a deep kind of coordination in our basic epistemic practices. By subscribing to an appropriate system of norms, we can coordinate epistemic rule-following across the community. This makes testimony more trustworthy and reliable. This account not only solves a puzzle about epistemic instrumentalism but also sheds new light on the foundations of normativity and emphasizes the need for a truly social epistemology. (shrink)

Defined narrowly, epistemology is the study of knowledge and justified belief. As the study of knowledge, epistemology is concerned with the following questions: What are the necessary and sufficient conditions of knowledge? What are its sources? What is its structure, and what are its limits? As the study of justified belief, epistemology aims to answer questions such as: How we are to understand the concept of justification? What makes justified beliefs justified? Is justification internal or external to one's own mind? (...) Understood more broadly, epistemology is about issues having to do with the creation and dissemination of knowledge in particular areas of inquiry. This article will provide a systematic overview of the problems that the questions above raise and focus in some depth on issues relating to the structure and the limits of knowledge and justification.

According to the thesis of pragmatic encroachment, practical circumstances can affect whether someone is in a position to know or rationally believe a proposition. For example, whether it is epistemically rational for a person to believe that the bank will be open on Saturdays, can depend not only on the strength of the person’s evidence, but also on how practically important it is for the person not to be wrong about the bank being open on Saturdays. In recent years, philosophers (...) have argued that moral considerations can also affect the epistemic rationality of belief, thus giving rise to moral encroachment. In previous work (Steglich-Petersen, forthcoming a), I have developed an explanation of pragmatic encroachment grounded in an instrumentalist theory of epistemic reasons. Here, I argue that this explanation extends to moral encroachment as well, including so-called “radical” moral encroachment. I also show how this explanation dispels the worry raised by Gerken (2019), that pragmatic encroachment might give rise to morally adverse consequences in the form of epistemic injustice. (shrink)

I begin with a rather unpromising dispute that Nozick once had with Ian Hacking in the pages of the London Review of Books, in which both vied with one another in their enthusiasm to repudiate the thesis that some human people or peoples are closer than others to animality. I shall attempt to show that one can build, on the basis of Nozick’s discussion of rationality, a defense of the view that the capacity tor language places human rationality out of (...) reach of a comparison with animals. The difference rests, paradoxically, on the human capacity tor irratianality. Irrationality depends on the capacity tor language, which allows the detachment of explicit thoughts from their underlying dynamic implementation; these, in turn, condition the essential disputability of principles of rationality. That is what places every human potentially -- if not actually -- on the other side of an unbridgeable gulf that separates us from other animals. (shrink)

Intrinsic value has traditionally been thought to lie at the heart of ethics. Philosophers use a number of terms to refer to such value. The intrinsic value of something is said to be the value that that thing has “in itself,” or “for its own sake,” or “as such,” or “in its own right.” Extrinsic value is value that is not intrinsic.

David Gauthier in his article, Maximization constrained: the rationality of cooperation, tries to defend of the joint strategy in situations which no outcome is both equilibrium and optimal. Prisoner’s Dilemma is the most familiar example of these situations. He first starts with some quotes by Hobbes in Leviathan; Hobbes, in chapter 15 discusses an objection by someone is called Foole, and then will reject his view. In response to Foole, Hobbes presents two strategies (i.e. joint and individual) and two kinds (...) of agents in such problems including Prisoner’s Dilemma – i.e. straightforward maximizer (SM) and constrained maximizer(CM). Then he considers two arguments respectively for SM and CM, and he will show that why in an ideal and transparent situation, the first argument fails and the second one would be the only valid argument. likewise, in the following part of his article, he considers more realistic situations with translucency and he concludes that under some conditions, joint strategy would be still the rational decision.

In this calculation he goes beyond the standard principle of maximizing expected utility and would try to put forth less ideal and more realistic principles that fit (...) the decision situation in the real world.

We often treat our basic, unmotivated desires as reason-giving: you’re thirsty and take yourself to have a reason to walk to the drinking fountain; you care intrinsically about your young daughter and take yourself to have a reason to feed and clothe her. We think these desires generate normative practical reasons. But are there basic desires that don’t? It might seem so, for we sometimes find ourselves impelled to do some very strange, and some very awful, things. For example, would (...) a loving mother with a violent impulse thereby come to have a reason to harm her beloved child? Let’s grant, for the sake of argument, that there are basic desires, such as the mother’s, that fail to generate reasons. Can a subjectivist, a theorist in the Humean tradition, accept this thesis? Against the historical grain, I argue yes. I frame my discussion in terms of solving a puzzle in Harry Frankfurt’s subjectivist theory of rational agency and appeal to the concept of a personal ideal to reveal how a subjectivist, a follower of Hume, can countenance the existence of “rationally impotent basic desires.”.

According to Allen Wood’s “procedural principle” we should believe only that which can be justified by evidence, and nothing more. He argues that holding beliefs which are not justified by evidence diminishes our self-respect and corrupts us, both individually and collectively. Wood’s normative and descriptive views as regards belief are of a piece with the received view which holds that beliefs aim at the truth. This view I refer to as the Truth-Tracking View (TTV). I first present a modest version (...) of TTV, one which is sensitive to standard criticisms and one which is fully consistent with the procedural principle. I then raise some doubts about TTV by considering both anecdotal cases and empirical studies. These studies suggest that certain types of belief are designed to aim away from truth, in limited, carefully calibrated ways. Moreover, it seems to be the case that selectively aiming away from the truth is important for human well-being and performance. Beliefs that are designed to aim away I dub “Tertullian” beliefs (t-beliefs). I then limn the distinguishing characteristics of t-belief and proceed to evaluate the procedural principle in light of the evidence which suggests that t-belief plays an important role in our cognitive economy. Next I argue that t-beliefs might be essential to the maintenance of self-respect and that they do not corrupt in the way that Wood claims. Finally, I argue that the fate of Wood’s procedural principle will be determined by the results of further empirical research— sociological, psychological, and neuroscientific. (shrink)

En el presente trabajo se realiza una exposición breve del punto de vista filosófico de la teoría de la decisión, profundizando específicamente en el trabajo que propone David Lewis al respecto.

In particular cases like Newcomb’s Paradox, non causal decision theories would be insufficient. I will show some basic notions of decision analysis, in order to explain in detail some aspects of Newcomb’s Paradox. Finally, the fundamental theses of Lewis’s Theory and some possible objections are presented. (shrink)

The central problem of the dissertation concerns the possibility of a distinction between truth-evaluable and non-truth-evaluable utterances of a natural language. The class of truth-evaluable utterances includes assertions, con. ectures and other kinds of speech act susceptible of truth evaluation. The class of non-truth-evaluable utterances includes commands, exhortations, wishes i.e. utterances not evaluated as being true or false. The problem is placed in the context of radical interpretation theory and it shown that it is a substantial problem of Davidson‘s early (...) theory of radical interpret at ion. I consider the possibility of distinguishing between locutionary and illocutionary act in uttering a sentence and its significance in the present project. I discuss the suggestion that the mood of the verb of the sentence signifies the required distinction between truth-evaluable utterances and non-truth-evaluable ones. I argue that no criterion for the distinction based on the mood of the verb is adequate. The solution that I propose to the problem of classifylng truth-evaluable utterances appeals to mental states. The view that grounds this line of inquiry is that the truth-evaluability of an utterance is a characteristic of it exclusively relevant to the doxastic dimension of the speaker’s mind. I discuss the constraints that the nature of radical interpretation puts upon the way we construe the notion of belief. I propose that a possible classification of mental states into doxastic and non-doxastic that would result in a classification of utterances into truth-evaluable and non-truthevaluable ones can be given by an elaborated version of a decision theoretic scheme. I suggest that a decision theoretic scheme based on a decision theory that, like Savage’s theory, grants independence axioms is a better candidate to offer a solution to the central problem of the dissertation than a scheme based on a non- standard decision theory such as Richard Jeffrey’s. I conclude by showing that the proposal I make satisfies the constraints I have considered and that it can be accommodated by a radical interpretation theory. (shrink)

This paper discusses the epistemic status of biology from the standpoint of the systemic approach to living systems based on the notion of biological autonomy. This approach aims to provide an understanding of the distinctive character of biological systems and this paper analyses its theoretical and epistemological dimensions. The paper argues that, considered from this perspective, biological systems are examples of emergent phenomena, that the biological domain exhibits special features with respect to other domains, and that biology as a discipline (...) employs some core concepts, such as teleology, function, regulation among others, that are irreducible to those employed in physics and chemistry. It addresses the claim made by Jacques Monod that biology as a science is marginal. It argues that biology is general insofar as it constitutes a paradigmatic example of complexity science, both in terms of how it defines the theoretical object of study and of the epistemology and heuristics employed. As such, biology may provide lessons that can be applied more widely to develop an epistemology of complex systems. (shrink)

Why conduct research concerning human genome or proving the existence of Higgs particle? What makes these problems significant or worthy of investigation? In recent epistemological discussions one can find at least two conceptions of the problem of epistemic significance: research question or cognitive problem can be practically significant or intrinsically epistemically significant, in a way that depends on the consideration whether reasons that support the significance of the problem are practical or epistemic. In this paper I am dealing with the (...) question of the possibility of determining the significance of the problem from the purely epistemic perspective. In that regard I argue that (under suitable interpretation of the problem of epistemic significance) there are no pure epistemic reasons that could determine the importance of the cognitive problem. The argument is based on three objections: (1) epistemic duty is unjustifiably identified with epistemic justification, (2) the dependence of epistemic reasons on conceputal schemes is not taken into consideration, and (3) the infinite justificatory potential of evidence is being disregarded.

The topic of this study is to what extent standards of rational inquiry can be rationally criticized and revised. It is argued that it is rational to treat all such standards as open to criticism and revision. Arguments to the effect that we are fallible with regard to all standards of rational inquiry are presented. Standards cannot be ultimately justified and with certainty established either as adequate or as inescapable presuppositions. Apel's attempt to give ultimate justifications of certain moral and (...) logical rules is examined and criticized. Special attention is given to our fallibility with regard to logical inference rules. The idea that certain logical rules cannot be put into question because any critical argument presupposes them is criticized. It has been claimed that there must be some basic standards which are such that they cannot be rationally evaluated and hence are rationally unrevisable. This is called "the unrevisability thesis". Related to this thesis is the normative policy according to which rationality requires that some standards be treated as unrevisable, the unrevisability policy. Two arguments that have been used to defend the unrevisability thesis and policy are examined and criticized. The conclusion is that we are not forced to accept either the thesis or the policy. The negation of the unrevisability policy is the revisability policy, according to which it is rational to treat all standards as open to rational criticism and revision. Objections that have been directed against the revisability policy are discussed and criticized. According to the objections, the revisability policy leads to rationality relativism. These objections are refuted, and it is argued that it is, on the contrary, rational to adopt the revisability policy and treat all standards of rational inquiry as criticizable and revisable. It is proposed that the rational change of standards should be viewed as a bootstrap process. General features of a bootstrap view of rational change of standards are presented, and it is argued that it is impossible to formulate a real theory of bootstrapping. Two models of standard change are presented and discussed: Laudan's reticulated model of scientific rationality and Briskman's bootstrap theory. It is claimed that in spite of defects and limitations, these models contribute to a richer understanding of bootstrapping. The fallibility and revisability of standards of rational inquiry have consequences for how the normativity of rationality should be understood. The book ends with an account of how the rationality of cognitive actions is related to the idea of the adequacy of standards. A distinction between absolute and standard-relative rationality is made, and it is argued that what an inquiring agent rationally ought to do coincides with what it is standard-relatively rational for him to do. It is shown that this view of rationality of inquiry is nevertheless inconsistent with rationality relativism, and that it is compatible with an objectivistic view of rationality. (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)

Este artículo discute varios modos de entender la racionalidad de la ciencia como racionalidad práctica. En primer lugar, rechaza los modelos instrumentalistas de la racionalidad científica, porque no pueden mostrar la independencia y la bondad de fines definidos para la ciencia, en relación con los cuales se establece la fuerza normativa de las razones. La errónea identificación de fines y valores es lo que provoca numerosas confusiones en este terreno. Se critica, en segundo lugar, un modelo de racionalidad práctica basado (...) en el dominio de saberes tácitos y habilidades. Cualquiera de los modelos propuestos ha de acomodarse a tres restricciones sobre lo que puede ser una "buena razón" dentro de la ciencia y que conforman la identidad práctica y el rostro normativo de la ciencia: publicidad, fiabilidad y autoridad reflexiva. This paper discusses some ways of understanding scientific rationality as practical rationality. Firstly, instrumental models of the rationality of science are rejected. The instrumentalist can hardly establish the independence and goodness of certain ends. In the case of science, determinate ends with respect to which the normative force of our reasons is established do not seem to exist. A false identification of ends with values is what causes many of the confusions. Secondly, a model of practical rationality based in the mastery of tacit knowledge and skills is criticized. Any model of scientific rationality should take into account three constraints about what a "good reason" in scientific matters is, constraints that shape the practical identity and the normative face of science: the constraints of publicity, reliability and reflective authority.
