In Authority and Estrangement Richard Moran takes some rather illuminating steps towards getting rid of the Cartesian picture of self-knowledge. I argue, however, that Moran’s crucial distinction between deliberative and theoretical attitude is seriously contaminated by that traditional picture. More specifically, I will point out why some crucial aspects of the phenomena that Moran describes in terms of the interplay between the theoretical and the deliberative attitude, should rather be interpreted as a process that takes place within the deliberative attitude (...) itself. The theoretical attitude will, as a result, constitute a rather marginal attitude towards one’s own psychological dispositions and experiences, the adoption of which only makes sense in rather peculiar, often pathological, situations.

Norms—that is, specifications of what we ought to do—play a critical role in the study of informal argumentation, as they do in studies of judgment, decision-making and reasoning more generally. Specifically, they guide a recurring theme: are people rational? Though rules and standards have been central to the study of reasoning, and behavior more generally, there has been little discussion within psychology about why (or indeed if) they should be considered normative despite the considerable philosophical literature that bears on this (...) topic. In the current paper, we ask what makes something a norm, with consideration both of norms in general and a specific example: norms for informal argumentation. We conclude that it is both possible and desirable to invoke norms for rational argument, and that a Bayesian approach provides solid normative principles with which to do so. (shrink)

: In The View From Here, Jay Wallace emphasises that an agent's capacity to regret a past decision is conditioned by the attachments that she may have developed as a result. Those attachments shape the point of view from which she retrospectively deliberates. Wallace stresses, however, that not every normative aspect of her decision is affected by this change in perspective, because her decision will remain as unjustified as it was in the past. I will argue, however, that this approach (...) to justification is inconsistent with the normative import that Wallace ascribes to the actual dynamics of our attachments in his defence of the rationale of regret. If I am right, Wallace's approach is caught in the following dilemma: Either he renounces a nonperspectival approach to justification or he revises his view about the normative import of the actual dynamics of our attachments.

Recent metaphysics has turned its focus to two notions that are—as well as having a common Aristotelian pedigree—widely thought to be intimately related: grounding and essence. Yet how, exactly, the two are related remains opaque. We develop a unified and uniform account of grounding and essence, one which understands them both in terms of a generalized notion of identity examined in recent work by Fabrice Correia, Cian Dorr, Agustín Rayo, and others. We argue that the account comports with antecedently plausible (...) principles governing grounding, essence, and identity taken individually, and illuminates how the three interact. We also argue that the account compares favorably to an alternative unification of grounding and essence recently proposed by Kit Fine. (shrink)

La claridad y la argumentación sirven de refugio frente a la charlatanería en el filosofar, pero quienes enfatizan tales principios metodológicos tienden a identificar la claridad con la literalidad y la argumentación con la formalización. En este trabajo, considero los límites de una elucidación filosófica de nuestras prácticas morales que descanse en tal identificación; para ello, examino la relevancia de la posición original de John Rawls para la determinación de los principios de la justicia y, en general, de los experimentos (...) mentales para el estudio de la moralidad. La relevancia de la posición original depende, a mi entender, de un supuesto de concordancia según el cual, a menos que incurramos en algún error deliberativo, no puede haber discrepancia alguna entre nuestros juicios relativos a la justicia acerca de una situación hipotética y nuestros juicios cuando nos enfrentamos realmente a la misma. A lo largo del texto, trato de mostrar que tal supuesto es insostenible a partir del examen de una experiencia moral particular: a saber, la experiencia del soldado; y, para ello, revindico las virtudes deliberativas de la conciencia expresiva de ciertos hechos frente a una mera conciencia declarativa de los mismos; finalmente, extraigo algunas consecuencias de esta distinción para la definición de un estilo filosófico. Astress on clarity and argumentation may serve as a refuge against quackery, but often those who focus on such methodological principles tend to identify clarity with literalness and argumentation with formalization. My reflection upon the limits of a philosophical style inspired in such an identification is mainly concerned with the use of thought experiments in the elucidation of our moral practices and, more specifically, with the relevance of John Rawls' original position for the determination of the basic principles of justice. To this purpose, I emphasize that the relevance of the original position rests on a matching assumption according to which, if agents deliberate appropriately, there should not be any gap between our judgments concerning justice about a hypothetical situation and our judgments whenever we are actually confronted with it. I will, nevertheless, explore a particular moral experience, namely, that of the soldier, only to conclude that such an assumption is untenable. More specifically, I will defend the deliberative virtues of an expressive awareness of certain facts as opposed to a mere declarative awareness of them. In the last section, I will derive some implications of this distinction as to the articulation of a philosophical style. (shrink)

Stich and Nisbett offer an analysis of the concept of a justified inference rule, building upon the efforts of Goodman. They fault Goodman's view on the grounds that it is incompatible with some recent psychological research on reasoning. We criticize their proposal by arguing that it is subject to much the same objections as those they raise against other accounts.

RESUMO Neste artigo pretendemos mostrar as vantagens do modelo epistemológico coerentista quando aplicado ao universo moral. O ponto de partida será apontar que a justificação da crença moral é dada pela coerência com um sistema coerente de crenças que é consistente e que isso pretende resolver o problema da dicotomia entre fato e valor. Posteriormente, apresentam-se as características centrais do coerentismo holístico e investiga-se o método do equilíbrio reflexivo. O próximo passo será fazer referência a três conhecidas objeções ao coerentismo, (...) a saber: o problema do isolamento, os sistemas coerentes alternativos e a circularidade viciosa. Por fim, procuramos responder a essas objeções apelando para os seguintes argumentos: holismo social, razoabilidade e estabilidade social. ABSTRACT In this paper we aim to demonstrate the advantages of the epistemological coherentist model when applied to the moral sphere. The starting point will be to show that the justification of moral belief is a matter of how beliefs fit together with a coherent system of beliefs that is consistent and that it tries to solve the issue of the fact/value dichotomy. Following this, we shall point out the core characteristics of the holistic coherentism and we will investigate the reflective equilibrium method. Next step is to show three standard objections to coherentism, namely, the isolation problem, the alternative coherent systems objection and the vicious circularity. Finally, we shall then try to respond these criticisms with the following arguments: social holism, reasonableness and social stability. (shrink)

An important obstacle to lawhood in the special sciences is the worry that such laws would require metaphysically extravagant conspiracies among fundamental particles. How, short of conspiracy, is this possible? In this paper we'll review a number of strategies that allow for the projectibility of special science generalizations without positing outlandish conspiracies: non-Humean pluralism, classical MRL theories of laws, and Albert and Loewer's theory. After arguing that none of the above fully succeed, we consider the conspiracy problem through the lens (...) of our preferred view of laws, an elaboration of the MRL view that we call the Better Best System (BBS) theory. BBS offers a picture on which, although all events supervene on a fundamental level, there is no one unique locus of projectibility; rather there are a large number of loci corresponding to the different areas (ecology, economics, solid-state chemistry, etc.) in which there are simple and strong generalizations to be made. While we expect that some amount of conspiracy-fear-inducing special science projectibility is inevitable given BBS, we'll argue that this is unobjectionable. It follows from BBS that the laws of any particular special or fundamental science amount to a proper subset of the laws. From this vantage point, the existence of projectible special science generalizations not guaranteed by the fundamental laws is not an occasion for conspiracy fantasies, but a predictable fact of life in a complex world.

Perhaps the most significant contemporary theory of lawhood is the Best System (/MRL) view on which laws are true generalizations that best systematize knowledge. Our question in this paper will be how best to formulate a theory of this kind. We’ll argue that an acceptable MRL should (i) avoid inter-system comparisons of simplicity, strength, and balance, (ii) make lawhood epistemically accessible, and (iii) allow for laws in the special sciences. Attention to these problems will bring into focus a useful menu (...) of novel MRL theories, some of which solve problems the original MRL theory could not. Hence we conceive of the paper as moving toward a better Best System theory of laws. (shrink)

A logical empiricist “baseline statement” can formalize some propositions established by a body of evidence or set of observations. However, it may not necessarily capture, of two propositions it entails, whether all the subsets of the evidence that establish one proposition also establish the other, vice versa, or neither. Yet, according to this paper, which obtains should sometimes matter for confirmation. It illustrates by showing how this “evidential dependence” can be used to address problems with generalizations of grue-like predicates, and (...) do so still within a very simple broadly Hempelian framework.

In the technical literature of computer science, the concept of an effective procedure is closely associated with the notion of an instruction that precisely specifies an action. Turing machine instructions are held up as providing paragons of instructions that "precisely describe" or "well define" the actions they prescribe. Numerical algorithms and computer programs are judged effective just insofar as they are thought to be translatable into Turing machine programs. Nontechnical procedures (e.g., recipes, methods) are summarily dismissed as ineffective on the (...) grounds that their instructions lack the requisite precision. But despite the pivotal role played by the notion of a precisely specified instruction in classifying procedures as effective and ineffective, little attention has been paid to the manner in which instructions "precisely specify" the actions they prescribe. It is the purpose of this paper to remedy this defect. The results are startling. The reputed exemplary precision of Turing machine instructions turns out to be a myth. Indeed, the most precise specifications of action are provided not by the procedures of theoretical computer science and mathematics (algorithms) but rather by the nontechnical procedures of everyday life. I close with a discussion of some of the rumifications of these conclusions for understanding and designing concrete computers and their programming languages. (shrink)

Some explanations are relatively abstract: they abstract away from the idiosyncratic or messy details of the case in hand. The received wisdom in philosophy is that this is a virtue for any explanation to possess. I argue that the apparent consensus on this point is illusory. When philosophers make this claim, they differ on which of four alternative varieties of abstractness they have in mind. What’s more, for each variety of abstractness there are several alternative reasons to think that the (...) variety of abstractness in question is a virtue. I identify the most promising reasons, and dismiss some others. The paper concludes by relating this discussion to the idea that explanations in biology, psychology and social science cannot be replaced by relatively micro explanations without loss of understanding.

Several major breakthroughs in the history of physics have been prompted not by new empirical data but by thought experiments. James Robert Brown and John Norton have developed accounts of how thought experiments can yield such advances. Brown argues that knowledge gained via thought experiments demands a Platonic explanation; thought experiments for Brown are a window into the Platonic realm of the laws of nature. Norton argues that thought experiments are just cleverly disguised inductive or deductive arguments, so no new (...) account of their epistemology is needed. In this paper, I argue that although we do not need to invoke any Platonic insight to explain thought experimentation, Norton’s eliminativist account fails to capture the unique epistemological importance of thought experiments qua thought experiments. I then present my own account, according to which thought experiments are a particular type of inductive inference that is uniquely suited to generate new breakthroughs. (shrink)

It is argued herein that there are two distinct ways in which all observation vocabularies are prejudiced with respect to theory. An argument based on the demands of adequate translation is invoked to show that even the simplest of our observation predicates must display the first and more obvious grade of bias--intensional bias. It is also argued that any observation vocabulary whose predicates are corrigibly applicable must manifest a second and equally serious grade of bias--extensional bias--independently of whatever intensional bias (...) its predicates may or may not have.

It is held by some philosophers that it is possible that x has a disposition D but, if the stimulus condition obtains, it won’t manifest D because of an intrinsic interference. I will criticize this position on the ground that it has a deeply sceptical consequence, for instance, that, assuming that I am not well informed of the micro-properties of a metal coin, I do not know that it is not water-soluble. But I urge that this is beyond the pale, (...) especially in light of the weight of the practical considerations we take when we use dispositional concepts in everyday life or science. In doing so, further, I will formulate a type of belief-forming inference and claim that it confers justification on commonsensical dispositional beliefs like the one that a metal coin isn’t water-soluble.

One of the most difficult problems in the foundations of physics is what gives rise to the arrow of time. Since the fundamental dynamical laws of physics are (essentially) symmetric in time, the explanation for time's arrow must come from elsewhere. A promising explanation introduces a special cosmological initial condition, now called the Past Hypothesis: the universe started in a low-entropy state. Unfortunately, in a universe where there are many copies of us (in the distant ''past'' or the distant ''future''), (...) the Past Hypothesis is not enough; we also need to postulate self-locating (de se) probabilities. However, I show that we can similarly use self-locating probabilities to strengthen its rival---the Fluctuation Hypothesis, leading to in-principle empirical underdetermination and radical epistemological skepticism. The underdetermination is robust in the sense that it is not resolved by the usual appeal to 'empirical coherence' or 'simplicity.' That is a serious problem for the vision of providing a completely scientific explanation of time's arrow. (shrink)

Rational analysis (Anderson 1990, 1991a) is an empiricalprogram of attempting to explain why the cognitive system isadaptive, with respect to its goals and the structure of itsenvironment. We argue that rational analysis has two importantimplications for philosophical debate concerning rationality. First,rational analysis provides a model for the relationship betweenformal principles of rationality (such as probability or decisiontheory) and everyday rationality, in the sense of successfulthought and action in daily life. Second, applying the program ofrational analysis to research on human reasoning (...) leads to a radicalreinterpretation of empirical results which are typically viewed asdemonstrating human irrationality.

In this paper, I try to articulate and clarify the role of the epistemic authority of experts in Kuhn’s explanation for the transition process between rival paradigms in the scientific revolutionary period. If science progresses, that process should contribute to the attainment of the cognitive aim of science, namely, the articulation of paradigms increasingly successful at the resolution of problems. It is hard to see that process as rational and as attaining the cognitive aim of science without the consideration of (...) epistemic authority.The mistake of Kuhn was to emphasize and clarify insufficiently the role of the epistemic authority of experts; his critics failed for ignoring it altogether.

A contextualist account of modal assertions is sketched that makes their truth sensitive to the presuppositions of the conversation. Support for the account is mustered by considering its application to the context-sensitivity of assertions of subjunctive conditional sentences, explanation sentences, and knowledge sentences.

Riggs v. Palmerhas become famous since Dworkin used it to show that legal positivism is defective. The debate over the merits of Dworkin's claims is still very lively. Yet not enough attention has been paid to the fact that the content of the statute at issue inRiggswas given by thecounterfactual intentionof the legislature. According to arguments from legislative intent, a judicial decision is justified if it is based on the lawmaker's intention. But can legislative intentions be determined counterfactually? More generally, (...) what are the discursive commitments undertaken by a lawyer or a judge, in an exchange of legal reasons, when using this interpretive methodology? This paper addresses these issues considering, in particular, David Lewis's “resemblance” condition and “relevant similarity” between possible worlds in the evaluation of counterfactual statements. The analysis sheds some new light on the debate on theoretical disagreements and shows that Dworkin's conception of law as an argumentative practice is not necessarily at odds with legal positivism. It rather allows us to look at it under a better light. (shrink)

It is more than a half-century since Nelson Goodman [1955] applied what we call the Reflective Equilibrium model of justification to the problem of justifying induction, and more than three decades since Rawls [1971] and Daniels [1979] applied celebrated extensions of this model to the problem of justifying principles of social justice. The resulting Wide Reflective Equilibrium model (WRE) is generally thought to capture an acceptable way to reconcile inconsistency between an intuitively plausible general principle and an intuitively plausible judgment (...) about a particular case. Recently a different model for reconciling moral inconsistency has emerged: Moral Consistency Reasoning [Campbell and Kumar 2012, 2013a; Kumar and Campbell 2012; Campbell 2009: 86?7; Campbell and Woodrow 2003; Wong 2002]. MCR applies when two moral judgments give opposing assessments of (what appear to be) relevantly similar particular cases. Though WRE and MCR are strikingly different, each arguably captures a rationally acceptable method for reconciling moral inconsistency. Moreover, as will be shown, they function in complementary ways. Are they parts of a more comprehensive model of moral reasoning in the face of inconsistency that would explain the attractions of each? This essay first spells out the relevant differences between the models and then formulates a more general model of moral reasoning in the face of inconsistency. ?1 reviews the emergence of Goodman's model that he offers in the spirit of epistemology naturalized, almost a decade before Quine coined the term [1969a]. ?2 analyses six salient features of WRE to be compared with six contrasting features of MCR in ?3. ?4 presents the general model.

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

I argue that Kant’s transcendental idealism and Strawson’s descriptive metaphysics are both examples of what I call methodological conservativism. Methodological conservativism involves the claim that a subset of common first-order beliefs is immune to revision. I argue that there are striking differences between their respective commitments to this position, however. For Kant, his conservativism is based upon a commitment to the reliability of particular results of the sciences of his day. For Strawson, in contrast, his conservativism is based upon his (...) attempted liberation of arguments for the necessity of a certain conceptual scheme from any particular scientific commitments. In fact, for Strawson, no change in scientific commitments could displace the conceptual scheme employed to navigate the manifest world of ordinary perceptual experience. Each approach brings with it challenges with regard to how to accommodate potential scientific theory change. (shrink)

While the philosophical literature has extensively studied how decisions relate to arguments, reasons and justifications, decision theory almost entirely ignores the latter notions. In this article, we elaborate a formal framework to introduce in decision theory the stance that decision-makers take towards arguments and counter-arguments. We start from a decision situation, where an individual requests decision support. We formally define, as a commendable basis for decision-aid, this individual’s deliberated judgment, a notion inspired by Rawls’ contributions to the philosophical literature, and (...) embodying the requirement that the decision-maker should carefully examine arguments and counter-arguments. We explain how models of deliberated judgment can be validated empirically. We then identify conditions upon which the existence of a valid model can be taken for granted, and analyze how these conditions can be relaxed. We then explore the significance of our framework for the practice of decision analysis. Our framework opens avenues for future research involving both philosophy and decision theory, as well as empirical implementations. (shrink)

In this paper, I consider the relationship between Inference to the Best Explanation and Bayesianism, both of which are well-known accounts of the nature of scientific inference. In Sect. 2, I give a brief overview of Bayesianism and IBE. In Sect. 3, I argue that IBE in its most prominently defended forms is difficult to reconcile with Bayesianism because not all of the items that feature on popular lists of “explanatory virtues”—by means of which IBE ranks competing explanations—have confirmational import. (...) Rather, some of the items that feature on these lists are “informational virtues”—properties that do not make a hypothesis \ more probable than some competitor \ given evidence E, but that, roughly-speaking, give that hypothesis greater informative content. In Sect. 4, I consider as a response to my argument a recent version of compatibilism which argues that IBE can provide further normative constraints on the objectively correct probability function. I argue that this response does not succeed, owing to the difficulty of defending with any generality such further normative constraints. Lastly, in Sect. 5, I propose that IBE should be regarded, not as a theory of scientific inference, but rather as a theory of when we ought to “accept” H, where the acceptability of H is fixed by the goals of science and concerns whether H is worthy of commitment as research program. In this way, IBE and Bayesianism, as I will show, can be made compatible, and thus the Bayesian and the proponent of IBE can be friends. (shrink)

Philosophy is a reflective activity. So perhaps it is unsurprising that many philosophers have claimed that reflection plays an important role in shaping and even improving our philosophical thinking. This hypothesis seems plausible given that training in philosophy has correlated with better performance on tests of reflection and reflective reasoning has correlated with demonstrably better judgments in a variety of domains. This article reviews the hypothesized roles of reflection in philosophical thinking as well as the empirical evidence for these roles. (...) This reveals that although there are fairly reliable links between reflection and philosophical judgment among both laypeople and philosophers, the role of reflection in philosophical thinking may nonetheless depend in part on other factors, some of which have yet to be determined. So progress in research on reflection in philosophy may require further innovation in experimental methods and psychometric validation of philosophical measures. (shrink)

Reflectivists consider reflective reasoning crucial for good judgment and action. Anti-reflectivists deny that reflection delivers what reflectivists seek. Alas, the evidence is mixed. So, does reflection confer normative value or not? This paper argues for a middle way: reflection can confer normative value, but its ability to do this is bound by such factors as what we might call epistemic identity: an identity that involves particular beliefs—for example, religious and political identities. We may reflectively defend our identities’ beliefs rather than (...) reflect open-mindedly to adopt whatever beliefs cohere with the best arguments and evidence. This bounded reflectivism is explicated with an algorithmic model of reflection synthesized from philosophy and science that yields testable predictions, psychometric implications, and realistic metaphilosophical suggestions—for example, overcoming motivated reflection may require embracing epistemic identity rather than veiling it (à la Rawls 1971). So bounded reflectivism should be preferred to views offering anything less. (shrink)

: Implicit instruction about values occurs throughout scientific communication, whether in the university classroom or in the larger public forum. The concern of this paper is that the kind of values education that occurs includes "reverse moral education," the idea that moral considerations are at best extra scientific if not simply irrational. The (a)moral education that many scientists unwittingly foist on their "students" undergirds the scientific establishment's typical responses to larger social issues: "Huff!" In this paper I explain the nature (...) of moral education which occurs in the "science classroom" and argue that it is wrongheaded--though there are remedies for its negative effects. (shrink)

The concept of biodiversity has played a central role within conservation biology over the last thirty years. Precisely how it should be understood, however, is a matter of ongoing debate. In this paper we defend what we call a classic multidimensional conception of biodiversity. We begin by introducing two arguments for eliminating the concept of biodiversity from conservation biology, both of which have been put forward in a recent paper by Santana. The first argument is against the concept’s scientific usefulness. (...) The other is against its value as a target of conservation. We show that neither of these objections is successful against the classic multidimensional conception of biodiversity. Biodiversity thus understood is important from a scientific perspective, because it plays important explanatory roles within contemporary ecology. Moreover, although it does not encompass all valuable features of the natural world, this does not show that we should abandon it as a target of conservation. Instead, biodiversity should be conceived as one of many grounds of value associated with ecosystems. This is consistent with concluding that a central aim of conservationists should be to protect biodiversity. (shrink)

Platonists affirm the existence of abstract mathematical objects, and Nominalists deny the existence of abstract mathematical objects. While there are standard arguments in favor of Nominalism, these arguments fail to account for the necessity of Nominalism. Furthermore, these arguments do nothing to explain why Nominalism is true. They only point to certain theoretical vices that might befall the Platonist. The goal of this paper is to formulate and defend a simple, valid argument for the necessity of Nominalism that seeks to (...) precisify the widespread intuition that mathematical objects are somehow ‘spooky’ or ‘mysterious’.

My first goal is to motivate a distinctively metaphysical approach to the problem of induction. I argue that there is a precise sense in which the only way that orthodox Humean and non-Humean views can justify induction is by appealing to extremely strong and unmotivated probabilistic biases. My second goal is to sketch what such a metaphysical approach could possibly look like. After sketching such an approach, I consider a toy case that illustrates the way in which such a metaphysics (...) can help us make progress on the problem of induction. (shrink)

The basic idea of logical expressivism in the Brandomian tradition is that logic makes inferential relations explicit and thereby accessible to critical discussion. But expressivists have not given a convincing explanation of what the point of logical theories is. Peregrin provides a starting point by observing a distinction between making explicit and explication in Carnap’s sense of replacing something unclear and vague by something clear and exact. Whereas logical locutions make inferential relations explicit within a language, logical theories use formal (...) languages to explicate inferential roles and meanings of ordinary-language expressions. But Peregrin also holds that the whole point of logical theories is to provide perspicuous models of inferential structures in ordinary language practice. This turns explication into a mere continuation of making explicit by other means, and it leads to a one-sided conception of logic which has no room for evaluating inferential practice in light of logical theories. As a more convincing alternative, I suggest that expressivists rely on the method of reflective equilibrium. This approach is closely related to Carnapian explication, but it has the potential of correcting informal inferential practice without dubious ambitions to replace ordinary languages by logical formalisms.

This paper argues that machine learning and epidemiology are on collision course over causation. The discipline of epidemiology lays great emphasis on causation, while ML research does not. Some epidemiologists have proposed imposing what amounts to a causal constraint on ML in epidemiology, requiring it either to engage in causal inference or restrict itself to mere projection. We whittle down the issues to the question of whether causal knowledge is necessary for underwriting predictions about the outcomes of public health interventions. (...) While there is great plausibility to the idea that it is, conviction that something is impossible does not by itself motivate a constraint to forbid trying. We disambiguate the possible motivations for such a constraint into definitional, metaphysical, epistemological, and pragmatic considerations and argue that “Proceed with caution” is the outcome of each. We then argue that there are positive reasons to proceed, albeit cautiously. Causal inference enforces existing classification schema prior to the testing of associational claims, but associations and classification schema are more plausibly discovered in a back-and-forth process of gaining reflective equilibrium. ML instantiates this kind of process, we argue, and thus offers the welcome prospect of uncovering meaningful new concepts in epidemiology and public health—provided it is not causally constrained.

Whereas an inference (deductive as well as inductive) is usually viewed as being valid in virtue of its argument form, the present paper argues that scientific reasoning is material inference, i.e., justified in virtue of its content. A material inference is licensed by the empirical content embodied in the concepts contained in the premises and conclusion. Understanding scientific reasoning as material inference has the advantage of combining different aspects of scientific reasoning, such as confirmation, discovery, and explanation. This approach explains (...) why these different aspects (including discovery) can be rational without conforming to formal schemes, and why scientific reasoning is local, i.e., justified only in certain domains and contingent on particular empirical facts. The notion of material inference also fruitfully interacts with accounts of conceptual change and psychological theories of concepts. (shrink)

Confronted with the problem of induction, Hans Reichenbach accepts that we cannot justify that induction is reliable. He tries to solve the problem by proving a weaker proposition: that induction is an optimal method of prediction, because it is guaranteed not to be worse and may be better than any alternative. Regarding the most serious objection to his approach, Reichenbach himself hints at an answer without spelling it out. In this paper, I will argue that there are two workable strategies (...) to rehabilitate Reichenbach’s account. The first leads to the widely discussed method of meta-induction, as proposed by Gerhard Schurz. The second strategy has not been suggested thus far. I will develop the second strategy and argue for it being, in some respects, superior to the first and closer to Reichenbach’s own position. (shrink)

When read as a theory that is supposed to mirror, represent or fit some collection of historical data, critics argue that Kuhn’s theory of paradigm shift in Structure of Scientific Revolutions fails by cherry-picking and underdetermination. When read as the ground for a socio-epistemological conception of rationality, critics argue that Kuhn’s theory fails by either the naturalistic fallacy or underarticulation. This paper suggests that we need not view Structure as a historian’s attempt to accurately depict scientific theory change or a (...) philosopher’s attempt to suggest, more normatively, the factors we ought to consider in theory choice. Instead, we might use Kuhn’s theory as a metaphilosophical frame through which to better understand the limits of otherwise intractable philosophical debates. We can focus on Kuhn’s theory not as a proposition or model to confirm, but as something we might use as a tool for understanding. Philosophers have discussed the justice and care orientations in ethics as two theories for which there will be some common, constraining set of intuitions to confirm one theory over the other, to demonstrate that protecting rights is fundamentally more valuable that fulfilling needs or that fulfilling needs is fundamentally more valuable that protecting rights. Instead of conceptualizing this conversation as a choice between two theories, this paper looks to Ian Hacking’s interpretation of Kuhn’s paradigm concept to suggest that working in the world of justice is very different than working in the world of care, as each orientation is a paradigm with its own cognitive and contextual standards of theory assessment. To start, after Larry Laudan, each has its own ontology, methodology, aims and values. But moreover, after Ian Hacking, each has an even larger, entrenched collection of projectible predicates. Though Carol Gilligan herself uses the metaphor of gestalt shift in a few places to characterize the move from the justice to the care perspective, the insight—that what many assume to be a standard exercise in theory choice is really more of a paradigm shift—has been under theorized by ethicists and ignored by philosophers of science. This paper brings the full resources of Structure and its secondary literature to this metaethical issue, while making the larger point that Structure has an important pragmatic role to play, when it comes to the understanding philosophical debates, even if we cannot secure the truth of Kuhn’s theory.

This essay will discuss some of the ways that narrative works to promote philosophy, called fictive narrative philosophy. The strategy is to discuss the ways that direct and indirect discourse work and to show why indirect discourse fills an important void that direct discourse cannot fulfill.

It is argued that racial profiling is unethical and ought to be avoided and that DNA testing on general populations of innocent people is fraught with dangers.

This essay examines several important issues regarding Galen's depiction of the physiology of the arteries. In the process some of Galen's supporting doctrines on the blood and pulse will also be discussed in the context of a coherent scientific explanation. It will be the contention of this essay that though Galen may often have a polemical goal in mind, he correctly identifies the important and complex role of the arteries in human biological systems.

The number of adjustable parameters in a model or hypothesis is often taken as the formal expression of its simplicity. I take issue with this `definition´ and argue that comparative simplicity has a quasi-empirical measure, reflecting experts’ judgements who track past use of a model-type in or across domains. Since models are represented by restricted sets of functions in a suitable space, formally speaking, a general `measure of simplicity´ may be defined implicitly for the elements of a function space. This (...) paper sketches such a framework starting from intuitive constraints. It is shown how experts’ judgements feed into this framework and how the usual definition can be recovered. A theorem by H. Akaike in the theory of model-choice has recently been used to shine new light on the relationship between the demand for simplicity and empirical success, or even `truth´. The approach favored here permits an alternative answer based on a reliabilist account of justification: if judgements of simplicity track past successful use of a model-type comparative simplicity is evidential and inductive.

There are two facts about word learning that everyone accepts. The first is that words really do have to be learned. There is controversy over how much conceptual structure and linguistic knowledge is innate, but nobody thinks that this is the case for the specific mappings between sounds (or signs) and meanings. This is because these mappings vary arbitrarily from culture to culture. No matter how intelligent a British baby is, for instance, she still has to learn, by attending to (...) the language of the people around her, that rabbits are called ‘rabbits’, that sleeping is called ‘sleeping’, and so on.

In this paper, I analyze the particular conception of reciprocal justification proposed by Nelson Goodman and incorporated by John Rawls into what he called reflective equilibrium. I propose a way of avoiding the twin dangers which threaten to push this idea to either of two extremes: the reliance on epistemically privileged observation reports (or moral judgments in Rawls version), which tends to disrupt the balance struck between the two sides of the equilibrium and to re-establish a foundationalism; and the denial (...) of any privileged status to such reports (or judgments), which makes the equilibrium into a theoretical monolith.

Standard Analytic Epistemology (SAE) names a contingently clustered class of methods and theses that have dominated English-speaking epistemology for about the past half-century. The major contemporary theories of SAE include versions of foundationalism, coherentism, reliabilism, and contextualism. While proponents of SAE don’t agree about how to define naturalized epistemology, most agree that a thoroughgoing naturalism in epistemology can’t work. For the purposes of this paper, we will suppose that a naturalistic theory of epistemology takes as its core, as its starting-point, (...) an empirical theory. The standard argument against naturalistic approaches to epistemology is that empirical theories are essentially descriptive, while epistemology is essentially prescriptive, and a descriptive theory cannot yield normative, evaluative prescriptions. In short, naturalistic theories cannot overcome the is-ought divide. Our main goal in this paper is to show that the standard argument against naturalized epistemology has it almost exactly backwards. (shrink)

In this paper I argue that it is not a priori that all the laws of nature are contingent. I assume that the fundamental laws are contingent and show that some non-trivial, a posteriori, non-basic laws may nonetheless be necessary in the sense of having no counterinstances in any possible world. I consider a law LS (such as 'salt dissolves in water') that concerns a substance S. Kripke's arguments concerning constitution show that the existence of S requires that a certain (...) deeper level law or variants thereof hold. At the same time, that law and its variants may each entail the truth of LS. Thus the existence of S entails LS. Consequently there is no world in which S exists and fails to obey LS. I consider the conditions concerning the fundamental laws that would make this phenomenon ubiquitous. I conclude with some consequences for metaphysics. (shrink)

Despite numerous and increasing attempts to define what life is, there is no consensus on necessary and sufficient conditions for life. Accordingly, some scholars have questioned the value of definitions of life and encouraged scientists and philosophers alike to discard the project. As an alternative to this pessimistic conclusion, we argue that critically rethinking the nature and uses of definitions can provide new insights into the epistemic roles of definitions of life for different research practices. This paper examines the possible (...) contributions of definitions of life in scientific domains where such definitions are used most (e.g., Synthetic Biology, Origins of Life, Alife, and Astrobiology). Rather than as classificatory tools for demarcation of natural kinds, we highlight the pragmatic utility of what we call operational definitions that serve as theoretical and epistemic tools in scientific practice. In particular, we examine contexts where definitions integrate criteria for life into theoretical models that involve or enable observable operations. We show how these definitions of life play important roles in influencing research agendas and evaluating results, and we argue that to discard the project of defining life is neither sufficiently motivated, nor possible without dismissing important theoretical and practical research.
