This paper considers the relevance of the Duhem-Quine thesis in economics. In the introductory discussion which follows, the meaning of the thesis and a brief history of its development are detailed. The purpose of the paper is to discuss the effects of the thesis in four specific and diverse theories in economics, and to illustrate the dependence of testing the theories on a set of auxiliary hypotheses. A general taxonomy of auxiliary hypotheses is provided to demonstrate the confounding of auxiliary (...) hypotheses with the testing of economic theory. (shrink)

The comment addresses central issues of a "theory theory" approach as exemplified in Gopnik' and Goldman's BBS-articles. Gopnik, on the one hand, tries to demonstrate that empirical evidence from developmental psychology supports the view of a "theory theory" in which common sense beliefs are constructed to explain ourselves and others. Focusing the informational processing routes possibly involved we would like to argue that his main thesis (e.g. idea of intentionality as a cognitive construct) lacks support at least for two reasons: (...) one methodological and one structural. On the other hand, Goldman raises an important question when he is asking how people ascribe mental states to themselves. Reasons why Goldman's attempt to understand common sense mental representations by using an analogy from visual perception is problematic are discussed. The role which is attributed to a phenomenology is evaluated. (shrink)

This article describes the tension that exists between the views of learning as a means of knowledge transfer and the alternative idea that it is socially situated and not separable from the activities in which it is developed. It concludes that the 'authentic practices' of particular academic domains should be employed in schools to encourage learning rather the culture of schooling itself.

The aim of this paper is to provide a detailed characterisation of some ways in which our preferences reflect our reasons. I will argue that practical reasons can be characterised along two dimensions that influence our preferences: their balance and their weight. This is analogous to a similar characterisation of the way in which probabilities reflect the balance and weight of evidence in epistemology. In this paper, I will illustrate the distinction between the balance and weight of reasons, and show (...) how this is crucial for an adequate account of preference and choice. The upshot is a more complete picture of a particular kind of decision, labelled by Isaac Levi and, more recently, Ruth Chang as ‘hard choices’. These are choices in which one option is better than another in some ways, the other is better than the first in some ways, but neither seems better overall. The distinction between the balance and weight of reasons presents a new way of understanding how hard choices vary by degree and what it is that makes them so hard. (shrink)

Obviously medicine should be evidence-based. The issues lie in the details: what exactly counts as evidence? Do certain kinds of evidence carry more weight than others? (And if so why?) And how exactly should medicine be based on evidence? When it comes to these details, the evidence-based medicine (EBM) movement has got itself into a mess – or so it will be argued. In order to start to resolve this mess, we need to go 'back to basics'; and that means (...) turning to the philosophy of science. The theory of evidence, or rather the logic of the interrelations between theory and evidence, has always been central to the philosophy of science – sometimes under the alias of the 'theory of confirmation'. When taken together with a little philosophical commonsense, this logic can help us move towards a position on evidence in medicine that is more sophisticated and defensible than anything that EBM has been able so far to supply.

Tant qu'un programme de recherche en herbe peut être reconstitué de manière rationnelle en tant que problème progressif, il doit être protégé pendant un certain temps d'un rival puissant existant. Ces considérations, dans leur ensemble, soulignent l’importance de la tolérance méthodologique. Même les fameuses « expériences cruciales » n'auront aucune force pour renverser un programme de recherche. Dans le cadre d'un programme de recherche, des « expériences cruciales mineures » entre versions ultérieures sont assez courantes. DOI: 10.13140/RG.2.2.17935.53922.

Imre Lakatos a proposé une modification du critère de Popper, qu'il a qualifié de « falsification sophistiquée (méthodologique) ». De ce point de vue, le critère de délimitation ne devrait pas s'appliquer à une hypothèse ou à une théorie isolée, mais plutôt à l'ensemble d'un programme de recherche. La falsification méthodologique sophistiquée change le problème du mode d’évaluation théorique en problème de l’évaluation des séries théoriques. DOI: 10.13140/RG.2.2.25555.73761.

Selon Popper, une théorie scientifique peut être légitimement sauvée de la falsification en introduisant une hypothèse auxiliaire permettant de générer de nouvelles prédictions falsifiables. De plus, s’il existe des soupçons de biais ou d’erreur, les chercheurs pourraient introduire une hypothèse auxiliaire falsifiable, qui permettrait de procéder à des tests. De nombreux autres auteurs ont proposé des critères pour démarquer la science de la pseudoscience. Celles-ci incluent généralement la croyance en l'autorité, des expériences irremplaçables, des exemples choisis, le manque de volonté (...) de tester, le non-respect des informations de réfutation, un subterfuge intégré, des explications abandonnées sans remplacement.

Our conscious minds exist in the Universe, therefore they should be identified with physical states that are subject to physical laws. In classical theories of mind, the mental states are identified with brain states that satisfy the deterministic laws of classical mechanics. This approach, however, leads to insurmountable paradoxes such as epiphenomenal minds and illusionary free will. Alternatively, one may identify mental states with quantum states realized within the brain and try to resolve the above paradoxes using the standard Hilbert (...) space formalism of quantum mechanics. In this essay, we first show that identification of mind states with quantum states within the brain is biologically feasible, and then elaborating on the mathematical proofs of two quantum mechanical no-go theorems, we explain why quantum theory might have profound implications for the scientific understanding of one's mental states, self identity, beliefs and free will.

How do we prepare engineering students to make ethical and responsible decisions in their professional work? This paper presents an approach that enhances engineering students’ engagement with ethical reasoning by simulating decision-making in a complex scenario. The approach has two principal inspirations. The first is Anthony Weston’s scenario-based teaching. Weston’s concept of a scenario is a situation that changes in response to choices made by participants, according to an inner logic. Scenarios can dynamically explore open-ended complex problems without imposing predetermined (...) results, allowing students to apply their ethical reasoning in a more realistic fashion. The second inspiration is Thi Nguyen’s theory of games. According to Nguyen, games are the “art of agency,” meaning that they provide a structure under which some result is agreed to be valuable, along with prescribed ways of achieving that result, in a relatively low-stakes and temporary social arrangement. By playing many games, Nguyen argues, we can develop a “library of agency,” that is to say, a set of values and means to achieving them that can inform how we make high-stakes decisions in real life. Engaging with carefully designed game scenarios, then, can enable students to practice making ethical decisions within a structured framework, which unfolds in response to their choices, while their decisions are driven by some defined goal. This roleplaying game–based approach thus allows students to build their own ethical libraries of agency, in preparation for professional decision-making. The approach is illustrated using a specific example recently deployed in a seminar on engineered living materials (building materials that incorporate living tissues). The scenario uses techniques from tabletop roleplaying games (e.g. Dungeons & Dragons) for outcome resolution, adventure design, and character creation. Through the game, students practice making difficult decisions in a humanitarian context. (shrink)

Beginning by offering a conceptual analysis of change – a statement of what change of any kind is – the paper sets out to examine possible ways of understanding a very common and important variety of change that may be called ‘evolutionary’. These changes include anything from the production of a clay pot on a potter's wheel to the emergence of a system of management, or from the effects of an analgesic drug to the development of a new programme of (...) care. As few philosophers have discussed such topics, theories are borrowed from the philosophy of science that attempt to explain the development and rationality of science. The ideas of Karl Popper and Thomas Kuhn are discussed and criticized, before turning to evolutionary theories: Darwinian and Lamarckian. The paper ends by offering a model that, it is hoped, may help in thinking about a wide range of changes. (shrink)

I propose the next steps in the neuropragmatic approach to philosophy that has been advocated by Solymosi and Shook (2013). My focus is the initial process of inquiry implicit in addressing philosophical questions of cognition and mind by utilizing the tools of neuroscientific research. I combine John Dewey’s pattern of inquiry with Charles Peirce’s three forms of inference in order to outline a methodological schema for neuropragmatic inquiry. My goal is to establish ignorance and guessing as well-defined pillars of methodology (...) upon which to build a neuropragmatic approach to inquiry. First, I outline Dewey’s pattern of inquiry, highlighting the initial problematic phase in which recognized ignorance provides the basis upon which to frame a philosophical problem and initiate the trajectory by which philosophical questions may be addressed with the assistance of neuroscientific evidence. Second, I provide an outline of Peirce’s three forms of inference, focusing upon the first phase of abduction: guessing. Third, I explain the transition between ignorance and guessing, urging the benefit of attending to these two aspects of inquiry. Finally, I provide an initial sketch indicating the next steps concerning a pragmatic reconstruction of neurophilosophy, pointing towards the need for a more thorough examination of scientific methodology within and following analyses of philosophical problems and neuroscientific evidence.

It is only when mixing two or more pure substances along a reversible path that the entropy of the mixing can be made physically manifest. It is not, in this case, a mere mathematical artifact. This mixing requires a process of successive stages. In any finite number of stages, the external manifestation of the entropy change, as a definite and measurable quantity of heat, isa fully continuous function of the relevant variables. It is only at an infinite and unattainable limit (...) thata non-uniform convergence occurs. And this occurs when considered in terms of the number of stages together with a distinguishability parameter appropriate to the particular device which is used to achieve reversibility. These considerations, which are of technological interest to chemical engineers, resolve a paradox derived in chemical theory called Gibbs'' Paradox. (shrink)

In this paper I suggest that near-death experiences (NDEs) provide a rational basis for belief in life after death. My argument is a simple one and is modeled on the argument from religious experience for the existence of God. But unlike the proponents of the argument from religious experience, I stop short of claiming that NDEs prove the existence of life after death. Like the argument from religious experience, however, my argument turns on whether or not there is good reason (...) to believe that NDEs are authentic or veridical. I argue that there is good reason to believe that NDEs are veridical and that therefore it is reasonable to believe in the existence of what they seem to be experiences of, namely, a continued state of consciousness after the death of the body. I will then offer some comments on the philosophical import of NDEs, as well as reflections on the current state of contemporary philosophy in light of the neglect of this phenomenon. (shrink)

Many scholars claim that a parsimony principle has ontological implications. The most common such claim is that a parsimony principle entails that the “world” is simple. This ontological claim appears to often be coupled with the assumption that a parsimony principle would be corroborated if the “world” were simple. I clarify these claims, describe some minimal features of simplicity, and then show that both these claims are either false or they depend upon an implausible notion of simplicity. In their stead, (...) I propose a minimal ontological claim: a parsimony principle entails a minimal realism about the existence of objects and laws, in order to allow that the descriptions of the relevant phenomena contain patterns.

The term “evolution” is often used in the administrative sciences to designate dynamic processes of change in general. In biology, evolution has a very specific meaning, namely the application of a generative variation-selective retention scheme to change. Applying this to the administrative sciences is more exacting: describing what the variation consists of, how replication of the generated variation occurs and delineating the population from which the selection is made are far from easy. While it is the intention of this special (...) issue as a whole to provide some empirical examples of evolutionary change in the public and private sectors, this introduction will lay out the main lines of thought in what is often referred to as universal Darwinism and what this means in the administrative sciences. Key concepts here are generative variation, selective retention, and selective institutional environment. According to the authors, the Darwinian scheme of evolutionary theory focuses on how new ideas or concepts arise, how they propagate and influence wider actor thinking and on how the institutional environment in which they operate affects their differential survival. This evolutionary process is an interplay between actors and replicators (sounds, images, and in this context mostly words) in which it cannot be said in advance which one is fooling the other.

Our main aim is to discuss the topic of scientific controversies in the context of a recent issue that has been the centre of attention of many epistemologists though not of argumentation theorists or philosophers of science, namely the ethics of belief in face of rational disagreement. We think that the consideration of scientific examples may be of help in the epistemological debate on rational disagreement, making clear some of the deficiencies of the discussion as it has been produced until (...) now. Another central claim of our paper is that the common view according to which beliefs (and changes of beliefs) may exhibit and commonly exhibit a deontic status can be clarified in the light of Brandom’s approach to normative pragmatics and the pragmatic theories of argumentation that also have a normative character (here our example is van Eemeren’s pragma-dialectics). Our article highlights the similarities between both projects, similarities that to our knowledge were not noticed before. Finally, an important point of the article is that we need to take contextual elements into account in order to develop an adequate theory of disagreement. (shrink)

History and the modern sciences are characterized by what is sometimes called a methodological naturalism that disregards talk of divine agency. Some religious thinkers argue that this reflects a dogmatic materialism: a non-negotiable and a priori commitment to a materialist metaphysics. In response to this charge, I make a sharp distinction between procedural requirements and metaphysical commitments. The procedural requirement of history and the sciences—that proposed explanations appeal to publicly-accessible bodies of evidence—is non-negotiable, but has no metaphysical implications. The metaphysical (...) commitment is naturalistic, but is both a posteriori and provisional, arising from the fact that for more than 400 years no proposed theistic explanation has been shown capable of meeting the procedural requirement. I argue that there is nothing to prevent religious thinkers from seeking to overturn this metaphysically naturalistic stance. But in order to do so they would need to show that their proposed theistic explanations are the best available explanations of a range of phenomena. Until this has been done, the metaphysical naturalism of history and the sciences remains defensible. (shrink)

This paper examines the distinction that is sometimes drawn between analysis and interpretation in the context of qualitative research, and the processes of critical analysis that underpin reflective practice. The authors consider the complementary logical processes involved in analysis and interpretation, and propose a cycle of reductive, inductive and hypothetico-deductive testing that is both rational and creative. The authors argue that the goal of critical reflection and qualitative data analysis is not to produce knowledge that can be justified in terms (...) of ‘correspondence’ to ‘reality’. Instead we propose a pragmatic, coherence view of knowledge that emphasizes the centrality of dialogue with texts, evidence, beliefs and practice. We conclude that evidence and belief are inextricably linked and that combined processes of reductive, inductive and hypothetico-deductive logic need to be used in a transparent manner to establish the credibility of an interpretation. Although there is no clear demarcation between what is found and what is constructed, a commitment to coherence is the basis of a pragmatic theory of knowledge. (shrink)

The question about the potential for consciousness of artificial systems has often been addressed using thought experiments, which are often problematic in the philosophy of mind. A more promising approach is to use real experiments to gather data about the correlates of consciousness in humans, and develop this data into theories that make predictions about human and artificial consciousness. A key issue with an experimental approach is that consciousness can only be measured using behavior, which places fundamental limits on our (...) ability to identify the correlates of consciousness. This paper formalizes these limits as a distinction between type I and type II potential correlates of consciousness (PCCs). Since it is not possible to decide empirically whether type I PCCs are necessary for consciousness, it is indeterminable whether a machine that lacks neurons or hemoglobin, for example, is potentially conscious. A number of responses have been put forward to this problem, including suspension of judgment, liberal and conservative attribution of the potential for consciousness and a psychometric scale that models our judgment about the relationship between type I PCCs and consciousness.

Some philosophers have recently argued that contrary to the traditional view, good scientific theories can in fact be logically inconsistent. The literature is now full of case-studies that are taken to support this claim. I will argue however that as of yet no-one has managed to articulate a philosophically interesting view about the role of logically inconsistent theories in science that genuinely goes against tradition, is plausibly true, and is supported by any of the case studies usually given.

Summary Pluralism and monism are the two current views concerning scientific research and language understanding. Between them there is a third, intermediate, view. We take a procedural methodology of science as exemplified in the work of L. Tondl, and procedural linguistics , as exemplified in the work of B. Harrison, to be representative of this third possibility. Procedures are cognitive, linguistic, and physical processes which, through their hierarchical interconnections can generate fruitful mechanisms . These mechanisms are sensitive to context and (...) operate in heuristic and algorithmic ways. Their similar logical structure points towards a profound unified basis for scientific and linguistic activities, thus providing an interesting bridge between what is achieved by a little child talking to his parents, and a creative scientist struggling to interpret the results of his experiments.

It is a prevalent, if not popular, thesis in the metaphysics of belief that facts about an agent’s beliefs depend entirely upon facts about that agent’s underlying credal state. Call this thesis ‘credal reductivism’ and any view that endorses this thesis a ‘credal reductivist view’. An adequate credal reductivist view will accurately predict both when belief occurs and which beliefs are held appropriately, on the basis of credal facts alone. Several well-known—and some lesser known—objections to credal reductivism turn on the (...) inability of standard credal reductivist views to get the latter, normative, results right. This paper presents and defends a novel credal reductivist view according to which belief is a type of “imprecise credence” that escapes these objections by including an extreme credence of 1.

Kuhn’s “essential tension” between conservative and innovative imperatives in enquiry has an empirical analogue—between the potential benefits of collectivization of enquiry and the social dynamic impediments to effective sharing of information and insights in collective settings. A range of empirical materials from social psychology and organization theory are considered which bear on the issue of balancing these opposing forces and an institution is described in which they are balanced in a way which is appropriate for collective knowledge production.

When reasoning about deontic rules (what one may, should, or should not do in a given set of circumstances), reasoners adopt a violation‐detection strategy, a strategy they do not adopt when reasoning about indicative rules (descriptions of purported state of affairs). I argue that this indicative‐deontic distinction constitutes a primitive in the cognitive architecture. To support this claim, I show that this distinction emerges early in development, is observed regardless of the cultural background of the reasoner, and can be selectively (...) disrupted at the neurological level. I also argue that this distinction emerged as a result of selective pressure favouring the evolution of reasoning strategies that determine survival within dominance hierarchies. (shrink)

Attempts to capture the distinction between categorical and dispositional states in terms of more primitive modal notions – subjunctive conditionals, causal roles, or combinatorial principles – are bound to fail. Such failure is ensured by a deep symmetry in the ways dispositional and categorical states alike carry modal import. But the categorical/dispositional distinction should not be abandoned; it underpins important metaphysical disputes. Rather, it should be taken as a primitive, after which the doomed attempts at reductive explanation can be transformed (...) into circular but interesting accounts. (shrink)

The ontological and analytical status of Marxian social theory has been a matter of fierce controversy since Marx’s death, both within and without Marxist circles. A particular source of contention has been over whether Marxism should be construed as an objective science of the capitalist mode of production or as an ethico-philosophical critique of bourgeois society. This is paralleled by the dispute over whether Marxism ought to be considered a humanism or a structuralism. This article addresses both sides of this (...) debate. The argument is that, rather than Marx’s own social thought being split into incompatible poles, giving rise to ‘two Marxisms’, it forms a coherent unity. Marx’s social theory is neither humanist philosophy, nor structural science, but is in fact realist science, which synthesizes these apparent antinomies, and thereby transcends both. (shrink)

We compare Karl Popper’s ideas concerning the falsifiability of a theory with similar notions from the part of statistical learning theory known as VC-theory . Popper’s notion of the dimension of a theory is contrasted with the apparently very similar VC-dimension. Having located some divergences, we discuss how best to view Popper’s work from the perspective of statistical learning theory, either as a precursor or as aiming to capture a different learning activity.

There is a long history of controversy in ecology over the role of competition in determining patterns of distribution and abundance, and over the significance of the mathematical modeling of competitive interactions. This paper examines the controversy. Three kinds of considerations have been involved at one time or another during the history of this debate. There has been dispute about the kinds of regularities ecologists can expect to find, about the significance of evolutionary considerations for ecological inquiry, and about the (...) empirical credentials of theoretical studies of competition. Each of these elements is examined with an eye toward gaining philosophical clarification of the issues involved. In the process, certain shortcomings of contemporary philosophical theories are revealed. In particular, I argue that plausibility arguments based on background considerations are an important part of the model building tradition, but that current accounts of the structure and evaluation of scientific theories do little to illuminate this side of theoretical ecology.

: Sociologists of Scientific Knowledge sometimes claim to study scientists belonging to other forms of life. This claim causes difficulties, as traditionally Wittgensteinians have taken it to be the case that other forms of life are incomprehensible to us. This paper examines whether, and how, sociologists might gain understanding of another form of life, and whether, and how, this understanding might be passed on to readers. I argue that most techniques proposed for gaining and passing on understanding are inadequate, but (...) I end by describing a method that might work. (shrink)

Cognitive architectures - task-general theories of the structure and function of the complete cognitive system - are sometimes argued to be more akin to frameworks or belief systems than scientific theories. The argument stems from the apparent non-falsifiability of existing cognitive architectures. Newell was aware of this criticism and argued that architectures should be viewed not as theories subject to Popperian falsification, but rather as Lakatosian research programs based on cumulative growth. Newell's argument is undermined because he failed to demonstrate (...) that the development of Soar, his own candidate architecture, adhered to Lakatosian principles. This paper presents detailed case studies of the development of two cognitive architectures, Soar and ACT-R, from a Lakatosian perspective. It is demonstrated that both are broadly Lakatosian, but that in both cases there have been theoretical progressions that, according to Lakatosian criteria, are pseudo-scientific. Thus, Newell's defense of Soar as a scientific rather than pseudo-scientific theory is not supported in practice. The ACT series of architectures has fewer pseudo-scientific progressions than Soar, but it too is vulnerable to accusations of pseudo-science. From this analysis, it is argued that successive versions of theories of the human cognitive architecture must explicitly address five questions to maintain scientific credibility. (shrink)
