Human knowledge is a phenomenon whose roots extend from the cultural, through the neural and the biological and finally all the way down into the Precambrian “primordial soup.” The present paper reports an attempt at understanding this Greater System of Knowledge (GSK) as a hierarchical nested set of selection processes acting concurrently on several different scales of time and space. To this end, a general selection theory extending mainly from the work of Hull and Campbell is introduced. The perhaps most (...) drastic change from previous similar theories is that replication is revealed as a composite function consisting of what is referred to as memory and synthesis. This move is argued to drastically improve the fit between theory and human-related knowledge systems. The introduced theory is then used to interpret the subsystems of the GSK and their interrelations. This is done to the end of demonstrating some of the new perspectives offered by this view.

This article concerns the notion of living bodies that Spinoza develops in the Ethics (published posthumously in 1677). While commentators have emphasized the relevance of Spinoza’s works for contemporary physiology, they have neglected to study Spinoza’s own views on this topic. My aim is to draw attention to the specific parti pris that underlies Spinoza’s passages on anatomy. To do so, I first compare Spinoza’s claims on human body with the conceptions developed in his immediate historical environment. Then, I propose (...) to draw a parallel between Lakatos’s notion of “negative heuristics” and the high level of generalization Spinoza demonstrates in his propositions on the human body. This parallel allows me to show how Spinoza’s critical remarks on our knowledge of human body have heuristic value. (shrink)

Modern epistemology is in the peculiar position of retaining its trust in man’s ability to acquire knowledge without being capable of specifying the reasons for our gnosis success. Popper was the first to state that any conclusion concerning the possibility or impossibility of knowing is a transcendental statement and he states, also, that man reaches knowledge while trying to guess. In my opinion, we know things because we assume to have always been aware of them, in the sense that some (...) form of immediate awareness has promptly enabled us to perceive them, identify them, use them. But one needs to ascertain whether the reason is the most suitable faculty to ensure the positive development of knowledge. At last, Kuhn claims the impossibility of comparing different theories. But if we establish a comparison between theories in terms of their complexity, then we must admit that there occurs some progress. (shrink)

The concepts of placebos and placebo effects refer to extremely diverse phenomena. I recommend dissolving the concepts of placebos and placebo effects into loosely related groups of specific mechanisms, including (potentially among others) expectation-fulfillment, classical conditioning, and attentional-somatic feedback loops. If this approach is on the right track, it has three main implications for the ethics of informed consent. First, because of the expectation-fulfillment mechanism, the process of informing cannot be considered independently from the potential effects of treatment. Obtaining informed (...) consent influences the effects of treatment. This provides support for the authorized concealment and authorized deception paradigms, and perhaps even for outright deceptive placebo use. Second, doctors may easily fail to consider the potential benefits of conditioning, leading them to misjudge the trade-off between beneficence and autonomy. Third, how attentional-somatic feedback loops play out depends not only on the content of the informing process but also on its framing. This suggests a role for libertarian paternalism in clinical practice. (shrink)

Virtue ethics has been challenged on empirical grounds by philosophical interpreters of situationist social psychology. Challenges are necessarily challenges to something or other, so it’s only possible to understand the situationist challenge to virtue ethics if we have an antecedent grasp on virtue ethics itself. To this end, I first identify the non-negotiable “hard core” of virtue ethics with the conjunction of nine claims, arguing that virtue ethics does make substantive empirical assumptions about human conduct. Next, I rearticulate the situationist (...) challenge in light of these nine claims. I then turn to a discussion of specifications of several responses typically made by defenders of virtue ethics against the situationist challenge, arguing that most of them either are unsound or give up one of the elements in the hard core. A few, however, survive this criticism, and so I conclude by suggesting ways in which the situationist challenge might be not so much resisted as co-opted. Situational influences can be used to help people simulate virtue, a phenomenon I call factitious virtue. (shrink)

The F-twist is giving way to the methodology of scientific research programs. Milton Friedman's “Methodology for Economics” is being supplanted as the orthodox rationale for neoclassical economics by Imre Lakatos' account of scientific respectability. Friedman's instrumentalist thesis that theories are to be judged by the confirmation of their consequences and not the realism of their assumptions has long been widely endorsed by economists, under Paul Samuelson's catchy rubric “the F-twist.” It retains its popularity among economists who want no truck with (...) methodology, but among the increasing number of able economists who are writing on methodology the F-twist has been surrendered, not so much because these writers have decided it is false, as because something better has finally come along.

In this paper I ask how educational researchers can believe the subjective perceptions of qualitative participant-observers given the concern for objectivity and generalisability of experimental research in the behavioural and social sciences. I critique the most common answer to this question within the educational research community, which posits the existence of two (or more) equally legitimate epistemological paradigms—positivism and constructivism—and offer an alternative that places a priority in educational research on understanding the purposes and meanings humans attribute to educational practices. (...) Only within the context of what I call a transcendent view from somewhere—higher ideals that govern human activities—can we make sense of quantitative as well as qualitative research findings.

When is conceptual change so significant that we should talk about a new theory, not a new version of the same theory? We address this problem here, starting from Gould’s discussion of the individuation of the Darwinian theory. He locates his position between two extremes: ‘minimalist’—a theory should be individuated merely by its insertion in a historical lineage—and ‘maximalist’—exhaustive lists of necessary and sufficient conditions are required for individuation. He imputes the minimalist position to Hull and attempts a reductio : (...) this position leads us to give the same ‘name’ to contradictory theories. Gould’s ‘structuralist’ position requires both ‘conceptual continuity’ and descent for individuation. Hull’s attempt to assimilate into his general selectionist framework Kuhn’s notion of ‘exemplar’ and the ‘semantic’ view of the structure of scientific theories can be used to counter Gould’s reductio , and also to integrate structuralist and population thinking about conceptual change.

This paper highlights some connections between work on truth approximation and work in social epistemology, in particular work on peer disagreement. In some of the literature on truth approximation, questions have been addressed concerning the efficiency of research strategies for approximating the truth. So far, social aspects of research strategies have not received any attention in this context. Recent findings in the field of opinion dynamics suggest that this is a mistake. How scientists exchange and take into account information about (...) each others’ beliefs may greatly influence the accuracy and speed with which the scientific community as a whole approximates the truth. On the other hand, social epistemologists concerned with peer disagreement have so far neglected the question of how practices of responding to disagreements with peers fare with respect to the goal of approximating the truth. Again, work on opinion dynamics shows that this may be a mistake, and that how we ought to respond to disagreements with our peers may depend on the specific purposes of our investigations. (shrink)

Upshot: In our response we focus on five questions that point to important common themes in the commentaries: why start in wicked problems, what kind of system is a scientific perspective, what is the nature of second-order research processes, what does this mean for understanding interdisciplinary work, and how may polyocular research help make real-world decisions.

Conceptualizing behavior decision theoretically as being ‘pulled’ (by an expected future) is fundamentally different from conceptualizing it as ‘pushed’ (or determined by past conditions according to causal laws). However, the fundamental distinction between teleological and non-teleological explanations not withstanding, decision-theoretic and evolutionary ‘ways of world making’ lead to strikingly similar forms of political, philosophical, and economic models. Common Hobbesian roots can account historically for the emergence of such a common ‘PPE’ outlook, while a game-theoretic framework of indirect evolution can accommodate (...) the fundamental methodological tension between teleological and non-teleological approaches or the ‘humanities’ and the ‘science’ traditions in PPE’s disciplines.

A review of data concerning the uneven distribution of phobias suggests that nonassociative, ethological models can account for most of tile important findings that cannot be attributed to expectancy biases. The origin of a variety of fears that appear in fixed developmental patterns across divergent cultures and species can best be explained by biological models.

In his critique of preparedness theory, Davey does not address the limitations of adaptationism. The purpose of this commentary is to outline problems that arise when one assumes that mental illness (e.g., phobic disorder)musthave had adaptive significance for it to have survived the vicissitudes of natural selection.

In Logik der Forschung (1934) and later works, Karl Popper proposed a set of methodological rules for scientists. Among these were requirements that theories should evolve in the direction of increasing content, and that new theories should only be accepted if some of their novel predictions are experimentally confirmed. There are currently two, viable theories of cosmology: the standard cosmological model, and a theory due to Mordehai Milgrom called MOND. Both theories can point to successes and failures, but only MOND (...) has repeatedly made novel predictions that were subsequently found to be correct. Standard-model cosmologists, by contrast, have almost always responded to new observations in a post-hoc manner, adjusting or augmenting their theory as needed to obtain correspondence with the facts. I argue that these methodological differences render a comparison of the two theories in terms of their ‘truthlikeness’ or ‘verisimilitude’ essentially impossible since the two groups of scientists achieve correspondence with the facts in fundamentally different ways, and I suggest that a better guide to the theories’ progress toward the truth might be the methodologies themselves.

What are conspiracy theories? And what, if anything, is epistemically wrong with them? I offer an account on which conspiracy theories are a unique way of holding a belief in a conspiracy. Specifically, I take conspiracy theories to be self-insulating beliefs in conspiracies. On this view, conspiracy theorists have their conspiratorial beliefs in a way that is immune to revision by counter-evidence. I argue that conspiracy theories are always irrational. Although conspiracy theories involve an expectation to encounter some seemingly disconfirming (...) evidence (allegedly planted by the conspirators), resistance to all counter- evidence cannot be justified on these grounds.

This article outlines how conceptual spaces theory applies to modeling changes of scientific frameworks when these are treated as spatial structures rather than as linguistic entities. The theory is briefly introduced and five types of changes are presented. It is then contrasted with Michael Friedman’s neo-Kantian account that seeks to render Kuhn’s “paradigm shift” as a communicatively rational historical event of conceptual development in the sciences. Like Friedman, we refer to the transition from Newtonian to relativistic mechanics as an example (...) of “deep conceptual change.” But we take the communicative rationality of radical conceptual change to be available prior to the philosophical meta-paradigms that Friedman deems indispensable for this purpose.

Maxwellian electrodynamics genesis is considered in the light of the author’s theory change model previously tried on the Copernican and the Einstein revolutions. It is shown that in the case considered a genuine new theory is constructed as a result of the old pre-maxwellian programmes reconciliation: the electrodynamics of Ampere-Weber, the wave theory of Fresnel and Young and Faraday’s programme. The “neutral language” constructed for the comparison of the consequences of the theories from these programmes consisted in the language of (...) hydrodynamics with its rich content of analogous models ranging from the uncompressible fluid up to molecular vortices. The programmes’ meeting led to construction of the whole hierarchy of crossbred objects beginning from the displacement current and up to common hybrids. After that the interpenetration of the pre-maxwellian programmes began that marked the beginning of theoretical schemes of optics and electromagnetism unification. Maxwell’s programme did assimilate some ideas of the Ampere-Weber programme, as well as the presuppositions of the programmes of Fresnel and Faraday; and the significance of this fact for further methodology of scientific research programmes development is discussed. It is argued that the core of Maxwell’s unification strategy was formed by Kantian epistemology looked through the prism of William Whewell and such representatives of Scottish Enlightenment as Thomas Reid and William Hamilton. All these enabled Maxwell to start to unify not only optics and electromagnetism, but British and continental research traditions as well. Maxwell’s programme did supersede the Ampere-Weber one because Maxwell did put forward as a synthetic principle the idea, that differed from that of Ampere-Weber by its flexible and contra-ontological, strictly epistemological, Kantian character. For Maxwell, ether was not the last building block of physical reality, from which fields and charges should be constructed . “Action at a distance”, “incompressible fluid”, “molecular vortices” were only analogies for Maxwell, capable to direct the researcher on the “right” mathematical relations. From the “representational” point of view all this hydrodynamical models were doomed to failure efforts to describe what can not be described in principle – things in themselves, the “nature” of electrical and magnetic phenomena. On the contrary, Maxwell aimed his programme to find empirically meaningful mathematical relations between the electrodynamics basic objects, i.e. the creation of inter - coordinated electromagnetic field equations system. Namely the application of this epistemology enabled Hermann von Helmholtz and his pupil Heinrich Hertz to arrive at such a version of Maxwell’s theory that served a heuristical basis for the radiowaves discovery.

By understanding laws of nature as geometrical rather than linguistic entities, this paper addresses how to describe theory structures and how to evaluate their continuity. Relying on conceptual spaces as a modelling tool, we focus on the conceptual framework an empirical theory presupposes, thus obtain a geometrical representation of a theory’s structure. We stress the relevance of measurement procedures in separating conceptual from empirical structures. This lets our understanding of scientific laws come closer to scientific practice, and avoids a widely (...) recognised deficit in current philosophy of science accounts, namely to risk a collapse of the physical into the mathematical.

Philosophical analyses of scientific methodology have long understood intuition to be incompatible with a rule based reasoning that is often considered necessary for a rational scientific method. This paper seeks to challenge this contention by highlighting the indispensable role that intuition plays in the application of methodologies for scientific discovery. In particular, it seeks to outline a positive role for intuition and personal judgment in scientific discovery by exploring a comparison between the use of heuristic reasoning in scientific practice and (...) engineering design. While these discussions share many features, it will also be shown that the successful use of heuristics in engineering design is often considered to depend on a crucial factor that is markedly absent from accounts of the use of heuristics in scientific discovery; experienced judgment. In the final sections of this paper, I will compare attitudes to the role of computer analysis in scientific and engineering practices, with the aim of showing how the limitations of scientific discovery machines reveal the need for including intuition in philosophical accounts of heuristic reasoning in scientific discovery.

Theoretical economics should not be divorced from real life. If theoretical research cannot provide a good explanation for real-world economic phenomena, then we have to question the appropriateness of the paradigm that our theoretical research follows. The battle between neoclassical macroeconomics and Keynesian economics has exposed the inadequacy of the paradigm that modern mainstream economics has followed. Neoclassical macroeconomics and Keynesian economics have the same microeconomic basis. However, the paradigm of the microeconomics on which they are based has serious flaws—the (...) scarcity hypothesis and the economic man hypothesis—do not conform to the facts. These two hypotheses are the basis for other hypotheses and principles, but neither of these two hypotheses holds up to scrutiny. Then the economics edifice built on this foundation is certainly unstable, and the corresponding economic policies are certainly not perfect. (shrink)

Kuhn's theory of paradigm reveals a pattern of scientific progress, in which normal science alternates with scientific revolution. But Kuhn underrated too much the function of scientific test in his pattern, because he focuses all his attention on the hypothetico-deductive schema instead of Bayesian schema. This paper employs Bayesian schema to re-examine Kuhn's theory of paradigm, to uncover its logical and rational components, and to illustrate the tensional structure of logic and belief, rationality and irrationality, in the process of scientific (...) revolution.

Although prima facie no more than a successful private detective, Sherlock Holmes is a classic exponent of scientific method and has laid down several fundamental rules of scientific discovery and truth?detection. While he rediscovered and modified well?known principles of induction, analysis and synthesis, and decision theory, he also made significant contributions to patterns of explanation, and with his ?principle of exclusion? was an ingenious innovator. This latter cornerstone of Holmes's methodology led him to an interesting modal theory of the ?improbable (...) possible? as a competitor to the famous doctrine of the ?impossible probable? put forward by Aristotle in de Arte Poetica. Holmes's scientific discipline was seasoned by warmth, understanding, and boldness. (shrink)

What is attention? Attention is often seen as a subject matter for the hard sciences of cognitive and brain processes, and is understood in terms of sub-personal mechanisms and processes. Correspondingly, there still is a stark contrast between the central role attention plays for the empirical investigation of the mind in psychology and the neurosciences, and its relative neglect in philosophy. Yet, over the past years, several philosophers have challenged the standard conception. A number of interesting philosophical questions concerning the (...) nature of attention arise. This article provides an introduction to contemporary debates concerning these questions. In particular, it discusses the question of how the pre-theoretic conception of attention might be reconciled with a scientific conception, arguments that provide support for an anti-reductivist theory of attention, and sketches several recent anti-reductivist theories and their inter-relations.

The Adam Smith problem refers to a claimed inconsistency between the Theory of Moral Sentiments and the Wealth of Nations, regarding the portrayal of human nature in these two books. Previous research predominantly resolved the claimed inconsistency by uncovering virtuous, less selfish character traits in the Wealth of Nations. This article voices caution. I acknowledge – on methodological grounds – fundamental differences regarding the portrayal of human nature in Smith’s behavioral ethics, i.e. the Theory of Moral Sentiments, as compared with (...) Smith’s economic research. The key argument is that Smith’s two books address different research problems and hence do not, need not and cannot adopt the same view of human nature – for methodological reasons, so my argument. Adam Smith scholarship overlooked that Smith himself in considerable degrees understood “economic man” as a heuristic abstraction. I connect to the philosophies of science of Imre Lakatos and Karl Popper. (shrink)

My main aim in this paper is to clarify the concepts of referential success and of referential continuity that are so crucial to the scientific realism debate. I start by considering the three dominant theories of reference and the intuitions that motivate each of them. Since several intuitions cited in support of one theory conflict with intuitions cited in support of another something has to give way. The traditional policy has been to reject all intuitions that clash with a chosen (...) theory. A more radical policy, tied to some experimental philosophers, has called for the rejection of any evidential role for intuitions. I explore a largely ignored third alternative, i.e. saving intuitions (and their evidential role) even when they are at odds. To accommodate conflicting intuitions different sets of internally consistent (yet externally inconsistent) intuitions are taken to lend credence to different concepts of reference. In the current context, this means that the concepts of referential success and referential continuity are not monolithic. They are what I call 'polylithic'. This paper is as much about meta-philosophical concerns with the role of intuitions as it is about reference and the scientific realism debate. Regarding the former I hope that a blueprint will emerge for similar projects in other philosophical domains. Regarding the latter, I hope that polylithicity helps disentangle claims about referential success and continuity in the scientific realism debate by making perspicuous which concepts are best equipped to evaluate the realist's epistemic claims against the historical record of science.

In this paper, I offer an explication of the notion of local explanation. In the literature, local explanations are considered as metaphysically and methodologically satisfactory: local explanations reveal the contingency of science and provide a methodologically sound historiography of science. However, the lack of explication of the notion of local explanation makes these claims difficult to assess. The explication provided in this paper connects the degree of locality of an explanans to the degree of contingency of the explanandum. Moreover, the (...) explication is shown to be compatible with the methodological need for a general consideration in the historiography of science. In this way, the explication satisfies the need to explicate an important notion, connects local explanations and contingency, and enables us to see how local explanations and general considerations can be connected. However, the explication also sheds critical light on many claims and expectations that are associated with local explanations and their satisfactoriness. (shrink)

This paper introduces and defends an account of model-based science that I dub model pluralism. I argue that despite a growing awareness in the philosophy of science literature of the multiplicity, diversity, and richness of models and modeling practices, more radical conclusions follow from this recognition than have previously been inferred. Going against the tendency within the literature to generalize from single models, I explicate and defend the following two core theses: any successful analysis of models must target sets of (...) models, their multiplicity of functions within science, and their scientific context and history and for almost any aspect x of phenomenon y, scientists require multiple models to achieve scientific goal z.

Es wird die Frage untersucht, ob die Annahme der Existenz von universellen Normen für die Annäherung der Wissenschaft an die Wahrheit nicht in praxi lediglich Gegenwartszentrismus und Ethnozentrismus heißt. Die griechisch-römische Zivilisation förderte die Wissenschaft durch ihre Demokratie, aber andere Zivilisationen haben sehr wertvolle Datensammlungen geliefert. Die Universalität der Wissenschaft impliziert u. a. daß, wo verschiedene Zivilisationen mit ihren Wissenschaften einander begegnen, sie von einander lernen können.
