A traditional diagnosis of the error in the Cartesian skeptical arguments holds that they exploit our tendencies to take a representationalist view of perception. Thinking (perhaps not too clearly) that we perceive only our own sensory states, it seems to us that our perceptual beliefs about physical objects must be justified qua explanations of those sensory states. Such justification requires us to have reasons to reject rival explanations, such as the skeptical hypotheses, which we lack. However, those who (...) adopt the direct realist view of perception still find these arguments plausible, although, according to this diagnosis, they shouldn't. To avoid this objection, I argue that the Cartesian skeptical arguments exploit, not our representationalist tendencies, but our habits for evaluating causal explanatory justifications. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:FEYERABEND'S EPISTEMOLOGY AND BRECHTS THEORY OF THE DRAMA by S. G. Couvalis In his early paper, "On the Improvement of the Sciences and the Arts," Feyerabend argues that, just as rival hypotheses show the shortcomings of entrenched scientific hypotheses, so theatre which presents hypotheses contrary to common beliefs about human beings shows the shortcomings of these beliefs. It develops understanding of human relations more effectively (...) than intellectual debate because it is a more complex medium whose elements can "represent the contrary hypotheses at the same time."1 He takes Brecht to be the first theorist of such a theatre. I shall argue that Brecht's epistemology is similar to Feyerabend's early epistemology and that his dramatic theory is a consequence of it.2 1 shall also argue, however, that Feyerabend is wrong in saying that Brechtian theatre presents contrary hypotheses at the same time, because plays, like descriptions, are theory-laden and Brecht, in any case, intends to show on stage that tragedies have social origins and not to present contrary hypotheses about human beings. According to Brecht, most people improperly assume that human behavior and social relations follow fixed patterns inherent in nature because they have been unable to compare the human behavior they know with that in other societies. They take what they experience to be typically human. Moreover, they interpret their social world as they have been taught: "A child, living in a world of old men... knows the run of things before he can walk."3 Feyerabend brings out the effect of such training very vividly: "The teaching procedures both shape the 'appearance,' or 'phenomenon' and establish a firm connection with words, so that finally the phenomena seem to speak for themselves...."4 Because these interpretations of the social world which children are taught are descriptive, explanatory, and prescriptive, they are more 117 118Philosophy and Literature complex and more dangerous than the interpretations of physical objects they are taught. For example, children learn different evaluations of precisely the same behavior in males and females through being taught how to describe it. In being taught to describe certain behavior as "manly" they are taught both that it arises from a male's nature and that it is laudable behavior for boys but not for girls. "Manly" behavior in a woman is not "confident" or "forthright," but "aggressive" or "pushy." In order to stop us from regarding traditional behavior patterns and social relations as unchangeable, and to enable us to question our descriptions of them, Brecht argues that the dramatist must cause us to cease to regard such patterns and social relations as familiar givens that can only be described in one way. To achieve this, he must not structure his plays on the Aristotelian model. The Aristotelian model makes audiences incapable of criticizing the dramatic message, imparts the view that the sources of tragedy lie in an inexplicable human essence, and presents social rules as if they were unquestionable natural laws. Instead, he should structure his plays to induce in audiences a scientific attitude to social relations and patterns of behavior. Like Feyerabend, Brecht realizes that a scientific attitude is not displayed by collecting descriptions of experience without considering whether the interpretations contained in the descriptions are correct. In Galileo, his view of those who mechanically describe experience in traditional terms is shown in Galileo's replies to the Aristotelian arguments of Andrea. When Andrea argues, "I can see that the sun's not in the same place in the evening and morning. So it can't stand still. It just can't," Galileo replies, "You 'W! What do you see? You see nothing at all. You're just gaping. Gaping isn't seeing." He then demonstrates to Andrea that the apparent motions of objects need not be their real motions because an apparent motion can be caused in more than one way. 5 Brecht shows that the central question for the scientist is not "How shall I collect descriptions of appearances?" but "What is it that I really perceive and how is it caused?" He argues elsewhere that "there's a vast difference between experiment and experience" because experiments are set up to test... (shrink)

What I am calling for is not as radically new as it may sound to ears that are still tuned to positivist frequencies. A very large part of what we value as our cultural monuments can be thought of as metaphoric criticism of metaphor and the characters who make them. The point is perhaps most easily made about the major philosophies. Stephen Pepper has argued, in World Hypotheses,1 that the great philosophies all depend on one of the four "root (...) metaphors," formism, mechanism, organicism, and contextualism, and they are great precisely because they have so far survived the criticism of rival metaphors. Each view of the totality of things claims supremacy, but none has been able to annihilate the others. They all thus survive as still plausible, pending further criticism through further philosophical inquiry. In this view, even the great would-be literalists like Hobbes and Locke are finally metaphorists—simply committed to another kind of metaphor, one that to them seems literal. Without grossly oversimplifying we could say that the whole work of each philosopher amounts to an elaborate critique of the inadequacy of all other philosophers' metaphors. What is more, the very existence of a tradition of a small group of great philosophies is a sign that hundreds of lesser metaphors for the life of mankind have been tested in the great philosophical—that is, critical—wars and found wanting. · 1. World Hypotheses: A Study in Evidence . In Concept and Quality: A World Hypothesis , Pepper suggests that "the purposive act" is a fifth root metaphor. Wayne C.

The probabilistic corroboration of two or more hypotheses or series of observations may be performed additively or multiplicatively . For additive corroboration (e.g. by Laplace's rule of succession), stochastic independence is needed. Inferences, based on overwhelming numbers of observations without unexplained counterinstances permit hyperinduction , whereby extremely high probabilities, bordering on certainty for all practical purposes may be achieved. For multiplicative corroboration, the error probabilities (1 - Pr) of two (or more) hypotheses are multiplied. The probabilities, obtained by (...) reconverting the product, are valid for both of the hypotheses and indicate the gain by corroboration.. This method is mathematically correct, no probabilities > 1 can result (as in some conventional methods) and high probabilities with fewer observations may be obtained, however, semantical independence is a prerequisite. The combined method consists of (1) the additive computation of the error probabilities (1 - Pr) of two or more single hypotheses, whereby arbitrariness is avoided or at least reduced and (2) the multiplicative procedure . The high reliability of Empirical Counterfactual Statements is explained by the possibility of multiplicative corroboration of "all-no" statements due to their strict semantical independence.

In lieu of an abstract, here is a brief excerpt of the content: Against Definition. Eric Matthews. -/- Keywords: definition, mental illness, ideology -/- Varelius rightly says, in the very first sentence of his article, that 'The nature of mental disorder is a controversial issue.' But I do not think he recognizes just how deeply controversial it is. He hopes to be able to find a way of resolving the controversy by his chosen method, based on a consideration of 'the (...) goals that we have in classifying certain persons as mentally disordered.' However, not only does the adoption of that method presuppose that the controversy is resoluble, it is also somewhat circular. For to be able to set out the goals that we have in classifying some people as mentally disordered, we already have to know which persons we so classify, and so what is meant by calling them 'mentally disordered.' There are several appeals to alleged 'intuitions' and one to a 'paradigm case' in Varelius's article; but, if we had such intuitions, they would be all we needed to define the concept of mental disorder, and there would be no need for the further reference to our goals in demarcating this class of human conditions.I want to argue that any alleged 'intuitions' we might have in regard to mental disorder are philosophically useless, and that the controversy about the nature of mental disorder is intrinsically irresoluble. Any claimed intuition can always be met by a rival intuition that is irreconcilable with the first. It is this, indeed, that makes the dispute about mental disorder essentially philosophical, rather than scientific, in character. Philosophical positions have to be based on, and defended by, rational argument, but there necessarily comes a point in any philosophical dispute at which no rational argument can settle the matter one way or the other. Varelius derives his methodology of considering goals of demarcation from some work done using this method on the concept of science. But people have different goals for demarcating 'science' from 'non-science' or 'pseudo-science.' The demarcation is not made, as Varelius suggests, on the basis of such criteria as testability of hypotheses or clarity of concepts; or rather, the application of these criteria themselves is determined by the goals of demarcation. The debate about what is to count as a 'science' is irresoluble in part because what we classify as such has evaluative and practical consequences. To be a 'science,' in our culture, is to be a valued activity, to have a status to be aspired to. This makes arguments about what it is to be scientific what I would like to call 'ideological' in character. Similar considerations apply to the dispute about the nature of mental disorder. Human societies have always distinguished madness from reason, disturbed or disordered behavior, thoughts, and emotions from those that are not disordered. But the purpose of making the distinction, and thus the character of the distinction made, has varied from society to society and from one historical period to another. The historian Roy Porter, in his short work Madness: A Brief History (2002) describes some of the different images of madness which have prevailed at different times in Western culture—as a divine punishment for hubris, as [End Page 53] a source of poetic inspiration, as the inevitable result of moral excess, as diabolical possession, and so on. The modern idea of mental disorder as mental illness is only one possible way of classifying together certain sorts of deviations from normality. Varelius's method of arriving at a definition of mental illness involves 'considering the goals that we have in classifying certain persons as mentally disordered.' But we can ask who are the 'we' in question, and whether 'we' have only one set of goals in classifying people in this way. The history referred to in the preceding paragraph suggests that 'we' means those members of society who do not regard themselves as disordered—the 'normal' people whose behavior can be readily understood by other normal people. Classifying someone as mentally disordered is distinguishing them as 'not one of us,' and this can serve various purposes, for instance, treating them as objects of entertainment in a human zoo, as in Bedlam; or treating them as moral.

It is argued that neither the "theory-informity" of observations nor the Quine-Duhem thesis pose any in principle threat to the objectivity of theory evaluation. The employment of exploratory theories does not generate incommensurability, but on the contrary is responsible for the mensurability and commensurability of explanatory theories, since exploratory theories enable scientists to make observations which are critical in the evaluation of explanatory theories. The employment of exploratory theories and other auxiliary hypotheses does not enable a theory to always (...) accommodate recalcitrant observations to preserve evidential equivalence with a rival theory. Explanatory theories become rapidly degenerating if exploratory theories or other auxiliary hypotheses which inform the original confirmation base are modified to accommodate recalcitrant observations.

Evolutionary biology, indeed any science that attempts to reconstruct prehistory, faces practical limitations on available data. These limitations create the problem of contrast failure: specific observations may fail to discriminate between rival evolutionary hypotheses. Assessing the risk of contrast failure provides a way to evaluate testing protocols in evolutionary science. Here I will argue that part of the methodological critique in the Spandrels paper involves diagnosing contrast failure problems. I then distinguish the problem of contrast failure from the (...) more familiar philosophical problem of underdetermination, and demonstrate how contrast failure arises in scientific practice with an investigation into Lewontin and White’s estimation of an adaptive landscape.

In his Letter on the Blind, Denis Diderot describes, based on mathematical physics, a method for evaluating hypotheses in situations where certainty cannot be reached. This article's thesis is that the author of the Letter extends this method to metaphysical questions of finalism and idealism. Diderot presents each pair of antagonistic positions (finalism-antifinalism and idealism-realism) in such a way that readers are invited to carefully weigh the arguments and to choose the one that appears to be the best, (...) or most probable, position.

Parental burnout is a unique and context-specific syndrome resulting from a chronic imbalance of risks over resources in the parenting domain. The current research aims to evaluate the psychometric properties of the Spanish version of the Parental Burnout Assessment across Spanish-speaking countries with two consecutive studies. In Study 1, we analyzed the data through a bifactor model within an Exploratory Structural Equation Modeling on the pooled sample of participants obtaining good fit indices. We then attained measurement invariance across both gender (...) and countries in a set of nested models with gradually increasing parameter constraints. Latent means comparisons across countries showed that among the participants’ countries, Chile had the highest parental burnout score, likewise, comparisons across gender evidenced that mothers displayed higher scores than fathers, as shown in previous studies. Reliability coefficients were high. In Study 2, we tested the relations between parental burnout and three specific consequences, i.e., escape and suicidal ideations, parental neglect, and parental violence toward one’s children. The medium to large associations found provided support for the PBA’s predictive validity. Overall, we concluded that the Spanish version of the PBA has good psychometric properties. The results support its relevance for the assessment of parental burnout among Spanish-speaking parents, offering new opportunities for cross-cultural research in the parenting domain. (shrink)

Numerous scenarios explain the origin of the eukaryote cell by fusion or endosymbiosis between an archaeon and a bacterium (and sometimes a third partner). We evaluate these hypotheses using the following three criteria. Can the data be explained by the null hypothesis that new features arise sequentially along a stem lineage? Second, hypotheses involving an archaeon and a bacterium should undergo standard phylogenetic tests of gene distribution. Third, accounting for past events by processes observed in modern cells is (...) preferable to postulating unknown processes that have never been observed. For example, there are many eukaryote examples of bacteria as endosymbionts or endoparasites, but none known in archaea. Strictly post‐hoc hypotheses that ignore this third criterion should be avoided. Applying these three criteria significantly narrows the number of plausible hypotheses. Given current knowledge, our conclusion is that the eukaryote lineage must have diverged from an ancestor of archaea well prior to the origin of the mitochondrion. Significantly, the absence of ancestrally amitochondriate eukaryotes (archezoa) among extant eukaryotes is neither evidence for an archaeal host for the ancestor of mitochondria, nor evidence against a eukaryotic host.

Although Mealey's account provides several interesting hypotheses, her integration across disparate samples renders the value of her explanation for psychopathy ambiguous. Recent evidence on Psychopathy Checklist-identified samples (Hare, 1991) suggests primary emotional and cognitive deficits inconsistent with her model. Whereas high-anxious psychopaths display interpersonal deficits consistent with Mealey's hypotheses, low-anxious psychopaths' deficits appear more sensitive to situational parameters than predicted.

The focus of this study is cognitive choice: the selection of one cognitive option (a hypothesis, a theory, or an axiom, for instance) rather than another. The study proposes that cognitive choice should be based on the plausibilities of states posited by rival cognitive options and the utilities of these options' information outcomes. The proposal introduces a form of decision theory that is novel because comparative; it permits many choices among cognitive options to be based on merely comparative plausibilities (...) and utilities. This form of decision theory intersects with recommendations by advocates of decision theory for cognitive choice, on the one hand, and defenders of comparative evaluation of scientific hypotheses and theories, on the other. But it differs from prior decision-theoretic proposals because it requires no more than minimal precision in specifying plausibilities and utilities. And it differs from comparative proposals because none has shown how comparative evaluations can be carried out within a decision-theoretic framework. (shrink)

The main argument of this paper is that an evaluation of the overall explanatory power of a theory is less problematic and more relevant as an assessment of the state of knowledge than evaluation of statistical explanations of single occurrences in terms of likelihoods that are assigned to explananda.

Colic may allow infants to obtain additional investment from their parents. The lack of clear fitness costs of colic and of differences in condition between colicky and non-colicky infants is inconsistent with the hypotheses that colic is an honest signal of need or vigor. These and other characteristics of colic, however, are consistent with the hypothesis that colic is a manipulative signal.

To avoid endless and futile debate, critics of an alternative paradigmatic hypothesis cannot simply state their own paradigmatic assumptions as if they were plain fact while dismissing those of the opposition as self-evidently absurd, because it is exactly those initial assumptions that are brought into question by the paradigmatic proposal. Perceived incredibility is no valid ground for rejection of a paradigm whose alternatives are at least equally incredible, and arguably more so.

‘Rival creator’ arguments suggest that God must have created the best of all possible worlds. These arguments are analyzed and evaluated, and Leibniz’s position defended.

Engineers must deal with risks and uncertainties as a part of their professional work and, in particular, uncertainties are inherent to engineering models. Models play a central role in engineering. Models often represent an abstract and idealized version of the mathematical properties of a target. Using models, engineers can investigate and acquire understanding of how an object or phenomenon will perform under specified conditions. This paper defines the different stages of the modeling process in engineering, classifies the various sources of (...) uncertainty that arise in each stage, and discusses the categories into which these uncertainties fall. The paper then considers the way uncertainty and modeling are approached in science and the criteria for evaluating scientific hypotheses, in order to highlight the very different criteria appropriate for the development of models and the treatment of the inherent uncertainties in engineering. Finally, the paper puts forward nine guidelines for the treatment of uncertainty in engineering modeling. (shrink)

Scientific risk evaluations are constructed by specific evidence, value judgements and biological background assumptions. The latter are the framework-setting suppositions we apply in order to understand some new phenomenon. That background assumptions co-determine choice of methodology, data interpretation, and choice of relevant evidence is an uncontroversial claim in modern basic science. Furthermore, it is commonly accepted that, unless explicated, disagreements in background assumptions can lead to misunderstanding as well as miscommunication. Here, we extend the discussion on background assumptions from basic (...) science to the debate over genetically modified (GM) plants risk assessment. In this realm, while the different political, social and economic values are often mentioned, the identity and role of background assumptions at play are rarely examined. We use an example from the debate over risk assessment of stacked genetically modified plants (GM stacks), obtained by applying conventional breeding techniques to GM plants. There are two main regulatory practices of GM stacks: (i) regulate as conventional hybrids and (ii) regulate as new GM plants. We analyzed eight papers representative of these positions and found that, in all cases, additional premises are needed to reach the stated conclusions. We suggest that these premises play the role of biological background assumptions and argue that the most effective way toward a unified framework for risk analysis and regulation of GM stacks is by explicating and examining the biological background assumptions of each position. Once explicated, it is possible to either evaluate which background assumptions best reflect contemporary biological knowledge, or to apply Douglas' 'inductive risk' argument. (shrink)

In my paper, I propose a certain classification of evaluative expressions. I hypothesize that the basic criterion to distinguish between evaluative and descriptive terms is the faultless disagreement test. Next, I discuss a few kinds of phenomena which seem to render this distinction dubious: context–sensitivity, vagueness and using descriptive terms to express evaluative judgments. Further, I investigate Ch. Kennedy’s proposal according to which gradable adjectives can express two kinds of subjectivity. I modify this account by postulating another sub-class of subjective (...) adjectives which are not subjective due to vagueness and which are not evaluative either as they do not necessarily encode any valence. I propose a linguistic test to identify these expressions. Finally, I check where my classification of adjectives places the predicate of personal taste “tasty”. I suggest that “tasty” is both evaluative and experiential and additionally, it carries a condition of its own use, that is the information that can be used to positively assess the taste of something. This, I argue, makes it similar to thin evaluative terms as it carries no descriptive component at all. (shrink)

This paper reconsiders the possibility of applying the procedure of falsification, which consists in testing a theory by confronting hypotheses derived from the theory with empirical data, in the studies of culture, in particular when evaluating interpretive hypotheses. Falsification, to which, according to Popper and his followers, the natural sciences owe their success, is viewed with strong suspicion when the object of investigation is meanings and values rather than material phenomena. If by interpretation one understands reconstruction of (...) the artefact’s meaning, obvious challenges when falsifying interpretive hypotheses include: the multiplicity, instability and ambiguity (indefiniteness or self-contradictory character) of meanings inherent in artefacts. All of this does not seem to exclude the possibility of identifying as misreadings interpretive hypotheses which clearly contradict relevant (non-contradictory) artefactual evidence. Falsification thus understood seems indispensable in educational contexts. At the same time, it must be admitted that in practice (as contrasted with the logical formula which underlies the procedure) falsification is inconclusive, and the application of the procedure is further complicated when meanings and values are the object of research. This is one of the reasons why falsification in the humanities (as elsewhere) needs to be complemented by other epistemic procedures while the status of literary studies or history of philosophy might best be perceived as partly cognitive (and in so far as the research conducted in these disciplines is empirically testable, also scientific) and partly creative (artistic).

In lieu of an abstract, here is a brief excerpt of the content:The Evaluation of Implicit AnthropologiesJochen Fahrenberg (bio) and Marcus Cheetham (bio)Keywordsmind-body, philosophical assumptions, human natureThe three commentaries and the reviewer’s notes contain valuable reflections and expand on number of important points. There is general agreement that surprisingly little is known about psychologists’, psychotherapists’, clinicians’, and other professionals’ philosophical assumptions about human nature. It is conceivable that these implicit anthropologies represent a potential source of bias in research and practice (...) and that further research is therefore justified.Doctor Walach emphasizes the pluralism of world views, which is evident in the questionnaire response patterns. The findings contradict the assumption that monism, immanence, and a scientific worldview are predominant preconceptions. Instead, psychology students mostly favor ontological or methodological dualism, and con-firm that they have spiritual beliefs or indeed some belief in paranormal phenomena. From this, Dr. Walach extends his thought-provoking perspective to folk psychology, as opposed to mainstream psychology, and reflects on the influence of individual beliefs on scientific culture. It is especially from this perspective that the investigation of certain key concepts and belief systems should be given every encouragement.Doctors Wells and Rackley were particularly interested in the implicit anthropologies of clinicians. They are inclined to attribute individual differences in understanding and interaction with patients to “psychological” traits or to momentary experience rather than to philosophical beliefs. The latter view was supported by the majority of students in our investigation. With respect to psychotherapists and clinicians, our article contained only a short reference to the interviews conducted by Wider. The majority of the forty-two professionals taking part in this pilot study assumed that there may be such differential biases in their fields, but they conceded that the momentary clinical condition and pragmatic necessities would often override such biases. An empirical investigation to differentiate psychological, pragmatic–clinical, and philosophical factors and the associated bias would be an ambitious project; very careful interviews and perhaps participant observation would be necessary. But before undertaking such a study, further descriptive studies and the development of testable hypotheses are required.Doctor Brendel referred to the intricacies of the mind–body problem. We agree that many of the recent philosophical writings show nonreductive physicalism to be among the highly favored conceptions. (We do not know whether this discourse represents the majority opinion of philosophers, psychologists, clinicians, or even neuroscientists.) [End Page 213] The inclusion of this specific conception in the multiple-choice item list would require the inclusion of a specific vocabulary and some definitions that are controversial, even among the proponents of nonreductive physicalism. We decided to restrict the wide spectrum of concepts to five categories. Doctor Brendel goes on to voice explicit support for the conceptualization proposed by Horgan, who recommended a pragmatic approach and the use of double vocabularies. He suggests that context-related features in a given instance would suffice for selecting the most appropriate explanation. It is, however, conceivable that close examination of the decision process would reveal criteria containing or stemming from philosophical assumptions.Doctor Walach makes reference to the complementarity principle, which has a certain intellectual appeal when cross-category relationships are considered, and is not restricted to the domain of physics. Compared with a double-language dualism, the complementarity principle postulates that both frames of reference are fundamentally different in categories, exhaustive within their specific explanation scheme, but are essentially incomplete if, for example, brain and consciousness are viewed as a whole.Pertinent methodological aspects were already addressed in the article and endnote. However, the appropriateness of a questionnaire with which to assess philosophical standpoints will continue to be met with concern and require careful consideration. It is clear that there is no other practical method for gathering in a population like first-year students of psychology representative data about ontological beliefs, religious attitudes, or assumptions on human nature.Doctors Wells and Rackley noted discrepancies in the response to two items relating to spiritual existence after death and the cessation of consciousness with biological death. The two statements seem to be contradictory and the observed inconsistencies point to possible misunderstandings, response tendencies, context-dependent effects, or other shortcomings well-known in research using personality questionnaires. However, the assumed postmortal existence... (shrink)

In this paper I extend the case for a necessitation account of particular laws in Kant's philosophy of science by examining the relation between reason's hypothetical use in the Appendix to the Transcendental Dialectic and the legitimate hypotheses identified in the Doctrine of Method. Building on normative accounts of reason's ideas, I argue that reason's hypothetical use does not describe the connections between objects and their grounds, which lie beyond the reach of the understanding, but merely prescribes the relations (...) between appearances and their conditions, for which the understanding must seek. A legitimate hypothesis, I suggest, is a proposition we hold to be true that fills in one or several of those relations. The problematic character of hypotheses requires that we evaluate our reasons for holding them to be true. While natural modality is grounded in the nature of things, which cannot be fully known, our reasons for assent can and must be grounded on features of objects that are epistemically available to us.

This article examines the evaluative nature of the folk concepts of weakness and strength of will and hypothesizes that their evaluative nature is strongly connected to the folk concepts of blame and credit. We probed how people apply the concepts of weakness and strength of will to prototypical and non-prototypical scenarios. While regarding prototypical scenarios the great majority applied these concepts according to the predictions following from traditional philosophical analyses. When presented with non-prototypical scenarios, people were divided. Some, against traditional (...) analyses, did not apply these concepts, which we explain in terms of a clash of evaluations involving different sorts of blame and credit. Others applied them according to traditional analyses, which we explain in terms of a disposition to be reflective and clearly set apart the different sorts of blame and credit involved. Still others applied them in an inverse way, seemingly bypassing the traditional components resolution and be.. (shrink)

Service geography is one of the branches of applied geography that has emerged as an applied intellectual interest to engage with the immediate direct needs of both urban and rural communities. The importance of studying services is due to their connection to economic planning, so geographical interest in them increases, as applied geography is based on a specific approach and philosophy of relevance or social benefit that focuses on the application of geographical knowledge and skills.

Is there some general reason to expect organisms that have beliefs to have false beliefs? And after you observe that an organism occasionally occupies a given neural state that you think encodes a perceptual belief, how do you evaluate hypotheses about the semantic content that that state has, where some of those hypotheses attribute beliefs that are sometimes false while others attribute beliefs that are always true? To address the first of these questions, we discuss evolution by natural (...) selection and show how organisms that are risk-prone in the beliefs they form can be fitter than organisms that are risk-free. To address the second question, we discuss a problem that is widely recognized in statistics – the problem of over-fitting – and one influential device for addressing that problem, the Akaike Information Criterion (AIC). We then use AIC to solve epistemological versions of the disjunction and distality problems, which are two key problems concerning what it is for a belief state to have one semantic content rather than another.

BackgroundIndividuals with early phase cognitive impairment are frequently affected by existential distress, social avoidance and associated health issues. The demand for efficient psychological support is crucial from both an individual and a societal perspective. We have developed a novel psychological intervention manual for providing a non-medical path to enhanced psychological health in the cognitively impaired population. The current article provides specific information on the randomized controlled trial -design and methods. The main hypothesis is that participants receiving PIPCI will increase their (...) psychological flexibility compared to participants in the active control group and the waiting list control group. The secondary hypotheses are that participants receiving PIPCI will improve psychological health compared to participants in the active control group and the waiting list control group.Materials and MethodsThis three-arm RCT will recruit participants from the cognitive centers at Karolinska University Hospital in Stockholm and randomize approximately 120 individuals in the early phase of cognitive impairment to either an experimental group, an active control group or a waiting list control group. Intervention outcome will be evaluated with self-report questionnaires on physical and psychological aspects of health, cognitive assessment, biological markers and health care costs. Assessments will be performed at pre- and post-intervention, as well as at a 6-month follow-up.DiscussionThe development of a potentially feasible and effective psychological intervention tailored for early phase cognitive impairment has the potential to advance the non-pharmacological intervention field. This is especially important given the extensive burden for many affected individuals and their families and the current lack of effective treatments. If the psychological intervention discussed here shows feasibility and efficacy, there is potential for far-reaching healthcare implications for patients with early cognitive impairment at risk of developing dementia.Clinical Trial RegistrationClinicalTrials.gov: NCT04356924.

I suggest addressing the problems Yarkoni identifies by separating substantive from statistical hypotheses, and treating them differently. A statistical test of experimental data only bears directly on statistical hypotheses. Evaluation of related substantive hypotheses requires an additional, qualitative inference to the best explanation. Statistical inference cannot do all of the work of theory choice.

How can the objectivity of an argument’s conclusion be determined? To propose an answer, this paper builds on Betz’s view of premises as hedged hypotheses. If an argument’s premises are hedged, its conclusion must be hedged as well. But how? The paper first introduces a two-dimensional critical grid. The grid’s vertical dimension is inductive, reflecting the argument’s downward flow from premises to conclusion. It specifies the inductive probability of the conclusion given the premises. The grid’s horizontal dimension is epistemic, (...) focusing on the premises without dropping down to the conclusion. It evaluates the epistemic probability of the premises when conjoined. This two-dimensional grid is then applied to three kinds of cases: vertical and horizontal evaluations rely on point-valued probabilities; vertical and horizontal evaluations rely on interval probabilities; vertical and horizontal evaluations rely on non-numeric plausibilities. The result is that, in each case, the argument’s conclusion can be assigned a credence tag, as it were, that reflects a critical appraisal of its objectivity.

Following an account of the incommensurability argument, an objection, based on assumptions concerning rival theories, is examined and rejected. This rejection leads to an alternative direction of criticism of incommensurability, a direction that involves the articulation of comparative standards of theory evaluation that are independent of meaning invariance.

How should we evaluate an argument in which two witnesses independently testify to some claim? In fact what would happen is that the testimony of the second witness would be taken to corroborate that of the first to some extent, thereby boosting up the plausibility of the first argument from testimony. But does that commit the fallacy of double counting, because the second testimony is already taken as independent evidence supporting the claim? Perhaps the corroboration effect should be considered illogical, (...) since each premise should be seen as representing a separate reason in a convergent argument for accepting the claim as plausible. In this paper, we tackle the problem using argumentation schemes and argument diagramming. We examine a number of examples, and come up with two hypotheses that offer methods of analyzing and evaluating this kind of evidence. (shrink)

Both epistolary rhetoric and the practice of epistolography reflect the fact that competition for prestige was pervasive in Roman culture. Indeed, even Ciceronian letters of consolation, which a modern reader might expect to be exempt from social striving, are shaped by emulation and evaluation. Additionally, consolatory exchanges—letters of consolation preserved together with their replies—show that the challenges to a consolatory letter's bereaved addressee to meet or exceed a certain standard of behavior, and specifically to emulate the letter's author, were answered (...) and challenged in turn.

How are new Bayesian hypotheses generated within the framework of predictive processing? This explanatory framework purports to provide a unified, systematic explanation of cognition by appealing to Bayes rule and hierarchical Bayesian machinery alone. Given that the generation of new hypotheses is fundamental to Bayesian inference, the predictive processing framework faces an important challenge in this regard. By examining several cognitive‐level and neurobiological architecture‐inspired models of hypothesis generation, we argue that there is an essential difference between the two (...) types of models. Cognitive‐level models do not specify how they can be implemented in brains and include structures and assumptions that are external to the predictive processing framework. By contrast, neurobiological architecture‐inspired models, which aim to better resemble brain processes, fail to explain important capacities of cognition, such as categorization and few‐shot learning. The “scaling‐up” challenge for proponents of predictive processing is to explain the relationship between these two types of models using only the theoretical and conceptual machinery of Bayesian inference.

The four-factor structure and psychometric properties of the Polish students adaptation of the Buss and Perry Aggression Questionnaire were investigated. The exploratory factor analyses of the responses of 604 Polish participants generally supported the four-factor model. The factors included Physical Aggression, Verbal Aggression, Anger and Hostility. The correlations between subscales, internal consistency and stability over time were evaluated and proved to be satisfactory. Apart from gender differences, 48 prison inmates and 48 students were interviewed to determine the validity of the (...) Aggression Questionnaire by testing for hypothesized differences between groups. Aggression Questionnaire showed cross-cultural differences in aggression between various nations. (shrink)

To commemorate the 50th anniversary of his passing, this special book features studies on Alexandre Koyré, one of the most influential historians of science of the 20th century, who re-evaluated prevalent thinking on the history and philosophy of science. In particular, it explores Koyré’s intellectual matrix and heritage within interdisciplinary fields of historical, epistemological and philosophical scientific thought. Koyré is rightly noted as both a versatile historian on the birth and development of modern science and for his interest in philosophical (...) questions on the nature of scientific knowledge. In the 1940s and 1950s his activities in the United States established a crucial bridge between the European historical tradition of science studies and the American academic environments, and an entire generation of historians of science grew up under his direct influence. The book brings together contributions from leading experts in the field, and offers much-needed insights into the subject from historical, nature of science, and philosophical perspectives. It provides an absorbing and revealing read for historians, philosophers and scientists alike. (shrink)

Dans les Principes d’économie politique (1848), puis dans son ouvrage posthume et inachevé Sur le socialisme (1879), John Stuart Mill propose une défense ambiguë du « communisme », théorie qui vise selon lui à réformer radicalement le régime de propriété. Cet article entend analyser le statut de l’expérimentation dans l’évaluation millienne de la collectivisation des moyens de production. Il donne ainsi à voir en quoi l’appel à l’expérience – d’abord à petite échelle – de l’hypothèse communiste, que l’on retrouve d’un (...) texte à l’autre, peut se lire comme une invitation positive à réaliser cette doctrine, mais comporte en même temps des limites et des réserves profondes.

This paper focuses on the preliminary evaluation of expressions of moral sentiment under conditions of cultural pluralism. The advance of science and technology puts ever new power over nature in human hands, and if this new power is to more fully serve human ends, then it must become the means or material of human virtue. This prospect poses the question of the relationship between power and virtue, and equally, the question of how scientific advances may be understood to enter into (...) a pluralism of moral doctrines and deliberations. Taking a page from the philosophy of science, the present approach examines the relationship between scientific advances and moral evaluations of developing practices as mediated by contemporary accounts of the virtues of hypotheses. If we conceive of expressions of moral sentiment as hypotheses for the amendment or expansion of existing moral doctrines in the light of new possibilities for action, then this suggests that expressions of moral sentiment may be evaluated, in a preliminary way, by reference to standard lists of the virtues of hypotheses: refutability, conservatism, modesty or simplicity, precision, elegance, and generality. Expressions of moral sentiment are subject to preliminary evaluation, on cognitive grounds, by reference to their prospective integration and/or modification of on-going moral traditions. (shrink)

This paper calls attention to a philosophical presupposition, coined here the continuity thesis which underlies and unites the different, often conflicting, hypotheses in the origin of life field. This presupposition, a necessary condition for any scientific investigation of the origin of life problem, has two components. First, it contends that there is no unbridgeable gap between inorganic matter and life. Second, it regards the emergence of life as a highly probable process. Examining several current origin-of-life theories. I indicate the (...) implicit or explicit role played by the continuity thesis in each of them. In addition, I identify the rivals of the thesis within the scientific community — the almost miracle camp. Though adopting the anti-vitalistic aspect of the continuity thesis, this camp regards the emergence of life as involving highly improbable events. Since it seems that the chemistry of the prebiotic stages and of molecular self-organization processes rules out the possibility that life is the result of a happy accident, I claim that the almost miracle view implies in fact, a creationist position.

Theories of religion that are supported with selected examples can be criticized for selection bias. This paper evaluates major evolutionary hypotheses about religion with a random sample of 35 religions drawn from a 16-volume encyclopedia of world religions. The results are supportive of the group-level adaptation hypothesis developed in Darwin’s Cathedral: Evolution, Religion, and the Nature of Society (Wilson 2002). Most religions in the sample have what Durkheim called secular utility. Their otherworldly elements can be largely understood as proximate (...) mechanisms that motivate adaptive behaviors. Jainism, the religion in the sample that initially appeared most challenging to the group-level adaptation hypothesis, is highly supportive upon close examination. The results of the survey are preliminary and should be built upon by a multidisciplinary community as part of a field of evolutionary religious studies. (shrink)

The received view of an ad hochypothesis is that it accounts for only the observation(s) it was designed to account for, and so non-ad hocness is generally held to be necessary or important for an introduced hypothesis or modification to a theory. Attempts by Popper and several others to convincingly explicate this view, however, prove to be unsuccessful or of doubtful value, and familiar and firmer criteria for evaluating the hypotheses or modified theories so classified are characteristically available. (...) These points are obscured largely because the received view fails to adequately separate psychology from methodology or to recognise ambiguities in the use of ''ad hoc''. (shrink)

It is claimed that Kuipers' approach to explanation opens the possibility for a further refinement of his own refined HD method for the evaluation of theories. One severe problem for the HD method, refined or not, is theory-ladeness. Given that experimental results are theory-laden, the comparative evaluation of alternative hypotheses is always relative to background knowledge. This difficulty can be avoided by supplementing HD considerations with the principle of inference to the best explanation. The authors sketch a program for (...) doing this. The general idea plays on some similarities between Kuipers' account of explanation and Lipton's. The former, however, is considered more flexible than the latter, which makes it even more attractive for the purpose under consideration. (shrink)
