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 chapter begins to construct our space–time model of the socio‐cognitive network of individual actors. To do this, it formulates a number of assumptions about the structure and evolution of this network. The chapter first proposes six hypotheses concerning the structure of the network. These hypotheses will clarify our formalization of the cognitive universes of individual actors. The chapter then introduces eight additional hypotheses concerning the evolution of the network. The evolution of the network results, on the one hand, from (...) communications between individual actors and, on the other hand, from these cognitive processes internal to the actors that constitute their categorization operations. This distinction between inter‐individual communication and intra‐individual categorization is analytical, because in reality any communication concretely established between real actors has an intentionality dimension that itself implies a part of cognition.

This paper introduces pragmatic hypotheses and relates this concept to the spiral of scientific evolution. Previous works determined a characterization of logically consistent statistical hypothesis tests and showed that the modal operators obtained from this test can be represented in the hexagon of oppositions. However, despite the importance of precise hypothesis in science, they cannot be accepted by logically consistent tests. Here, we show that this dilemma can be overcome by the use of pragmatic versions of precise hypotheses. These pragmatic (...) versions allow a level of imprecision in the hypothesis that is small relative to other experimental conditions. The introduction of pragmatic hypotheses allows the evolution of scientific theories based on statistical hypothesis testing to be interpreted using the narratological structure of hexagonal spirals, as defined by Pierre Gallais.

The notion of subjective indistinguishability has long played a central role in explanations of the force of Cartesian sceptical hypotheses. I argue that sceptical hypotheses do not need to be subjectively indistinguishable to be compelling and I provide an alternative diagnosis of their force that explains why this is the case. My diagnosis focuses on the relation between one’s experiences and third-personal accounts of the circumstances in which these experiences occur. This relation is characterized by a distinctive gap that leaves (...) room for questions about the nature of one’s circumstances, providing sceptical hypotheses with a foothold. I argue that this gap lends sceptical hypotheses their force and renders the stipulation of subjective indistinguishability unnecessary. (shrink)

Unethical behavior is important to study because it may have an adverse influence on organizational performance. This paper is an attempt to better understand why individuals behave as they do when faced with ethical dilemmas. We first explore the definition, theories and models of ethical behaviors and accountability. This discussion of societal ethics and accountability as forms of social control segues into a discussion of how accountability may influence ethical behaviors. Based on the business ethics and accountability literatures, we suggest (...) a number of research questions and hypotheses that need to be tested, as well as an appropriate research strategy.

Singularity Hypotheses: A Scientific and Philosophical Assessment offers authoritative, jargon-free essays and critical commentaries on accelerating technological progress and the notion of technological singularity. It focuses on conjectures about the intelligence explosion, transhumanism, and whole brain emulation. Recent years have seen a plethora of forecasts about the profound, disruptive impact that is likely to result from further progress in these areas. Many commentators however doubt the scientific rigor of these forecasts, rejecting them as speculative and unfounded. We therefore invited prominent (...) computer scientists, physicists, philosophers, biologists, economists and other thinkers to assess the singularity hypotheses. Their contributions go beyond speculation, providing deep insights into the main issues and a balanced picture of the debate. (shrink)

Scientific hypotheses may either predict particular unknown facts or accommodate previously-known data. Although affirmed predictions are intuitively more rewarding than accommodations of established facts, opinions divide whether predictive hypotheses are also epistemically superior to accommodation hypotheses. This paper examines the contribution of predictive hypotheses to discoveries of several bio-molecular systems. Having all the necessary elements of the system known beforehand, an abstract predictive hypothesis of semiconservative mode of DNA replication was successfully affirmed. However, in defining the genetic code whose biochemical (...) basis was unclear, hypotheses were only partially effective and supplementary experimentation was required for its conclusive definition. Markedly, hypotheses were entirely inept in predicting workings of complex systems that included unknown elements. Thus, hypotheses did not predict the existence and function of mRNA, the multiple unidentified components of the protein biosynthesis machinery, or the manifold unknown constituents of the ubiquitin–proteasome system of protein breakdown. Consequently, because of their inability to envision unknown entities, predictive hypotheses did not contribute to the elucidation of cation theories remained the sole instrument to explain complex bio-molecular systems, the philosophical question of alleged advantage of predictive over accommodative hypotheses became inconsequential.

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.

On the status of hypotheses in science, and why scientists would be better off asking questions.

Proponents of evolutionary debunking arguments aim to show that certain genealogical explanations of our moral faculties, if true, undermine our claim to moral knowledge. Criticisms of these arguments generally take the debunker’s genealogical explanation for granted. The task of the anti-debunker is thought to be that of reconciling the truth of this hypothesis with moral knowledge. In this paper, I shift the critical focus instead to the debunker’s empirical hypothesis and argue that the skeptical strength of an evolutionary debunking argument (...) is dependent upon the evidence for that hypothesis—evidence which, upon further inspection, proves far from compelling. Following that, however, I suggest that the same considerations which spell trouble for the empirical hypotheses of traditional debunking arguments can also be taken to give rise to an alternative—and better supported—style of debunking argument.

The intention of the present essay is to urge a reconsideration of the Realism-Phenomenalism-Issue, mainly and primarily in regard to the interpretation of scientific hypotheses; secondarily also relating to the basic problems of epistemology.

This article thinks about changes in the conception of hypothesis during the early modern period. It explains that during this period there was an urgency to redefine human knowledge so that uncertainty became one of its inevitable and acceptable features, and certainty was replaced by probability as an adequate achievement in knowledge of the natural world. It discusses Isaac Newton's deep-seated rejection of hypotheses and the assumption that their use in natural philosophy would compromise its status as genuine scientific knowledge.

Théorie économique élaborée dans les années 1960, l'hypothèse d'instabilité financière postule que le système capitaliste est instable par essence : toute phase d'équilibre apparent ne fait qu'encourager les acteurs du marché à prendre davantage de risques, qui provoquent de nouvelles crises. Décriée à l'époque, cette analyse est aujourd'hui considérée comme l'une des plus à même d'expliquer la crise actuelle. Elle offre une première approche passionnante d’une oeuvre dense, jusqu’à présent méconnue en France.

It is commonly hypothesized that scientists are more likely to engage in data falsification and fabrication when they are subject to pressures to publish, when they are not restrained by forms of social control, when they work in countries lacking policies to tackle scientific misconduct, and when they are male. Evidence to test these hypotheses, however, is inconclusive due to the difficulties of obtaining unbiased data. Here we report a pre-registered test of these four hypotheses, conducted on papers that were (...) identified in a previous study as containing problematic image duplications through a systematic screening of the journal PLoS ONE. Image duplications were classified into three categories based on their complexity, with category 1 being most likely to reflect unintentional error and category 3 being most likely to reflect intentional fabrication. We tested multiple parameters connected to the hypotheses above with a matched-control paradigm, by collecting two controls for each paper containing duplications. Category 1 duplications were mostly not associated with any of the parameters tested, as was predicted based on the assumption that these duplications were mostly not due to misconduct. Categories 2 and 3, however, exhibited numerous statistically significant associations. Results of univariable and multivariable analyses support the hypotheses that academic culture, peer control, cash-based publication incentives and national misconduct policies might affect scientific integrity. No clear support was found for the “pressures to publish” hypothesis. Female authors were found to be equally likely to publish duplicated images compared to males. Country-level parameters generally exhibited stronger effects than individual-level parameters, because developing countries were significantly more likely to produce problematic image duplications. This suggests that promoting good research practices in all countries should be a priority for the international research integrity agenda. (shrink)

Moral skeptics maintain that we do not have moral knowledge. Traditionally they haven’t argued via skeptical hypotheses like those provided by perceptual skeptics about the external world, such as Descartes’ deceiving demon. But some believe this can be done by appealing to hypotheses like moral nihilism. Moreover, some claim that skeptical hypotheses have special force in the moral case. But I argue that skeptics have failed to specify an adequate skeptical scenario, which reveals a general lesson: such arguments are not (...) a promising avenue for moral skeptics to take. They’re ultimately weaker when applied to morality compared to perception. (shrink)

The unifying theme of this issue is Plato’s dialectical view of mathematical progress and hypotheses. Besides provisional propositions, he calls concepts and goals also hypotheses. He knew mathematicians create new concepts and goals as well as theorems, and abandon many along the way, and erase the creative process from their proofs. So the hypotheses of mathematics necessarily change through use — unless Benson is correct that Plato believed mathematics could reach the unhypothetical goals of dialectic. Landry discusses Plato on mathematical (...) and philosophical problem solving. Arsen and White relate Plato’s philosophy to mathematics in his time, and to Aristotle. (shrink)

Cet article prend acte de l’existence d’une pensée écologique chez Marx, consignée principalement dans les cahiers de notes consacrés à l’agriculture. Il propose de s’interroger sur les raisons pour lesquelles Marx en est venu, à partir de 1865, à prêter attention à la destruction des ressources naturelles entraînée par leur gestion capitaliste, alors qu’il ne s’était pas, jusqu’alors, montré sensible à cette question. L’hypothèse proposée, à partir d’une lecture attentive des extraits de Liebig recopiés dans le cahier de 1865-1866 consacré (...) à l’agriculture et récemment publié dans le tome IV/18 de la MEGA 2, est la suivante : la manière dont Liebig décrit l’exploitation des ressources naturelles par l’agriculture capitaliste offre un parallèle frappant avec la manière dont Marx analyse l’exploitation de la force de travail dans le procès de production capitaliste au fil des différentes rédactions de ce qui deviendra le livre I du Capital. L’article présente plusieurs preuves textuelles de ce parallèle, et soutient qu’il offre une explication plausible du soudain intérêt de Marx pour la question écologique. (shrink)

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.

Leibniz differs from Descartes insofar as he submits the search for mechanical explanations to regulatory norms. This is the case, for instance, in dioptrics: provided the law of sines is shown to conform to a sufficient reason of functionality, a relevant mechanical hypothesis is found acceptable. Explaining by means of hypotheses implies a twofold process of connections between an analytic model defining such an order of the elements as may fit the norm of a mathesis, and a presupposed mechanical disposition (...) of the elements such as may produce the constant effects revealed through experience.

Evidence-based medicine frequently uses statistical hypothesis testing. In this paradigm, data can only disconfirm a research hypothesis’ competitors: One tests the negation of a statistical hypothesis that is supposed to correspond to the research hypothesis. In practice, these hypotheses are often misaligned. For instance, directional research hypotheses are often paired with non-directional statistical hypotheses. Prima facie, one cannot gain proper evidence for one’s research hypothesis employing a misaligned statistical hypothesis. This paper sheds lights on the nature of and the reasons (...) for such misalignments and it provides a thorough analysis of whether they pose a threat to evidence-based medicine. The upshots are that the misalignments are often hidden for clinicians and that although some cases of misalignments can be partially counterbalanced, the overall threat is non-negligible. The counterbalances either lead to methodological inadequacy, loss of statistical power, or involve a lack of information that could be crucial for decision making. This result casts doubt on various findings of medical studies in addition to issues associated with under-powered studies or the replication crisis. (shrink)

I investigate the epistemic status of the hypotheses and other premises used in Socrates’ ‘arguments from a hypothesis’ in the Meno, and of the conclusions drawn from them, and argue that, while they are taken by Socrates to fall short of knowledge, he takes them all to have a positive epistemic status, and is not committed to advancing them only tentatively.

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)

Although it is often said that economics is too much like physics, to a physicist economics is not at all like physics. The difference is in the scientific methods of the two fields: theoretical economics uses a top down approach in which hypothesis and mathematical rigor come first and empirical confirmation comes second. Physics, in contrast, embraces the bottom up ‘experimental philosophy’ of Newton, in which ‘hypotheses are inferred from phenomena, and afterward rendered general by induction’. Progress would accelerates if (...) economics were to truly make empirical verification the ultimate arbiter of theories, which would force it to open up to alternative approaches. (shrink)

The history of biochemistry and molecular biology is replete with examples of erroneous theories that persisted for considerable lengths of time before they were rejected. This paper examines patterns of dissolution of three such erroneous hypotheses: The idea that nucleic acids are tetrads of the four nucleobases (‘the tetranucleotide hypothesis’); the notion that proteins are collinear with their encoding genes in all branches of life; and the hypothesis that proteins are synthesized by reverse action of proteolytic enzymes. Analysis of these (...) cases indicates that amassed contradictory empirical findings did not prompt critical experimental testing of the prevailing theories nor did they elicit alternative hypotheses. Rather, the incorrect models collapsed when experiments that were not purposely designed to test their validity exposed new facts. (shrink)

Are men oppressed as men? The evidence given in support of affirmative responses to this question usually consists in examples of harms, limitations, or requirements masculinity imposes on men: men are expected to pay on dates, men must be breadwinners for their families, men can be drafted for war, and so forth.

Leibniz’s conception of the relativity of motion has been discussed at length for a very long time. This paper doesn’t aim to give a full solution to this question, but to contribute to the debate by clarifying how the principle of relativity is introduced, justified and used in the “Dynamica”. Four different principles are identified : one purely geometrical, and three (meta) physical principles, which express God’s wisdom : a principle of equivalence of hypotheses linked to the action/reaction principle, a (...) Galilean principle of relativity and a general principle which apply not only to rectilinear motions but also to circular ones. I argue that to appreciate the coherence of Leibniz’ approach, we should distinguish these principles more sharply than he himself did and pay more attention to their status : are they consequences of the definition of motion, consequences of the physical laws or necessary conditions for any physical theory?

This book explores new findings on the long-neglected topic of theory construction and discovery, and challenges the orthodox, current division of scientific development into discrete stages: the stage of generation of new hypotheses; the stage of collection of relevant data; the stage of justification of possible theories; and the final stage of selection from among equally confirmed theories. The chapters, written by leading researchers, offer an interdisciplinary perspective on various aspects of the processes by which theories rationally should, and descriptively (...) are, built. They address issues such as the role of problem-solving and heuristic reasoning in theory-building; how inferences and models shape the pursuit of scientific knowledge; the relation between problem-solving and scientific discovery; the relative values of the syntactic, semantic, and pragmatic view of theories in understanding theory construction; and the relation between ampliative inferences, heuristic reasoning, and models as a means for building new theories and knowledge. Through detailed arguments and examinations, the volume collectively challenges the orthodox view’s main tenets by characterizing the ways in which the different “stages” are logically, temporally, and psychologically intertwined. As a group, the chapters provide several attempts to answer long-standing questions about the possibility of a unified conceptual framework for building theories and formulating hypotheses. (shrink)

We do so by issuing two skeptical challenges to design-deniers. The first challenge draws inspiration from radical skepticism (...) and shows how design claims are at least as compelling as radical skeptical scenarios in undermining knowledge claims, and in fact probably more so. The second challenge takes its cue from skeptical theism and shows how we are typically not in an epistemic position to rule out design. (shrink)

Le présent article traite des origines de la théorie de la catégorisation, telle qu’elle fut élaborée par Eleanor Rosch dans les années 1970. Il est divisé en deux parties. La première est consacrée au contexte théorique dans lequel les recherches initiales de Rosch ont pris place. Pour bien comprendre ce contexte, il convient de remonter aux recherches de Lenneberg et de ses coauteurs sur le principe de relativité de Whorf. On retracera ainsi le cheminement qui mena de ce principe jusqu’à (...) sa reformulation comme hypothèse empiriquement testable, en partant des études sur la catégorisation des couleurs (menées à l’université de Harvard) pour en arriver à la publication de l’ouvrage de Berlin et Kay sur les termes de couleurs de base. Pour des raisons que nous tenterons d’expliciter, au relativisme initial se substitua une forme d’universalisme auquel le livre de Berlin et Kay apporta une contribution non négligeable. La seconde partie narre le développement de la théorie de Rosch au sein de ce contexte universaliste. En étendant progressivement sa théorie au-delà de ses objets initiaux (les couleurs et les formes spatiales) pour embrasser les catégories dites “sémantiques”, Rosch évolua d’une conception “analogique” ou gestaltiste de la catégorie vers une analyse en termes d’attributs discrets. Son concept de prototype incorporait initialement des traits qui venaient de la Gestalttheorie et de la notion de schéma (telle qu’elle avait été opérationnalisée en psychologie après Bartlett), pour devenir ensuite plus complexe. Tout au long de cette évolution, elle conserva une approche réaliste de la catégorie, entendue comme un agrégat “naturel” de propriétés. Pour étayer son réalisme, elle recourut à des outils théoriques forgés avant elle par Egon Brunswik (à qui elle est redevable de son index de validité de l’indice) et par Garner, à qui elle a emprunté la notion de structurelle corrélationnelle, notion issue d’une théorie informationnelle de la catégorisation. Quant à sa conception des niveaux de catégorisation, et notamment du “niveau de base”, elle doit beaucoup aux travaux de Brent Berlin sur les taxinomies populaires. Il est possible aussi que Rosch ait subi l’influence de Roger Brown, du moins en ce qui concerne les schémas d’action associés à des objets. Ainsi, la théorie de Rosch constitue un “patchwork conceptuel” qui a acquis cohérence et unité en intégrant des éléments d’origines variées. (shrink)

ABSTRACT: In this paper I argue (i) that the hypothetical arguments about which the Stoic Chrysippus wrote numerous books (DL 7.196) are not to be confused with the so-called hypothetical syllogisms" but are the same hypothetical arguments as those mentioned five times in Epictetus (e.g. Diss. 1.25.11-12); and (ii) that these hypothetical arguments are formed by replacing in a non-hypothetical argument one (or more) of the premisses by a Stoic "hypothesis" or supposition. Such "hypotheses" or suppositions differ from propositions in (...) that they have a specific logical form and no truth-value. The reason for the introduction of a distinct class of hypothetical arguments can be found in the context of dialectical argumentation. The paper concludes with the discussion of some evidence for the use of Stoic hypothetical arguments in ancient texts. (shrink)

Ever since ecology's inception, the concept of competition has generated discussion. Recent discussions have focused on the role of interspecific competition in shaping the structure of ecological communities. More in particular, ecologists are split up over the validity of a method that is currently in vogue to discredit explanations of community structure in terms of competition theory. An analysis of this controversy is presented which attempts to show that the discussions so far have focused on the wrong issues. Not the (...) method's ability to generate alternative explanations should be questioned, but its ability to generate superior explanations. The impact of Popperian philosophy of science on the dispute is briefly discussed. (shrink)

ArgumentThis paper investigates whether there is a discrepancy between stated and actual aims in biomechanical research, particularly with respect to hypothesis testing. We present an analysis of one hundred papers recently published inThe Journal of Experimental BiologyandJournal of Biomechanics, and examine the prevalence of papers which have hypothesis testing as a stated aim, contain hypothesis testing claims that appear to be purely presentational, and have exploration as a stated aim. We found that whereas no papers had exploration as a stated (...) aim, 58 per cent of papers had hypothesis testing as a stated aim. We had strong suspicions, at the bare minimum, that presentational hypotheses were present in 31 per cent of the papers in this latter group. (shrink)

The purpose of the study was to analyze the coherence of the presentation of hypotheses and conclusions in postgraduate thesis on educational quality, which was carried out with a descriptive design. The population consisted of postgraduate theses on educational quality from four Universities of Lima, supported from 2020 to 2022, and the sample was adequate and representative. After the documentary review and analysis, the statistical analysis allowed us to find as a result a weak linear positive correlation of such variables (...) with a significance much lower than 0.01, which means that there is no optimal logical articulation between elements of the these.
