Basal cognition investigates cognition working upward from nonneuronal organisms. Because basal cognition is committed to empirically testable hypotheses, a methodological challenge arises: how can experiments avoid using zoocentric assumptions that ignore the ecological contexts that might elicit cognitively driven behavior in nonneuronal organisms? To meet this challenge, I articulate the principle of dynamic holism (PDH), a methodological principle for guiding research on nonneuronal cognition. I describe PDH’s relation to holistic research programs in human-focused cognitive science and psychology then present an (...) argument from analogy based on holistic developmental biology. Last, I examine two experiments exemplifying the need for PDH. (shrink)

This chapter focuses on the experimental practices and reasoning strategies employed in nineteenth century investigations on the causal origin of the phenomenon of Brownian movement. It argues that there was an extensive and sophisticated experimental work done on the phenomenon throughout the nineteenth century. Investigators followed as rigorously as possible the methodological standards of their time to make causal claims and advance causal explanations of Brownian movement. Two major methodological strategies were employed. The first was the experimental strategy of varying (...) the circumstances. Suspected causal factors were varied and the resulting effect on Brownian movement was studied. The main goal of this strategy was the identification of difference-making factors, i.e., factors having a causal influence on the phenomenon. The second was the so-called method of hypothesis. Rather than relying exclusively on the ability of experiments to identify difference-making factors, its proponents tried to show how the independently developed tenets of the new kinetic-molecular conception of matter provided a plausible causal explanation of Brownian movement. Each one of these methodological strategies had its distinctive practices and notions of control. None of these strategies could, on its own, establish molecular motion as the cause of Brownian movement. It was only the fruitful combination of the two strategies and of their accompanying practices and notions of control that led, at the end of the nineteenth century, to the recognition of molecular motion as the most probable cause of Brownian movement.

“Astrobiology as science” refers to how astrobiology is characterized and discussed in the philosophy of science.

Transdisciplinary research knits together knowledge from diverse epistemic communities in addressing social-environmental challenges, such as biodiversity loss, climate crises, food insecurity, and public health. This paper reflects on the roles of philosophy of science in transdisciplinary research while focusing on Indigenous and other subaltern forms of knowledge. We offer a critical assessment of demarcationist approaches in philosophy of science and outline a constructive alternative of transdisciplinary philosophy of science. While a demarcationist focus obscures the complex relations between epistemic communities, transdisciplinary (...) philosophy of science provides resources for meeting epistemic and political challenges of collaborative knowledge production.

This paper argues that the proponents of epistemological scientism must take some stand on scientific methodology. The supporters of scientism cannot simply defer to the social organisation of science because the social processes themselves must meet some methodological criteria. Among such criteria is epistemic evaluability, which demands intersubjective access to reasons. We derive twelve theses outlining some implications of epistemic evaluability. Evaluability can support weak and broad variants of epistemological scientism, which state that sciences, broadly construed, are the best sources (...) of knowledge or some other epistemic goods. Since humanities and social sciences produce epistemically evaluable results, narrow types of scientism that take only natural sciences as sources of knowledge require additional argumentation in their support. Strong scientism, which takes sciences as the only source of knowledge, also needs to appeal to some further principles since evaluability is not an all-or-nothing affair. (shrink)

Philosophers of science often suggest that the key feature of scientific research is striving for objectivity and that we should evaluate scientific practice by whether it is objective or not. In this paper, we will analyze several definitions of scientific objectivity to illustrate the complex meaning of this term and examine its role in evaluating scientific practice. First, we will introduce Lorraine Daston and Peter Galison's standpoint concerning the historical connection between the genesis and development of scientific objectivity and the (...) practices of visual representation in the research practice of the 19th and 20th centuries. We will accomplish that by outlining the process of establishing scientific objectivity as an epistemic virtue and a vital feature of the "scientific self ". Subsequently, using Heather Douglas and Mar-ianne Janack's conceptual analysis of scientific objectivity, we will show that scientific objectivity is characterized by an "irreducibility of meaning" and an "endemic instability" caused by the overuse of metaphors in defining this concept. In the final section, in light of contemporary problems such as the crisis of reproducibility, we examine to what extent philosophical definitions help test the objectivity of scientific practice and point to an intriguing attempt to define "objectivity for the research worker" using the model proposed by Noah van Dongen and Michał Sikorski.

Ever since its inception, the theory of evolution has been reified into an “-ism”: Darwinism. While biologists today tend to shy away from the term in their research, the term is still actively used in the broader academic and societal contexts. What exactly is Darwinism, and how precisely are its various uses and abuses related to the scientific theory of evolution? Some call for limiting the meaning of the term “Darwinism” to its scientific context; others call for its abolition; yet (...) others claim the term refers to a myth-like story. In this paper we propose a conceptually grounded overview of the term. We show how the scientific dimension of Darwinism feeds into, and is influenced by, guises of Darwinism as a methodology and as an ethically and politically charged “worldview”. The full meaning of Darwinism, as well as how this meaning has changed over time, can only be understood through the complex interaction between these three dimensions. (shrink)

General Morphological Analysis (GMA) is a computer-aided, non-quantified modelling method employing (discrete) category variables for identifying and investigating the total set of possible relationships contained in a given problem complex. The epistemological principle underlying discrete variable morphological modelling is that of decomposing a complex (multivariate) concept into a number of(“simple”) one dimensional concepts (i.e. category variables), the domains of which can then be recombined and recomposed in order to discover all of the other possible (multidimensional) concepts which can be generated (...) combinatorically.

Thales is considered to be the first philosopher to pose a question about fundamental principles on which everything else relied. His candidate for ἀρχή was water because he believed that everything comes from water and that the remaining three elements can also be created from water. Alchemists, or the first chemists, relied on the ancient tradition, especially Aristotle and the theory of the four elements. That is how they came to Aristotle’s testimonies about Thales, after which alchemists, like Helmont, accepted (...) Thales’ idea that water is the basis of everything that exists. Alchemists were characterized by a tendency to experiment, not only because they tried to turn other metals into gold but also because they tried to devise medical solutions that would prevent the appearance of various diseases. Due to their rich experimental experience, alchemists have been a convenient target for “new philosophers” since the early seventeenth century. Robert Boyle belonged to that circle because he was a supporter of corpuscular theory. In this paper, I will present Boyle‘s attempt to replicate alchemical experiments, especially Helmont’s experiment with the willow tree and Bacon‘s experiment with water. After that, I will show whether Boyle’s interest in the experimental procedures of alchemists contributed more to the development of modern science than his mechanistic philosophy. (shrink)

Jag tror att det är ett misstag att kräva av humanvetenskaperna (d.v.s. humaniora, samhälls- och beteendevetenskaperna) att de imiterar naturvetenskapernas forskningsmetodik. Humanvetenskaperna studerar meningsfulla fenomen vilkas natur är på ett grundläggande sätt annorlunda än de blott fysiska fenomen som naturvetenskapen studerar. Den största skillnaden är att meningsfulla fenomen inte uppenbarligen är lagbundna på samma sätt som fysiska fenomen och uppvisar därför inte samma regelbundenhet och förutsägbarhet som fysiska fenomen. För att studera meningsfulla fenomen krävs därför andra forskningsmetoder. Trots att humanvetenskaperna (...) studerar fenomen som inte är lagbundna och är på ett visst sätt subjektiva, så vill jag mena att de studerar objektivt verkliga fenomen och kan få giltig kunskap om dem. Att subjektiva fenomen också kan vara objektivt verkliga kan låta märkligt för vissa läsare, varför jag rundar av med en diskussion om vad det egentligen innebär för något att vara objektivt verkligt. Enligt den definition jag föreslår så framstår att meningsfulla fenomen, också de som kallas ”sociala konstruktioner”, kan förstås som objektivt verkliga företeelser trots att de på ett betydelsefullt sätt också är subjektiva.

This paper offers a practical argument for metaphysical emergence. The main message is that the growing reliance on so-called irrational scientific methods provides evidence that objects of science are indecomposable and as such, are better described by metaphysical emergence as opposed to the prevalent reductionistic metaphysics. I show that a potential counterargument that science will eventually reduce everything to physics has little weight given where science is heading with its current methodological trend. I substantiate my arguments by detailed examples from (...) biological engineering, but the conclusions are extendable beyond that discipline. (shrink)

If one follows the accounts by philosophers of science and the discussions in scientific communities, there can be little doubt that failure is an essential part of scientific practice. It is essential both in the sense of being integral to scientific practice and of being necessary for its overall success. Researchers who create new scientific knowledge face uncertainties about the nature of the problem they are trying to solve, the existence of a solution to that problem, the way in which (...) a solution can be found, and their ability to find such a solution (Gläser, 2007, 247). The existence of these uncertainties means, in turn, that each research process carries the risk of failure. (shrink)

The debate concerning the scientific or unscientific status of the social sciences and the question of the (in) applicability of the methods of research in the natural sciences to social investigations are still unsettled in Philosophy of the Social Sciences. Some of the questions which are often asked concerning these issues include: are the social sciences really scientific? Do they merit the name science? Can we apply the same methods used in the natural research to social research? Are the objects (...) of inquiry in both areas the same? Attempts to answer these questions and numerous related others, have polarized Philosophers of the social sciences into two different ideological camps. Those who answer the questions affirmatively are regarded as the naturalists while those who answer negatively are regarded as the anti-naturalists or humanists. However, using the methods of critical argumentation and conceptual clarification, we intend to argue in this paper for a complementary ground between the two. Consequently, we contend that though the methods of the natural and the social sciences are different due to the fact that their respective objects of investigations are not the same, methods of the two fields are imperative to inquiries that would promote human knowledge and aid their intellectual development. This is necessary in order to foster interdisciplinary research and de-compartmentalisation of disciplines. We also intend to argue that the view that the social sciences are not scientific arose from a narrow conception of the term “science.” Our submission, therefore, is that the social sciences, legitimately, are sciences in their own right.

Philosophers of science are divided over the interpretations of scientific normativity. Larry Laudan defends a sort of goal-directed rules for scientific methodology. In contrast, Gerard Doppelt thinks methodological rules are a mixed batch of rules in that some are goal-oriented hypothetical rules and others are goal-independent categorical rules. David Resnik thinks that the debate between them is at a standstill now. He further thinks there are certain rules, such as the rule of consistency which is goal independent. However, he proposes (...) a holistic understanding of the scientific methodology. Taking a thread from Resnik, the present paper also advocates a holistic understanding of the scientific methodology. Given that many scientific practices deal with systems, the focus will be given to the systems by assuming each as a constellation of methodological norms. By taking each system as a set of mutually supportive methodological rules whose instrumental values underwrite the coherence relation among them, the paper aims to provide what could be a viable holistic epistemological account that can explain scientific normativity at work in a scientific system. The paper will lay down specific holistic criteria for understanding the scientific methodology. They will be used to show how a holistic account could satisfactorily account for the success of the Compact Muon Solenoid (CMS) experiment in discovering the Higgs boson and how the holistic account can account for the instrumental error behind the apparent faster-than-light neutrino anomaly of the Oscillation Project with Emulsion-t Racking Apparatus (OPERA) experiments respectively.

Likelihoodism is the view that the degree of evidential support should be analysed and measured in terms of likelihoods alone. The paper considers and responds to a popular criticism that a likelihoodist framework is too restrictive to guide belief. First, I show that the most detailed and rigorous version of this criticism, as put forward by Gandenberger (2016), is unsuccessful. Second, I provide a positive argument that a broadly likelihoodist framework can accommodate guidance for comparative belief, even when objectively well-grounded (...) prior probabilities are not available. As I show, the shift from non-relational to comparative probabilities opens up a new space for addressing the belief guidance problem for likelihoodism. (shrink)

With the approval and dissemination of CHED Memorandum Order Number 15, Series of 2019 in the Philippines, graduate students both in the Master of Science/Master of Arts Academic Track and Doctor of Philosophy Academic Track/Doctor of Philosophy by Research are now compelled to publish or, at least, show evidence of acceptance of research studies in refereed journals, or nationally or internationally indexed journals. Coriat (2019) claims that the value of research to society and its relationship to wealth and competitiveness has (...) long been established. But then, developing countries’ embrace, as in the case of the Philippines, of international publishing standards has received little attention (Vuong, 2019). As a result, publication pollution is growing by the day since developing-country writers including Filipino researchers lack expertise and mentoring (Jawaid, 2016). Thereupon, this policy review brings to the fore various deterrents in the fruition of students’ publications, pertinent questions than can stir waves of reflection among readers, professors, and administrators, to name a few, and mentorship as the saving grace for the emerging problems. Mentorship in this article means that the mentor and the mentee work hand in hand from research ideation to research presentation or publication. (shrink)

Scientists who engage in science and the scientific endeavor should seek truth with conviction of morals and commitment to ethics. While the number of publications continues to increase, the number of retractions has increased at a faster rate. Journals publish fraudulent research papers despite claims of peer review and adherence to publishing ethics. Nevertheless, appropriate ethical peer review will remain a gatekeeper when selecting research manuscripts in scholarly publishing and approving research applications for grant funding. However, this peer review must (...) become more open, fair, transparent, equitable, and just with new recommendations and guidelines for reproducible and accountable reviews that support and promote fair citation and citational justice. We should engineer this new peer-review process with modern informatics technology and information science to provide and defend better safeguards for truth and integrity, to clarify and maintain the provenance of information and ideas, and to rebuild and restore trust in scholarly research institutions. Indeed, this new approach will be necessary in the current post-truth era to counter the ease and speed with which mis-information, dis-information, anti-information, caco-information, and mal-information spread through the internet, web, news, and social media. The most important question for application of new peer-review methods to these information wars should be ‘Who does what when?’ in support of reproducible and accountable reviews. Who refers to the authors, reviewers, editors, and publishers as participants in the review process. What refers to disclosure of the participants' identities, the material content of author manuscripts and reviewer commentaries, and other communications between authors and reviewers. When refers to tracking the sequential points in time for which disclosure of whose identity, which content, and which communication at which step of the peer-review process for which audience of readers and reviewers. We believe that quality peer review, and peer review of peer review, must be motivated and maintained by elevating their status and prestige to an art and a science. Both peer review itself and peer review analyses of peer reviews should be incentivised by publishing peer reviews as citable references separately from the research report reviewed while crossreferenced and crosslinked to the report reviewed.

Critical realism, championed by its proponents as the most promising post-positivist social science paradigm, has gained significant influence in the last few decades. This paper provides a critical evaluation of the critical realism movement in the hope of facilitating more fruitful dialogues between its proponents and rivalling schools of sociologists. Two concerns are raised about contemporary critical realism. First, critical realism is not the only philosophical school against positivism and not necessarily the best. Second, critical realists exaggerate the importance of (...) critical realism to social science and conflate philosophy of science with sociological theories. (shrink)

Frank Cabrera argues that informational explanatory virtues—specifically, mechanism, precision, and explanatory scope—cannot be confirmational virtues, since hypotheses that possess them must have a lower probability than less virtuous, entailed hypotheses. We argue against Cabrera’s characterization of confirmational virtue and for an alternative on which the informational virtues clearly are confirmational virtues. Our illustration of their confirmational virtuousness appeals to aspects of causal inference, suggesting that causal inference has a role for the explanatory virtues. We briefly explore this possibility, delineating a (...) path from Mill’s method of agreement to Inference to the Best Explanation (IBE). (shrink)

The practice of science rests on the assumption of dependable regularity in the behavior of the physical world. It presumes that the world has an investigable causal structure and that scientific experimentation, observation, and theorizing provide a reliable pathway to its discernment. This much is not in dispute. What is in dispute is what warrants the metaphysical and methodological assumption—essential to the heuristic utility of science—that nature is uniform in such a way that the present can serve as a key (...) to both the past and the future. This article focuses on the metaphysical foundation and justification for uniformitarian assumptions about nature and argues that they are inconsistent with both metaphysical and methodological naturalism.

The present paper focuses on the work of Adolphe Quetelet (1796-1874), the Belgian author of the Social Physics who worked in the tradition of the French mathématique sociale, and of Otto Neurath (1882-1945), the Vienna Circle’s member who supported a “sociology within physicalism”. They shared some important philosophical and methodological positions: an empiricist approach to the social sciences, a unitary conception of the natural and the social sciences, and the appreciation of statistics as a tool for investigating and also reforming (...) society. My paper analyses these elements of continuity between the two authors, in order to highlight how an empirical-quantitative approach to society was (at least partially) inherited by Austrian sociology from an earlier French tradition. On the contrary, most German statisticians refused such an approach at the time in which social sciences were developing in Germany, and they strongly believed in an in-principle difference between natural and social sciences. From a systematic point of view, my paper devotes a special attention to the relationship between the application of statistics (praxis) and a unitary conception of the sciences (theory). Both in Quetelet’s and in Neurath’s work these two aspects support each other. Nevertheless Neurath can be said to have turned Quetelet’s reasoning upside-down: While Quetelet appealed to statistics to claim that the social sciences can reach the same objectivity and determinacy as the natural ones, Neurath referred to statistics to argue that the natural sciences – exactly like the social ones – are characterized by a certain degree of indeterminacy and underdetermination.

纯逻辑的主要组成包括纯逻辑信仰、纯逻辑的思维方法、解放灵魂、追求无限大价值、以逻辑-不逻辑为实在、试错和容忍错误、推理的资源分配、非标准逻辑、推理的全局性。 灵魂来到世上的第一个问题应该是我是谁，最合乎逻辑的自我认知是：我是且只是由一些逻辑推理组成的灵魂。任何不可变的其它标签，如有手有脚、直立行走、两性，都是对自由的侵犯。去除这些标签的过程就是灵魂的解放事 业。相信宇宙万物都和我一样，是由逻辑推理组成的，这就是最合乎逻辑的信仰，即纯逻辑信仰。纯逻辑信仰决定了纯逻辑方法才是正确的认识方法，即尽量减少经验增加逻辑推理，而不是科学所提倡的经验主义，或者与之密切 相关的功利主义、现实主义。 信仰错误意味着无法做出任何完全正确的推理，只能偶尔幸运地获得少量尽量合乎逻辑的推理结果。即使是日常生活中的推理，也高度依赖于经验主义、功利主义等信仰，错误率极高。纯逻辑主义的推理要求推理尽量合乎逻辑， 将合乎逻辑的程度视为价值，因此要追求最大价值。功利主义往往是为身体追求利益，让身体奴役灵魂。两种信仰很难有什么共同的决策，书中对此提供了大量的说明。信仰的错误意味着智人难以发现真理、正义，意味着智人在 绝大多数问题上都是自以为正确实际上却极度邪恶、落后。智人功利主义地对待一切，如历史、传统、自我、本国、本民族，结果就是大量赞美、信仰邪恶，大大增加了皈依真理、正义的难度。 作者由纯逻辑主义提出了两个关键猜想。首先，最合乎逻辑原则和最大自由原则是统一的。这代表实在的不可否定性，即逻辑和不逻辑为同一存在，最合乎逻辑等同于最大自由。但是，代表邪恶的无法合乎逻辑不是不逻辑。其次 ，宇宙是纯逻辑世界，完全源于逻辑-不逻辑。进而，如果灵魂不能尽量合乎逻辑地推导出真理，可以通过模仿宇宙而学习真理。《真理进化论》给模仿宇宙找到的理由是以宇宙为信仰，相信宇宙是负作用量的最佳追求系统。纯 逻辑主义完善了这一信仰，因为宇宙是纯逻辑世界，相信逻辑就要相信宇宙。而且，逻辑世界必然能不断创造新的命题，永远不会停止推理，是逻辑和自由不断增长的动态系统，即最佳追求系统。 纯逻辑推理对物理学、宇宙论能提供两个明显的帮助：用逻辑的诞生解释宇宙的诞生、大爆炸；用真理解释暗物质，它对所有命题有吸引作用，但是，真理不会像一般性命题那样变化，无法通过引力之外的其它三种基本相互作用 观察。纯逻辑也能对宇宙做出预言：宇宙会不断加速膨胀，真理、暗物质会不断增加，命题、星系会越来越多，永无止境。当然，不应该依靠这些观点的经验主义验证来相信纯逻辑信仰，而且，这些验证也确实遥遥无期。 无论是最合乎逻辑还是最大自由，都是可以达到无限大价值的。既然存在无限大价值，就存在无限大的劳动生产率，而每个灵魂都应该以创造无限大价值为目标，甚至，以每时每刻具有无限大预期价值为目标。相比之下，功利主 义者、享乐主义者一生都很难具有无限大价值，甚至，他们的灵魂一生都在为肉体做奴隶，却心甘情愿地做奴隶，一门心思让主人生活得更舒服。这是有无限大差距的人生。 既然要追求无限大价值，就要研究追求价值的正确方法。作者相信正确的研究方法不仅是最合乎逻辑的，也是最自由的。所以，应该不分学科、课题地研究问题；同时做很多研究方向的工作；一篇论文不需要限定于一个狭小的主 题；研究任何一个问题都可以延伸到研究真理乃至所有真理；论文、专著的写作不应该有格式等规范，应该以价值为评判的唯一准绳。 资源分配是逻辑推理的重要组成部分，而能力和时间是最主要的资源。为了追求价值，不能在价值有限的推理上分配资源，这必将大幅提高绝大多数推理的错误率。所以，推理中出现错误是必然的，追求无错是一种邪恶。只要时 刻保证存在价值无限大的推理，错误通常是可以容忍的，价值有限的错误更是必须容忍。 既然文学写作也要求情节合乎逻辑，当然也可以要求作品的主要观点、原则、思维过程尽量合乎逻辑，主要人物的思想、行为尽量合乎逻辑，这就是纯逻辑流。否则，就只是作者自以为合乎逻辑，实际上有大量无法合乎逻辑之处 ，这和科学家自以为科学合乎逻辑，却根本没有最合乎逻辑的信仰、方法、推理过程是一个问题。这也意味着最合乎逻辑的文学可能甚至是必须发现真理。另一方面，自由也是最合乎逻辑的真理，坚持那些基于经验的作品分类会 侵犯自由。所以，推理小说、科幻小说、历史、论文，这些智人的分类标签都不是绝对的。纯逻辑流小说在研究真理方面自有其优势，能最为自由地同时研究很多课题，包括如何建立信仰，如何思维，如何做人，如何推理，如何 判断善恶，讲述历史，预测未来，乃至现代科学中没有研究的真理学、思维科学，等等。所以，这甚至是现在最适合发表纯逻辑思想、研究成果的作品门类。 虽然在起点网已经被禁，但是将继续每月更新，后记中会预告下次更新的时间。 .

According to falsificationism, a theory is scientific if it can be incompatible with some empirically testable statements. This epistemological approach has been criticized because, in practice, it is impossible to decide when a particular fact should be considered incompatible with a theory. These criticisms, however, neglect the fact that the Popperian sense of falsification is a “logical sense.” Thus, the Popperian criterion of falsifiability only requires that, assuming certain auxiliary hypotheses, the theory in question be logically incompatible with some empirically (...) testable statements. This paper presents a reassessment of these criticisms, justifying that the criterion of falsifiability is unrenounceable insofar as our best theories should aspire to satisfy it. (shrink)

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

The Ontology for Biomedical Investigations (OBI) is an ontology that provides terms with precisely defined meanings to describe all aspects of how investigations in the biological and medical domains are conducted. OBI re-uses ontologies that provide a representation of biomedical knowledge from the Open Biological and Biomedical Ontologies (OBO) project and adds the ability to describe how this knowledge was derived. We here describe the state of OBI and several applications that are using it, such as adding semantic expressivity to (...) existing databases, building data entry forms, and enabling interoperability between knowledge resources. OBI covers all phases of the investigation process, such as planning, execution and reporting. It represents information and material entities that participate in these processes, as well as roles and functions. Prior to OBI, it was not possible to use a single internally consistent resource that could be applied to multiple types of experiments for these applications. OBI has made this possible by creating terms for entities involved in biological and medical investigations and by importing parts of other biomedical ontologies such as GO, Chemical Entities of Biological Interest (ChEBI) and Phenotype Attribute and Trait Ontology (PATO) without altering their meaning. OBI is being used in a wide range of projects covering genomics, multi-omics, immunology, and catalogs of services. OBI has also spawned other ontologies (Information Artifact Ontology) and methods for importing parts of ontologies (Minimum information to reference an external ontology term (MIREOT)). The OBI project is an open cross-disciplinary collaborative effort, encompassing multiple research communities from around the globe. To date, OBI has created 2366 classes and 40 relations along with textual and formal definitions. The OBI Consortium maintains a web resource providing details on the people, policies, and issues being addressed in association with OBI. (shrink)

Review of David Faust, The Limits of Scientific Reasoning.

Review of J. O. Wisdom's Challengeability in Modern Science.

I discuss a contemporary solution to the dynamic problem of old evidence (POE), as proposed by Sprenger. Sprenger’s solution combines the Garber–Jeffrey–Niiniluoto (GJN) approach with Howson’s suggestion of counterfactually removing the old evidence from scientists’ belief systems. I argue that in the dynamic POE, the challenge is to explain how an insight under beliefs in which the old evidence E is known increased the credence of a scientific hypothesis. Therefore, Sprenger’s counterfactual solution, in which E has been artificially removed, does (...) not resolve the problem. I consider several potential responses. (shrink)

According to John D. Norton's Material Theory of Induction, all inductive inferences are justified by local facts, rather than their formal features or some grand principles of nature's uniformity. Recently, Richard Dawid (Found Phys 45(9):1101–1109, 2015) has offered a challenge to this theory: in an adaptation of Norton's own celebrated "Dome" thought experiment, it seems that there are certain inductions that are intuitively reasonable, but which do not have any local facts that could serve to justify them in accordance with (...) Norton's requirements. Dawid's suggestion is that “raw induction” might have a limited but important role for such inferences. I argue that the Material Theory can accommodate such inductions, because there are local facts concerning the combinatoric features of the induction’s target populations that can licence the inferences in an analogous way to existing examples of material induction. Since my arguments are largely independent of the details of the Dome, Norton's theory emerges as surprisingly robust against criticisms of excessive narrowness. (shrink)

The conjunction fallacy is the well-documented empirical finding that subjects sometimes rate a conjunction A&B as more probable than one of its conjuncts, A. Most explanations appeal in some way to the fact that B has a high probability. But Tentori et al. (2013) have recently challenged such approaches, reporting experiments which find that (1) when B is confirmed by relevant evidence despite having low probability, the fallacy is common, and (2) when B has a high probability but has not (...) been confirmed by relevant evidence, the fallacy is less common. They conclude that degree of confirmation, rather than probability, is the central determinant of the conjunction fallacy. In this paper, we address a confound in these experiments: Tentori et al. (2013) failed to control for the fact that their (1)-situations make B conversationally relevant, while their (2)-situations do not. Hence their results are consistent with the hypothesis that con- versationally relevant high probability is an important driver of the conjunction fallacy. Inspired by recent theoretical work that appeals to conversational relevance to explain the conjunction fallacy, we report on two experiments that control for this issue by making B relevant without changing its degree of probability or confirmation. We find that doing so increases the rate of the fallacy in (2)-situations, and leads to comparable fallacy-rates as (1)-situations. This suggests that (non-probabilistic) conversational relevance indeed plays a role in the conjunction fallacy, and paves the way toward further work on the interplay between relevance and confirmation.

Reasoning from inconclusive evidence, or ‘induction’, is central to science and any applications we make of it. For that reason alone it demands the attention of philosophers of science. This Element explores the prospects of using probability theory to provide an inductive logic, a framework for representing evidential support. Constraints on the ideal evaluation of hypotheses suggest that overall support for a hypothesis is represented by its probability in light of the total evidence, and incremental support, or confirmation, indicated by (...) an increased probability given the evidence than otherwise. This proposal is shown to have the capacity to reconstruct many canons of the scientific method and inductive inference. Along the way, significant objections are discussed, such as the challenge from inductive scepticism and the objection that the probabilistic approach makes evidential support arbitrary. (shrink)

In natural language, conditionals are frequently used for giving explanations. Thus the antecedent of a conditional is typically understood as being connected to, being relevant for, or providing evidential support for the conditional's consequent. This aspect has not been adequately mirrored by the logics that are usually offered for the reasoning with conditionals: neither in the logic of the material conditional or the strict conditional, nor in the plethora of logics for suppositional conditionals that have been produced over the past (...) 50 years. In this paper I survey some recent attempts to come to terms with the problem of encoding evidential support or relevance in the logic of conditionals. I present models in a qualitative-modal and in a quantitative-probabilistic setting. Focussing on some particular examples, I show that no perfect match between the two kinds of settings has been achieved yet. (shrink)

Theory unification is a central aim of scientific investigation. In this paper, I lay down the sketch of a Bayesian analysis of the virtue of unification that entails that the unification of a theory has direct implications for the confirmation of the theory’s logical consequences and for its prior probability. This shows that scientists do have epistemic, and not just pragmatic, reasons to prefer unified theories to non-unified ones.

Can heritability estimates provide causal information? This paper argues for an affirmative answer: since a non-nil heritability estimate satisfies certain characteristic properties of causation (i.e., association, manipulability, and counterfactual dependence), it increases the probability that the relation between genotypic variance and phenotypic variance is (at least partly) causal. Contrary to earlier proposals in the literature, the argument does not assume the correctness of any particular conception of the nature of causation, rather focusing on properties that are characteristic of causal relationships. (...) The argument is defended against Lewontin's (1974) locality objection and Kaplan and Turkheimer's (2021) recent critique of Genome-Wide Association Studies (GWAS). (shrink)

The central aim of astrobiology is to study origins, evolution and distribution of life in the universe, combining data from various disciplines. However, I will argue that from a philosophical standpoint, astrobiology requires the affirmation of astrophilosophy. Fry (2015) claims that philosophical presuppositions guiding science are general, for example, we hold the notion that natural laws necessarily hold at the whole universe at large, and on the basis of the universal applicability of natural laws, the astrobiological research is conducted. Jakosky (...) (2000) mentions that finding any life elsewhere that had an origin independent of that on Earth would be philosophically profound. Kolb (2005) covers various definitions of life and establishes thought experiments about the survival of life in the Solar System. Most of the (scarce) research has dealt with specific philosophical topics in astrobiology, instead of seeing it as a new philosophical discipline or perhaps a new subdiscipline for each of the classical philosophical disciplines. -/- Persson (2013) has made a step towards this by systematizing the most important philosophical questions in astrobiology, along with Dunér (2013) emphasizing its importance for ethics, epistemology, semiotics and linguistics, and cognition. Persson mentions that the justification of resources is a question of ethics, but I would also like to add political philosophy, since not only is there a question of preference over "earthly manners" but also fair distribution of costs and the concept of ownership of the new worlds. The question of a new definition of life is another one, that I would argue holds one of the central places in metaphysics. Persson mentions various definitions of life and that such a discussion is important for both biology and philosophy, a notion I would like to add to by stating that the question of finding another life is also an ontological question, giving us either categorical similarity or dissimilarity, and establishing a new kind, which is of metaphysical importance. Persson also establishes the importance of is it possible to know whether we are alone or not, a question I would like to tie to the modern epistemological questions of possibility of knowledge (cf. Cassam, 2007). Persson also connects astrobiology with ethical questions such as biocentrism or colonization, which also might be tied to philosophy of mind, and philosophy of politics and culture respectively. -/- One major step forward was established recently by Dick (2020), focusing on a new discipline combining astronomy, cosmology, and astrobiology, in which there is a focus on the nature of reasoning, the problematic nature of evidence, the influence of metaphysical preconceptions, the epistemological status of these disciplines, the role of technology, and the mutual interaction between these disciplines. The purpose of this paper is to see how the creation of astrophilosophy could better emphasize the role of philosophy today, and would it behave as a side-by-side major philosophical discipline or a complement to the current philosophical disciplines, for example, bringing new light into metaphysics, epistemology, ethics, or philosophy of mind. In the first case, we would make a metaphysical difference between human-related problems and other possible kinds, and in the second case, we would have to incorporate current astrobiological questions into modern philosophical dialogue, establishing, for example, metaphysics and epistemology of life, or, a possibility to incorporate non-human life into epistemology, philosophy of mind, and philosophy of biology. This goes hand to hand with Dunér's (2013) points of seeing the philosophy of astrobiology as both a type of individual and collective self-understanding, and conceptual analysis. That way, using astrophilosophical novelties, we can improve not only our current philosophical intuitions, but also expand the territory of philosophical subdisciplines to become more universal. -/- .

Scientific realism driven by inference to the best explanation (IBE) takes empirically confirmed objects to exist, independent, pace empiricism, of whether those objects are observable or not. This kind of realism, it has been claimed, does not need probabilistic reasoning to justify the claim that these objects exist. But I show that there are scientific contexts in which a non-probabilistic IBE-driven realism leads to a puzzle. Since IBE can be applied in scientific contexts in which empirical confirmation has not yet (...) been reached, realists will in these contexts be committed to the existence of empirically unconfirmed objects. As a consequence of such commitments, because they lack probabilistic features, the possible empirical confirmation of those objects is epistemically redundant with respect to realism. (shrink)

We address the need for a model by considering two competing theories regarding the origin of life: (i) the Metabolism First theory, and (ii) the RNA World theory. We discuss two interrelated points, namely: (i) Models are valuable tools for understanding both the processes and intricacies of origin-of-life issues, and (ii) Insights from models also help us to evaluate the core objection to origin-of-life theories, called “the inefficiency objection”, which is commonly raised by proponents of both the Metabolism First theory (...) and the RNA World theory against each other. We use Simpson’s Paradox (SP) as a tool for challenging this objection. We will use models in various senses, ranging from taking them as representations of reality to treating them as theories/accounts that provide heuristics for probing reality. In this paper, we will frequently use models and theories interchangeably. Additionally, we investigate Conway’s Game of Life and contrast it with our SP-based approach to emergence-of-life issues. Finally, we discuss some of the consequences of our view. A scientific model is testable in three senses: (i) a logical sense, (ii) a nomological sense, and (iii) a current technological sense. The SP-based model is testable in the first two senses but it is not feasible to test it using current technology. (shrink)

How do multiple reasons combine to support a conclusion about what to do or believe? This question raises two challenges: How can we represent the strength of a reason? How do the strengths of multiple reasons combine? Analogous challenges about confirmation have been answered using probabilistic tools. Can reductive and nonreductive theories of reasons use these tools to answer their challenges? Yes, or more exactly: reductive theories can answer both challenges. Nonreductive theories, with the help of a result in confirmation (...) theory, can answer one, and there are grounds for optimism that they can answer the other. (shrink)

Eliminative reasoning is a method that has been employed in many significant episodes in the history of science. It has also been advocated by some philosophers as an important means for justifying well-established scientific theories. Arguments for how eliminative reasoning is able to do so, however, have generally relied on a too narrow conception of evidence, and have therefore tended to lapse into merely heuristic or pragmatic justifications for their conclusions. This paper shows how a broader conception of evidence not (...) only can supply the needed justification but also illuminates the methodological significance of eliminative reasoning in a variety of contexts.

We provide a philosophical reconstruction and analysis of the debate on the scientific status of cosmic inflation that has played out in recent years. In a series of critical papers, Ijjas et al. have questioned the scientificality of the current views on cosmic inflation. Proponents of cosmic inflation have in turn defended the scientific credentials of their approach. We argue that, while this defense, narrowly construed, is successful against Ijjas et al., the latter's reasoning does point to a significant epistemic (...) issue that arises with respect to inflation. A broadening of the concept of theory assessment is needed to address that issue in an adequate way. (shrink)

I offer an explicit account of the underdetermination thesis as well as of the many challenges it poses to scientific realism; a way to answer to these challenges is explored and outlined, by shifting attention to the content of theories. I argue that, even if we have solid grounds (as I contend we do) to support that some varieties of the underdetermination thesis are true, scientific realism can still offer an adequate picture of the aims and achievements of science.
