Reductive intellectualists hold that knowledge-how is a kind of knowledge-that. For this thesis to hold water, it is obviously important that knowledge-how and knowledge-that have the same epistemic properties. In particular, knowledge-how ought to be compatible with epistemic luck to the same extent as knowledge-that. It is argued, contra reductive intellectualism, that knowledge-how is compatible with a species of epistemic luck which is not compatible with knowledge-that, and thus it is claimed that knowledge-how and knowledge-that come apart.

In this paper, we discuss three probabilistic arguments for the existence of multiple universes. First, we provide an analysis of total evidence and use that analysis to defend Roger White's "this universe" objection to a standard fine-tuning argument for multiple universes. Second, we explain why Rodney Holder's recent cosmological argument for multiple universes is unconvincing. Third, we develop a "Cartesian argument" for multiple universes. While this argument is not open to the objections previously noted, we show that, given certain highly (...) plausible assumptions about evidence and epistemic probability, the proposition which it treats as evidence cannot coherently be regarded as evidence for anything. This raises the question of whether to reject the assumptions or accept that such a proposition cannot be evidence. (shrink)

Background and aims Research into the social aspects of set and setting have demonstrated that race is a significant factor in psychedelic experiences for racially marginalized populations. Yet, many studies of psychedelic-induced experiences continue to proceed without collecting data on or considering the influence of race or other social categories. These approaches abstract subjectivity from its embodied and historical conditions, isolating consciousness in ways that do not accord with lived experience. -/- Methods This article draws on critical phenomenology, anthropology, and (...) treatments of race in the field of psychedelic studies to outline how social categories mediate subjective experience in historically specific ways through the framework of embodiment. -/- Results I argue that consciousness is fundamentally intersubjective, including during psychedelic-induced experiences. Intersubjectivity is an existential condition that makes possible meaning, communication, and socialization, processes which rely on and are perpetually (re)enacted through social categories. Therefore, studies of psychedelic-induced experiences must account for the foundational role that social categories play in constituting such embodied experiences and their effects. -/- Conclusions This approach makes embodied differences matter to the study of psychedelic-induced experiences, opening new avenues of inquiry that foreground identity, power, and context in both clinical and naturalistic research.

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。 .

This paper explores how to deliberate about food choices from a Stoic perspective informed by the value of environmental sustainability. This perspective is reconstructed from both ancient and contemporary sources of Stoic philosophy. An account of what the Stoic goal of “living in agreement with Nature” would amount to in dietary practice is presented. Given ecological facts about food production, an argument is made that Stoic virtue made manifest as wisdom, justice, courage, and temperance compel Stoic practitioners to select locally (...) sourced, low resource input, plant-based foods whenever circumstances allow.

We give a review and critique of jury theorems from a social-epistemology perspective, covering Condorcet’s (1785) classic theorem and several later refinements and departures. We assess the plausibility of the conclusions and premises featuring in jury theorems and evaluate the potential of such theorems to serve as formal arguments for the ‘wisdom of crowds’. In particular, we argue (i) that there is a fundamental tension between voters’ independence and voters’ competence, hence between the two premises of most jury theorems; (ii) (...) that the (asymptotic) conclusion that ‘huge groups are infallible’, reached by many jury theorems, is an artifact of unjustified premises; and (iii) that the (nonasymptotic) conclusion that ‘larger groups are more reliable’, also reached by many jury theorems, is not an artifact and should be regarded as the more adequate formal rendition of the ‘wisdom of crowds’.

Democratic decision-making is often defended on grounds of the ‘wisdom of crowds’: decisions are more likely to be correct if they are based on many independent opinions, so a typical argument in social epistemology. But what does it mean to have independent opinions? Opinions can be probabilistically dependent even if individuals form their opinion in causal isolation from each other. We distinguish four probabilistic notions of opinion independence. Which of them holds depends on how individuals are causally affected by environmental (...) factors such as commonly perceived evidence. In a general theorem, we identify causal conditions guaranteeing each kind of opinion independence. These results have implications for whether and how ‘wisdom of crowds’ arguments are possible, and how truth-conducive institutions can be designed. (shrink)

Inferentialism is a theory in the philosophy of language which claims that the meanings of expressions are constituted by inferential roles or relations. Instead of a traditional model-theoretic semantics, it naturally lends itself to a proof-theoretic semantics, where meaning is understood in terms of inference rules with a proof system. Most work in proof-theoretic semantics has focused on logical constants, with comparatively little work on the semantics of non-logical vocabulary. Drawing on Robert Brandom’s notion of material inference and Greg Restall’s (...) bilateralist interpretation of the multiple conclusion sequent calculus, I present a proof-theoretic semantics for atomic sentences and their constituent names and predicates. The resulting system has several interesting features: (1) the rules are harmonious and stable; (2) the rules create a structure analogous to familiar model-theoretic semantics; and (3) the semantics is compositional, in that the rules for atomic sentences are determined by those for their constituent names and predicates.

This paper provides a proof-theoretic account of imperative logical consequence by generalising Greg Restall’s multiple conclusion bilateralism for declarative logic. According to imperative bilateralism, a sequent Γ ⊢ Δ is valid iff jointly commanding all the imperatives Φ ∈ Γ and prohibiting all the imperatives Ψ ∈ Δ clashes. This account has three main virtues: (1) it provides a proof-theoretic account of imperatives; (2) it does not rely on the controversial notion of imperative inference; and (3) it is neutral regarding (...) cognitivism about imperatives.

This paper adopts the philosophical approach of Stoicism as the basis for re-examining the cognitive and ethical relationship between Homo sapiens and Neanderthals. Stoicism sets out a clear criterion for the special moral status of human beings, namely rationality. We explore to what extent Neanderthals were sufficiently rational to be considered “human”. Recent findings in the fields of palaeoanthropology and palaeogenetics show that Neanderthals possessed high-level cognitive abilities and produced viable offspring with anatomically modern humans. Our discussion offers insights for (...) reflecting on the relationship between humans and other forms of natural life and any moral obligations that result. (shrink)

This implementation framework bridges the theoretical concepts of the Instructional Modular Approach with the practical development of Science Teaching Competency. It offers prospective teachers a structured, adaptive, and technology-enhanced pathway to becoming competent and innovative science educators. Each unit is meticulously designed to not only equip teachers with theoretical knowledge but also to hone their practical skills and competencies essential for a dynamic science teaching environment.

It is a received view of the post-Fregean predicate logic that a universal statement has no existential import and thus does not entail its particular (existential) counterpart. This paper takes issue with the view by discussing the trespasser case, which has widely been employed for supporting the view. The trespasser case in fact involves a shift of context. Properly understood, the case provides no support for the received view but rather suggests that we rethink the ‘quantity view’ of the existential (...) import of quantifiers. (shrink)

The contemporary theory of epistemic democracy often draws on the Condorcet Jury Theorem to formally justify the ‘wisdom of crowds’. But this theorem is inapplicable in its current form, since one of its premises – voter independence – is notoriously violated. This premise carries responsibility for the theorem's misleading conclusion that ‘large crowds are infallible’. We prove a more useful jury theorem: under defensible premises, ‘large crowds are fallible but better than small groups’. This theorem rehabilitates the importance of deliberation (...) and education, which appear inessential in the classical jury framework. Our theorem is related to Ladha's (1993) seminal jury theorem for interchangeable (‘indistinguishable’) voters based on de Finetti's Theorem. We also prove a more general and simpler such jury theorem. (shrink)

Knowledge, like other things of value, can be faked. According to Hawley (2011), know-how is harder to fake than knowledge-that, given that merely apparent propositional knowledge is in general more resilient to our attempts at successful detection than are corresponding attempts to fake know-how. While Hawley’s reasoning for a kind of detection resilience asymmetry between know-how and know-that looks initially plausible, it should ultimately be resisted. In showing why, we outline different ways in which know-how can be faked even when (...) a given performance is successful; and in doing so, we distinguish how know-how can be faked (no less than know-that) via upstream and downstream indicators of its presence, and within each of these categories, we’ll distinguish (in connection with detection resilience) both faking symptoms and (various kinds of) criteria. The unappreciated resilience of faked knowledge-how to successful detection highlights a largely overlooked dimension of social-epistemic risk – risk we face not just in our capacity as recipients of testimony, but in our capacity as both (would-be) apprentices and clients of knowledge-how.

Jury theorems are mathematical theorems about the ability of collectives to make correct decisions. Several jury theorems carry the optimistic message that, in suitable circumstances, ‘crowds are wise’: many individuals together (using, for instance, majority voting) tend to make good decisions, outperforming fewer or just one individual. Jury theorems form the technical core of epistemic arguments for democracy, and provide probabilistic tools for reasoning about the epistemic quality of collective decisions. The popularity of jury theorems spans across various disciplines such (...) as economics, political science, philosophy, and computer science. This entry reviews and critically assesses a variety of jury theorems. It first discusses Condorcet's initial jury theorem, and then progressively introduces jury theorems with more appropriate premises and conclusions. It explains the philosophical foundations, and relates jury theorems to diversity, deliberation, shared evidence, shared perspectives, and other phenomena. It finally connects jury theorems to their historical background and to democratic theory, social epistemology, and social choice theory. (shrink)

What are words? What makes two token words tokens of the same word-type? Are words abstract entities, or are they (merely) collections of tokens? The ontology of words tries to provide answers to these, and related questions. This article provides an overview of some of the most prominent views proposed in the literature, with a particular focus on the debate between type-realist, nominalist, and eliminativist ontologies of words.

Abstract: Might knowledge normatively govern conversations and not just their discrete constituent thoughts and (assertoric) actions? I answer yes, at least for a restricted class of conversations I call aimed conversations. On the view defended here, aimed conversations are governed by participatory know-how - viz., knowledge how to do what each interlocutor to the conversation shares a participatory intention to do by means of that conversation. In the specific case of conversations that are in the service of joint inquiry, the (...) view defended is that interlocutors (A, B, ... n) must intentionally inquire together into whether p, by means of an aimed conversation X, only if A,B, ... n know how to use X to find out together whether p. The view is supported by considerations about instrumental rationality, shared intentionality, the epistemology of intentional action, as well as linguistic data. (shrink)

Political science is divided between methodological individualists, who seek to explain political phenomena by reference to individuals and their interactions, and holists (or nonreductionists), who consider some higher-level social entities or properties such as states, institutions, or cultures ontologically or causally significant. We propose a reconciliation between these two perspectives, building on related work in philosophy. After laying out a taxonomy of different variants of each view, we observe that (i) although political phenomena result from underlying individual attitudes and behavior, (...) individual-level descriptions do not always capture all explanatorily salient properties, and (ii) nonreductionistic explanations are mandated when social regularities are robust to changes in their individual-level realization. We characterize the dividing line between phenomena requiring nonreductionistic explanation and phenomena permitting individualistic explanation and give examples from the study of ethnic conflicts, social-network theory, and international-relations theory.

In the face of conflict, power can be defined as ‘the ability to get one’s needs met [1].’ Power requires not just an ability to do or act by strength and force, but also requires an inherent want and need for a commodity. Yet it is self-explanatory that a desire for power isn’t temporary, but perpetual, with those whose needs are satisfied always yearning for more. This can lead to longer term conflict, suggesting the gradient of power enrooted within society, (...) is the sole perpetrator towards worldwide violence; yet is it possible to completely eradicate violence from society, when individuals, parties and states will never stop their crave for greater power?

Jack Spencer argues we should reject a decision rule called MaxRat because it's incompatible with this principle: If you know that you will choose an option, x, and you know that x is better than every other option available to you, then it is permissible for you to choose x. I agree with Spencer that defenders of MaxRat should reject this principle. However, I disagree insofar as he suggests that he and orthodox causalists are in a position to accept it. (...) Both orthodox CDT and Spencer's own theory of rational choice are incompatible with the principle as well. It is surprising to realise, but all are agreed: it can be irrational to knowingly choose the best. (shrink)

Our aim is to provide a topography of the relevant philosophical terrain with regard to the possible ways in which knowledge can be conceived of as extended. We begin by charting the different types of internalist and externalist proposals within epistemology, and we critically examine the different formulations of the epistemic internalism/externalism debate they lead to. Next, we turn to the internalism/externalism distinction within philosophy of mind and cognitive science. In light of the above dividing lines, we then examine first (...) the extent to which content externalism is compatible with epistemic externalism; second, whether active externalism entails epistemic externalism; and third whether there are varieties of epistemic externalism that are better suited to accommodate active externalism. Finally, we examine whether the combination of epistemic and cognitive externalism is necessary for epistemology and we comment on the potential ramifications of this move for social epistemology and philosophy of science.

Understanding consciousness and its place in the natural world is one of the principal targets of contemporary philosophy of mind. Australian philosophers made seminal contributions to this project during the twentieth century which continue to shape the way philosophers and scientists think about the conceptual, metaphysical and empirical aspects of the problem. After some scene setting, I will discuss the main players and their work in the context of broader developments in the philosophy of mind.

The proposition that digital innovations can put people in charge of their health has been accompanied by prolific talk of empowerment. In this paper we consider ethical challenges and opportunities of trying to achieve justice and empowerment using digital health initiatives. The language of empowerment can misleadingly suggest that by using technology, people can control their health and take responsibility for health outcomes to a greater degree than is realistic or fair. Also, digital health empowerment often primarily reaches people who (...) already have high technological and health literacy, leaving others behind. We critically investigate whether the concept of health empowerment could be re-engineered to mean something different, namely the process of improving the health literacy and access of those who least possess it, in line with recent proposals for conceptual engineering in the service of justice. We settle on the weaker conclusion that underlying ethical values including justice should be used to interpret the existing concept of empowerment. To conclude, we take a high-level view of various strategies for achieving the ethical value associated with digital health empowerment. (shrink)

Die von Kai Pege vorgelegte Theorie beschäftigt sich mit sprachlichen Bezügen. Das Wort ‚selektiv‘ wird in diesem Kontext genutzt, weil die Herangehensweise deskriptiv ist, nicht normativ, weil berücksichtigt wird, dass Bezüge auf Wirklichkeiten einzuschätzen sind, nicht einfach gegeben sind. Selektiv vorzugehen, ist ohnehin Forschungspraxis, nicht einmal an der Bildung eines verbindlichen Ideals hat der Autor ein bekundetes Interesse. -/- Gleichwohl entwickelt Kai Pege im Kontext seiner Analysen ein sprachliches Verfahren, das in besonderer Weise nach Angemessenheit fragt, nach der Angemessenheit von (...) sprachlichen Bedeutungen und möglichen Bezügen. Er spricht von einem ‚analytisch differentiellen‘ Vorgehen, das sogar sprachliche Synonomie verwirft, zu Gunsten von sprachlichen Unterschieden, und zwar zur Erlangung von Bezugsrelevanz und möglichen Bezügen. Ein nicht geringes Gewicht hat in dem Essay die Auseinandersetzung mit relevanten Positionen von Tarski, Quine, Davidson, Kripke, Putnam. (shrink)

The philosophical significance of attitudinal autonomy—viz., the autonomy of attitudes such as beliefs—is widely discussed in the literature on moral responsibility and free will. Within this literature, a key debate centres around the following question: is the kind of attitudinal autonomy that’s relevant to moral responsibility at a given time determined entirely by a subject’s present mental structure at that time? Internalists say ‘yes’, externalists say ’no’. In this essay, I motivate a kind of distinctly epistemic attitudinal autonomy, attitudinal autonomy (...) that is relevant to knowledge. I argue that regardless of whether we are externalists or internalists about the kind of attitudinal autonomy that is relevant for moral responsibility, we should be externalists about the kind of autonomy that a belief must have to qualify as knowledge.

Epistemic relativists often appeal to an epistemic incommensurability thesis. One notable example is the position advanced by Wittgenstein in On certainty (1969). However, Ian Hacking’s radical denial of the possibility of objective epistemic reasons for belief poses, we suggest, an even more forceful challenge to mainstream meta-epistemology. Our central objective will be to develop a novel strategy for defusing Hacking’s line of argument. Specifically, we show that the epistemic incommensurability thesis can be resisted even if we grant the very insights (...) that lead Hacking to claim that epistemic reasons are always relative to a style of reasoning. Surprisingly, the key to defusing the argument is to be found in recent mainstream work on the epistemic state of objectual understanding. (shrink)

n seinem analytischen Essay bearbeitet Pege ein unlängst überfälliges Thema. In der Forschung sind die Sprachphilosophien von Horkheimer und Adorno, sieht man von einigen völlig unzureichenden Absätzen in Büchern und von einigen Aufsätzen ab, unberücksichtigt geblieben. Doch ist Sprachphilosophie auch für die beiden Autoren Grundlage ihres Arbeitens. Nicht minder relevant für die Ausbildungen ihrer Philosophien sind Einflüsse aus jüdischer Theologie. Obwohl es Hinweise genug gibt, hat bislang niemand eine vergleichende Erörterung vorgelegt. Gleichgültig, ob man aus systematischem oder historischem Interesse wissen (...) möchte, was die beiden Autoren in Bezug auf philosophische Sprachen beizutragen haben, die Sprachauffassungen und die Verhältnisse zur jüdischen Theologie müssen sorgfältig geklärt werden. Pege gibt nicht nur eine erste, sondern auch eine ausführliche Diskussion und eine plausible vergleichende Lesart. Er stellt die Philosophien als modernen Messianismus heraus. (shrink)

Information can be public among a group. Whether or not information is public matters, for example, for accounts of interdependent rational choice, of communication, and of joint intention. A standard analysis of public information identifies it with (some variant of) common belief. The latter notion is stipulatively defined as an infinite conjunction: for p to be commonly believed is for it to believed by all members of a group, for all members to believe that all members believe it, and so (...) forth. This analysis is often presupposed without much argument in philosophy. Theoretical entrenchment or intuitions about cases might give some traction on the question, but give little insight about why the identification holds, if it does. The strategy of this paper is to characterize a practical-normative role for information being public, and show that the only things that play that role are (variants of) common belief as stipulatively characterized. In more detail: a functional role for “taking a proposition for granted” in non-isolated decision making is characterized. I then present some minimal conditions under which such an attitude is correctly held. The key assumption links this attitude to beliefs about what is public. From minimal a priori principles, we can argue that a proposition being public among a group entails common commitment to believe among that group. Later sections explore partial converses to this result, the factivity of publicity and publicity from the perspective of outsiders to the group, and objections to the aprioricity of the result deriving from a posteriori existential presuppositions.
