hroughout medieval Christianity, religious works of art emerged to illustrate the teachings of the Bible for the largely illiterate population. What, then, is the significance of the psychoactive mushrooms hiding in plain sight in the artwork and icons of many European and Middle-Eastern churches? Does Christianity have a psychedelic history? -/- Providing stunning visual evidence from their anthropological journey throughout Europe and the Middle East, including visits to Roslyn Chapel and Chartres Cathedral, authors Julie and Jerry Brown document the (...) role of visionary plants in Christianity. They retrace the pioneering research of R. Gordon Wasson, the famous “sacred mushroom seeker,” on psychedelics in ancient Greece and India, and among the present-day reindeer herders of Siberia and the Mazatecs of Mexico. Challenging Wasson’s legacy, the authors reveal his secret relationship with the Vatican that led to Wasson’s refusal to pursue his hallucinogen theory into the hallowed halls of Christianity. -/- Examining the Bible and the Gnostic Gospels, the authors provide scriptural support to show that sacred mushrooms were the inspiration for Jesus’ revelation of the Kingdom of Heaven and that he was initiated into these mystical practices in Egypt during the Missing Years. They contend that the Trees of Knowledge and of Immortality in Eden were sacred mushrooms. -/- Uncovering the role played by visionary plants in the origins of Judeo-Christianity, the authors invite us to rethink what we know about the life of Jesus and to consider a controversial theory that challenges us to explore these sacred pathways to the divine.

This chapter describes the potential far‐reaching consequences of contemplative higher education for the fields of science and medicine.

Abstract: It is the aim of this paper to establish a temporal and cultural link between entheogen-use1 in Classical mystery cults and their possible use in a segment of the early Christian Gnostic Church. As early Christianity was heavily influenced by the Classical world in which it first developed, it is essential to examine the evidence of entheogen-use within Classical mystery cults, and explore their possible influence on the development of Christian ritual. We will first present textual evidence from the (...) New Testament and Nag Hammadi Library (NHL) that indicate possible use of ritual entheogens. Next we will examine entheogen-use by some of the main religious sects of the ancient Mediterranean world as part of their liturgical practice between c. fifth century BCE and the third century CE. Then we will show that the different schools of philosophical thought examined were quite fluid, and that there was considerable overlap among schools with respect to several key philosophies and practices. Ultimately the subject of entheogen-use in the Classical world necessarily falls into the realm of plausible speculation mainly due to the lack of primary sources. However, should the entheogenic hypothesis2 prove to be correct, it promises to be quite useful in future research and in the translation of original documents. (shrink)

Functional diversity holds the promise of understanding ecosystems in ways unattainable by taxonomic diversity studies. Underlying this promise is the intuition that investigating the diversity of what organisms actually do—i.e. their functional traits—within ecosystems will generate more reliable insights into the ways these ecosystems behave, compared to considering only species diversity. But this promise also rests on several conceptual and methodological—i.e. epistemic—assumptions that cut across various theories and domains of ecology. These assumptions should be clearly addressed, notably for the sake (...) of an effective comparison and integration across domains, and for assessing whether or not to use functional diversity approaches for developing ecological management strategies. The objective of this contribution is to identify and critically analyze the most salient of these assumptions. To this aim, we provide an “epistemic roadmap” that pinpoints these assumptions along a set of historical, conceptual, empirical, theoretical, and normative dimensions. (shrink)

According to QBism, quantum states, unitary evolutions, and measurement operators are all understood as personal judgments of the agent using the formalism. Meanwhile, quantum measurement outcomes are understood as the personal experiences of the same agent. Wigner’s conundrum of the friend, in which two agents ostensibly have different accounts of whether or not there is a measurement outcome, thus poses no paradox for QBism. Indeed the resolution of Wigner’s original thought experiment was central to the development of QBist thinking. The (...) focus of this paper concerns two very instructive modifications to Wigner’s puzzle: One, a recent no-go theorem by Frauchiger and Renner, and the other a thought experiment by Baumann and Brukner. We show that the paradoxical features emphasized in these works disappear once both friend and Wigner are understood as agents on an equal footing with regard to their individual uses of quantum theory. Wigner’s action on his friend then becomes, from the friend’s perspective, an action the friend takes on Wigner. Our analysis rests on a kind of quantum Copernican principle: When two agents take actions on each other, each agent has a dual role as a physical system for the other agent. No user of quantum theory is more privileged than any other. In contrast to the sentiment of Wigner’s original paper, neither agent should be considered as in “suspended animation.” In this light, QBism brings an entirely new perspective to understanding Wigner’s friend thought experiments.

Public health care interventions—regarding vaccination, obesity, and HIV, for example—standardly take the form of information dissemination across a community. But information networks can vary importantly between different ethnic communities, as can levels of trust in information from different sources. We use data from the Greater Pittsburgh Random Household Health Survey to construct models of information networks for White and Black communities--models which reflect the degree of information contact between individuals, with degrees of trust in information from various sources correlated with (...) positions in that social network. With simple assumptions regarding belief change and social reinforcement, we use those modeled networks to build dynamic agent-based models of how information can be expected to flow and how beliefs can be expected to change across each community. With contrasting information from governmental and religious sources, the results show importantly different dynamic patterns of belief polarization within the two communities. (shrink)

The appearance of negative terms in quasiprobability representations of quantum theory is known to be inevitable, and, due to its equivalence with the onset of contextuality, of central interest in quantum computation and information. Until recently, however, nothing has been known about how much negativity is necessary in a quasiprobability representation. Zhu :120404, 2016) proved that the upper and lower bounds with respect to one type of negativity measure are saturated by quasiprobability representations which are in one-to-one correspondence with the (...) elusive symmetric informationally complete quantum measurements. We define a family of negativity measures which includes Zhu’s as a special case and consider another member of the family which we call “sum negativity.” We prove a sufficient condition for local maxima in sum negativity and find exact global maxima in dimensions 3 and 4. Notably, we find that Zhu’s result on the SICs does not generally extend to sum negativity, although the analogous result does hold in dimension 4. Finally, the Hoggar lines in dimension 8 make an appearance in a conjecture on sum negativity. (shrink)

Clarke and Beck assume that approximate number system representations should be assigned referents from our scientific ontology. However, many representations, both in perception and cognition, do not straightforwardly refer to such entities. If we reject Clarke and Beck's assumption, many possible contents for ANS representations besides number are compatible with the evidence Clarke and Beck cite.

This World Bank Report offers a new conception of fair decision processes in health financing. It argues that such procedural fairness can contribute to fairer outcomes, strengthen the legitimacy of decision processes, build trust in authorities, and promote the sustainability of reforms on the path to health coverage for all.

Machine learning algorithms may radically improve our ability to diagnose and treat disease. For moral, legal, and scientific reasons, it is essential that doctors and patients be able to understand and explain the predictions of these models. Scalable, customisable, and ethical solutions can be achieved by working together with relevant stakeholders, including patients, data scientists, and policy makers.

I. EXECUTIVE SUMMARY The MRCT Center Post-trial Responsibilities: Continued Access to an Investigational Medicine Framework outlines a case-based, principled, stakeholder approach to evaluate and guide ethical responsibilities to provide continued access to an investigational medicine at the conclusion of a patient’s participation in a clinical trial. The Post-trial Responsibilities (PTR) Framework includes this Guidance Document as well as the accompanying Toolkit. A 41-member international multi-stakeholder Workgroup convened by the Multi-Regional Clinical Trials Center of Brigham and Women’s Hospital and Harvard University (...) (MRCT Center) developed this Guidance and Toolkit. Project Motivation A number of international organizations have discussed the responsibilities stakeholders have to provide continued access to investigational medicines. The World Medical Association, for example, addressed post-trial access to medicines in Paragraph 34 of the Declaration of Helsinki (WMA, 2013): “In advance of a clinical trial, sponsors, researchers and host country governments should make provisions for post-trial access for all participants who still need an intervention identified as beneficial in the trial. This information must also be disclosed to participants during the informed consent process.” This paragraph and other international guidance documents converge on several consensus points: • Post-trial access (hereafter referred to as “continued access” in this Framework [for terminology clarification – see definitions]) is the responsibility of sponsors, researchers, and host country governments; • The plan for continued access should be determined before the trial begins, and before any individual gives their informed consent; • The protocol should delineate continued access plans; and • The plan should be transparent to potential participants and explained during the informed consent process. -/- However, there is no guidance on how to fulfill these responsibilities (i.e., linking specific responsibilities with specific stakeholders, conditions, and duration). To fill this gap, the MRCT Center convened a working group in September of 2014 to develop a framework to guide stakeholders with identified responsibilities. This resultant Framework sets forth applicable principles, approaches, recommendations and ethical rationales for PTR regarding continued access to investigational medicines for research participants.

The paper argues that an account of understanding should take the form of a Carnapian explication and acknowledge that understanding comes in degrees. An explication of objectual understanding is defended, which helps to make sense of the cognitive achievements and goals of science. The explication combines a necessary condition with three evaluative dimensions: an epistemic agent understands a subject matter by means of a theory only if the agent commits herself sufficiently to the theory of the subject matter, and to (...) the degree that the agent grasps the theory (i.e., is able to make use of it), the theory answers to the facts and the agent’s commitment to the theory is justified. The threshold for outright attributions of understanding is determined contextually. The explication has descriptive as well as normative facets and allows for the possibility of understanding by means of non-explanatory (e.g., purely classificatory) theories. (shrink)

This commentary defends 3 arguments for changing the label of levonorgestrel-based emergency contraception (LNG EC) so that it no longer supports the possibility of a mechanism of action after fertilization. First, there is no direct scientific evidence confirming any postfertilization mechanisms. Second, despite the weight of evidence, there is still widespread public misunderstanding over the mechanism of LNG EC. Third, this FDA label is not a value-free claim, but instead it has functioned like a political tool for reducing contraceptive access. (...) The label is laden with antiabortion values (even though EC is contraception, not abortion), and it imposes these values on potential users, resulting in barriers to access such as with Burwell v. Hobby Lobby. These 3 arguments together provide scientific, social, and ethical grounds for the FDA to take the initiate in changing Plan B's drug label. (shrink)

Christopher Hookway has been influential in promoting engagement with pragmatist and naturalist perspectives from classical and contemporary American philosophy. This book reflects on Hookway’s work on the American philosophical tradition and its significance for contemporary discussions of the understanding of mind, meaning, knowledge, and value. -/- Hookway’s original and extensive studies of Charles S. Peirce have made him among the most admired and frequently referenced of Peirce’s interpreters. His work on classical American pragmatism has explored the philosophies of William (...) James, John Dewey, and Josiah Royce, and examined the influence of pragmatist ideas outside of the United States. Additionally, Hookway has participated in a number of celebrated exchanges with some of the most high-profile figures of twentieth- and twenty-first-century philosophy, including Karl-Otto Apel, Philip Pettit, Hilary Putnam, and W.V.O. Quine, through which his treatments of a large range of topics in epistemology and the philosophies of mind and language have been developed and promoted. The chapters in this book—which include contributions from several of Hookway’s former students and colleagues—include studies of Hookway’s engagement with the works of Peirce, James, and Dewey, his contributions to virtue epistemology, and his discussions of hope and pragmatist metaphysics. -/- Pragmatic Reason will be of interest to researchers and advanced students working on American philosophy, the history of analytic philosophy, and epistemology.

This paper asks whether a necessity can be the source of necessity. According to an influential argument due to Simon Blackburn, it cannot. This paper argues that although Blackburn fails to show that a necessity cannot be the source of necessity, extant accounts fail to establish that it is, with particular focus on Bob Hale’s essentialist theory and Christopher Peacocke’s ‘principle-based’ theory of modality. However, the paper makes some positive suggestions for what a satisfactory answer to the challenge must (...) look like. (shrink)

Das spezifische Ziel von Argumentationen ist nicht einfach, den Adressaten etwas glauben zu machen - dies wäre bloße Rhetorik ﷓, sondern: den Adressaten beim Erkennen der Akzeptabilität (insbesondere der Wahrheit) der These anzuleiten und ihn so zu begründetem Glauben, zu Erkenntnis zu führen. Argumentationen leiten das Erkennen an, indem sie in ihren Argumenten hinreichende Akzeptabilitätsbedingungen der These als erfüllt beurteilen und so den Adressaten implizit auffordern, diese Bedingungen zu überprüfen. Argumentationen sind gültig, wenn sie prinzipiell das Erkennen anleiten können; d. (...) h. wenn die genannten Akzeptabilitätsbedingungen hinreichend sind, wenn sie tatsächlich erfüllt (die Argumente also wahr) sind und wenn es irgendjemanden gibt, der zwar die Akzeptabilität der Argumente, nicht aber die der These erkannt hat. Eine gültige Argumentation ist adäquat, um einen bestimmten Adressaten rational zu überzeugen, wenn dieser u. a. die Akzeptabilität der Argumente, nicht aber die der These erkannt hat. Die in gültigen Argumentationen als erfüllt beurteilten Akzeptabilitätsbedingungen sind Konkretisierungen allgemeiner Erkenntnisprinzipien für die spezifische These, z. B. des deduktiven Erkenntnisprinzips: 'Eine Proposition ist wahr, wenn sie von wahren Propositionen logisch impliziert wird.' oder des erkenntnisgenetischen Erkenntnisprinzips: 'Eine Proposition ist wahr, wenn sie korrekt verifiziert worden ist.' Eine Konkretisierung des deduktiven Prinzips für eine These p wäre z. B.: 'p ist wahr, 1. wenn q und r wahr sind und 2. wenn q und r zusammen p logisch implizieren.' Sind beide Bedingungen erfüllt, so könnte 'q; r; also p.' eine gültige deduktive Argumentation sein. Die verschiedenen Argumentationstypen unterscheiden sich danach, auf welchem Erkenntnisprinzip sie basieren. Das argumentativ angeleitete Erkennen der Akzeptabilität der These funktioniert so: Der Adressat benutzt das von ihm (zumindest implizit) gewußte allgemeine Erkenntnisprinzip als Checkliste, auf der er nach dem Vorbringen der Argumente abhakt, welche Akzeptabilitätsbedingung des Erkenntnisprinzips durch das Zutreffen des Arguments jeweils erfüllt wird. Auf der Basis dieser Funktionsbestimmung werden in der "Praktischen Argumentationstheorie" (erstmalig) präzise Gültigkeitskriterien für Argumentationen allgemein und für mehrere spezielle Argumentationstypen entwickelt, erkenntnistheoretisch begründet und auf komplexe Argumentationsbeispiele aus Philosophie, Wissenschaft, Technik und Kultur angewendet. Die Analyse der erkenntnistheoretischen Grundlagen - der zugrundeliegenden Erkenntnisprinzipien - vor allem der interpretierenden und praktischen Argumentationen ist zudem von erheblicher Bedeutung weit über die Argumentationstheorie hinaus: für die Interpretationstheorie, die Handlungstheorie und die praktische Philosophie.

While the Value-Free Ideal of science has suffered compelling criticism, some advocates like Gregor Betz continue to argue that science policy advisors should avoid value judgments by hedging their hypotheses. This approach depends on a mistaken understanding of the relations between facts and values in regulatory science. My case study involves the morning-after pill Plan B and the “Drug Fact” that it “may” prevent implantation. I analyze the operative values, which I call zygote-centrism, responsible for this hedged drug label. Then, (...) I explain my twofold account of value-ladenness, involving the constitutive role of value judgments in science and the social function of facts as political tools. Because this drug fact is ineliminably value-laden in both senses, I conclude that hedged hypotheses are not necessarily value-free. (shrink)

At the centre of Arthur Prior’s ‘Thank goodness’ argument for the A-theory of time is a particular form of relief. Time must objectively pass, Prior argues, or else the relief felt when a painful experience has ended is not intelligible. In this paper, I offer a detailed analysis of the type of relief at issue in this argument, which I call temporal relief, and distinguish it from another form of relief, which I refer to as counterfactual relief. I also argue (...) that existing discussions of the ‘Thank goodness’ argument—including Prior’s own—fail to give a satisfactory account of temporal relief, and that it needs to be seen as an emotion linked to the ability to engage in fairly sophisticated forms of planning. I also suggest that this has an impact on Prior’s claim that the idea of points in time plays no fundamental role in the semantic analysis of tenses. (shrink)

Adviser: Professor Stefan Baumrin In the first chapter I introduce the distinction between metaethics and normative ethics and argue that metaethics, properly conceived, is a part of cognitive science. For example, the debate between rationalism and sentimentalism can be informed by recent empirical work in psychology and the neurosciences. In the second chapter I argue that the traditional view that one’s theory of semantics determines what one’s theory of justification must be is mistaken. Though it has been the case that (...) there are ‘typical’ combinations of semantic and justificational theories this is by no means forced on one. In the third chapter I examine two current kinds of expressivism; that of Blackburn and Copp. Each gives us an example of different combinations of semantic and justificatory theory. In Blackburn’s case he combines a use theory of meaning with a classic emotivist theory of justification, In Copp’s case it is a neo-Gricean philosophy of language with a realist’s theory of justification. I find both of these wanting as they ultimately collapse into relativistic subjectivism. In the fourth and fifth chapter I turn to developing Emotive Realism. The basic idea behind this view is that when someone says ‘x is wrong/right’ that person has (a) expressed a moral emotion about x and at the same time (b) expressed the belief that the emotion in (a) is the correct one to have. The belief expressed in (b) will be true or false depending on one’s theory of justification. In the fourth chapter I argue that we need separate semantic theories for thoughts and sentences. In the fifth chapter I fill in the details of Emotive Realism as I see it. (shrink)

In (Weaver 2021), I showed that Boltzmann’s H-theorem does not face a significant threat from the reversibility paradox. I argue that my defense of the H-theorem against that paradox can be used yet again for the purposes of resolving the recurrence paradox without having to endorse heavy-duty statistical assumptions outside of the hypothesis of molecular chaos. As in (Weaver 2021), lessons from the history and foundations of physics reveal precisely how such resolution is achieved.

Cognitive abilities cannot be measured directly. What we can measure is individual variation in task performance. In this paper, we first make the case for why we should be interested in mapping individual differences in task performance on to particular cognitive abilities: we suggest that it is crucial for examining the causes and consequences of variation both within and between species. As a case study, we examine whether multiple measures of inhibitory control for non-human animals do indeed produce correlated task (...) performance; however, no clear pattern emerges that would support the notion of a common cognitive ability underpinning individual differences in performance. We advocate a psychometric approach involving a three-step programme to make theoretical and empirical progress: first, we need tasks that reveal signature limits in performance. Second, we need to assess the reliability of individual differences in task performance. Third, multi-trait multi-method test batteries will be instrumental in validating cognitive abilities. Together, these steps will help us to establish what varies between individuals that could impact their fitness and ultimately shape the course of the evolution of animal minds. Finally, we propose executive functions, including working memory, inhibitory control and attentional shifting, as a sensible starting point for this endeavour. (shrink)

The relations between life and cogntion have been addressed through different perspectives [Stewart 1996, Boden 2001, Bourgine and Stewart 2004, van Duijn & all 2006, Di Paolo 2009]. We would like here to address that subject by relating life to cognition through a process of meaning generation. Life emerged on earth as a far from thermodynamic equilibrium performance that had to maintain herself. Life is charactertized by a ‘stay alive’ constraint that has to be satisfied (such constraint can be included (...) in the constraint of being able to maintain far from equilibrium thermodynamic conditions [Bickhard 2011]). The local ‘stay alive‘ constraint has to be satisfied in an environment containing elements potentially supportive or harmfull. A key activity for the living entity is to characterize these elements in terms of meaningfulness relatively to the ‘stay alive’ constraint. This process can be modeled with an existing tool where a system submitted to an internal constraint generates meaningful information characterizing elements of the environment: the Meaning Generator System (MGS) [Menant, 2003, 2014 a]. In a few words: when a system submitted to an internal constraint receives from the environment an information that has a connection with the constraint it generates a meaning usable for the implementation of an action satisfying the constraint.The generated meaning is the connection existing between the received information and the constraint. The MGS models this process and interfaces to the action implementation for constraint satisfaction The meaning is generated by and for the system. The MGS grounds meaning generation in constraint satisfaction and links the living entity to her environment in a relational process. A simple example is with a paramecium close to a drop of acid. The paramecium which is submitted to a ‘stay alive’ constraint will move away from the acid area. The received information ‘presence of acid’ generates the meaning ‘acid not compatible with the ‘stay alive’ constraint‘ which triggers the moving away action (that example is close to Varela’s bacteria swimming up a sugar gradient. What the MGS brings in addition is a modeling of the significance of the chemical gradient for the organism). The action implemented to satisfy the constraint modifies the environment and the received information, establishing an interactive process linking the living entity to her environment. During its evolution animal life has elaborated new constraints (like ‘live group life’) and new functions enriching meaning generation and action scenarios. As a result the build up of meaningful representations has improved the constraint satisfaction processes of animals, embedding them in their environments in relational and interactive terms [Menant, 2011]. Cognition can be defined by proposing that ‘a system is cognitive if and only if sensory inputs serve to trigger actions in a specific way, so as to satisfy a viability constraint’ [Bourgine, Stewart 2004]. Cognition can also be considered as exemplifying a ‘vital criterion of responsiveness’ [Boden, 2001 ]. Consequently the MGS can be positioned as an elementary and generic version of animal cognition. For animal life, meaning generation for internal constraint satisfaction links life and cognition in a relational and interactive process. Cognition for human life is more complex as new performances have to be taken into account like self-consciousness and free-will. Meaning generation at human level is a challenging subject as human constraints are not clearly understood [Menant, 2011]. Many research activities are in process looking for some understanding of human mind [Philpapers]. One area of investigation is an evolutionary approach to self-consciousness using meaning generation where anxiety limitation comes up as a generic human constraint [Menant, 2014 b]. Assuming that we can have clear enough an understanding of some human constraints, we can look at the MGS for partly extending to humans the link between life and cognition that has been established for animals. So overall, we can consider that the MGS approach makes available an evolutionary link between life and cognition for animals, and partly for humans. A characteristic of the proposed system approach to meaning generation is the possibility to use it for any type of agent, be it organic (with intrinsic constraints ) or artificial (with derived constraints). Such characterization of agents through meaning generation can be used to discriminate artificial itelligence from human intelligence (see the MGS usage to support Searle’s chinese room argument [Menant, 2013]). On a more general basis, the proposed system approach can positions the MGS as a simple model for an internal source of normativity. It’s usage as a simple building block allows a bottom-up modeling for normativity in the sensorimotor approach. The ‘stay alive’ constraint could also be taken as a starting point for an evolutionary grounding of sensorimotor norms ‘in the biological normativity of the agent as a whole’ [Di Paolo & all 2014]. The proposed presentation will develop the points summarized here above and position them relatively to the autopoietic and enactive approaches. Several possible continuations will also be highlighted. (shrink)

With regard to recent historical developments, the Social Model has been of enormous emancipatory significance, chiefly as a counter-agent against rigid definitions of dis-/ability and the traditional role (marked by misfortune) imposed on disabled people. Based on underdetermined notions of “social construction”, this model presently threatens to unduly narrow reflections on the existential conditions of disabled agents, and to obscure crucial questions facing just social orders of the future. These notions imply an overemphasis on linguistic/mental and cultural acts in the (...) shaping of life courses, whereas physical, practical and existential pre-conditions of life come to be disregarded as purportedly freely available, (natural) features. Conversely, this argumentation sketch – a contribution to DisKo18 – works towards a reconceptualisation of disability rooted in external realism, assuming partially autonomous agents. The paper asks: What is the place of disabled people in the world, given that the elementary conditions and problems of life are not primarily of human origin, but arise out of a complex interaction with elements of external reality? What space remains to them in view of extant impairment-related restrictions? Based on a critique of constructionist tenets, possibilities for a just social order are discussed, considering (a) disabilities vs. (b) external, pre-social factors that limit the range of possible social solutions, with special regard to available resources. This approach is exemplified by placing disability in contexts of ecological sustainability. (Paper in German, short version). (shrink)

Anxiety is a main contributor to human psychological sufferings. Its evolutionary sources are generally related to alert signals for coping with adverse or unexpected situations [Steiner, 2002] or to hunter-gatherer emotions mismatched with today environments [Horwitz & Wakefield, 2012]. We propose here another evolutionary perspective that links human anxiety to an evolutionary nature of self-consciousness. That approach introduces new relations between mental health and human mind. The proposed evolutionary scenario starts with the performance of primate identification with conspecifics [de Waal (...) 1998, 2008]. It is assumed that the evolution of that identification brought our ancestors to represent themselves as entities existing in the environment, like conspecifics were represented as existing in the environment. We consider that this process has implemented in the mind of our ancestors some first elements of self-consciousness [Menant 2014a]. But the same process has also produced new sufferings coming from identification with suffering or endangered conspecifics. In addition, the emerging performance of self-focus brought in the new feeling of being a suffering entity. We consider that all these new sufferings have created in the mind of our primate ancestors a huge anxiety increase, unbearable if not limited. Among the options available to limit that anxiety increase we focus on two of them that may have taken place. The first was a withdrawal from the process. Some primates may have simply rejected the evolution of identification (and with it self-consciousness). This may have led them to an ecological niche resulting in our today great apes. The second option was about limiting the causes of sufferings and taking advantage of possible resulting evolutionary benefits. This may have been achieved by developing performances like imitation, communication, simulation, synergy and ToM. Added to a positive feedback on identification these performances may have initiated an evolutionary engine that has accelerated the evolution toward human self-consciousness. That option is characterized by an early build up of anxiety limitation processes in an evolutionary nature of our human self-consciousness. This option corresponds to a human specificity and introduces anxiety management and self-consciousness as sharing a same evolutionary story. The build up of these anxiety management processes is now buried in the evolutiony story of our human mind. But these processes are still present in our minds at an unconscious level and participate to many of our human mental states and behaviors. Such positioning of anxiety management as part of the nature of human mind is new and makes available entry points for new understandings of human emotion, motivations and mental disorders. The proposed evolutionary scenario has been introduced in philosophy of mind [Menant 2011, 2014a, b] but it has not been so far explicitly part of primatology nor of psychology/psychiatry/ethics. We present here a drawing of the scenario with highlights on corresponding key points. More work is needed on these new evolutionary links between human mind and anxiety management.

In this article I examine two mathematical definitions of observational equivalence, one proposed by Charlotte Werndl and based on manifest isomorphism, and the other based on Ornstein and Weiss’s ε-congruence. I argue, for two related reasons, that neither can function as a purely mathematical definition of observational equivalence. First, each definition permits of counterexamples; second, overcoming these counterexamples will introduce non-mathematical premises about the systems in question. Accordingly, the prospects for a broadly applicable and purely mathematical definition of observational equivalence (...) are unpromising. Despite this critique, I suggest that Werndl’s proposals are valuable because they clarify the distinction between provable and unprovable elements in arguments for observational equivalence.

In order to understand the transmission of a disease across a population we will have to understand not only the dynamics of contact infection but the transfer of health-care beliefs and resulting health-care behaviors across that population. This paper is a first step in that direction, focusing on the contrasting role of linkage or isolation between sub-networks in (a) contact infection and (b) belief transfer. Using both analytical tools and agent-based simulations we show that it is the structure of a (...) network that is primary for predicting contact infection—whether the networks or sub-networks at issue are distributed ring networks or total networks (hubs, wheels, small world, random, or scale-free for example). Measured in terms of time to total infection, degree of linkage between sub-networks plays a minor role. The case of belief is importantly different. Using a simplified model of belief reinforcement, and measuring belief transfer in terms of time to community consensus, we show that degree of linkage between sub-networks plays a major role in social communication of beliefs. Here, in contrast to the case of contract infection, network type turns out to be of relatively minor importance. What you believe travels differently. In a final section we show that the pattern of belief transfer exhibits a classic power law regardless of the type of network involved. (shrink)

A recent focus on philosophical methodology has reinvigorated ordinary language philosophy with the contention that philosophical inquiry is better served by attending to the ordinary use of language. Taking cues from findings in the social sciences that deploy methods utilizing language, various ordinary language philosophers embrace a guiding mandate: that ordinary language usage is more reflective of our linguistic and conceptual competencies than standard philosophical methods. We analyze two hypotheses that are implicit in the research from which ordinary language approaches (...) take their cues. This pair of optimistic assumptions (a) bind word meanings to properties of their corresponding concepts and (b) regard language as a direct reflection of our underlying cognitive processes and competencies. Polysemy and pragmatics complicate each assumption. Because the ordinary language philosopher’s methodological mandate compels us to consider how individuals process the utterances they encounter in deciphering the communicative intentions of speakers, failing to attend to the import of polysemy and pragmatics in philosophical and empirical methods has the potential to frustrate the aims of their insightful mandate. The significance of those two complications is worked out with the case study of knowledge. (shrink)

One of the mains challenges of biosemiotics is ‘to attempt to naturalize biological meaning’ [Sharov & all 2015]. That challenge brings to look at a possible evolutionary thread for biosemiotics based on meaning generation for internal constraint satisfaction, starting with a pre-biotic entity emerging from a material universe. Such perspective complements and extends previous works that used a model of meaning generation for internal constraint satisfaction (the Meaning Generator System) [Menant 2003a, b; 2011]. We propose to look at such an (...) evolutionary thread for biosemiotics in three steps. The first step presents the proposed emergence of a pre-biotic entity as a far from thermodynamic equilibrium volume constrained to maintains its status [Menant 2015]. Such constraint dependence introduces natural links with teleology and with meaning generation. It also introduces perspectives for evolutionary origins of agency, self, and autonomy, coming in addition to other biosemiotic perspectives [Tønnessen, 2015]. The next step recalls the MGS as being a system approach linking the agent containing it to its environment and bringing to the agent a control from within. We apply the MGS to animal life. Relations with the Umwelt, with constructivism and with the Peircean triadic approach are highlighted. The last step of the thread brings the evolution of life up to humans where specificities related to human mind have to be taken into account. Among them is self-consciousness for which an existing evolutionary scenario introduces anxiety management as a foundational human constraint [Menant, 2014]. We link that scenario to the evolutionary thread because it introduces specific human constraints and is based on the evolution of meaningful representations. A conclusion summarizes the steps of the proposed evolutionary thread. More work is needed on that subject. Possible continuations are introduced. (shrink)

In the Bayesian approach to quantum mechanics, probabilities—and thus quantum states—represent an agent’s degrees of belief, rather than corresponding to objective properties of physical systems. In this paper we investigate the concept of certainty in quantum mechanics. Particularly, we show how the probability-1 predictions derived from pure quantum states highlight a fundamental difference between our Bayesian approach, on the one hand, and Copenhagen and similar interpretations on the other. We first review the main arguments for the general claim that probabilities (...) always represent degrees of belief. We then argue that a quantum state prepared by some physical device always depends on an agent’s prior beliefs, implying that the probability-1 predictions derived from that state also depend on the agent’s prior beliefs. Quantum certainty is therefore always some agent’s certainty. Conversely, if facts about an experimental setup could imply agent-independent certainty for a measurement outcome, as in many Copenhagen-like interpretations, that outcome would effectively correspond to a preexisting system property. The idea that measurement outcomes occurring with certainty correspond to preexisting system properties is, however, in conflict with locality. We emphasize this by giving a version of an argument of Stairs [(1983). Quantum logic, realism, and value-definiteness. Philosophy of Science, 50, 578], which applies the Kochen–Specker theorem to an entangled bipartite system. (shrink)

In The Realm of Reason (2004), Christopher Peacocke develops a “generalized rationalism” concerning, among other things, what it is for someone to be “entitled”, or justified, in forming a given belief. In the course of his discussion, Peacocke offers two arguments to the best explanation that aim to undermine scepticism and establish a justification for our belief in the reliability of sense perception, respectively. If sound, these ambitious arguments would answer some of the oldest and most vexing epistemological problems. (...) In this paper I will evaluate these arguments, concluding that they are inconclusive at best. Despite offering some interestingly original arguments, Peacocke gives us no reason to think that scepticism is false, and that perception is generally reliable. (shrink)

Philosophical debates about the metaphysics of time typically revolve around two contrasting views of time. On the A-theory, time is something that itself undergoes change, as captured by the idea of the passage of time; on the B-theory, all there is to time is events standing in before/after or simultaneity relations to each other, and these temporal relations are unchanging. Philosophers typically regard the A-theory as being supported by our experience of time, and they take it that the B-theory clashes (...) with how we experience time and therefore faces the burden of having to explain away that clash. In this paper, we investigate empirically whether these intuitions about the experience of time are shared by the general public. We asked directly for people’s subjective reports of their experience of time—in particular, whether they believe themselves to have a phenomenology as of time’s passing—and we probed their understanding of what time’s passage in fact is. We find that a majority of participants do share the aforementioned intuitions, but interestingly a minority do not. (shrink)

In this paper, new evidence is presented for the assumption that the reason-relation reading of indicative conditionals ('if A, then C') reflects a conventional implicature. In four experiments, it is investigated whether relevance effects found for the probability assessment of indicative conditionals (Skovgaard-Olsen, Singmann, and Klauer, 2016a) can be classified as being produced by a) a conversational implicature, b) a (probabilistic) presupposition failure, or c) a conventional implicature. After considering several alternative hypotheses and the accumulating evidence from other studies as (...) well, we conclude that the evidence is most consistent with the Relevance Effect being the outcome of a conventional implicature. This finding indicates that the reason-relation reading is part of the semantic content of indicative conditionals, albeit not part of their primary truth-conditional content. (shrink)

In Tulving’s initial characterization, episodic memory was one of multiple memory systems. It was postulated, in pursuit of explanatory depth, as displaying proprietary operations, representations, and substrates such as to explain a range of cognitive, behavioural, and experiential phenomena. Yet the subsequent development of this research program has, paradoxically, introduced surprising doubts about the nature, and indeed existence, of episodic memory. On dominant versions of the ‘common system’ view, on which a single simulation system underlies both remembering and imagining, there (...) are no processes unique to memory to support robust generalizations with inductive potential. Eliminativism about episodic memory seems to follow from the claim that it has no dedicated neurocognitive system of its own. After identifying this under-noticed threat, we push back against modern eliminativists by surveying recent evidence that still indicates specialized mechanisms, computations, and representations that are distinctly mnemic in character. We argue that contemporary realists about episodic memory can retain lessons of the common system approach while resisting the further move to eliminativism. (shrink)

John Rawls’s political liberalism and its ideal of public reason are tremendously influential in contemporary political philosophy and in constitutional law as well. Many, perhaps even most, liberals are Rawlsians of one stripe or another. This is problematic, because most liberals also support the redefinition of civil marriage to include same-sex unions, and as I show, Rawls’s political liberalism actually prohibits same- sex marriage. Recently in Perry v. Schwarzenegger, however, California’s northern federal district court reinterpreted the traditional rational basis review (...) in terms of liberal neutrality akin to Rawls’s “public reason,” and overturned Proposition 8 and established same-sex marriage. (This reinterpretation was amplified in the 9th Circuit Court’s decision upholding the district court on appeal in Perry v. Brown.) But on its own grounds Perry should have drawn the opposite conclusion. This is because all the available arguments for recognizing same-sex unions as civil marriages stem from controversial comprehensive doctrines about the good, and this violates the ideal of public reason; yet there remains a publicly reasonable argument for traditional marriage, which I sketch here. In the course of my argument I develop Rawls’s politically liberal account of the family by drawing upon work by J. David Velleman and H. L. A. Hart, and discuss the implications of this account for political theory and constitutional law. (shrink)

The theme of the conflict between the different interpretations of Spinoza’s philosophy in French scholarship, introduced by Christopher Norris in this volume and expanded on by Alain Badiou, is also central to the argument presented in this chapter. Indeed, this chapter will be preoccupied with distinguishing the interpretations of Spinoza by two of the figures introduced by Badiou. The interpretation of Spinoza offered by Gilles Deleuze in Expressionism in Philosophy provides an account of the dynamic changes or transformations of (...) the characteristic relations of a Spinozist finite existing mode, or human being. This account has been criticized more or less explicitly by a number of commentators, including Charles Ramond. Rather than providing a defence of Deleuze on this specific point, which I have done elsewhere, what I propose to do in this chapter is provide an account of the role played by “joyful passive a affections” in these dynamic changes or transformations by distinguishing Deleuze’s account of this role from that offered by one of his more explicit critics on this issue, Pierre Macherey. An appreciation of the role played by “joyful passive affections” in this context is crucial to understanding how Deleuze’s interpretation of Spinoza is implicated in his broader philosophical project of constructing a philosophy of difference. The outcome is a position that, like Badiou in the previous chapter, rules out “intellect in potentiality” but maintains a role for the joyful passive affects in the development of adequate ideas.

In “What’s So Bad about Scientism?” (Mizrahi 2017), I argue that Weak Scientism, the view that “Of all the knowledge we have, scientific knowledge is the best knowledge” (Mizrahi 2017, 354; emphasis in original) is a defensible position. That is to say, Weak Scientism “can be successfully defended against objections” (Mizrahi 2017, 354). In his response to Mizrahi (2017), Christopher Brown (2017) provides more objections against Weak Scientism, and thus another opportunity for me to show that Weak Scientism (...) is a defensible position, which is what I will do in this reply. In fact, I think that I have already addressed Brown’s (2017) objections in Mizrahi (2017), so I will simply highlight these arguments here. (shrink)

§1.1 What m otivated the perpetrators of the holocaust? Christopher Browning and Daniel Goldhagen differ in their analysis of Reserve Police Battalion 101 (Browning 1992, Goldhagen 1996).

An underexamined insight of W. E. B. Du Bois’s John Brown is that John Brown worked for much of his life to cultivate democratic relationships with the Black Americans with and for whom he worked. Brown did so through practicing deference and deliberation, and by seeking authorization. However, Brown’s commitment to these practices faltered at a crucial moment in decision making: when he raided Harpers Ferry absent widespread support. Examining this aspect of John Brown brings (...) into relief an overlooked tragic choice Brown made: To act in accordance with his own substantive vision of what justice required, Brown eschewed democratic ideals and practices that grounded the distinctive relations of equality he had cultivated with the Black communities with and for whom he worked.

Bernard Wills (2018) joins Christopher Brown (2017, 2018) in criticizing my defense of Weak Scientism (Mizrahi 2017a, 2017b, 2018a). Unfortunately, it seems that Wills did not read my latest defense of Weak Scientism carefully, nor does he cite any of the other papers in my exchange with Brown.

Report submitted by Gregory B. Sadler, Pilot Project Coordinator to Sonya Brown, WAC Activity Director, Fayetteville State University, June 28 2011. -/- A Pilot program focused on improving student performance in carrying out Close Readings in humanities-based discipline courses was developed and implemented under the auspices of Writing Across the Curriculum and Title III at Fayetteville State University in Winter and Spring 2011. Five faculty were involved in the Pilot, myself as the coordinator, and four other faculty from four (...) different disciplines as participants. -/- The central idea behind the Pilot was that by focusing on the lower-order skills which are scaffolded as components into the higher-order activity of Close Reading of texts, and redesigning courses to emphasize development of these lower-order skills, student performances in Close Readings would also be improved. This did turn out to be the case. Most of the supporting data is qualitative rather than quantitative. -/- It is recommended that similar activities be continued, but that participating faculty be required to provide much more prescriptively structured and detailed assessment data and information about their course design.

Intellectual attention, like perceptual attention, is a special mode of mental engagement with the world. When we attend intellectually, rather than making use of sensory information we make use of the kind of information that shows up in occurent thought, memory, and the imagination (Chun, Golomb, & Turk-Browne, 2011). In this paper, I argue that reflecting on what it is like to comprehend memory demonstratives speaks in favour of the view that intellectual attention is required to understand memory demonstratives. Moreover, (...) I argue that this is a line of thought endorsed by Gareth Evans in his Varieties of Reference (1982). In so doing, I improve on interpretations of Evans that have been offered by Christopher Peacocke (1984), and Christoph Hoerl & Theresa McCormack (a coauthored piece, 2005). In so doing I also improve on McDowell’s (1990) criticism of Peacocke’s interpretation of Evans. Like McDowell, I believe that Peacocke might overemphasize the role that “memory-images” play in Evans’ account of comprehending memory demonstratives. But unlike McDowell, I provide a positive characterization of how Evans described the phenomenology of comprehending memory demonstratives. (shrink)

What is the ontology of collective action? I have in mind three connected questions. 1. Do the truth conditions of action sentences about groups require there to be group agents over and above individual agents? 2. Is there a difference, in this connection, between action sentences about informal groups that use plural noun phrases, such as ‘We pushed the car’ and ‘The women left the party early’, and action sentences about formal or institutional groups that use singular noun phrases, such (...) as ‘The United States declared war on Japan on December 8th, 1941’ and ‘The Supreme Court ruled that segregation is unconstitutional in 1954 in Brown vs. Board of Education’? 3. Under what conditions does it make sense to speak of a group doing something together, and what, if anything, is a collective action? In this paper, I argue that a) understanding action sentences about groups does not commit us to the existence of group agents per se, but only to the existence of individual agents; b) there is no difference in this regard between sentences which attribute actions to informal groups on the one hand and institutional groups on the other; c) collective action can be both intentional and unintentional; d) any random group of agents each of whom does something is also a group which does something together; e) while there is a sense in which groups per se perform no primitive collective actions, and therefore no actions at all, f) there is a sensible extension of talk of actions to groups, though it should be treated strictly speaking, like talk of group agents, as a façon de parler, for g) the only agents per se are individuals and the only actions are theirs. -/-.

Deceased organ donation is widely considered as a case of easy rescue―that is, a case in which A may bestow considerable benefits on B while incurring negligent costs herself. Yet, the policy implications of this observation remain unclear. Drawing on Christopher H. Wellman’s samaritan account of political obligations, the paper develops a case for a so-called opt-out system, i.e., a scheme in which people are defaulted into being donors. The proposal’s key idea is that we may arrange people’s options (...) in specific ways for the sake of others. (shrink)

The goal of this paper is to sketch an account of Kant’s signature metaphysical doctrine (transcendental idealism) that (a) has no supporters – as far as I am aware – in the contemporary literature, and (b) draws its primary motivation (as interpretation) from considerations regarding our practical situation and needs as agents. -/- The consideration I focus on here is that people not only have mental and moral features, but they also appear to us – in our daily experience – (...) to have such features: “[w]e can perceive virtue in our experience (Wir können in der Erfahrung wohl Tugend wahrnehmen)” (24: 906). The same presumably goes for vice: When I see you casually torturing a cat, you appear to me to be brown-haired, wearing jeans, moving your arms, laughing, and so on, but you also appear to me to be vicious and cruel. Your character shines through in your actions. I can then make a defeasible inference from those appearances to the moral reality. -/- Such appearances and inferences play a central role in our practices of praise, blame, forgiveness, and punishment. An interpretation of transcendental idealism that gives primacy to the practical will thus seek to analyze the concepts of experience, acquaintance, and appearance/phenomenon in a capacious-enough way that they can apply to mental and moral features too. If successful, such an interpretation would have a clear practical advantage over those that leave us merely conjecturing from experiences of bodies, gestures, and secondary qualities to moral features that do not appear, or even to the non-appearing features of a distinct set of things.

This article analyses in detail Wittgenstein’s ‘Cambridge period’ from his return to Cambridge in 1929 until his decease in 1951. Within the ‘Cambridge period’, scholars usually distinguish the ‘middle’ (1929–1936) and the ‘late’ (1936–1951) periods. The trigger point of Wittgenstein’s return to Cambridge and philosophy was his visit to Brouwer’s lecture on ‘Mathematics, Science, and Language’ in Vienna in March 1928. Dutch mathematician Brouwer influenced not only Wittgenstein’s ability to do philosophy again but also the development of some of his (...) ideas. Namely, for Brouwer, language was a natural development of the social history of human beings. With the help of his friends, F. P. Ramsey, J. M. Keynes, G. E. Moore, and B. Russell, in 1929 Wittgenstein returned to Cambridge. The author argues that this was the crucial turning point in his philosophy that led to the revision of some of his ideas. Wittgenstein returned from self-isolation in remote villages of Lower Austria to the intellectual academic environment, where he could discuss his ideas with intellectual interlocutors and receive their valuable remarks and comments. This article is organised in chronological order: it describes the very ‘early’ middle period of 1929–1935 involving the development of Wittgenstein’s ‘phenomenology’ and the origin of the ‘language-games’ concept in the Blue and Brown Books; 1935–1936 period of ‘romantic’ enthusiasm for Soviet Russia and a trip there; Wittgenstein’s life and work during the WWII-time; resign from teaching in Cambridge in 1947 to finally finish his Philosophical Investigations. The author suggests that the ‘romantic areal’ about the USSR was formed by Wittgenstein’s predilection for Russian poetry and literature of the nineteenth century, i.e., Tolstoy, Dostoevsky, and Pushkin. Analysing the development of Wittgenstein’s ideas on language in his Cambridge period, the author mentions the influence of N. Bakhtin and P. Sraffa. Also, the author touches upon the topic of the possibility of Marxism’s influence on Wittgenstein’s life and thought. (shrink)

I intend to argue that the counterexamples inspired by the Frankfurt-type cases against the necessity of an epistemic safety condition for knowledge are not plausible. The epistemic safety condition for knowledge is a modal condition recently supported by Sosa (2007) and Pritchard (2015), among others, and can be formulated as follows: (SC) If S knows that p on basis B, then S’s true belief that p could not have easily been false on basis B. I will try to argue that (...) the safety condition, expressed in (SC), is still necessary for knowledge and that, therefore, epistemic safety is not threatened by Frankfurt-type cases. In particular, I want to show that Kelp’s counterexamples are ineffective against (SC). (shrink)

Sheep production is the most representative livestock activities in Brazil and in the world. However, the reproductive performance of these animals is determined by factors genetic, physical environment, management and, especially, nutritional. Thirty half-breed lambs from Dorper × Santa Inês were used, with initial weight and age of 31.87 ± 0.5 kg and 157 days, respectively. These animals were prepared on a diet with three food levels (ad libitum, 30% and 70%). Morphometric measurements were measured at intervals of 16 to (...) 20 days in 56 experimental days. The measurements performed were scrotal circumference (CE), chest circumference (CT), body condition score (ECC), withers height (AC) and scrotal bag thickness (EBE), body weight (CP) and semen collection. Interaction occurrence for biometric measurements between food levels and age (p <0.05). The TC and ECC values were higher in animals fed ad libitum (p <0.001). EBE had higher values in animals ad libitum and at 211 days of age (p <0.001). The CP was increasing for the animals ad libitum and (p <0.05) throughout the experiment, while the T30 was only in the initial period. T70 animals did not grow during the whole experiment. CE was influenced by diet (p <0.001) and age (p <0.001) independently. So that animals under food restriction had less development and was higher in older animals. The AC values were influenced only by age (p <0.001), demonstrating the effect of age growth. We conclude that it is not advantageous to submit lambs, it corrects food reproduction. Although it was not possible to assess whether initial malnutrition would bring future problems for the animal's seminal quality, it proved to be immensely negative for the onset of puberty and the development of reproductive structures. -/- REFERÊNCIAS BIBLIOGRÁFICAS AKUMBUGU, F.
