Smarandache in 2019 has generalized the algebraic structures to NeutroAlgebraic structures and AntiAlgebraic structures. In this paper, authors, for the first time, define the NeutroAlgebra of neutrosophic triplets group under usual+ and x, built using {Zn, x}, n a composite number, 5 < n < oo, which are not partial algebras. As idempotents in Zn alone are neutrals that contribute to neutrosophic triplets groups, we analyze them and build NeutroAlgebra of idempotents under usual + and x, which are not partial (...) algebras. We prove in this paper the existence theorem for NeutroAlgebra of neutrosophic triplet groups. This proves the neutrals assocaited with neutrosophic triplet groups in { Zn, X} under product is a NeutroAlgebra of triplets. We also prove the non-existence theorem of NeutroAlgebra for neutrosophic triplets in case of Zn when n = 2p, 3p and 4p (for some primes p). Several open problems are proposed. Further, the NeutroAlgebras of extended neutrosophic triplet groups have been obtained. (shrink)

RESUMO Os cuidados para atender às necessidades específicas da fêmea gestante são indispensáveis para o sucesso no manejo reprodutivo de qualquer espécie. Entretanto, é necessário entender que podem acontecer problemas em qualquer uma das fases reprodutivas, inclusive na gestação. Antes de tudo, na clínica e na produção, a sobrevivência dos fetos significa êxito no manejo reprodutivo. Durante o período gestacional podem se desenvolver diversas afecções no útero da fêmea, dentre elas podem ser citadas: mumificação fetal, gravidez ectópica, maceração fetal, prenhez (...) múltipla patológica e diversas anomalias que podem acometer os envoltórios e líquidos fetais. Essas doenças representam prognóstico ruim para a fêmea e para o feto, podendo resultar em perdas fetais. O conhecimento acerca das características dessas afecções, bem como a fisiopatologia e diagnóstico são indispensáveis para o sucesso da reprodução animal. Palavras-chave: Ginecologia, reprodução, gestação. ABSTRACT Care to meet the specific needs of pregnant females is essential for the successful reproductive management of any species. However, it is necessary to understand that problems may occur in any of the reproductive stages, including pregnancy. First of all, in the clinic and production, the survival of fetuses means success in reproductive management. During the gestational period, several pathological conditions can develop in the female uterus, among them fetal mummification, ectopic pregnancy, fetal maceration, pathological multiple pregnancy, and the various anomalies that can affect fetal envelopes and fluids. These illnesses represent a poor prognosis for the female and the fetus and may result in fetal loss. Knowledge about the characteristics of these conditions, as well as the pathophysiology and diagnosis are essential for the success of animal reproduction. Keywords: Gynecology, reproduction, gestation. -/- INTRODUÇÃO Na fisiologia da reprodução nos mamíferos, a implantação e a placentação são processos essenciais na nutrição do embrião e do feto e do seu desenvolvimento. Nos bovinos leiteiros, estima-se uma taxa de fertilização de 95%, com apenas 55% desses zigotos se desenvolvendo a termo e com perda de gestações de 35% (SILVA, 2021). Em equinos varia entre 5 e 15% (BRINSKO et al., 2011) e em suínos chega a 40% (VAN DER LENDE et al., 1994). A reprodução permite a manutenção do equilíbrio biótico, entretanto, falhas podem ocorrer, desde a concepção até o parto, incapacitando o pleno desenvolvimento gestacional e acarretando danos à cadeia produtiva (BRAGA e BARROSO, 2014). A taxa de perda gestacional atinge o pico durante o desenvolvimento embrionário e diminui após 45 dias, à medida que a gestação progride e a placentação ativa está completa (REESE et al., 2020). A placenta permite contato vascular eficaz entre as membranas fetais e o endométrio materno, através do qual ocorre a troca de oxigênio e de nutrientes vindos pelo sangue materno, além dos produtos de excreção do sangue fetal. Ela apresenta quatro membranas: a) âmnio, que contém o fluido amniótico que banha o embrião; b) saco vitelínico, que armazena os nutrientes; c) saco alantoide, onde os restos do metabolismo embrionário são estocados e d) córion, que delimita os limites do embrião e interage seletivamente com o ambiente externo, permitindo nutrientes e/ou oxigênio cheguem ao embrião (SILVA, 2020). No aparelho reprodutivo feminino as estruturas internas são presas pelo ligamento mesovário, que sustenta o ovário; o mesossalpinge, que ancora o oviduto e o mesométrio, que mantém o útero no seu lugar. Ele compreende os ovários, tubas, útero, cérvix, vagina, vestíbulo e vulva (KÖNIG e LIEBICH, 2021). O útero é formado por dois cornos, na região mesogástrica, que formam o corpo uterino, dorsal a vesícula urinária e ventral ao cólon descendente (PINTO e LORIGADOS, 2015). A cérvix fica na região caudal do útero (DYCE, 2019) e é composta pelo óstio uterino interno e o externo (KÖNIG e LIEBICH, 2021). O líquido amniótico é um complexo biológico que proporciona proteção mecânica, nutrientes e substâncias para o crescimento fetal e possui efeito antimicrobiano (UNDERWOOD et al., 2005). Ele desempenha várias funções: protege o feto contra traumas, desidratação e mudanças de temperatura; permite o desenvolvimento fetal e sua mobilidade; amplia a lubrificação da vagina após a ruptura da bolsa, inibe o crescimento bacteriano por ação mecânica de limpeza e previne aderências (GRUNERT e BIRGEL, 1984). As enfermidades do trato reprodutivo têm causado problemas reprodutivos, acarretando perdas econômicas (JÚNIOR et al., 2009). Os problemas na esfera da fisiopatologia da reprodução em animais, está associada ao período do periparto (SCOTT, 2005). Entretanto, existem relatos de sua ocorrência em fêmeas não gestantes e também fora do período puerperal (PRESTES et al., 2008; SALES et al., 2011). Devido à importância das diversas patologias que atingem o útero gravídico, esse trabalho tem como objetivo buscar identificar na literatura científica existente as características, diagnóstico e tratamento de cada alteração uterina, pautando discussão crítica sobre os processos de formação de cada uma.

On the received view, counterfactuals are analysed using the concept of closeness between possible worlds: the counterfactual 'If it had been the case that p, then it would have been the case that q' is true at a world w just in case q is true at all the possible p-worlds closest to w. The degree of closeness between two worlds is usually thought to be determined by weighting different respects of similarity between them. The question I consider in the (...) paper is which weights attach to different respects of similarity. I start by considering Lewis's answer to the question and argue against it by presenting several counterexamples. I use the same examples to motivate a general principle about closeness: if a fact obtains in both of two worlds, then this similarity is relevant to the closeness between them if and only if the fact has the same explanation in the two worlds. I use this principle and some ideas of Lewis's to formulate a general account of counterfactuals, and I argue that this account can explain the asymmetry of counterfactual dependence. The paper concludes with a discussion of some examples that cannot be accommodated by the present version of the account and therefore necessitate further work on the details. (shrink)

Evidential decision theory (EDT) says that the choiceworthiness of an option depends on its evidential connections to possible outcomes. Causal decision theory (CDT) holds that it depends on your beliefs about its causal connections. While Newcomb cases support CDT, Arif Ahmed has described examples that support EDT. A new account is needed to get all cases right. I argue that an option A's choiceworthiness is determined by the probability that a good outcome ensues at possible A‐worlds that match actuality in (...) the facts causally unaffected by your decision (the “unaffected facts”). Moreover, you should evaluate A on the assumption that A is compossible with the unaffected facts. This view entails that you should use EDT when evaluating A on the assumption that the unaffected facts determine your action, but use CDT when assessing A on the opposite assumption. A's choiceworthiness equals a weighted average of these conditional assessments. The weights are determined by your beliefs about whether the unaffected fact determine your action. This account gets both Newcomb and Ahmed cases right. According to an influential view, whether you take the unaffected facts to determine your action can make a difference to whether you can regard yourself as free and the action as being under your control. While my account is neutral on this issue, it entails that whether you take the unaffected facts to determine your action is important in a different way: it matters to whether you should follow EDT or CDT.

During the last quarter of a century, a number of philosophers have become attracted to the idea that necessity can be analyzed in terms of a hyperintensional notion of essence. One challenge for proponents of this view is to give a plausible explanation of our modal knowledge. The goal of this paper is to develop a strategy for meeting this challenge. My approach rests on an account of modality that I developed in previous work, and which analyzes modal properties in (...) terms of the notion of a metaphysical law. I discuss what information about the metaphysical laws is required for modal knowledge. Moreover, I describe two ways in which we might be able to acquire this information. The first way employs inference to the best explanation. The metaphysical laws, including the essential truths, play a crucial role in causal and grounding explanations and we can gain knowledge of these laws by abductive inferences from facts of which we have perceptual or a priori knowledge. The second way of gaining information about the metaphysical laws rests on knowledge that is partly constitutive of competence with the concepts that are needed to express the relevant information. Finally, I consider how knowledge of the metaphysical laws can be used to establish modal claims, paying special attention to the much-discussed connection between conceiving and possibility.

Aristotle’s aitiai are middle terms in Aristotelian syllogisms. I argue that stating the aitia of a thing therefore amounts to re-describing this same thing in an alternative and illuminating way. This, in turn, means that a thing and its aitiai really are one and the same thing under different descriptions. The purpose of this paper is to show that this view is implied by Aristotle’s account of explanation, and that it makes more sense than one might expect.

The Russell-Myhill paradox puts pressure on the Russellian structured view of propositions by showing that it conflicts with certain prima facie attractive ontological and logical principles. I describe several versions of RMP and argue that structurists can appeal to natural assumptions about metaphysical grounding to provide independent reasons for rejecting the ontological principles used in these paradoxes. It remains a task for future work to extend this grounding-based approach to all variants of RMP.

Many philosophers and non-philosophers who reflect on the causal antecedents of human action get the impression that no agent can have morally relevant freedom. Call this the ‘non-existence impression.’ The paper aims to understand the (often implicit) reasoning underlying this impression. On the most popular reconstructions, the reasoning relies on the assumption that either an action is the outcome of a chance process, or it is determined by factors that are beyond the agent’s control or which she did not bring (...) about. I argue that arguments based on this premise fail to apply to some possible agents for whom the non-existence impression arises. On the alternative reconstruction I offer, the impression rests on the assumption that free will requires being involved in the ultimate explanation of one’s actions in a novel sense in which nothing can be involved in the ultimate explanation of anything.

In this handbook, I put into practice my philosophical views on children's mathematics. The handbook contains brief instructions and examples of mathematical activities. In the INSTRUCTIONS section, instructions are given on how, and in part why that way, to help preschool children in their mathematical development. In the ACTIVITIES section, there are examples of activities through which the child develops her mathematical abilities.

The global water crisis is being exacerbated by climate change, even in the United States. Recycled water is a feasible alternative to alleviate the water shortage, but it is constrained by humans’ perceptions. The current study examines how residents’ water scarcity awareness and climate change belief influence their willingness to use recycled water directly and indirectly. Bayesian Mindsponge Framework (BMF) analytics was employed on a dataset of 1831 residents in Albuquerque, New Mexico, an arid inland region in the US. We (...) discovered that residents’ willingness to use direct recycled potable water is positively affected by their awareness of water scarcity, but only if they believe in the impacts of climate change on the water cycle. Meanwhile, the willingness to use indirect recycled potable water is influenced by water scarcity awareness, and the belief in climate change further enhances this effect. These findings implicate that fighting climate change denialism and informing the public of the water scarcity situation in the region can contribute to the effectiveness and sustainability of long-term water conservation and climate change alleviation efforts.

Much of the modern philosophy of causation has been governed by two ideas: (i) causes make their effects inevitable; (ii) a cause is something that makes a difference to whether its effect occurs. I focus on explaining the origin of idea (ii) and its connection to (i). On my view, the frequent attempts to turn (ii) into an analysis of causation are wrongheaded. Patterns of difference-making aren't what makes causal claims true. They merely provide a useful test for causal claims. (...) Moreover, what justifies us in using them as a test is idea (i). That's how (i) and (ii) are connected. (shrink)

The sample space of the chance distribution at a given time is a class of possible worlds. Thanks to this connection between chance and modality, one’s views about modal space can have significant consequences in the theory of chance and can be evaluated in part by how plausible these implications are. I apply this methodology to evaluate certain forms of modal contingentism, the thesis that some facts about what is possible are contingent. Any modal contingentist view that meets certain conditions (...) that I specify generates difficulties in the philosophy of chance, including a problem usually associated with Humeanism that is known as ‘the problem of undermining futures’. I consider two well-known versions of modal contingentism that face this difficulty. The first version, proposed by Hugh Chandler and Nathan Salmon, rests on an argument for the claim that many individuals have their modal features contingently. The second version is motivated by the thesis that the existence of a possible world depends on the existence of the contingent individuals inhabiting it, and that many worlds are therefore contingent existents.

The current assessment of behaviors in the inventories to diagnose autism spectrum disorders (ASD) focus on observation and discrete categorizations. Behaviors require movements, yet measurements of physical movements are seldom included. Their inclusion however, could provide an objective characterization of behavior to help unveil interactions between the peripheral and the central nervous systems. Such interactions are critical for the development and maintenance of spontaneous autonomy, self-regulation and voluntary control. At present, current approaches cannot deal with the heterogeneous, dynamic and stochastic (...) nature of development. Accordingly, they leave no avenues for real-time or longitudinal assessments of change in a coping system continuously adapting and developing compensatory mechanisms. We offer a new unifying statistical framework to reveal re-afferent kinesthetic features of the individual with ASD. The new methodology is based on the non-stationary stochastic patterns of minute fluctuations (micro-movements) inherent to our natural actions. Such patterns of behavioral variability provide re-entrant sensory feedback contributing to the autonomous regulation and coordination of the motor output. From an early age, this feedback supports centrally driven volitional control and fluid, flexible transitions between intentional and spontaneous behaviors. We show that in ASD there is a disruption in the maturation of this form of proprioception. Despite this disturbance, each individual has unique adaptive compensatory capabilities that we can unveil and exploit to evoke faster and more accurate decisions. Measuring the kinesthetic re-afference in tandem with stimuli variations we can detect changes in their micro-movements indicative of a more predictive and reliable kinesthetic percept. Our methods address the heterogeneity of ASD with a personalized approach grounded in the inherent sensory-motor abilities that the individual has already developed. (shrink)

Analysing several characteristic mathematical models: natural and real numbers, Euclidean geometry, group theory, and set theory, I argue that a mathematical model in its final form is a junction of a set of axioms and an internal partial interpretation of the corresponding language. It follows from the analysis that (i) mathematical objects do not exist in the external world: they are our internally imagined objects, some of which, at least approximately, we can realize or represent; (ii) mathematical truths are not (...) truths about the external world but specifications (formulations) of mathematical conceptions; (iii) mathematics is first and foremost our imagined tool by which, with certain assumptions about its applicability, we explore nature and synthesize our rational cognition of it.

In this article I develop an elementary system of axioms for Euclidean geometry. On one hand, the system is based on the symmetry principles which express our a priori ignorant approach to space: all places are the same to us, all directions are the same to us and all units of length we use to create geometric figures are the same to us. On the other hand, through the process of algebraic simplification, this system of axioms directly provides the Weyl’s (...) system of axioms for Euclidean geometry. The system of axioms, together with its a priori interpretation, offers new views to philosophy and pedagogy of mathematics: it supports the thesis that Euclidean geometry is a priori, it supports the thesis that in modern mathematics the Weyl’s system of axioms is dominant to the Euclid’s system because it reflects the a priori underlying symmetries, it gives a new and promising approach to learn geometry which, through the Weyl’s system of axioms, leads from the essential geometric symmetry principles of the mathematical nature directly to modern mathematics.

Approximate coherentism suggests that imperfectly rational agents should hold approximately coherent credences. This norm is intended as a generalization of ordinary coherence. I argue that it may be unable to play this role by considering its application under learning experiences. While it is unclear how imperfect agents should revise their beliefs, I suggest a plausible route is through Bayesian updating. However, Bayesian updating can take an incoherent agent from relatively more coherent credences to relatively less coherent credences, depending on the (...) data observed. Thus, comparative rationality judgments among incoherent agents are unduly sensitive to luck. (shrink)

Purpose. To determine the potential of deforming broaching for the improvement of efficiency of cutter chisels in the mining industry. Methodology. The study of the application of the technological process of deforming broaching was carried out based on the experimental research into conditions of assembly of press couplings corresponding to cutting rock-destroying tools, the working surface of which is reinforced with solid-alloy inserts. Findings. Based on the conducted research, a new process of assembling the crowns of cutter chisels with the (...) use of deforming broaching was developed. Originality. It was determined that the range of angles of inclination of generatrix of the working cone of the deforming element and the roll-treading lip of the insert, which are necessary for efficient machining and pressing in crowns of cutters, is 4–16°. It was proven that the “solid alloy-steel” press couplings for cutter chisels will have the maximum bearing capacity at total tension a/d0 ≤ 3 %. It was found that it is necessary to foresee the following distribution of tensions: to perform 2 % of deformation by preliminary deforming broaching, and 1 % ‒ by pressing in an insert Practical value. The use of deforming broaching makes it possible to increase the strength of fastening the inserts of cutter chisels by 2 times, to reduce specific consumption of the tool by 4.4 times, and to increase the average drilling rate by 4 times.

Initial responses to questionnaires used to assess participants' understanding of informed consent for malaria vaccine trials conducted in the United States and Mali were tallied. Total scores were analyzed by age, sex, literacy (if known), and location. Ninety-two percent (92%) of answers by United States participants and 85% of answers by Malian participants were correct. Questions more likely to be answered incorrectly in Mali related to risk, and to the type of vaccine. For adult participants, independent predictors of higher scores (...) were younger age and female sex in the United States, and male sex in Mali. Scores in the United States were higher than in Mali (P = 0.005). Despite this difference participants at both sites were well informed overall. Although interpretation must be qualified because questionnaires were not intended as research tools and were not standardized among sites, these results do not support concerns about systematic low understanding among research participants in developing versus developed countries.

In this essay I defend the claim that the life of a living being is not one of its properties but something different: a mode of being. It follows from this that living beings should not be taken to be things that possess the property of being alive. Second, I argue that living beings are essentially involved in ongoing activities as long as they exist. Life cannot only be a disposition to be active, but must itself be an ongoing activity. (...) Third, I suggest that for something to be a living being is to engage in activities whose success is determined by criteria that emerge exclusively from a proper account of the nature of the living being in question. To identify something as a living being is not to attribute a particular property to it, but to say what criteria apply to what it actually is or does. (shrink)

The giant strides to be taken in becoming an academic do not just entail acquiring knowledge through formal education but demand further steps to master, philosophize and profess knowledge. Apart from the credentials to show that quality conditions were fulfilled in a higher education, volumes of well researched publications in peer review academic journals are vital. In Nigeria, when this form of learning came through colonial education women were not as privileged as men to acquire it immediately. So, men become (...) educated first, hence were the first set of academics. Subsequently, women joined this league of educated men in the academic world. The utilization of this knowledge by both men and women in academic community encroached on culture, its administration and expression. In this instance, issues in various endeavours, including academics are expressed through culture of criticism and criticism of culture. This study examines women’s academic world and their efforts in criticizing Nigerian culture with a focus on Mabel Evwierhoma’s involvement using theatre scholarship. The theory of Cultural Studies as it relates to cultural criticism specifically feminist criticism will be adopted to explore cultural feminist thoughts of Nigerian women in the academics with Evwierhoma’s input as a focus. The study finds that since the inception of feminism in Nigeria, women have deployed its scholarship, to criticise culture. Women in the theatre have used every available tool including creative writing, critical writing, research, pedagogy and philosophy to highlight cultural values that favour women. Evwierhoma has made a robust impact in this regard. (shrink)

I defend the following version of the ought-implies-can principle: (OIC) by virtue of conceptual necessity, an agent at a given time has an (objective, pro tanto) obligation to do only what the agent at that time has the ability and opportunity to do.

My argument has three premises: (1) obligations correspond to reasons for action; (2) reasons for action correspond to potential actions; (3) potential actions correspond to ability plus opportunity. In the (...) bulk of the paper I address six objections to OIC: three objections based on putative counterexamples, and three objections based on arguments to the effect that OIC conflicts with the is/ought thesis, the possibility of hard determinism, and the denial of the Principle of Alternate Possibilities.

The desire for the inner feeling of existence was central to Heidegger’s later philosophy. During the 1930s in works like the Contributions to Philosophy, he began to search for the direct experience, rather than the mere knowledge, of existential power. I characterize such feelings as post-Lutheran. Luther taught his followers to feel the presence of an existentially creative God within themselves. Such feelings, as evidence of one’s salvation, became endemic. After the Enlightenment and despite the rise of secularism, the desire (...) for the inner feeling of existence remained within portions of German culture. Heidegger rejected the idea of God as the foundation of existence, which he called an ontotheology, but he retained the desire to experience the coming-to-be of existence as an inner activity. In the Contributions, Heidegger repeatedly describes Being or “Seyn” as the “trembling” or “oscillation” between existence and nothingness. He tells us that nothingness always remains central to Being, which is what distinguishes Being from mere beings. The latter belong only to what has come-to-be; what Heidegger wanted to experience, not intellectually but as an inner feeling, was the power of coming-to-be. In short, Heidegger sought the inner experience of coming into being from nothingness. (shrink)

In this paper, I argue that self-awareness is intertwined with one's awareness of possibilities for action. I show this by critically examining Dan Zahavi's multidimensional account of the self. I argue that the distinction Zahavi makes among 'pre-reflective minimal', 'interpersonal', and 'normative' dimensions of selfhood needs to be refined in order to accommodate what I call 'pre-reflective self-understanding'. The latter is a normative dimension of selfhood manifest not in reflection and deliberation, but in the habits and style of a person’s (...) pre-reflective absorption in the world. After reviewing Zahavi's multidimensional account and revealing this gap in his explanatory taxonomy, I draw upon Heidegger, Merleau-Ponty, and Frankfurt in order to sketch an account of pre-reflective self-understanding. I end by raising an objection to Zahavi’s claim for the primitive and foundational status of pre-reflective self-awareness. To carve off self-awareness from the self’s practical immersion in a situation where things and possibilities already matter and draw one to act is to distort the phenomena. A more careful phenomenology of pre-reflective action shows that pre-reflective self-awareness and pre-reflective self-understanding are co-constitutive, both mutually for each other and jointly for everyday experience.

If time travel is possible, presumably so is my shooting my younger self ; then apparently I can kill him – I can commit retrosuicide. But if I were to kill him I would not exist to shoot him, so how can I kill him? The standard solution to this paradox understands ability as compossibility with the relevant facts and points to an equivocation about which facts are relevant: my killing YS is compossible with his proximity but not with his (...) survival, so I can kill him if facts like his survival are irrelevant but I cannot if they are relevant. I identify a lacuna in this solution, namely its reliance without argument on the hidden assumption that my killing YS is possible: if it is impossible, it is not compossible with anything. I argue that this lacuna is important, and I sketch a different solution to the paradox. (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)

The APA has recently taken steps to address concerns related to teaching and supporting philosophers and students who come from less privileged backgrounds.

In this paper, a modified form of Collatz conjecture for neutrosophic numbers n ∈ (Z U I) is defined. We see for any n ∈ (Z U I) the related sequence using the formula (3a + 1) + (3b + 1)I converges to any one of the 55 elements mentioned in this paper. Using the akin formula of Collatz conjecture viz. (3a- 1) + (3b -1)I the neutrosophic numbers converges to any one of the 55 elements mentioned with appropriate modifications. (...) Thus, it is conjectured that every n ∈ (Z U I) has a finite sequence which converges to any one of the 55 elements. (shrink)

In the wake of the advent of genome editing technology CRISPR-Cas9 (clustered regularly interspaced palindromic repeat (CRISPR)-associated protein 9), there has been a global debate around the implications of manipulating the human genome. While CRISPR-based germline gene editing is new, the debate about the ethics of gene editing is not – for several decades now, scholars have debated the ethics of making heritable changes to the human genome. The arguments that have been raised both for and against the use of (...) genetic technologies in human reproduction reiterate much of the arguments made in the pre-CRISPR debate. As such, it is instructive for South Africa to reflect on these arguments now, in considering our position on the regulation of the use of this novel biotechnology. There are two dominant schools of thought in this area, bioliberalism and bioconservatism. Bioconservatives raise concerns about the risks of genetic manipulation, and argue that it ought to be limited or prohibited to avert these risks to human health and human nature. Bioliberal scholars are more open to the prospect of genetic manipulation, because of its potential utility. In this article, I conclude that in liberal democracies such as our own, bioliberal arguments ought to be seriously considered when formulating policy on human genome editing because of the extent to which they resonate with our Constitutional values and human rights. I further suggest that there is a need for an enquiry into the relevance of African perspectives on the ethical questions that arise concerning germline genome editing. (shrink)

Influential cases have been provided that seem to suggest that one can fail to have knowledge because of the social environment. If not a distinct kind of social defeater, is there a uniquely social phenomenon that defeats knowledge? My aim in this paper is to explore these questions.

We can explain putative cases (...) of social defeat with our existing epistemological apparatus. (shrink)

Early Heidegger argues that a “homogenous space of nature” can be revealed by stripping away the intelligibility of Dasein's everyday world, a process he calls “deworlding.” Given this, some interpreters have suggested that Heidegger, despite not having worked out the details himself, is also committed to a notion of deworlded time. Such a “natural time” would amount to an endogenous sequentiality in which events are ordered independently of Dasein and the stand it takes on its being. I show that Heidegger (...) was indeed committed to such a temporal realism even though his treatment of these issues is somewhat scattered and pulled in different directions. In the course of my reconstruction, I renew an interpretation of Heidegger that stresses Dasein's thrownness into nature and I answer William Blattner's powerful interpretation of Heidegger as a failed temporal idealist who was unable to derive the sequentiality of ordinary time from Dasein's non-sequential originary temporality. Heidegger did not attempt to derive sequentiality; instead, he understood it as a built-in feature of the natural universe by which Dasein's activities are constrained. World-time turns out to be a co-production of Dasein's non-sequential originary temporality and the endogenous sequentiality of events in nature. (shrink)

The New Evil Demon problem has been hotly debated since the case was introduced in the early 1980’s (e.g. Lehrer and Cohen 1983; Cohen 1984), and there seems to be recent increased interest in the topic. In a forthcoming collection of papers on the New Evil Demon problem (Dutant and Dorsch, forthcoming), at least two of the papers, both by prominent epistemologists, attempt to resist the problem by appealing to the distinction between justification and excuses. My primary aim here is (...) to critically evaluate this new excuse maneuver as a response to the New Evil Demon problem. -/- Their response attempts to give us reason to reject the idea that victims of the New Evil Demon have justification for believing as they do. I shall argue that this approach is ultimately unsuccessful, however much of value can be learned from these attempts. In particular, progress in the debate can be made by following those who advance the excuse maneuver and make explicit the connection between epistemic justification and epistemic norms. By doing so, the questions being debated are clarified, as is the methodology being used to attempt to answer them. (shrink)

Both Martin Heidegger and Harry Frankfurt have argued that the fundamental feature of human identity is care. Both contend that caring is bound up with the fact that we are finite beings related to our own impending death, and both argue that caring has a distinctive, circular and non-instantaneous, temporal structure. In this paper, I explore the way Heidegger and Frankfurt each understand the relations among care, death, and time, and I argue for the superiority of Heideggerian version of this (...) nest of claims. Frankfurt claims that we should conceive of the most basic commitments which practically orient a person in the world and define his identity (“volitional necessities”) as naturalistic facts, foundational for and located completely without the normative space of reasons. In support of this he appeals to the supposedly foundational role played in human life by the instinct for self-preservation, what Frankfurt calls the “love of living.” The claim is that in questions of practical identity there is a definite priority of the factual over the normative. Frankfurt’s naturalistic model of volitional necessity is motivated by a misunderstanding of the temporal structure of care, a misunderstanding that helps lead him to an implausible conception of the basic structures of human identity. Heidegger advances an anti-naturalistic conception of caring, one bound up with his way of understanding how human beings relate to their own future. I argue that the existential, temporal, and normative significance that Frankfurt attributes to the naturalized “love of living” is better captured by the Heideggerian claim that human identity is defined by being “for-the-sake-of” certain projects and commitments, a way of being lived out in the way Heidegger calls “being-towards-death.”.

My interest lies in offering a phenomenological perspective on how noise is experienced, with particular attention to what may be common to different sorts of noise phenomena. As a counterpoint to the notion that noise is an empty or constructed notion, I argue for two desiderata of a phenomenological account of noise; accommodating a plurality of noise experiences, on the one hand, and clarifying their specific phenomenal character, on the other. I then pursue these desiderata by turning to an examination (...) of some contemporary views of perception that have implications for how the phenomenal character of perceptual noise in particular is to be understood; an epistemic misfire view and a sensory misfire view. After clarifying each and its appeal, I convey concerns about the one and the other. I propose a third alternative for further exploration - a perceptual disjoint view - and point to how it ought to explored. On the premise that there is something like a unity of consciousness or experience, I lay out the idea that there may then be many forms of 'disunities' of experience. From an analysis of the latter, I suggest, one may account for many different types of experiences of noise, though with a common ‘phenomenal’ thread running through them. (shrink)

This paper provides an interpretation of the existential conception of selfhood that follows from Merleau-Ponty’s account of perception. On this view, people relate to themselves not by “looking within” in acts of introspection but, first, by “looking without” at the field of solicitations in which they are immersed and, eventually, in Merleau-Ponty’s words, by “making explicit” the “melodic unity” or “immanent sense” of their behavior. To make sense of this, I draw out a distinction latent in Merleau-Ponty’s view between a (...) pre-reflective sense of self and a reflective self-interpretation. The former is a suite of abilities and dispositions in light of which a person is aware of and drawn to act in a situation. This sense of self undergoes transitions over time, is constitutively susceptible to moments of disorientation, and tends toward but never achieves full coherence. Reflective self-interpretation is an activity whereby someone—provisionally and defeasibly—clarifies, articulates, and gets a better “grip” on how they are prereflectively drawn to act. I ground this interpretation in a detailed reading of Merleau-Ponty’s treatment of romantic love and I corroborate it by examining his account of the emergence of class-consciousness in the self-interpretation of a worker.

In this paper, I address some puzzles about Frege’s conception of how we “grasp” thoughts. I focus on an enigmatic passage that appears near the end of Frege’s great essay “The Thought.” In this passage Frege refers to a “non-sensible something” without which “everyone would remain shut up in his inner world.” I consider and criticize Wolfgang Malzkorn’s interpretation of the passage. According to Malzkorn, Frege’s view is that ideas [Vorstellungen] are the means by which we grasp thoughts. My counter-proposal (...) is that language enables us to grasp thoughts (ideas are merely their baggage or “trappings,” as Frege puts it). One significant consequence of my interpretation is that it helps challenge the standard reading of Frege according to which he is a metaphysical platonist about thoughts. My interpretation thus provides support for the deflationary, anti-ontological reading spelled out by readers like Thomas Ricketts and Wolfgang Carl. As Ricketts puts it, Frege’s distinction between the objective and the subjective, rather than being an ontological doctrine, “lodges in the contrast between asserting something and giving vent to a feeling.”.

According to Heidegger's Being and Time, social relations are constitutive of the core features of human agency. On this view, which I call a ‘strong conception’ of sociality, the core features of human agency cannot obtain in an individual subject independently of social relations to others. I explain the strong conception of sociality captured by Heidegger's underdeveloped notion of ‘being-with’ by reconstructing Heidegger's critique of the ‘weak conception’ of sociality characteristic of Kant's theory of agency. According to a weak conception, (...) sociality is a mere aggregation of individual subjects and the core features of human agency are built into each individual mind. The weak conception of sociality remains today widely taken for granted. I show that Christine Korsgaard, one of the most creative contemporary appropriators of Kant, operates with a weak conception of sociality and that this produces a problematic explanatory deficiency in her view: she is unable to explain the peculiar motivational efficacy of shared social norms. Heidegger's view is tailor made to explain this phenomenon. I end by sketching how Heidegger provides a social explanation of a major systematic concern animating Korsgaard, the concern with the importance of individual autonomy and answerability in human life.

Does the recent success of Podemos and Syriza herald a new era of inclusive, egalitarian left populism? Because leaders of both parties are former students of Ernesto Laclau and cite his account of populism as guiding their political practice, this essay considers whether his theory supports hope for a new kind of populism. For Laclau, the essence of populism is an “empty signifier” that provides a means by which anyone can identify with the people as a whole. However, the concept (...) of the empty signifier is not as neutral as he assumes. As I show by analyzing the role of race in his theory, some subjects are constituted in a way that prevents their unmediated identification with the people. Consequently, Laclau’s view should be read as symptomatic of the problems with populist logic if its adherents are to avoid reproducing its exclusions and practice a more inclusive politics.

Proponents of the problem of animal suffering claim that the millions of years of apparent nonhuman animal pain and suffering provides evidence against the existence of God. Neo-Cartesianism attempts to avoid this problem mainly by denying the existence of phenomenal consciousness in nonhuman animals. However, neo-Cartesian options regarding animal minds have failed to compel many. In this essay, I explore an answer to the problem of animal suffering inspired by the medieval theologian Thomas Aquinas. Instead of focusing on phenomenal consciousness, (...) the neo-Thomistic view of animal minds focuses on self-awareness. After proposing and providing evidence for this view, I conclude that nonhuman animal suffering is not morally significant. (shrink)

In common with traditional forms of epistemic internalism, epistemological disjunctivism attempts to incorporate an awareness condition on justification. Unlike traditional forms of internalism, however, epistemological disjunctivism rejects the so-called New Evil Genius thesis. In so far as epistemological disjunctivism rejects the New Evil Genius thesis, it is revisionary. -/- After explaining what epistemological disjunctivism is, and how it relates to traditional forms of epistemic internalism / externalism, I shall argue that the epistemological disjunctivist’s account of the intuitions underlying the New (...) Evil Genius thought experiment is at best incomplete. As presented, therefore, epistemological disjunctivism is unable to accommodate the core guiding intuitions of epistemic internalism. Given the stated aim of not being revisionary on this score, the view is at a dialectical disadvantage over the traditional forms of epistemic internalism the position is meant to replace. Unfortunately, therefore, at present, the impasse between internalism and externalism remains. (shrink)

Imperatives cannot be true or false, so they are shunned by logicians. And yet imperatives can be combined by logical connectives: "kiss me and hug me" is the conjunction of "kiss me" with "hug me". This example may suggest that declarative and imperative logic are isomorphic: just as the conjunction of two declaratives is true exactly if both conjuncts are true, the conjunction of two imperatives is satisfied exactly if both conjuncts are satisfied—what more is there to say? Much more, (...) I argue. "If you love me, kiss me", a conditional imperative, mixes a declarative antecedent ("you love me") with an imperative consequent ("kiss me"); it is satisfied if you love and kiss me, violated if you love but don't kiss me, and avoided if you don't love me. So we need a logic of three -valued imperatives which mixes declaratives with imperatives. I develop such a logic. (shrink)

In this article I argue that the value of epistemic justification cannot be adequately explained as being instrumental to truth. I intend to show that false belief, which is no means to truth, can nevertheless still be of epistemic value. This in turn will make a good prima facie case that justification is valuable for its own sake. If this is right, we will have also found reason to think that truth value monism is false: assuming that true belief does (...) have value, there is more of final epistemic value than mere true belief.

In its most basic form, Simple Reliabilism states that: a belief is justified iff it is formed as the result of a reliable belief-forming process. But so-called New Evil Demon cases have been given as counterexamples. A common response has been to complicate reliabilism from its simplest form to accommodate the basic reliabilist position, while at the same time granting the force of NED intuitions. But what if despite initial appearances, Simple Reliabilism, without qualification, is compatible with the NED intuition? (...) What we can call the Dispositionalist Response to the New Evil Demon problem is fascinating because it contends just that: Simple Reliabilism is fully compatible with the NED intuition. It is claimed that all we need to do to recognize their compatibility is appreciate that reliability is a dispositional property. In this paper I shall critically evaluate the Dispositionalist proposal. (shrink)

Philosophers have cataloged a range of genealogical methods by which different sorts of normative conclusions can be established. Although such methods provide diverging ways of pursuing genealogical inquiry, they typically converge in eschewing historiographic methodology, in favor of a uniquely philosophical approach. In contrast, one genealogist who drew on historiographic methodology is Michel Foucault. This article presents the motivations and advantages of Foucault's genealogical use of such a methodology. It advances two mains claims. First, that Foucault's early 1970s work employs (...) a distinct genealogical method, which borrows from contemporary historiographic models of explanation to expand the range of objects that are proper to genealogical accounts of historical change. I demonstrate how Foucault modifies two central commitments of Nietzsche by broadening the dimensions of genealogical inquiry and explanation. Second, that historical method has normative relevance for genealogy, insofar as different historiographic choices can lead to different normative conclusions. I motivate this second claim by explaining how Foucault's multidimensional genealogical method expands both (a) the range of objects that are subject to evaluative assessment, and (b) the set of possible prescriptive recommendations that follow from such assessment.

If knowledge requires safety, then one might think that when the epistemic source of knowledge is testimony, that testimony must itself be safe. Otherwise, will not the lack of safety transfer from testimony to hearer, such that hearer will lack knowledge? Resisting this natural line of reasoning, Goldberg (2005; 2007) argues that testimonial knowledge through unsafe testimony is possible on the basis of two cases. Lackey (2008) and Pelling (2013) criticize Goldberg’s examples. But Pelling goes on to provide his own (...) example that attempts to show that Goldberg’s thesis is true: one can gain safe testimonial belief from unsafe testimony. If any of these counterexamples were correct, they would undermine the main reason to think that knowledge based on unsafe testimony is impossible. My aim in this paper is to critically assess these arguments, and to consider the possibility of knowledge through unsafe testimony. Drawing a general moral from the analysis of these cases, I shall contend that it is impossible to acquire safe belief solely on the basis of unsafe testimony. If so, then testimonial knowledge based solely on unsafe testimony is impossible. (shrink)

Vice epistemology, as Quassim Cassam understands it, is the study of the nature, identity, and significance of the epistemic vices. But what makes an intellectual vice a vice? Cassam calls his own view “Obstructivism” – intellectual vices are those traits, thinking styles, or attitudes that systematically obstruct the acquisition, retention, and transmission of knowledge. -/- I shall argue that Cassam’s account is an improvement upon virtue-reliabilism, and that it fares better against what I call Montmarquet’s objection than its immediate rivals. (...) Nevertheless, I contend that it does not go far enough — Montmarquet’s objection stands. -/- I conclude that either the objection needs to be answered in some other way, or else proponents of Obstructivism need to explain why their account of the nature of the intellectual vices does not have the counterintuitive consequences it appears to have. Alternatively, another account of the nature of the intellectual vices needs to be sought. (shrink)
