Four studies measured or manipulated beliefs in free will to illuminate how such beliefs are linked to other aspects of personality. Study 1 showed that stronger belief in free will was correlated with more gratitude, greater life satisfaction, lower levels of perceived life stress, a greater sense of self-efficacy, greater perceived meaning in life, higher commitment in relationships, and more willingness to forgive relationship partners. Study 2 showed that the belief in free will was a stronger predictor (...) of life satisfaction, meaning in life, gratitude, and self-efficacy than either locus of control or implicit person theory. Study 3 showed that experimentally manipulating disbelief in free will caused a reduction in the perceived meaningfulness of life. Study 4 found that inducing a stronger belief in free will caused people to set more meaningful goals for themselves. The possible concern that believers in free will simply claim all manner of positive traits was contradicted by predicted null finding.. (shrink)

In our response to the 27 commentaries, we refine the theoretical claims, clarify several misconceptions of our framework, and explore substantial disagreements. In doing so, we show that our framework accommodates multiple historical scenarios; debate the historical evidence, particularly about “pre-Axial” religions; offer important details about cultural evolutionary theory; clarify the termprosociality;and discuss proximal mechanisms. We review many interesting extensions, amplifications, and qualifications of our approach made by the commentators.

We develop a cultural evolutionary theory of the origins of prosocial religions and apply it to resolve two puzzles in human psychology and cultural history: (1) the rise of large-scale cooperation among strangers and, simultaneously, (2) the spread of prosocial religions in the last 10–12 millennia. We argue that these two developments were importantly linked and mutually energizing. We explain how a package of culturally evolved religious beliefs and practices characterized by increasingly potent, moralizing, supernatural agents, credible displays of faith, (...) and other psychologically active elements conducive to social solidarity promoted high fertility rates and large-scale cooperation with co-religionists, often contributing to success in intergroup competition and conflict. In turn, prosocial religious beliefs and practices spread and aggregated as these successful groups expanded, or were copied by less successful groups. This synthesis is grounded in the idea that although religious beliefs and practices originally arose as nonadaptive by-products of innate cognitive functions, particular cultural variants were then selected for their prosocial effects in a long-term, cultural evolutionary process. This framework (1) reconciles key aspects of the adaptationist and by-product approaches to the origins of religion, (2) explains a variety of empirical observations that have not received adequate attention, and (3) generates novel predictions. Converging lines of evidence drawn from diverse disciplines provide empirical support while at the same time encouraging new research directions and opening up new questions for exploration and debate.

. Remarkably, despite the tremendous success of axiomatic set-theory in mathematics, logic and meta-mathematics, e.g., model-theory, two philosophical worries about axiomatic set-theory as the adequate catch of the set-concept keep haunting it. Having dealt with one worry in a previous paper in this journal, we now fulfil a promise made there, namely to deal with the second worry. The second worry is the Skolem Paradox and its ensuing Skolemite skepticism. We present a comparatively novel and simple analysis of the argument (...) of the Skolemite skeptic, which will reveal a general assumption concerning the meaning of the set-concept (we call it Connexion M). We argue that the Skolemite skeptics argument is a petitio principii and that consequently we find ourselves in a dialectical situation of stalemate.Few (if any) working set-theoreticians feel a tension – let alone see a paradox – between, on the one hand, what the Löwenheim–Skolem theorems and related results seem to be telling us about the set-concept, and, on the other hand, their uncompromising and successful use of the set-concept and their continuing enthusiasm about it, in other words: their lack of skepticism about the set-concept. Further, most (if not all) working settheoreticians have a relaxed attitude towards the ubiquitous undecidability phenomenon in set-theory, rather than a worrying one. We argue these are genuine philosophical problems about the practice of set-theory. We propound solutions, which crucially involve a renunciation of Connexion M. This breaks the dialectical situation of stalemate against the Skolemite skeptic. (shrink)

First published in 1945. In this work the author seeks to correct the misinterpretation and incorrect labelling of Shelley's thought. While not neglecting Shelley as a poet, this book focuses on his contributions made to the general movement of political and philosophical thought of his era and by so doing his relevance to contemporary issues. This title will be of interest to students of literature.

Over the past years, in books and journals (this journal included), N. Maxwell launched a ferocious attack on B. C. van Fraassen’s view of science called Constructive Empiricism (CE). This attack has been totally ignored. Must we conclude from this silence that no defence is possible and that a fortiori Maxwell has buried CE once and for all? Or is the attack too obviously flawed as not to merit exposure? A careful dissection of Maxwell’s reasoning will make it clear (...) that neither is the case. This dissection includes an analysis of Maxwell’s ‘aberrance–argument’ (omnipresent in his many writings) for the claim that science implicitly and permanently accepts a substantial, metaphysical thesis about the universe, which then paves the way for his own metaphysical-realist hierarchy-view of science. This aberrance-claim, which Maxwell directs against a widely shared and harmful ideology of science called ‘Standard Empiricism’, generally has been ignored too, for more than a quarter of a century. Our conclusions will be that (i) Maxwell’s attacks on CE can be beaten off, and (ii) his ‘aberrance–arguments’ do not establish what Maxwell believes they establish, but (iii) we can draw a number of valuable lessons from these attacks about the nature of science and of the libertarian nature of CE.

We inquire into the question whether the Aristotelean or classical \emph{ideal} of science has been realised by the Model Revolution, initiated at Stanford University during the 1950ies and spread all around the world of philosophy of science --- \emph{salute} P.\ Suppes. The guiding principle of the Model Revolution is: \emph{a scientific theory is a set of structures in the domain of discourse of axiomatic set-theory}, characterised by a set-theoretical predicate. We expound some critical reflections on the Model Revolution; the conclusions (...) will be that the philosophical problem of what a \emph{scientific theory} is has \emph{not} been solved yet --- \emph{pace} P.\ Suppes. While reflecting critically on the Model Revolution, we also explore a proposal of how to complete the Revolution and briefly address the intertwined subject of \emph{scientific representation}, which has come to occupy center stage in philosophy of science over the past decade.

There are thirteen essays in this collection. Sophisticated disquisitions on rather disparate topics, they contain a number of statements which are obscure to me and, I wager, to many readers, including metaphysicians. There is space here to note only a few of the several recurrent themes in Miller’s essays. First and foremost is the notion of the primacy of action. The affirmation of values, he says, is not a "matter of logic but of action," and "values become real only in (...) the deed"—values being prior to mere facts. Miller’s action-philosophy entails an exaltation of will over intellect. For instance, he says that "the pursuit of truth is itself a gesture of will." Another recurrent theme is the human inescapability of history—of time, process, transitoriness, corruptibility. What Miller calls "ahistorical sublimity" is purchased at too high a price-the price of a "radical impersonality" with an "apparent irrelevance to action and values." Miller’s view of freedom can be called intellectualist: "It is," he says, "in the ‘revision’ of truth that freedom is found." He refers not to "static" truth in the impersonal mode of physics but to dynamic truth in the mode of personal creativity. For "creative adventure," by action and experiment, he holds, is the mark of freedom. The entire "midworld" of artifacts, including arts, sciences, and languages, is the province of "responsible freedom." This whole area should be marked by "skepticism" as well as freedom, because skepticism is man’s best weapon against "absolutist pretensions," Miller persuasively argues. Furthermore, he stresses the point that there is no fact within our ken which is not linguistically expressible, so that "responsible humanism" is inconceivable without responsible use of language. The desideratum, as Miller says, is "controlled receptivity" regarding the employment of all linguistic signs and instruments. For "nature," the common object of all our knowledge, embraces not only facts but artifacts as well, including languages. He says that only "purposeful artifacts"-especially languages—put us in touch with actuality and history. History alone, he argues, leads into philosophy. "Ahistoric ideals," present everywhere in classical thought, stand in the way of this wedding of history and philosophy. A happy wedding for, according to Miller, there is no human knowledge that is not historical; everything human is dated. Miller is an action-philosopher because he is a history-philosopher. He contends that there is no freedom for us outside of history. He hails skepticism regarding "ahistoric ideals" as a kind of "negative absolutism." And he says that such skepticism is an "experience, not a theory," and that it makes "metaphysics of the transcendent" possible. He does not explain what that metaphysics is. Apparently, his "skepticism" is the awareness of the limited character of all philosophies. If so, it is, for Miller, our chief safeguard against the use of bloated language in the service of the ahistoric ideal.—J.F.A. (shrink)

The purpose of this book is to give a complete scientific notion of generation, and its implications for virtually all historical and philosophical disciplines. Generation, as a biological notion, is as old as mankind, but as a scientific notion, it is as recent as in the nineteenth century. The authors of that century, however, who have something to say about the matter—and Marias studies all of them—are incomplete, superficial, and even mistaken. The philosopher who developed a complete and definitive theory (...) of generations was José Ortega y Gasset, who derives it from his philosophy of radical reality or human life considered both individually and collectively. Briefly and very incompletely, a generation can be defined as constituted by those who are not only contemporary but also coetaneous, i.e., who have the same beliefs, problems and ideas and consequently contribute to the formation of the world in an equal or similar fashion; a generation lasts fifteen years, and in a given period of time there coexist three generations, the young, the mature, and the old. A chapter follows about the vicissitudes of the generations theme in our century, and again, in spite of Ortega’s comprehensive analysis, the authors who deal with the theme are found wanting. Finally the problems involved in the theory of generations, particularly the question concerning the empirical existence of generations and the way of determining their succession, are discussed and an attempt is made to solve them. Prescinding from whether Marias’ treatment of the concept of generations could well inaugurate a new movement in contemporary philosophy, his work will serve as a useful corrective to the many superficial treatments of the ‘generation gap’ that have been published.—F. A. (shrink)

In this paper thecanonicalmodal logics, a kind of complete modal logics introduced in K. Fine [4] and R. I. Goldblatt [5], will be characterized semantically using the concept of anultrafilter extension, an operation on frames inspired by the algebraic theory of modal logic. Theorem 8 of R. I. Goldblatt and S. K. Thomason [6] characterizing the modally definable Σ⊿-elementary classes of frames will follow as a corollary. A second corollary is Theorem 2 of [4] which states that any (...) complete modal logic defining a Σ⊿-elementary class of frames is canonical.The main tool in obtaining these results is the duality between modal algebras and general frames developed in R. I. Goldblatt [5]. The relevant notions and results from this theory will be stated in §2. The concept of a canonical modal logic is introduced and motivated in §3, which also contains the above-mentioned theorems. In §4, a kind of appendix to the preceding discussion, preservation of first-order sentences under ultrafilter extensions is discussed.The modal language to be considered here has an infinite supply of proposition letters, a propositional constant ⊥, the usual Boolean operators ¬, ∨, ∨, →, and ↔ —with ¬ and ∨ regarded as primitives—and the two unary modal operators ◇ and □ — ◇ being regarded as primitive. Modal formulas will be denoted by lower case Greek letters, sets of formulas by Greek capitals. (shrink)

Technological developments in the sphere of artificial intelligence (AI) inspire debates about the implications of autonomous weapon systems (AWS), which can select and engage targets without human intervention. While increasingly more systems which could qualify as AWS, such as loitering munitions, are reportedly used in armed conflicts, the global discussion about a system of governance and international legal norms on AWS at the United Nations Convention on Certain Conventional Weapons (UN CCW) has stalled. In this article we argue for the (...) necessity to adopt legal norms on the use and development of AWS. Without a framework for global regulation, state practices in using weapon systems with AI-based and autonomous features will continue to shape the norms of warfare and affect the level and quality of human control in the use of force. By examining the practices of China, Russia, and the United States in their pursuit of AWS-related technologies and participation at the UN CCW debate, we acknowledge that their differing approaches make it challenging for states parties to reach an agreement on regulation, especially in a forum based on consensus. Nevertheless, we argue that global governance on AWS is not impossible. It will depend on the extent to which an actor or group of actors would be ready to take the lead on an alternative process outside of the CCW, inspired by the direction of travel given by previous arms control and weapons ban initiatives.

In the context of discussions about the nature of ‘identical particles’ and the status of Leibniz’s Principle of the Identity of Indiscernibles in Quantum Mechanics, a novel kind of physical discernibility has recently been proposed, which we call witness-discernibility. We inquire into how witness-discernibility relates to known kinds of discernibility. Our conclusion will be that for a wide variety of cases, including the intended quantum-mechanical ones, witness-discernibility collapses extensionally to absolute discernibility, that is, to discernibility by properties.

When classes of structures are not first-order definable, we might still try to find a nice description. There are two common ways for doing this. One is to expand the language, leading to notions of pseudo-elementary classes, and the other is to allow infinite conjuncts and disjuncts. In this paper we examine the intersection. Namely, we address the question: Which classes of structures are both pseudo-elementary and ${\mathcal {L}}_{\omega _1, \omega }$ -elementary? We find that these are exactly the classes (...) that can be defined by an infinitary formula that has no infinitary disjunctions. (shrink)

The novel coronavirus has not only brought along disruptions to daily socio-economic activities, but sickness and deaths due to its high contagion. With no widely acceptable pharmaceutical cure, the best form of prevention may be precautionary measures which will guide against infections and curb the spread of the disease. This study explored the relationship between COVID-19 knowledge, risk perception, and precautionary behavior among Nigerians. The study also sought to determine whether this relationship differed for men and women. A web-based (...) cross-sectional design approach was used to recruit 1,554 participants from all geopolitical zones in Nigeria, through social media platforms using a snowball sampling technique. Participants responded to web-based survey forms comprising demographic questions and adapted versions of the Ebola knowledge scale, SARS risk perception scale, and precautionary behavior scale. Moderated mediation analysis of the data showed that risk perception mediated the association between COVID-19 knowledge and precautionary behavior and this indirect effect was in turn moderated by gender. Results indicate that having adequate knowledge of COVID-19 was linked to higher involvement in precautionary behavior through risk perception for females but not for males. It was also noted that awareness campaigns and psychological intervention strategies on COVID-19 related activities may be particularly important for males more than females. Drawing from the health belief model, we recommend that COVID-19 awareness campaigns should target raising more awareness of the risks associated with the infection to make individuals engage more in precautionary behaviors.

Inducing religious thoughts increases prosocial behavior among strangers in anonymous contexts. These effects can be explained both by behavioral priming processes as well as by reputational mechanisms. We examine whether belief in moralizing supernatural agents supplies a case for what McKay & Dennett (M&D) call evolved misbelief, concluding that they might be more persuasively seen as an example of culturally evolved misbelief.

The temporal structure of behavior contains a rich source of information about its dynamic organization, origins, and development. Today, advances in sensing and data storage allow researchers to collect multiple dimensions of behavioral data at a fine temporal scale both in and out of the laboratory, leading to the curation of massive multimodal corpora of behavior. However, along with these new opportunities come new challenges. Theories are often underspecified as to the exact nature of these unfolding interactions, and psychologists have (...) limited ready-to-use methods and training for quantifying structures and patterns in behavioral time series. In this paper, we will introduce four techniques to interpret and analyze high-density multi-modal behavior data, namely, to: (1) visualize the raw time series, (2) describe the overall distributional structure of temporal events (Burstiness calculation), (3) characterize the nonlinear dynamics over multiple timescales with Chromatic and Anisotropic Cross-Recurrence Quantification Analysis (CRQA), (4) and quantify the directional relations among a set of interdependent multimodal behavioral variables with Granger Causality. Each technique is introduced in a module with conceptual background, sample data drawn from empirical studies and ready-to-use Matlab scripts. The code modules showcase each technique’s application with detailed documentation to allow more advanced users to adapt them to their own datasets. Additionally, to make our modules more accessible to beginner programmers, we provide a “Programming Basics” module that introduces common functions for working with behavioral timeseries data in Matlab. Together, the materials provide a practical introduction to a range of analyses that psychologists can use to discover temporal structure in high-density behavioral data. (shrink)

The latest trend in abortion restrictions in the United States targets a woman's reasons for terminating a pregnancy. Fourteen states have attempted to enact laws prohibiting abortion on the basis of fetal sex, race, and/or genetic anomaly. These laws are different from regulations tied to a government interest in protecting women's health. Laws that restrict reasons implicate a different set of government interests to be weighed against a woman's constitutional right first recognized in Roe v. Wade. These laws also seek (...) to reframe the nature of the right asserted by the woman. To date, the Supreme Court has declined to address the constitutionality of laws that restrict reasons, and the Court's most recent abortion decisions provide little guidance. It is possible that a conservative majority of the Supreme Court would uphold a law that prohibits reasons for having an abortion that appear discriminatory. But such laws would be difficult to enforce and therefore may be relegated to policy statements rejecting discriminatory norms as opposed to being effective means of restricting access to abortion.

An increasing number of jurisdictions allow individuals to obtain medication prescribed by their physicians for medical assistance in dying (MAID). But discussion of whether (and to what extent) individuals have the right to use the health care system to control the time and manner of their death is not limited to MAID. The right also exists in other contexts, such as directing the withdrawal of life‐sustaining treatments. Palliative (or terminal) sedation involves medications to render a patient unconscious, coupled with either (...) the withdrawal of artificial nutrition and hydration or their not being administered at all. In high‐enough doses, these medications may further suppress already‐weakened cardiopulmonary function even if there is no intent to hasten death. When teaching about these topics, I challenge students to consider whether there are meaningful differences between practices like euthanasia, MAID, aggressive use of morphine, terminal sedation, or the withdrawal of ventilator support. Whether their differences are morally, ethically, or legally meaningful can be difficult to tease out. After recently watching a loved one, whom I call “Stephan,” direct the time and manner of his death within hospice care in a state that does not allow MAID, I am less inclined than ever to believe that the differences are meaningful in a way the law should recognize.

John McMillan's article raises numerous important points about the ethics of surgical castration of sex offenders.1 In this commentary, we focus solely on and argue against the claim that the offer of release from detention conditional upon surgical castration is a coercive offer that compromises the validity of the offender's consent. We take no view on the question as to whether castration for sex offenders is ethically permissible. But, we reject the claim that it is ethically permissible only if competing (...) ethical considerations outweigh worries about coercion. For in the situation described, the proposal is not coercive at all.McMillan states that if offenders agree to castration because they fear long-term detention, then ‘it seems, intuitively, as if agreeing to be castrated under these conditions makes the decision coerced in some way.’1 He adds that if castration is ‘the only way that they will be released back into the community, the status of this decision as a genuine expression of their autonomy is questionable.’1 In defence of his claim, he uses two analogies that he borrows from Joel Feinberg. First, if a governor offers to commute a death sentence if the prisoner agrees to participate in a medical experiment, then ‘it's clear that the governor is coercing the prisoner.’1 Second, if a millionaire offers to give a woman $1 000 000 ….

Lifestyle diseases constitute an increasing proportion of health problems and this trend is likely to continue. A better understanding of the responsibility argument is important for the assessment of policies aimed at meeting this challenge.

In this article the main arguments for and the traditional arguments against the use of individual responsibility as a criterion for (...) the distribution of scarce health resources will be briefly outlined. It is argued that one of the most prominent contemporary normative traditions, liberal egalitarianism, presents a way of holding individuals accountable for their choices that avoids most of the problems pointed out by the critics. The aim of the article is to propose a plausible interpretation of liberal egalitarianism with respect to responsibility and health care and assess it against reasonable counter-arguments. (shrink)

As a patient approaches death, family members often are asked about their loved one’s preferences regarding treatment at the end of life. Advance care directives may provide information for families and surrogate decision makers; however, less than one-third of Americans have completed such documents. As the U.S. population continues to age, many surrogate decision makers likely will rely on other means to discern or interpret a loved one’s preferences. While many surrogates indicate that they have some knowledge of their (...) loved one’s preferences, how surrogates obtain such knowledge is not well understood. Additionally, although research indicates that the emotional burden of end-of-life decision making is diminished when surrogates have knowledge that a loved one’s preferences are honored, it remains unclear how surrogates come to know these preferences were carried out. The current study examined the ways that next of kin knew veterans’ end-of-life preferences, and their ways of knowing whether those preferences were honored in Veteran Affairs Medical Center inpatient settings.

This paper focuses on the normative analysis—in the sense of the classic decision-theoretic formulation—of decision problems that arise in connection with forensic expert reporting. We distinguish this analytical account from other common types of decision analyses, such as descriptive approaches. While decision theory is, since several decades, an extensively discussed topic in legal literature, its use in forensic science is more recent, and with an emphasis on goals such as the analysis of the logical structure of forensic expert conclusions regarding, (...) for example, propositions of common source of evidential and known materials. Typical examples are so-called identification decisions, especially categorical conclusions according to which fingermarks come from a particular a person of interest. We will present and compare ways of stating forensic identification decisions in decision-theoretic terms and explain their underlying rationale. In particular, we will emphasize the importance of viewing this analysis as normative in the sense of providing a reflective rather than a prescriptive reference point against which people in charge of forensic identification decisions may compare their otherwise intuitive and informal reasoning, before acting. Normative decision analysis in forensic science thus provides a vector through which current practice can be articulated, scrutinized and rethought. (shrink)

Understanding the ethical attitudes and concerns of future business leaders has been the focus of increasing research attention. Largely, this is due to the influence of such perspectives, as it is these presently held ideologies that ultimately translate into the actions and behaviors of the forthcoming workforce. This research examines how such business-related ethicality perspectives have evolved by administering a nationwide survey that builds on two Journal of Business Ethics studies, Beltramini et al. (J Bus Ethics 3:195–200, 1984 ) and (...) Peterson et al. (J Bus Ethics 10:733–738, 1991 ), resulting in the latest segment of a three-decade historical perspective of ethical concerns. Our findings indicate fundamental shifts regarding the nature of concerns, and provide a number of practical and theoretical contributions to the ethics literature, bringing us one step closer to more comprehensively understanding, and ultimately enhancing ethical practices in business.

In section I the notions of logical and inductive probability will be discussed as well as two explicanda, viz. degree of confirmation, the base for inductive probability, and degree of evidential support, Popper's favourite explicandum.

Free will can be understood as a novel form of action control that evolved to meet the escalating demands of human social life, including moral action and pursuit of enlightened self-interest in a cultural context. That understanding is conducive to scientific research, which is reviewed here in support of four hypotheses. First, laypersons tend to believe in free will. Second, that belief has behavioral consequences, including increases in socially and culturally desirable acts. Third, laypersons can reliably distinguish free (...) actions from less free ones. Fourth, actions judged as free emerge from a distinctive set of inner processes, all of which share a common psychological and physiological signature. These inner processes include self-control, rational choice, planning, and initiative. (shrink)

Neptunus et Apollo dicuntur Troiam muro cinxisse; his rex Laomedon uouit quod regno suo pecoris eo anno natum esset immolaturum. id uotum auaritia fefellit. alii dicunt †parum eum promisisse. The story that Neptune and Apollo together built the walls of Troy for Laomedon is well known from Homer. At the end of their year's service the perfidious king refused to pay the agreed wages. Ovid tells the familiar story in one of his transitional sections in the Metamorphoses. Hyginus' account poses (...) the textual problem indicated above. H. I. Rose comments on ‘parum’ as follows: ‘procul dubio corruptum hoc neque arridet Schmidtii coniectura promsisse. fuitne partum equarum? hoc enim plerumque narratur, equos quos a Ioue accepisset promisisse Laomedontem mercedis nomine…sed Herculi; quod facile ad deos mercennarios transferri potuit; atque non equos sed equas fuisse tradit Apollod. II, 104’. Rose rightly rejects Schmidt's emendation ‘promsisse’. ‘Promisisse’ has every sign of soundness and the difficulty lies, as Rose sees, with ‘parum’. Rose's own conjecture ‘partum equarum’, however, will not do. Apart from the oddity of the expression, one would need a good deal more persuasion than Rose offers to accept that the well-known promise of Zeus' horses which Laomedon made to Hercules was transferred from Hercules to Neptune and Apollo. There is no suggestion anywhere in the sources that Laomedon promised to give Neptune and Apollo the famous horses as payment for building the walls. (shrink)

Adolescence methamphetamine use is an issue of considerable concern due to its correlation with later delinquency, divorce, unemployment and health problems.

The model is then fitted to data on methamphetamine users less than 20 years old reporting methamphetamine as their primary substance of abuse in the treatment centres of Cape Town and parameter values that give the best fit are chosen. Results show that the proportion of methamphetamine users less than 20 years old reporting methamphetamine as their primary substance of abuse will continue to decrease in Cape Town of South Africa. The results suggest that intervention programs targeted at reducing adolescence methamphetamine abuse, are positively impacting methamphetamine abuse. (shrink)

In the Nicomachean Ethics, Aristotle appears to use an elegant short argument to attack Plato's doctrine of the good, which argument equally appears to attack Aristotle's own doctrine of the good. I consider these two questions: First: Why does Aristotle reverse the judgment of Socrates/Plato on the issue: Which is better - things that are good in themselves, or things that are both good in themselves and good for their consequences? Second: Why does Aristotle attack Plato's doctrine that the Form (...) of the Good is the chief good, with an argument that appears to threaten his own view that eudaimonia is the chief good? I think the answers to these two questions are related. The elegant short argument in question I call "Aristotle's Fast Argument." After apologizing for criticizing views held by friends of his, Aristotle deploys the Fast Argument as a clincher to cap off his refutation of Plato's view that the Form of the Good is the chief good: "And one might ask the question, what in the world they mean by 'a thing itself', if in man himself and in a particular man the account of man is one and the same. For in so far as they are men, they will in no respect differ; and if this is so, neither will there be a difference in so far as they are good. But again it will not be good any the more for being eternal, since that which lasts long is no whiter than that which perishes in a day.". I explore this sketchily presented Fast Argument. I consider why Aristotle may think it is valid and why he does not seem to realize that, on readings that make it effective against Plato's view, his Fast Argument also seems to apply to his own view that eudaimonia is the chief good. This is what I will call "Aristotle's Dilemma." If the Fast Argument is interpreted too narrowly, its point about the whiteness of a white thing being independent of its duration will not apply to the goodness of the Form of the Good. If it is interpreted broadly enough to undermine the claim of the Form of the Good to be the chief good, it will equally undermine that claim for eudaimonia. Finally, I discuss some of the things Plato and Aristotle say about the chief good, and comparable things Immanuel Kant says about the good will. I draw some speculative conclusions that focus on the importance for Aristotle of the goodness of the chief good not being at risk. (shrink)

So far, the most prominent measure for actual truthlikeness, i.e. the likeness of a theory to the actual truth, is Ilkka Niiniluoto’s minsum definition, which is purely based on distances. A competing definition is the average distance measure proposed by Pavel Tichy and Graham Oddie. We will define three related, distance and size based, measures for actual truthlikeness and compare them with the two well-known options. However, we will start, Sect. 2, from a trio of such measures for (...) nomic truthlikeness. The nomic truth, or the true theory, here refers to what is nomically, e.g. physically, possible. In a nomic (and factual) context there are two basic kinds of theories, viz. either based on an exclusion claim or on an inclusion claim. Two-sided theories combine these claims, with the maximal claim as extreme special case. We will base truthlikeness measures for exclusion, inclusion, two-sided, and hence maximal, nomic theories on two similarity measures, one in terms of distances between conceptual possibilities and the other in terms of sizes of sets of such possibilities. In Sect. 3 we will treat actual truthlikeness as extreme special case of nomic truthlikeness, viz. assuming that there is just one nomic possibility, the actual one. Next we will compare the resulting measures mutually and with the above mentioned measures of Niiniluoto and Tichy & Oddie. Finally, in Sect. 4, we will sum up the results and explore five questions for further research. (shrink)

Muhammadiyah and NU are two well-known socio-religious organizations in the world over the years. In spite of the fact that both organizations are characterized as religious social movement, each of them has their individual creativity, which is called al-thaqafat in their motions. This study aims to identify the organization of Muhammadiyah-NU as a religious heritage,which affects other religious organizations both in Indonesia and other countries. This research employed a qualitative approach by using historical method to obtain the actual reality. For (...) data collection, literature reviews,documentation and interviews were also conducted to gather empiric facts.The researchers interviewed public figures of the organizations. Al-thaqafat becomes part of elements rather than cultivated culture, which is understood as habitual patterns of human creativity, including a religious organization. Both organizations are the result of an al-thaqafat religious creativity created by each founder and can be pursued into the world monumental heritage. Without denying, the existence of al-thaqafat creativity will continue to enlighten the world civilization. Therefore, Muhammadiyah and NU have been doing and keeping continuing al-thaqafat creativity enlightenment through their charitable organizations and institutions. The result is profoundly proven so that they have been in an existence more than a century. (shrink)

The visual world of animals is highly diverse and often very different from the world that we humans take for granted. This book provides an extensive review of the latest behavioral and neurobiological research on animal vision, highlighting fascinating species similarities and differences in visual processing. It contains 26 chapters written by world-leading experts about a variety of species including: honeybees, spiders, fish, birds, and primates. The chapters are divided into six sections: Perceptual grouping and segmentation, Object perception and object (...) recognition, Motion perception, Visual attention, Different dimensions of visual perception, and Evolution of the visual system. An exhaustive work in range and depth, How Animals See the World will be a valuable resource for advanced students and researchers in areas of cognitive psychology, perception and cognitive neuroscience, as well as researchers in the visual sciences.

As Professor Dov Fox points out in his essay, reference to “potential life” in American abortion jurisprudence is both indeterminate and underspecified. This commentary highlights that use of the phrase “potential life” by courts also obscures the fact that a position has been taken that biological life is not the equivalent of legal personhood. Worse, the position has been imposed on those who do not share it without offering reasons to justify its imposition in terms that those who oppose it (...) can reasonably be expected to endorse.

In section I the notions of logical and inductive probability will be discussed as well as two explicanda, viz. degree of confirmation, the base for inductive probability, and degree of evidential support, Popper's favourite explicandum. In section II it will be argued that Popper's paradox of ideal evidence is no paradox at all; however, it will also be shown that Popper's way out has its own merits.

We formulate a model of EPR experiments by including variables determining whether a photon will be detected or not. The resulting deterministic model satisfies Bell's original inequality even though it can agree exactly with the quantum mechanical predictions for the performed experiments. It violates variations of the inequality used in the interpretation of the experiments and deduced with the help of additional assumptions.

Li. 263 and 264 have been much vexed, and a string of conjectures will be found in Wecklein's appendix. All of them produce roughly the same meaning–‘it is useless to enquire into the future, which is bound to be disastrous.’.

Recall that a group G has finitely satisfiable generics (fsg) or definable f-generics (dfg) if there is a global type p on G and a small model $M_0$ such that every left translate of p is finitely satisfiable in $M_0$ or definable over $M_0$, respectively. We show that any abelian group definable in a p-adically closed field is an extension of a definably compact fsg definable group by a dfg definable group. We discuss an approach which might prove a similar (...) statement for interpretable abelian groups. In the case where G is an abelian group definable in the standard model $\mathbb {Q}_p$, we show that $G^0 = G^{00}$, and that G is an open subgroup of an algebraic group, up to finite factors. This latter result can be seen as a rough classification of abelian definable groups in $\mathbb {Q}_p$. (shrink)

THE surviving century of epigrams by this tedious writer was edited with a commentary by J. Geffcken in 1896, and they were included in A. Veniero's Poeti de l'Antol. Pal. and A. Olivieri's Epigrammatisti Gr. d. Magna Grecia , but the inquirer who is not content with Geffcken's explanations or with his frequent silences will rarely find satisfaction in Veniero, and Olivieri's comments are almost exclusively translated from Geffcken. I have not a great deal to offer by way of (...) supplement, but as a preliminary it may be worth while to consider the five epigrams which have been held to throw light on the poet's date, and first A.P. 6. 334, on which the authorities rely with varying degrees of confidence for placing his birth in or before 315 B.C.

Some day, it may be, a betterGreek scholar and more skilful emendator than I will summon to hisaid from among scientists familiar with the Levant a botanist, aherbalist, a herpetologist, and an entomologist, empanel forconsultations a small body of medical men who have practised in theNear East, and produce an annotated text and translation of Nicander;and when this has been done it will be possible to read him, notindeed with pleasure, but with a good deal less labour and (...) vexationthan attend the process at present. Meanwhile, those whose dutyobliges them to struggle through the Theriaca andAlexipharmaca with the aids now available stand in no need ofthe injunction not to forget him which the author has appended tothose two poems.

As in Marx's and Lenin's time, bourgeois critics of Marxism are accusing Marxists of denying ethics in principle. Some of them say that Marxist economic theory entirely rules out any element of free choice of actions and ethical judgment. Others say that Marx's economic analysis includes a moral indictment of capitalism as an unjust society, but that this means no more than that the ethical element in Marxism is entirely pushed aside by economic analysis and plays no independent role. In (...) the opinion of these critics, Marxism merely reduces such questions as what man should do, and what the ethical norms of his life are, to acceptance of the justice and moral rightness of whatever emerges in history as economic necessity. In other words, Marxism allegedly "makes a virtue of necessity" where ethics is concerned, and demands of human beings nothing more than adaptation to what is or to what will be. In either case, according to that interpretation of Marxism, people must accept without qualification that which corresponds to historical necessity. Free choice, reason, and human conscience can play no role. (shrink)

In our contribution we will observe phenomenal architecture of a mind and operational architectonics of the brain and will show their intimate connectedness within a single integrated metastable continuum. The notion of operation of different complexity is the fundamental and central one in bridging the gap between brain and mind: it is precisely by means of this notion that it is possible to identify what at the same time belongs to the phenomenal conscious level and to the neurophysiological (...) level of brain activity organization, and what mediates between them. Implications for linguistic semantics, self-organized distributed computing algorithms, artificial machine consciousness, and diagnosis of dynamic brain diseases will be discussed briefly. (shrink)

Salutary reading for all philosophers, and not only for inductive logicians, philosophers of science and law, this important book presents an elaborate theory of inductive reasoning whose substantive features are as strikingly original as the approach is rare. First, the theory is based on concrete, real, actual, and significant instances of inductive reasoning, e.g., Karl von Frisch’s work on bees; that is, though its aim is genuinely theoretical in the sense that it engages in the proper amounts of idealization, abstraction, (...) systematization, precision, and rigor, it never loses sight of the fact that "theories in the philosophy of science, like theories in science itself, have to face up to the challenge of appropriately accredited experience within their appointed domains". Second, a central subject matter being analyzed is legal reasoning, that is, the types of proofs and arguments used by juries, judges, and lawyers in the Anglo-American system of jurisprudence, where criminal charges have to be proved beyond reasonable doubt and civil cases have to be argued on the balance of probability. Thus, in effect, Cohen’s synthesis of juridical and of scientific reasoning is an admirable example of the bridging of two "cultures." Third, and most importantly, the concept of "inductive probability," in terms of which Cohen makes sense out of his subject matter, is incommensurable with that of "mathematical probability," namely the classical calculus of chance according to which probability is measurable, additive, transitive, and obeys a multiplicational principle for conjunction and a complementational one for negation. This is not to say that "inductive probability" is a hazy, mysterious, or unstructured concept, and Cohen goes to great lengths to show that it is ordinal, modal, and formally analyzable; what it does mean is that essential types of reasoning in science and in law involve probable inferences whose probabilities are nonquantitative. Hence, though Cohen does not stress the qualitative nature of inductive probability, his book will be welcome by those who conceive of philosophy as scientia qualitatum. Specific conclusions reached by Cohen are that, in general, probability may be conceived as degree of provability, that differences in proof-rules generate different special cases of probability, that inductive probability may be viewed as the special case where the proof-rules are incomplete, that inductive probability is to inductive support as deducibility is to logical truth, and that some recent epistemological scepticism may be refuted by Cohen’s inductive logic. Finally, he sees himself in the British inductivist tradition, interpreting his predecessors as groping toward a logic of inductive support and probability rather than a methodology of discovery: from Bacon he develops the notion of eliminative induction but rejects that of induction by enumeration; Mill’s canons are analyzed as special cases of Cohen’s own "method of relevant variables," except for the method of residues, which is rejected as invalid ; he takes his critique of mathematical probability as a vindication of Hume’s thesis that "probability or reasoning from conjecture may be divided into two kinds, viz., that which is founded on chance and that which arises from causes" ; Whewell’s consilience of induction is justified ; and from Keynes, he develops the notion of the "weight" of evidence but rejects his mathematicist approach.—M.
