It is human nature to try to recognize patterns and to make sense of that which we observe. Unfortunately, our intuition is often wrong, and so there is a need to impose some objectivity on the methods by which observations are converted into knowledge. One definition of biostatistics could be precisely this, the rigorous and objective conversion of medical and/or biological observations into knowledge. Both consumers of biostatistical principles and biostatisticians themselves vary in the extent to which they recognize the (...) need to continue the improvement. Some may not recognize the need for (some or all of) the methods that have already been developed; others may accept these as they find them completely sufficient; still others recognize both the value and the shortcomings of these methods, and seek to develop even better methods to ensure that future medical conclusions are less subject to biases than current ones are.

J. L. Schellenberg’s Divine Hiddenness and Human Reason claims that the existence of reflective persons who long to solve the problem of God’s existencebut cannot do so constitutes an evil rendering God’s existence improbable. In this essay, I present Schellenberg’s argument and argue that the kind of reasonable nonbelief Schellenberg needs for his argument to succeed is unlikely to exist. Since Schellenberg’s argument is an inductive-style version of the problem of evil, the empirical improbability of the premise I challenge renders (...) the conclusions derived from it empirically improbable as well.

We comment on the proposition “that lower temperatures and especially greater seasonal variation in temperature call for individuals and societies to adopt … a greater degree of self-control” (Van Lange et al., sect. 3, para. 4) for which we cannot find empirical support in a large data set with data-driven analyses. After providing greater nuance in our theoretical review, we suggest that Van Lange et al. revisit their model with an eye toward the social determinants of self-control.

The pacemaker-accumulator model provides a framework in which the results of different duration estimation tasks are commonly accounted for. Nevertheless, the model remains abstract and it does not provide proper explanations nor predictions for duration estimations in various experimental set-ups. This paper aims to address these shortcomings by explicating an experiential pacemaker-accumulator model that supplements the standard pacemaker-accumulator model with two claims. Both of them concern the role that experiences play in duration estimation tasks and are also partly supported (...) by studies not directly related to duration estimation. First, the internal responses based on which the switch between the pacemaker and the accumulator operates are the same as the neural processes that realize conscious access to experiences. Second, the processes that realize the experiences of stimuli realize the function of the pacemaker. By supplementing the standard pacemaker-accumulator model with these claims, the model affords proper explanations for the systematic errors and empirically testable predictions in duration estimations tasks. One likely consequence of the model is that the experience of duration and the duration of experience can differ. (shrink)

Although the genetics of dorsal‐ventral polarity which leads to mesoderm formation in Drosophila are understood in considerable detail, subsequent molecular mechanisms involved in patterning the mesoderm primordium into individual mesodermal subtypes are poorly understood. Two papers published recently (1,2) suggest strongly that an inductive signal from dorsal ectoderm is involved in subdividing the underlying mesoderm, and present evidence that one of the signalling factors is Decapentaplegic (Dpp), a member of the bone morphogenetic protein subgroup of the Transforming Growth Factor‐β (TGF‐β) (...) super family of proteins.

We investigate logical consequence in temporal logics in terms of logical consecutions. i.e., inference rules. First, we discuss the question: what does it mean for a logical consecution to be 'correct' in a propositional logic. We consider both valid and admissible consecutions in linear temporal logics and discuss the distinction between these two notions. The linear temporal logic LDTL, consisting of all formulas valid in the frame 〈L, ≤, ≥〉 of all integer numbers, is the prime object of our (...) investigation. We describe consecutions admissible LDTL in a semantic way—via consecutions valid in special temporal Kripke/Hintikka models. Then we state that any temporal inference rule has a reduced normal form which is given in terms of uniform formulas of temporal degree 1. Using these facts and enhanced semantic techniques we construct an algorithm, which recognizes consecutions admissible in LDTL. Also, we note that using the same technique it follows that the linear temporal logic L (N) of all natural numbers is also decidable w.r.t. inference rules. So, we prove that both logics LDTL and L (N) are decidable w.r.t. admissible consecutions. In particular, as a consequence, they both are decidable (Known fact), and the given deciding algorithms are explicit. (shrink)

In philosophical logic necessity is usually conceived as a sentential operator rather than as a predicate. An intensional sentential operator does not allow one to express quantified statements such as 'There are necessary a posteriori propositions' or 'All laws of physics are necessary' in first-order logic in a straightforward way, while they are readily formalized if necessity is formalized by a predicate. Replacing the operator conception of necessity by the predicate conception, however, causes various problems and forces one to (...) reject many philosophical accounts involving necessity that are based on the use of operator modal logic. We argue that the expressive power of the predicate account can be restored if a truth predicate is added to the language of first-order modal logic, because the predicate 'is necessary' can then be replaced by 'is necessarily true'. We prove a result showing that this substitution is technically feasible. To this end we provide partial possible-worlds semantics for the language with a predicate of necessity and perform the reduction of necessities to necessary truths. The technique applies also to many other intensional notions that have been analysed by means of modal operators. (shrink)

“Terminal sedation” refers to the use of sedation as palliation in dying patients with a terminal diagnosis. Although terminal sedation has received widespread legal and ethical justification, the practice remains ethically contentious, particularly as some hold that it foreseeably hastens death. It has been proposed that empirical studies show that terminal sedation does not hasten death, or that even if it may hasten death it does not do so in a foreseeable way. Nonetheless, it is clear that providing (...) terminal sedation in combination with the withholding or withdrawing of life-prolonging treatments such as fluid and nutrition can foreseeably hasten death significantly—what is here called early terminal sedation . There are ethical justifications for the use of sedation in palliative care and thus it would seem that ETS is an ethically and legally acceptable practice. However, what emerges from the literature is the repeated assertion that terminal sedation must be restricted to use in imminently dying patients—the “imminence condition”—and that therefore ETS is unacceptable. This restriction has taken on greater significance with the trend of palliative care to include the care of patients who are not imminently dying. This paper proposes to show that although there is widespread intuitive support for the imminence condition, it does not follow from the justifications for sedation as palliation, and that explicit arguments for the imminence condition are needed.

A stable classification of practical principles into mutually exclusive types is foundational to Kant’s moral theory. Yet, other than a few brief hints on the distinction between maxims and laws, he does not provide any elaborate discussion on the classification and the types of practical principles in his works. This has led Onora O’Neill and Lewis Beck to reinterpret Kant’s classification of practical principles in a way that would clarify the conceptual connection between maxims and laws. In this paper (...) I argue that the revised interpretations of O’Neill and Beck stem from a mistaken reading of the fundamental basis of the classification of practical principles. To show this, I first argue that Kant distinguishes between maxims and laws on the bases of validity and reality. I then argue that although a practical principle necessarily has the feature of validity, its reality in actually moving the agents to action sufficiently makes a principle a practical principle. If this is so, I argue that the classification of practical principles must be based on the extent to which they are effective in human agents. Such a classification yields us three exhaustive and mutually exclusive types namely, “maxims that are not potential laws”, “maxims that are potential laws” and “laws that are not maxims”. (shrink)

When it comes to injustice, especially racial injustice, rage isn't just an acceptable response-it's crucial in order to fuel the fight for change. Anger has a bad reputation. Many people think that it is counterproductive, distracting, and destructive. It is a negative emotion, many believe, because it can lead so quickly to violence or an overwhelming fury. And coming from people of color, it takes on connotations that are even more sinister, stirring up stereotypes, making white people fear what an (...) angry other might be capable of doing, when angry, and leading them to turn to hatred or violence in turn, to squelch an anger that might upset the racial status quo. According to philosopher Myisha Cherry, anger does not deserve its bad reputation. It is powerful, but its power can be a force for good. And not only is it something we don't have to discourage, it's something we ought to cultivate actively. People fear anger because they paint it in broad strokes, but we can't dismiss all anger, especially not now. There is a form of anger that in fact is crucial in the anti-racist struggle today. This anti-racist anger, what Cherry calls Lordean rage, can use its mighty force to challenge racism: it aims for change, motivates productive action, builds resistance, and is informed by an inclusive and liberating perspective. People can, and should, harness Lordean rage and tap into its unique anti-racist potential. We should not suppress it or seek to replace it with friendly emotions. If we want to effect change, and take down racist structures and systems, we must manage it in the sense of cultivating it, and keeping it focused and strong. Cherry makes her argument for anti-racist anger by putting Aristotle in conversation with Audre Lorde, and James Baldwin in conversation with Joseph Butler. The Case for Rage not only uses the tools of philosophy to articulate its arguments, but it sharpens them with the help of social psychology and history. The book is philosophically rich and yet highly accessible beyond philosophical spheres, issuing an urgent call to all politically and socially engaged readers looking for new, deeply effective tools for changing the world. Its message will resonate with the enraged and those witnessing such anger, wondering whether it can help or harm. Above all, this book is a resource for the activist coming to grips with a seemingly everyday emotion that she may feel rising up within her and not know what to do with. It shows how to make sure anger doesn't go to waste, but instead leads to lasting, long-awaited change. (shrink)

The primary function of Sanskrit kāvya was always to please the readers. Literary theoreticians like Abhinavagupta often considered esthetic experience as a supramundane (alaukika) experience where the readers transcend their mundane attachments. Viśvanatha compared it to the experience of knowing brahman, the ultimate truth. But this does not mean that Sanskrit kāvya was devoid of any pragmatic concerns and was exclusively concerned with esthetic bliss. This paper examines how the purvamīmāmsā theory of bhāvanā was effectively employed by Sanskrit literary (...) theoreticians in Early India to make the readers of Sanskrit kāvya self-fashion themselves according to the existing notions about the practice of puruṣārtha-s. This mechanism, which literary critics from Kuntaka onwards explicitly mentioned, capacitated kāvya with a symbolic power to influence the worldview of readers and to make them conform to the existing dharmavidhi (legal injunction with respect to the four aims of human life). How did the idea of bhāvanā function in the composition of Sanskrit kāvya to self-fashion the readers? And how did the writers of kāvya precondition their texts so that readers should self-fashion themselves? The present paper explores these two crucial questions which shed light on the pragmatic use of Sanskrit kāvya. (shrink)

The issue of why God, the Trinity and Christ in Christianity can be called "beautiful" has been muddled in literature on theological aesthetics. John Duns Scotus’s detailed discussion of relations within the Trinity helps resolve this issue. The Trinity can be called "beautiful" in at least three senses, depending on whether one considers Trinitarian relations at all, whether one looks at the relation of equality, or whether one analyzes relations of origin.

Logic today is a ramified discipline existing on many levels. It is actively pursued by philosophers, mathemeticians, and computer specialists. The reason is that it is widely employed to solve a number of problems both in the theory of knowledge and in mathematics and computer science. But the broad spectrum of application of contemporary logic does not change the fact that its basic content has the nature of philosophical methodology. In contemporary logic it is the forms of thought and (...) the methods of scientific cognition, the modes of organization of scientific knowledge, and the procedures for the introduction of various concepts, abstractions, and idealizations that are studied. This places logic in intimate contact with epistemology and methodology. The distinctiveness of the approach taken by formal logic to this particular subject consists simply of its studying all these procedures pertaining to concrete cognition through the use of special formal languages, of algebraic, topological, and other exact techniques.

Cultural evolutionary theories define prestige as social rank that is freely conferred on individuals possessing superior knowledge or skill, in order to gain opportunities to learn from such individuals. Consequently, information provided by prestigious individuals should be more memorable, and hence more likely to be culturally transmitted, than information from non-prestigious sources, particularly for novel, controversial arguments about which preexisting opinions are absent or weak. It has also been argued that this effect extends beyond the prestigious individual’s relevant domain of (...) expertise. We tested whether the prestige and relevance of the sources of novel, controversial arguments affected the transmission of those arguments, independently of their content. In a four-generation linear transmission chain experiment, British participants recruited online read two conflicting arguments in favour of or against the replacement of textbooks by computer tablets in schools. Each of the two conflicting arguments was associated with one of three sources with different levels of prestige and relevance. Participants recalled the pro-tablets and anti-tablets arguments associated with each source and their recall was then passed to the next participant within their chain. Contrary to our predictions, we did not find a reliable effect of either the prestige or relevance of the sources of information on transmission fidelity. We discuss whether the lack of a reliable effect of prestige on recall might be a consequence of differences between how prestige operates in this experiment and in everyday life. (shrink)

Public good contributions have been an interest for many experimental economists, since evidence has shown that people do not always behave rationally and inefficient equilibria are not always realized. This research compares a public good game run in both China and Germany with three treatments in which the social distance factor varies. The outcome shows that under a condition of high social distance, Chinese and German behavior differs with German subjects contributing more to the public good. As social distance decreases, (...) both samples converge to insignificantly different averages of contribution. It is also found that people’s contribution is positively correlated with their guess and level of anonymity: the more their identity is exposed, the more they give and the more they believe the other is giving.

The game theoretical approach to R&D cooperation does not investigate the role of trust in the initiation and success of R&D cooperation: it either assumes that firms are non-opportunists or that the R&D cooperation is supported by an incentive mechanism that eliminates opportunism. In contrast, the present paper focuses on these issues by introducing incomplete information and two types of firms: opportunist and non-opportunist. Defining trust as the belief of each firm that its potential collaborator will respect the contract, (...) it identifies the trust conditions under which firms initiate R&D alliances and contribute to their success. The higher the spillovers, the higher the level of trust required to initiate R&D cooperation for non-opportunists, while the inverse holds for opportunists. (shrink)

Over the last twenty years, literary theory has become peculiarly fascinated with what language cannot do, and with the impossibility of language meaning what the individual intends it to mean. In Interprive Acts, rather than ask whether communication is possible, Professor Harris explores the issues that arise from the question: how does communication occur?

The complexity is interpreted by the author as one of the properties of postnonclassical science. The idea of ‘complexity‘ is studied in the context of contemporary science; the main stages of its genesis are also identified. The author believes that the concept of A. I. Uyemov is a good tool for the theoretical interpretation of the phenomenon of complexity that is so typical for contemporary culture . Base forming factor is the concept of the system, which, on the one hand, (...) expresses the sense of the system , and on the other hand, expresses the intention of human activity. This is not nothing but a systematic representation of modern innovative technologies that realize the unity of values and intentions of human. Systemness acts as a property of reality generated by the creative activity of a human in the implementation of its plans. Hence, the complexity of the systems as a characteristic does not apply to nature or to society per se, but to the human action, activity. Activities can be subdivided into theoretical research and practical technological process. In the first case, we are dealing with postnonclassical science of nature, and the second - with a specific occupation - the science and art of management. In the article, the questions of genesis of a sense and idea of the complexity are studied and an attempt to determine what is the complexity as well as the result of this attempt in modern conditions are given.

The first part of the paper discusses the origins and meaning of democracy relative to the development of Christian political thought through the modern period; it is important here that democracy means something different in the ancient world than it does in the modern. The second part discusses the view of democracy proposed in the formative period of modern Catholic social doctrine in especially from the pontificate of Leo XIII to the Second Vatican Council. The third part analyzes the (...) political thought of St. John Paul II which seems to be the apogee of Catholic thinking about democracy. The fourth part discusses some remaining tensions and problems related to democracy that are articulated partly also in John Paul II’s thought, but in a sharper way in the thought of Pope Benedict XVI and one quite prominent challenge to the Catholic view of democracy in the phenomenon of pluralism. One can see in this history that the Church has gradually come to appreciate democracy not simply as an acceptable form of government, one that is not intrinsically at odds with Christianity, but in a positive sense, as an opportunity for human beings to achieve a level of moral development not available in other regimes. But there remain challenges associated with democracy to government and social life consistent with the natural moral law and to Christian faith. (shrink)

_Purpose._ The purity of consciousness in European culture has practically been turned into an abstraction. Because of this, there are so many discrepancies in understanding its nature. For Heidegger, the question of the purity of human consciousness remains open. Our purpose is to study the purity of European consciousness in the work of M. Heidegger. _Theoretical basis._ We draw on the deep foundations of existential, phenomenological, hermeneutic, religious-philosophical and postmodern Western and Eastern thought. _Originality._ While the early Heidegger was thinking (...) under the sign of Dasein, he did not hear the nature of the "pure consciousness" of human. Nevertheless, temporality for him was such a fundamental property that it determined the depth of understanding not only of being, but also of human consciousness itself (like Dasein). In this context, we begin to understand that the depth of consciousness in the concept of early Heidegger can be associated with its temporality. In fact, towards the end of "Being and Time", Heidegger, thinking more and more about the understanding of time from the horizon of being, begins to form similar ideas about understanding itself, that is, about human consciousness, in the sense that consciousness itself arises from the horizon of time (and being). What, then, is pure human consciousness the pure time? Does not this mean that the original meaning of consciousness is in its directed temporalizing. This temporalizing of consciousness of human (as a thinking being), which arises from the future, is perceived in three modes and reveals the fundamental nature of the consciousness itself (thinking is a stream of consciousness and, in such a context, directed understanding). Paraphrasing Heidegger, we say that the ontological meaning of pure human consciousness is revealed as temporality. Already after writing _Being and Time_, Heidegger thinks about the origins of the European consciousness, its comprehending from the depths (originality) of the being of European culture. _Conclusions._ The early Heidegger seeks the purity of being and, at the same time, strives more and more to understand the essence of the purity of human thinking. All of Heidegger’s work is a consistent transition from human understanding of the purity of being (Dasein) to the purity of thinking of a human himself. In this sense, there is a transformation of M. Heidegger’s consciousness from fundamental ontology (Dasein) in the early period to existential anthropology (human consciousness) in the late period.

This essay aims to reconstruct and defend Pascal’s account of divine hiddenness. In the first section I explain Pascal’s view that divine hiddenness is primarily a function of human volitional aversion and only secondarily a result of God’s intentional action. In the following section I evaluate the primary sense of hiddenness by considering Pascal’s response to the objection that divine goodness requires and divine power makes possible God’s provision of evidence sufficient to overcome human volitional indisposition. While Pascal does (...) think it possible for God to provide such evidence, he argues that this would unjustly harm human freedom and endanger human intellectual understanding. I conclude by addressing a weaker form of the objection through consideration of the second sense of divine hiddenness and Pascal’s surprising view that God’s intentional “hiding” is in fact a progressively deeper entry into the particulars of human history.

In the article, I analyze the current situation in the field of teaching philosophy and also other social sciences and humanities. The point is that in higher school, under various pretexts, many departments and philosophy councils are closed, hours for teaching philosophical courses and seminars are reduced. Teachers of philosophy and other disciplines in higher education, in addition to being overwhelmed, have to spend a lot of time on unnecessary reporting, which for the most part does not reflect the (...) essence of the matter. The policy of education officials and their belief in the need for such reporting and reduction of hours are critically reviewed. I show that in addition to the well-known functions of philosophy, teaching philosophy is of crucial importance today is due to three important circumstances: we live, firstly, in a period of double transition and, secondly, in a period of an anthropological crisis and a crisis of reality, thirdly, due to a crisis of morality and ethics. Only philosophy, based on the methodology, as well as the humanities and social sciences can comprehend modern conditions. The question is about a new start to the practice of teaching philosophy. I propose to introduce a temporary moratorium on the compilation of new teaching programs and start a broad discussion in the philosophical and pedagogical community of the goals and content of the teaching of philosophy. In this regard, I offer my own understanding of the problems and the essence of the teaching of philosophy. I also share my personal experience in teaching philosophy, which includes lecturing and organizing the creative work of small groups of students. (shrink)

Man's relation to culture is not limited simply to knowing it. There are other modalities of this relationship. For one, man in some way lives in culture, he exists in it, even if for some time he does notwardrealize this. Second, he participates in one way or another in the process of forming it, he creates it. Only later does culture become an object of knowledge for him. What makes him study and understand culture if previously he had (...) gotten along without it? Why, in general, does knowledge of culture appear? It is necessary to distinguish between the history of culture, the roots of which are in the distant past, and the history of the knowledge of culture, the source of which is man's discovery of culture. Why and when did this discovery occur? (shrink)

In order to strengthen RI in the private sector, it is imperative to understand how companies organise this process, where it takes place, and what considerations and motivations are central in the innovation process. In this chapter, the questions of whether and where normative considerations play a role in the innovation process, and whether dimensions of RI are present in the innovation process, are addressed. In order answer these research questions, a theoretical framework is developed based on Jones’s theory of (...) ethical decision making and Cooper’s stagegate model of innovation management. In order to answer the research questions, a specific case of innovations that contribute to public health is explored, namely, that of food companies that participate in a Front-of-Pack logo for healthier food. As the use of healthy food logos does not necessarily have a positive impact on sales and profits, it is expected that in the decision-making process, as part of their innovation process, companies make several trade-offs between economic, technical and moral factors. As the social-ethical values at stake in corporate innovation processes have remained to a large extent unexplored in research on innovation management, the aim of this chapter is to identify the motivations and barriers for companies embracing and continuing a FoP logo for healthier food, and to assess whether ethical considerations play a role in this innovation process. From the findings in this research, it will become clear that although the studied companies participated in a programme for healthy food and thus are responsive to the needs of society, and although the companies feel responsible for public health, ethical considerations do not play a central role in the operational innovation process. Instead, technical and economic considerations seem to prevail in the operational innovation process. Furthermore, none of the procedural dimensions of RI seems to be present at this level in the innovation trajectory. It is argued that this may be an indication that the ethical decision-making process for RI is not located at the level of the operational innovation process itself, but is something that might be located on a higher strategic level in the company. It is at this level that the moral decision is taken to adopt the FoP logo and to engage in the RI process. The findings cast a new light on the discourse on RI in general, and in the private sector in particular. (shrink)

The Italian parliament passed the law on assisted reproduction after a heated debate. The promulgation of this law (Law 40/2004) is the end point of a long and troubled journey that has seen many bills come and go, all of which have failed. The law consists of a whole set of regulations that will have a great impact on health and on society in general. The law is against many of the technical practices of assisted reproduction; several such practices are (...) banned. This paper outlines ethical and medicolegal issues arising in connection with the law. The law states that no more than three embryos must be created at any one time and all the embryos created must be transferred together even if the couple does not need all the embryos. Embryo cryopreservation is also forbidden, as is assisted reproductive technology (ART), which uses a third party in any way, and the screening of embryos for genetic defects. (shrink)

The article discusses the features of the love-passionate plot in the stories of Ivan Bunin. The question is raised why Bunin, describing the strange or immoral acts of the heroes, does not condemn them, and in general draws a bright, sometimes sad atmosphere. Analysis of L. S. Vygotsky’s short story “Easy Breathing” by Bunin allows us to express an idea about a certain strategy for building Bunin’s works. Based on this consideration, the methods by which Bunin achieves the effect (...) of perception of the characters he needs are analyzed. There are three such techniques: the convergence of the actions and behavior of the characters with the life and breath of nature, the depiction of the life of the characters from the point of view that Bunin needs, and the endowment of the characters with personality traits that exclude ethical characteristics and problems. The scientific explanation of Bunin's artistic constructions is based on the analysis of mental trauma (caused by the departure of the first wife and the horrors of the revolution), artistic understanding of the events that interest the writer, and the peculiarities of the conceptualization of these events. In addition, it is proposed to take into account that Bunin began and became famous as a poet, and as a poet he composed his prose partly according to the laws of versification. (shrink)

It has been widely held that presentism cannot easily accommodate Einstein’s Special Theory of Relativity account of the relativity of simultaneity because presentism privileges successively unique times ontologically. Recently Brogaard and Marlow argued that presentism does not deserve the attribution of this defect because it may well be that Einstein’s account of the relativity of simultaneity is defective, leaving it open to establishing a view of absolutist simultaneity friendlier to presentism. Specifically Brogaard and Marlow present an argument against one (...) of Einstein’s most famous accounts of the relativity of simultaneity, and moreover raise doubts about whether Einstein availed himself of absolutist frames in some of his explanations of relativity. I will dismiss both of these charges, and thus argue that the complaint against presentism from SR stands. (shrink)

Biological mimicry is regarded by many as a textbook illustration of Darwin’s idea of evolution by random mutation followed by differential selection of reproductively fit specimens, resulting in gradual phenotypic change in a population. In this paper, I argue that some cases of so-called mimicry are probably merely look-a-likes and do not gain an advantage due to their similarity in appearance to something else. In cases where a similar appearance does provide a benefit, I argue that it is possible (...) that these forms of mimicry were created in a single generation. An interpretive response to an appearance as a sign can make a new structure perform drastically differently in an environment. In such cases, Darwin’s natural selection mechanism only helps to explain gradual the spread of these new forms, not the creation of them. I argue that biosemiosis should be regarded as a much more powerful mechanism for affecting evolutionary trajectories than the gradualist view allows. I focus on two cases of butterfly mimicry: the Viceroy (Nymphalidae: Limenitis archippus) and Monarch (Nymphalidae: Danaus plexippus) butterflies, supposed Müllerian mimics, and deadleaf mimic butterflies (Kallima).
