Both the concept of a Darwinian tree of life (TOL) and the possibility of its accurate reconstruction have been much criticized. Criticisms mostly revolve around the extensive occurrence of lateral gene transfer (LGT), instances of uptake of complete organisms to become organelles (with the associated subsequent gene transfer to the nucleus), as well as the implications of more subtle aspects of the biological species concept. Here we argue that none of these criticisms are sufficient to abandon the valuable TOL concept (...) and the biological realities it captures. Especially important is the need to conceptually distinguish between organismal trees and gene trees, which necessitates incorporating insights of widely occurring LGT into modern evolutionary theory. We demonstrate that all criticisms, while based on important new findings, do not invalidate the TOL. After considering the implications of these new insights, we find that the contours of evolution are best represented by a TOL. (shrink)

This book chapter addresses two questions. First, can targeted killing by drones in non-battlefield zones be justified on basis of just war theory? Second, will the proliferation and expansion of combat drones in warfare, including the introduction of autonomous drones, be an obstacle to initiating or executing wars in a just manner in the future? The first question is answered by applying traditional jus ad bellum and jus in bello principles to the American targeted killing campaign in Pakistan; the second (...) question is answered on basis of principles of “just military preparedness” or jus ante bellum, a new category of just war thinking. It is concluded that an international ban on weaponized drones is morally imperative and, certainly, that an international treaty against autonomous lethal weapons should be adopted. (shrink)

William Whewell’s 19th century philosophy of science is sometimes glossed over as a footnote to Kant. There is however a key feature of Whewell’s account worth noting. This is his appeal to Aristotle’s form/matter hylomorphism as a metaphor to explain how mind and world merge in successful scientific inquiry. Whewell’s hylomorphism suggests a middle way between rationalism and empiricism reminiscent of experience pragmatists like Steven Levine’s view that mind and world are entwined in experience. I argue however that Levine does (...) not adequately explain exactly how mind and world entwine. He could nonetheless do so if he appealed to Whewell’s hylomorphic metaphor. We may prefer a reductive metaphysical explanation, but I suggest that pragmatists only have recourse to metaphor in this case. Both reductive and metaphorical explanations can enjoy great explanatory power if they exhibit a suitable measure of what I will call sematic distance. Semantic distance measures how close or how far apart explanandum and explanans are from each other in meaning. Metaphorical explanation - as evident in Whewell’s hylomorphism and as detailed via the notion of semantic distance - presents a valuable new explanatory tool to those who hold that mind and world are entwined sans recourse to metaphysics.

The neo-Kantian Hermann Cohen famously wrote that Kant “is the true and real originator of German socialism.” This paper seeks to explicate Cohen’s socialist reconstruction of Kant’s ethics and show that this reconstruction overcomes some weaknesses of Kant’s ethics. In conclusion, the paper discusses the contemporary relevance of Cohen’s cooperative socialism.

I identify two versions of the scientific anti-realist’s selectionist explanation for the success of science: Bas van Fraassen’s original and K. Brad Wray’s newer interpretation. In Wray’s version, psycho-social factors internal to the scientific community – viz. scientists’ interests, goals, and preferences – explain the theory-selection practices that explain theory-success. I argue that, if Wray’s version were correct, then science should resemble art. In art, the artwork-selection practices that explain artwork-success appear faddish. They are prone to radical change over time. (...) Theory-selection practices that explain theory-success in science are however not faddish. They are mostly stable; that is, long-lived and consistent over time. This is because scientists (explicitly or implicitly) subscribe to what I will call the testability norm: scientific theories must make falsifiable claims about the external physical world. The testability norm and not psycho-sociology explains the theory-selection practices that explain theory-success in science. Contra Wray, scientific anti-realists can then maintain that the external physical world (as expressed in the testability norm) explains theory-success. (shrink)

Review of Willem Schinkel's Theorie van de Kraal, de Hamsteraar, and Pandemocratie.

Several complexity theorists draw a sharp and ontologically robust distinction between (merely) complicated systems and (genuinely) complex systems. I argue that this distinction does not hold. Upon fine-grained analysis, ostensibly complicated systems turn out to be complex systems. The purported boundary between the complicated and the complex appears to be vague rather than sharp. Systems are complex by degrees.

In this article, we sketch a new approach to law and ethics. The traditional paradigm, exemplified in the debate on liberal moralism, becomes increasingly inadequate. Its basic assumptions are that there are clear moral norms of positive or critical morality, and that making statutory norms is an effective method to have citizens conform to those norms. However, for many ethical issues that are on the legislative agenda, e.g. with respect to bioethics and anti-discrimination law, the moral norms are controversial, vague (...) or still evolving. Moreover, law proves not to be a very effective instrument. Therefore, we need a new paradigm, both for descriptive and for normative analysis. This interactive paradigm, as a normative position, can be summarised in two theses. The process of legislation on ethical issues should be structured as a process of interaction between the legislature and society or relevant sectors of society, so that the development of new moral norms and the development of new legal norms may reinforce each other. And legislation on ethical issues should be designed in such a way that it is an effective form of communication which, moreover, facilitates an ongoing moral debate and an ongoing reflection on such issues, because this is the best method to ensure that the practice remains oriented to the ideals and values the law tries to realise.

Compassion unites people during times of suffering and distress. Unfortunately, compassion cannot take away suffering. Why then, is compassion important for people who suffer? Nurses work in a domain where human suffering is evidently present. In order to give meaning to compassion in the domain of professional care, it is necessary to describe what compassion is. The purpose of this paper is to explore questions and contradictions in the debate on compassion related to nursing care. The paper reviews classical philosophers (...) as well as contemporary scientists' main arguments on compassion. First, I will examine the relationship between compassion and suffering. Second, how does one recognize serious suffering? This issue raises questions about the role of imagination and the need for identification. Third, literature describes compassion as an emotion. Some philosophers consider emotions uncontrollable feelings; others see a clear rational dimension in emotions. In order to determine what compassion is, it is necessary to weigh these contradictional arguments. Fourth, I will discuss motives for compassion. Is compassion an act of altruism or egoism? In this debate Nietzsche and Schopenhauer are well‐known opponents. Today, analysis of their arguments leads to some surprising conclusions. Fifth, there is the issue of fault and compassion. Can we only feel compassionate when people who suffer are not to blame for their own suffering? Such a condition faces professional caretakers with a dilemma which needs a thorough analysis if compassion is to be of use in the field of professional care. Finally, I will explore the moral meaning of compassion. Compassion, described as a concept with cognitive as well as affective dimensions, also has volitional and behavioural aspects. These aspects specifically are of importance to nursing care and further research of compassion in the nursing domain. (shrink)

Should the U.N. Security Council use its coercive powers to bring about effective climate change mitigation? This question remains relevant considering the inadequate mitigation goals set by the signatories of the Paris Climate Accord and the ramifications of U.S. withdrawal from the Accord. This paper argues that the option of the unsc coercing climate change mitigation through military action, or the threat thereof, is morally flawed and ultimately antithetical to effectively addressing climate change. This assessment is based significantly on the (...) application of jus ad bellum principles of just war theory, incorporating some feminist critiques of this theory. (shrink)

International law grants to legitimate combatants the right to kill enemy soldiers both in wars of aggression and defensive wars. A main argument in support of this “combatant’s privilege” is Michael Walzer’s doctrine of the “moral equality of soldiers.” The doctrine argues that soldiers fighting in wars of aggression and defensive wars have the same moral status because they both typically believe that justice is on their side, and their moral choices are equally severely restricted by the overwhelming coercive powers (...) of the state, including propaganda, conscription, and harsh penalties for the refusal to fight. Recently, this doctrine has been convincingly refuted, at least with regard to aggressor soldiers who are part of professional volunteer armies in democratic societies. However, Walzer’s critics have not challenged combatant’s privilege, primarily for a variety of pragmatic reasons. This paper examines these reasons, finds them not decisive, and articulates a modest proposal for denying, under some conditions, combatant’s privilege to aggressor soldiers, making their very participation in a war of aggression a war crime. It is concluded that unrestricted combatant’s privilege is in tension with the aim of the United Nations “to save succeeding generationsfrom the scourge of war.”. (shrink)

In this paper I question the morality of U.S. military supremacy or hegemony in terms of what constitute the legitimate use of military force and the proper preparation for using such force. I first discuss in a somewhat synoptic fashion how American hegemonic military force has been justified in dishonest ways and wrongly executed. Next, I show that Just War Theory needs to be revised in order to come to a convincing assessment of U.S. military hegemony and its use of (...) military force. This leads me to propose “just military preparedness,” consisting of five principles of just military preparedness, as a new category of JWT. The failure of the United States to satisfy the principles puts into question its very capability of justly resorting to military force, of lawfully executing force, and of establishing a just peace after war. The principles also point to a more humane alternative of how the United States could meet security threats and sustain a peaceful international order. (shrink)

On the same day, 23 September 2003, that President George W. Bush defended his Iraq policy to the General Assembly of the United Nations, Secretary-General Kofi Annan also spoke to the Assembly. Annan reiterated his opposition to the view that states may independently be justified in using military force “preemptively” to avoid the dangers posed by the spread of weapons of mass destruction among states and terrorists, including nuclear, biological, and chemical weapons.

Theoretical models for physician-patient communication in clinical practice are described in literature, but none of them seems adequate for solving the communication problem in clinical practice that emerges in case of factitious disorder. Theoretical models generally imply open communication and respect for the autonomy of the patient. In factitious disorder, the physician is confronted by lies and (self)destructive behaviour of the patient, who in one way or another tries to involve the physician in this behaviour. It is no longer controversial (...) that the physician should communicate his consideration of a factitious disorder without insistence that the patient accepts this diagnosis. However, the balance between patient autonomy and open communication on the one hand, and the preservation of the patient's health, physician integrity and of a constructive physician-patient relationship on the other is easily disrupted. In this article, an epistemological model is described to facilitate a positive outcome of confrontation in treatment of factitious disorder. Analysing the problem in terms of systems theory will help the physician to assess what information is appropriate to use in which phase of the patient's treatment, while preserving the physician-patient relationship.

The modern critical approach to things hagiographical still wavers when it comes to taking leave of twelve lines of iambic invective, branded with wonderful delicacy of touch on the saintly foreheads of two Palestinian brothers, Theodore and Theophanes, the so-called “Graptoi”. Barry Baldwin, noting that C.A. Trypanis, unlike the great B. Bury and others, was inclined to disbelieve the story, could not help expressing the hope that it was true (An Anthology of Byzantine Poetry, Amsterdam 1985, pp. 142–3). It is (...) of course only one of the many stories concocted by iconodule propaganda. The central question has to be formulated in more general terms: how is history made? History here primarily in the sense of the construction of the past by the Byzantines themselves, was embodied in historical narratives moving between hagiography and historiography. Trying to lay bare the basis and elements of such constructs will always remain a major task of critical historical scholarship. (shrink)

In order to overcome the unhealthy perspective of body-mind dualism and become capable of holding the “higher” and healthier perspective of body and mind as will to power, Nietzsche stresses that one must engage in a process of cultivation of the body. Such a practice of self-cultivation involves leaving behind incorporated illusory and life-denying perspectives and incorporating more “truthful” and affirmative perspectives on life. In this article, Nietzsche’s views on the body and its cultivation will be further explored and compared (...) with Japanese Buddhist thought on body, mind, and cultivation. In Japanese thought, the notion of shinjin-ichinyō (oneness of body and mind) was developed in order to overcome a dualistic approach to body and mind. The unity of body and mind plays an essential part in the philosophies of both Kūkai and Dōgen. Whereas in early Indian Buddhism, self-cultivation took place primarily through the mind (citta), in Japanese Buddhist practice the body, not the mind, is the primary locus as exemplified in Dōgen’s somatic practice of zazen. Although from the everyday perspective, body and mind are experienced as two separate things, a higher perspective is possible in which body-mind is experienced as a continually changing configuration of dharmas that doesn’t contain any “I.” Such a higher perspective is called “samadhic awareness” by Dōgen, in which “body and mind are cast off” (shinjin totsuraku). For both Nietzsche and Dōgen, their “philosophy am Leitfaden des Leibes” does not aim at discovering “truths” by means of introspection and thinking, but at increasing the body’s capacity for the incorporation of new and liberating perspectives.

Paul Cilliers has developed a novel post-structural approach to complexity that has influenced several writers contributing to the current complexity literature. Concomitantly however, Cilliers advocates for modelling complex systems using connectionist neural networks (rather than analytic, rule-based models). In this paper, I argue that it is dilemmic to simultaneously hold these two positions. Cilliers’ post-structural interpretation of complexity states that models of complex systems are always contextual and provisional; there is no exclusive model of complex systems. This sentiment however appears (...) at odds with Cilliers’ promotion of connectionist neural networks as the best way to model complex systems. The lesson is that those who currently follow Cilliers’ post-structural approach to complexity cannot also develop a preferred model of complex systems, and those who currently advocate for some preferred model of complex systems cannot adopt the post-structural approach to complexity without giving up the purported objectivity and/or superiority of their preferred model.

As humans, we frequently engage in mental time travel, reliving past experiences and imagining possible future events. This study examined whether similar factors affect the subjective experience associated with remembering the past and imagining the future. Participants mentally “re-experienced” or “pre-experienced” positive and negative events that differed in their temporal distance from the present , and then rated the phenomenal characteristics associated with their representations. For both past and future, representations of positive events were associated with a greater feeling of (...) re-experiencing than representations of negative events. In addition, representations of temporally close events contained more sensorial and contextual details, and generated a stronger feeling of re-experiencing than representations of temporally distant events. It is suggested that the way we both remember our past and imagine our future is constrained by our current goals. (shrink)

This article presents findings from an interview study of human rights practitioners who assist relatives of the disappeared from Chechnya with their complaints before the European Court of Human Rights (ECtHR). These practitioners work for nongovernmental organizations (NGOs). The study contributes to the scant literature on NGO litigation before the ECtHR and to the social scientific literature on how human rights are actively practiced. It investigates the NGOs’ intermediary position between the ECtHR and the relatives of the disappeared in Chechnya. (...) Consequently, this article asserts that a significant aspect of this position lies in the practitioner’s capacity to mediate between an ambition to externalize local grievances to the ECtHR and the relatives’ hopes that the ECtHR can bring certainty to the uncertain loss of their disappeared relatives. From this position, several dilemmas emerge as to how international legal mechanisms can provide remedies following disappearances. (shrink)

We analyze the cognitive strategies underlying performance in the Number task, a Math game that requires both arithmetic fluency and mathematical creativity. In this game all elements in a set of numbers have to be used precisely once to create a target number with basic arithmetic operations. We argue that some instances of this game are NP complete, by showing its relation to the well-known Partition problem. We propose heuristics based on the distinction in forward and backward reasoning. The Number (...) Game is part of Math Garden, a popular online educational platform for practicing and monitoring math skills using innovations in computerized adaptive testing. These educational games generate enormous amounts of rich data on children's cognitive development. We found converging evidence for the use of forward proximity heuristics in the data of Math Garden, consisting of more than 20 million answers to 1,700 items. Item difficulties and the structure of correct answers were analyzed. (shrink)

To understand pre-Fregean theories of judgment and proposition, such as those found in Locke and the Port-Royal logic, it is important to distinguish between propositions in the modern sense and propositions in the pre-Fregean sense. By making this distinction it becomes clear that these pre-Fregean theories cannot be meant to solve the propositional attitude problem. Notwithstanding this fact, Locke and Arnauld are able to make a distinction between asserted and unasserted propositions (in their sense). The way Locke makes this distinction (...) turns out to be very different from the way it is made by Arnauld. (shrink)

Background Notwithstanding the need to produce evidence-based knowledge on medications for pregnant women, they remain underrepresented in clinical research. Sometimes they are excluded because of their supposed vulnerability, but there are no universally accepted criteria for considering pregnant women as vulnerable. Our aim was to explore whether and if so to what extent pregnant women are vulnerable as research subjects. Method We performed a conceptual and empirical analysis of vulnerability applied to pregnant women. Analysis A conceptual analysis supports Hurst's definition (...) of vulnerability. Consequently, we argue that pregnant women are vulnerable if they encounter an identifiably increased likelihood of incurring additional or greater wrong. According to the literature, this increased likelihood could exist of four alleged features for pregnant women's vulnerability: informed consent, susceptibility to coercion, higher exposure to risk due to lack of knowledge, vulnerability of the fetus. Discussion Testing the features against Hurst's definition demonstrates that they all concern the same issue: pregnant women are only vulnerable because a higher exposure to risk due to lack of scientific knowledge comprises an increased wrong. Research Ethics Committees have a responsibility to protect the vulnerable, but a higher exposure to risk due to lack of scientific knowledge is a much broader issue and also needs to be addressed by other stakeholders. Conclusions The only reason why pregnant women are potentially vulnerable is to the extent that they are increasingly exposed to higher risks due to a lack of scientific knowledge. Accordingly, the discussion can advance to the development of practical strategies to promote fair inclusion of pregnant women in clinical research. (shrink)

The central thesis of this paper is that, for most issues of multiculturalism, regarding them as a problem of tolerance puts us on the wrong track because there are certain biases inherent in the principle of tolerance. These biases -- individualism, combined with a focus on religion and a focus on beliefs rather than on persons or practices -- can be regarded as distinctly Protestant. Extending the scope of tolerance may seem a solution but if we really want to counter (...) these biases, the principle of tolerance becomes so general that it loses any distinctive meaning. Therefore, we should accept the limited scope of tolerance and its biases. The principle of tolerance can still be useful for some problems where there is a clear and direct link to political or religious beliefs. Moreover, it should be cherished as a more general attitude or practice in Dutch society. For most problems of multiculturalism, however, we should appeal to broader theoretical frameworks that do justice to persons and practices. (shrink)

Prima facie, we make successful decisions as we act on and intervene in the world day-to-day. Epistemologists are often concerned with whether rationality is involved in such decision-making practices, and, if so, to what degree. Some, particularly in the post-structuralist tradition, argue that successful decision-making occurs via an existential leap into the unknown rather than via any determinant or criterion such as rationality. I call this view radical voluntarism (RV). Proponents of RV include those who subscribe to a view they (...) call Critical Complexity (CC). In this paper, I argue that CC presents a false dichotomy when it conceives of rationality in Cartesian – i.e. ideal and transcendental – terms, and then concludes that RV is the proper alternative. I then outline a pragmatist rationality informed by recent work in psychology on bounded rationality, ecological rationality, and specifically embodied rationality. Such a pragmatist rationality seems to be compatible with the tenets of post-structuralism, and can therefore replace RV in CC. (shrink)

In the Netherlands fertility doctors increasingly formulate protocols, which oblige patients to quit their unhealthy lifestyle before they are admitted to IVF procedures. We argue that moral arguments could justify parenting protocols that concern all future parents. In the first part we argue that want‐to‐be parents have moral responsibilities towards their future children to prevent them from harm by diminishing or eliminating risk factors before as well as during the pregnancy. This is because of the future children's potential to become (...) of a certain type, more specifically: a person that will be the want‐to‐be parents' child. Want‐to‐be parents intend to become pregnant and therefore have an additional moral reason to diminish the risks. Also, people who become pregnant unintentionally have the responsibility to prevent their children from harm, unless they become pregnant due to contraception failure. All people not wanting to become pregnant should use contraception methods carefully.In the second part of this paper we translate the want‐to‐be parents' responsibilities into practice. We distinguish four determinants of risk factors: modifiability, chance, severity and effort. We examine some evidence‐based risk factors based on these variables and deduce levels of responsibility.In conclusion, formulating informal requirements for want‐to‐be parents is morally required and therefore also for want‐to‐be parents in need of medical assistance. The protocols developed by fertility doctors in the Netherlands could be seen as the precursor for a general, informal Parenting Protocol that could be developed on the basis of an extended and thoroughly debated risk‐responsibility analysis.

Human cognition is unique in the way in which it relies on combinatorial (or compositional) structures. Language provides ample evidence for the existence of combinatorial structures, but they can also be found in visual cognition. To understand the neural basis of human cognition, it is therefore essential to understand how combinatorial structures can be instantiated in neural terms. In his recent book on the foundations of language, Jackendoff described four fundamental problems for a neural instantiation of combinatorial structures: the massiveness (...) of the binding problem, the problem of 2, the problem of variables, and the transformation of combinatorial structures from working memory to long-term memory. This paper aims to show that these problems can be solved by means of neural “blackboard” architectures. For this purpose, a neural blackboard architecture for sentence structure is presented. In this architecture, neural structures that encode for words are temporarily bound in a manner that preserves the structure of the sentence. It is shown that the architecture solves the four problems presented by Jackendoff. The ability of the architecture to instantiate sentence structures is illustrated with examples of sentence complexity observed in human language performance. Similarities exist between the architecture for sentence structure and blackboard architectures for combinatorial structures in visual cognition, derived from the structure of the visual cortex. These architectures are briefly discussed, together with an example of a combinatorial structure in which the blackboard architectures for language and vision are combined. In this way, the architecture for language is grounded in perception. Perspectives and potential developments of the architectures are discussed. Key Words: binding; blackboard architectures; combinatorial structure; compositionality; language; dynamic system; neurocognition; sentence complexity; sentence structure; working memory; variables; vision.

Ernest Mandel theorised the capitalist world economy as an articulated system of capitalist, semi-capitalist and precapitalist relations of production, linked to each other by capitalist relations of exchange and domination by the capitalist world market. This seems to be an interesting starting point for an historically well-founded theory, building on and going beyond Marx's work, of the worldwide expansion of the capitalist mode of production from its origins to the present. In his attempt to formulate his theory, Mandel did not (...) succeed in resolving all difficulties, however. His main works – Marxist Economic Theory and Late Capitalism – show a number of dangling loose ends. The central question is whether these loose ends are merely technical difficulties or whether they reveal fatal flaws in the theory as a whole. In order to come a step closer to answering this question, a conference was organised in Amsterdam, November 2003. This introduction formulates the five, closely interrelated issues that were highlighted at this conference. (shrink)

It has been claimed that the ability to remember the past and the ability to project oneself into the future are intimately related. We sought support for this proposition by examining whether individual differences in dimensions that have been shown to affect memory for past events similarly influence the experience of projecting oneself into the future. We found that individuals with a higher capacity for visual imagery experienced more visual and other sensory details both when remembering past events and when (...) imagining future events. In addition, individuals who habitually use suppression to regulate their emotions experienced fewer sensory, contextual, and emotional details when representing both past and future events, while the use of reappraisal had no effect on either kind of events. These findings are consistent with the view that mental time travel into the past and into the future relies on similar mechanisms. (shrink)

Les décisions politiques sur les risques environnementaux complexes font fréquemment intervenir des éléments scientifiques contestés. Il n’y a généralement pas de « faits » qui conduisent à une politique correcte unique. Les éléments de preuve qui sont intégrés dans les avis scientifiques destinés à une décision politique nécessitent une évaluation de leur qualité. En 2003, l’Agence néerlandaise d’évaluation environnementale a adopté une méthode standardisée, désignée sous le nom de « guide », dans le cadre de laquelle les principaux aspects de (...) la production et de l’utilisation des connaissances sont présentés grâce à une liste de contrôle visant à l’évaluation et à la communication des incertitudes. Dans cet article, nous présentons des résultats de l’application de ce guide à la controverse sur les risques des particules en suspension. La délibération active sur l’incertitude dans un contexte d’expertise entraîne un processus d’apprentissage commun entre les experts et les décideurs politiques, ce qui conduit à une meilleure prise de conscience du phénomène d’incertitude et de ses implications politiques.Policy decisions on complex environmental risks often involve disputed science. Typically, there are no “ facts” to support a single unequivocally correct policy. The evidence provided in scientific studies for policy-making decisions requires high-quality assessment. In 2003, the Netherlands Environmental Assessment Agency adopted a standardized method, referred to as “guidelines”, whereby key quality aspects of knowledge production and use are presented in the form of a checklist for uncertainty assessments and communication. In this article, we present the outcomes of applying the guidelines in controversies on the risks of ambient particulate matter. In the policy–advisory context, active deliberation on uncertainty produces a common learning process for advisors and policy makers, which leads to a deeper understanding and increased awareness of the phenomenon of uncertainty and its policy implications.
