To examine whether high moral reasoning competence of adolescents is associated with low levels of bullying, and to understand whether moral disengagement mediates or moderates this relationship, 925 German children ranging from 11 to 17 years of age (M = 14.18, S = 1.21) completed questionnaires on moral reasoning competence and moral disengagement in surveys at three different schools. The children were classified according to their bullying role, based on a peer- nomination procedure. Multinomial logistic regression analyses showed that moral (...) reasoning competence negatively predicted whether a student took an aggressive role. Moral disengagement partially mediated this relationship. Corresponding effects for defenders and outsiders were not found. These results extend previous findings about the effect of moral reasoning on bullying in primary school. The implications for the prevention of bullying are discussed. (shrink)

Dr. Norman L. Geisler has been called the "father of evangelical Christian philosophy." He has written more than one hundred books and taught at universities and top seminaries for some fifty-six years. He was the first president of the Evangelical Philosophical Society and the founder and first president of the International Society of Christian Apologetics. He has spoken or debated in more than two dozen countries and held pastoral/pulpit ministries in four states. Many view him as a cross between (...) Thomas Aquinas and Billy Graham. No one has done more to communicate the modern challenges of the Faith to the "average" Christian, to the church, and to the academy. This volume offers creative and constructive essays from twenty-three contributors, all notable in their own right, who preserve and propagate Dr. Geisler's ideas and express appreciation for his influence. Those who know him best say he is "true, faithful, and blessed by God!" -- from book cover. (shrink)

Ethical thought experiments such as the trolley dilemma have been investigated extensively in the past, showing that humans act in utilitarian ways, trying to cause as little overall damage as possible. These trolley dilemmas have gained renewed attention over the past few years, especially due to the necessity of implementing moral decisions in autonomous driving vehicles. We conducted a set of experiments in which participants experienced modified trolley dilemmas as drivers in virtual reality environments. Participants had to make decisions between (...) driving in one of two lanes where different obstacles came into view. Eventually, the participants had to decide which of the objects they would crash into. Obstacles included a variety of human-like avatars of different ages and group sizes. Furthermore, the influence of sidewalks as potential safe harbors and a condition implicating self-sacrifice were tested. Results showed that participants, in general, decided in a utilitarian manner, sparing the highest number of avatars possible with a limited influence by the other variables. Derived from these findings, which are in line with the utilitarian approach in moral decision making, it will be argued for an obligatory ethics setting implemented in ADVs. (shrink)

Feministische Aktivist*innen haben sich schon immer verschiedener Medien bedient, um zu kommunizieren, sich zu artikulieren und zu vernetzen. Durch die Digitalisierung und die damit verbundenen Möglichkeiten erweitern sich feministische Aktionsräume und verlagern sich zunehmend ins Social Web. So lässt sich feststellen, dass Plattformen wie twitter, instagram oder auch facebook vielfach genutzt werden, um feministische Anliegen in die Öffentlichkeit zu tragen. Der gegenwärtige mediale Diskurs um feministische Ideen und Forderungen wird dabei maßgeblich durch antifeministische Akteur*innen beeinflusst, deren Anliegen es ist, feministische (...) Stimmen aus dem medialen Raum zu verbannen. Die vorliegende Arbeit greift diese Thematik auf und geht der Frage nach, wie feministische Aktivist*innen antifeministische, digitale Gewalt wahrnehmen und damit umgehen. Die Ergebnisse verweisen darauf, dass insbesondere Aspekte der Sexuellen Identität und der Mehrfachdiskriminierung entscheidend sind für das Ausmaß der digitalen Gewalt, die erfahren wird. Weiterhin wird deutlich, welche Rolle Solidarität, Vernetzung und Empowerment im Kampf gegen den Antifeminismus spielen. Die Autorin Anja Roß studierte Pädagogik und Soziologie an der Universität Bielefeld. Sie arbeitet als wissenschaftliche Mitarbeiterin am Institut für Pädagogik an der Universität Oldenburg. Hier promovierte sie 2024 zum feministischen Aktivismus im Social Web und den Umgang mit digitaler Gewalt. (shrink)

We describe a formal framework for analyzing how statistical properties of natural environments and the process of natural selection interact to determine the design of perceptual and cognitive systems. The framework consists of two parts: a Bayesian ideal observer with a utility function appropriate for natural selection, and a Bayesian formulation of Darwin's theory of natural selection. Simulations of Bayesian natural selection were found to yield new insights, for example, into the co‐evolution of camouflage, color vision, and decision criteria. The (...) Bayesian framework captures and generalizes, in a formal way, many of the important ideas of other approaches to perception and cognition. (shrink)

In light of new biomedical technologies, such as artificial reproduction, stem cell research, genetic selection and design, the question of what we owe to future persons-and unborn life more generally-is as contested as ever. In A Theory of Unborn Life: From Abortion to Genetic Manipulation, author Anja J. Karnein provides a novel theory that shows how our commitments to persons can help us make sense of our obligations to unborn life. We should treat embryos that will develop into persons (...) in anticipation of these persons. But how viable is this theory? Moreover, what does it mean to treat embryos in anticipation of the future persons they will develop into? Exploring the attractiveness of this approach for Germany and the U.S. - two countries with very different legal approaches to valuing unborn life-Karnein comes to startling conclusions to some of today's greatest ethical and legal debates.

In his recent book, The Empirical Stance, Bas van Fraassen forcefully raises the question of what a philosophical position can or should be. He mainly discusses this question with regard to empiricism but his discussion makes it clear that he takes his proposed answer to be generalizable: not only empiricism but philosophical positions in general should be understood as stances rather than dogmata. The first part of this essay is devoted to an examination of van Fraassen’s critique of ‘naïve’ or (...) dogmatic empiricism, which represents an integral part of his argument for ‘stance’ empiricism. It will be argued that, contrary to van Fraassen’s view, not all versions of naïve empiricism run into the problems identified by him. In the second part of the paper the case will be made that, contrary to van Fraassen’s thesis, the stance empiricist is in at least as bad a position as the naïve empiricist with regard to the task of providing a radical critique of metaphysics, which van Fraassen takes to be an essential task that any empiricist should be able to accomplish. The third part of this essay concerns van Fraassen’s general proposal, and examines the question whether a philosophical position can possibly consist in a stance. It will be suggested that this is not the case. With regard to empiricism this has the implication that if one wants to be a philosopher and an empiricist at the same time one needs to subscribe to a form of naïve empiricism. Furthermore, it will be proposed that as a philosopher-empiricist one should want, or, at least, allow some form of metaphysical theorizing to be part of the philosophical enterprise after all.

Most commentators agree that Leibniz advocates some version of a doctrine of the ideality or reducibility of relations, but there is considerable disagreement about what exactly this doctrine means. I argue that Leibniz’s views on relations are more complex than has been previously appreciated, and that, despite some ‘reductionist’ strands in Leibniz’s position, it is seriously misleading to describe him as a reductionist about relations without adding some important qualifications. The complexity of Leibniz’s views on relations tends to be obscured (...) by the common assumption that they can be captured in one unified thesis, or a small number of closely related theses, and by the widespread neglect to take Leibniz’s division of reality into several ontological levels into consideration. I disentangle ten Leibnizian theses about relations, extrinsic denominations, and their relation to intrinsic denominations. Some of these theses express a kind of dependence of extrinsic denominations on intrinsic ones, and some of them can even be counted as articulations of a form of reductionism. But, overall, the general tenor of Leibniz’s position on extrinsic denominations remains non-reductionist. (shrink)

When the first publication of Hans-Georg Gadamer's magnum opus Wahrheit und Methode came to life in I960, the work was initially received with a slight sense of puzzlement and yet concurrently acknowledged as monumental. The title, in English, Truth and Method, was regarded by the philosophical community both in Germany and abroad as being somewhat obscure, as Gadamer himself would later admit, but the ingeniousness of the book's content could hardly be debated. Since its initial publication, Truth and Method has, (...) respectively helped to expand and light up the horizon of modern hermeneutics by provoking, at once, a reconsideration of the phenomenon of understanding while, at the same time, enlivening the debate over scientific methodology and its exclusive claim to truth. The central aim of the present thesis has been to focus on Part I of Truth and Method, concentrating primarily on the 'guiding humanistic concepts' and the experience of truth in art, to clarify Gadamer's understanding of truth and to shed new light as to how the experience of tmth is to be grasped in relation to the human sciences, i.e. the humanities. The humanistic concepts, I believe, are vital to understanding the experience of truth. One reason, which leads me to this conclusion, is that in Truth and Method Gadamer begins his philosophical undertaking with the elucidation of the humanistic concepts rather than with a direct exposition of truth. By opening with the humanistic concepts, Gadamer seems to demonstrate subtly the phenomenological and ontological nature of knowledge and understanding. The outcome of this manoeuvre is that one comes to realise that truth does not simply belong to method and that it is not something which can be defined solely as 'absolute certainty'. Moreover, in my interview with Professor Gadamer, the humanistic concepts, he explained to me, are the most 'natural' and 'original' concepts. By natural and original he means that these concepts are intrinsic. They evolve from life as well as being a part of life, i.e. a way of living. Thus these concepts, he affirmed, represent 'a way of life' and a way to truth. Consequently, insofar as comprehending the phenomenon of truth, I believe any and every investigation of the concept of truth must begin with the understanding of the humanistic tradition. The following thesis however does not end simply with the humanistic concepts. It also devotes to examining the truth-claim or the 'truth-experience' of art. This part of the inquiry centres on two important questions: How are we to understand art? What does it mean to experience art? The challenge here has been to show how Gadamer overcomes Kant's subjectivation of the aesthetic experience and to demonstrate how and why Gadamer considers the experience of art as the 'self-presentation' of being. In surveying the various works of criticism I have tried to draw attention to what seem to me to be the most insightful comments and analyses. If 1 have failed in any way to supply proper acknowledgement to ideas, which might seem close to other critical works, I offer my apologies. As I am sure those in the research business know well, in reflection ideas often interfuse with one's own, making it difficult sometimes to discriminate between one's own ideas from another's. However, I have tried my best to keep from that error. (shrink)

Thema dieses Buches ist weder die Philosophie der Zeit noch eine römische Chronologie, sondern eine Untersuchung der literarischen Reflexion der Zeitordnung in Rom. Es sagt wenig darüber, "wie es wirklich gewesen", und mehr darüber, wie diese Ordnung sprachlich konstituiert wurde, welche Metaphern sie hervorbrachte und welche Argumente im römischen Zeitdiskurs präsent waren. Wichtigstes Ziel ist die interpretatorische Erschließung der relevanten Texte und, daran anknüpfend, die Rekonstruktion des kulturellen Wissens in Bezug auf das tempus Romanum. Dieses Wissen konkretisiert sich in der (...) Darstellung der beiden Organisationsinstrumente der Zeit, Kalender und Uhr; es wird in die Kulturentstehungslehren integriert, der Kulturkritik unterworfen, für das Selbstbild Roms in Anschlag gebracht und in einem aemulatio-Verhältnis zu Griechenland und Ägypten gesehen. Interpretiert werden Texte von Plautus, Lukrez, Varro, Cicero, Caesar, Vitruv, Vergil, Livius, Ovid, Pomponius Mela, Plinius d.Ä., Sueton, Censorinus und Macrobius; ergänzend herangezogen werden motivisch relevante Passagen bei Hesiod, (Ps.-)Aischylos, Xenophon, Hekataios, Geminos, Plutarch, Iambulos, Lukian und Alkiphron.

It is becoming less and less controversial that we ought to aggressively combat climate change. One main reason for doing so is concern for future generations, as it is they who will be the most seriously affected by it. Surprisingly, none of the more prominent deontological theories of intergenerational justice can explain why it is wrong for the present generation to do very little to stop worsening the problem. This paper discusses three such theories, namely indirect reciprocity, common ownership of (...) the earth and human rights. It shows that while indirect reciprocity and common ownership are both too undemanding, the human rights approach misunderstands the nature of our intergenerational relationships, thereby capturing either too much or too little about what is problematic about climate change. The paper finally proposes a way to think about intergenerational justice that avoids the pitfalls of the traditional theories and can explain what is wrong with perpetuating climate change.

Drawing on interviews with women and men who serve on the supervisory boards of German stock-listed companies, this qualitative study examines why some female directors seek to augment gender equality in their organizations while others do not. Those who take action do so both in formal board processes and in informal settings. A sense of belonging to women as a social group and a sense of responsibility for women in the organization are key factors in explaining why some female directors (...) contribute to gender equality. In addition, the study highlights the relevance of a board culture supportive of gender equality and positive expectations by other organizational members about female directors’ role in advancing gender equality. Board chairs influence how supportive female directors perceive the organizational context to be. Where the organizational context is not seen as supportive, those who take equality-related action anyway are experienced directors. Surprisingly, the presence of other women on the board does not appear to be related to whether or not female directors take action. Examining female directors’ actions and paying close attention to both their identities and their specific organizational settings shows how the interplay between social identity and situational opportunities and constraints affects board behavior.

The agri-food system is facing a range of social-ecological threats, many of which are caused and amplified by industrial agriculture. In response, numerous sustainable agriculture narratives have emerged, proposing solutions to the challenges facing the agri-food system. One such narrative that has recently risen to prominence is regenerative agriculture. However, the drivers for the rapid emergence of regenerative agriculture are not well understood. Furthermore, its transformative potential for supporting a more sustainable agri-food system is underexplored. Through a genealogical analysis of (...) four prominent sustainable agriculture narratives; organic agriculture, conservation agriculture, sustainable intensification, and agroecology; we consider how regenerative agriculture’s growing momentum can be contextualised within existing narratives and explore the implications this might have for its transformative potential. This analysis reveals that the genealogies of these sustainable agriculture narratives have led to a number of contestations and complementarities which have coalesced to drive the emergence of regenerative agriculture. We also find that, in contrast to agroecology, regenerative agriculture shares with other Global North narratives a limited scope for offering transformative pathways for agricultural production. This is largely due to their inadequate consideration of power and equity issues in the agri-food system. We argue that regenerative agriculture therefore risks inhibiting deeper agri-food system transformations that address both social and ecological challenges and is not the unifying sustainable agriculture narrative it claims to be. Nonetheless, regenerative agriculture could contribute towards a broader plurality of sustainable agriculture narratives that collectively might enable a transformation to a more sustainable, diverse, and just agri-food system.

We investigate whether female executives influence perceived employer attractiveness for female job seekers. Drawing on signaling theory, we argue that female members in top management may signal organizational justice and organizational support and may therefore enhance perceived employer attractiveness. Findings from a scenario experiment with 357 participants indicate that female job seekers are more attracted to an organization with a female executive holding a non-stereotypical office [such as Chief Financial Officer ] as compared to an organization with an all-male top (...) management. Results of a structural equation model show that perceived organizational justice mediates the positive effect of a female holding a non-stereotypical office on perceived employer attractiveness, but perceived organizational support does not. Our results challenge the widely held view that women in top management will generally help attract female job seekers; rather, they suggest that a single female executive holding a stereotypical female office even reduces perceived employer attractiveness.

Contrary to popular belief, I argue that Leibniz is not hopelessly confused about motion: Leibniz is indeed both a relativist and an absolutist about motion, as suggested by the textual evidence, but, appearances to the contrary, this is not a problem; Leibniz’s infamous doctrine of the equivalence of hypotheses is well-supported and well-integrated within Leibniz’s physical theory; Leibniz’s assertion that the simplest hypothesis of several equivalent hypotheses can be held to be true can be explicated in such a way that (...) it makes good sense; the mere Galilean invariance of Leibniz’s conservation law does not compromise Leibniz’s relativism about motion; and Leibniz has a straightforward response to Newton’s challenge that the observable effects of the inertial forces of rotational motions empirically distinguish absolute from relative motions.

It is argued that the popular story that portrays Kant’s philosophical development as a gradual emancipation from his Leibniz-Wolffian roots that culminated in a total rejection of the Leibnizian philosophy by 1781 is not accurate. Kant’s many objections against the Leibnizian philosophy in the critical period are not directed against Leibniz himself but against the Leibniz-Wolffians. Kant considers Leibniz’s philosophy to be very close to his own, calling the Critique of Pure Reason the “true apology” of Leibniz. It is claimed (...) that this assessment is correct; the correctness is demonstrated with respect to Kant’s and Leibniz’s theories of space. (shrink)

Background: Despite the growing potential of mobile-based technologies, innovative interventions targeting the reduction of acute stress in daily life remain under-researched. Music listening is an easy-to-administer activity that is associated with lower levels of biological and self-reported stress. However, the application of music as an intervention in moments of acute stress in daily life remains to be examined. We developed a just-in-time intervention delivering music in moments of stressful experiences in daily life and tested its feasibility using a mixed methods (...) approach.Methods: In this uncontrolled pilot study, the ecological momentary music intervention was tested by 10 chronically stressed women aged 23.5 ± 3.3 years. Over 18 consecutive days, whenever participants reported stressful experiences, they were encouraged to listen to a self-compiled playlist. Subjective stress levels and saliva samples were assessed at three time points per stress report. We analyzed app-based log data, in-the-moment responses, questionnaire data, and semi-structured interview data.Results: On average, participants’ compliance with the study protocol lay at 70%. Overall, 65 stressful experiences were reported, 51 of which were followed by music listening, for an average duration of 12:53 min. Complete data were provided for 46 stressful experiences. Participants reported immediate relaxation and distraction through music listening. The interviews revealed that the intervention was easy to use and that music listening in moments of perceived stress was viewed as a new and pleasant activity. Several aspects of the protocol were identified, which should be improved in future studies.Conclusion: Since repeated stressful experiences in daily life can pose a threat to physical and mental integrity, interventions that are easily applicable and deliver support when needed most are necessary. Following minor adaptations, the EMMI can be considered as a feasible approach to target psychobiological stress responses in daily life, which is worthy of investigation in future larger-scale trials.

The view that agents are not obliged to do more than their initial fair shares when their fellow duty bearers fail to comply has prominent defenders, including Liam Murphy and David Miller. While Murphy thinks that asking agents to take up other agents’ slack would be unfair, Miller claims that slack-taking cannot be required because primary responsibility does not migrate from noncompliers to compliers. This paper argues, by contrast, that there are a number of circumstances in which there is a (...) duty to take up the slack even though it is unfair and even though responsibility stays where it is. The central claim is that what agents owe to third parties is a separate issue from how they relate to fellow duty bearers. This proposal also runs counter to familiar defenses of slack-taking that weigh its unfairness against the moral importance of the interests at stake for third parties. (shrink)

What is the wrong behind the widely criticized presentist bias of democracies? In this paper I argue that it is not that future generations are excluded from present-day democratic decision-making quite generally. Rather, I claim that due to the unique risks associated with representing future generations and the limitations on affecting future generations both institutionally and causally, the focus ought to be on including them on a more specific, narrower, set of issues, namely only those that threaten to lead to (...) their domination. I identify such issues as those that may end up being purpose-determining: that may subject future generations to previous generations’ will by forcing them to exert a substantial amount of their energies on dealing with problems caused by their predecessors. I conclude by reflecting on the extent to which political representation together with providing avenues of contestation can minimize the risk of intergenerational domination. (shrink)

The problem at the center of this essay is how one can reconcile the continuity of space with a monadological theory of matter, according to which matter is ultimately composed of simple elements, a problem that greatly exercised Leibniz, the Wolffians, and Kant. The underlying purpose of this essay is to illustrate my reading of Kant’s philosophical development, and of his relation to the Wolffians and Leibniz, according to which, (a), this development was fueled by ‘home-grown’ problems that arose within (...) the framework of the Wolffian philosophy from which Kant started out, and, (b), on his journey to critical idealism, Kant gradually moved away from Wolffianism, but closer to Leibniz, which, however, he came to realize only some years after the publication of the Critique of Pure Reason. This reading is illustrated by showing that the problem of how to reconcile the continuity of space with a monadological theory of matter is a problem that Kant inherits from Leibniz and the Wolffians, in whose thinking it already plays an important role, that Leibniz’s mature solution to the problem differs markedly from the Wolffian solution, and that Kant’s early, pre-critical solution is largely Wolffian, while his later critical solution is largely Leibnizian, as he himself notes with gleeful satisfaction. The discussion also reveals that this problem is one of the key problems that fueled Kant’s philosophical development and, eventually, led him to the discovery of transcendental idealism. (shrink)

In this article, I discuss the commemoration of public figures such as Nelson Mandela and Yitzhak Rabin. In many cases, our commemoration of such figures is based on the admiration we feel for them. However, closer inspection reveals that most (if not all) of those we currently honour do not qualify as fitting objects of admiration. Yet, we may still have the strong intuition that we ought to continue commemorating them in this way. I highlight two problems that arise here: (...) the problem that the expressed admiration does not seem appropriate with respect to the object and the problem that continued commemorative practices lead to rationality issues. In response to these issues, I suggest taking a fictionalist position with respect to commemoration. This crucially involves sharply distinguishing between commemorative and other discourses, as well as understanding the objects of our commemorative practices as fictional objects. (shrink)

Conrad Gessner was town physician and lecturer at the Zwinglian reformed lectorium in Zurich. His approach towards the world and mankind was centred on his preoccupation with the human soul, an object of study that had challenged classical writers such as Aristotle and Galen, and which remained as important in post-Reformation debate. Writing commentaries on Aristotles De Anima was part of early-modern natural philosophy education at university and formed the preparatory step for studying medicine. This article uses the case study (...) of Gessners commentary on De Anima to explore how Gessners readers prioritised De Animas information. Gessners intention was to provide the students of philosophy and medicine with the most current and comprehensive thinking. His readers responses raise questions about evolving discussions in natural philosophy and medicine that concerned the foundations of preventive healthcare on the one hand, and of anatomically specified pathological medicine on the other, and Gessners part in helping these develop.

Interactions among membrane proteins regulate numerous cellular processes, including cell growth, cell differentiation and apoptosis. We need to understand which proteins interact, where they interact and to which extent they interact. This article describes a set of novel approaches to measure, on the surface of living cells, the number of clusters of proteins, the number of proteins per cluster, the number of clusters or membrane domains that contain pairs of interacting proteins and the fraction of one protein species that interacts (...) with another protein within these domains. These data can then be interpreted in terms of the function of the protein‐protein interactions. BioEssays 26:196–203, 2004. © 2004 Wiley Periodicals, Inc. (shrink)

New forms of artificial intelligence on the one hand and the ubiquitous networking of “everything with everything” on the other hand characterize the fourth industrial revolution. This results in a changed understanding of human–machine interaction, in new models for production, in which man and machine together with virtual agents form hybrid teams. The empirical study “Socializing with robots” aims to gain insight especially into conditions of development and processes of hybrid human–machine teams. In the experiment, human–robot actions and interactions were (...) closely observed in a virtual environment. Robots as partners differed in shape and behavior. Participants were instructed to achieve an objective that could only be achieved via close teamwork. This paper unites different aspects from core disciplines of social robotics and psychology contributing to anthropomorphization with the empirical insights of the experiment. It focuses on the psychological effects on anthropomorphization and mechanization, taking the inter- and transdisciplinary field of social robotics as a starting point. (shrink)

The focus of this article is on elderly patients’ and nursing staff perceptions of privacy in the care of elderly patients/residents in five European countries. Privacy includes physical, social and informational elements. The results show that perceptions of privacy were strongest in the UK (Scotland) and weakest in Greece. Country comparisons revealed statistically significant differences between the perceptions of elderly patients and also between those of nurses working in the same ward or long-term care facility. Perceptions of privacy by patients (...) and their nursing staff were quite similar in Finland, Germany and the UK. In contrast, in Greece and Spain these perceptions were different: nurses believed that they took account of their patients’ privacy needs more often than the patients themselves felt this was the case. Among Spanish and UK patients, an association was found between lower levels of independence and comparatively less positive perceptions of privacy. No associations were established between nurses’ perceptions and their demographic factors. This is the third of a set of five articles published together in this issue of Nursing Ethics in which the results of this comparative research project are presented. (shrink)

Wittgenstein famously criticizes the philosophical practice of analyzing the meaning of words outside their ordinary use in everyday language, whereby often self-made pseudo-problems arise. In order to shed further light on Wittgenstein’s critique, this article makes use of the Remarks on the Philosophy of Psychology. First, starting from the remark in Vol. I, §52, his criticism of the philosophical method of selection and generalization is explained in detail. Next, I give a brief outline of Wittgenstein’s own way of philosophizing by (...) reference to a selection of comments concerning the use of psychological words in everyday language, which will also further elucidate his critique. Finally, I enter into the question which significance everyday language according to Wittgenstein has for philosophy. (shrink)

It is surprisingly difficult to determine what modal strength Leibniz wants to ascribe to his principle of the identity of indiscernibles (PII). I consider this question by examining (i) some direct textual evidence, (ii) Leibniz's main arguments for PII, (iii) Leibniz's presumable response to a prominent contemporary defense of the necessity of PII against Max Black style counterexamples, and (iv) Leibniz's views about the possibility of primitive haecceities. I conclude that Leibniz probably takes PII to be necessary.

This study analyses the social and political discourses related to environment and sustainable development in Costa Rica. The central interest is on those development institutions and ideologies that promote social interventions in the name of sustainable development, and on those social processes and economic relations on which the discursive formation of environment and sustainability is articulated. Four different kinds of ideologies of environmental sustainability are analysed: Environmentalism for Nature, Environmentalism for Profit, Environmentalism for the People, and Alternative Environmentalism. The study (...) highlights the complexity of political discourses that construct the relationship between nature and society, and the multiplicity of the means by which the control over natural resources, within the internally differentiated development apparatus, is defined.
