Life scientists increasingly rely upon abstraction-based modeling and reasoning strategies for understanding biological phenomena. We introduce the notion of constraint-based reasoning as a fruitful tool for conceptualizing some of these developments. One important role of mathematical abstractions is to impose formal constraints on a search space for possible hypotheses and thereby guide the search for plausible causal models. Formal constraints are, however, not only tools for biological explanations but can be explanatory by virtue of clarifying general dependency-relations and patterning between (...) functions and structures. We describe such situations as constraint-based explanations and argue that these differ from mechanistic strategies in important respects. While mechanistic explanations emphasize change-relating causal features, constraint-based explanations emphasize formal dependencies and generic organizational features that are relatively independent of lower-level changes in causal details. Our distinction between mechanistic and constraint-based explanations is pragmatically motivated by the wish to understand scientific practice. We contend that delineating the affordances and assumptions of different explanatory questions and strategies helps to clarify tensions between diverging scientific practices and the innovative potentials in their combination. Moreover, we show how constraint-based explanation integrates several features shared by otherwise different philosophical accounts of abstract explanatory strategies in biology. (shrink)

The increasing application of network models to interpret biological systems raises a number of important methodological and epistemological questions. What novel insights can network analysis provide in biology? Are network approaches an extension of or in conflict with mechanistic research strategies? When and how can network and mechanistic approaches interact in productive ways? In this paper we address these questions by focusing on how biological networks are represented and analyzed in a diverse class of case studies. Our examples span from (...) the investigation of organizational properties of biological networks using tools from graph theory to the application of dynamical systems theory to understand the behavior of complex biological systems. We show how network approaches support and extend traditional mechanistic strategies but also offer novel strategies for dealing with biological complexity. (shrink)

The U.S. National Institute of Allergies and Infectious Diseases and the National Institute of Mental Health have a new research priority: inclusion of terminally ill persons living with HIV in HIV cure-related research. For example, the Last Gift is a clinical research study at the University of California San Diego for PLWHIV who have a terminal illness, with a prognosis of less than 6 months. As end-of-life HIV cure research is relatively new, the scientific community has a timely opportunity to (...) examine the related ethical challenges. Following an extensive review of the EOL and HIV cure research ethics literature, combined with deliberation from various stakeholders and our experience with the Last Gift study to date, we outline considerations to ensure that such research with terminally ill PLWHIV remains ethical, focusing on five topics: 1) protecting autonomy through informed consent, 2) avoiding exploitation and fostering altruism, 3) maintaining a favorable benefits/risks balance, 4) safeguarding against vulnerability through patient-participant centeredness, and 5) ensuring the acceptance of next-of-kin/loved ones and community stakeholders. EOL HIV cure-related research can be performed ethically and effectively by anticipating key issues that may arise. While not unique to the fields of EOL or HIV cure-related research, the considerations highlighted can help us support a new research approach. We must honor the lives of PLWHIV whose involvement in research can provide the knowledge needed to achieve the dream of making HIV infection curable. (shrink)

There is a significant lack of diversity in philosophy, including an underrepresentation of women and people of color, and a dearth of philosophy programs that offer classes exploring philosophy outside the Western canon. This problem is further compounded by institutional racism, sexism, and ableism within philosophy pedagogy and practice and the perception that philosophy is an abstract subject suitable only for academically advanced students. If philosophy were made more accessible to a diverse group of students before they entered college, would (...) it be possible to recruit more individuals from underrepresented groups into the field? In 2018, PLATO and the APA surveyed their members about their first exposure to philosophy. It was clear that early experiences—conversations with friends and family, books in grade school, and classes in high school—were pivotal moments that generated interest in philosophy. In this paper we describe some of these experiences and suggest that P4C programs, if done well, have the potential to help build a robust and inclusive K–12 to college philosophy pipeline by tapping into the natural interest children have in philosophical wondering.

The COVID-19 pandemic posed many ethical and practical challenges for academic research. Some of these have been documented, particularly in relation to health research, but less attention has been paid to the dilemmas encountered by educational and social science research. Given that pandemics are predicted to be more frequent, it is vital to understand how to continue crucial research in schools and other learning communities. This article therefore focuses specifically on research ethics in educational and social science during the pandemic (...) of 2020–2022. The research involved interviews and workshops with University College London (UCL) academics, professional staff and graduate students and encompassed those involved in reviewing ethics applications, researchers dealing with ethics in projects that continued despite disruptions caused by COVID-19, and successful research projects specifically designed to study the effects of COVID-19 in various contexts. The article discusses some of the crucial knowledge and practical experiences that were accumulated. The operational and epistemological lessons learned from this particular institution may have wider relevance to research ethics processes in higher education environments where academics and students are grappling with post-COVID-19 ethical dilemmas and inform broader debates about how research institutions can build institutional knowledge to improve practices of ethics review at the times of health emergencies in future. Our evidence points to the significance of inter- and multidisciplinary, collaborative approaches that flatten institutional hierarchies and to the crucial role played by professional staff. In addition, we argue that ethics review processes must be underpinned by critical debates about wider issues of unequal power relationships between research partners, the nature of knowledge production, ownership and utilisation. To enhance equity and epistemic justice in research practices, ethics education should be an ongoing integral part of research ethics within research institutions. (shrink)

Experiential evidence shows that pain is associated with common meanings. These include a meaning of threat or danger, which is experienced as immediately distressing or unpleasant; cognitive meanings, which are focused on the long-term consequences of having chronic pain; and existential meanings such as hopelessness, which are more about the person with chronic pain than the pain itself. This interdisciplinary book - the second in the three-volume Meanings of Pain series edited by Dr Simon van Rysewyk - aims to better (...) understand pain by describing experiences of pain and the meanings these experiences hold for the people living through them. The lived experiences of pain described here involve various types of chronic pain, including spinal pain, labour pain, rheumatic pain, diabetic peripheral neuropathic pain, fibromyalgia, complex regional pain syndrome, endometriosis-associated pain, and cancer-related pain. Two chapters provide narrative descriptions of pain, recounted and interpreted by people with pain. Language is important to understanding the meaning of pain since it is the primary tool human beings use to manipulate meaning. As discussed in the book, linguistic meaning may hold clues to understanding some pain-related experiences, including the stigmatisation of people with pain, the dynamics of patient-clinician communication, and other issues, such as relationships between pain, public policy and the law, and attempts to develop a taxonomy of pain that is meaningful for patients. Clinical implications are described in each chapter. This book is intended for people with pain, their family members or caregivers, clinicians, researchers, advocates, and policy makers. (shrink)

_341_ _Objectives: _In patients with multivessel disease both the detection of the culprit lesion and the exact allocation are important preconditions for sufficient treatment and improved outcome. In a vessel based approach the combination of quantitative coronary angiography and fractional flow reserve measured by a pressure wire should be advantageous compared to myocardial SPECT, as morphological and functional information is delivered simultaneously. Therefore our aim was to evaluate MS in the detection and allocation of hemodynamically significant stenoses obtained by the (...) combined gold standard QCA plus FFR in patients with multivessel disease. _Methods: _FFR and QCA of 95 vessels in 80 patients have been evaluated. Hemodynamically significant target lesions were defined as intermediate stenoses between 50 and 75% with an FFR. (shrink)

Although international research is increasing in volume and importance, there remains a dearth of knowledge on similarities and differences in “national human research ethics”, that is, national ethical guidelines, Institutional Review Boards, and research stakeholder’ ethical attitudes and behaviors. We begin to address this situation by reporting upon our experiences in conducting a multinational study into the mental health of children who had a parent/carer in prison. The study was conducted in 4 countries: Germany, Great Britain, Romania, and Sweden. Data (...) on NHREs were gathered via a questionnaire survey, two ethics-related seminars, and ongoing contact between members of the research consortium. There was correspondence but even more so divergence between countries in the availability of NEGs and IRBs and in researcher’ EABs. Differences in NHREs have implications particularly in terms of harmonization but also for ethical philosophy and practice and for research integrity. (shrink)

Jones (1991) has proposed an issue-contingent model of ethical decision making by individuals in organizations. The distinguishing feature of the issue was identified as its moral intensity, which determines the moral imperative in the situation. In this study, we adapted three scenarios from the literature in order to examine the issue-contingent model. Findings, based on a student sample, suggest that (1) the perceived and actual dimensions of moral intensity often differed; (2) perceived moral intensity variables, in the aggregate, significantly (...) affected an individual''s moral judgments; and (3) some dimensions of moral intensity (namely, perceived social consensus and perceived magnitude of consequences) mattered more than others.

Persuaded by the observed positive link between the flow of appropriately skilled and trained female talent and female presence at the upper echelons of management (Plitch, Dow Jones Newswire February 9, 2005), this study has examined current trends on women’s uptake of graduate and executive education programs in the world’s top 100 business schools and explored the extent to which these business schools promote female studentship and career advancement. It contributes by providing pioneering research insight, albeit at an exploratory (...) level, into the emerging best practice on this important aspect of business school behavior, an area which is bound to become increasingly appreciated as more global economic actors wise up to the significant diseconomies inherent in the under-utilization of female talent, particularly in the developing world. Among the study’s main findings are that female graduate students averaged 30% in the sample business schools, a figure not achieved by a majority of the elite schools, including some of the highest ranked. Only 10% of these business schools have a specialist center for developing women business leaders, and only a third offered women-focused programs or executive education courses, including flextime options. A higher, and increasing, percentage of business schools, however, reported offering fellowships, scholarships or bursaries to prospective female students, and having affiliations with pro-women external organizations and networks that typically facilitate career-promoting on-campus events and activities. The implications of the foregoing are discussed, replete with a call on key stakeholder groups to more actively embrace the challenge of improving the supply of appropriately trained female talent, or top management prospects. Future research ideas are also suggested. (shrink)

This book investigates the role of inference in argumentation, considering how arguments support standpoints on the basis of different loci. The authors propose and illustrate a model for the analysis of the standpoint-argument connection, called Argumentum Model of Topics. A prominent feature of the AMT is that it distinguishes, within each and every single argumentation, between an inferential-procedural component, on which the reasoning process is based; and a material-contextual component, which anchors the argument in the interlocutors’ cultural and factual common (...) ground. The AMT explains how these components differ and how they are intertwined within each single argument. This model is introduced in Part II of the book, following a careful reconstruction of the enormously rich tradition of studies on inference in argumentation, from the antiquity to contemporary authors, without neglecting medieval and post-medieval contributions. The AMT is a contemporary model grounded in a dialogue with such tradition, whose crucial aspects are illuminated in this book. (shrink)

I argue for the view that envy and jealousy are distinct emotions, whose crucial difference is that envy involves a perception of lack while jealousy involves a perception of loss. I start by noting the common practice of using ‘envy’ and ‘jealousy’ almost interchangeably, and I contrast it with the empirical evidence that shows that envy and jealousy are distinct, albeit similar and often co-occurring, emotions. I then argue in favor of a specific way of understanding their distinction: the view (...) that envy is a response to a perceived lack of a valuable object, while jealousy is a response to a perceived loss of a valuable object. I compare such a view with the most compelling alternative theories, and show that it accounts better for paradigmatic cases. I conclude by showing how the lack vs. loss model can handle complications: ambiguous cases, that is, when it is epistemically unclear whether one experiences lack or loss; hybrid cases, that is, when one seems to experience both lack and loss; and borderline cases, that is, when it is metaphysically unclear whether one experiences lack or loss.

This paper argues that so-called “trumping preemption” is in fact overdetermination or early preemption, and is thus not a distinctive form of redundant causation. I draw a novel lesson from cases thought to be trumping: that the boundary between preemption and overdetermination should be reconsidered.

In this paper, I ask whether there is a defensible philosophical view according to which everybody is beautiful. I review two purely aesthetical versions of this claim. The No Standards View claims that everybody is maximally and equally beautiful. The Multiple Standards View encourages us to widen our standards of beauty. I argue that both approaches are problematic. The former fails to be aspirational and empowering, while the latter fails to be sufficiently inclusive. I conclude by presenting a hybrid ethical–aesthetical (...) view according to which everybody is beautiful in the sense that everybody can be perceived through a loving gaze. I show that this view is inclusive, aspirational and empowering, and authentically aesthetical. (shrink)

In this book , Lorraine Besser-Jones develops a eudaimonistic virtue ethics based on a psychological account of human nature. While her project maintains the fundamental features of the eudaimonistic virtue ethical framework—virtue, character, and well-being—she constructs these concepts from an empirical basis, drawing support from the psychological fields of self-determination and self-regulation theory. Besser-Jones’s resulting account of "eudaimonic ethics" presents a compelling normative theory and offers insight into what is involved in being a virtuous person and "acting well." (...) This original contribution to contemporary ethics and moral psychology puts forward a provocative hypothesis of what an empirically-based moral theory would look like. (shrink)

In recent years, the philosophical focus of the modeling literature has shifted from descriptions of general properties of models to an interest in different model functions. It has been argued that the diversity of models and their correspondingly different epistemic goals are important for developing intelligible scientific theories. However, more knowledge is needed on how a combination of different epistemic means can generate and stabilize new entities in science. This paper will draw on Rheinberger’s practice-oriented account of knowledge production. The (...) conceptual repertoire of Rheinberger’s historical epistemology offers important insights for an analysis of the modelling practice. I illustrate this with a case study on network modeling in systems biology where engineering approaches are applied to the study of biological systems. I shall argue that the use of multiple means of representations is an essential part of the dynamic of knowledge generation. It is because of – rather than in spite of – the diversity of constraints of different models that the interlocking use of different epistemic means creates a potential for knowledge production.

With the emergence of systems biology the notion of organizing principles is being highlighted as a key research aim. Researchers attempt to ‘reverse engineer’ the functional organization of biological systems using methodologies from mathematics, engineering and computer science while taking advantage of data produced by new experimental techniques. While systems biology is a relatively new approach, the quest for general principles of biological organization dates back to systems theoretic approaches in early and mid-20th century. The aim of this paper is (...) to draw on this historical background in order to increase the understanding of the motivation behind the systems theoretic approach and to clarify different epistemic aims within systems biology. We pinpoint key aspects of earlier approaches that also underlie the current practice. These are i) the focus on relational and system-level properties, ii) the inherent critique of reductionism and fragmentation of knowledge resulting from overspecialization, and iii) the insight that the ideal of formulating abstract organizing principles is complementary to, rather than conflicting with, the aim of formulating detailed explanations of biological mechanisms. We argue that looking back not only helps us understand the current practice but also points to possible future directions for systems biology. (shrink)

The starting point of this paper is the acknowledgement that individual reasoning, understood as inner dialogue, and social argumentation, albeit they are two different phenomena, share some similarities. On this basis, this paper sets out to apply instruments from argumentation theory to inner dialogue in order to better explain it. Within this framework, some limitations to the study of inner dialogue are also discussed; and methodological suggestions are provided in order to grasp what could be considered data on “inner dialogue” (...) starting from social research interviews. The ultimate aim is to go beyond a mere recognition of a similarity between inner dialogue and argumentation and start analysing inner dialogue empirically using tools from argumentation theory. The findings show that the analytic overview help shed light on how inner dialogue within processes of individual decision-making develops and what it means to have an internal difference of opinion, in which one and the same person adopts opposing standpoints and argues for them. On the opposite, it is shown that the notion of strategic manoeuvring per se cannot be applied to inner dialogue. (shrink)

This paper argues that scale-dependence of physical and biological processes offers resistance to reductionism and has implications that support a specific kind of downward causation. I demonstrate how insights from multiscale modeling can provide a concrete mathematical interpretation of downward causation as boundary conditions for models used to represent processes at lower scales. The autonomy and role of macroscale parameters and higher-level constraints are illustrated through examples of multiscale modeling in physics, developmental biology, and systems biology. Drawing on these examples, (...) I defend the explanatory importance of constraining relations for understanding the behavior of biological systems. (shrink)

We argue that in implanted neurotechnology research, participants and researchers experience what Henry Richardson has called “moral entanglement.” Participants partially entrust researchers with access to their brains and thus to information that would otherwise be private, leading to created intimacies and special obligations of beneficence for researchers and research funding agencies. One of these obligations, we argue, is about continued access to beneficial technology once a trial ends. We make the case for moral entanglement in this context through exploration of (...) participants’ vulnerability, uncompensated risks and burdens, depth of relationship with the research team, and dependence on researchers in implanted neurotechnology trials.

Adaptationism has for decades been the topic of sophisticated debates in philosophy of biology but methodological adaptationism has not received as much attention as the empirical and explanatory issues. In addition, adaptationism has mainly been discussed in the context of evolutionary biology and not in fields such as zoophysiology and systems biology where this heuristic is also used in design analyses of physiological traits and molecular structures. This paper draws on case studies from these fields to discuss the productive and (...) problematic aspects of this heuristic in different research practices, in functional as well as evolutionary studies on different levels of biological organization. Gould and Lewontin’s Spandrels-paper famously criticized adaptationist methodology for implying the risk of generating ‘blind spots’ with respect to non-selective effects on evolution. Some have claimed that this bias can be accommodated through the testing of evolutionary hypotheses. Although this is an important aspect of overcoming naïve adaptationism, I argue that the issue of methodological biases is broader than the question of testability. I demonstrate the productivity of adaptationist heuristics but also discuss the deeper problematic aspects associated with the methodological imperialism that is part of the strong adaptationist position.

Can we love and envy the same person at the same time? There is an overwhelming, cross-cultural and cross-disciplinary, consensus that love and envy are deeply incompatible. In this paper, I challenge this consensus, and focus in particular on the normative thesis that true love should be void of envy proper. I first propose an indirect argument. Because love and envy thrive in the same psychological conditions, it is not unlikely to feel envy toward the beloved. If we want ideals (...) that do not go against our psychological propensities, then we should not aim for a love that is wholly void of envy. I then propose a direct argument, in defense of two positive ideals. I argue that a certain kind of envy—emulative envy—can be beneficial to the loving relationship; in turn, a certain kind of love—wise love— which accepts the presence of envy, can be beneficial to our lives. Thus, that love and envy are so linked in our psychology is not something that we should merely tolerate, but wholeheartedly embrace. (shrink)

This paper presents preliminary findings of the project [name omitted for anonymity]. This interdisciplinary project builds on Argumentation theory and developmental sociocultural psychology for the study of children’s argumentation. We reconstruct children’s inferences in adult-child and child-child dialogical interaction in conversation in different settings. We focus in particular on implicit premises using the Argumentum Model of Topics for the reconstruction of the inferential configuration of arguments. Our findings reveal that sources of misunderstandings are more often than not due to misalignments (...) of implicit premises between adults and children; these misalignments concern material premises rather than the inferential-procedural level.

At the beginning of Being and Time, Heidegger rejects Husserl’s classical phenomenology on three grounds: he claims that Husserlian phenomenology is impaired by indeterminate concepts, by naïve personalism, and by obscurities in its account of individuation. The paper studies the validity of this early critique by explicating Husserl’s discourse on human persons as bodily-spiritual beings and by clarifying his account of the principles by which such beings can be individuated. The paper offers three types of considerations. After a summary of (...) Heidegger’s early critique of Husserl, the second section of the paper distinguishes between two dimensions of Husserl’s discourse on human persons. It argues that Husserl does not put forward one analysis of the being of humans, but explicates two different accounts and then studies critically their mutual relations of dependency: on the one hand, the naturalistic account of human beings as layered beings and on the other hand the personalistic account of human beings as peculiar kinds of unified wholes in which the mental and the bodily are inextricably intertwined. The third section of the paper clarifies Husserl’s theory of individuation and its consequences for our discourse on human persons. Finally, the fourth section explicates the conceptual means by which Husserl develops his account of human beings as persons. The paper ends in drawing some conclusions for contemporary philosophical anthropology. (shrink)

This paper throws some light on the nature of argumentation, its use and advantages, within the setting of doctor–patient interaction. It claims that argumentation can be used by doctors to offer patients reasons that work as ontological conditions for enhancing the decision making process, as well as to preserve the institutional nature of their relationship with patients. In support of these claims, selected arguments from real-life interactions are presented in the second part of the paper, and analysed by means of (...) a model of argumentation borrowed from classical rhetoric, and refined according to the modern orientation of the pragma-dialectic approach.

The importance of the hidden curriculum is recognised as a practical training ground for the absorption of medical ethics by healthcare professionals. Pakistan’s healthcare sector is hampered by the exclusion of ethics from medical and nursing education curricula and the absence of monitoring of ethical violations in the clinical setting. Nurses have significant knowledge of the hidden curriculum taught during clinical practice, due to long working hours in the clinic and front-line interaction with patients and other practitioners.

A remarkable thing about natural language is that we can use it to share our beliefs and thoughts about the world with other speakers of our language. In cases of successful communication, beliefs seem to be transferred from speakers to hearers by means of the hearer recovering the contents of the speaker’s utterances. This is so natural to us that we take it for granted in our everyday life, and rarely stop to think about how it's is possible. Nevertheless, it's (...) a phenomenon that calls for explanation. It is natural to expect that natural language semantics has a key explanatory role to play here. In order to understand this role, we must relate the semantic values assigned to sentences by semantic theory with the content of our speech acts. The simplest possible relation would be identity; the meaning of a sentence is simply the belief expressed by an assertion of the sentence in a given context of utterance. However, a number of problem cases in the literature suggest that this cannot be the case. This dissertation offers a critical assessment of the arguments for distinguishing the semantic value of a sentence from it's so called assertoric content, focusing on problems arising from the analysis of tense and temporal expressions. I conclude that they are indeed distinct, and offer a constructive account of how they must be related in order to allow for an explanation of communicative success. (shrink)

Creativity is an important quality that has been linked with problem solving, achievement, and scientific advancement. It has previously been proposed that creative individuals pay greater attention to and are able to utilize information that others may consider irrelevant, in order to generate creative ideas (e.g., Eysenck, 1995). In this study we investigated whether there was a relationship between creativity and greater learning about irrelevant information. To answer this question, we used a self-report measure of creative ideation and a blocking (...) task, which involved learning about irrelevant stimuli. We failed to find evidence for this association, with a Bayes Factor indicating support for no relationship between these measures. While it is possible that a different measure of creative ideation, for example one which does not rely on self-report, may produce different results, a more lucrative research direction may be focusing on the link between creativity and cognitive flexibility, in line with suggestions by Zabelina and Robinson (2010).

A case study in the kinds of problems to expect from this increasingly popular marketing tactic.

ABSTRACTThis paper begins with the assumption that it is morally problematic when people in need are offered money in exchange for research participation if the amount offered is unfair. Such offers are called ‘coercive’, and the degree of coerciveness is determined by the offer's potential to cause exploitation and its irresistibility. Depending on what view we take on the possibility to compensate for the sacrifices made by research participants, a wish to avoid ‘coercive offers’ leads to policy recommendations concerning payment (...) for participation. For sacrifices considered compensable, we ought to offer either no payment or payment at a level deemed fair, while for sacrifices deemed incompensable, we always ought to offer no payment because as compensation appears and increases, so too does coercion. This article provides a model for thinking of the way in which degrees of exploitativeness, irresistibility, and coerciveness interact with the size of the reward for compensable and incompensable cases.

Formal dialogue systems model rule-based interaction between agents and as such have multiple applications in multi-agent systems and AI more generally. Their conceptual roots are in formal theories of natural argumentation, of which Hamblin’s formal systems of argumentation in Hamblin (Fallacies. Methuen, London, 1970, Theoria 37:130–135, 1971) are some of the earliest examples. Hamblin cites the medieval theory of obligationes as inspiration for his development of formal argumentation. In an obligatio, two agents, the Opponent and the Respondent, engage in an (...) alternating-move dialogue, where the Respondent’s actions are governed by certain rules, and the goal of the dialogue is establishing the consistency of a proposition. We implement obligationes in the formal dialogue system framework of Prakken (Knowl Eng Rev 21(2):163–188, 2006) using Dynamic Epistemic Logic (van Ditmarsch et al. in Dynamic epistemic logic, Synthese Library Series. Springer, Berlin, 2007). The result is a new type of inter-agent dialogue, for consistency-checking, and analyzing obligationes in this way also sheds light on interpretational and historical questions concerning their use and purpose in medieval academia.

The politics of populism is the politics of belonging. It reflects a deep challenge to the liberal democratic state, which attempts to maintain social boundaries (as an imperative of state capacity) but also allow immigration. Boundaries—established through citizenship and norms of belonging—must be both coherent and malleable. Changes to boundaries become sites of contestation for exclusionary populists in the putative interest of “legitimate” citizens. Populism is an inevitable response to liberal democratic adjustment; any liberal democracy that redefines citizenship opens itself (...) to populist challenge. (shrink)

Why do I have to be ethical? That is the essential question of a logical foundation of ethics in the phenomenology of Edmund Husserl. This article proposes to see the basic motivation of an ethical reason in the relationship between the two fundamental poles, that is the «Lifeworld» («Lebenswelt») and the «I-subject» («Ich-Subjekt»). This connection will be considered to constitute ethics in this article. This kind of ethics as a «condition of possibility» is then an a-priori ontological necessity. The article (...) will demonstrate how the composition of Husserl’s Prolegomena and his argumentation are an example of a foundation for phenomenological ethics: in this book Husserl derived logic as the first «condition of possibility». With logic’s three main characteristics — theory, normativity and praxis — it is the theoretical basis of a phenomenological ethics. (shrink)
