This expository paper presents an application, to the modal logic S4, of the valuation semantics technique proposed by Loparić for the basic normal modal logic K. In previous works we presented a valuation semantics for the minimal temporal logic Kt and several other systems modal and temporal logic. How to deal with S4, however, was left as an open problem—although we arrived at a working definition of \(A_1,\ldots,A_n\) -valuations, we were not able to prove an important lemma for correctness. In (...) this paper we solve this, presenting valuations for S4. (shrink)

In this paper, we present valuation semantics for the Propositional Intuitionistic Calculus (also called Heyting Calculus) and three important subcalculi: the Implicative, the Positive and the Minimal Calculus (also known as Kolmogoroff or Johansson Calculus). Algorithms based in our definitions yields decision methods for these calculi. DOI:10.5007/1808-1711.2010v14n1p125.

One of the oldest systems of paraconsistent logic is the set of so-called C-systems of Newton da Costa, and this has been generalized into a family of systems now known as logics of formal inconsistencies by Walter Carnielli, Marcelo Coniglio and João Marcos. The characteristic notion in these systems is the so-called consistency operator which, roughly speaking, indicates how gluts are behaving. One natural question then is to ask if we can let not only gluts but also gaps be around (...) and generalize the notion of consistency into classicality. This is already considered by Andréa Loparić and da Costa in the style of C-systems. The aim of this paper is to develop a family of systems that generalizes the system of Loparić and da Costa which may be called logics of formal classicality. (shrink)

Background Gerontechnologies are increasingly used in the care for older people. Many studies on their acceptability and ethical implications are conducted, but mainly from the perspective of principlism. This narrows our ethical gaze on the implications the use of these technologies have. Research question How do participants speak about the impact that gerontechnologies have on the different phases of care, and care as a process? What are the moral implications from an ethic of care perspective? Research design Secondary analysis of (...) semi-structure interviews, whose segments on specific technologies were analysed through reflexive thematic analysis. Participants and research context Sixty-seven Swiss stakeholders involved in the use of gerontechnologies, including professional caregivers, informal caregivers, and older persons themselves. Ethical considerations The research study was evaluated by the Ethics Commission of Northwest and Central Switzerland (EKNZ). All participants received an information document before the interview date detailing the purpose, procedure, and anonymization measures. After explaining the study during the agreed upon interview time and upon receiving their written informed consent, the interview process began. Findings/results Four themes are identified: Identifying care needs, Taking responsibility, Hands-on work, Responding to care. As part of these themes, many codes highlighting the ambivalent impact of gerontechnologies are created, ranging from ‘Expanded capacity for…identifying care needs’ to ‘Create new & (un)necessary…hands-on work’. The moral implications of these results from the care ethics perspective are discussed, through the ethical elements of: attentiveness, responsibility, competence, and responsiveness. Conclusions The moral implications of gerontechnologies on care phases from the care ethics perspective open up several questions on whether they actually help give care a central role in social life and provide more competent care.

Logical form has always been a prime concern for philosophers belonging to the analytic tradition. For at least one century, the study of logical form has been widely adopted as a method of investigation, relying on its capacity to reveal the structure of thoughts or the constitution of facts. This book focuses on the very idea of logical form, which is directly relevant to any principled reflection on that method. Its central thesis is that there is no such thing as (...) a correct answer to the question of what is logical form: two significantly different notions of logical form are needed to fulfil two major theoretical roles that pertain respectively to logic and to semantics. This thesis has a negative and a positive side. The negative side is that a deeply rooted presumption about logical form turns out to be overly optimistic: there is no unique notion of logical form that can play both roles. The positive side is that the distinction between two notions of logical form, once properly spelled out, sheds light on some fundamental issues concerning the relation between logic and language.

.This paper discusses Aristotle’s thesis and Boethius’ thesis, the most distinctive theorems of connexive logic. Its aim is to show that, although there is something plausible in Aristotle’s thesis and Boethius’ thesis, the intuitions that may be invoked to motivate them are consistent with any account of indicative conditionals that validates a suitably restricted version of them. In particular, these intuitions are consistent with the view that indicative conditionals are adequately formalized as strict conditionals.

Citizen science models of public participation in scientific research represent a growing area of opportunity for health and biomedical research, as well as new impetus for more collaborative forms of engagement in large-scale research. However, this also surfaces a variety of ethical issues that both fall outside of and build upon the standard human subjects concerns in bioethics. This article provides background on citizen science, examples of current projects in the field, and discussion of established and emerging ethical issues for (...) citizen science in health and biomedical research.

The possibility of extraterrestrial intelligence (ETI) exists despite no observed evidence, and the risks and benefits of actively searching for ETI (Active SETI) have been debated. Active SETI has been criticized for potentially exposing humanity to existential risk, and a recent game-theoretical model highlights the Hobbesian trap that could occur following contact if mutual distrust leads to mutual destruction. We argue that observing a nearby ETI would suggest the existence of many unobserved ETI. This would expand the game and implies (...) that there may be a mechanism that prevents ETI from attacking us. As a result, the Hobbesian trap would be avoided if both parties assumed the other is not likely to attack. (shrink)

In the intriguing article The puzzle of the changing past, Barlassina and Del Prete argue that, if one grants a platitude about truth and accepts a simple story that they tell, one is forced to conclude that the past has changed. I will suggest that there is a coherent way to resist that conclusion. The platitude about truth is in fact a platitude, but the story is not exactly as they tell it.

According to a widespread view, a complete explanatory reduction of all aspects of the human mind to the electro-chemical functioning of the brain is at hand and will certainly produce vast and positive cultural, political and social consequences. However, notwithstanding the astonishing advances generated by the neurosciences in recent years for our understanding of the mechanisms and functions of the brain, the application of these findings to the specific but crucial issue of human agency can be considered a “pre-paradigmatic science” (...) (in Thomas Kuhn’s sense). This implies that the situation is, at the same time, intellectually stimulating and methodologically confused. More specifically—because of the lack of a solid, unitary and coherent methodological framework as to how to connect neurophysiology and agency—it frequently happens that tentative approaches, bold but very preliminary claims and even clearly flawed interpretations of experimental data are taken for granted. In this article some examples of such conceptual confusions and intellectual hubris will be presented, which derive from the most recent literature at the intersection between neurosciences, on the one hand, and philosophy, politics and social sciences, on the other hand. It will also be argued that, in some of these cases, hasty and over-ambitious conclusions may produce negative social and political consequences. The general upshot will be that very much has still to be clarified as to what and how neurosciences can tell us about human agency and that, in the meantime, intellectual and methodological caution is to be recommended.

Organoids are three-dimensional biological structures grown in vitro from different kinds of stem cells that self-organise mimicking real organs with organ-specific cell types. Recently, researchers have managed to produce human organoids which have structural and functional properties very similar to those of different organs, such as the retina, the intestines, the kidneys, the pancreas, the liver and the inner ear. Organoids are considered a great resource for biomedical research, as they allow for a detailed study of the development and pathologies (...) of human cells; they also make it possible to test new molecules on human tissue. Furthermore, organoids have helped research take a step forward in the field of personalised medicine and transplants. However, some ethical issues have arisen concerning the origin of the cells that are used to produce organoids and their properties. In particular, there are new, relevant and so-far overlooked ethical questions concerning cerebral organoids. Scientists have created so-called mini-brains as developed as a few-months-old fetus, albeit smaller and with many structural and functional differences. However, cerebral organoids exhibit neural connections and electrical activity, raising the question whether they are or will one day be somewhat sentient. In principle, this can be measured with some techniques that are already available, which are used for brain-injured non-communicating patients. If brain organoids were to show a glimpse of sensibility, an ethical discussion on their use in clinical research and practice would be necessary. (shrink)

The paper discusses an objection, put forward by - among others - John McDowell, to Kripke’s Wittgenstein’s non-factualist and relativist view of semantic discourse. The objection goes roughly as follows: while it is usually possible to be a relativist about a given domain of discourse without being a relativist about anything else, relativism about semantic discourse entails global relativism, which in turn entails subjective idealism, which we can reasonably assume to be false. The paper’s first section sketches Kripke’s Wittgenstein’s ideas (...) about semantic discourse and gives a fully explicit formulation of the objection. The second section describes and briefly discusses the formal apparatus needed to evaluate the objection - which is basically equivalent to John MacFarlane’s recent development of David Kaplan’s classic semantic framework. Finally, the third section explains in detail why the objection fails. I show that even though relativism about semantic discourse does entail a form of global relativism, the relativism in question does not entail anything like Berkeleyan or Fichtean idealism. This particular kind of relativism holds that which character (in Kaplan’s sense) is associated to a given utterance depends on what MacFarlane calls “the context of assessment”. (shrink)

Current debates on collective intentionality focus on the cognitive capacities, attitudes, and mental states that enable individuals to take part in joint actions. It is typically assumed that collective intentionality is a capacity which is added to other, pre-existing, capacities of an individual and is exercised in cooperative activities like carrying a table or painting a house together. We call this the additive account because it portrays collective intentionality as a capacity that an individual possesses in addition to her capacity (...) for individual intentionality. We offer an alternative view according to which the primary entity to which collective intentionality has to be ascribed is not the human individual, but a “form of life.” As a feature of a form of life, collective intentionality is something more than the specific capacity exercised by an individual when she cooperates with others. Collective intentionality transforms all the capacities of the bearers of this specific form of life. We thus call our proposal the transformative account of collective intentionality. (shrink)

Perceptions of a firm’s stance on corporate social responsibility (CSR) are influenced by its corporate marketing efforts including branding, reputation building, and communications. The current research examines CSR from the consumer’s perspective, focusing on antecedents and consequences of perceived CSR. The findings strongly support the fact that particular cues, namely perceived financial performance and perceived quality of ethics statements, influence perceived CSR which in turn impacts perceptions of corporate reputation, consumer trust, and loyalty. Both consumer trust and loyalty were also (...) found to reduce the perceived risk that consumers experience in buying and using products. From these significant findings, we draw several conclusions and implications, including the importance of enhancing firm focus toward its ethical commitment and long-term reputation. (shrink)

Modern zoos strive to educate visitors about zoo animals and their wild counterparts’ conservation needs while fostering appreciation for wildlife in general. This research review examines how zoos influence those who visit them. Much of the research to-date examines zoo visitors’ behaviors and perceptions in relation to specific exhibits, animals and/or programs. In general, visitors have more positive perceptions and behaviors about zoos, their animals and conservation initiatives the more they interact with animals, naturalistic exhibits, and zoo programming/staff. Furthermore, zoo (...) visitors are receptive to conservation messaging and initiatives at zoos, and are more likely to participate in on-site conservation opportunities as opposed to after their visits. The research also suggests that repeat visitors are even more inclined to seek out conservation efforts compared to those visiting zoos for the first time. While current research suggests that repeat-visitors are more likely to engage in conservation efforts, little is known about causal factors related to such findings, and almost no research exists to-date comparing the conservation efforts of visitors vs. non-visitors. This latter comparison will likely play a greater role in future zoo visitor research, since it poses one of the most important metrics for evaluating the specific effects visiting a zoo can have on people engaging in conservation efforts in general.

Anecdotal evidence has long lamented the status of social studies in elementary classrooms as observed by preservice teachers. As standardized testing has risen for mathematics and language arts, social studies has been pushed aside. In the aftermath of accountability legislation such as No Child Left Behind, research indicates that social studies is less visible in elementary classrooms due to an instructional focus on tested content areas (e.g. math, language arts, reading). In this study, approximately 90 elementary preservice teachers enrolled in (...) a social studies methods course responded to a survey and indicated the frequency and quality of lessons they observed over the course of a single semester. Findings report that preservice elementary teachers witnessed few, if any, lessons in social studies in the elementary classroom. Implications for teacher education are discussed. (shrink)

A widely accepted claim about counterfactuals is that they differ from strict conditionals, that is, there is no adequate representation of them as sentences of the form   . To justify this claim, Stalnaker and Lewis have argued that some fallacious inferences would turn out valid if counterfactuals were so represented. However, their argument has a flaw, as it rests on a questionable assumption about the relation between surface grammar and logical form. Without that assumption, no consequence of the (...) alleged kind is obtained, hence the claim may be rejected. (shrink)

This book offers a comprehensive account of vitalism and the Romantic philosophy of nature. The author explores the rise of biology as a unified science in Germany by reconstructing the history of the notion of “vital force,” starting from the mid-eighteenth through the early nineteenth century. Further, he argues that Romantic Naturphilosophie played a crucial role in the rise of biology in Germany, especially thanks to its treatment of teleology. In fact, both post-Kantian philosophers and naturalists were guided by teleological (...) principles in defining the object of biological research. The book begins by considering the problem of generation, focusing on the debate over the notion of “formative force.” Readers are invited to engage with the epistemological status of this formative force, i.e. the question of the principle behind organization. The second chapter provides a reconstruction of the physiology of vital forces as it was elaborated in the mid- to late-eighteenth century by the group of physicians and naturalists known as the “Göttingen School.” Readers are shown how these authors developed an understanding of the animal kingdom as a graded series of organisms with increasing functional complexity. Chapter three tracks the development of such framework in Romantic Naturphilosophie. The author introduces the reader to the problem of classification, showing how Romantic philosophers of nature regarded classification as articulated by a unified plan that connects all living forms with one another, relying on the idea of living nature as a universal organism. In the closing chapter, this analysis shows how the three instances of pre-biological discourse on living beings – theory of generation, physiology and natural history – converged to form the consolidated disciplinary matrix of a general biology. The book offers an insightful read for all scholars interested in classical German philosophy, especially those researching the philosophy of nature, as well as the history and philosophy of biology.

This paper outlines a truth-conditional view of logical form, that is, a view according to which logical form is essentially a matter of truth-conditions. The main motivation for the view is a fact that seems crucial to logic. As _§_1 suggests, fundamental logical relations such as entailment or contradiction can formally be explained only if truth-conditions are formally represented.§2 spells out the view. _§_3 dwells on its anity with a conception of logical form that has been defended in the past.

Is logic masculine? Is women's lack of interest in the "hard core" philosophical disciplines of formal logic and semantics symptomatic of an inadequacy linked to sex? Is the failure of women to excel in pure mathematics and mathematical science a function of their inability to think rationally? Andrea Nye undermines the assumptions that inform these questions, assumptions such as: logic is unitary, logic is independenet of concrete human relations, and logic transcends historical circumstances as well as gender. In a (...) series of studies of the logics of historical figures--Parmenides, Plato, Aristotle, Zeno, Abelard, Ockham, and Frege--she traces the changing interrelationships between logical innovation and oppressive speech strategies, showing that logic is not transcendent truth but abstract forms of language spoken by men, whether Greek ruling citizens, or scientists.

Moral bioenhancement is the attempt to improve human behavioral dispositions, especially in relation to the great ethical challenges of our age. To this end, scientists have hypothesised new molecules or even permanent changes in the genetic makeup to achieve such moral bioenhancement. The philosophical debate has focused on the permissibility and desirability of that enhancement and the possibility of making it mandatory, given the positive result that would follow. However, there might be another way to enhance the overall moral behavior (...) of us humans, namely that of targeting people with lower propensity to trust and altruism. Based on the theory of attachment, people who have a pattern of insecure attachment are less inclined to prosocial behavior. We know that these people are influenced by negative childhood memories: this negative emotional component may be erased or reduced by the administration of propranolol when the bad memory is reactivated, thereby improving prosocial skills. It could be objected that memory-editing might be a threat for the person’s identity and authenticity. However, if the notion of rigid identity is replaced by that of extended identity, this objection loses validity. If identity is understood as something that changes over time, moral bioenhancement through memory-editing seems indeed legitimate and even desirable. (shrink)

Hospital ethics committees (HECs) and ethicists generally describe themselves as engaged in four domains of practice: case consultation, research, education, and policy work. Despite the increasing attention to quality indicators, practice standards, and evaluation methods for the other domains, comparatively little is known or published about the policy work of HECs or ethicists. This article attempts to open the ?black box? of this health care ethics practice by providing two detailed case examples of ethics policy reviews. We also describe the (...) development and application of an evaluation strategy to assess the quality of ethics policy review work, and to enable continuous improvement of ethics policy review processes. Given the potential for policy work to impact entire patient populations and organizational systems, it is imperative that HECs and ethicists develop clearer roles, responsibilities, procedural standards, and evaluation methods to ensure the delivery of consistent, relevant, and high-quality ethics policy reviews.

In his interesting commentary, Joshua Shepherd raises two points—one related to epistemology, the other to ethics—about our article on human cerebral organoids.1 2 From the epistemological standpoint, he calls into question the need for a theory of consciousness. A theory of consciousness, for him, is not necessary because of the lack of consensus about the very nature of consciousness. Shepherd suggests that ‘given widespread disagreement, applying a theory of consciousness may not be helpful when attempting to diagnose the presence of (...) consciousness in cerebral organoids’. In Shepherd’s view, it would be better to transfer ‘concepts already under development in work on the presence and structure of consciousness in difficult marginal cases involving traumatic brain injury’.2 We could not agree more on this last point; detecting a minimal capacity for consciousness in the brain of comatose patients is a very similar challenge to inferring the presence of consciousness in cerebral organoids. Every day, as a by-product of saving many lives, intensive care medicine artificially produces thousands of brains that may remain isolated, split or fragmented; in the worst case, cortical islands, or an archipelago of islands, may survive while being disconnected from the outside world. Can these islands host some form of consciousness? That is, does it feel like anything to be a large piece of human cortex? Addressing this difficult question requires the development of general, objective brain-based indices of consciousness that are independent of sensory processing, executive functions and motor outputs.3 Consider, for example, a patient showing reflexive spontaneous behaviour, no response to command and no ability to communicate. In her brain, afferent pathways are damaged, thereby impairing the recruitment of cortical areas in response to sensory stimulation; basal ganglia, as well as other frontal structures supporting executive functions, are impaired. However, resting metabolism and significant electroencephalography …. (shrink)

Though widely derided by popular psychologists and self-help writers as an emotionally toxic and destructive response, blame has many defenders among contemporary moral philosophers. Blaming wrongdoers has been thought to express deep commitment to moral values and norms, to be intimately bound up with practices of holding others responsible, and to be an important exercise of moral agency. In this paper I push against the grain of such defenses of blame just enough to articulate what seems right in the more (...) popular lines of critique. I distinguish between blame as a reactive attitude and blaming as a speech act, and argue that some disagreement over the value of blame can be explained by the fact that blaming, as a speech act, takes several distinct forms. Critiques of blame, I suggest, properly target what we might call judgmental or strongly verdictive blaming, the sort of blaming that passes judgment on the wrongdoer him- or herself, and treats him or her as deserving of the blamer’s hostile or “punishing” reactions. This kind of blaming, I argue, tends to foreclose engagement in further moral dialogue with wrongdoers, an effect that is particularly destructive in therapeutic contexts. In such contexts, it is often more appropriate—and more constructive—to hold others answerable without blaming them in the strongly verdictive sense. I argue, moreover, that strongly verdictive blame may be similarly destructive outside of straightforwardly therapeutic contexts, and I challenge the idea that there is in any case a sharp or clear dividing line between therapeutic and non-therapeutic responses to wrongdoers. Holding answerable in a non-judgmental mode is a response that may have a therapeutic dimension, but it nonetheless engages a wrongdoer as a moral peer and partner in moral dialogue. This account of non-judgmental answerability, I suggest, captures much of what moral philosophers have taken to be valuable about blame, while accommodating the insights of those who criticize its more toxic forms.

A comparison of two groups of college students, at a public state university and a private religious school, yields the same results: undergraduates’ interpretations of recent business scandals make distinctions between public and private behavior. Students admire “family men” even when they are caught at fraud.

Most leadership theories, including stakeholder theories, do not address this disjunction. This (...) article describes the phenomenon and maps the ethics literature to locate the dynamic forces underlying the empirical and theoretical disconnections between leadership and ethics.

Chapter 14. Andrea Timár engages with literary representations of the experience of perpetrators of dehumanization. Her chapter focuses on perpetrators of dehumanization who do not violate laws of their society (i.e., they are not criminals) but exemplify what Simona Forti, inspired by Hannah Arendt, calls “the normality of evil.” Through the parallel examples of Dezső Kosztolányi’s Anna Édes (1926) and Doris Lessing’s The Grass is Singing (1950), Timár first explores a possible clash between criminals and perpetrators of dehumanization, showing (...) literature’s exceptional ability to reveal the gap between ethics and law. Second, she examines novels focalized through perpetrators and the difficult narrative empathy they provoke, arguing that only the critical reading of these novels can make one engage with the potential perpetrator in oneself. As case studies, Timár examines Daniel Defoe’s Robinson Crusoe (1719), which may potentially turn its reader into an accomplice in the process of dehumanization, and J.M. Coetzee’s Foe (1986), which puts on critical display the dehumanizing potentials of both aesthetic representation and sympathy as imaginative violence. Third, she reads Jonathan Littell’s The Kindly Ones [Les Bienveillantes, 2006], which can make the reader question, through the polyphony of the voice of its protagonist, the notions of narrative voice and readerly empathy, only to reveal that the difficulty involved in empathizing with perpetrator characters lies not so much in the characters’ being perpetrators, but rather in their being literary characters. Eventually, Timár briefly touches upon the problem of the aesthetic and the comic via Nabokov’s Lolita (1955) to ask whether one can avoid some necessarily dehumanizing aspects of humor. (shrink)
