A topological class logic is an infinitary logic formed by combining a first-order logic with the quantifier symbols O and C. The meaning of a formula closed by quantifier O is that the set defined by the formula is open. Similarly, a formula closed by quantifier C means that the set is closed. The corresponding models are a topological class spaces introduced by Ćirić and Mijajlović (Math Bakanica 1990). The completeness theorem is proved.

Because spaying/neutering animals involves the harming of some animals in order to prevent harm to others, some ethicists, like David Boonin, argue that the philosophy of animal rights is committed to the view that spaying/neutering animals violates the respect principle and that Trap Neuter Release programs are thus impermissible. In response, I demonstrate that the philosophy of animal rights holds that, under certain conditions, it is justified, and sometimes even obligatory, to cause harm to some animals in order to prevent (...) greater harm to others. As I will argue, causing lesser harm to some animals in order to prevent greater harm to others, as TNR programs do, is compatible with the recognition of the inherent value of the ones who are harmed. Indeed, we can, and do, spay/neuter cats while acknowledging that they have value in their own right. (shrink)

In The Case for Animal Rights, Tom Regan argues that although all subjects-of-a-life have equal inherent value, there are often differences in the value of lives. According to Regan, lives that have the highest value are lives which have more possible sources of satisfaction. Regan claims that the highest source of satisfaction, which is available to only rational beings, is the satisfaction associated with thinking impartially about moral choices. Since rational beings can bring impartial reasons to bear on decision making, (...) Regan maintains that they have an additional possible source of satisfaction that nonrational beings do not have and, consequently, the lives of rational beings turn out to have greater value..

Higher-order thought theories maintain that consciousness involves the having of higher-order thoughts about mental states. In response to these theories of consciousness, an attempt is often made to illustrate that nonhuman animals possess said consciousness, overlooking an alarming consequence: attributing higher-order thought to nonhuman animals might entail that they should be held morally accountable for their actions. I argue that moral responsibility requires more than higher-order thought: moral agency requires a specific higher-order thought which concerns a belief about the rightness (...) or wrongness of affecting another’s mental states. This “moral thought” about the rightness or wrongness is not yet demonstrated in even the most intelligent nonhuman animals, thus we should suspend our judgments about the “rightness” or “wrongness” of their actions while further questioning the recent insistence on developing an animal morality.

It is common for conservationists to refer to non-native species that have undesirable impacts on humans as “invasive”. We argue that the classification of any species as “invasive” constitutes wrongful discrimination. Moreover, we argue that its being wrong to categorize a species as invasive is perfectly compatible with it being morally permissible to kill animals—assuming that conservationists “kill equally”. It simply is not compatible with the double standard that conservationists tend to employ in their decisions about who lives and who (...) dies. (shrink)

The philosophy of animal rights is often characterized as an exclusively justice oriented approach to animal liberation that is unconcerned with, and moreover suspicious of, moral emotions, like sympathy, empathy, and compassion. I argue that the philosophy of animal rights can, and should, acknowledge that compassion plays an integral role in animal liberation discourse and theory. Because compassion motivates moral actors to relieve the serious injustices that other animals face, or, at the very least, compassion moves actors not to participate (...) in or cause these injustices, the philosophy of animal rights can and should recognize both a duty to cultivate compassion and a duty to promote compassion. Contra to feminist critiques of Regan’s justice-approach to ethics, the philosophy of animal rights is not committed to eschewing the moral emotions. (shrink)

An adequate theory of rights ought to forbid the harming of animals to promote trivial interests of humans, as is often done in the animal-user industries. But what should the rights view say about situations in which harming some animals is necessary to prevent intolerable injustices to other animals? I develop an account of respectful treatment on which, under certain conditions, it’s justified to intentionally harm some individuals to prevent serious harm to others. This can be compatible with recognizing the (...) inherent value of the ones who are harmed. My theory has important implications for contemporary moral issues in nonhuman animal ethics, such as the development of cultured meat and animal research. (shrink)

Анотація. У статті проаналізовані досягнення Соціального Вчительства Католицької Церкви, репрезентовані працями Лева ХІІІ, Пія ХІ, Пія ХІІ, Івана Павла ІІ, що розкривають змістовні характеристики поняття «принцип субсидіарності», його роль і значення в системі християнських цінностей. Принцип субсидіарності робить можливими такі взаємовідносини в соціальному житті, коли спільнота вищого порядку не втручається у внутрішнє життя спільноти нижчого порядку, перебираючи на себе належні тій функції; заради спільного добра, спільного блага вона надає їй у разі потреби підтримку й допомогу, узгоджуючи у такий спосіб її (...) взаємодію з іншими соціальними структурами. Принцип субсидіарності скеровує соціальну практику на утвердження спільного блага в людському співтоваристві. Поширення і застосування принципу субсидіарності протистоїть небезпеці «одержавлення» суспільства та найзагрозливіших проявів колективізму, обмежує абсолютизацію влади, бюрократизацію державних і соціокультурних структур, стає одним із гарантів дотримання прав і свобод громадян своєї країни.

Many advocate practices of ‘local food’ or ‘locavorism’ as a partial solution to the injustices and unsustainability of contemporary food systems. I think that there is much to be said in favor of local food movements, but these virtues are insufficient to immunize locavorism from criticism. In particular, three duties of international ethics—beneficence, repair and fairness—may provide reasons for constraining the developed world’s permissible pursuit of local food. A complete account of why (and how) the fulfillment of these duties constrains (...) locavorism will require extensive empirical evidence about the relationship between agricultural demand-led industrialization, international trade (rules), and local food practices. In this paper I can only gesture at some of this evidence and, for that reason, my policy prescriptions are merely provisional. Instead, the upshot of this paper is that advocates of locavorism ought to be attentive to the empirical-dependence of the moral permissibility of their projects. As local food ‘scales up’—and comes to be embraced as a goal of political communities—these concerns should receive even greater attention. (shrink)

Subliminal primes are assumed to produce weaker and short-lived effects on subsequent behavior compared to clearly visible primes. However, this difference in priming effect may be due to differences in signal strength, rather than level of awareness. In the present study we manipulated prime discriminability by using metacontrast masks and pseudomasks, while keeping the prime strength equal. This manipulation resulted in large differences in discriminability of the primes. However, both immediate response priming and long-term response priming was equal for the (...) poorly discriminable and well discriminable primes, and equal for groups that differed markedly in terms of how well they could discriminate the primes. Our findings imply that discriminability of information is independent of both the immediate and long-term effects that information can have on behavior. (shrink)

Because factory-farmed meat production inflicts gratuitous suffering upon animals and wreaks havoc on the environment, there are morally compelling reasons to become vegetarian. Yet industrial plant agriculture causes the death of many field animals, and this leads some to question whether consumers ought to get some of their protein from certain kinds of non factory-farmed meat. Donald Bruckner, for instance, boldly argues that the harm principle implies an obligation to collect and consume roadkill and that strict vegetarianism is thus immoral. (...) But this argument works only if the following claims are true: all humans have access to roadkill, roadkill would go to waste if those who happen upon it don’t themselves consume it, it’s impossible to harvest vegetables without killing animals, the animals who are killed in plant production are all-things-considered harmed by crop farming, and the best arguments for vegetarianism all endorse the harm principle. As I will argue in this paper, each claim is deeply problematic. Consequently, in most cases, humans ought to strictly eat plants and save the roadkill for cats. (shrink)

Limited research has been done among pregnant people participating in investigational drug trials. To enhance the ethical understanding of pregnant people’s perspectives on research participation, we sought to describe motives and risk perceptions of participants in a phase 1 trial of ledipasvir/sofosbuvir treatment for chronic Hepatitis C virus during pregnancy. Pregnant people with chronic HCV infection enrolled in an open-label, phase 1 study of LDV/SOF participated in semi-structured, in-depth interviews to explore their reasons for participation and experiences within the study. (...) Pregnant people took 12 weeks of LDV/SOF and were interviewed at enrollment and at the end of study. We recorded the interviews, transcribed them verbatim, coded them using NVivo software, and performed inductive thematic analysis. Nine women completed the study yielding 18 interview transcripts. We identified two themes regarding motives and one regarding risk perception. Motives— Women conceptualized study participation as part of the caregiving role they associate with motherhood; participating was viewed as an act of caregiving for their infants, their families, themselves, and other pregnant women with chronic HCV. Women also noted that they faced multiple barriers to treatment prior to pregnancy that created a desire to receive therapy through trial participation. Risk perception— Women acknowledged personal and fetal risk associated with participation. Acceptance of risk was influenced by women’s concepts of motherhood, preexisting knowledge of HCV and medical research, family members, intimate partners, or by the study design. Women enrolled in a phase 1 trial for chronic HCV therapy during pregnancy acknowledged risks of participation and were motivated by hopes for fetal and personal benefit and by lack of prenatal access to treatment. Ethical inclusion of pregnant people in research should acknowledge structural factors that contribute to vulnerability and data deficiencies for treatment in pregnancy. (shrink)

For some time now a number of critics have argued that Juergen Habermas has misinterpreted Freud. The gist of this criticism is that Habermas' interpretation of psychoanalysis as `depth hermeneutics' must violate the intent of Freud's work, which is so deeply grounded in drive theory. In other words, Habermas confuses philosophical reflection with psychoanalysis. This paper takes a somewhat different focus. It examines the consequences of Habermas' interpretation of Freud for Habermas' view of the individual. It is shown that Habermas' (...) interpretation eventuates in an abstract and shadowy view of the individual. It is argued that an alternative view of psychoanalysis, object relations theory, can help locate the source of Habermas' pale view of the individual, and help correct it, without succumbing to `neo-Freudian revisionism'. Object relations theory also suggests that in order to overcome the diminution of the individual in real life it is necessary for political theory to examine seriously the role of the family. Finally, object relations theory generates an interesting criticism of so-called postmodern psychoanalysis—for example, the work of Jacques Lacan. This criticism can help us better understand the relationship between Habermas and modernism. (shrink)
