In a previous work [the second and the third author, “On paraconsistent deontic logic”, Philosophia 16, 293-303 (1986)] investigated certain systems of paraconsistent deontic in order to investigate the problem of contradiction in the domain of ethics. This paper continues this line of research, studying some paraconsistent systems containing alethic and deontic modalities. This approach allows us to treat the principles of Kant (OA→ \diamond A) and Hintikka (\square A → OA) from the classical and from the paraconsistent point of (...) view, and to propose systems in which either, both, or neither of these principles is valid.

RESUMO O objetivo desse artigo é fundamentar uma avaliação sobre o final do século V a.C. em Atenas pelas lentes de uma comédia aristofânica. Atenta-se para a atuação das facções políticas (ou hetaireías), que não se restringiam apenas ao espaço das assembleias públicas, mas consolidavam, pelo financiamento das obras dramáticas, uma forma de atingir o público politicamente de maneira persuasiva: os cidadãos que poderiam votar nas ideias debatidas dentro das assembleias. Para tanto, propõem-se uma reflexão acerca do sistema da choregía (...) como forma de dominação, uma análise acerca das orações de Andócides de 415 a.C. sobre as disputas pelo espaço político - seja atuando no teatro, seja de forma oculta, pela ação de grupos de sublevação de poder - e, por fim, uma investigação do tema no exame discursivo da comédia As rãs de Aristófanes (Bátrachoi - 405 a.C.).

This paper builds on some important recent work by Amie Thomasson, wherein she argues that recent disputes about the existence of ordinary objects have arisen due to eliminiativist metaphysicians’ misunderstandings. Some, she argues, are mistaken about how the language of quantification works, while others neglect the existence and significance of certain analytic entailments. Thomasson claims that once these misunderstandings are cleared away, it is trivially easy to answer existence questions about ordinary objects using everyday empirical methods of investigation. She reveals (...) how two conflicting metaontologies can lead to different positions in the first-order debate. In this paper, I bring a third metaontological perspective to the table: one that enables us to maintain that ontological disputes about ordinary objects are not trivially easy to settle, even if we agree with Thomasson that they are merely verbal. These are serious verbal disputes. (shrink)

Sense-perception is a hackneyed topic, and I must therefore begin by craving your indulgence. I was moved to make it the subject of this evening's lecture by the fact that I have lately been reading the book in which the most important of the late Professor Prichard's scattered writings on Sense-perception have been collected by Sir W. D. Ross. Like everything that Prichard wrote, these essays are extremely acute, transparently honest, and admirably thorough. I shall not attempt here either to (...) expound or to criticize Prichard, but he may be taken to be hovering, perhaps somewhat disapprovingly, in the background during the lecture. (shrink)

Most whistleblowers talk as if they never had a choice about whether to blow the whistle. This doesn't mean they acted suddenly, or impulsively, only that they believe they could not have done otherwise. Trying to make sense of this near universal answer to the question "Why did you do it?" the essay draws on narrative theory. Narrative theory distinguishes between actant and sender—that is, between actor and his or her values. This distinction helps to explain what it means to (...) face a difficult choice over something about which one feels one never had a choice. (shrink)

What ecological advantages do animals gain by being able to detect, extract and exploit wavelength information? What are the advantages of representing that information as hue qualities? The benefits of adding chromatic to achromatic vision, marginal in object detection, become apparent in object recognition and receiving biological signals. It is argued that this improved performance is a direct consequence of the fact that many animals' visual systems reduce wavelength information to combinations of four basic hues. This engenders a simple categorical (...) scheme that permits a rich amount of sensory information to be rapidly and efficiently employed by cognitive machinery of limited capacity. (shrink)

The Holocaust marks a decisive moment in modern suffering in which it becomes almost impossible to find meaning or redemption in the experience. In this study, C. Fred Alford offers a new and thoughtful examination of the experience of suffering. Moving from the Book of Job, an account of meaningful suffering in a God-drenched world, to the work of Primo Levi, who attempted to find meaning in the Holocaust through absolute clarity of insight, he concludes that neither strategy works well (...) in today's world. More effective are the day-to-day coping practices of some survivors. Drawing on testimonies of survivors from the Fortunoff Video Archives, Alford also applies the work of Julia Kristeva and the psychoanalyst Donald Winnicot to his examination of a topic that has been and continues to be central to human experience.

Recently, Brukner and Zeilinger 3354) have claimed that the Shannon information is not well defined as a measure of information in quantum mechanics, adducing arguments that seek to show that it is inextricably tied to classical notions of measurement. It is shown here that these arguments do not succeed: the Shannon information does not have problematic ties to classical concepts. In a further argument, Brukner and Zeilinger compare the Shannon information unfavourably to their preferred information measure, I , with regard (...) to the definition of a notion of “total information content.” This argument is found unconvincing and the relationship between individual measures of information and notions of “total information content” investigated. We close by considering the prospects of Zeilinger's Foundational Principle as a foundational principle for quantum mechanics. (shrink)

Rising global demand for meat will result in increased environmental pollution, energy consumption, and animal suffering. Cultured meat, produced in an animal-cell cultivation process, is a technically feasible alternative lacking these disadvantages, provided that an animal-component-free growth medium can be developed. Small-scale production looks particularly promising, not only technologically but also for societal acceptance. Economic feasibility, however, emerges as the real obstacle.

The development of gene-editing technologies, such as the clustered regularly interspaced short palindromic repeats and associated Cas9 endonuclease system, coincides with a rapidly expanding knowledge of the role of genes in the human ageing process. This raises the prospect that, in addition to the treatment of genetic diseases and disorders, it may become possible to use gene-editing technologies to alter the ageing process and significantly extend the maximum human lifespan. Germline editing poses distinctive problems due to its implications for individual (...) members of future, unborn generations. In this essay, I wish to home in, narrowly, on a single ethical objection to extending the lifespan of future generations by editing the human germline. The objection suggests that to extend lifespans is to unethically inflict the harm of loneliness on future people. I claim that the argument rests on assumptions that ought to be rejected. (shrink)

In an era dominated by information and communication technologies, when science continues to amaze us with its discoveries and technological applications, and when social media are controlling part of our lives and social relationships, does philosophy still make sense? Is humanistic knowledge still necessary today as an indispensable part of our human world?

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)

Stephen Yates's objections to Feyerabend's political theory (Inquiry 27 [1984], 137?42) are presented in a way that makes them unnecessarily vulnerable to a rhetorical strategy often employed by Feyerabend. Like many other critics, Yates seems to assume that it is the implausibility of Feyerabend's claims that opens them to refutation, whereas it is really this that makes them such slippery targets of criticism. Rather than claim that Feyerabend's ideal would be virtually impossible to realize, I argue that Feyerabend does not (...) demonstrate why ?democratic relativism? is at all desirable. (shrink)

Antievolution arguments of Christian and Hindu creationists often critique Darwin's metaphor of the geological record as an ill‐preserved book of life, while highlighting the problem of anomalous fossils. For instance, Bible‐based young‐Earth creationists point to anomalous humanlike prints alongside authenticated dinosaur tracks to argue for the creation of all life some few thousand years ago. But Vedic‐based ancient‐hominid creationists view the same sort of evidence as indicating the existence of all species, including the hominids, billions of years ago. I examine (...) the roots of this Hindu Vedic creationism and its recent elaboration among scientifically minded members of the International Society for Krishna Consciousness (ISKCON). Similarities in the methods and rhetorical strategies of the two creationist groups are considered, as well as the underlying motives that have brought together such otherwise disparate religious worldviews.

David Hume has been invoked by those who want to found morality on human nature as well as by their critics. He is credited with showing us the fallacy of moving from premises about what is the case to conclusions about what ought to be the case; and yet, just a few pages after the famous is-ought remarks in A Treatise of Human Nature, he embarks on his equally famous derivation of the obligations of justice from facts about the cooperative (...) schemes accepted in human communities. Is he ambivalent on the relationship between facts about human nature and human evaluations? Does he contradict himself – and, if so, which part of his whole position is most valuable? Between the famous is-ought passage and the famous account of convention and the obligations arising from established cooperative schemes once they are morally endorsed, Hume discusses the various meanings of the term “natural.” “Shou'd it be ask'd, Whether we ought to search for these principles [upon which all our notions of morals are founded] in nature or whether we must look for them in some other origin? I wou'd reply, that our answer to this question depends upon the definition of the word, Nature, than which there is none more ambiguous and equivocal.” The natural can be opposed to the miraculous, the unusual, or the artificial. It is the last contrast that Hume wants, for his contrast between the “artificial” culturally variant, convention-dependent obligations of justice and the more invariant “natural virtues,” and what he says about that contrast in this preparation for his account of the “artificial” virtues, makes it clear why he can later refer to justice as “natural” and to the general content of the rules of justice – that is, of basic human conventions of cooperation – as “Laws of Nature”.

A simple geometry utilizing a laser-excited atomic beam as light source, and a nearby oscillating mirror, would permit the observation of a two-channel optical interference effect involving photons which can be localized predominantly in one channel by coincidence observations of the recoiling source atom. A sacrifice of the optimum conditions for photon interference is necessary even when photon localization in one channel is accomplished by an observation of the recoil atom. This necessity arises because the width of the slit defining (...) the atomic beam, and with it the important optical source dimension, must be comparable to the optical wavelength to obtain the small uncertainty in initial total momentum needed for significant localization. Quantum mechanical calculations of the coincidence intensity and singles intensity as a function of mirror position are made for a source width of five quarter wavelengths and are compared to a classical optics calculation of the singles intensity. The coincidence intensity calculation, as expected, predicts a smaller interference effect than classical optics due to the photon localization. The singles intensity calculation also predicts the same reduction in the classical interference effect, as a consequence of the orthoganality of the final atom states. (shrink)

The introduction of mass public education posed unfamiliar problems for the governments of modern states, and the ways in which governments worked through those problems can reveal much about the culture and values of a state. This paper focuses on central Government officials and the Ministers they advised, with particular attention to the pivotal period 1960-1976. Trends identified include: the shift from post-War optimism to the more pessimistic view of schooling since the late 1960s; the dynamics of professional development amid (...) over-rapid expansion and contraction; relationships between training institutions and schools; and policy-makers' changing perceptions of teachers as professionals. Four themes are considered in detail: the imperatives of numbers; status concerns as a driver of change; linkages among the 'partners' in the schooling enterprise; and accountability. Some questions are posed about the sustainability of the schooling enterprise in England and Wales. (shrink)
