The functioning of a subject in a changing environment is most effective from the point of view of survival if the subject can form, maintain and use internal representations of the external world for decision-making. These representations are also called reflection in a broad sense. Using it, one can win in reflexive games since an internal representation of the enemy allows predicting their future moves. The goal is to assess the reflexive potential of heuristic model objects – artificial neural networks (...) – in the reflexive games “Even-Odd” (or “Matching pennies”) and “Rock-Paper-Scissors”. We used homogeneous fully connected neural networks of small sizes (from 8 to 45 neurons). Games were played between neural networks with different configurations and parameters (size, step size for modifying weight coefficients). A set of reflexivity criteria is presented, corresponding to different levels of consideration: neuronal, behavioral, formal. The transitivity of formal success in the game is shown. The most successful configurations, however, may not meet other criteria of reflexivity. We hypothesize that the best compliance with the criteria and, as a consequence, universal success in reflection tasks is achievable for heterogeneous configurations with a structure in which the formation of hierarchical systems of attractors is possible.

This 1990 collection explores one recurrent theme connecting philosophy and politics: the relation between the nature of man and the structure of society. It does so by concentrating on the topical issue of the market economy as an attempt to resolve the clash between individual autonomy and collective action. Beginning with a historical and personal recollection by Enoch Powell and a response by Robert Skidelsky, the volume then provides a forum for political theorists and philosophers to take issue on the (...) fundamental topics of markets and morals; liberal man; and equality and libertarianism. It succeeds equally as a stimulating textbook and a book for the general reader who wishes to understand the philosophical issues arising in a market economy. (shrink)

O texto busca refletir criticamente sobre alguns fenômenos sociais contemporâneos, fortemente imbricados, notadamente as tendências contemporâneas de entrincheiramento e achatamento do eu; o reforço da iconomania e da compulsiva produção de avatares de si, em meio a bolhas narcísicas digitais, franqueadas pelas recentes tecnologias de informação e comunicação; e a virtual destruição da intimidade e da privacidade, diante da emergência de panópticos digitais e da vigilância algorítmica. Para tanto, toma-se como ponto de partida proposições apresentadas por Christopher Lasch em sua (...) obra _The Minimal Self: Psychic Survival in Troubled Times_, publicada originalmente em 1984, em particular a própria noção de mínimo eu, as quais são, então, entretecidas com argumentos de Christophe Dejours, Günther Anders, Theodor Adorno, Hebert Marcuse, Jonathan Crary, entre outros. Em acréscimo, busca-se salientar a ancoragem desses processos à hodierna dinâmica de acumulação de capital, a partir da crítica da economia política, perspectiva que atravessa todo o texto, bem como assinalar a atualidade do pensamento de Lasch.

Critics of Hannah Arendt's Lectures on Kant's Political Philosophy argue that Arendt fails to address the most important problem of political judgment, namely, validity. This essay shows that Arendt does indeed have an answer to the problem that preoccupies her critics, with one important caveat: she does not think that validity is the all-important problem of political judgment--the affirmation of human freedom is.

In this paper we consider an intuitionistic variant of the modal logic S4 (which we call IS4). The novelty of this paper is that we place particular importance on the natural deduction formulation of IS4— our formulation has several important metatheoretic properties. In addition, we study models of IS4— not in the framework of Kirpke semantics, but in the more general framework of category theory. This allows not only a more abstract definition of a whole class of models but also (...) a means of modelling proofs as well as provability. (shrink)

This essay examines the significantly different approaches of John Rawls and Hannah Arendt to the problem of judgment in democratic theory and practice.

Next SectionFollowing the influential Gifford and Reith lectures by Onora O’Neill, this paper explores further the paradigm of individual autonomy which has been so dominant in bioethics until recently and concurs that it is an aberrant application and that conceptions of individual autonomy cannot provide a sufficient and convincing starting point for ethics within medical practice. We suggest that revision of the operational definition of patient autonomy is required for the twenty first century. We follow O’Neill in recommending a principled (...) version of patient autonomy, which for us involves the provision of sufficient and understandable information and space for patients, who have the capacity to make a settled choice about medical interventions on themselves, to do so responsibly in a manner considerate to others. We test it against the patient–doctor relationship in which each fully respects the autonomy of the other based on an unspoken covenant and bilateral trust between the doctor and patient. Indeed we consider that the dominance of the individual autonomy paradigm harmed that relationship. Although it seems to eliminate any residue of medical paternalism we suggest that it has tended to replace it with an equally (or possibly even more) unacceptable bioethical paternalism. In addition it may, for example, lead some doctors to consider mistakenly that unthinking acquiescence to a requested intervention against their clinical judgement is honouring “patient autonomy” when it is, in fact, abrogation of their duty as doctors.

Knowledge of the ethical and legal basis of medicine is as essential to clinical practice as an understanding of basic medical sciences. In the UK, the General Medical Council requires that medical graduates behave according to ethical and legal principles and must know about and comply with the GMC’s ethical guidance and standards. We suggest that these standards can only be achieved when the teaching and learning of medical ethics, law and professionalism are fundamental to, and thoroughly integrated both vertically (...) and horizontally throughout, the curricula of all medical schools as a shared obligation of all teachers. The GMC also requires that each medical school provides adequate teaching time and resources to achieve the above. We reiterate that the adequate provision and coordination of teaching and learning of ethics and law requires at least one full-time senior academic in ethics and law with relevant professional and academic expertise. In this paper we set out an updated indicative core content of learning for medical ethics and law in UK medical schools and describe its origins and the consultative process by which it was achieved.

Aristotle argued that you need some wealth to live well. The Stoics argued that you could live well with or without wealth. But the Cynics argued that wealth is a hinderance. For the Cynics, a good life consists in self-sufficiency, or being able to rule and help yourself. You accomplish this by living simply and naturally, and by subjecting yourself to rigorous philosophical exercises. Cynics confronted people to get them to abandon extraneous possessions and positions of power to live better. (...) And while the Cynics were experts in living in this way, their ascetic lifestyles made their message curious to some audiences. This paper reflects on Cynic ascetic practices and the ways others perceived them. (shrink)

In _Violence and Civility_, Étienne Balibar boldly confronts the insidious causes of violence, racism, nationalism, and ethnic cleansing worldwide, as well as mass poverty and dispossession. Through a novel synthesis of theory and empirical studies of contemporary violence, the acclaimed thinker pushes past the limits of political philosophy to reconceive war, revolution, sovereignty, and class. Through the pathbreaking thought of Derrida, Balibar builds a topography of cruelty converted into extremism by ideology, juxtaposing its subjective forms and its objective manifestations. Engaging (...) with Marx, Hegel, Hobbes, Clausewitz, Schmitt, and Luxemburg, Balibar introduces a new, productive understanding of politics as antiviolence and a fresh approach to achieving and sustaining civility. Rooted in the principles of transformation and empowerment, this theory brings hope to a world increasingly divided even as it draws closer together. (shrink)

The approach used by physics is based on the identification and study of ideal objects, which is also the basis of biophysics, in combination with von Neumann heuristic modeling and functional fractionation according to R.Rosen is discussed as a tool for studying the properties of consciousness. The object of the study is a kind of line of analog systems: the human brain, the vertebrate brain, the invertebrate brain and artificial neural networks capable of reflection, which is a key property characteristic (...) of consciousness. Reflection in the broad sense of the word, understood as an internal representation of the external world, is characteristic of a wide range of animals, and some of them (bumblebees, fish) even demonstrate reflection in the narrow sense of the word, understood as an inner self-representation. This complex behavior is realized by miniature brains of ~1 million neurons. The use of simple recurrent neural networks (RNNs) to obtain answers to general questions is illustrated. For example, it has been shown a small RNS is able to pass delayed matching to sample (DMTS) test, forming an individual dynamic representation of the received stimulus, allowing decoding by a special external neural detector.. It has been demonstrated in the reflexive game “even-odd”, the RNS has a huge advantage over a multi-layered neural network, with the same and a larger number of neurons – reflection defeats regression. It was found that the asymmetry of outcomes in the odd-even game, which was explained by various causes, including psychological ones – “it’s easier to catch up than to run away”, is reproduced in the game of two RNNs. Obviously, there are no psychological causes here and the advantage of the player playing for “even” is explained by the more complex strategy of the “odd” player – he needs to predict the opponent’s move and choose the opposite one.

This paper explores ethical issues relating to the management of patients who are terminally ill and unable to maintain their own nutrition and hydration. A policy of sedation without hydration or nutrition is used in palliative medicine under certain circumstances. The author argues that this policy is dangerous, medically, ethically and legally, and can be disturbing for relatives. The role of the family in management is discussed. This issue requires wide debate by the public and the profession.

Research ethics committees are charged with providing an opinion on whether research proposals are ethical. These committees are overseen by a central office that acts for the Department of Health and hence the State. An advisory group has recently reported back to the Department of Health, recommending that it should deal with inconsistency in the decisions made by different RECs. This article questions the desirability and feasibility of questing for consistent ethical decisions.

A significant proportion of conservationists' work is directed towards efforts to save disappearing species. This relies upon the belief that species extinction is undesirable. When justifications are offered for this belief, they very often rest upon the assumption that extinction brought about by humans is different in kind from other forms of extinction. This paper examines this assumption and reveals that there is indeed good reason to suppose current anthropogenic extinctions to be different in kind from extinctions brought about at (...) other times or by other factors. Having considered – and rejected – quantity and rate of extinction as useful distinguishing factors, four alternative arguments are offered, each identifying a way in which anthropogenic extinction is significantly different from other forms of extinction, even mass extinction: (1) Humans are a different kind of natural cause from other causes of extinction; (2) Extinctions brought about by humans are uniquely persistent; (3) Anthropogenic extinctions are effectively random whereas past mass extinctions are rule-bound; (4) The impact of the current anthropogenic extinction event differs from the impact of other extinction events of the past, such that future recovery may not follow past patterns. Together, these four arguments suggest that the present-day extinction event brought about by humans may be unprecedented and that we cannot clearly extrapolate from past to present recovery from extinctions. Although insufficient as justification for the claim that present-day extinctions are undesirable, the arguments provide some ammunition for conservationists' conviction that species extinction – in which humans play an accelerating role – ought to be prevented.

Traditionally clinicians have determined their patients' resuscitation status without consultation. This has been condemned as morally indefensible in cases where not for resuscitation (NFR) orders are based on quality of life considerations and when the patient's true wishes are not known. Such instances would encompass most resuscitation decisions in elderly patients. Having previously involved patients in CPR decision-making, we chose formally to explore the reasons behind the choices made. Although the patients were not upset, and readily decided at the time (...) of initial consultation, on later analysing the decision-making we found poor understanding of the procedure, poor recall of information given and in some cases evidence of harm. This may be attributed to impaired decision-making capacity of elderly hospitalised patients as previously shown, or to the discomfort precipitated by having to contemplate the apparent immediacy of cardiac arrest by these patients. We propose that subscribing to autonomy as a general principle needs to be balanced against particular cases where distress may be caused by, or result in, diminished competence and limited autonomy.

To speak of ‘the real subject’ or ‘the primary aim’ of a Platonic dialogue usually means to magnify one aspect of it at the expense of other aspects as important. Such is not my intention. It is quite clear, however, without prejudice to the philosophic value of any of the topics discussed, that the Protagoras is an attack upon the sophists as represented by Protagoras, the greatest of them. Hippias and Prodicus are present and some of the great man's glory (...) is reflected upon them; they are also no doubt to some extent implicated in his defeat, though they seem quite unaware of the fact.

There are two fundamentally different approaches to innovation: incremental and radical. In Economics as Anatomy, G.M. Peter Swann argues that economics as a discipline needs both perspectives in order to create the maximum beneficial effect for the economy. Chapters explore how and why mainstream economics is very good at incremental innovation but seems uncomfortable with radical innovation. Swann argues that economics should follow the example of many other disciplines, transitioning from one field to a range of semi-autonomous sub-disciplines. In this (...) book, he compares the missing link in empirical economics to being the economic equivalent of anatomy, the basis of medical discourse. Working as a sequel to Swann's Putting Econometrics in its Place, this book will be a vital resource to those who are discontent with the state of mainstream economics, especially those actively seeking to promote change in the discipline. Students wishing to see progress in the teaching of economics will also benefit from this timely book. (shrink)

Grote's powerful defence of Thrasyllus' canon should have taught us at least not to reject lightly any dialogue which, like the Hippias Maior, is there classed as genuine. The burden of proof lies with those who attack our dialogue. Raeder, Ritter, and Apelt consider it to be genuine, while Ast, Jowett, Horneffer, and Röllig declare against it, as also Gomperz, Zeller, and Lutoslawski.

The author reviews and continues the debate initiated by her recent paper in this journal. The paper was critical of certain aspects of palliative medicine, and caused Ashby and Stoffell to modify the framework they proposed in 1991. It now takes account of the need for artificial hydration to satisfy thirst, or other symptoms due to lack of fluid intake in the terminally ill. There is also a more positive attitude to the emotional needs and ethical views of the patient's (...) family and care-givers. However, clinical concerns about the general reluctance to use artificial hydration in terminal care remain, and doubts persist about the ethical and legal arguments used by some palliative medicine specialists and others, to justify their approach. Published contributions to the debate to date, in professional journals, are reviewed. Key statements relating to the care of sedated terminally ill patients are discussed, and where necessary criticised. (shrink)

The classical Athenian philosopher Socrates was tried in 399 BCE on the basis of two notoriously ambiguous charges: corrupting the youth and impiety (in Greek, asebeia). A majority of the 501 dikasts (Athenian citizen-jurors) voted to convict him. Socrates was ultimately sentenced to death by drinking a hemlock-based liquid. This well-known account of the trial is by Plato, one of Socrates' students and a famous philosopher in his own right. Whether Socrates was punished unjustly is a contested issue which to (...) this day inspires discussions about the nature and meaning of justice. (shrink)

“Free riding,” used as a descriptive term, refers to taking a jointly produced benefit without contributing towards its production. Used as a term of criticism, it refers to the wrongful failure to contribute towards the joint production of benefits that one receives. On either usage, the central interest of moral philosophy in free riding is the same: to specify the conditions under which not contributing towards the joint production of benefits that one receives is wrong, and to explain why.

Zuidema et al. illustrate how empirical AGL studies can benefit from computational models and techniques. Computational models can help clarifying theories, and thus in delineating research questions, but also in facilitating experimental design, stimulus generation, and data analysis. The authors show, with a series of examples, how computational modeling can be integrated with empirical AGL approaches, and how model selection techniques can indicate the most likely model to explain experimental outcomes.

The Organ Donation Act 2019 has introduced an opt-out organ donor register in England, meaning that consent to the donation of organs upon death is presumed unless an objection during life was actively expressed. By assessing the rights of the dead over their organs, the sick to those same organs, and the role of consent in their requisition, this paper interrogates whether such paradigms for deceased organ donation are ethically justifiable. Where legal considerations are applicable, I focus on the recent (...) changes in England as a case in point; however, this paper ultimately challenges the justifiability of opt-out systems in any form, concluding that ethical solutions to organ shortage do not lie in opt-out systems of deceased organ procurement.
