The October 2016 publication of the 2015 convegno on Peter of John Olivi begins with a fine survey of Provence and Languedoc in Olivi's time. J. Chiffoleau, with C. Lenoble, supplies the reader with much detail and some summary, along with abundant reference, on Olivi's home turf. In the come and go of life religious and lay, Olivi saw to critical support for business while trying to stabilize Franciscan life. He did very well by both. Chiffoleau finishes his pages on (...) Olivi's days by suggesting that Olivi had better to do around Narbonne than in Paris.Tiziana Suarez-Nani offers thoughts and examples of Peter Olivi's "spiritual philosophy". That he offers Aristotle little esteem we know; that Olivi... (shrink)

There is general acknowledgement that both the anterior cingulate and orbitofrontal cortex are implicated in reinforcement-guided decision making, and emotion and social behaviour. Despite the interest that these areas generate in both the cognitive neuroscience laboratory and the psychiatric clinic, ideas about the distinctive contributions made by each have only recently begun to emerge. This reflects an increasing understanding of the component processes that underlie reinforcement- guided decision making, such as the representation of reinforcement expectations, the exploration, updating and representation (...) of action values, and the appreciation that choices are guided not just by the prospect of reward but also by the costs that action entails. Evidence is emerging to suggest that the anterior cingulate and orbitofrontal cortex make distinct contributions to each of these aspects of decision making. (shrink)

We consider the desirability, or otherwise, of various forms of induction in the light of certain principles and inductive methods within predicate uncertain reasoning. Our general conclusion is that there remain conflicts within the area whose resolution will require a deeper understanding of the fundamental relationship between individuals and properties.

In this paper we first give a survey of reductive cut-elimination methods in classical logic. In particular we describe the methods of Gentzen and Schütte-Tait from the abstract point of view of proof reduction. We also present the method CERES which we classify as a semi-semantic method. In a further section we describe the so-called semantic methods. In the second part of the paper we carry the proof analysis further by generalizing the CERES method to CERESD . In the generalized (...) version CERESD we admit general elimination rules which are based on the mere semantical truth of sentences. We construct complete cut-free LK-derivations originating from derivations potentially containing unproven lemmas. Finally we give a comparison of reductive methods and CERESD by presenting a general simulation result. (shrink)

The ethical and legal challenges posed by assisted reproduction techniques are both profound and breathtaking, with most societies unable to fully comprehend one technique before another one, even more daring, emerges. The wrongful implantation of embryos in two women undergoing in vitro fertilisation treatments at two separate clinics in the UK seriously vitiates the traditional concept of who is a parent. In one case, a patient’s embryos were wrongly implanted into another woman seeking similar treatment, and in the second, a (...) woman’s eggs were fertilised using sperm from a man other than her husband.In the first mix-up, neither member of the recipient couple was the genetic parent of the child, while in the second case, the recipient mother was the genetic mother and her husband was not the genetic father. The mix-ups resulted in litigation to determine who the rightful parents were. First, I will show in this paper that, although the outcome of the application of English law in both cases was in agreement with the outcome prescribed by basic principles of Islamic law and bioethics, that agreement is based on different reasoning in the two traditions. Next, I will show that the profound ethical implications of reproductive technologies begs for a more pluralistic bioethical discourse than the one-dimensional analysis applied by secular Western societies that currently dominates the enquiry, particularly as most Western societies are more or less multicultural and multireligious.

Charting the development of the British tradition of naturalism from the 17th to the 19th century, this book provides fascinating insight into a wide range of thinkers, both Catholic and Protestant, who explored the themes of proof, practice, and the role of common sense. Reappraising what these thinkers can teach us about the relations between belief, action, and skepticism, Ferreira contributes to the philosophical study of naturalist replies to skepticism, as well as to a deeper appreciation of this particular segment (...) of British intellectual history.

Since 1994, when the first fetal imaging boutique appeared in Texas, many sites have been established around the country for parents to receive nonmedical fetal imaging using three- and four-dimensional ultrasound machines. These businesses boast the benefits they offer to parental-fetal bonding, but the medical community objects to the use of ultrasound machines for nonmedical purposes. In this article, I present the statements released by the medical community, highlighting the alarmist strategies used to paint boutique ultrasounds as bad science and (...) elevate the medical use of ultrasounds. Through a close reading of the statements, it is shown that the medical community's primary concern is not the health of the fetus or the woman but rather their place as the sole users of fetal ultrasounds. This detailed analysis reveals a medical community fearful that its authority is being usurped and is therefore responding with statements meant to denigrate boutique fetal ultrasounds. (shrink)

Poor pregnancy outcomes and inequalities in these outcomes remain a major challenge, even in prosperous societies that have high-quality health care and public health policy in place. In this article, we propose that justice demands the improvement of what we call the ‘health agency’ of parents-to-be as part of a response to these poor outcomes. We take health agency to have three aspects: the capacity to form health-goals one has reason to value, the control one perceives to have over achieving (...) those health-goals and the freedom one has to achieve those health-goals. We will moreover argue that this demand of justice can be best based on a perfectionist rather than neutralist method of justification. Subsequently, we will argue that perfectionist policy may be paternalistic but not wrongfully paternalistic. This leads us to conclude that perfectionism should be adopted to inform and justify public health policy that is aimed at improving health agency in general and counteracting poor pregnancy outcomes and inequalities in perinatal health outcomes in particular.

Philosophical Thought in Russia in the Second Half of the 20th Century is the first book of its kind that offers a systematic overview of an often misrepresented period in Russia's philosophy. Focusing on philosophical ideas produced during the late 1950s – early 1990s, it reconstructs the development of genuine philosophical thought in the Soviet period and introduces those non-dogmatic Russian thinkers who saw in philosophy a means of reforming social and intellectual life. Covering such areas of philosophical inquiry as (...) philosophy of science, philosophical anthropology, the history of philosophy, activity approach as well as communication and dialogue studies, the volume presents and thoroughly discusses central topics and concepts developed by Soviet thinkers in that particular fields. Written by a team of internationally recognized scholars from Russia and abroad, it examines the work of well-known Soviet philosophers (such as Mikhail Bakhtin, Evald Ilyenkov and Merab Mamardashvili) as well as those important figures (such as Vladimir Bibler, Alexander Zinoviev, Yury Lotman, Georgy Shchedrovitsky, Genrich Batishchev, Sergey Rubinstein, and others) who have often been overlooked. By introducing and examining original philosophical ideas that evolved in the Soviet period, the book confirms that not all Soviet philosophy was dogmatic and tied to orthodox Marxism and the ideology of Marxism-Leninism. It shows Russian philosophical development of the Soviet period in a new light, as a philosophy defined by a genuine discourse of exploration and intellectual progress, rather than stagnation and dogmatism. In addition to providing the historical and cultural background that explains the development of the 20th-century Russian philosophy, the book also puts the discussed ideas and theories in the context of contemporary philosophical discussions showing their relevance to nowadays debates in Western philosophy. With short biographies of key thinkers, an extensive current bibliography and a detailed chronology of Soviet philosophy, this research resource provides a new understanding of the Soviet period and its intellectual legacy 100 years after the Russian Revolution.

In this paper we will show that Hempel's covering law model can't deal very well with explanations that are based on incomplete knowledge. In particular the symmetry thesis, which is an important aspect of the covering law model, turns out to be problematic for these explanations. We will discuss an example of an electric circuit, which clearly indicates that the symmetry of explanation and prediction does not always hold. It will be argued that an alternative logic for causal explanation is (...) needed. And we will investigate to what extent non-monotonic epistemic logic can provide such an alternative logical framework. Finally we will show that our non-monotonic logical analysis of explanation is not only suitable for simple cases such as the electric circuit, but that it also sheds new light on more controversial causal explanations such as Milton Friedman's explanation of the business cycle.
