A major difficulty for currently existing theories of inductive inference involves the question of what to do when novel, unknown, or previously unsuspected phenomena occur. In this paper one particular instance of this difficulty is considered, the so-called sampling of species problem.The classical probabilistic theories of inductive inference due to Laplace, Johnson, de Finetti, and Carnap adopt a model of simple enumerative induction in which there are a prespecified number of types or species which may be observed. But, realistically, this (...) is often not the case. In 1838 the English mathematician Augustus De Morgan proposed a modification of the Laplacian model to accommodate situations where the possible types or species to be observed are not assumed to be known in advance; but he did not advance a justification for his solution.

The purpose of this paper is to make a simple observation regarding the Johnson -Carnap continuum of inductive methods. From the outset, a common criticism of this continuum was its failure to permit the confirmation of universal generalizations: that is, if an event has unfailingly occurred in the past, the failure of the continuum to give some weight to the possibility that the event will continue to occur without fail in the future. The Johnson -Carnap continuum is the mathematical consequence (...) of an axiom termed Johnson 's sufficientness postulate, the thesis of this paper is that, properly viewed, the failure of the Johnson -Carnap continuum to confirm universal generalizations is not a deep fact, but rather an immediate consequence of the sufficientness postulate; and that if this postulate is modified in the minimal manner necessary to eliminate such an entailment, then the result is a new continuum that differs from the old one in precisely one respect: it enjoys the desideratum of confirming universal generalizations.

Brian Skyrms (1987, 1990, 1993, 1997) has discussed the role of dynamic coherence arguments in the theory of personal or subjective probability. In particular, Skryms (1997) both reviews and discusses the utility of martingale arguments in establishing the convergence of beliefs within the context of radical probabilism. The classical martingale converence theorem, however, assumes the countable additivity of the underlying probability measure; an assumption rejected by some subjectivists such as Bruno de Finetti (see, e.g., de Finetti 1930 and 1972). This (...) brief note has a very modest goal: to briefly consider the extent to which Skyrms’s argument can be extended to the finitely additive case. (shrink)

This paper has the aim of making Johannes von Kries’s masterpiece, Die Principien der Wahrscheinlichkeitsrechnung of 1886, a little more accessible to the modern reader in three modest ways: first, it discusses the historical background to the book ; next, it summarizes the basic elements of von Kries’s approach ; and finally, it examines the so-called “principle of cogent reason” with which von Kries’s name is often identified in the English literature.

The Unknowable, arguably the greatest Russian philosophical work of the 20th century, was the culmination of S. L. Frank's intellectual and spiritual development, the boldest and most imaginative of all his writings, containing a synthesis of epistemology, ontology, social philosophy, religious philosophy, and personal spiritual experience.

According to Heidegger, we are living in an ever worsening ?worldnight?, whose fundamental nihilism is due to an ?abandonment by Being? (Seinsverlassenheit) or a ?forgetting of Being? (Seinsvergessenheit). In this paper, I attempt to clarify the notion of an ?abandonment by Being? through an examination of two themes prominent in Heidegger's later philosophy: Being as ?event? (Ereignis); and the obscure ?mystery? or ?secret? of Being. ?Seinsvergessenheit? is interpreted as a forgetting of the mystery or secret of Being which is the (...) ?ontological difference? between Being and beings, i.e. between some concrete revelation of a world and the conditions which make possible any revelation whatsoever. Since these conditions make up that ontological structure which is Dasein and since Dasein is human being, to forget Being is to be in a condition of profound self?estrangement. The origin and growth of this condition constitutes the history of metaphysics, which unfolds as the history of a progressive increase in ?subjectivism?, culminating in the nihilistic ?will to will? as the mode of revelation of the modern world. Finally, Heidegger's two ?remedies? for Seinsverlassenheit are examined: the first, the need for a cultivation of ?essential thinking? is shown to be fundamentally sterile and unable, therefore, to bear the burden of world?transformation which Heidegger lays upon it, while the second, the exhortation to experience the ?thing? as ?assembler? of the ?foursome?, it is argued, does not grow organically out of Heidegger's central philosophical preoccupations, but represents quite a radical departure from them.

“Doing Gender,” Candance West and Don Zimmerman’s famous 1987 article, has become a folk concept—a trope or commonsense resource within the sociology of gender. Yet at the same time, most gender scholars overlook its ethnomethodological premise, visible in both poststructuralist misunderstandings of its argument outside the discipline of sociology and what I term a realist misunderstanding of it in the study of structures and identities within the discipline. Reading West and Zimmerman queerly while clarifying ethnomethodology’s ontology, I refocus attention for (...) critical scholarship on ethnomethodology’s analytic sensibilities for research on gender, race, and sexuality, among other embodiments. Specifically, ethnomethodology reframes a vision of actors as relational, practical actors; repositions gender as accountable, jointly produced social relations, not individual identity; and foregrounds resistance in addition to conformity. Hence, my gender is not mine; it is ours. Ethnomethodology’s ontological shift in temporality to reality-in-production enables interpretive-materialism: a queer, anti-racist, intersectional sociology that is future-facing and in motion.

This article explores refusal of medical treatment by adult patients from ethical and legal perspectives. Initially, consequentialist and deontological ethical theory are outlined. The concepts of autonomy, paternalism and competence are described and an overview of Beauchamp and Childress’s principle-based approach to moral reasoning is given. Relevant common law is discussed and the provisions of the Mental Capacity Act 2005 in assessing competence is evaluated. In order to demonstrate the consideration of moral issues in clinical practice, ethical theory is applied (...) to two well-known incidents: the case of Re MB, where doubt over decision-making capacity led to a paternalistic act to override a patient’s choice; and the death of Emma Gough, a situation where respect for autonomy prevailed when healthcare staff acted lawfully in following a patient’s refusal of life-saving treatment. Finally, guidance from regulatory bodies on the roles and responsibilities of health professionals in relation to this topic are considered. (shrink)

Inducing the rubber hand illusion (RHI) requires that participants look at an imitation hand while it is stroked in synchrony with their occluded biological hand. Previous explanations of the RHI have emphasized multisensory integration, and excluded higher cognitive functions. We investigated the relationship between the RHI and higher cognitive functions by experimentally testing task switch (as measured by switch cost) and mind wandering (as measured by SART score); we also included a questionnaire for attentional control that comprises two subscales, attention-shift (...) and attention-focus. To assess experience of RHI, the Botvinick and Cohen (1998) questionnaire was used and illusion onset time was recorded. Our results indicate that rapidity of onset reliably indicates illusion strength. Regression analysis revealed that participants evincing less switch cost and higher attention-shift scores had faster RHI onset times, and that those with higher attention-shift scores experienced the RHI more vividly. These results suggest that the multi-sensory hypothesis is not sufficient to explain the illusion: higher cognitive functions should be taken into account when explaining variation in the experience of ownership for the rubber hand.

Gaining ethical clearance to conduct a study is an important aspect of all research involving humans but can be time-consuming and daunting for novice researchers. This article stems from a larger ethnographic study that examined research capacity building in Irish nursing and midwifery. Data were collected over a 28-month time frame from a purposive sample of 16 nurse or midwife research fellows who were funded to undertake full-time PhDs. Gaining ethical clearance for their studies was reported as an early ‘rite (...) of passage’ in the category of ‘labouring the doctorate’. This article penetrates the complexities in Irish clinical research ethics by describing the practices these nurse and midwife researchers encountered and the experiences they had. The key issue of representation that occurred in the context of ‘medicalized’ research ethics is further explored including its meaning for nursing or midwifery research. (shrink)
