Victor Quinn advocates teaching critical thinking as a curriculum subject. He has accused Professor John E. McPeck, a vehement critic of such proposals, not only of being wrong but also of being in need of such a critical thinking course himself. In this paper we examine the five supposed critical thinking weaknesses of which McPeck is accused and consider what Quinn's arguments tell us about critical thinking, its skills, its priorities and its claims to subject status.

Within the school of thought known as Critical Thinking, identifying or finding missing assumptions is viewed as one of the principal thinking skills. Within the new subject in schools and colleges, usually called Critical Thinking, the skill of finding missing assumptions is similarly prominent, as it is in that subject's public examinations. In this article we examine how school- and college-focused texts explain and teach ‘this very important skill’. The same texts also deal with the nature of assumptions, validity and (...) the role of stated reasons in arguments, and the way these matters are tackled will also be examined in our inquiry. In addition we explore what respected contributors to the critical thinking movement have had to say about some of these issues. (shrink)

Among hunter-gatherers, the sharing of male and female foods is often assumed to result in virtually the same diet for males and females. Although food sharing is widespread among the hunting and gathering Hadza of Tanzania, women were observed eating significantly more tubers than men. This study investigates the relationship between patterns of dental wear, diet, and extramasticatory use of teeth among the Hadza. Casts of the upper dentitions were made from molds taken from 126 adults and scored according to (...) the Murphy dental attrition scoring system. Females had significantly greater anterior occlusal wear than males when we controlled for age. Males exhibited greater asymmetry in wear, with greater wear on the left side in canines, first premolars, and first molars. We suggest that these sex differences in wear patterns reflect the differences seen in the diet, as well as in the use of teeth as tools. (shrink)

As one of the few philosophers to subject civilisation and barbarism to close analysis, Collingwood was acutely aware of the interrelationship between philosophy and history. This book combines historical, biographical and philosophical discussion in order to illuminate Collingwood's thinking and create the first in-depth analysis of Collingwood's responses to the Second World War.

[Open access] In this book symposium the author takes up questions from phenomenology, hermeneutics, ethical theory, and intellectual history raised by a group of scholarly interlocutors from a range of backgrounds. In the course of engaging with these issues, he discusses, inter alia, McDowell’s realism, Jonathon Lear’s work on the end of a world, Michael Oakeshott’s view of selfhood, Heidegger’s conception of Jemeinigkeit, Uexküll’s notion of Umwelt, and Gadamer’s hermeneutic conception of truth.

Conscientious objections (CO) can be disruptive in a variety of ways and may disadvantage patients and colleagues who must step-in to assume care. Nevertheless, nurses have a right and responsibility to object to participation in interventions that would seriously harm their sense of integrity. This is an ethical problem of balancing risks and responsibilities related to patient care. Here we explore the problem and propose a nonlinear framework for exploring the authenticity of a claim of CO from the perspective of (...) the nurse and of those who must evaluate such claims. We synthesized the framework using Rest’s Four Component Model of moral reasoning along with tenets of the International Council of Nursing’s (ICN) Code of Ethics for Nurses and insights from relevant ethics and nursing ethics literature. The resulting framework facilitates evaluating potential consequences of a given CO for all involved. We propose that the framework can also serve as an aid for nurse educators as they prepare students for practice. Gaining clarity about the sense in which the concept of conscience provides a defensible foundation for objecting to legally, or otherwise ethically, permissible actions, in any given case is critical to arriving at an ethical and reasonable plan of action.

Understanding the mechanisms of early embryonic patterning and the timely allocation of specific cells to embryonic regions and fates as well as their development into tissues and organs, is a fundamental problem in Developmental Biology. The classical explanation for this process had been built around the notion of positional information. Accordingly the programmed appearance of sources of Morphogens at localized positions within a field of cells directs their differentiation. Recently, the development of organs and tissues from unpatterned and initially identical (...) stem cells (adult and embryonic) has challenged the need for positional information and even the integrity of the embryo, for pattern formation. Here we review the emerging area of organoid biology from the perspective of Developmental Biology. We argue that the events underlying the development of these systems are not purely linked to “self‐organization,” as often suggested, but rather to a process of genetically encoded self‐assembly where genetic programs encode and control the emergence of biological structures.

The central theme of this book is the relationship between the reflections about and the realization of a musical composition. In his essay "Words about Music, or Analysis versus Performance," Nicholas Cook states that words and music can never be aligned exactly with one another. He embarks on a quest for models of the relationship between analytical conception and performance that are more challenging than those in general currency. Peter Johnson's essay, "Performance and the Listening Experience: Bach's 'Erbarme (...) dich'" shows that a performance is an element within the intentionality of the work itself. He looks for scientific methods capable of proving the artisticity of a performance. And the composer Hans Zender, in his "A Road Map for Orpheus?," states that a composer must be capable of questioning obvious basic principles (such as equal temperament) and finding creative solutions.

The valencies of the lanthanides vary more than was once thought. In addition to valencies associated with a half-full shell, there are valencies associated with a quarter- and three-quarter-full shell. This can be explained on the basis of Slater’s theory of many-electron atoms. The same theory explains the variation in complexing constants in the trivalent state. Valency in metallic and organometallic compounds is also discussed.

Although it is widely acknowledged that Foucault’s accounts of the concept of heterotopia remain briefly sketched and somewhat confusing, the notion has provoked many interpretations and applications across a range of disciplines. In particular, it has been coupled with different stages or processes of modernity and persistently linked to forms of resistance. This article re-examines Foucault’s concept through a close textual analysis. It contrasts heterotopia with Lefebvre’s conceptualization of heterotopy and wider formulations of utopia. Drawing on Foucault’s study of the (...) spaces of literature of Borges, and particularly Blanchot, the article argues that heterotopia refers to varied spatial and temporal disruptions that imaginatively interrogate and undermine certain formulations of utopia. It concludes by outlining how heterotopia contests the space in which we live. (shrink)

ABSTRACTCollingwood's The New Leviathan is a difficult text. It comprises philosophy, political theory, political opinion and history in what is sometimes an uneasy amalgam. Despite its being the culmination of thirty years of work in ethics and political theory, the final text was clearly affected by the adverse circumstances under which it was written, these largely being Collingwood's illness which increasingly affected his ability to work as the writing of The New Leviathan progressed. This paper seeks to disentangle the composition (...) of the book thereby shedding light on its distinctive character as the last substantial piece of philosophical work published in Collingwood's lifetime.

The place of moral innocence in politics is the central theme of Peter Johnson's subtle and original book.

Adults and infants display a robust ability to perceive the unity of a center-occluded object when the visible ends of the object undergo common motion (e.g. Kellman, P.J., Spelke, E.S., 1983. Perception of partly occluded objects in infancy. Cognitive Psychology 15, 483±524). Ecologically oriented accounts of this ability focus on the primacy of motion in the perception of segregated objects, but Gestalt theory suggests a broader possibility: observers may perceive object unity by detecting patterns of synchronous change, of which common (...) motion is a special case. We investigated this possibility with observations of adults and 4-month-old infants. Participants viewed a center-occluded object whose visible surfaces were either misaligned or aligned, stationary or moving, and unchanging or synchronously changing in color or bright- ness in various temporal patterns (e.g. ¯ashing). Both alignment and common motion con- tributed to adults' perception of object unity, but synchronous color changes did not. For infants, motion was an important determinant of object unity, but other synchronous changes and edge alignment were not. When a stationary object with aligned edges underwent syn- chronous changes in color or brightness, infants showed high levels of attention to the object, but their perception of its unity appeared to be indeterminate. An inherent preference for fast over slow ¯ash rates, and a novelty preference elicited by a change in rate, both indicated that infants detected the synchronous changes, although they failed to use them as information for object unity. These ®ndings favor ecologically oriented accounts of object perception in which surface motion plays a privileged role. Ó 1999 Elsevier Science B.V. All rights reserved. (shrink)

The aim of this book is to provide a realist account of the constants in physics as an alternative to the prevailing conventionalist perspective of many philosophers. To do so the author first focuses on the discussion of the most primitive categories of physical constants which underlie modern science. Subsequently, the conventionalist case is examined in depth and, while held to be coherent, is shown to provide an incomplete account of how constants and related concepts of dimensions function in science. (...) Having repudiated the conventionalist challenge, the positive case for a realist account is then considered and is found to be comfortably accommodated by modest realist accounts such as the natural ontological attitude (NOA).

In The Philosophy of Manners Peter Johnson makes a compelling case for manners as a subject for investigation by modern moral philosophy. He examines manners as 'little virtues', explaining their distinctive conceptual characteristics and charting their intricate detail and relationships with each other. In demonstrating why manners are important to our mutual expectations, Johnson reveals a terrain which modern moral philosophy has left largely unmapped. Through a critical examination of the ethics of John Rawls and Alasdair MacIntyre, (...) Johnson shows how the nature of manners constitutes a philosophical problem both for liberalism and its critics. Taking the recent revival of virtue ethics as its broad starting point, The Philosophy of Manners discusses the 'little virtues' as they are treated in the Aristotelian and Kantian traditions of writing on ethics. Original features of the book include discussions of nameless virtues, the logical intricacy of the 'little virtues' which compose manners, and the nature of their orchestration by the more substantial virtues and moral concerns. The aim throughout is to give manners a philosophically defensible place in the moral life - a place which neither inflates nor understates their importance. --an examination of why manners are essential to moral literacy and an ethical society --the first work of its kind - no other ethical investigation concentrates on manners --relevant to the recent revival of interest in virtue ethics and any course in contemporary ethics --will provoke argument and disagreement.

Consequence rleations over sets of "judgments" are defined by using "overdetermined" as well as "underdetermined" valuations. Some of these relations are shown to be categorical. And generalized soundness and completeness results are given for both multiple and single conclusion consequence relations.

Frames of Deceit is a philosophical investigation of the nature of trust in public and private life. It examines how trust originates, how it is challenged, and how it is recovered when moral and political imperfections collide. In politics, rulers may be called upon to act badly for the sake of a political good, and in private life intimate attachments are formed in which the costs of betrayal are high. This book asks how trust is tested by human goods, moral (...) character and power relations. It explores whether an individual's experience of betrayal differs totally from that of a community when it loses and then seeks to recover a vital public trust. Although this is a work of political philosophy it is distinctive in examining three literary texts - Sophocles' Philoctetes, Shakespeare's Troilus and Cressida, and Zola's Thérése Raquin - in order to deepen our understanding of the place of trust in morality and politics.

With some justification, Michel Serres claimed that he was one of the first to make ecology a central question for philosophy. Many of his books explore the ecological emergency and spell out the need to include the more-than-human in any ethical and political response. Yet Serres’ thought has been generally neglected in scholarly debate outside France. To highlight the importance of Serres’ philosophy, I contrast aspects of his work with Latour’s sustained search for a political ecology. I contend that Serres’ (...) thought overlaps with but also challenges Latour’s approach that has increasingly turned for inspiration to the theory of Gaia proposed by Lovelock and Margulis. I argue that drawing from science, history, fables, the humanities and his own experience, Serres brings together a narrative of the commonality of all living and non-living things that exposes a contractable obligation and formulates the grounding for a new politics.

This article examines the arguments used by Robert Watts, a contemporary of John Stuart Mill, in his criticism of Mill's Utilitarianism. The pamphlet in which Watts expresses his views is a scarce and neglected work. Pioneering studies by J.C. Rees and J.B. Schneewind emphasize the importance of Mill's early critics for historians of nineteenth-century ethics and politial thought. Rees, however, confines his study to the responses to Mill's On Liberty. Schneewind's work is more comprehensive and does mention Watts, but without (...) examining in detail the actual arguments that Watts uses. Further, while Watts criticizes Mill's ethical views from a theological standpoint the arguments he uses are philosophical in character. Watts should not be thought of as a major philosophical critic of Mill, but his relative neglect leaves a gap in the study of the reception of Mill's thought which this article is intended to fill.

In this paper, I examine Oakeshott's account of civility by drawing on the porcupine metaphor that Oakeshott borrows from Schopenhauer. I explain why Oakeshott thinks that civility is best understood as a moral practice, one which has a special significance for politics. I outline the conceptual differences between civility understood as a small virtue and as an attribute of the civil condition. Three major difficulties in Oakeshott's treatment are raised. The first concerns his view that 'civil' is an adverbial qualifier; (...) the second concerns the relation between civility in its moral and its political senses, and the third is about the relation between civility and justice. While recognizing what is distinctive about Oakeshott's account, I indicate reservations about his discussion through a series of comparisons with Schopenhauer, and I conclude that, on their own terms, neither philosopher is able to solve the problem the porcupines set for them.

Why should modern philosophers read the works of R. G. Collingwood? His ideas are often thought difficult to locate in the main lines of development taken by twentieth-century philosophy. Some have read Collingwood as anticipating the later Wittgenstein, others have concentrated exclusively on the internal coherence of his thought. This work aims to introduce Collingwood to contemporary students of philosophy through direct engagement with his arguments. It is a conversation with Collingwood that takes as its subject matter the topics that (...) interested him 'philosophy and method, philosophy of mind, language and logic, the historical imagination, art and expression, action, metaphysics and life' and which still preoccupy us today. --the first introductory book on this major modern philosopher --includes critical investigation of his thought --there is no similar work available.

The argument of this article is that the Albert Memorial acted as a catalyst for some of Collingwood's most well known ideas in the philosophy of history and aesthetics. It was not, however, the exclusive source of those ideas, and indeed they had philosophical expression elsewhere. One may view his contemplations, then, as work in progress. For example, the logic of question and answer promoted by the Memorial was also prompted by Collingwood's reading of Bacon and Descartes. This was a (...) reflection of his determination to depart from the realism of his philosophical teachers. Similarly, the Memorial directs Collingwood's thought forward. The Memorial acts as a facilitator of his thought on history, which in the course of its formulation undergoes many transformations. The logic of question and answer also finds a place in Collingwood's early thinking about art, but even here it is in the process of constant transition. Collingwood's reaction to the Memorial helps us to conclude that there is nothing ironic about the fact that Collingwood loathed the structure that was also the instigator of one of his most influential philosophical doctrines.
