Essentialism is one of the most pervasive problems in mental health research. Many psychiatrists still hold the view that their nosologies will enable them, sooner or later, to carve nature at its joints and to identify and chart the essence of mental disorders. Moreover, according to recent research in social psychology, some laypeople tend to think along similar essentialist lines. The main aim of this article is to highlight a number of processes that possibly explain the persistent presence and popularity (...) of essentialist conceptions of mental disorders. One such process is the general tendency of laypeople to essentialize conceptual structures, including biological, social, and psychiatric categories. Another process involves the allure of biological psychiatry. Advocating a categorical and biological approach, this strand of psychiatry probably reinforced the already existing lay essentialism about mental disorders. As such, the question regarding why we essentialize mental disorders is a salient example of how cultural trends zero in on natural tendencies, and vice versa, and how both can boost each other.

Maladapting Minds discusses a number of reasons why philosophers of psychiatry should take an interest in evolutionary explanations of mental disorders and, more generally, in evolutionary thinking. First of all, there is the nascent field of evolutionary psychiatry. Unlike other psychiatrists, evolutionary psychiatrists engage with ultimate, rather than proximate, questions about mental illnesses. Being a young and youthful new discipline, evolutionary psychiatry allows for a nice case study in the philosophy of science. Secondly, philosophers of psychiatry have engaged with evolutionary (...) theory because evolutionary considerations are often said to play a role in defining the concept of mental disorder. The basic question here is: Can the concept of mental disorder be given an objective definition, or is it rather a normative concept? Thirdly and finally, evolutionary thinking in psychiatry has often been a source of inspiration for a philosophical view on human nature. Thus evolutionary psychiatrists have suggested, for example, that man's vulnerability to mental disorders may well be one of the defining features of our species. -/- Written by leading authors in philosophy, psychiatry, biology and psychology, this volume illustrates that many debates in contemporary philosophy of psychiatry are profoundly influenced by evolutionary approaches to mental disorders. Conversely, it also reveals how philosophers can help contribute to the burgeoning field of evolutionary psychiatry. It is important reading for a wide range of readers interested in mental health care and philosophy. (shrink)

In this article, we consider two independently appealing theories—the Growing-Block view and Humean Supervenience—and argue that at least one is false. The Growing-Block view is a theory about the nature of time. It says that past and present things exist, while future things do not, and the passage of time consists in new things coming into existence. Humean Supervenience is a theory about the nature of entities like laws, nomological possibility, counterfactuals, dispositions, causation, and chance. It says that (...) none of these entities are fundamental, since if they were, this would entail the existence of irreducible necessary connections between matters of fact. Instead, these entities supervene on a fundamental, non-nomological ‘Humean mosaic’ of property instances at spacetime points. We will further explain and motivate the Growing-Block view and Humean Supervenience in Sects. 2 and 3, but first, we turn to our master argument. (shrink)

Many physicists regard the flow of time as an illusion. There is an upper level flow of time, the phenomenon of past/present/future; and there is a lower level flow of time which is really a flow of events. Perceptual completion accounts for the lower level flow of time in a few ways: apparent movement; amodal completion; and dynamic change as exemplified by a newly described modal completion that we called happening. It acts like an illusory percept connecting discrete stimuli in (...) all sensory modalities. The past/present/future distinction cannot exist unless an object is perceived to be the same now as it is then. This cognition requires object persistence. Experiments with object persistence suggest the circumstances when that, too, is an illusory percept. The illusory percepts of object persistence and perceptual completion can account for the entire flow of time. Our findings and conclusions are congruent with a few time theories and cosmologies that suggest that the flow of time is an illusion. (shrink)

We show that five important elements of the ‘nomological package’— laws, counterfactuals, chances, dispositions, and counterfactuals—needn’t be a problem for the Growing-Block view. We begin with the framework given in Briggs and Forbes (in The real truth about the unreal future. Oxford studies in metaphysics. Oxford University Press, Oxford, 2012 ), and, taking laws as primitive, we show that the Growing-Block view has the resources to provide an account of possibility, and a natural semantics for non-backtracking causal counterfactuals. (...) We show how objective chances might ground a more fine-grained concept of feasibility, and furnished a places in the structure where causation and dispositions might fit. The Growing-Block view, thus understood, provides the resources to explain the close link between modality and tense, so that it predicts modal change as time passes. This account lets us capture not only what the future might hold for us, and also what might have been. (shrink)

A central debate in philosophy and neuroscience pertains to whether PFC activity plays an essential role in the neural basis of consciousness. Neuroimaging and electrophysiology studies have revealed that the contents of conscious perceptual experience can be successfully decoded from PFC activity, but these findings might be confounded by post- perceptual cognitive processes, such as thinking, reasoning, and decision-making, that are not necessary for con- sciousness. To clarify the involvement of the PFC in consciousness, we present a synthesis of research (...) that has used intracranial electrical stimulation (iES) for the causal modulation of neural activity in the human PFC. This research provides compelling evidence that iES of only certain prefrontal regions (i.e., orbitofrontal cortex and anterior cingu- late cortex) reliably perturbs conscious experience. Conversely, stimulation of anterolateral prefrontal sites, often con- sidered crucial in higher-order and global workspace theories of consciousness, seldom elicits any reportable alterations in consciousness. Furthermore, the wide variety of iES-elicited effects in the PFC (e.g., emotions, thoughts, and olfactory and visual hallucinations) exhibits no clear relation to the immediate environment. Therefore, there is no evidence for the kinds of alterations in ongoing perceptual experience that would be predicted by higher-order or global workspace theories. Nevertheless, effects in the orbitofrontal and anterior cingulate cortices suggest a specific role for these PFC subregions in supporting emotional aspects of conscious experience. Overall, this evidence presents a challenge for higher-order and global workspace theories, which commonly point to the PFC as the basis for con- scious perception based on correlative and possibly confounded information.

The idea of food sovereignty has its roots primarily in the response of small producers in developing countries to decreasing levels of control over land, production practices, and food access. While the concerns of urban Chicagoans struggling with low food access may seem far from these issues, the authors believe that the ideas associated with food sovereignty will lead to the construction of solutions to what is often called the “food desert” issue that serve and empower communities in ways that (...) less democratic solutions do not. In Chicago and elsewhere, residents and activists often see and experience racial and economic inequalities through the variety of stores and other food access sites available in their community. The connections between food access, respect, and activism are first considered through a set of statements of Chicagoans living in food access poor areas. We will then discuss these connections through the work and philosophy of activists in Chicago centered in food sovereignty and food justice. Particular focus will be placed on Growing Power, an urban food production, distribution, and learning organization working primarily in Milwaukee and Chicago, and Healthy South Chicago, a community coalition focused on health issues in a working class area of the city.

To localize wheat ESTs on chromosomes, 882 homoeologous group 6-specific ESTs were identified by physically mapping 7965 singletons from 37 cDNA libraries on 146 chromosome, arm, and sub-arm aneuploid and deletion stocks. The 882 ESTs were physically mapped to 25 regions flanked by 23 deletion breakpoints. Of the 5154 restriction fragments detected by 882 ESTs, 2043 were localized to group 6 chromosomes and 806 were mapped on other chromosome groups. The number of loci mapped was greatest on chromosome 6B and (...) least on 6D. The 264 ESTs that detected orthologous loci on all three homoeologs using one restriction enzyme were used to construct a consensus physical map. The physical distribution of ESTs was uneven on chromosomes with a tendency toward higher densities in the distal halves of chromosome arms. About 43% of the wheat group 6 ESTs identified rice homologs upon comparisons of genome sequences. Fifty-eight percent of these ESTs were present on rice chromosome 2 and the remaining were on other rice chromosomes. Even within the group 6 bins, rice chromosomal blocks identified by 1-6 wheat ESTs were homologous to up to 11 rice chromosomes. These rice-block contigs were used to resolve the order of wheat ESTs within each bin. (shrink)

Engagement happens when academics and non-academics form partnerships to create mutual understanding, and then take action together. An example is the “value web” work associated with W. K. Kellogg Foundation’s Food Systems Higher Education–Community Partnership. Partners nationally work on local food systems development by building value webs. “Value chains,” a concept with considerable currency in the private sector, involves creating non-hierarchical relationships among otherwise disparate actors and entities to achieve collective common goals. The value web concept is extended herein by (...) separating the values of the web itself, such as the value of collaboration, from values “in” the web, such as credence values associated with a product or service. By sharing and discussing case examples of work underway around the United States, the authors make a case for employing the value webs concept to represent a strategy for local food systems development, specifically, and for higher education–community partnerships, generally.

The complex hexaploid wheat genome offers many challenges for genomics research. Expressed sequence tags facilitate the analysis of gene-coding regions and provide a rich source of molecular markers for mapping and comparison with model organisms. The objectives of this study were to construct a high-density EST chromosome bin map of wheat homoeologous group 2 chromosomes to determine the distribution of ESTs, construct a consensus map of group 2 ESTs, investigate synteny, examine patterns of duplication, and assess the colinearity with rice (...) of ESTs assigned to the group 2 consensus bin map. A total of 2600 loci generated from 1110 ESTs were mapped to group 2 chromosomes by Southern hybridization onto wheat aneuploid chromosome and deletion stocks. A consensus map was constructed of 552 ESTs mapping to more than one group 2 chromosome. Regions of high gene density in distal bins and low gene density in proximal bins were found. Two interstitial gene-rich islands flanked by relatively gene-poor regions on both the short and long arms and having good synteny with rice were discovered. The map locations of two ESTs indicated the possible presence of a small pericentric inversion on chromosome 2B. Wheat chromosome group 2 was shown to share syntenous blocks with rice chromosomes 4 and 7. (shrink)

One of the most attractive aspects of food and agricultural studies for scholars is the level of public interest in the subjects of our research. Such interest means that food and agriculture scholars often become public scholars, asked to comment on issues of great interest to the public. In addition, food and agriculture scholars often have the opportunity to partner more directly with community organizations to perform community-based research. Such studies take many forms, but community members often take a lead (...) role, helping plan the study as well as participate in data collection and analysis. Community based research may be very rewarding, but scholars involved in such research need to deal with a lack of control that inevitably goes along with it. This article gives examples of such research and discusses the public role of food and agriculture studies in general, in particular highlighting what can be learned from public responses to a 2009 shortage of Eggo waffles.

In the early twentieth century, many philosophers in America thought that time should be taken seriously in one way or another. George P. Adams (1882-1961) argued that the past, present and future are all real but only the present is actual. I call this theory ‘actualist eternalism’. In this paper, I articulate his novel brand of eternalism as one piece of his metaphysical system and I explain how he argued for the view in light of the best explanations of temporal (...) experience and the present. I argue that his exploitation of analogies between time and modality offer some lessons for current debates about time such as the importance of providing a temporal epistemology. I also extract what I call the temporal boundary problem and argue that it gives rise to an unaddressed challenge for presentists and growing block theorists. (shrink)

In this article, drawing on the discursive psychology of Rom Harré, we show how mapping the exchange of words among people might disclose a complex reality; not merely that which farmers explicitly talk ‘about’ but the reality implicitly at stake within the communication. More specifically, we show how discourses involving modern farmers reveal an underlying placing in an abstract space, having sub-spaces defined by the life-orientation, sense of self and according self-positioning of modern people. In this way, we construct a (...) road map of a set of ‘individualities’ characterizing the life of modern farmers: an individuality of citizenship, an individuality of geographies and an individuality of experience. Consequently, farmers face the problem that this multiplicity of individuality prevents them from communicating, as we will call it, univocally in the public by contrast to the univocal voices of other established social groups. We will analyse the structure of that problem by viewing diverse relations between the authority and the authenticity of different partners in the conversation on land use. (shrink)

Transoral laser microsurgery applies to the piecemeal removal of malignant tumours of the upper aerodigestive tract using the CO2 laser under the operating microscope. This method of surgery is being increasingly popularised as a single modality treatment of choice in early laryngeal cancers (T1 and T2) and occasionally in the more advanced forms of the disease (T3 and T4), predomi- nantly within the supraglottis. Thomas Kuhn, the American physicist turned philosopher and historian of science, coined the phrase ‘paradigm shift’ in (...) his groundbreaking book The Structure of Scientific Revolutions. He argued that the arrival of the new and often incompatible idea forms the core of a new paradigm, the birth of an entirely new way of thinking. This article discusses whether Steiner and col- leagues truly brought about a paradigm shift in oncological surgery. By rejecting the principle of en block resection and by replacing it with the belief that not only is it oncologically safe to cut through the substance of the tumour but in doing so one can actually achieve better results, Steiner was able to truly revolutionise the man- agement of laryngeal cancer. Even though within this article the repercussions of his insight are limited to the upper aerodigestive tract oncological surgery, his willingness to question other peoples’ dogma makes his contribution truly a genuine paradigm shift.

The complicated colonial history of the Philippines impacts notions of gender in the Islands. Specifically, institutions with strong foreign roots, such as universities, maintain and challenge gender relations. The Philippines sees multiple gender issues in universities despite government-mandated gender mainstreaming policies for education (CMO-1), yet the influence of colonial values remains overlooked. This article contributes to philosophising Philippine education by providing the history of the country’s universities and their role in shaping gender relations. A threefold model of gender structures, relations (...) of power, production and cathexis (emotional attachment), frames historical literature during the Philippines’ Spanish and American colonial periods and contextualises the country’s gender order. The interplay of religion and higher education during the Philippines’ Spanish colonial period reveals why sexuality remains policed by education institutions. The gendering of courses during the American Colonial period details the feminisation of certain disciplines and occupations. Harmful manhood practices adopted during this period continue to affect men in university systems through Philippine fraternities. Lastly, private education perpetuates and maintains power among the elite. The evolution of the Philippine university provides points for analysis for gender issues. These become building blocks to the discourse surrounding the Filipino philosophy of education, by understanding facets of Filipino identity construction, and proposing avenues to explore when decolonising the university.

There are two broad classes of empirical theories of consciousness, which I will call the biological and the functional. The biological approach is based on empirical correlations between experience and the brain. For example, there is a great deal of evidence that the neural correlate of visual experience is activity in a set of occipetotemporal pathways, with special emphasis on the infero-temporal cortex. The functionalist approach is a successor of behaviorism, the view that mentality can be seen as tendencies to (...) emit certain behavioral outputs given certain sensory inputs. The trouble with behaviorism is that it did not allow that mental states were causes and effects, but functionalists do allow this. They characterize consciousness in terms of its causal role: the causal influence on it from inputs and other mental states, and its causal efficacy with respect to other mental states and behavior. The central idea of functionalism is a proposal about the concept of consciousness, but scientific functionalists have filled the view in with empirical details—the idea is that a representation is conscious if it is broadcast in a global neuronal workspace. The functional approach says consciousness is a role, whereas the biological approach says consciousness is a realizer of that role. For example, one could take solubility to be a role—dissolving in certain circumstances—or, as with the biological view of consciousness, the physico-chemical configuration that has that role. The.

High-frequency oscillations emerged as a neural code for both positive affect and fluent attentional processing from evolutionary simulations with artificial neural networks. Visual 50 Hz flicker, which entrains neural oscillations in the gamma band, has been shown to foster attentional switching, but can it also elicit positive affect? A three-faces display was preceded by a 50, 25, or 0 Hz flicker on the position of the odd-one-out. Participants decided on the gender or on the subjective valence of this neutral target (...) in an approach-avoidance task, which served as an implicit affective measure. Only the detection of 25 Hz flicker, but not of 50 Hz flicker, was above chance. Faces primed by invisible 50 Hz flicker were explicitly evaluated more positively than with 25 Hz or 0 Hz. This gamma flicker also facilitated approach reactions, and inhibited avoidance reactions relative to 25 Hz and 0 Hz flicker in Blocks 1 and 2. Attentional switching was, moreover, enhanced by the 50 Hz flicker. According to the Affect–Gamma hypothesis, also in biological neural networks, high-frequency gamma oscillations may code for positive affect. (shrink)

Dedicated to Philipp Frank and containing introductory greetings to Frank by some of his more illustrious pupils and colleagues, the essays in this volume cover the proceedings of the Boston Colloquium for the Philosophy of Science, 1962-1964. The essays deal with most of the important problems in the philosophy of science from physics to the biological sciences and psychology, and include approaches from diverse traditions: Whiteheadian, Scientific Realism, Thomistic, Phenomenological, as well as historical approaches. High points were McMullin's "From Matter (...) to Mass," which contained a highly sensitive analysis of the Aristotelian doctrine of prime matter; Sellars's "The Identity Approach to the Mind-Body Problem"; Capek's "The Myth of Frozen Passage," which very ably took to task some historical and theoretical overextensions of Relativity Theory and spatializations of time which have resulted in the Block-Universe theory: the fact that Donald Williams commented on Capek's paper made it all the more interesting as it was William's theory in particular that was under attack. The best part of the book, however, was an approximately one hundred page exchange on the nature of scientific explanation which included a lead paper by J. J. C. Smart and lengthy commentaries by Sellars, Putnam, and Feyerabend. The issue, in part, was the radical-replaceability-of-frameworks theory of Feyerabend versus the gradual-replacement theory of Sellars.—E. A. R. (shrink)

Quel bon vent, quel joli vent, ma vie m’appelle, ma vie m’attend French folk song 1. Presentists and Growing Block theorists appeal to ‘powerful intuitions’ when they defend their respective conceptions of time . Eternalists are prepared to go some length towards ‘reconciling’ the view from nowhen with at least some of these intuitions, or try to explain them away . Unaided intuitions may in fact underdetermine any particular metaphysical choice. One set of intuitions about time seems to have (...) been neglected, though, in spite of its power. These intuitions are the mirror image of those supporting the Growing Block theory , and they are modelled on a pre-reflective understanding of our own life. According to the intuitions, only the future and the present are real; the past isn’t. The present is the constantly eroding edge of the future, which thus shrinks incessantly. There is less and less future as the present proceeds. The obvious intuitive model of this view of time is our life; from which every day eats up a little bit. Smaller scale models are available in everyday life. As you are reading this text, you have less and less to read. You know it. You know that at some point you’ll finish, or stop, reading it. But a model is not enough to make a grand philosophical claim, and indeed the very existence of the model is the ground for a negative claim: a picture, it may be said, is holding you captive. The Future Shrinker has two tasks. The first is to show that the intuitive picture supporting the claim is robust and does not make implausible epistemological claims. The second task is to show that her theory is at least compatible with scientific lore, and at best a good way …. (shrink)

In England, Wales and Scotland, the vast majority of abortions take place in the first trimester of pregnancy. In 2009, for example, 91% of abortions were carried out at under 13 weeks gestation for women resident in England and Wales. 1 Early abortion opens up the opportunity for a woman to have a medical abortion rather than a surgical abortion. Medical abortion is considered to be less invasive and less expensive than surgical abortion, and is increasingly becoming the preferred method. (...) 1 The proportion of medical abortions to surgical abortions has doubled in the last five years with 52% of abortions being medical abortions under 9 weeks gestation in 2009. A medical abortion typically involves taking mifepristone to block the hormones that help a pregnancy to continue, and then later on misoprostol, which makes the womb expel the embryo/fetus, usually within 4–6 h. Current legislation requires that both sets of drugs are administered in an NHS hospital or approved place, but women can go home after taking the second dose of drugs to complete the abortion. There has long been disagreement between the Department of Health and the British Pregnancy Advisory Services about what constitutes ‘any treatment for the termination of pregnancy’ under the Abortion Act 1967, specifically whether a woman taking the second set of drugs is considered to be undergoing the ‘treatment’ and is therefore required to be present in premises permitted under the Act. At the end of 2010, BPAS went to the High Court to challenge the Department of Health's view that the legislation requires women to take both sets of drugs in an approved place. BPAS argued that ‘treatment’ stops at the point of prescription and women should be able to go home, …. (shrink)

Nietzsche’s perspectivism has received restricted and unrestricted interpretations. The latter take the cognitive effects of ‘perspectives’ to be pervasive and general; the former argue they are restricted to special subject matters, have limited effects, or are not essentially cognitive at all. I argue on textual grounds that Nietzsche was committed to the unrestricted view. Comparison to A.W. Moore’s treatment of perspectival representation in Points of View illuminates both the nature of perspectivism and key arguments needed to defend it. Nietzschean perspectivism (...) must deny the very possibility of absolute representations (sensu Moore), and to do so, it must block a form of argument that promises to integrate perspectival representations into progressively less restricted, and ultimately absolute, representations of the world. Such arguments depend on a strong assumption about the unity of the independent world, which Moore accepts and Nietzsche denies. Nietzsche’s pluralism about perspectives thereby turns out to rely on pluralism about the world, which shapes his understanding of us as essentially bounded cognitive agents. Nietzsche holds that the longing for absolute representation manifest in Moore, Leibniz, and many other philosophers, which aspires to overcome the limitations of perspective, amounts to ascetic self-denial about our cognitive condition.

A unifying theory of general anesthetic-induced unconsciousness must explain the common mechanism through which various anesthetic agents produce unconsciousness. Functional-brain-imaging data obtained from 11 volunteers during general anesthesia showed specific suppression of regional thalamic and midbrain reticular formation activity across two different commonly used volatile agents. These findings are discussed in relation to findings from sleep neurophysiology and the implications of this work for consciousness research. It is hypothesized that the essential common neurophysiologic mechanism underlying anesthetic-induced unconsciousness is, as with (...) sleep-induced unconsciousness, a hyperpolarization block of thalamocortical neurons. A model of anesthetic-induced unconsciousness is introduced to explain how the plethora of effects anesthetics have on cellular functioning ultimately all converge on a single neuroanatomic/neurophysiologic system, thus providing for a unitary physiologic theory of narcosis related to consciousness.

Ethics and Decision Making in Counseling and Psychotherapy has a distinct and timely focus on counseling as a profession. Chapters address the mental health professions, values in counseling, decision making, ethical principles, ethical standards, technology, ethical climate, and office/administrative practices. The early chapters present a foundation for ethical practice of the profession and provides solid building blocks to the more advanced perspectives in later chapters. Chapters on specialty practice are lively and contemporary overviews of these practice areas in counseling that (...) reflect more recent trends to increased differentiation of these areas of practice. Each specialty has its own chapter to allow for an extended discussion of the unique aspects of the field that provide clarity to understanding the particular ethical issues and standards that apply in each specialty. The specialty areas recognized by CACREP are included: mental health counseling; school counseling; couple, marital, and family counseling; rehabilitation counseling; addictions counseling; career counseling; and group counseling. This book is broad in its coverage of the most practiced specialties in mental health practice, and provides an efficient and effective overview of the broad scope of particular areas addressed in counseling.

The Democratic Republic of the Congo is facing two crises: a potentially explosive Ebola epidemic and a major insurgency. But they are not wholly distinct from each other: the first is intertwined with the second, and public mistrust and political violence add a dangerous dimension to the Ebola epidemic. The World Health Organization and other health emergency responders will increasingly find themselves fighting outbreaks in insecure, misgoverned or ungoverned zones, possibly experiencing active conflict. Yet the WHO has neither the mission (...) nor the capabilities to navigate these security threats. We cannot expect that the usual public health strategy will succeed when health workers’ lives are directly imperiled and community resistance runs deep. Tackling health emergencies amidst complex humanitarian crises requires fresh thinking. Here, we offer a blueprint for fighting diseases in complex humanitarian emergencies. The building blocks of security and trust include high‐level political support, street‐level diplomacy, community engagement, enhanced funding, and protection of health professionals working in conflict or disaster zones.

Agroecology has been proposed as a key building block for food sovereignty. This article examines the meaning, practices and potentials of ‘transformative agroecology learning’ as a collective strategy for food system transformation. Our study is based on our qualitative and action research with the European Coordination of Via Campesina to develop the European Agroecology Knowledge Exchange Network. This network is linked to the global network of La Via Campesina and builds on the strong experiences and traditions of popular education (...) in Latin American peasant movements. Rather than focusing on agroecology education as a process of individual learning, we analyse how a transformative agroecology education can be strengthened as a critical repertoire of action used by social movements to advance food sovereignty. Our analysis contributes a new theory of transformative agroecology learning based on four key characteristics or qualities: horizontalism; diálogo de saberes ; combining practical and political knowledge; and building social movement networks. While these different elements of transformative agroecology learning were present across EAKEN, they were unevenly developed and, in many cases, not systematized. The framework can help to strategically and reflexively systematize and strengthen a transformative agroecology learning approach as a key building block for food sovereignty. (shrink)

One major milestone in the development of the sea urchin embryo is the assembly of a single cilium on each blastomere just before hatching. These cilia are constructed both from pre‐existing protein building blocks, such as tubulin and dynein, and from a number of 9+2 architectural elements that are synthesized de novo at ciliogenesis. The finite or quantal synthesis of certain key architectural proteins is coincident with ciliary elongation and proportional to ciliary length. Upon deciliation, the synthesis of architectural proteins (...) occurs anew, a new cilium grows, and the stores of various building blocks are replenished. This routine of coordinated ciliary gene expression may be replayed experimentally many times without delaying normal development. The ability to regenerate cilia has allowed elucidation of these various protein synthetic relationships and has led to the discovery of the pathways by which membrane‐associated tubulin and axoneme‐associated architectural proteins are conveyed into the highly compartmentalized growing cilium. The sea urchin embryo thus provides a very convenient model system for studies of ciliary assembly and maintenance, coordinate gene expression and membrane dynamics. (shrink)

Loyalty, by making us identify with others, takes us beyond the very limited self (roughly the self of the Hobbesian natural condition) that is involved in selfishness and that is usually involved when people consider that self-concern, that aspect of human nature that must be limited if we are to live peaceably, is the main stumbling block to morality. Loyalty can thus be thought of as a version of altruism, as an inclination to identify with others and to share (...) their good. That is to say, loyalty seems opposed to the troublesome aspects of self-concern. We would, nevertheless, be mistaken to conclude that it must simply be a good in people, something to be encouraged. The primary issue is: Which loyalties should be encouraged? There is no general truth about the value of loyalty as such. (shrink)

To all appearances, the basic building blocks of reality tend to keep existing unless something intervenes to destroy them. In other words, basic things seem to have existential inertia.

In a recent essay review of William R. Newman, Atoms and Alchemy (2006), Ursula Klein defends her position that philosophically informed corpuscularian theories of matter contributed little to the growing knowledge of "reversible reactions" and robust chemical species in the early modern period. Newman responds here by providing further evidence that an experimental, scholastic tradition of alchemy extending well into the Middle Ages had already argued extensively for the persistence of ingredients during processes of "mixture" (e.g. chemical reactions), and that (...) this corpuscular alchemical tradition bore important fruit in the work of early modern chymists such as Daniel Sennert and Robert Boyle.

Improvement in performance after the end of the training session, termed “Offline improvement,” has been shown in procedural learning tasks. We examined whether Offline improvement in learning a novel orthography depends on the type of reading instruction. Forty-eight adults received multisession training in reading nonsense words, written in an artificial script. Participants were trained in one of three conditions: alphabetical words preceded by direct letter instruction (Letter-Alph); alphabetical words with whole-word instruction (Word-Alph); and nonalphabetical (arbitrary) words with whole-word instruction (Word-Arb). (...) Offline improvement was found only for the Letter-Alph group. Moreover, correlation with a standardized measure of word reading ability showed that good readers trained in the Letter-Alph group exhibit greater Offline improvement, whereas good readers trained in the Word-Arb group showed greater Within-session improvement during training. These results suggest that different consolidation processes and learning mechanisms were involved in each group. We argue that providing a short block of direct letter instruction prior to training resulted in increased involvement of procedural learning mechanisms during training. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 12.4 (2005) 325-329 [Access article in PDF] Psychoanalysis as Natural Philosophy R. D. Hinshelwood Keywords evolution, psychopathology, ethics, unconscious phantasy Andreas De Block has offered us a most fascinating paper. We do not have to agree with all his points to be profoundly stimulated by them. His core proposition is that Freud pathologizes ordinary psychology and personalities, as well as the abnormal. There has (...) been a perennial debate about whether, psychoanalytically speaking, there is a continuum from pathology to normality or if there is a discontinuity at some point between the two. Freud's famous quote—"much will be gained if we succeed in transforming your hysterical misery into common unhappiness" (Breuer and Freud 1895, 305)—is ambiguous. Interestingly, De Block takes a hard stand on this; he not only assumes a continuum, but further he reads Freud as saying that all normality is neurotic. This is not a usual reading of Freud. De Block then expands this into a philosophical position. It is, he says, Freud's philosophy on the nature of mind.Freud himself was not interested in philosophy, and thought it largely irrelevant to psychoanalysis. In fact, he mused about the traffic being inevitably in the opposite direction—that philosophy might come to psychoanalysis. In discussing the work of a philosophically inclined analyst, he remarked, The decisive reason for the rejection of Putnam's proposals was the doubt as to which of the countless philosophical systems should be accepted, since they all seem to rest on an equally insecure basis.... It seemed more prudent to wait, and to discover whether a particular attitude towards life might be forced upon us with all the weight of necessity by analytical investigation itself. (Freud 1921, 270) Psychoanalysis, Freud thought, might be the very substance from which a philosophical system could emerge. De Block has followed that route; he has gone to Freud's writing to discovery a weltanshaung on which we might develop a philosophy of life. He has come back from his intellectual expedition with Freud's fascinating paper, published only in 1987 (discovered in 1983), "A Phylogenetic Phantasy." This was actually written in 1914, but Freud never published it and in fact destroyed his own copy of the draft. The paper has been called a "metabiology" (Gubrich-Simitis 1987), and deals with Freud's speculation on how a threatened species during the ice age developed certain biological and biopsychological traits1 necessary to survive the harsh environmental conditions. These traxits, which included the repression of libido, had significant side effects, namely, the pathologies arising from repression: the neuroses, perversions and psychoses. Moreover, today the environmental conditions no longer apply, so we are left with the side effects of traits that are no longer biologically useful. [End Page 325]So, De Block indicates at least the possibility of an evolutionary theory of the nature of mind. Even if Freud's Lamarckianism makes his particular speculative metabiology implausible, it is a way of thinking that suggests that a theory of mind can arise from biological understanding of its evolutionary development. However, De Block goes further. As a corollary, because Freud's view of the evolution of mind is to involve the evolutionary nature of psychopathology, then Freud's psychoanalysis can suggest an evolutionary psychiatry—that is to say, psychiatry can look for distant causes of mental disturbance in the vagaries of evolutionary influence.This way of approaching philosophy is interesting because it starts with the outcome of a scientific investigation of the human mind, just as Freud suggested in the passage quoted (Freud 1921, 270). The prospect is for a natural philosophy of mind, just as the physics of fundamental particles and the "big bang" prompt us toward a kind of natural ontology of the universe and its contents, arising from empirically tested facts.However, De Block is on rather uncertain ground with the evidence for his argument; he commits Freud to this biological speculation on the basis of a paper that Freud did not in fact publish and tore up.2 Even if Freud's reading of the evolutionary origins of man...

One popular style of argument for the thesis that determinism is incompatible with moral responsibility features manipulation. Its thrust is that regarding moral responsibility, there is no important difference between various cases of manipulation in which agents who A are not morally responsible for A-ing and ordinary cases of A-ing in deterministic worlds. There is a detailed argument of this kind in Derk Pereboom’s recent book (2001: 112–26). His strategy in what he calls his ‘four-case argument’ (117) is to describe (...) three cases of progressively weaker manipulation in which, he contends, the agent, Plum, is not morally responsible for killing his victim and to compare them to a related deterministic case that involves no manipulation. Pereboom argues that what blocks Plum’s moral responsibility for the killing in the first three cases is the fact that ‘his action results from a deterministic causal process that traces back to factors beyond his control’ and that, because this fact also obtains in the fourth case, Plum is not morally responsible for that killing either (116). My thesis is that Pereboom’s argument fails. (shrink)

In this short paper, we respond to critics of our original paper, The agony of agonal respiration: is the last gasp necessary?. A common thread in both Hawryluck’s and Kuhse’s responses is the difficulties encountered when using the agent’s intentions to make moral distinctions between using neuromuscular blocking drugs to palliate versus using neuromuscular blocking drugs to kill. Although this difficulty does exist we maintain that the intentions of the physician must matter when providing end-of-life care.

A blatant contradiction seems to characterize the first part of DA II 12: 424a24-25 entails that possession of the power to ‘receive forms without the matter’ is sufficient for being a sense organ, while the ‘wax simile’ supposedly preceding it (424a19-23) attributes the same power to both senses and wax blocks. To solve the contradiction, I contend that Aristotle does not in fact endorse the described ‘wax simile’. He offers, instead, a ‘signature simile’ between the forms received by senses and (...) the analogously matterless signatures transmitted by signet rings. This reading is supported by the use of the clause ‘forms without matter’ in Aristotle’s Corpus, which consistently refers to causally powerless and metaphysically sterile abstractions. I accordingly contend that the reception of perceptible forms without matter only describes the mental dimension of perception, and that the idea has no implications whatsoever with regard to physiology. The resulting attempt at capturing the mental aspect of perception is original and philosophically interesting: no unanalysable opposition of the mental to the physical is postulated, and currently crucial notions like ‘consciousness’ or ‘intentionality’ are playing no role at all.

Over the past decade, there has been an extensive debate about whether researchers have an obligation to disclose genetic research findings, including primary and secondary findings. There appears to be an emerging (but disputed) view that researchers have some obligation to disclose some genetic findings to some research participants. The contours of this obligation, however, remain unclear. -/- As this paper will explore, much of this confusion is definitional or conceptual in nature. The extent of a researcher’s obligation to return (...) secondary and other research findings is often limited by reference to terms and concepts like “incidental,” “analytic validity,” “clinical validity,” “clinical relevance,” “clinical utility,” “clinical significance,” “actionability,” and “desirability.” These terms are used in different ways by different writers to describe obligations in different sorts of cases. -/- Underneath this definitional confusion is a general notion, supported by much of the literature, that findings only need to be disclosed when they surpass certain presumably objective or measureable thresholds, such as medical importance or scientific reproducibility. The problem is that there is significant variability in the way that these terms and concepts are used in the literature and, as such, in defining the scope of an obligation to return findings that surpasses the relevant thresholds. -/- The goal of this paper is to analyze the definitional muddle underlying the debate about returning genetic research findings, with the hope of answering a few questions. First, what is the range of definitions being used in this debate? Based on an extensive literature review, Part 1 will lay out a range of articulated definitions for each relevant term, with the goal of categorizing them into a handful of distinct types. Part 2 explains the definitional redundancy and confusion in the current literature, and, drawing from the terminological patterns identified in Part 1, outlines more cohesive building blocks to inform the development of future disclosure frameworks.Our minimum goal in articulating these conceptual building blocks is to promote clearer articulations of, and distinctions between, future disclosure frameworks. More ambitiously, we suggest which definitions and conceptualizations we consider most appropriate to use in future disclosure frameworks. Here, we seek to balance benefits to participants through the disclosure of important information with the minimization of undue burdens on individual researchers and the research enterprise more generally. -/- Our analysis builds upon the central philosophical distinction between concepts and conceptions. The basic idea is that the “concept” of X refers to the general (and relatively uncontroversial) structure/shape of X, while various “conceptions” of X are more particular, filled out, and controversial elaborations of the concept. In other words, “concepts” of X will be formal representations of X, while “conceptions” of X will be substantive interpretations of the key elements and relationships operating within that formal framework. (Implicit in this distinction is an important point about the nature of disagreement – namely, that in order for two or more parties to “disagree” about X as opposed to simply talk past one another, there must be at least enough shared agreement about X to know that the parties are referring to the same thing. A concept of X provides this point of common agreement, while competing conceptions of X mark the areas where disagreement arises.) In this paper, we will employ this distinction in a fundamental way to clarify exactly where the primary disagreements arise in the debate over disclosing genetic research findings. -/- We propose that, underlying all the seeming confusion and disagreement, there are three central and widely agreed upon concepts at work in this debate—validity, value, and volition. The first two concepts concern the nature of the information itself. An obligation to disclose only exists when findings are valid and have value but there are competing conceptions of how to determine or define validity and valuableness. The third concept—volition—pertains not to the information but rather to the person to whom it will be disclosed. Does that person want or not want the information, and what is the best way of determining this? Here, too, competing conceptions arise. Our key point, though, is that almost all of the ethical disagreement arises because of competing conceptions of these three concepts. Understanding and appreciating this key point can help to refocus the substantive debate by providing some common ground to start from in determining how best to interpret these shared concepts. This refocusing can, ideally, produce more productive debate and facilitate some progress in resolving it. (shrink)

Questions about the naturalness or unnaturalness of homosexuality are as old as the hills, and the answers have often been used to condemn homosexuals, their behaviors, and their relationships. In the past two centuries, a number of sciences have involved themselves in this debate, introducing new vocabularies, theories, arguments, and data, many of which have gradually helped tip the balance toward tolerance and even acceptance. In this book, philosophers Pieter R. Adriaens and Andreas De Block explore the history and (...) philosophy of the gay sciences, revealing how individual and societal values have colored how we think about homosexuality. The authors unpack the entanglement of facts and values in studies of male homosexuality across the natural and human sciences and consider the extent to which science has mitigated or reinforced homonegative mores. The focus of the book is on homosexuality's assumed naturalness. Geneticists rephrased naturalness as innateness, claiming that homosexuality is innate-colloquially, that homosexuals are born gay. Zoologists thought it a natural affair, documenting its existence in myriad animal species, from maybugs to men. Evolutionists presented homosexuality as the product of natural selection and speculated about its adaptive value. Finally, psychiatrists, who had initially pathologized homosexuality, eventually appealed to its naturalness or innateness to normalize it. Discussing findings from an array of sciences--comparative zoology, psychiatry, anthropology, evolutionary biology, social psychology, developmental biology, and machine learning--this book is essential reading for anyone interested in what science has to say about homosexuality.

Many scholars view political contractarianism as a distinctly modern account of the foundations of political order. Ideas such as popular sovereignty, the right of revolution, the necessity of the consent of the governed for rightful political authority, natural equality, and a pre-civil state of nature embody the modern rupture with classical political philosophy and traditional Christian theology. At the headwaters of this modern revolution stands Thomas Hobbes. Since the American founders subscribed to the social contract theory, they are often said (...) to reject classical political philosophy and traditional Christian political theology as well. In America on Trial, Robert Reilly rejects the usual argument. He maintains that the building blocks of the American founding originate in medieval Christian political theology. In this essay, I argue that a morally and metaphysically realist contractarian tradition—one that affirms natural equality, the authority of the society over government, the necessity of consent for legitimate government, the right to resist tyrannical rulers, and the idea of a pre-civil state of nature—predates Hobbes and also that the voluntarist contractarian tradition inaugurated by Hobbes is self-referentially incoherent. A coherent political contractarianism logicially depends on the sort of metaphysics and moral ontology Hobbes rejects. (shrink)

Two key research issues in the field of causal learning are how people acquire causal knowledge when observing data that are presented sequentially, and the level of abstraction at which learning takes place. Does sequential causal learning solely involve the acquisition of specific cause-effect links, or do learners also acquire knowledge about abstract causal constraints? Recent empirical studies have revealed that experience with one set of causal cues can dramatically alter subsequent learning and performance with entirely different cues, suggesting that (...) learning involves abstract transfer, and such transfer effects involve sequential presentation of distinct sets of causal cues. It has been demonstrated that pre-training can modulate classic causal learning phenomena such as forward and backward blocking. To account for these effects, we propose a Bayesian theory of sequential causal learning. The theory assumes that humans are able to consider and use several alternative causal generative models, each instantiating a different causal integration rule. Model selection is used to decide which integration rule to use in a given learning environment in order to infer causal knowledge from sequential data. Detailed computer simulations demonstrate that humans rely on the abstract characteristics of outcome variables to select a causal integration rule, which in turn alters causal learning in a variety of blocking and overshadowing paradigms. When the nature of the outcome variable is ambiguous, humans select the model that yields the best fit with the recent environment, and then apply it to subsequent learning tasks. Based on sequential patterns of cue-outcome co-occurrence, the theory can account for a range of phenomena in sequential causal learning, including various blocking effects, primacy effects in some experimental conditions, and apparently abstract transfer of causal knowledge.

At 195B 9 it is pointed out that the Wax Block theory does not cover that large class of judgments in which no sense-objects are concerned, e.g. judgments about numbers. How can we make the mistake of judging that 7 + 5 = 11?The simile of the Aviary, now introduced, is very simple. It illustrates the difference between potential knowledge and actual knowledge, i.e. between knowledge at our disposal, because it has been learnt and stored away in the mind, (...) and knowledge present and ‘alive’ at the moment. The theory is that when we make a mistake about the sum of 7 and 5 we are ‘hunting for’ the knowledge of 12, which we ‘possess’ as we might possess a bird in a cage, but which we have not ‘got about us’ ; but we mis-take, wrongly take our knowledge of 11, i.e. we call up before our mind a different piece of knowledge.

Skeptical theism, broadly construed, is an attempt to leverage our limited cognitive powers, in some specified sense, against “evidential” and “explanatory” arguments from evil. Since there are different versions of these kinds of arguments, there are correspondingly different versions of skeptical theism. In this paper, I briefly explain three versions of these arguments from evil (two from William Rowe and one from Paul Draper) and the three versions of skeptical theism tailor-made to block them (from Stephen Wykstra, Michael Bergmann, (...) and Peter van Inwagen).
