Natural selection is commonly interpreted as the fundamental mechanism of evolution. Questions about how selection theory can claim to be the all-sufficient explanation of evolution often go unanswered by today's neo-Darwinists, perhaps for fear that any criticism of the evolutionary paradigm will encourage creationists and proponents of intelligent design.In Biological Emergences, Robert Reid argues that natural selection is not the cause of evolution. He writes that the causes of variations, which he refers to as natural experiments, are independent of (...) natural selection; indeed, he suggests, natural selection may get in the way of evolution. Reid proposes an alternative theory to explain how emergent novelties are generated and under what conditions they can overcome the resistance of natural selection. He suggests that what causes innovative variation causes evolution, and that these phenomena are environmental as well as organismal.After an extended critique of selectionism, Reid constructs an emergence theory of evolution, first examining the evidence in three causal arenas of emergent evolution: symbiosis/association, evolutionary physiology/behavior, and developmental evolution. Based on this evidence of causation, he proposes some working hypotheses, examining mechanisms and processes common to all three arenas, and arrives at a theoretical framework that accounts for generative mechanisms and emergent qualities. Without selectionism, Reid argues, evolutionary innovation can more easily be integrated into a general thesis. Finally, Reid proposes a biological synthesis of rapid emergent evolutionary phases and the prolonged, dynamically stable, non-evolutionary phases imposed by natural selection. (shrink)

The Scottish Philosophy of Common Sense originated as a protest against the philosophy of the greatest Scottish philosopher. Hume's sceptical conclusions did not excite as much opposition as might have been expected. But in Scotland especially there was a good deal of spoken criticism which was never written; and some who would have liked to denounce Hume's doctrines in print were restrained by the salutary reflection that if they were challenged to give reasons for their criticism they would find it (...) uncommonly difficult to do so. Hume's scepticism was disliked, but it was difficult to see how it could be adequately met. At this point Thomas Reid stepped into the field. He was the only man of his time who really understood the genesis of Hume's scepticism and succeeded in locating its sources. At first sight it would seem that this discovery required no peculiar perspicuity. It would seem that nobody could help seeing that Hume's sceptical conclusions were based on Locke's premises, and that Hume could never be successfully opposed by any critic who accepted Locke's assumptions. But this is precisely one of those obvious things that is noticed by nobody. And in fact Reid was the first man to see it clearly. It thus became his duty to question the assumptions on which all his own early thought had been based. The result of this reflection was the conclusion that, since the "ideal theory" of Locke and Berkeley logically led to Hume's scepticism, and since scepticism was intolerable, that theory would have to be amended, or, if necessary, abandoned. This volume contains works by Thomas Reid, Adam Ferguson, James Beattie, and Dugald Stewart. (shrink)

Macphail’s (1985) null hypothesis challenged researchers to demonstrate any differences in intelligence between vertebrate species. Rather than focus on differences, we asked whether rats would show the same unexpected, counterintuitive features of skill learning observed in humans: Factors that degrade performance during acquisition often enhance performance in a subsequent retention/autonomy phase. Providing post-trial “knowledge of results” (KR) on 30%-67% of trials instead of 100% degrades accuracy, yet increases retention in a subsequent phase without KR. We tested this feature by providing (...) three groups of rats with KR on every trial (100% KR), 67% KR, or 0% KR. We also provided operant feedback in every trial for completing the left-right lever-press skill (food for correct sequences, timeout for all others). In the autonomy phase, we assessed their ability to complete the skill independently—in the absence of differential cues and KR feedback. In agreement with human performance in the autonomy phase, 67% KR yielded higher skill accuracy than providing 100% KR. Also, providing 67% KR improved skill accuracy above that observed with operant feedback alone (0% KR). Rather than degrading performance during acquisition, the 67% KR condition yielded unexpected higher accuracy than the other conditions. Accuracy increased systematically across our extended acquisition phase, which provided each rat with over 3600 trials compared to 20-30 trials for human studies. Providing limited KR promoted skill learning in rats as it does in humans, consistent with the conjecture that both species share common learning processes. Introducing difficulties to rats during training improved their autonomy. (shrink)

Quoted from Naomi Klein, No LogoThis paper argues for the importance of John Dewey's aesthetic philosophy to recent efforts to cultivate civic environmentalism while critiquing narrowly conservationist environmentalisms. We call for a strong version of civic environmentalism oriented towards holistic integration of ecological [End Page 74] concerns into all aspects of social, political, economic, and cultural life. Such a civic environmentalism argues that it is not enough to strive to preserve enclaved 'wilderness' or 'biodiversity' (as important as that is). It argues also for fundamental changes in the political and economic status quo, because ecological havoc is understood to be integrally linked with the structural forces that are increasing inequality and weakening democratic publics. Strengthening of the civic commons is integral to protection of the environmental commons. If the environmental commons are the substantive goods in common which are the sustaining grounds of life, the civic commons are the institutions, collective memories, social networks, and skills that enable and inspire individuals to engage with each other in stewarding the common good. Such collective labor for the larger good requires some form of collective imagination which enables awareness of self and other (human or non-human) as inherently valuable. But beyond this, it requires perceptual and social infrastructures that nurture the ability to see self and other as emergent from and dependent on the supra-individual matrix that supports both life and individual. Central to such civic labor, is a non-dualistic understanding of individual/matrix. Such a non-dualistic understanding of self/other-in-matrix is central to political and ecological imaginations that are decentered from ethnic, species, class, gender, or other forms of domination and solipsism.John Dewey's work as a whole is a powerful call for such a non-dualistic understanding of individual-in-matrix, and few have better understood its connections to democracy. But, it is in his philosophy of art that Dewey describes most specifically the central importance of the aesthetic dimension of public culture to overcoming crippling dualisms of Western modernity that vitiate participatory engagement- individual/world, nature/culture, ends/means, leisure/work, art/science, aesthetic/ordinary. His writings on art have not been much utilized in the philosophical work for civic environmentalism. This paper argues for their relevance to its key goal of overcoming the segmentation of life ushered in by modernity and buttressed by these dualisms.We first give an overview of recent theories of civic environmentalism and the crises it engages of inequality, injustice, technocracy, corporatization, and the pervasive assault on place and thinning of public participation. Second, we look at the implications of Dewey'saesthetic ecology for an "environmentalism of daily life" that challenges the false dualisms of neo-liberalism and of technocratic professionalism that undermine place-based [End Page 75] forms of life and knowledge. Third, we draw on Dewey's aesthetic philosophy to suggest ways to rebuild democratic public space at the nexus of body, place, and commons. Finally, we briefly outline key philosophical questions that have emerged in our ethnographic and political study of Appalachian grassroots activisms, and that embody this sort of placed, democratic mobilization to protect the civic and environmental commons.

Medea killed her children to take away the smile from her husband's face, according to Euripides, an offence against nature and morality. What if Medea had still been carrying her two children, perhaps due to give birth within a week or so, and had done the same? If this would also have been morally reprehensible, would that be a judgment based on her motives or on her action? We argue that the act has multiple and holistic moral features and that, (...) in fact, there is no absolute principle, such as the right of the fetus to life, which governs our moral judgments about fetal-maternal conflicts. We suggest that they illustrate a pervasive feature of human moral discourse and can only be addressed by attending to a range of negotiable moral considerations which depend on particular features of each situation.

BackgroundIn the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort, participants underwent magnetic resonance imaging (MRI) of the brain, heart, and abdomen, that generated incidental findings (IFs). The approach to managing these unexpected results remain a complex issue. Our objectives were to describe the CAHHM policy for the management of IFs, to understand the impact of disclosing IFs to healthy research participants, and to reflect on the ethical obligations of researchers in future MRI studies.MethodsBetween 2013 and 2019, 8252 participants (...) (mean age 58 ± 9 years, 54% women) were recruited with a follow-up questionnaire administered to 909 participants (40% response rate) at 1-year. The CAHHM policy followed a restricted approach, whereby routine feedback on IFs was not provided. Only IFs of severe structural abnormalities were reported.ResultsSevere structural abnormalities occurred in 8.3% (95% confidence interval 7.7–8.9%) of participants, with the highest proportions found in the brain (4.2%) and abdomen (3.1%). The majority of participants (97%) informed of an IF reported no change in quality of life, with 3% of participants reporting that the knowledge of an IF negatively impacted their quality of life. Furthermore, 50% reported increased stress in learning about an IF, and in 95%, the discovery of an IF did not adversely impact his/her life insurance policy. Most participants (90%) would enrol in the study again and perceived the MRI scan to be beneficial, regardless of whether they were informed of IFs. While the implications of a restricted approach to IF management was perceived to be mostly positive, a degree of diagnostic misconception was present amongst participants, indicating the importance of a more thorough consent process to support participant autonomy.ConclusionThe management of IFs from research MRI scans remain a challenging issue, as participants may experience stress and a reduced quality of life when IFs are disclosed. The restricted approach to IF management in CAHHM demonstrated a fair fulfillment of the overarching ethical principles of respect for autonomy, concern for wellbeing, and justice. The approach outlined in the CAHHM policy may serve as a framework for future research studies.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/nct02220582. (shrink)

The ability to extrapolate essential gist through the analysis and synthesis of information, prediction of potential outcomes, abstraction of ideas, and integration of relationships with world knowledge is critical for higher-order learning. The present study investigated the efficacy of cognitive training to elicit improvements in gist-reasoning and fact recall ability in 556 public middle-school students (grades seven and eight), versus a sample of 357 middle school students who served as a comparison group, to determine if changes in gist-reasoning and fact (...) recall were demonstrated without cognitive training. The results showed that, in general, cognitive training increased gist-reasoning and fact recall abilities in students from families in poverty as well as students from families living above poverty. However, the magnitude of gains in gist-reasoning varied as a function of gender and grade-level. Our primary findings were that seventh and eighth grade girls and eighth grade boys showed significant increases in gist-reasoning after training regardless of socioeconomic status. There were no significant increases in gist-reasoning or fact recall ability for the 357 middle school students who served in the comparison group. We postulate that cognitive training in middle school is efficacious for improving gist-reasoning ability and fact recall in students from all socioeconomic levels. (shrink)

The contributors to this volume address global, regional, and local landscapes, cosmopolitan and indigenous cultures, and human and more-than-human ecology as they work to reveal place-specific tensional dynamics. This unusual book, which covers a wide-ranging array of topics, coheres into a work that will be a valuable reference for scholars of geography and the philosophy of place.

Berkeley's "new theory of vision" and, In particular, His sensationalist solution to the problem of judging distance and magnitude were discussed by many eighteenth-Century authors who faced a variety of problem situations. More specifically, Berkeley's theory fed into the debate over whether the phenomena of vision were susceptible to mathematical analysis or were experientially determined. In this paper a variety of responses to berkeley are examined, Concluding with thomas reid's attempt to distinguish physical optics (which can be analyzed geometrically) (...) from the psychology of vision (in which experience plays a major role).

The view that dominated the last century claims that ethical thought requires thinking of some things – e.g. pleasure, knowledge, virtue – as good “full stop,” or good simpliciter . Traditional Consequentialists, for instance, argue that moral evaluations of acts, motives, etc . are grounded in facts about the simple goodness of that which those things bring about. Similarly, some rational intuitionists think that claims about what one has reason to do are grounded in facts about what is good simpliciter (...) . Such a view gives rise to a set of semantic, metaphysical, and epistemological puzzles about the nature of good simpliciter . I argue that an Aristotelian approach to ethics reveals that ethical thought does not requires good simpliciter , that Aristotelian positions avoid charges of metaphysical and epistemological queerness, and that it gives a straightforward semantic analysis of key moral terms, e.g. morally good/bad and morally right/wrong. I then distinguish between two varieties of Aristotelianism. (shrink)

Michael Williams believes that scepticism about the externalworld seems compelling only because the considerations that underpin it are thoughtto be ``mere platitudes'' about e.g., the nature and source of human knowledge, and hence,that if it shown through a ``theoretical diagnosis'' that it does not rest upon suchplatitudes, but contentious theoretical considerations that we are no means bound toaccept, we can simply dismiss the absurd sceptical conclusion. Williams argues thatscepticism does presuppose two extremely contentious doctrines, however, he admits thatif these doctrines (...) are themselves motivated by ``platitudes'' then scepticism follows. Iaddress Williams's arguments for thinking scepticism must presuppose these doctrines,and argue that he overlooks a way that they can be seen as motivated by mere platitudes.Thus, I conclude that William's novel rejection of scepticism fails.

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.
