Luck permeates our lives, and this raises a number of pressing questions: What is luck? When we attribute luck to people, circumstances, or events, what are we attributing? Do we have any obligations to mitigate the harms done to people who are less fortunate? And to what extent is deserving praise or blame a ected by good or bad luck? Although acquiring a true belief by an uneducated guess involves a kind of luck that precludes knowledge, does all luck undermine (...) knowledge? And how accurate are our luck attributions anyway? The academic literature has seen growing, interdisciplinary interest in luck, and this volume brings together and explains the most important areas of this research. It consists of 39 newly commissioned chapters, written by an internationally acclaimed team of philosophers and psychologists, for a readership of students and researchers. Its coverage is divided into six sections: (i) The History of Luck, (ii) The Nature of Luck, (iii) Moral Luck, (iv) Epistemic Luck, (v) The Psychology of Luck, and (vi) Future Research. The chapters in these sections cover a wide range of topics, from the problem of moral luck, to anti-luck epistemology, to the relationship between luck attributions and cognitive biases, to meta-questions regarding the nature of luck itself, to a range of other theoretical and empirical questions currently being investigated by ethicists, epistemologists, and psychologists. By bringing this research together, the Handbook serves as both a touchstone for understanding the relevant issues and a first port of call for future philosophical and psychological research on luck.

The relationship between construal and redundancy has not been previously explored empirically. Russian aspect allows speakers to construe situations as either Perfective or Imperfective, but it is not clear to what extent aspect is determined by context and therefore redundant. We investigate the relationship between redundancy and open construal by surveying 501 native Russian speakers who rated the acceptability of both Perfective and Imperfective verb forms in complete extensive authentic contexts. We find that aspect is largely redundant in 81% of (...) uses, and in 17% of contexts aspect is relatively open to construal. We contend that anchoring in redundant contexts likely facilitates the independence of construal in contexts with less redundancy. However further research is needed to discover what makes contexts redundant since known cues for aspect are absent in the majority of such contexts. Native speakers are fairly consistent in giving the original aspect high ratings, but less consistent in rating the non-original aspect, indicating potential problems in testing the reactions of speakers to non-authentic data.

Postural instability in Parkinson’s disease (PD) is characterized by impaired postural responses to transient perturbations, increased postural sway in stance and difficulty transitioning between tasks. In addition, some studies suggest that loss of dopamine in the basal ganglia due to PD results in difficulty using proprioceptive information for motor control. Here, we quantify the ability of subjects with PD and age-matched control subjects to use and re-weight sensory information for postural control during steady-state conditions of continuous rotations of the stance (...) surface or visual surround. We measure the postural sway of subjects in response to a pseudorandom, surface-tilt stimulus with eyes closed, and in response to a pseudorandom, visual-tilt stimulus. We use a feedback control model of the postural control system to interpret our results, focusing on sensory weighting as a function of stimulus amplitude. We find that subjects with PD can re-weight their dependence upon sensory information in response to changes in surface- or visual-stimulus amplitude. Specifically, subjects with PD behaved like age-matched control subjects by decreasing proprioceptive contribution to stance control with increasing surface-tilt amplitude, and decreasing visual contribution with increasing visual-tilt amplitude. However, subjects with PD do not decrease their reliance on proprioception as much as age-matched controls for small increases in surface-stimulus amplitudes. Levodopa medication did not affect sensory re-weighting behaviors for postural control. The impairment in PD subject’s ability to respond differently to small changes in surface rotation amplitudes is consistent with an increased threshold for perceiving proprioceptive signals, which may result from decreased signal-to-noise in the dopaminergic pathways associated with sensory processing and/or sensory integration.

The Phenomenon of Man, by Pierre Teilhard de Chardin, has been characterized as metaphysics, poetry, and mysticism-virtually everything except what its author claimed it was: a "purely scientific mémoir." Professor O'Connell here follows up on a nest of clues, uncovered first in an early unpublished essay, then in the series of essays contained principally in The Vision of the Past. Those clues all point to Teilhard's intimate familiarity with the philosophy of science propounded by the celebrated Pierre Duhem. It was (...) Duhem's central claim that science, to remain true to itself, must aim at establishing a genuine "natural classification" phenomenal reality. That insight, Professor O'Connell argues, guided Teilhard's lifelong effort to describe the "imposed reality-factors" which science in its variety of forms suggests as ingredients and operative at every phase in the evolutionary development of planet Earth. Limiting his focus to the way Teilhard unfolded his vision of the past, Professor O'Connell concludes that those who deprecate Teilhard as unscientific betray little awareness of how sophisticated his understanding of science truly was.

In Darwinian Heresies, which was originally published in 2004, prominent historians and philosophers of science trace the history of evolutionary thought, and challenge many of the assumptions that have built up over the years. Covering a wide range of issues starting in the eighteenth century, Darwinian Heresies brings us through the time of Charles Darwin and the Origin, and then through the twentieth century to the present. It is suggested that Darwin's true roots lie in Germany, not his native England, (...) that Russian evolutionism is more significant than many are prepared to allow, and that the true influence on twentieth-century evolution biology was not Charles Darwin at all, but his often-despised contemporary, Herbert Spencer. The collection was intended to interest, to excite, to infuriate, and to stimulate further work. (shrink)

Classifications of animals and plants have long been represented by hierarchical lists of taxa, but occasional authors have drawn diagrammatic versions of their classifications in an attempt to better depict the "natural relationships" of their organisms. Ornithologists in 19th-century Britain produced and pioneered many types of classificatory diagrams, and these fall into three groups: (a) the quinarian systems of Vigors and Swainson (1820s and 1830s); (b) the "maps" of Strickland and Wallace (1840s and 1850s); and (c) the evolutionary diagrams of (...) the post-Darwin authors (1860 on). The quinarians distinguished between affinity and analogy and used both in their classifications, whereas Strickland rejected the quinarians' belief in numerical regularity and their use of analogy. Wallace's "maps" are easily given an evolutionary interpretation, and his approach was taken up and modified by later evolutionary anatomists. Sharpe returned to Strickland's methods and merely appended a superficial evolutionary interpretation. Contrary to common belief systematics has a rich conceptual history, and many of the conceptual developments in 19th-century systematics were made by ornithologists. (shrink)

This book rounds off the study of St. Augustine's view of the human condition which Fr. O'Connell began in St. Augustine's Early Theory of Man, A.D. 386-391, and continued in St. Augustine's Confessions: The Odyssey of Soul. The central thesis of that first book, and the guiding hypothesis of the second, proposed that Augustine thought of us in "Plotinian" terms, as "fallen souls," and that he interpreted, in all sincerity, the teachings of Scripture as reflecting that same view. O'Connell sees (...) the weightiest objection to his proposal as stemming from what scholars generally agree is Augustine's firm rejection of that view in his later works. The central contention here is that Augustine did indeed reject his earlier theory, but only for a short while. He came to see the text from Romans 9, 11 as apparently compelling that rejection. But then his firm belief that all humans are guilty of original sin would have left him traducianism as his only acceptable way of understanding the origin of sinful human souls. The materialistic cast of traducianism, however, always repelled Augustine. Hence, he struggles to elaborate a fresh interpretation of Romans 9,11, and eventually he finds one that permits him to return to a slightly revised version of his earlier view. That theory, O'Connell argues, is encased in both the De Civitate Dei and the final version of the De Trinitate. This terse summary barely hints at the richness of detail contained here: O'Connell beginswith a minute analysis of the third book of the De Libero Arbitrio, then of the letters and works ostensibly supporting rival chronological patterns which he must overturn in order to make his case. Finally, in the light of his findings, he offers fresh interpretations of Augustine's three mature masterpieces, On Genesis, The Trinity, and City of god. These, along with Fr. O'Connell's contention that Augustine's anti-Pelagian De Peccatorum Meritis et Remissione must have seen publication no earlier than A.D. 416/17, will doubtless fuel scholarly debate for some time to come. Indeed, Pelagianism made the question of the soul's origin so pivotal for Augustine, that few of our current interpretations of Augustine are likely to remain unaffected by the results of O'Connell's searching and provocative study.

Retroviruses are unusual amongst animal viruses in their capacity to integrate into host genomes and be transmitted vertically to host progeny. Vertebrate genomes contain numerous and diverse retrovirus‐derived sequences reflecting a long co‐evolutionary history during which genome invasion has occurred repeatedly, with wide‐ranging evolutionary consequences. Over the past 10 years, a detailed picture of retroviral diversity throughout vertebrate genomes has emerged, revealing striking and informative patterns that differ markedly across species. The power of these data to deliver far‐reaching insights into (...) the biology and evolution of retroviruses has been significantly advanced by recent studies identifying ongoing genome invasion in wild populations,(1) and by the characterisation of conserved mechanisms of innate antiretroviral defence.(2,3) BioEssays 28: 1153–1156, 2006. © 2006 Wiley Periodicals, Inc.

This volume traces the influence of the British Empiricists--John Locke and David Hume--upon the American pragmatists--Charles S Peirce, William James, and John Dewey. But there are significant differences between the two traditions so that it can be said that the pragmatists gave the classical empirical tradition new directions. Heretofore these lines of influence and divergence have been recognized but not sufficiently developed. This movement is illustrated in chapters on experience, necessary connection, personal identity, and moral, social, and political theory. A (...) final chapter indicates the challenges that are still to be addressed by pragmatism. (shrink)

138 titles across a wide range of scholarly publications illustrate the conceptual affinities that connect the palaetiological sciences of biological systematics, historical linguistics, and stemmatics. These three fields all have as their central objective the reconstruction of evolutionary "trees of history" that depict phylogenetic patterns of descent with modification among species, languages, and manuscripts. All three fields flourished in the nineteenth century, underwent parallel periods of quiescence in the early twentieth century, and in recent decades have seen widespread parallel revivals. (...) "Tree thinking" (O'Hara, 1988) is now standard within evolutionary biology, and the unity of what William Whewell called palaetiology is being once again appreciated by scholars and scientists in many fields.

Grants flexibility to instructors by (...) offering a wide variety of selections (more than 80) to choose from depending upon the focus of their courses. (shrink)

We discuss two kinds of quotation, namely indirect quotation and pure quotation. With respect to each, we have both a negative and a positive plaint. The negative plaint is that the strict Davidsonian treatment of indirect and pure quotation cannot be correct. The positive plaint is an alternative account of how quotation of these two sorts works. /// Discutimos dos tipos de citas, a saber, citas indirectas y citas puras. Hacemos dos planteamientos, uno positivo y otro negativo, con respecto a (...) cada una. El negativo es que el tratamiento estrictamente davidsoniano de las citas indirectas y puras no puede ser correcto. El positivo consiste en dar una explicatión alternativa de cómo funcionan estos dos tipos de citas. (shrink)
