The presence of parasites in a population has an impact on mate choice and has substantial evolutionary significance. A relatively unexplored aspect of this dynamic is whether or not the presence of parasites increases the likelihood of hybridization events, which also have a significant role in ecological adaptation. One explanation of increased hybridization in some areas and not others is that stress from parasites results in selection for an increase of novel genotypes. Two swordtail species Xiphophorus birchmanni and Xiphophorus malinche (...) maintain an active hybrid zone. The patterns of hybridization are unique in that they do not match up directly with expectations. We set out to test whether or not individuals can sense, using chemical cues, whether conspecifics in their immediate vicinity have high parasite loads and also whether this has an effect on mating and association behavior toward both conspecific and hybrid mates. Our hypothesis being that females will have greater association times with hybrid/heterospecific mates if conscpecifics are heavily parasitized. We found that females exposed to parasitized males had a weaker preference for conspecific odor than those exposed to unparasitized males, both relative to a water control and relative to hybrids. The empirical investigation described above is coupled with a historical and philosophical discussion of some of the issues surrounding the acceptance and understanding of the concept of hybridization. This discussion takes as its major themes: an analysis of the role that social views have on the formation of scientific hypothesis; the lag between epochal change in the scientific community and the assimilation of the consequences into social beliefs; the survival of hierarchical and teleological thinking in our concept of species and purity; and the failures of contemporary evolutionary theory to provide satisfactory explanations about the meaning and upshot of hybridization. Two specific misconceptions about hybridization are addressed. First, that hybridization clashes with the belief in kinds/types/species having separate and pure identities. Secondly, the teleological view that reads purpose into nature and places all instances of variation on a hierarchical scale; the top and bottom of which are determined by estimated closeness to the predetermined perfection of a type. < <.

I cannot here withhold the statement that optimism, where it is not merely the thoughtless talk of those who harbor nothing but words under their shallow foreheads, seems to me to be not merely an absurd, but also a really wicked, way of thinking, a bitter mockery of the unspeakable sufferings of mankind.1I am now, and always shall be, in that very sense no optimist, but a maintainer of the sterner view that life is forever tragic. In so far as (...) Schopenhauer has sought to make this plain, I follow him unhesitatingly, and honor him for his mercilessness.2Josiah Royce’s lifelong battle with the pessimism of Arthur Schopenhauer supplies valuable insight into the development of one of the central concepts of his system...

This dissertation is centered on problems within the history and philosophy of biology. The project identifies the philosophical roots of the current ecological movement and shows how a version of philosophical naturalism might be put to use within contemporary ethical issues in biology, and aid in the development of research programs. The approach is historically informed, but has application for current dilemmas. The traditions from which I primarily draw include classical American philosophy, particularly C.S. Peirce and John Dewey, as well (...) as thinkers associated with the German Naturphilosophie movement, such as Goethe and Schopenhauer. There are deep, but often overlooked, resonances between these seemingly disparate traditions and contemporary biology that are located in the conflict between the developing organism and the ever-fluctuating environment. The dissertation makes the case for a shared description of nature among these traditions and proposes applications to burgeoning contemporary ecological interpretations of issues such as hybridization and epigenetics.

John Dewey provides a philosophy of nature riven with questions of contexted-function, education, ecological balance, and in general an analysis of nature that understands that fixity won’t work, in the pragmatist sense of work, and consequently, that survival necessitates change. In light of the recent flood of evidence showing that epigenetic factors may have a greater role in evolution than previously thought, a re-envisioning of Dewey’s philosophy of nature is warranted. Dewey’s emphasis on the process of the moving parts, rather (...) than the identity of the parts themselves, provides a contrasting view that largely avoids many of the problems of a gene-centric viewpoint and offers an interpretation of Darwin’s evolutionary theory that emphasizes the instrumental factor of experience in a way that is compatible with the findings of epigenetics.

This volume focuses on the development of empiricism as an interest in the body - as both the object of research and the subject of experience.

In the 18th century, the pre-modern Judeo-Greco-Christian problem of freedom and determinism is transformed by Kant into the modern problem of the freedom of human agency in the natural and cultural worlds of deterministic structures; it is this version of the freedom and determinism issue which centres the Science and Humanism debates, and thus marks the history of the social sciences. Anthony Giddens is credited with providing the new vocabulary of ‘structure’ and ‘agency’ in order to formulate the problem of (...) freedom and determinism in those terms, thus making this formulation fruitful. In this book, Charles R. Varela proposes that Kant originally formulated this problem, and makes a series of wide-ranging and groundbreaking observations based on Kant's metaphysics of realism which enables Varela to propose a solution to the structure/agency problem. Subjects revisited in this book include: · "Giddens’ Call" · The stalemate of the social and psychological sciences · The determinist tradition of modern science · Postmodernism This breadth of themes, drawn together by Varela with his work on Kant, fully realizes Giddens’ principle that human agency is a real causal force. It is Kant's conception of causal power that is the causal force Giddens' has called for. _Science For Humanism: The Recovery of Human Agency_ will be of particular interest to students of humanism and therefore realism, Kant and Giddens.

Let us now consider the third class of statements, those completely nonrestrictive. For example, "Something exists." Since this is the pure contradictory of the wholly restrictive, "Nothing exists," which we have found reason to regard as impossible, and since the contradictory of an impossible statement is necessary, we should expect "Something exists" to be necessarily true, a statement valid a priori. And we see that it excludes nothing from existence, except bare "nothing" itself. But the existence of bare nothing is (...) no existence. Further, "Something exists" is in no conceivable circumstances falsifiable, since the falsifying experience would have to exist, and it would also have to be the experience of something existing--at least if, as I should maintain, experience is essentially a relative term, requiring that to which it is relative, or of which it is the experience. But though "Something exists" is unfalsifiable, it is verified every moment. Could the verifiable but in any conceivable world absolutely unfalsifiable be false? I hold that the necessarily true must be knowable as true and only as true, and that, conversely, whatever is in principle verifiable though not falsifiable is thereby shown to be necessarily true.

The concept of “progress” in evolutionary theory and its relationship to a putative notion of “Progress” in a global, normatively loaded sense of “change for the better” have been the subject of debate since Darwin admonished himself in a marginal note to avoid using the terms ‘higher’ and ‘lower.’ While an increase in some kind of complexity in the natural world might seem self-evident, efforts to explicate this trend meet notorious philosophical difficulties. Numerous historians pin the Modern Synthesis as a (...) pivotal moment in this history; Michael Ruse even provocatively hypothesizes that Ernst Mayr and other “architects” of the Synthesis worked actively to eliminate Progress from evolutionary biology’s scientific purview. I evaluate these claims here with a textual analysis of the journals _Evolution_ and _Proceedings of the Royal Society B_ (a corpus of 27,762 documents), using a dynamic topic modeling approach to track the fate of the term ‘progress’ across the Modern Synthesis. The claim that this term declines in importance for evolutionary theorizing over this period can, indeed, be supported; more tentative evidence is also provided that the discussion of ‘progress’ is largely absent from the British context, emphasizing the role of American paleontology in the rise and fall of ‘progress’ in 20th-century evolutionary biology.

In lieu of an abstract, here is a brief excerpt of the content:Mechanisms of Violent Retribution in Chinese Hell Narratives Charles D. Orzech University ofNorth Carolina Greensboro Ai! The criminals in this hell have all had their eyes dug out and the fresh blood flows [from them], and each of them cries out, their two hands pressing their bloody eye-sockets—truly pitiful! To the left a middle-aged person is just having an eye pulled out by one of the shades; he (...) struggles unceasingly, screaming; his left eye has already been extracted... (56b) Ai-yah!... Each of the criminals is bound to a an iron pillar and the ox-headed demons are in the process of administering punishment—using iron or copper blades they peel the skin of the person's face, just as a butcher kills a pig and then flays it. Each of the criminal ghosts screams in pain... (59b) The criminal ghost's hands are bound about an iron pillar which is entirely red [with heat] and the criminal ghost's two hands are entirely cooked and it is unbearable... (126a) Record ofA Journey to Hell These passages are found, not in some medieval description of hell, nor in a work for sadists, but in a modern and quite popular Chinese "good book" (shan-shu) titled Record ofA Journey to Hell (Ti-yu yu-chi). Record ofA Journey to Hell is the most recent work of a genre which emerged in tenthcentury China and which may be found throughout Asia from Vietnam to Japan. This persistent fascination with gruesome scenes of torture stands in striking contrast to Michel Foucault's observations that by the first quarter of the nineteenth century "punishment had gradually ceased to be a spectacle" in Europe (9). In Record ofA Journey to Hell we are not faced with a seachange in the discourse and practice of a society. Rather, we must come to 112Charles D. Orzech grips with and seek to understand the persistence of images oftorture as well as actual torture and public execution in some modern Chinese societies. The Chinese hells—more properly purgatories, as punishment there is not eternal—are a product of cultural adaptation and interaction. Before the first century of our era we have evidence of only the most attenuated notions of the underworld, a "yellow springs" (huang-yiian) where "all, good and bad, huddled together in darkness being guarded jealously by the god of the Soil who ended by devouring them" (Thompson 29). The ruling elite avoided this fate through elaborate ancestral ritual indexed by the possession of a surname. Social status was, from the earliest times, "inscribed" on tablets which gave visible form to both social and cosmological hierarchies (Li 247-54). However, the rise of the Taoist Celestial Masters movement (T'ien-shih tao, second century) with its heavenly and infernal bureaucracies soon coupled with newly imported Indian Buddhist descriptions of the workings of karma and the hells. The result of this amalgam is the popular Chinese vision of the underworld as a vast bureaucracy centered on ten "courts," and headed by Yama, the South Asian lord of the dead (Seidel). At death the soul is summoned before the lords of hell who administer punishments appropriate to the misdeeds of the soul. After almost interminable periods of suffering, often in all of the hells in succession, the soul is reborn as a human, an animal, or even an insect, to start the whole process again. By the tenth century this distinctly Chinese version ofthe underworld had found wide dissemination and was the framework for worship and ritual directed to the recently dead.18 Unlike the South Asian prototypes, Chinese hells appear to be modeled on the imperial bureaucracy and administered by a hellish staff. The "court" layout often major and numerous subsidiary hells mimics Chinese palace and temple architecture and is quite distinct from the mandala-like layout found in "orthodox" Buddhist prototypes. Taoist priests, Buddhist monks and nuns, and a variety of folk practitioners and mediums act as intermediaries between this world and the other. They grease the wheels of the bureaucracy with their ritual knowledge and with community offerings to obtain release for imprisoned souls. Knowledge of the workings of the underworld is, according...

Research in the intensive care unit (ICU) is commonly thought to pose 'serious risk' to study participants. This perception may be at the root of a variety of impediments to the conduct of clinical trials in the ICU setting. Component analysis offers a promising approach to the ethical analysis of ICU research. Because clinical trials commonly involve a mixture of study interventions, therapeutic and nontherapeutic procedures must be analyzed separately. Therapeutic procedures must meet the requirement of clinical equipoise. Risks associated (...) with nontherapeutic procedures must be minimized consistent with sound scientific design, and be deemed reasonable in relation to the knowledge to be gained. When research involves a vulnerable population, such as adults incapable of providing informed consent, nontherapeutic risks are limited to a minor increase over minimal risk. Understood in this way, the incremental risk posed by participation in ICU research may be minimal. This realization has important implications for review by institutional review boards of such research and for the informed consent process. (shrink)

This is a book about hope in the midst of a polarized culture. Camosy begins with a hopeful starting point in the midst of a crumbling US political culture: two of every three Americans constitute an exhausted majority who reject right/left polarization and are open to alternative viewpoints. Especially at this time of realignment, we have been given a unique moment to put aside the frothy, angsty political debates and think harder about our deepest values. A Consistent Life Ethic, especially (...) one which embraces Pope Francis' challenge to resist throwaway culture, has the capacity to unite people who for the last several decades imagined themselves in a polarized culture war. On issues ranging from hook-up culture, reproductive technology, abortion, euthanasia, poverty, immigration, treatment of animals, and mass incarceration, this book articulates a new moral vision in which a culture of encounter and hospitality replaces a consumer culture in which the most vulnerable get used and discarded as so much trash. At bottom, Camosy offers readers a golden opportunity to dialogue about what kinds of values should serve as the foundation for a new political culture. (shrink)

Originally published in 1910, this is a volume of philosophy by an author who found his main calling in the creation of novels, Charles Francis Keary. Unusual in its relatively personal exploration of ideas, together with its accessible, literary style, the text nonetheless maintains an academically rigorous approach to its exploration of the boundaries of reason. The fundamental premise is that mental processes generally thought to be based on intuition can, more accurately, be seen to find their basis in (...) reasoning; this premise, in turn, forms the basis for an exposition of Keary's philosophy of life and religion. This is a highly readable, and critically underrated, book that will be of value to anyone with an interest in philosophy and theology. (shrink)

ABSTRACT In this article we call for a paradigm change in relation to the way we tend to look at how markets and morals are entwined in the writings of Jonathan Swift (1667–1745). We argue that it would be wrong to apply contemporary notions of economics retrospectively and somewhat a-historically to a thinker of an axial time in which economics as a separate sphere did not exist, and morals and markets and the way they relate to each other were about (...) to be reconceptualised. We argue that it is thus no accident that Scottish Enlightenment thinkers such as David Hume and Adam Smith took to Swift. They admired more than the expressive or rhetorical skills in Swift; in the first instance, they read Swift as somebody who managed to express moral sentiments (and even outrage) in an appealing, that is mostly satirical way, thereby not only criticizing the cruel conditions in Ireland at the time but also identifying the gap between rhetoric and reality and thus taking issue with the hypocrisy and double standards of the time. We will use two famous examples of Swift's work to illustrate our case, A Modest Proposal (1729) and Directions to Servants (1745). (shrink)

Originally published in 1963, this classic book is a rethinking of the history of Western political philosophy. Charles N. R. McCoy contrasts classical-medieval principles against the "hypotheses" at the root of modern liberalism and modern conservativism. In Part I, "The Classical Christian Tradition from Plato to Aquinas," the author lays the foundation for a philosophical "structure" capable of producing "constitutional liberty." Part II, "The Modern Theory of Politics from Machiavelli to Marx," attempts to show, beginning with Machiavelli, the reversal (...) and destruction of the pre-modern "structure" postulated in Part I. McCoy stresses the great contributions of Aristotle to political thought found in his more familiar Ethics and Politics, but also includes key insights drawn from Metaphysics and Physics. These contributions are developed and perfected, McCoy argues, by Augustine and Aquinas. Two other important features include McCoy's epistemological insights into Plato's work that will be new to many readers and the author's juxtaposition of traditional natural law with "the modernized theory of natural law." The modern account of autonomous natural law, in McCoy's view, helps explain the totalitarian direction of key aspects of modern political thought. This classic volume on the origins of modern philosophical thought remains a standard in the field. (shrink)

" Nous avons en nous un principe divin, et c'est ce principe qui constitue essentiellement l'homme. N'écoutons donc pas ceux qui veulent que l'homme ne vive que pour les choses mortelles. Nous devons, au contraire, vivre par ce qu'il y a de sublime en nous, par le principe divin qui fait notre grandeur et notre dignité.

C'est au contraire une véritable histoire qui se déroule sous nos yeux, celle d'une pensée vivante émergeant peu à peu des cosmogonies primitives, et aboutissant aux spéculations complexes et raffinées de Platon et Aristote, pour fléchir ensuite et se relever une dernière fois avec Plotin.

Well prior to the invention of the term ‘biology’ in the early 1800s by Lamarck and Treviranus (and lesser-known figures in the decades prior), and also prior to the appearance of terms such as ‘organism’ under the pen of Leibniz and Stahl in the early 1700s, the question of ‘Life’, that is, the status of living organisms within the broader physico-mechanical universe, agitated different corners of the European intellectual scene. From modern Epicureanism to medical Newtonianism, from Stahlian animism to the (...) discourse on the ‘animal economy’ in vitalist medicine, models of living being were constructed in opposition to ‘merely anatomical’, structural, mechanical models. It is therefore striking that the classic narratives of the Scientific Revolution conspicuously avoid any consideration of what status to grant living beings in a newly physicalized universe (I discuss this in Wolfe 2011, 2019 chapt. 1). Neither Harvey, nor Boyle, nor Locke (to name some likely candidates, the latter having studied with Willis and collaborated with Sydenham) ever ask what makes organisms unique, or conversely, what does not. In this chapter I seek to establish how something we might call ‘the knowledge of Life’, to use an expression of Georges Canguilhem’s, emerged as part of early modernity without being part of the mainstream history of life science. This leads to the question, can one can correlate early modern “knowledge of life” with the emergence of a science called ‘biology’? (see Zammito 2018, Wolfe 2019, Bognon-Küss and Wolfe eds. 2019). It was once fashionable to speak of, e.g. ‘precursors of Darwin’, and then Canguilhem and Foucault famously did away with the category of precursor. But how then do we account for the phase that precedes the constitution of a science? With the case of biology, how do we account for the increasing fascination with the ontology of Life during the decades prior to the ‘naming of biology’, as McLaughlin has called it, at the end of the eighteenth century? This increased focus on Life and the ontology of Life sits awkwardly, both with mainstream narratives of the Scientific Revolution and of the history of biology. In seeking to address this increased focus (in which vitalism plays a role but was by no means the only conceptual actor: Wolfe 2020), I critically examine Foucault’s notorious claim (Foucault 1966) that there was no such thing as ‘Life’ in the eighteenth century and thus no such thing as biology.

It is the purpose of this paper to review the present status of discussion concerning the concept of probability. The exposition will consist of six sections: A brief statement of the most important traditional views of the concept of probability: subjective and objective; A brief criticism of two traditionally important conceptions: a priori probability and the Principle of Indifference; A criticism of an outstanding example of the subjective theory of probability, the theory of F. P. Ramsey; A criticism of the (...) most widely known of the objective logical theories of probability, the theory of J. M. Keynes; Some remarks concerning the results of the recent work of Reichenbach and von Mises with particular reference to clarification of the concept of probability; A summary of the case for the frequency interpretation of probability, revealing its basic importance in the light of present evidence.
