Darcy's law is a phenomenological relationship for fluid flow rate that finds one of its principle applications in hydrology. Theoretical hydrologists rely upon a multiplicity of conceptual models to carry out approximate derivations of Darcy's law. These derivations provide structural explanations of the law; they require the application of fundamental principles, such as conservation of momentum, to idealized models of the porous media within which the flow occurs. In practice, recognition of the idealized conditions incorporated into models facilitates the empirical (...) clarification of the domain within which the law remains accurate. Structural explanations also contribute to the physical interpretation of phenomenological parameters. (shrink)

Building upon Nancy Cartwright's discussion of models in How the Laws of Physics Lie, this paper addresses solid state research in transition metal oxides. Historical analysis reveals that in this domain models function both as the culmination of phenomenology and the commencement of theoretical explanation. Those solid state chemists who concentrate on the description of phenomena pertinent to specific elements or compounds assess models according to different standards than those who seek explanation grounded in approximate applications of the Schroedinger equation. (...) Accurate accounts of scientific debate in this field must include both perspectives. (shrink)

Creationists who object to evolution in the science curriculum of public schools often cite Jonathan Well’s book Icons of Evolution in their support (Wells 2000). In the third chapter of his book Wells claims that neither paleontological nor molecular evidence supports the thesis that the history of life is an evolutionary process of descent from preexisting ancestors. We argue that Wells inappropriately relies upon ambiguities inherent in the term ‘Darwinian’ and the phrase ‘Darwin’s theory’. Furthermore, he does not accurately distinguish (...) between the overwhelming evidence that supports the thesis of common descent and controversies that pertain to causal mechanisms such as natural selection. We also argue that Wells’ attempts to undermine the evidence in support of common descent are flawed and his characterization of the relevant data is misleading. In particular, his assessment of the ‘Cambrian explosion’ does not do justice to the fossil record. Nor do his selective references to debate about molecular and paleontological phylogenies constitute a case against common descent. We conclude that the fossil and molecular evidence is more than sufficient to warrant science educators to present common descent as a well-established scientific fact. We also argue that diagrams depicting the ‘tree of life’ can be pedagogically useful as simplified representations of the history of life. (shrink)

As documented in Part I, monogenism, the descent of all human beings from Adam and Eve, was closely linked to the Catholic doctrine of original sin throughout the first half of the twentieth century. Theological reservations about polygenism, the more scientifically supported account of human origins through a transitional population, was brought to a head by Pius XII’s 1950 encyclical Humani generis. Although the encyclical allowed discussion of human evolution, polygenism was prohibited because “It does not appear how such a (...) view can be reconciled with the doctrine of original sin.” Nevertheless, during and after Vatican II de facto theological acceptance of polygenism became commonplace even though the prohibition was not withdrawn. While some modern conceptions of original sin make a reliance upon monogenism unnecessary, another school of thought emphasizes a spiritual rather than a biological understanding of the concept. It remains to be seen whether polygenism can be unanimously accepted as a scientific phenomenon that is not theologically threatening. Reflection on the Vatican’s long period of ambivalence about the motion of the earth suggests that a similar prospect can be foreseen for polygenism even though it is subject to development in a manner that geostasis was not.

Theological attention to the Catholic doctrine of original sin has a history that extends from the letters of Saint Paul through the Council of Trent and Pius XII’s 1950 encyclical, Humani generis. The doctrine has traditionally been articulated through the Genesis narrative of Adam and Eve as the first human beings from whom all others descend, an account known as monogenism. In the course of the nineteenth century, scientific research into human origins increasingly relied upon polygenism, the descent of humanity (...) from non-human ancestors through a transitional population. Subsequent Catholic engagement with evolution included resistance to polygenism from the Vatican due to a perceived conflict with the doctrine of original sin. Humani generis included a prohibition that remains in place today in spite of widespread de facto acceptance of polygenism among theologians. Understanding the origin and persistence of this disparity stands to benefit from comparison to a corresponding ambivalence toward the sixteenth century Copernican hypothesis of a moving earth, only conclusively resolved in 1992. In Part I of this essay I introduce this historical comparison and describe the origins of monogenism and polygenism terminology in nineteenth century debate over the unity of the human race. I then describe the conceptual changes that transpired during the first half of the twentieth century and the resulting role of polygenism in the nouvelle théologie of the decade prior to Humani generis. Subsequent developments and implications follow in Part II. (shrink)

Working within the framework of Thomistic metaphysics, Mariusz Tabaczek O. P. has developed a version of Catholic theistic evolution that includes speciation, human origins, and the origin of life. He assigns biological evolution to the domain of divine governance rather than that of _creatio ex nihilo_ which only applies to primitive matter and human souls. This article reviews Tabaczek’s work with an emphasis on his argument for the compatibility of hylomorphism and evolutionary change through the eduction of novel substantial forms.

Recent work by historians and philosophers has called attention to the complexity of modern experimental physics and its intricate relation to interpretive and explanatory theory (Franklin 1987, Hacking 1983, Galison 1987 and 1989, Pickering 1984 and 1987). One point of general agreement has been that the contexts of discovery and justification often significantly overlap and do not uniformly correlate with experiment and theory. Instead, intended applications, instrumentation, experiment, phenomenological description, explicative models, and explanatory theory all act both as incentives and (...) as constraints during the production of scientific knowledge. The present paper investigates how one node of this network operates in the domain of solid state physics and chemistry. In particular, a case study analysis of how models function in transition metal oxide research provides ample support for several conclusions.First, it must be emphasized that the term “theory” can have misleading connotations in this domain if it is allowed to imply a single and foundational level of explanatory generality.

This essay is a critique of a version of progressive creation developed by Michael Chaberek, O. P. He holds that there are exceptions to evolutionary descent due to the supernatural production of “natural species,” taxa that allegedly do not have biological ancestry, are theologically identified with biblical kinds, and are metaphysically characterized by distinct substantial forms. Chaberek’s assertion that these natural species correspond “roughly” to the Linnaean taxa of biological families contradicts modern scientific conclusions regarding the continuity of evolutionary descent. (...) To illustrate this conflict, I examine some of the extensive evidence for the evolutionary origins of families within the Feliformia sub-order. I conclude that Chaberek’s assertion of supernatural progressive creation is a God-of-the-gaps theology burdened by a defensive stance with respect to scientific progress. (shrink)

The reference of the postmodern task of thinking is Auschwitz, the abyss and discontinuity separating us from the world of our ancestors. As inhabitants of Planet Auschwitz our point of reference lacks all transcendental warrants; it is not a non-referable reference which constitutes the abyss we must enter, endure, and in which our intellectual and cultural tradition must be transformed. The private/public transformations which constitute the texts of this book attempt to depart from the dystopic individuality and public life resulting (...) from business-as-usual after Auschwitz. The three parts of the book are progressive reworkings of traditional metaphysics as adapted and modified by a modernism that refuses to grapple with its complicity. It is precisely that complicity which postmodern thinking takes up in its attempt to signify otherwise than the easy modernist translations and images of tradition. Thus it is a series of uneasy images imaging otherwise but never apart from modernity that take us away from complicity toward a transformed tradition. The uneasy images of this book are photogrammic combinations of photographs and texts, mutual supplements, pulling tradition through the Event against the persistent and murderous forces of contemporary idolatry and repression.

A fresh explication of the Thomist justification of self-defense casts off the hobbles of the principle of double effects to find a more secure footing in the historicaldevelopment of subjective natural rights by medieval jurists, and a straight-forward application to the latent threat of death in childbirth posed by non-consensual pregnancy. By articulating the implicit Thomistic right to defensive abortion in terms of conditional rights bestowed in Creation as correlative to particular natural law duties, justly proportionate limits to defensive abortion (...) are identified, and balanced against the forfeited or reserved natural rights variously imputed to conceptus and embryo in non-consensual pregnancies. Subsequently, the varieties of involuntary consent are examined from a Thomist perspective with a view to their relevance in justifying recourse to a rehabilitated practice of defensive abortion when free and full consent to impregnation and childbirth is absent.

Politics and religion certainly ride together throughout the Dune saga. Rationales were given to support twentieth century dictator ships, whose citizens were encouraged to see their leaders as infallible. In this way, politics in a totalitarian state resembled a religion, with a community of faithful followers and its own special theology to justify the dictator's authority. This chapter, draws parallels between the religious dimensions of politics in Frank Herbert's Dune novels and some philosophers’ views on tyranny and justice here on (...) Earth. Even in democratic countries, leaders still tend to think of themselves as in service to some higher, impersonal standard, like a set of principles, a tradition, a flag, or a constitution. Plato's readers have sometimes described the relation between the higher plane of reality of universals and the world of everyday experience in terms of the relation between heaven and earth in the Abrahamic religions.

Every year in this country, some 10,000 college and university courses are taught in applied ethics. And many professional organizations now have their own codes of ethics. Yet social science has had little impact upon applied ethics. This book promises to change that trend by illustrating how social science can make a contribution to applied ethics. The text reports psychological studies relevant to applied ethics for many professionals, including accountants, college students and teachers, counselors, dentists, doctors, journalists, nurses, school teachers, (...) athletes, and veterinarians. Each chapter begins with the research base of the cognitive-developmental approach--especially linked to Kohlberg and Rest's Defining Issues Test. Finally, the book summarizes recent research on the following issues: * moral judgment scores within and between professions, * pre- and post-test evaluations of ethics education programs, * moral judgment and moral behavior, * models of professional ethicseducation, and * models for developing new assessment tools. Researchers in different professional fields investigate different questions, develop different research strategies, and report different findings. Typically researchers of one professional field are not aware of research in other fields. An important aim of the present book is to bring this diverse research together so that cross-fertilization can occur and ideas from one field can transfer to another. (shrink)

The results of four experiments provide evidence for controlled processing in the absence of awareness. Participants identified the colour of a neutral distracter word. Each of four words was presented in one of the four colours 75% of the time or 50% of the time . Colour identification was faster when the words appeared in the colour they were most often presented in relative to when they appeared in another colour, even for participants who were subjectively unaware of any contingencies (...) between the words and the colours. An analysis of sequence effects showed that participants who were unaware of the relation between distracter words and colours nonetheless controlled the impact of the word on performance depending on the nature of the previous trial. A block analysis of contingency-unaware participants revealed that contingencies were learned rapidly in the first block of trials. Experiment 3 showed that the contingency effect does not depend on the level of awareness, thus ruling out explicit strategy accounts. Finally, Experiment 4 showed that the contingency effect results from behavioural control and not from semantic association or stimulus familiarity. These results thus provide evidence for implicit control. (shrink)

Drawing upon work in evolutionary game theory and experimental philosophy, I argue that one of the roles the concept of knowledge plays in our social cognitive ecology is that of enabling us to make adaptively important distinctions between different kinds of blameworthy and blameless behaviors. In particular, I argue that knowledge enables us to distinguish which agents are most worthy of blame for inflicting harms, violating social norms, or cheating in situations of social exchange.

Recent empirical work on folk moral objectivism has attempted to examine the extent to which folk morality presumes that moral judgments are objectively true or false. Some researchers report findings that they take to indicate folk commitment to objectivism (Goodwin & Darley, 2008, 2010, 2012; Nichols & Folds-Bennett, 2003; Wainryb et al., 2004), while others report findings that may reveal a more variable commitment to objectivism (Beebe, 2014; Beebe et al., 2015; Beebe & Sackris, 2016; Sarkissian, et al., 2011; Wright, (...) 2018; Wright, Grandjean, & McWhite, 2013; Wright, McWhite, & Grandjean, 2014). However, the various probes that have been used to examine folk moral objectivism almost always fail to be good direct measures of objectivism. Some critics (Beebe, 2015; Pölzler, 2017, 2018) have suggested that the problems with existing probes are serious enough that they should be viewed as largely incapable of shedding any light on folk metaethical commitments. Building upon the work of Justin Khoo and Joshua Knobe (2018), I argue that many of the existing probes can be seen as good measures of the extent to which people think that the truth of one moral judgment excludes the possibility that a judgment made by a disagreeing party is also true and that the best explanation of the findings obtained using these measures is significant folk support for indexical moral relativism—the view that the content of moral judgments is context-sensitive. If my thesis is correct, many contemporary moral philosophers are deeply mistaken about the metaethical contours of folk morality in one very important respect. (shrink)

Experimental epistemology uses experimental methods of the cognitive sciences to shed light on debates within epistemology,the philosophical study of knowledge and rationally justified belief. In this first critical collection on this exciting new subfield, leading researchers tackle key questions pertaining to knowledge, evidence, and rationally justified belief.

We report the results of an exploratory study that examines the judgments of climate scientists, climate policy experts, astrophysicists, and non-experts (N = 3367) about the factors that contribute to the creation and persistence of disagreement within climate science and astrophysics and about how one should respond to expert disagreement. We found that, as compared to non-experts, climate experts believe that within climate science (i) there is less disagreement about climate change, (ii) methodological factors play less of a role in (...) generating disagreements, (iii) fewer personal or institutional biases influence climate research, and (iv) there is more agreement about which methods should be used to examine relevant phenomena we also observed that the uniquely American political context predicted experts’ judgments about some of these factors. We also found that, in regard to disagreements concerning cosmic ray physics, and commensurate with the greater inherent uncertainty and data lacunae in their field, astrophysicists working on cosmic rays were generally more willing to acknowledge expert disagreement, more open to the idea that a set of data can have multiple valid interpretations, and generally less quick to dismiss someone articulating a non-standard view as non-expert, than climate scientists were in regard to climate science.

We develop an account of laboratory models, which have been central to the group selection controversy. We compare arguments for group selection in nature with Darwin's arguments for natural selection to argue that laboratory models provide important grounds for causal claims about selection. Biologists get information about causes and cause-effect relationships in the laboratory because of the special role their own causal agency plays there. They can also get information about patterns of effects and antecedent conditions in nature. But to (...) argue that some cause is actually responsible in nature, they require an inference from knowledge of causes in the laboratory context and of effects in the natural context. This process, cause detection, forms the core of an analogical argument for group selection. We discuss the differing roles of mathematical and laboratory models in constructing selective explanations at the group level and apply our discussion to the units of selection controversy to distinguish between the related problems of cause determination and evaluation of evidence. Because laboratory models are at the intersection of the two problems, their study is crucial for framing a coherent theory of explanation for evolutionary biology. (shrink)

We report the results of four empirical studies designed to investigate the extent to which an epistemic closure principle for knowledge is reflected in folk epistemology. Previous work by Turri (2015a) suggested that our shared epistemic practices may only include a source-relative closure principle—one that applies to perceptual beliefs but not to inferential beliefs. We argue that the results of our studies provide reason for thinking that individuals are making a performance error when their knowledge attributions and denials conflict with (...) the closure principle. When we used research materials that overcome what we think are difficulties with Turri’s original materials, we found that participants did not reject closure. Furthermore, when we presented Turri’s original materials to non-philosophers with expertise in deductive reasoning (viz., professional mathematicians), they endorsed closure for both perceptual and inferential beliefs. Our results suggest that an unrestricted closure principle—one that applies to all beliefs, regardless of their source—provides a better model of folk patterns of knowledge attribution than a source-relative closure principle.

Knobe (2003a, 2003b, 2004b) and others have demonstrated the surprising fact that the valence of a side-effect action can affect intuitions about whether that action was performed intentionally. Here we report the results of an experiment that extends these findings by testing for an analogous effect regarding knowledge attributions. Our results suggest that subjects are less likely to find that an agent knows an action will bring about a side-effect when the effect is good than when it is bad. It (...) is further argued that these findings, while preliminary, have important implications for recent debates within epistemology about the relationship between knowledge and action. (shrink)

An overview of the main areas of epistemological debate to which experimental philosophers have been contributing and the larger, philosophical challenges these contributions have raised.

Having asked, “What, then, is time?” Augustine admitted, “I know well enough what it is, provided that nobody asks me; but if I am asked what it is and try to explain, I am baffled.” We all have a sense of time, but the description and explanation of it remain remarkably elusive. Through a series of detailed descriptions, Husserl attempted to clarify this sense of time. In my book, I trace the development of his account of our temporal self-awareness, starting (...) with his early 1905-1909 lectures on time consciousness and proceeding through the 1917-18 Bernau Manuscripts, the Analyses of Passive Syntheses of the 1920’s and ending with the C, B and E manuscripts on time and instincts of the 1930s. Although my book covers all the stages of Husserl’s account of temporality, it is nonetheless systematic in its approach. It is organized about a number of basic topics in the theory of time and presents and critically appraises Husserl’s positions on the issues pertaining to each. • THE ONTOLOGICAL STATUS OF TIME: Is time objective or subjective? Is it “out there,” a part of external reality or does it have a merely subjective existence, residing only in our memories and anticipations? Does Husserl’s “subjective” account presuppose ob-jective time? • THE “PRESENCE” OF THE PAST AS PAST: Memory, if it is to be distinguished from a direct, sensuous perception, must grasp the past as past. It must somehow “see” what no longer exists as no longer existing. The issue is: how do we do this? The same question arises with regard to our grasp through anticipation of the future as future. • THE TEMPORALITY OF OBJECTS: For Husserl, the apprehension of any sort of extended event, such as a melody, involves the synthesis of the “retentions” (the short term memories) of its notes and the anticipations these retentions awake in us. The question, here, is: what exactly is involved in this synthesis of retentions and anticipa-tions? How can these elements come together to present a single, individual object rather than presenting us with merely a collection of disparate presentations? In other words: How does temporal synthesis accomplish this presentation? • THE TEMPORALITY OF CONSCIOUSNESS: Husserl asserts that consciousness, in placing its object in time also places itself in time. How does it do this? What is the relation between the consciousness that places itself in time and the consciousness that is placed in time? How do we unify them? • THE ONTOLOGICAL STATUS OF TIME-CONSTITUTING PHENOMENA: Husserl claims that “time-constituting phenomena are evidently objectivities fundamentally different than those constituted in time. They are neither individual objects nor individual processes, and the predicates of such objects or processes cannot be meaningfully ascribed to them.” This assertion raises a number of questions about the ontological status of these time-constituting phenomena. If we cannot apply the predicates of individual objects to them, what is the nature of their being? Given that such phenomena com-pose the field of consciousness, what is the ontological status of consciousness? Furthermore, if our apprehension directs itself towards individual objects, how can our consciousness grasp the pre-individual, time-constituting phenomena that make it up? At issue here is the status of Husserl’s own descriptions of consciousness and the temporal process. Does his theory undermine the possibility of the evidence he presents for it? • THE RELATION OF CONSCIOUSNESS TO THE EGO: Our sense of self involves more than our consciousness, more than the memories, perceptions, and anticipations that give it its content. It involves our sense as the subjective referent of every act, as the person to whom the world appears, as the one who is affected by the world and who acts with regard to it. What is the relation of this sense of self to our time consciousness? How does the simultaneous constitution of consciousness and its object result in the presence of the I that is the subject of consciousness? (shrink)
