Two mechanisms are available for the repair of DNA double‐strand breaks (DSBs) in eukaryotic cells: homology directed repair (HDR) and non‐homologous end‐joining (NHEJ). While NHEJ is not restricted to a particular phase of the cell cycle, it is incapable of accurately repairing DBSs that have suffered a loss or gain of nucleotide sequence information. In contrast, HDR achieves accurate repair of such DSBs by use of a sister chromatid as a DNA template, but is restricted to cell cycle phases (S/G2) (...) when such templates are available. In this scheme, G1 cells appear to lack a mechanism for the accurate repair of certain DSBs, and an ability to use alternative templates would be highly advantageous. Considered here, therefore, is the possibility that RNA transcripts are used as templates for HDR. Potential mechanisms for transcript‐templated HDR, and ways in which it might be detected, are presented. BioEssays 28:78–83, 2006. © 2005 Wiley Periodicals, Inc. (shrink)

In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1) the nature of a mental disorder; 2) the definition of mental disorder; 3) the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4) the role (...) of pragmatic considerations in the construction of DSM-5; 5) the issue of utility of the DSM – whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6) the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part 1 of this article took up the first two questions. Part 2 took up the second two questions. Part 3 now deals with Questions 5 & 6. Question 5 confronts the issue of utility, whether the manual design of DSM-III and IV favors clinicians or researchers, and what that means for DSM-5. Our final question, Question 6, takes up a concluding issue, whether the acknowledged problems with the earlier DSMs warrants a significant overhaul of DSM-5 and future manuals. As in Parts 1 & 2 of this article, the general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.

In the conclusion to this multi-part article I first review the discussions carried out around the six essential questions in psychiatric diagnosis – the position taken by Allen Frances on each question, the commentaries on the respective question along with Frances’ responses to the commentaries, and my own view of the multiple discussions. In this review I emphasize that the core question is the first – what is the nature of psychiatric illness – and that in some manner all further (...) questions follow from the first. Following this review I attempt to move the discussion forward, addressing the first question from the perspectives of natural kind analysis and complexity analysis. This reflection leads toward a view of psychiatric disorders – and future nosologies – as far more complex and uncertain than we have imagined. (shrink)

Part I of this article will take up the first two questions. With the first question, invited commentators express a range of opinion regarding the nature of psychiatric disorders, loosely divided into a realist position that the diagnostic categories represent real diseases that we can accurately name and know with our perceptual abilities, a middle, nominalist position that psychiatric disorders do exist in the real world but that our diagnostic categories are constructs that may or may not accurately represent the disorders out there, and finally a purely constructivist position that the diagnostic categories are simply constructs with no evidence of psychiatric disorders in the real world. The second question again offers a range of opinion as to how we should define a mental or psychiatric disorder, including the possibility that we should not try to formulate a definition. The general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.

Question 3 deals with the question as to whether DSM-V should assume a conservative or assertive posture in making changes from DSM-IV. That question in turn breaks down into discussion of diagnoses that depend on, and aim toward, empirical, scientific validation, and diagnoses that are more value-laden and less amenable to scientific validation. Question 4 takes up the role of pragmatic consideration in a psychiatric nosology, whether the purely empirical considerations need to be tempered by considerations of practical consequence. As in Part 1 of this article, the general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.

Abstract:Recent work on the subject speaks to the importance trust has for firm performance (e.g., Hagen and Choe, 1999; Hill, 1995). Yet little work has been done to show how context affects the ability of firms to create trust in relationships with key stakeholders. This paper looks at how the institutional environment may affect the performance of different strategies for managing firm-stakeholder relationships, and in turn, how this affects firm performance. The authors put forward propositions that build on these theoretical (...) insights and offer prospects for future empirical work. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Dimensions of Agency in Lincoln’s Second InauguralAndrew C. HansenSix days before he delivered his Second Inaugural Address, Abraham Lincoln strode into his White House office. Greeting him were G. B. Lincoln, John A. Bingham, and Francis Carpenter, the last of whom had been living with Lincoln in the White House for six months, painting a portrait of the president reading the Emancipation Proclamation to the cabinet. It is Carpenter's (...) delineation of the president's entrance that contains the "only known description of the preliminaries of the Second Inaugural" (Barondess 1954, 62). "Mr. Lincoln came in through the side passage which had lately been constructed," Carpenter writes, "holding in his hand a roll of manuscripts." Lincoln turned to his guests and quipped, "Lots of wisdom in that document, I suspect; it is what will be called my 'second inaugural' " (quoted in Barondess, 62).The content and modesty of Carpenter's description of the "preliminaries of the Second Inaugural" give the rhetorical critic a telling preview of what might be discovered in a reading of Lincoln's composition of that manuscript. The understatement in the length and simplicity of the address subtly and poignantly charms the reader. And there is "lots of wisdom" in the Second Inaugural: along with the Gettysburg Address, it contains the words of Lincoln that most abide. In a letter to an admiring Thurow Weed, who had penned Lincoln that his inaugural was "the neatest but the most pregnant and effective use to which the English Language was ever put," Lincoln wrote that he "expected" the Second Inaugural to "wear as well as—perhaps better than—anything I have ever produced" (quoted in Barondess 1954, 78).Underscoring Lincoln's perspicacity when he wrote to Weed that he "expected" the speech to "wear well," Carl Schulz's designation of the address as a "sacred poem" and the frequency with which that epithet is quoted by other critics confirm Lincoln's assessment of the oratorical endurance [End Page 223] of the piece. The estimation of the rhetorical durability of the address is perhaps best proven by its ability to withstand the polemics of its detractors, both immediately after its delivery and in successive generations, and the encomia of its admirers, both the obscure journalists and the renowned poets.1 Lately, only praise surrounds the Second Inaugural. Ronald C. White's thorough overview of the Second Inaugural's basic stylistic characteristics and how the oration resonates within Lincoln's social, political, and intellectual context is modestly entitled Lincoln's Greatest Speech (2002). In the last line of Lincoln at Gettysburg, Wills concludes that the Second Inaugural "is the only speech worthy to stand with" the Gettysburg Address (1992, 189) and later argues in the Atlantic Monthly that Lincoln "was at the peak of his creativity when he wrote the Second Inaugural Address" (1999, 70). The Second Inaugural seemingly speaks beyond its content and situation.Contained within the aura of adoration that surrounds the Second Inaugural is a significant charge to the rhetorical critic: what is it particularly about the address that sustains its agency and permits it to escape the evanescence accorded to most rhetorical efforts? When the agency of discourse helps to eliminate or extenuate the immediate exigency that calls forth that speech, it usually becomes remanded to the annals of history and is examined by the public or by scholars only when that historical nidus forces itself back upon the public's or the scholar's attention. The speech is exhausted by its situation and swallowed by its surrounding and future events. There are, however, those speeches like the Gettysburg Address and the Second Inaugural that practice their persuasion on audiences beyond the immediate exigency. They persist, they talk to us still, and their agency endures. Why is this true of Lincoln's Second Inaugural? This is the question that motivates my close reading of Lincoln's speech; and, as I hope to demonstrate, it is only through a close reading that such a question even makes sense. After explicating the scholarship that the Second Inaugural has generated and the critical assumptions that drive my close textual analysis, the essay will proceed with the work... (shrink)

This paper explores the subject of ethics expertise. We suggest that this is a topic which has been badly neglected despite ongoing discussions about subjects which presuppose a particular conception of expertise (e.g., codes of conduct, certification requirements). In addition, given significant challenges to any conception of ethical expertise, we try to determine whether it is possible to provide a meaningful and substantive account of it. The paper moves from more abstract discussion of the idea to grounding a particular model, (...) providing substance to it, and discussing specific traits or qualities of ethics experts. (shrink)

Despite the importance of extrapair copulation (EPC) in human evolution, almost nothing is known about the design features of EPC detection mechanisms. We tested for sex differences in EPC inference-making mechanisms in a sample of 203 young couples. Men made more accurate inferences (φmen = 0.66, φwomen = 0.46), and the ratio of positive errors to negative errors was higher for men than for women (1.22 vs. 0.18). Since some may have been reluctant to admit EPC behavior, we modeled how (...) underreporting could have influenced these results. These analyses indicated that it would take highly sex-differentiated levels of underreporting by subjects with trusting partners for there to be no real sex difference. Further analyses indicated that men may be less willing to harbor unresolved suspicions about their partners’ EPC behavior, which may explain the sex difference in accuracy. Finally, we estimated that women underreported their own EPC behavior (10%) more than men (0%). (shrink)

We submit this brief in support of the Nonhuman Rights Project’s efforts to secure habeas corpus relief for the elephant named Happy. We reject arbitrary distinctions that deny adequate protections to other animals who share with protected humans relevantly similar vulnerabilities to harms and relevantly similar interests in avoiding such harms. We strongly urge this Court, in keeping with the best philosophical standards of rational judgment and ethical standards of justice, to recognize that, as a nonhuman person, Happy should be (...) released from her current confinement and transferred to an appropriate elephant sanctuary, pursuant to habeas corpus.

It is often assumed that engaging in a one‐on‐one dialogue with a tutor is more effective than listening to a lecture or reading a text. Although earlier experiments have not always supported this hypothesis, this may be due in part to allowing the tutors to cover different content than the noninteractive instruction. In 7 experiments, we tested the interaction hypothesis under the constraint that (a) all students covered the same content during instruction, (b) the task domain was qualitative physics, (c) (...) the instruction was in natural language as opposed to mathematical or other formal languages, and (d) the instruction conformed with a widely observed pattern in human tutoring: Graesser, Person, and Magliano's 5‐step frame. In the experiments, we compared 2 kinds of human tutoring (spoken and computer mediated) with 2 kinds of natural‐language‐based computer tutoring (Why2‐Atlas and Why2‐AutoTutor) and 3 control conditions that involved studying texts. The results depended on whether the students' preparation matched the content of the instruction. When novices (students who had not taken college physics) studied content that was written for intermediates (students who had taken college physics), then tutorial dialogue was reliably more beneficial than less interactive instruction, with large effect sizes. When novices studied material written for novices or intermediates studied material written for intermediates, then tutorial dialogue was not reliably more effective than the text‐based control conditions.

This article reviews models of the cerebellum and motor learning, from the landmark papers by Marr and Albus through those of the present time. The unique architecture of the cerebellar cortex is ideally suited for pattern recognition, but how is pattern recognition incorporated into motor control and learning systems? The present analysis begins with a discussion of exactly what the cerebellar cortex needs to regulate through its anatomically defined projections to premotor networks. Next, we examine various models showing how the (...) microcircuitry in the cerebellar cortex could be used to achieve its regulatory functions. Having thus defined what it is that Purkinje cells in the cerebellar cortex must learn, we then evaluate theories of motor learning. We examine current models of synaptic plasticity, credit assignment, and the generation of training information, indicating how they could function cooperatively to guide the processes of motor learning.

As he neared 80 Russell was more financially secure than he had been for decades. But to remain so he needed to maintain his prodigious output as a writer, broadcaster and lecturer (see Papers 26, forthcoming). Meanwhile, the breakdown of his third marriage threatened to undermine his much-improved financial position. The monetary concerns addressed in both the text prepared by Russell and the related commentary hint at a lifetime’s scrupulous regard for his personal finances.

Boarding school is a major educational option for many students (e.g., students living in remote areas, or whose parents are working interstate or overseas, etc.). This study explored the motivation, engagement, and achievement of boarding and day students who are educated in the same classrooms and receive the same syllabus and instruction from the same teachers (thus a powerful research design to enable unique comparisons). Among 2,803 students (boardingn= 481; dayn= 2,322) from 6 Australian high schools and controlling for background (...) attributes and personality, we found predominant parity between boarding and day students in their motivation, engagement, and achievement. We also found that classroom-average motivation, engagement, and achievement was not significantly affected by the number of boarders (relative to day students) in the classroom. In addition, the effects of boarding were generally not moderated by students’ background or personality attributes. We conclude that boarders have academic opportunities and outcomes that are comparable to their day student counterparts. Implications for students, teachers, and parents are discussed. (shrink)

In this report, we describe the case of a patient who has remained in a comatose state for more than one year after a traumatic and hypoxic brain injury. This state, which we refer to as long-lasting coma (LLC), may be a disorder of consciousness with significantly different features from those of conventional coma, the vegetative state, or brain death. On the basis of clinical, neurophysiological and neuroimaging data, we hypothesize that a multilevel involvement of the ascending reticular activating system (...) is required in LLC. This description may be useful for the identification of other patients suffering from this severe disorder of consciousness, which raises important ethical issues. (shrink)

Ian Barbour sees four ways to relate science and religion: (1) conflict, (2) disjunction or independence, (3) dialogue, and (4) synthesis or integration. David Burrell posits three ways to construe religious language, as (a) univocal, (b) equivocal, or (c) analogous. The paper contends that Barbour’s (1) and (4) presuppose Burrell’s (a), Barbour's (2) presupposes Burrell’s (b), and Barbour’s (3) presupposes Burrell’s (c), and it explores some of the implications for each alternative.

ObjectiveTo prospectively study the cingulate cortex for the localization and role of the grasping action in humans during electrical stimulation of depth electrodes.MethodsAll the patients with intractable focal epilepsy and a depth electrode stereotactically placed in the cingulate cortex, as part of their pre-surgical epilepsy evaluation from 2015 to 2017, were included. Cortical stimulation was performed and examined for grasping actions. Post-implantation volumetric T1 MRIs were co-registered to determine the exact electrode position.ResultsFive patients exhibited contralateral grasping actions during electrical stimulation. (...) All patients had electrodes implanted in the ventral bank of the right cingulate sulcus adjacent to the vertical anterior commissure line. Stimulation of other electrodes in adjacent regions did not elicit grasping.ConclusionGrasping action elicited from a localized region in the mid-cingulate cortex directly supports the concept of the cingulate cortex being crucially involved in the grasping network. This opens an opportunity to explore this region with deep brain stimulation as a motor neuromodulation target for treatment in specific movement disorders or neurorehabilitation. (shrink)

The extended Church-Turing thesis posits that any computable function can be calculated efficiently by a probabilistic Turing machine.

Interleukin 1β‐converting enzyme (ICE)‐like proteases (caspases) play an important role in programmed cell death (apoptosis), and elucidating the consequences of their proteolytic activity is central to our understanding of the molecular mechanisms of cell death. Diverse structural and regulatory proteins and enzymes, including protein kinase Cδ, the retinoblastoma protein (a protein involved in cell survival), the DNA repair enzyme DNA‐dependent protein kinase and the nuclear lamins, undergo specific and limited endoproteolytic cleavage by various caspases during apoptosis. Since individual caspases can (...) cleave multiple substrates, the consequences of cleavage of only a single substrate are still poorly understood. Nevertheless, proteolytic activation of protein kinase Cδ may be an important early step in the cell death pathway, and cleavage of the retinoblastoma protein could suppress its cell survival function, whereas proteolytic inactivation of DNA repair enzymes might compromise the ability of the cell to reverse DNA fragmentation. On the other hand, cleavages of nuclear and cytoplasmic structural proteins (e.g. the lamins and Gas2) appear to be required for or contribute to the dramatic rearrangements in cellular architecture that are necessary for the completion of the cell death process. An emerging theme is that parallel and sequential proteolytic activation and inactivation of key protein substrates occurs during the multiple steps of apoptosis. (shrink)

Progressive supranuclear palsy is a movement disorder with prominent tau neuropathology. Brain diseases with abnormal tau deposits are called tauopathies, the most common of which is Alzheimer's disease. Environmental causes of tauopathies include repetitive head trauma associated with some sports. To identify common genetic variation contributing to risk for tauopathies, we carried out a genome-wide association study of 1,114 individuals with PSP and 3,247 controls followed by a second stage in which we genotyped 1,051 cases and 3,560 controls for the (...) stage 1 SNPs that yielded P ≤ 10-3. We found significant previously unidentified signals associated with PSP risk at STX6, EIF2AK3 and MOBP. We confirmed two independent variants in MAPT affecting risk for PSP, one of which influences MAPT brain expression. The genes implicated encode proteins for vesicle-membrane fusion at the Golgi-endosomal interface, for the endoplasmic reticulum unfolded protein response and for a myelin structural component. © 2011 Nature America, Inc.

_Winner of the Fabian Dorsch ESA Essay Prize._ Julian Dodd defends the view that, in musical work-performance practice, interpretive authenticity is a more fundamental value than score compliance authenticity. According to him, compliance with a work’s score can be sacrificed in cases where it conflicts with interpretative authenticity. Stephen Davies and Andrew Kania reject this view, arguing that, if a performer intentionally departs from a work’s score, she is not properly instantiating that work and hence not producing an authentic (...) performance of it. I argue that this objection fails. A detailed analysis of work-performance practice reveals, first, that the normative scope of interpretive authenticity encompasses the practice of composing musical versions and that, second, when performers sacrifice score compliance to maximize interpretive authenticity, they are performing the target work by means of performing a version of it. By means of the nested types theory, I then show how performances produced in this way can be properly formed instances, and hence authentic performances, of their target work. (shrink)

The determination thesis is the idea that art-ontological facts are determined by the folk ontological conception of artworks embedded in our artistic practices. From this thesis, descriptivism in the metaontology of art has been often characterized as the view that the task of art-ontology is to describe that folk conception. Amie Thomasson and Andrew Kania provide two paradigmatic accounts within this path. In this paper, I argue that this descriptivist approach is ungrounded because the determination thesis suffers from presupposition (...) failure. It presupposes that, whenever there is a practice of producing and appreciating artworks, there is also a folk ontological conception about those artworks. This presupposition, an implicit premise in Thomasson's and Kania's accounts, will be revealed as false, paying attention to the way artistic practices have evolved. I will conclude that descriptivism should abandon this approach and embrace metaontological realism if it aims to be a plausible view. (shrink)

IntroductionDespite the need for trained physician ethicists, fellowships in clinical ethics are limited and primarily offered to thosewho have completed a graduate degree. The standardization of credentialing for clinical ethics consultants (CECs) and the restructuring of undergraduate medical education allow innovative models to train CECs that can provide an expanded opportunity for formal ethics training at an earlier stage.MethodsAt the University of Michigan Medical School we developed, implemented, and evaluated a pre-doctoral clinical ethics fellowship program from 2017 to 2019 for (...) senior medical students, designed to meet established competencies for CECs. Consultation notes from the beginning and end of the fellowship program were randomly selected for each fellow and independently rated by two faculty ethicists who used the validated Ethics Consultation Quality Assessment Tool (ECQAT).1 Inter rater reliability and trends in scores over time were calculated.ResultsThree students successfully completed the fellowship at the University of Michigan Medical School, conducted at least 50 formal ethics consultations, and spent approximately 40 hours a week on service for a minimum of six months. All students finished the fellowship with teaching and policy development experience, first-authored peer-reviewed manuscripts, and national presentations. The fellows demonstrated improvement in their ECQAT overall holistic rating score; all ended their fellowship with a holistic score of adequate or above. There was 92 percent agreement between raters withrespect to the acceptability of the fellows’ ethics consult notes. Two fellows have taken and passed the Healthcare Ethics Consultant-Certification (HEC-C) exam offered by the American Society for Bioethics and Humanities (ASBH).ConclusionsIntegration of a pre-doctoral fellowship model that meets professional certification standards for clinical ethics consultation creates an opportunity for medical students to become trained CECs early in their career.

A novel photon-based proton model is developed. A proton’s ground state is assumed to be coherent to the degree that all of its mass-energy precipitates into a single uncharged spherical structure. A quantum vortex, initiated by the strong force, but sustained in the proton’s ground state by the circular Unruh effect and a spherical Rindler horizon, is proposed to confine the proton’s mass-energy in its ground state. A direct connection between the circular Unruh effect, the zitterbewegung effect, spin, and general (...) relativity is proposed. Such a structure acts as an uncharged zitterbewegung fermion, and may explain neutrino mass. A ground-state proton’s central zitterbewegung fermion is assumed to be surrounded by a halo of charge shells of both signs. Virtual photon standing waves are assumed to synchronize the inner shell with the central zitterbewegung fermion. The charge shells are proposed to be associated with isospin and proton g-factor. There are only two model inputs—proton mass and quantized electronic charge—and just one adjustable parameter. The adjustable parameter, reduced only by about 0.4% from an initial estimate, provides the proton’s experimentally determined magnetic moment to arbitrary precision. The resulting modeled proton charge radius agrees very well with the 2018 CODATA value. Magnetic moment and charge radius are calculated algebraically in a manner easily understood by undergraduate physics students. This proposed ground-state proton model could be considered a low-energy approximation to a full quantum chromodynamical proton model. (shrink)

Nemesio G. C. Puy argues that the "nested types" ontology of works of Western classical music can solve recent disagreements about such works' authentic performance. I raise several objections to his argument.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 39.1 (2001) 77-99 [Access article in PDF] Malebranche's Distinction Between General and Particular Volitions Andrew Pessin "God needs no instruments to act," Malebranche writes in Search; "it suffices that He wills in order that a thing be, because it is a contradiction that He should will and that what He wills should not happen. Therefore, His power is His will." 1 God (...) acts by willing; so much is clear. But Malebranche goes further, especially in his Treatise, by asserting that (i) only in miracles and the initial creation does God act by "particular volitions," while (ii) God ordinarily acts in nature via laws or "general volitions." This distinction between general and particular volitions is central to Malebranche's theories of divine activity, theodicy, and occasionalism. Nevertheless, I will argue, it has been almost universally misunderstood.The two standard interpretations of Malebranche's expressions "general volition" and "particular volition" are these: (GC) A "general volition" for Malebranche is one whose content is general; a "particular volition" is one whose content is particular. [End Page 77](PC) All divine volitions have particular contents; but a "general volition" is one which is in accord with general laws, while a "particular volition" is one not in accord with general laws. 2Andrew Black offers the following two schemata for volition contents, where (B) also provides the general form of laws of nature: A: Let c be F at t. B: For all created substances x and y and for every time t1, if x is G at t1and x bears relation R to y then there is a time t2 such that t2 bears relation T to t1 and y is F at t2. 3(A) is "particular" insofar as it represents a particular state of affairs, involving a particular substance in a mode at a time; (B) is general in making no such reference. According to (GC), then, when Malebranche's God acts by "general volitions," He has volitions whose content is of the form of (B) (specifically, a law of nature); when He acts by particular volitions His volitions are of the form of (A). According to (PC), both general and particular volitions are of the form of (A), while the former are in accord with laws of nature and the latter aren't.To simplify matters, I will focus on God's activity in the material world; the laws of nature in question will usually be the laws of motion. Further, to avoid terminological confusion, I will refer to volitions of the form of (A) as "particular content volitions," and those of (B) as "general content volitions." The issue before us then is: When Malebranche's God acts by "general volitions," are these general content volitions or particular content volitions? Proponents of (GC) support the former; those of (PC) the latter.Unhappily, almost everything Malebranche says directly on the subject can be interpreted either way. 4 (I'll speculate why at the end.) And admittedly, what Malebranche says more broadly about natural laws and divine volitions is often suggestive of (GC)—so it is no surprise that almost all recent commentators adopt (GC), usually simply assuming it without argument. Still, I shall argue that if one of the interpretations is correct, it is (PC). [End Page 78]My plan in this paper: (1) Offer some prima facie support for (PC); (2) Provide four arguments that (PC) either fits better with, or is alone consistent with, various Malebranchean doctrines; (3) Reply to some recent objections against (PC); (4) Argue that Malebranche's direct reply to Arnauld supports (PC); (5) Offer a conclusion and final thought. 1. Some Prima Facie Support For (PC) Let me first note that Steven Nadler offers various passages which do at least suggest (PC). 5 But that evidence, while strong, is not alone conclusive. For one thing, those passages can perhaps be accommodated by (GC); 6 for another, there are many passages which suggest (GC). So we must go further.Consider, then, Malebranche's primary concern in the Treatise, the... (shrink)

Are the characteristics and relationships among spatio-temporal entities "real" or are they simply conventional terms that note similarities among things in the world but lack any reality of their own? Or if they are real, what sort of reality do they have? Do we live in a world of causes and effects, or is this relation a useful contrivance for our convenience? What is the nature of this "I" that we invoke when referring to ourselves? Is it body? Mind? Both? (...) Neither? And once its nature is understood, what can be said of the choices it makes? Are they really ours, freely made by an independent will? Or is each choice determined more by the internal makeup of the "I" we happen to be and the social/environmental circumstances in which this "I" finds itself, rather than by any act of will? But if each of us "could not have chosen otherwise" than we have, are we no better than the machines we construct? Then again, maybe some of our more advanced machines should be considered conscious entities? Introduction to Metaphysics: The Fundamental Questions presents these and other intriguing questions, many of which have challenged philosophers from antiquity to the present in their efforts to speculate on the nature of what is real. Often filled with twists and turns, dark corners and hidden recesses, this journey of discovery is an exciting excursion into the depths of human understanding. As guides for this intellectual journey editor Andrew Schoedinger has chosen an impressive array of creative and thought-provoking philosophers: Peter Abelard, Aristotle, Renford Bambrough, George Berkeley, Joseph Butler, Rudolf Carnap, Roderick Chisholm, R.G. Collingwood, Arthur Danto, Donald Davidson, Rene Descartes, C.J. Ducasse, Alvin I. Goldman, Keith Gunderson, David Hume, John Locke, Alasdair MacIntyre, A.I. Melden, John Stuart Mill, D.F. Pears, Hilary Putnam, Anthony Quinton, Bertrand Russell, Michael Scriven, Sydney Shoemaker, P. F. Strawson, Richard Taylor, and others. This volume is a unique invitation to join a distinguished group of theorists as they tackle tough questions concerning the existence of universals, the nature of causation, understanding personal identity, the tangled web of free will, and the challenges posed by the advent of artificial intelligence.
