Essentialism is widely regarded as a mistaken view of biological kinds, such as species. After recounting why (sections 2-3), we provide a brief survey of the chief responses to the “death of essentialism” in the philosophy of biology (section 4). We then develop one of these responses, the claim that biological kinds are homeostatic property clusters (sections 5-6) illustrating this view with several novel examples (section 7). Although this view was first expressed 20 years ago, and has received recent discussion (...) and critique, it remains underdeveloped and is often misrepresented by its critics (section 8). (shrink)

Discussions of whistleblowing and employee loyalty usually assume either that the concept of loyalty is irrelevant to the issue or, more commonly, that whistleblowing involves a moral choice in which the loyalty that an employee owes an employer comes to be pitted against the employee''s responsibility to serve public interest. I argue that both these views are mistaken and propose a third view which sees whistleblowing as entirely compatible with employee loyalty.

When natural selection theory was presented, much active philosophical debate, in which Darwin himself participated, centered on its hypothetical nature, its explanatory power, and Darwin's methodology. Upon first examination, Darwin's support of his theory seems to consist of a set of claims pertaining to various aspects of explanatory success. I analyze the support of his method and theory given in the Origin of Species and private correspondence, and conclude that an interpretation focusing on the explanatory strengths of natural selection theory (...) accurately reflects neither Darwin's own self-consciously held views, nor the nature of his support. Darwin's methodological and philosophical arguments were at once consistently empiricist and more sophisticated than such interpretations credit to him. (shrink)

Are thought experiments nothing but arguments? I argue that it is not possible to make sense of the historical trajectory of certain thought experiments if one takes them to be arguments. Einstein and Bohr disagreed about the outcome of the clock-in-the-box thought experiment, and so they reconstructed it using different arguments. This is to be expected whenever scientists disagree about a thought experiment's outcome. Since any such episode consists of two arguments but just one thought experiment, the thought experiment cannot (...) be the arguments. (shrink)

I suggest following Paul Feyerabend's own advice, and interpreting Feyerabend's work in light of the principles laid out by John Stuart Mill. A review of Mill's essay, On Liberty, emphasizes the importance Mill placed on open and critical discussion for the vitality and progress of various aspects of human life, including the pursuit of scientific knowledge. Many of Feyerabend's more unusual stances, I suggest, are best interpreted as attempts to play certain roles--especially the role of "defender of unpopular minority opinion"--that (...) are necessary to fulfilling Mill's conditions for rational exchange and optimal human development.

Artificial intelligence (AI) is an area of computer science that emphasizes the creation of intelligent machines or software that work and react like humans. Some of the activities computers with artificial intelligence are designed for include, Speech, recognition, Learning, Planning and Problem solving. Deep learning is a collection of algorithms used in machine learning, It is part of a broad family of methods used for machine learning that are based on learning representations of data. Deep learning is a technique used (...) to produce Pneumonia detection and classification models using x-ray imaging for rapid and easy detection and identification of pneumonia. In this thesis, we review ways and mechanisms to use deep learning techniques to produce a model for Pneumonia detection. The goal is find a good and effective way to detect pneumonia based on X-rays to help the chest doctor in decision-making easily and accuracy and speed. The model will be designed and implemented, including both Dataset of image and Pneumonia detection through the use of Deep learning algorithms based on neural networks. The test and evaluation will be applied to a range of chest x-ray images and the results will be presented in detail and discussed. This thesis uses deep learning to detect pneumonia and its classification. (shrink)

This paper examines the moral arguments for and against employees' blowing the whistle on illegal or immoral actions of their employers. It asks whether such professional dissidents are justified in disclosing wrongdoing by others while concealing their own identity. Part I examines the concept of anonymity, distinguishing it from two similar concepts — secrecy and privacy. Part II analyzes the concept of whistleblowing using recent definitions by Bok, Bowie and De George. Various arguments against anonymous whistleblowing are identified and evaluated. (...) The author concludes with a defense of the practice in terms of social benefits — primarily the redressing of wrongdoing. (shrink)

The flight to reference is a widely-used strategy for resolving philosophical issues. The three steps in a flight to reference argument are: (1) offer a substantive account of the reference relation, (2) argue that a particular expression refers (or does not refer), and (3) draw a philosophical conclusion about something other than reference, like truth or ontology. It is our contention that whenever the flight to reference strategy is invoked, there is a crucial step that is left undefended, and that (...) without a defense of this step, the flight to reference is a fatally flawed strategy; it cannot succeed in resolving philosophical issues. In this paper we begin by setting out the flight to reference strategy and explaining what is wrong with arguments that invoke the strategy. We then illustrate the problem by considering arguments for and against eliminative materialism. In the final section we argue that much the same problem undermines Philip Kitcher's attempt to defend scientific realism. (shrink)

Our aim in this paper is to bring the woefully neglected literature on predictive modeling to bear on some central questions in the philosophy of science. The lesson of this literature is straightforward: For a very wide range of prediction problems, statistical prediction rules (SPRs), often rules that are very easy to implement, make predictions than are as reliable as, and typically more reliable than, human experts. We will argue that the success of SPRs forces us to reconsider our views (...) about what is involved in understanding, explanation, good reasoning, and about how we ought to do philosophy of science.

Carl Gillett has defended what he calls the “dimensioned” view of the realization relation, which he contrasts with the traditional “flat” view of realization (2003, 2007; see also Gillett 2002). Intuitively, the dimensioned approach characterizes realization in terms of composition whereas the flat approach views realization in terms of occupiers of functional roles. Elsewhere we have argued that the general view of realization and multiple realization that Gillett advances is not able to discharge the theoretical duties of those relations (Shapiro (...) 2004, unpublished manuscript; Polger 2004, 2007, forthcoming). Here we focus on an internal objection to Gillett’s account and then raise some broader reasons to reject it. (shrink)

It is natural to think that our ordinary practices in giving explanations for our actions, for what we do, commit us to claiming that content properties are causally relevant to physical events such as the movements of our limbs and bodies, and events which these in turn cause. If you want to know why my body ambulates across the street, or why my arm went up before I set out, we suppose I have given you an answer when I say (...) that I wanted to greet a friend on the other side of the street, and thought that my arm's going up would be interpreted by him as a signal to stop for a moment. This widely held view might be disputed, but I shall not argue for it in this paper. I want to start with the view that our beliefs and desires and other propositional attitudes are causally relevant, in virtue of their modes and particular contents, to our movements, in order to investigate the consequences for analyses of thought content. For this purpose, I argue, in sec. II, for three necessary conditions on causal relevance: (a) a nomic sufficiency condition, (b) a logical independence condition, and (c) a screening-off condition. In sec. III, I apply these conditions to relational and functional theories of thought content, arguing that these theories cannot accommodate the causal relevance of content properties to our behaviour. I argue further that, on two plausible assumptions, one about the dependence of the mental on the physical, and the other about the availability in principle of causal explanations of our movements in terms of our non-relational physical properties, content properties can be causally relevant only if they are nomically type-correlated, relative to certain circumstances, with non-relational physical properties of our bodies. In sec. IV, I respond to a number of objections that might be advanced against this conclusion. (shrink)

Scientific realism says of our best scientific theories that (1) most of their important posits exist and (2) most of their central claims are approximately true. Antirealists sometimes offer the pessimistic induction in reply: since (1) and (2) are false about past successful theories, they are probably false about our own best theories too. The contemporary debate about this argument has turned (and become stuck) on the question, Do the central terms of successful scientific theories refer? For example, Larry Laudan (...) offers a list of successful theories that employed central terms that failed to refer, and Philip Kitcher replies with a view about reference in which the central terms of such theories did sometimes refer. This article attempts to break this stalemate by proposing a direct version of the pessimistic induction, one that makes no explicit appeal to a substantive notion or theory of reference. While it is premature to say that this argument succeeds in showing that realism is probably false, the direct pessimistic induction is not subject to any kind of reference-based objection that might cripple a weaker, indirect version of the argument. Any attempt to trounce the direct pessimistic induction with a theory of reference fails. (shrink)

An interpretation of Hegel's Philosophy of Subjective Spirit showing its continued relevance to contemporary issues in the philosophy of mind.

Previous discussions on the value of sport in remote locations have concentrated on 1) environmental and process concerns, with the rejection of competition and goal-directed or use oriented activity, or 2) the value of risk and dangerous sport for self-affirmation. It is argued that the value of risk in remote sport is in self-knowledge rather than self-affirmation and that risk in remote sport, while enhancing certain kinds of experience, is not necessary. The value of remote sport is in offering the (...) opportunity for experience that enhances the participants’ knowledge both of self and of the environment with which they interact. (shrink)

Kevin Corcoran offers an account of how one can be a physicalist about human persons, deny temporal gaps in the existence of persons, and hold that there is an afterlife. I argue that Corcoran's account both violates the necessity of metaphysical identity and implausibly makes an individual's existence dependent on factors wholly extrinsic to the individual. Corcoran's defence is considered, as well as Stephen Davis's suggestions on how an account like Corcoran's can defend itself against these concerns. It is shown, (...) however, that the difficulties remain in full force and, therefore, that Corcoran's account fails to reconcile physicalism, no gappy existence, and an afterlife. (shrink)

Text John Toland a jeho Křesťanství bez mystérií sestává ze dvou provázaných částí. První část představuje stručné biografické pojednání o Johnu Tolandovi (1670–1722), v němž se mimo jiné snažíme předložit obecný úvod do jeho myšlení. Druhá část pak nabízí první český překlad předmluvy k Tolandovu nejznámějšímu spisu Christianity not Mysterious (1696), který je považován za základní impulz deistické diskuze na Britských ostrovech.

I argue that understanding the self in terms of narrative construction does not preclude the possibility of error concerning one’s own self. Identity is a projection of first and second-order desires and a product of choice in relation to desire. Self-deceit appears in this connection as a response to an identity that one has constructed through choice and/or desire but not acknowledged in one’s self-account, reflecting a conflict between desires or a motivated failure to account. This analysis is applied primarily (...) to acknowledgement of one’s sexual identity. (shrink)

I respond to a hypothetical critique of sport, drawing on primarily post-modernist sources, that would view the high performance athlete in particular as a product of the application of technical disciplines of power and that opposes sport and play as fundamentally antithetical. Through extensive discussion of possible definitions of play, and of performance, I argue that although much of the critique is valid it confuses a method of sport for the whole of it. Play is indeed a noncompellable spontaneity, but (...) one that involves the improvisational transformation of the technical skills of a sport within the context of a dynamic situation. Technique is a condition of heightened play; it does not produce it. This also means that the best play is not undisciplined. Play and sport can exist apart, but both are better combined. (shrink)

<The definitive version is available at www.blackwell-synergy.com > -- In this paper I carve out a space between the concept of "the object" and the seemingly endless ways in which "the object" can be represented pictorially. I will call the aspect of the pictorial representation which is made possible by this space, the pictorial representation's "style". I will explore this space by drawing upon theories of pictorial representation, leaving out, for the sake of my purposes here, a consideration of the (...) artist's intention. That an attribution of "style" can be comprehensive while leaving out a consideration of artists' intentions, I will argue by adopting the conceptual framework of Paul Thom's theory of interpretation. Before embarking on my project, I begin with a brief overview of the rather slippery notion of "style". (shrink)

This essay expands upon the suggestion that Lessing's infamous ‘ditch’ is actually three ditches: temporal, metaphysical, and existential gaps. It examines the complex problems these ditches raise, and then proposes that Kierkegaard's Fragments and Postscript exhibit a similar triadic organizational structure, which may signal a deliberate attempt to engage and respond to Lessing's three gaps. Viewing the Climacean project in this way offers an enhanced understanding of the intricacies of Lessing's rationalist approach to both religion and historical truth, and illuminates (...) Climacus's subjective response to Lessing. (shrink)

According to Field’s influential incompleteness objection, Tarski’s semantic theory of truth is unsatisfactory since the definition that forms its basis is incomplete in two distinct senses: (1) it is physicalistically inadequate, and for this reason, (2) it is conceptually deficient. In this paper, I defend the semantic theory of truth against the incompleteness objection by conceding (1) but rejecting (2). After arguing that Davidson and McDowell’s reply to the incompleteness objection fails to pass muster, I argue that, within the constraints (...) of a non-reductive physicalism and a holism concerning the concepts of truth, reference and meaning, conceding Field’s physicalistic inadequacy conclusion while rejecting his conceptual deficiency conclusion is a promising reply to the incompleteness objection.

Reasoning about mental states and processes is important in various subareas of the legal domain. A trial lawyer might need to reason and the beliefs, reasoning and other mental states and processes of members of a jury; a police officer might need to reason about the conjectured beliefs and reasoning of perpetrators; a judge may need to consider a defendant's mental states and processes for the purposes of sentencing and so on. Further, the mental states in question may themselves be (...) about the mental states and processes of other people. Therefore, if AI systems are to assist with reasoning tasks in law, they may need to be able to reason about mental states and processes. Such reasoning is riddled with uncertainty, and this is true in particular in the legal domain. The article discusses how various different types of uncertainty arise, and shows how they greatly complicate the task of reasoning about mental states and processes. The article concentrates on the special case of states of belief and processes of reasoning, and sketches an implemented, prototype computer program (ATT-Meta) that copes with the various types of uncertainty in reasoning about beliefs and reasoning. In particular, the article outlines the system's facilities for handling conflict between different lines of argument, especially when these lie within the reasoning of different people. The system's approach is illustrated by application to a real-life mugging example. [NB: The date on the archived preprint avail via this Phil* page has an incorrect date, 2011, on it. The correct date is 2001.]. (shrink)

We use a neutrosophic set, instead of an intuitionistic fuzzy because the neutrosophic set is more general, and it allows for independent and partial independent components, while in an intuitionistic fuzzy set, all components are totally dependent. In this article, we present and demonstrate the concept of neutrosophic invariant subgroups. We delve into the exploration of this notion to establish and study the neutrosophic quotient group. Further, we give the concept of a neutrosophic normal subgroup as a novel concept.

Selective access and integration underlie much of our visual experience. This article describes several of the experimental techniques used to investigate these processes, and some of the major results achieved in our understanding of their operation.

How Heidegger criticizes and "locates" science, and some problems with what he is trying to do.

One of the benefits of hypertext in a connected digital environment is the ability to interlink documents. This was part of the hyper-text focused vision of the internet that Tim Berners-Lee was trying to create in the 1990s when he developed the World Wide Web.

The overarching thesis of this essay is that despite the etymological relationship between the word ‘philosophy’ and wisdom—the word ‘philosophos’, in Greek, means ‘lover of wisdom’—and irrespective of the longstanding tradition of identifying philosophers with ‘wise men’—mainline philosophy, historically, has had little interest in wisdom and has been preoccupied primarily with knowledge. Philosophy, if we are speaking of the mainline tradition, has had and continues to have more in common with the natural and social sciences than it does with the (...) humanities and liberal arts. In advancing this thesis, I divide the history of philosophy into three competing traditions: the mainline tradition of philosophy and two philosophical ‘countercultures,’ one conservative the other radical. At issue between these rival traditions is precisely the relative significance of knowledge and wisdom and their respective places in inquiry. I also provide an account of the distinction between knowledge and wisdom—which I argue is greater than has perhaps been appreciated—and between the natural and applied sciences, on the one hand, and the humanities and liberal arts on the other.

In this paper I examine Grace A. de Laguna’s theory of universals in its historical context and in relation to contemporary debates in analytic metaphysics. I explain the central features of her theory, arguing that her theory should be classified as a form of immanent realism and as a powers ontology. I then show in what ways her theory affords a theory of modality in terms of potentialities and discuss some of its consequences along the way.

The author examines the problem of motivation about future generations. He argues that though many philosophers think that direct motivations are problematic for future generations only, they are not unproblematic for the current generations too, and that the motivation problem can be solved if we consider the idea of “leaving the earth no worse.” He also shows why such an idea should be promoted and can motivate us to work in the best interests of current and future generations. The author (...) also contends that prioritizing the idea of “leaving the earth no worse” is not exclusively anthropocentric. (shrink)

The views of John Dewey and Kurt Vonnegut are often criticized for opposite reasons: Dewey’s philosophy is said to be naively optimistic while Vonnegut’s work is read as cynical. The standard debates over the views of the two thinkers cause readers to overlook the similarities in the way each approaches tragic experience. This paper examines Dewey’s philosophic account of time and meaning and Vonnegut’s use of time travel in his autobiographical novel Slaughterhouse-Five to illustrate these similarities. This essay demonstrates how (...) both Dewey and Vonnegut embrace the ameliorative possibilities of art for preserving individuality and meaning in the face of tragic experience. (shrink)

It is tough to relate visual perception or other achievements to physiological processing in the central nervous system. The diagrammatic, algebraic, and verbal pictures of how sights seem to Lehar do not advance understanding of how we manage to see what is in the world. There are well-known conceptual reasons why no such purely introspective approach can be productive.

In debates over life and death it is often said that one should err on the side of caution—that is, on the side of life. In light of the recent case of Terri Schiavo, it is explained how the “err-on-the-side-of-life” argument proceeds, and an objection to it is offered.

Copi's method of deduction is formalized and shown to be complete.

David Lewis objected to theories that posit necessary connections between distinct entities and to theories that involve a magical grasping of their primitives. In On the Plurality of Worlds, Lewis objected to nondescript ersatzism on these grounds. The literature contains several reconstructions of Lewis’ critique of nondescript ersatzism but none of these interpretations adequately address his main argument because they fail to see that Lewis’ critique is based on broader methodological considerations. I argue that a closer look at his methodology (...) reveals the broader objection he presented against nondescript ersatzism. This objection, I further argue, remains a challenge for the ersatzer who posits structure-less entities as possible worlds. (shrink)

A graph-theoretic account of logics is explored based on the general notion of m-graph (that is, a graph where each edge can have a finite sequence of nodes as source). Signatures, interpretation structures and deduction systems are seen as m-graphs. After defining a category freely generated by a m-graph, formulas and expressions in general can be seen as morphisms. Moreover, derivations involving rule instantiation are also morphisms. Soundness and completeness theorems are proved. As a consequence of the generality of the (...) approach our results apply to very different logics encompassing, among others, substructural logics as well as logics with nondeterministic semantics, and subsume all logics endowed with an algebraic semantics.

Health services internationally struggle to ensure health care is “person-centered” (or similar). In part, this is because there are many interpretations of “person-centered care” (and near synonyms), some of which seem unrealistic for some patients or situations and obscure the intrinsic value of patients’ experiences of health care delivery. The general concern behind calls for person-centered care is an ethical one: Patients should be “treated as persons.” We made novel use of insights from the capabilities approach to characterize person-centered care (...) as care that recognizes and cultivates the capabilities associated with the concept of persons. This characterization unifies key features from previous characterisations and can render person-centered care applicable to diverse patients and situations. By tying person-centered care to intrinsically valuable capability outcomes, it incorporates a requirement for responsiveness to individuals and explains why person-centered care is required independently of any contribution it may make to health gain.
