Métaphysique M 10 est le seul endroit où Aristote fournit une solution à la “plus grande difficulté” du Livre B: si les principes des substances sont particuliers, mais que les objets de la connaissance scientifique doivent être universels, comment peut-il y avoir une connaissance scientifique de ces principes? Aristote répond que, en un sens important, la connaissance scientifique porte sur des choses particuliers. L’article montre pourquoi cette solution ne compromet pas le compte rendu officiel d’Aristote sur la connaissance scientifique, ni (...) n’assimile la connaissance scientifique à la perception, ni ne présuppose une conception sophistiquée des formes (comme étant soit particulières en elles-mêmes, soit neutres en ce qui concerne l’universalité et la particularité). La solution d’Aristote en M 10 peut plutôt être comprise dans le contexte de son analyse de la pensée géométrique en Θ 9. À différents moments, le géomètre doit choisir une actualisation particulière du potentiel inhérent à la figure concernée, mais il doit le faire d’une manière qui permette de saisir ce potentiel dans sa pleine universalité. L’article explore la promesse d’Aristote (le plus explicitement dans Sur la mémoire 1) de prendre l’interaction entre l’universalité et la particularité dans les diagrammes géométriques comme modèle pour la pensée scientifique en général.

One of Plato’s central tenets is that we can know forms. In Parmenides 133b4–134b5, Plato presents an argument whose sceptical conclusion is that we can’t know forms. Although he indicates that the argument doesn’t succeed, he also says it’s difficult to explain how it fails. Commentators have suggested a variety of flaws. I argue that the argument can be defended against some, though not all, of the alleged flaws. But I also argue that Plato hints at a crucial distinction that (...) hasn’t been brought to bear in this context, and that indeed he is sometimes thought not to draw: that between the content and object of knowledge. Once we are clear about this distinction, we can see that the sceptical argument doesn’t imply that we can’t know forms. (shrink)

ABSTRACT The extant attempts in the literature to refute the greatest difficulty argument in the Parmenides have focused on denying the parallelism between the pros relations among Forms and those among particulars. However, these attempts are unsatisfactory, for the argument can reach its conclusion that we cannot know any Forms without relying on this parallelism. I argue that a more effective strategy is to deny the more essential premise that the knowledge-object relation is a pros relation. This premise (...) is false because pros relations require definitional and ontological codependence between the relata, and the knowledge-object relation does not satisfy this reciprocity condition. RÉSUMÉ Les tentatives existantes dans la littérature de réfuter l'argument de la plus grande difficulté dans le Parménide ont surtout entrepris de nier le parallélisme entre les relations de type pros entre les Formes et celles entre les particuliers. Par contre, ces tentatives sont insatisfaisantes, parce que l'argument peut mener à sa conclusion selon laquelle on ne peut connaître les Formes sans s'appuyer sur ce parallélisme. Je soutiens qu'une stratégie plus efficace consiste à nier la prémisse plus essentielle selon laquelle la relation objet-connaissance est une relation de type pros. Cette prémisse est fausse parce que les relations de type pros requièrent une codépendance définitionnelle et ontologique entre les relata, et la relation objet-connaissance ne satisfait pas à cette condition de réciprocité.

This article considers Bentham's response to the criticism of utilitarianism that it allows for and may even require the sacrifice of some members of society in order to increase overall happiness. It begins with the contrast between the principle of utility and the contrasting principle of sympathy and antipathy to show that Bentham regarded the main achievement of his principle as overcoming the subjectivity he found in all other philosophical theories. This subjectivism, especially prevalent in theories of rights, might well (...) lead to the sacrifice of the individual. The principle of utility was presented as an ‘objective’ theory that avoided the difficulties of other moral and political theories. The article also considers the importance of universally applicable ends, such as security and equality, as part of the principle of utility, and especially Bentham's view of maximizing pleasure as being a distributive rather than an aggregative idea. The article concludes by criticizing H. L. A. Hart's interpretation of the role of equality and rights in Bentham and John Stuart Mill, and argues that Mill's doctrine of moral rights builds on foundations originally established by Bentham, foundations which would preclude the sacrifice of individuals.

Important examples of $\Pi^0_1$ classes of functions $f \in {}^\omega\omega$ are the classes of sets (elements of ω 2) which separate a given pair of disjoint r.e. sets: ${\mathsf S}_2(A_0, A_1) := \{f \in{}^\omega2 : (\forall i < 2)(\forall x \in A_i)f(x) \neq i\}$ . A wider class consists of the classes of functions f ∈ ω k which in a generalized sense separate a k-tuple of r.e. sets (not necessarily pairwise disjoint) for each k ∈ ω: ${\mathsf S}_k(A_0,\ldots,A_k-1) := (...) \{f \in {}^\omega k : (\forall i < k) (\forall x \in A_i) f(x) \neq i\}$ . We study the structure of the Medvedev degrees of such classes and show that the set of degrees realized depends strongly on both k and the extent to which the r.e. sets intersect. Let ${\mathcal S}^m_k$ denote the Medvedev degrees of those ${\mathsf S}_k(A_0,\ldots,A_{k-1})$ such that no m + 1 sets among A 0,...,A k-1 have a nonempty intersection. It is shown that each ${\mathcal S}^m_k$ is an upper semi-lattice but not a lattice. The degree of the set of k-ary diagonally nonrecursive functions $\mathsf{DNR}_k$ is the greatest element of ${\mathcal S}^1_k$ . If 2 ≤ l < k, then 0 M is the only degree in ${\mathcal S}^1_l$ which is below a member of ${\mathcal S}^1_k$ . Each ${\mathcal S}^m_k$ is densely ordered and has the splitting property and the same holds for the lattice ${\mathcal L}^m_k$ it generates. The elements of ${\mathcal S}^m_k$ are exactly the joins of elements of ${\mathcal S}^1_i$ for $\lceil{k \over m}\rceil \leq i \leq k$. (shrink)

In the 19th century, the conflict thesis was forged to explain the science-religion relationship. This thesis presents religion as an obstacle to the development of science. Andrew White publishes a book that is at the origin of this thesis and Charles S. Peirce writes a review of this book in which he shows that there is nothing in religion that opposes scientific progress, but points to four human characteristics that offer difficulties in the face of radical novelties. It is interesting (...) to note how while the conflict thesis was forged, one of the greatest thinkers already shows the weakness of this thesis. (shrink)

Naïve realism, often overlooked among philosophical theories of perception, has in recent years attracted a surge of interest. Broadly speaking, the central commitment of naïve realism is that mind-independent objects are essential to the fundamental analysis of perceptual experience. Since the claims of naïve realism concern the essential metaphysical structure of conscious perception, its truth or falsity is of central importance to a wide range of topics, including the explanation of semantic reference and representational content, the nature of phenomenal consciousness, (...) and the basis of perceptual justification and knowledge. One of the greatest difficulties surrounding discussions of naïve realism, however, has been lack of clarity concerning exactly what affirming or denying it entails. In particular, it is sometimes unclear how naïve realism is related to the claim that perceptual experience is in some sense direct or unmediated, and also to what extent the view is compatible with another widely discussed thesis in the philosophy of perception, the claim that perceptual experiences are states with representational content. In this essay, I discuss how recent work on these issues helps to clarify both the central commitments of naïve realism, as well as its relation to representationalist theories of perception. Along the way, I will attempt to shed light on the different ways in which each approach tries to address the various theoretical challenges facing a philosophical theory of perception, and also to assess the prospects for views that attempts to combine features of each approach.

In order to fulfill ABET requirements, Northern Arizona University’s Civil and Environmental engineering programs incorporate professional ethics in several of its engineering courses. This paper discusses an ethics module in a 3rd year engineering design course that focuses on the design process and technical writing. Engineering students early in their student careers generally possess good black/white critical thinking skills on technical issues. Engineering design is the first time students are exposed to “grey” or multiple possible solution technical problems. To identify (...) and solve these problems, the engineering design process is used. Ethical problems are also “grey” problems and present similar challenges to students. Students need a practical tool for solving these ethical problems. The step-wise engineering design process was used as a model to demonstrate a similar process for ethical situations. The ethical decision making process of Martin and Schinzinger was adapted for parallelism to the design process and presented to students as a step-wise technique for identification of the pertinent ethical issues, relevant moral theories, possible outcomes and a final decision. Students had greatest difficulty identifying the broader, global issues presented in an ethical situation, but by the end of the module, were better able to not only identify the broader issues, but also to more comprehensively assess specific issues, generate solutions and a desired response to the issue.

Perhaps the greatest difficulty confronting any interpreter of Peirce is the seeming chaos of doctrines, investigations, points of view, and original ideas found in Peirce's writings. There are in general two possible treatments of Peirce's philosophical work: the eclectic, in which Peirce is presented as a "fox," or a brilliant dabbler; the thematic, in which Peirce is seen as a "hedgehog," or a resolute, synoptic thinker whom circumstances prevented from achieving a final unification. Apel's Charles S. Peirce: From (...) Pragmatism to Pragmaticism takes the latter tack, seeing Peirce as engaged in a life-long investigation into the foundations and consequences of pragmatism and semiotics. All other inquiries are made ancillary to these, including Peirce's logical work. For Apel, the unifying thread is Peirce's encounter and dialogue with Kant's transcendental philosophy. Consequently, Peirce is seen as the founder of what Apel calls "transcendental semiotic or transcendental pragmatics". This view of Peirce has the interesting effect of making it seem that Peirce's work has perhaps more in common with Ernst Cassirer's, than it does with William James's. (shrink)

According to Frege, we need a criterion for recognising when different sentences express the same thought to make progress in logic. He himself hedged his own equipollence criterion with a number of provisos. In the literature on Frege, little attention has been paid to the problems these provisos raise. In this paper, I will argue that Fregeans have ignored these provisos at their peril. For without these provisos, Frege’s criterion yields wrong results; but with the provisos in place, it is (...) of no use for Frege’s purposes. This is connected to what Frege took to be the ‘greatest difficulty for philosophy’: natural language sentences don’t just express thoughts; they convey evaluations and communicative hints. Because of this, Frege’s recognition criterion for thoughts cannot be applied to them and we cannot make logical progress by ‘recognising a thought in different linguistic guises’. (shrink)

These remarks take up the reflexive problematics of Being and Nothingness and related texts from a metalogical perspective. A mutually illuminating translation is posited between, on the one hand, Sartre’s theory of pure reflection, the linchpin of the works of Sartre’s early period and the site of their greatest difficulties, and, on the other hand, the quasi-formalism of diagonalization, the engine of the classical theorems of Cantor, Gödel, Tarski, Turing, etc. Surprisingly, the dialectic of mathematical logic from its inception (...) through the discovery of the diagonal theorems can be recognized as a particularly clear instance of the drama of reflection according to Sartre, especially in the positing and overcoming of its proper value-ideal, viz. the synthesis of consistency and completeness. Conversely, this translation solves a number of systematic problems about pure reflection’s relations to accessory reflection, phenomenological reflection, pre-reflective self-consciousness, conversion, and value. Negative foundations, the metaphysical position emerging from this translation between existential philosophy and metalogic, concurs by different paths with Badiou’s Being and Event in rejecting both ontotheological foundationalisms and constructivist antifoundationalisms.

Suetonius quotes at Tiberius 21. 4–7 a number of passages from letters of Augustus to Tiberius showing the high regard in which he professed to hold him, despite his reservations about the darker side of his character, once he had decided to adopt him ‘rei publicae causa’ in a.d 4. They seem to have attracted little critical comment, although Seager connects them with the handling by Tiberius of the Pannonian revolt in a.d. 6–9. suggesting that in view of their fulsome (...) character they were probably written towards the end of this period, when the crisis was past, rather than earlier when Augustus may have been critical of Tiberius’ caution in prosecuting the war. But he does not attempt a more detailed appraisal of the possible dates of the individual letters quoted. Sections 21. 4 and 5 in particular present interesting textual difficulties, mainly arising from the transmission of Greek in a predominantly Latin text: this article discusses these with a view to throwing greater light on the historical significance of the letters. First, the text, to which I have appended a limited apparatus which concentrates on the points of greatest difficulty. (shrink)

The foregoing, both appearing in early 2012, represent very different understandings about the significance of being substantially overweight and possible responses. The first focuses on being fat as the problem. 3 The solution is weight loss or, better still, prevention of weight gain. Of particular note is the plight of obese children and their physical ailments and psychological stress because of bullying by other children and embarrassment in wider society. The second underscores the enormous difficulty of losing weight and, (...) even more so, of maintaining any such reduction. Being fat may give rise to problems. But the greatest difficulty may be in not accepting that most people who become fat will remain fat. That denial stymies efforts to foster the healthiest state possible for the obese and to create effective prevention programs, especially for children. (shrink)

In Practice in Christianity, Kierkegaard claims that the imaginative planning of projects that require ongoing effort over time always fails to represent them accurately. This paper explores one particular reason Kierkegaard gives for thinking this—that the imagination is incapable of capturing the temporality of such endeavors, and it is this temporality that constitutes their greatest difficulty. This is significant for Kierkegaard because he believes that the tasks of the moral life and the religious life belong to this class (...) of endeavors. But if true, his claim raises questions for all self-determinative projects that use imaginative planning. -/- This paper explores Kierkegaard’s texts on the matter and argues that his claim centers on the fact that in one’s imagination, one cannot face ongoing resistance that is entirely outside one’s control as one does in the actual world. This contributes to a picture of Kierkegaard’s moral psychology that presents having a powerful imagination alone as quite insufficient for practical striving, and that places practice and willful endurance in whatever task one is attempting as central to learning it. One cannot learn how to do such tasks from another or from one’s imagination, according to Kierkegaard—the only teacher is experience, and, crucially, time. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Social Epistemologists at the Crossroads:Authorizing Agents of ChangeJames H. CollierIn this issue of Philosophy and Rhetoric, Thomas Basbøll and Christine Isager and Sine Just provide a vital, constructive forum for discussing the first and second editions of Philosophy, Rhetoric, and the End of Knowledge (PREK) and Steve Fuller's broader project of social epistemology. More specifically, both Basbøll's review and Isager and Just's suggest innovative proposals for applying and assessing (...) PREK's ideas and influence. In response, I analyze and counter Basbøll's and Isager and Just's conceptions of how agency is configured, and how criticism is authorized, at the level of textuality. I end by calling for deliberations to sort out what we, as social epistemologists and critical intellectuals, know and what we want to do about it.A Job for Social EpistemologistsIf the reader of PREK wants to "be" a social epistemologist, or "do" social epistemology, what would the job and its duties entail? Thomas Basbøll offers a job description for the social epistemologist as a "postmodern grammarian"—one "who corrects academic texts to suit them for strange times." This description strikes the dissonant chord of being at once pragmatic and abstract. On the one hand, correcting academic texts is a specific task reminiscent of the duties of writing instructors or editors. On the other hand, the specificity of the labor stands in juxtaposition to the surreal working conditions—the "strange times." And in the end, "postmodern grammarian" is hardly a position for which one could apply. Yet the specificity and dissonance in Basbøll's description reveals the difficulty and ambiguity of what Fuller asks the reader to do in PREK. Basbøll gets at this problem by [End Page 269] shifting the subject position of the social epistemologist to the postmodern grammarian. This move is necessary to bring social epistemology down from "the highest level" and make it task oriented. Interestingly, the job that Basbøll describes offers a return to textuality and, I would argue, critical intellectualism. Yet these positions appear somewhat removed from the role of the rhetorician as portrayed in PREK.In proposing a specific job for the social epistemologist, Basbøll develops a microlevel application of Fuller's macrolevel vision. Basbøll's task is not easy: "One of the greatest difficulties encountered in reading PREK is its willingness to make a great many philosophical commitments for openly rhetorical purposes. Not the least of these is the concept of knowledge that a research program and policy platform that calls itself 'social epistemology' is obviously dutybound to provide." The willingness of social epistemologists to occupy many philosophical positions also obscures what labor and service commitments they might make. Moreover, since PREK's initial publication (1993) Fuller has continued to multiply social epistemologists' roles regarding scientific conduct (Science, 1997; The Governance of Science, 2000a; Knowledge Management Foundations, 2002). Further, these commitments shift as Fuller has continued to reinterpret the historical record and to recast philosophical debates (Thomas Kuhn, 2000b; Kuhn vs. Popper, 2003). The ability to both destabilize and maintain such a fluid intellectual environment is something only Fuller, or the postmodern grammarian, could—or would want to—accomplish. More on that idea in a moment.Despite the moving target, defining the subject position of the social epistemologist has been a parallel conversation accompanying much of Fuller's work. I proposed the less "stylish" idea of the social epistemologist as technical communicator in PREK's first edition and in Scientific and Technical Communication (1997). Contemplating the social epistemologist's position as rhetorician, or vice versa, has been taken on by Keith (1995; 1996), Zagacki (1995), and Campbell and Benson (1996) (as summarized by Isager and Just). In contrast to these previous configurations, Basbøll situates the labor of the social epistemologist on the level of reading and writing. As he puts it:And it is precisely because the social epistemologist assists the writer of academic texts in the difficult task of connecting utterances to particular conditions (under which they are read) that social epistemology becomes a critical force. It is not by reconfiguring the knowledge-producing practices themselves [End Page 270] that this... (shrink)

Psychology has a long past, yet its real history is short. For thousands of years it has existed and has been growing older; but in the earlier part of this period it cannot boast of any continuous progress toward a riper and richer development. In the fourth century before our era that giant thinker, Aristotle, built it up into an edifice comparing very favorably with any other science of that time. But this edifice stood without undergoing any noteworthy changes or (...) extensions, well into the eighteenth or even the nineteenth century. Only in recent times do we find an advance, at first slow but later increasing in rapidity, in the development of psychology. The general causes which checked the progress of this science and thus made it fall behind the others can readily be stated:— "The boundaries of the Soul you cannot find, though you pace off all its streets, so deep a foundation has it," runs a sentence of Heraclitus, and it hits the truth more fully than its author could ever have expected. The structures and functions of our mental life present the greatest difficulties to scientific investigation, greater even than those presented by the phenomena, in many respects{4} similar, of the bodily life of the higher organisms. These structures and processes change so unceasingly, are so fleeting, so enormously complex, and dependent on so many factors hidden yet undoubtedly influential, that it is difficult even to seize upon them and describe their true substance, still more difficult to gain an insight into their causal connections and to understand their significance. We are just now beginning to recognize the full force of these difficulties. (shrink)

The objectives of this book are to provide a new translation of Plato's M eno together with a series of studies on its philcisophical argument in the light of recent secondary literature. My translation is based mainly on the Oxford Classical Text, 1. Burnet's Platonis Opera (Oxford Clarendon Press 1900) Vol. III. In conjunction with this I have made extensive use of R.S. Bluck's Plato's Meno (Cam bridge University Press, 1964). At critical places in the dialogue I have also consulted (...) A. Croiset's Gorgias, Menon (Bude text). My debt ~o two other sources will be clearly in evidence. They are E.S. Thompson's Plato's Meno (London, MacMillan 1901), and St. George Stock's The Meno of Plato (Oxford Clarendon Press, 1894). One of the greatest difficulties facing a translator is to achieve a balance between accuracy and elegance. Literal translations are more likely to be accurate, but, alas, they also tend to be duller. Free translations run into the opposite danger of paying for elegance and liveliness with the coin of inaccuracy. Another hurdle, for a translator of a Platonic dialogue, is posed by the challenge to maintain the conversational pattern and fast moving character of the discussion. This is easier where the exchang~s are short, but much more difficult where Socrates gets somewhat long-winded. (shrink)

When it comes to climate change, the greatest difficulty we face is that we do not know the likely degree of change or its cost, which means that environmental policy decisions have to be made under uncertainty. This book offers an accessible philosophical treatment of the broad range of ethical and policy challenges posed by climate change uncertainty. Drawing on both the philosophy of science and ethics, Martin Bunzl shows how tackling climate change revolves around weighing up our (...) interests now against those of future generations, which requires that we examine our assumptions about the value of present costs versus future benefits. In an engaging, conversational style, Bunzl looks at questions such as our responsibility towards non-human life, the interests of the developing and developed worlds, and how the circumstances of poverty shape the perception of risk, ultimate developing and defending a view of humanity and its place in the world that makes sense of our duty to Nature without treating it as a rights bearer. This book will be of interest to students and scholars of environmental studies, philosophy, politics and sociology as well as policy makers. (shrink)

Lower limb major amputations are both life-saving procedures and life-changing events. Individual responses to limb loss are varied and complex, some individuals experience functional, psychological and social dysfunction, many others adjust and function well. Some patients refuse amputation for religious and/or cultural reasons. One of the greatest difficulties for a person undergoing amputation surgery is overcoming the psychological stigma that society associates with the loss of a limb. Persons who have undergone amputations are often viewed as incomplete individuals. The (...) medical and physical consequences of amputation serve as the centerpiece in acute care and are commonly at the forefront of prosthetic rehabilitation. Prosthetic prescription aims to compensate for functional and/or cosmetic losses where possible. The aims of rehabilitation following amputation are to restore acceptable levels of functioning that allow individuals to achieve their goals, to facilitate personal health, and to improve participation in society and quality of life either with or without prosthesis. Our article aims at underscoring some medical, social and religious aspects that can contribute to the wellbeing of patients who suffer a life changing event such as lower limb amputation. (shrink)

This article presents an analysis of research results on two categories of workers and job candidates - the youngest and the oldest. These age group cohorts are under the greatest pressure in the Russian labour market: the greatest difficulties in getting a job, age discrimination, etc. Paradoxically, these groups show not a difference but rather a similarity in their value orientations. They often experience latent and obvious discrimination from HR managers. As a result, in many respects these groups (...) tend to have similar views about the labour market and their "life chances" to build a career and maintain income stability. The younger and older age groups are ready to interact with each other, but stereotypes about old age make this process difficult. State policies that support certain age groups in the labour market often intensify intergenerational conflicts rather than hinder them. The Corona Virus pandemic has significantly affected the position of the youngest and oldest people in the labour market, putting them in a situation where they cannot apply for good jobs and have to accept any work.

In Parmenides, the young Socrates defends several candidate forms against Parmenides, who makes five objections: the objection of forms of common things, the question of the part vs. the whole, the third man argument, infinite regress, and the greatest difficulty problem.

Since the exultant reception of Levinas’ work, particularly in the United States, an imposing obstacle to this oeuvre has steadily been erected.

On the contrary, the greatest difficulty today is the ease with which Levinas is arrogated, a (...) facility that risks making him so accessible as to be wholly irrelevant. The ubiquity in contemporary intellectual circles of an “ethics of the other” leads, from ever diverse paths, directly to Levinas; and it is just this that prevents us from reading him well.

`Europe' and national identity are not necessarily in conflict, as the examples of Spain, Greece, Germany and Italy in their different ways suggest.

1. The difference between the mathematical and the intuitive mind.- In the one, the principles are palpable, but removed from ordinary use; so that for want of habit it is difficult to turn one's mind in that direction: but if one turns it thither ever so little, one sees the principles fully, and one must have a quite inaccurate mind who reasons wrongly from principles so plain that it is almost impossible they should escape notice. But in the intuitive mind (...) the principles are found in common use and are before the eyes of everybody. One has only to look, and no effort is necessary; it is only a question of good eyesight, but it must be good, for the principles are so subtle and so numerous that it is almost impossible but that some escape notice. Now the omission of one principle leads to error; thus one must have very clear sight to see all the principles and, in the next place, an accurate mind not to draw false deductions from known principles. All mathematicians would then be intuitive if they had clear sight, for they do not reason incorrectly from principles known to them; and intuitive minds would be mathematical if they could turn their eyes to the principles of mathematics to which they are unused. The reason, therefore, that some intuitive minds are not mathematical is that they cannot at all turn their attention to the principles of mathematics. But the reason that mathematicians are not intuitive is that they do not see what is before them, and that, accustomed to the exact and plain principles of mathematics, and not reasoning till they have well inspected and arranged their principles, they are lost in matters of intuition where the principles do not allow of such arrangement. They are scarcely seen; they are felt rather than seen; there is the greatest difficulty in making them felt by those who do not of themselves perceive them. These principles are so fine and so numerous that a very delicate and very clear sense is needed to perceive them, and to judge rightly and justly when they are perceived, without for the most part being able to demonstrate them in order as in mathematics, because the principles are not known to us in the same way, and because it would be an endless matter to undertake it.

This article seeks to overcome some of the greatest difficulties in generating a feminist-friendly approach to sacraments by proposing a new paradigm: sacraments as forms of energy. Several factors have hindered feminist theologians in revisioning sacramentality. For the most part sacraments were ‘done to’ women, never ‘done by’ women. A too-literal reading of the Christian scriptures blurs the fact that early Christians developed ritual patterns for Baptism and Eucharist first, and only later wrote them down. To speak of sacraments (...) as mediations may re-inscribe dualism. The static model of reality which explained sacraments in Aristotelian categories of matter and form has given way to dynamic models of matter and energy. A sacramentality of energy can be articulated from three different angles: first, in terms of the action of the Holy Spirit; second, from scientific advances in quantum thinking, and the third from new spirituality. This paradigm applies to both Baptism and Eucharist. (shrink)

Objectives The objectives of the study are to understand the current practice of informed consent in medical research in public hospitals in Shanghai, and to share our views with other countries, especially developing countries. Methods In the study, 145 consent forms (CFs) of the selected research projects in eight public hospitals with ethics committees in Shanghai were audited, and the principle investigators (PIs) of these research projects and 40 student subjects who had participated in clinical drug tests were surveyed by (...) questionnaires. Results The CFs of medical researches in public hospitals with ethics committees in Shanghai were generally acceptable. However, there were some defects in the CFs. Although most of the surveyed PIs had correct recognition of informed consent, some processes of informed consent were not in accordance with generally accepted requirements. A large number of the PIs considered the greatest difficulty with informal consent was lack of correct recognition of subjects or legally authorised representatives on medical research. Discussion Informed consent in medical research should consider the research ethics, the background of potential subjects, the local resources and culture of medical research. In addition, special protection is needed for student subjects in informed consent as well as efforts for building and restoring the public's trust in biomedical research. Conclusion The informed consent in Shanghai's public hospitals with ethics committees was generally acceptable and the achievement of adequate informed consent is influenced by many factors.

This book deals with the epicenter of modern philosophy, Kant's transcendental thinking self. It lives and breathes not only in the unity of reason in Kant himself, but also spells out how the problems that emerge in that conception were dealt with in the intellectual world of early German idealism. Bondeli shows how Kant's unity of reason is variously conceived by Kant as the "I think," the "highest point" of the "unity of apperception," as well as the more traditional concept (...) of "soul," which is freighted with heavy metaphysical baggage. According to Bondeli, Kant had the greatest difficulty providing adequate reasons for that unity of apperception. Those difficulties are laid bare in part A of the first part of the book, "Kant's Problem of an Adequate Founding of the Original-Synthetic Unity of Apperception." The problem Bondeli lays bare provided ample fodder for Kant's critics, first and foremost the very early pre-Kantian Carl Leonhard Reinhold, soon, however, to emerge as the "Kantian of the first hour" in his Kantian Letters, but then also for Maimon, Schulze, Beck, and Fichte. Bondeli deals with the criticisms of those important thinkers in part B, "Reactions to Kant's Problem.". (shrink)

The per se beings are those signified by the ultimate predicates in species–genus hierarchies: what a thing is, quality, quantity, relation, and so forth. Understanding change requires the investigation of the potential versus actual existence of any such per se being. Yu argues that Aristotle’s references in his central text on the focal structure of being to process, generation, and destruction imply that substance is the focus not only of the other per se beings but also of potential versus actual (...) being. But, he holds, for different reasons, that the other per se beings depend on substance, whereas change in the category of substance raises the greatest difficulties for Parmenides’s argument against generation.

Undeniably, the greatest way for a Moslem to be closer to Allah, is recitation of Holy-Quran approves with the method conveyed from Messenger of Allah Mohammed from the feature of speech points of letters and the intrinsic and fleeting characteristics of the letters, So, there is a persistent need to teach all Moslems the science of Tajweed Al-Quran. ITS (Intelligent Tutoring System) is computer software that supplies direct and tailored training or response to students without human teacher interfering. The (...) main target of ITS is smoothing the learning process using the wide-ranging facilities of computer. The proposed system will be implemented using the ITSB Authoring tool. In this thesis, the researcher presents an intelligent tutoring system for teaching Reciting Al-Quran "Tajweed" with Rewaya: Hafs from ‘Aasem by the way of Shatebiyyah. It was a novel idea that the researcher combined the science of Tajweed Al-Quran and the science of artificial intelligence in his thesis. The researcher arranged the material into chapters, lessons, examples then, added all these to the proposed system. He also added questions, right answers and the level of difficulty for each lesson. He prepared an exam for each chapter and a final exam to test the knowledge of the learner in the whole material. The system was evaluated by teachers and students in reciting science and the outcome of the assessment was encouraging and promising. (shrink)

Observers have difficulty detecting visual changes. However, they are unaware of this inability, suggesting that people do not have an accurate understanding of visual processes. We explored whether this error is related to participants’ beliefs about the roles of intention and scene complexity in detecting changes. In Experiment 1 participants had a higher failure rate for detecting changes in an incidental change detection task than an intentional change detection task. This effect of intention was greatest for complex scenes. (...) However, participants predicted equal levels of change detection for both types of changes across scene complexity. In Experiment 2, emphasizing the differences between intentional and incidental tasks allowed participants to make predictions that were less inaccurate. In Experiment 3, using more sensitive measures and accounting for individual differences did not further improve predictions. These findings suggest that adults do not fully understand the role of intention and scene complexity in change detection. (shrink)

Aristotle is one of the very greatest thinkers in the Western tradition, but also one of the most difficult. The contributors to this volume do not attempt to disguise the nature of that difficulty, but at the same time they offer a clear exposition of the central philosophical concerns in his work. Approaches and methods vary and the volume editor has not imposed any single interpretation, but has rather allowed legitimate differences of interpretation to stand. An introductory chapter (...) provides an account of Aristotle's life, and then guides the reader through the complex subject of what Aristotle actually wrote as a basis for characterising his philosophical development. Subsequent chapters cover Aristotle's writings on logic, metaphysics, science, psychology, ethics, politics, rhetoric, and poetics. It is a basic assumption of the Companion that its readers will not know Greek. (shrink)

Consciousness is arguably the greatest mystery in science, still being unsolved after millennia of thinking. This book is one further attempt at trying to bring new insights regarding consciousness. While certainly the mystery will continue, the ideas in this book will raise awareness regarding an aspect of the phenomenology of consciousness that has been overlooked by past thinkers, and that is the emergent structure of consciousness, which in the end will be shown to be realized by the nature of (...) self-reference of looking-back-at-itself. The great take-away from appreciating the true nature of self-refence would be the need to switch to an unformal way of thinking in doing science if the problem of consciousness is to be resolved. To unformal way of thinking means abandoning the desire to have clearly defined entities in our theories, like “energy” or “space-time” or “spin”, and instead allow for entities that cannot be formalized, to be responsible for the workings of the world. We will slowly see as the book unfolds why the need for unformal way of thinking arises. -/- Regarding the presentation style, the book is both a popular book and a rigorous presentation that goes into thorough phenomenological analyses of consciousness. The reason is that our lives themselves are both familiar and the very nature of existence. As opposed to other writings that use a more technical approach, the philosophy of this book is that a theory of consciousness should focus more on the most mundane manifestations of consciousness, like the redness of an apple or the warmish feeling of cup of hot chocolate, in order to give a clearer understanding of consciousness. Therefore, the book is full of everyday examples of conscious experiences that the reader can relate to and use them to gain deeper insights into the workings of consciousness. In the same way that LHC is the laboratory of physicists, introspection is our own laboratory, the advantage of introspection over LHC being that it is accessible to anyone. Every person can gain a deep knowledge of consciousness by simply paying close attention to his own experiences. Of course, the difficulty arises because of the huge diversity of our experiences and this might raise an apparent initial obstacle of where one is to begin his understanding of consciousness. The book is designed as a guide through the complexities of everyday experiences in the direction of sorting them out in general and clear ways of thinking, showing that consciousness needs not be something that difficult to understand if only the proper attention is given to our experiences. -/- Therefore, the book starts with a chapter about qualia, where through many examples it is shown to be a form of meaning. Then the reader is familiarized with the Self through simple thought experiments that lead to the conclusion of the unicity of the Self, and then a further logical analysis that shows the eternal existence of the Self. After these initial familiarizations with consciousness, the book goes into its core subject, that being the emergent phenomenology, in which it will be shown how consciousness is structured on a holarchy of levels and how ultimately this structuring is a result of self-reference looking-back-at-itself, consciousness being shown to be possible only because of the unformalizable nature of self-reference.

'any service I may have rendered my countrymen in my active life I may also extend to them... now that I am at leisure'Marcus Tullius Cicero, Rome's greatest orator, had a career of intense activity in politics, the law courts and the administration, mostly in Rome. His fortunes, however, followed those of Rome, and he found himself driven into exile in 58 BC, only to return a year later to a city paralyzed by the domination of Pompey, Crassus, and (...) Caesar. Cicero, though a senior statesman, struggled to maintain his independence and it was during these years that, frustrated in public life, he first started to put his excess energy, stylistic brilliance, and superabundant vocabulary into writing these works of philosophy. The three dialogues collected here are the most accessible of Cicero's works, written to his friends Atticus and Brutus, with the intent of popularizing philosophy in Ancient Rome. They deal with the everyday problems of life; ethics in business, the experience of grief, and the difficulties of old age. (shrink)

""This book contains a careful, thorough, and where necessary skeptical as regards doubtful evidence (especially in the case of Plato and the Old Academy) of the beginnings in European thought of the negative or apophatic way of thinking and its relations to more positive or kataphatic ways of thinking about God. One of its greatest strengths, perhaps the greatest, is that the author makes clear that none of the persons concerned, Hellenic, Jewish or Christian, was engaged in the (...) pursuit of a philosophical abstraction, or the heaping of rhetorical superlatives on God. They were rather concerned to present the origin of the universe as an intimately present living reality which infinitely transcends our thought and speech. This, combined with careful attention to the varieties of negative theology and its relations with positive, and the particular difficulties experienced by the members of the various traditions involved, makes the book the best introduction to the negative theology available."" -A.

JOURNAL OF THE HISTORY OF PHILOSOPHY PRIZE for the best published book in the history of philosophy [Awarded in 2010] _______________ -/- Although it is widely recognized that David Hume's A Treatise of Human Nature (1739-40) belongs among the greatest works of philosophy, there is little agreement about the correct way to interpret his fundamental intentions. It is an established orthodoxy among almost all commentators that skepticism and naturalism are the two dominant themes in this work. The difficulty (...) has been, however, that Hume's skeptical arguments and commitments appear to undermine and discredit his naturalistic ambition to contribute to "the science of man". This schism appears to leave his entire project broken-backed. The solution to this riddle depends on challenging another, closely related, point of orthodoxy: namely, that before Hume published the Treatise he removed almost all material concerned with problems of religion. Russell argues, contrary to this view, that irreligious aims and objectives are fundamental to the Treatise and account for its underlying unity and coherence. It is Hume's basic anti-Christian aims and objectives that serve to shape and direct both his skeptical and naturalistic commitments. When Hume's arguments are viewed from this perspective we can solve, not only puzzles arising from his discussion of various specific issues, we can also explain the intimate and intricate connections that hold his entire project together. This "irreligious" interpretation provides a comprehensive fresh account of the nature of Hume's fundamental aims and ambitions in the Treatise. It also presents a radically different picture of the way in which Hume's project was rooted in the debates and controversies of his own time, placing the Treatise in an irreligious or anti-Chrisitan philosophical tradition that includes Hobbes, Spinoza and freethinking followers. Considered in these terms, Hume's Treatise constitutes the crowning achievement of the Radical Enlightenment. (shrink)

The Oxford Philosophical Texts series consists of authoritative teaching editions of canonical texts in the history of philosophy from the ancient world down to modern times. Each volume provides a clear, well laid out text together with a comprehensive introduction by a leading specialist,giving the student detailed critical guidance on the intellectual context of the work and the structure and philosophical importance of the main arguments. Endnotes are supplied which provide further commentary on the arguments and explain unfamiliar references and (...) terminology, and a fullbibliography and index are also included.The series aims to build up a definitive corpus of key texts in the Western philosophical tradition, which will form a reliable and enduring resource for students and teachers alike.In his Principles of Human Knowledge Berkeley makes the striking claim that physical things consist of nothing but ideas, and so do not exist outside the mind. This establishes Berkeley as the founder of the idealist tradition in philosophy. Berkeley argues vigorously that once we correct ourunderstanding of the physical, we can find a new proof of the existence of God, refute sceptical attacks on human knowledge, and resolve many difficulties and paradoxes raised by the advance of science.The text printed in this volume is the 1734 edition of the Principles which is generally agreed to represent Berkeley's mature thought. Also included are the four important letters between George Berkeley and Samuel Johnson, written in 1729-30. The text is supplemented by a comprehensiveintroduction which looks at the structure and main arguments of the text, as well as discussing Berkeley's life, influences, and general philosophy. In addition the volume includes an analysis of the text, a glossary, detailed notes, and a full bibliography with guidance on further reading.This new edition of Berkeley's most famous work, published alongside his other masterpiece, the Three Dialogues (also edited by Jonathan Dancy) provides the student with a thorough introduction to the central ideas of one of the world's greatest philosophers.

-- Immanuel Kant (Kant 1990, p. 46/429) The idea that our most basic duty is to treat each other with respect is one of the Enlightenment’s greatest legacies and Kant is often thought to be one of its most powerful defenders. If Kant’s project were successful then the lofty notion that humanity is always worthy of respect would be vindicated by pure practical reason. Further, this way of defending the ideal is supposed to reflect our autonomy, insofar as it (...) is always one’s own reason that demands that one treat humanity with respect. In this article, I consider what I take to be one of the most important and compelling attempts to defend the Kantian project. I draw the disappointing conclusion that this attempt does not succeed. The reasons this attempt fails shed some light on the difficulties facing any attempt to defend the Kantian project. (shrink)

To raise the question of the nature of narrative is to invite reflection on the very nature of culture and, possibly, even on the nature of humanity itself. So natural is the impulse to narrate, so inevitable is the form of narrative for any report of the way things really happened, that narrativity could appear problematical only in a culture in which it was absent—absent or, as in some domains of Western intellectual and artistic culture, programmatically refused. As a panglobal (...) fact of culture, narrative and narration are less problems than simply data. As the late Roland Barthes remarked, narrative "is simply there like life itself . . . international, transhistorical, transcultural."1 Far from being a problem, then, narrative might well be considered a solution to a problem of general human concern, namely, the problem of how to translate knowing into telling,2 the problem of fashioning human experience into a form assimilable to structures of meaning that are generally human rather than culture-specific. We may not be able fully to comprehend specific thought patterns of another culture, but we have relatively less difficulty understanding a story coming from another culture, however exotic that culture may appear to us. As Barthes says, "narrative...is translatable without fundamental damage" in a way that a lyric poem or a philosophical discourse is not. · 1.

1. Introduction. In a famous passage near the beginning of A Theory of Justice, John Rawls discusses utilitarianism’s notorious difficulties with justice. According to classic forms of utilitarianism, a certain course of action is morally right if it produces the greatest sum of satisfactions. And, as Rawls points out, the perplexing implication is “…that it does not matter, except indirectly, how this sum of satisfactions is distributed among individuals any more than it matters, except indirectly, how one man distributes (...) his satisfactions over time.” He concludes the passage by saying that “[u]tilitarianism does not take seriously the distinction between persons.”.

Due to the importance of both freedom and law this might be considered Arendt’s greatest puzzle.

This paper aims to address this (...) gap. (shrink)

I Shall begin by a distinction which will limit my subject. I propose to speak only of beautiful poetry and beautiful prose, or if the phrase be preferred, artistic poetry and prose. The distinction I wish to draw is between art and craft, between making a competent and useful thing which exactly fits its purpose and making it beautifully, between technical skill and artistry, between good workmanship and design and that touch of rareness which makes not merely good but fine (...) and lovely. The boundaries are difficult to draw. For much craft is also beautiful, and the craftsman is always in doing his best, striving to be an artist and often succeeding. But they are not the same things. Mere technical skill will not make a work beautiful but only correct, and on the other hand art may possess beauty, even if not of the highest order; though it fails in skill, the conception in some degree makes up for the defect of skill, as for instance much primitive Italian painting or Greek sculpture, which is defective in drawing or modelling and yet beautiful. Now a large part, perhaps the greater part, of what is called art is not art at all, but craft, good correct painting or drawing or sculpture; pleasing, but not pleasing with the pleasure or even rapture which beauty gives. It is so with prose and poetry. Many poems are not poetry, though written in impeccable verse, and long poems are always apt to drop in places into what is only not called prose because it is metrical. By far the greatest part of prose is merely good workmanlike writing, and in no sense art. I am not intending to depreciate craft, and still less the value and difficulty of attaining it. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 34.3 (2001) 245-259 [Access article in PDF] Virtue in Aristotle's Rhetoric: A Metaphysical and Ethical Capacity Susan K. Allard-Nelson It has been argued that Aristotle's description of excellence (aretê) as a capacity (dynamis) in Rhetoric 1.9 is inconsistent with his treatment of excellence in Nicomachean Ethics 2.5, where he specifically argues that aretê is not a dynamis, but a hexis (i.e., a state or condition). 1 (...) Certainly, the word that Aristotle uses throughout the Nicomachean Ethics to both describe and categorize aretê is hexis, and he uses this word at Rhetoric 1.6.1362b13, where he says that several of the virtues, and all other such states (kai hai allai hai toiautai hexeis), are excellences of the soul. However, as part of his discussion of the ethical aspects of oratory, Aristotle states that aretê is "a capacity (dynamis) of providing and preserving good things, and a capacity of conferring many great benefits (euergetikê)" (Rh. 1.9.1366a36-1366b1). 2 This discussion is set in language similar to that used to discuss excellence and goodness in Rhetoric 1362b2-4 and 1361a28-30; this suggests that Aristotle intentionally identifies aretê with dynamis in this text, and, to some degree at least, with the dynamis to benefit others. In the former passage, Aristotle claims that "the excellences, too, must be a good thing, for those who possess them are in a good condition, and they are productive of good things and good actions" (Rh. 1.6.1362b2-4). In the latter passage, Aristotle states that honor (timê) can be paid, not only to those who have already done good, but also to those who have the capacity to do good (dynamenos euergetein) in the future. Indeed, in the Rhetoric 1.9.1366b3-7, Aristotle further unites the concepts of excellence, capacity, and beneficence by stating, "If excellence is the capacity of conferring benefits (dynamis euergetikê), then the greatest virtues must be those which are the most useful to others, and, for this reason, justice and courage are the most honored; for the latter is useful to others in war, and the former both in war and in peace" (1366b3-7). [End Page 245]Based on an understanding of this apparent inconsistency in terminology as intentional on Aristotle's part, I intend to argue here that Aristotle's identification of aretê with dynamis in Rhetoric can be understood within the highly specific context of rhetoric as an art as more appropriate, both metaphysically and ethically, than would have been an identification of aretê with hexis. I also intend to argue that, while certain tensions and difficulties are created by the classification of aretê as a dynamis in the Rhetoric and as a hexis in the Nicomachean Ethics, 3 Aristotle can be defended against the charge of inconsistency.To this end, then, I begin by examining the implications of defining rhetoric as an art (technê) that has persuasion (pistis) as its end (telos) and function (ergon). 1. Rhetoric is an art, and, as we know from EN 6.4, art is identical to a state of reasoned capacity to make, and all art is concerned with the coming into being of something that is capable of either being or not being, and whose origin is in the maker (1140a1-23). Art is a rational capacity, or a potency that moves according to, and involves, a rational formula (kai ta men kata logon dynatai kinein kai hai dynameis auton meta logou), and, as such, it is capable of producing contrary effects (Met. 9.5.1047b31-1048a24). For this reason, and to negate the impossibility of contrary effects being produced simultaneously, Aristotle states that a rational capacity involves not only the elements of agent and patient, but also a desire or choice on the part of the agent that moves her 4 to act (Met. 9.5.1048a10). This necessary desire or choice, in fact, explains why an inference in the case of the arts (or of any rational capacity) can be made in one direction... (shrink)

There are several conceptions of truth, such as the classical correspondence conception, the coherence conception and the pragmatic conception. The classical correspondence conception, or Aristotelian conception, received a mathematical treatment in the hands of Tarski (cf. Tarski [1935] and [1944]), which was the starting point of a great progress in logic and in mathematics. In effect, Tarski's semantic ideas, especially his semantic characterization of truth, have exerted a major influence on various disciplines, besides logic and mathematics; for instance, linguistics, the (...) philosophy of science, and the theory of knowledge. The importance of the Tarskian investigations derives, among other things, from the fact that they constitute a mathematical, formal mark to serve as a reference for the philosophical (informal) conceptions of truth. Today the philosopher knows that the classical conception can be developed and that it is free from paradoxes and other difficulties, if certain precautions are taken. We believe that is not an exaggeration if we assert that Tarski's theory should be considered as one of the greatest accomplishments of logic and mathematics of our time, an accomplishment which is also of extraordinary relevance to philosophy, as we have already remarked. In this paper we show that the pragmatic conception of truth, at least in one of its possible interpretations, has also a mathematical formulation, similar in spirit to that given by Tarski to the classical correspondence conception.
