Harmony Search Algorithm (HSA) is an evolutionary algorithm which mimics the process of music improvisation to obtain a nice harmony. The algorithm has been successfully applied to solve optimization problems in different domains. A significant shortcoming of the algorithm is inadequate exploitation when trying to solve complex problems. The algorithm relies on three operators for performing improvisation: memory consideration, pitch adjustment, and random consideration. In order to improve algorithm efficiency, we use roulette wheel and tournament selection in memory consideration, (...) replace the pitch adjustment and random consideration with a modified polynomial mutation, and enhance the obtained new harmony with a modified β-hill climbing algorithm. Such modification can help to maintain the diversity and enhance the convergence speed of the modified HS algorithm. β-hill climbing is a recently introduced local search algorithm that is able to effectively solve different optimization problems. β-hill climbing is utilized in the modified HS algorithm as a local search technique to improve the generated solution by HS. Two algorithms are proposed: the first one is called PHSβ–HC and the second one is called Imp. PHSβ–HC. The two algorithms are evaluated using 13 global optimization classical benchmark function with various ranges and complexities. The proposed algorithms are compared against five other HSA using the same test functions. Using Friedman test, the two proposed algorithms ranked 2nd (Imp. PHSβ–HC) and 3rd (PHSβ–HC). Furthermore, the two proposed algorithms are compared against four versions of particle swarm optimization (PSO). The results show that the proposed PHSβ–HC algorithm generates the best results for three test functions. In addition, the proposed Imp. PHSβ–HC algorithm is able to overcome the other algorithms for two test functions. Finally, the two proposed algorithms are compared with four variations of differential evolution (DE). The proposed PHSβ–HC algorithm produces the best results for three test functions, and the proposed Imp. PHSβ–HC algorithm outperforms the other algorithms for two test functions. In a nutshell, the two modified HSA are considered as an efficient extension to HSA which can be used to solve several optimization applications in the future. (shrink)

While refutation is usually related to Plato's early, Socratic, dialogues, this paper is aimed at exploring the link between refutation and dialectic in some of his middle and late dialogues. First, it argues that refutation assumes a constructive role in the Phaedo, where the best logos is the least refutable, and also in the Republic, where the philosopher is invited to fight his way through all elenchoi. Then, it tries to show that the gymnasia of Prm. 130a ff. (...) is aimed at training young Socrates to come to the aid of the theory he embraces preventing it from being refuted. He should travel and explore all the paths, by assuming a hypothesis as well as the opposite one. This methodology paves the way on which Plato advances in the Sophist, where the antinomic structure of the gymnasia gives way to a “constructive” dialectic in which the aporia is solved and a thesis is established by refutation. The last section of this paper is devoted to analysing Sph. 251c-252e, where the positive and constructive function of the elenchus is especially clear. Plato argues for the symploke eidon by exploring all the hypotheses that are open to the search and refuting those that ultimately represent obstacles to his position. The symploke is the truth which remains when all the hypotheses that contradict it have been refuted. The conclusion is that the elenchus does not disappear but is put at the service of the truth, as an essential part of the method for attaining a positive doctrine. (shrink)

The BankXX system models the process of perusing and gathering information for argument as a heuristic best-first search for relevant cases, theories, and other domain-specific information. As BankXX searches its heterogeneous and highly interconnected network of domain knowledge, information is incrementally analyzed and amalgamated into a dozen desirable ingredients for argument (called argument pieces), such as citations to cases, applications of legal theories, and references to prototypical factual scenarios. At the conclusion of the search, BankXX outputs (...) the set of argument pieces filled with harvested material relevant to the input problem situation.This research explores the appropriateness of the search paradigm as a framework for harvesting and mining information needed to make legal arguments. In this article, we describe how legal research fits the heuristic search framework and detail how this model is used in BankXX. We describe the BankXX program with emphasis on its representation of legal knowledge and legal argument. We describe the heuristic search mechanism and evaluation functions that drive the program. We give an extended example of the processing of BankXX on the facts of an actual legal case in BankXX's application domain — the good faith question of Chapter 13 personal bankruptcy law. We discuss closely related research on legal knowledge representation and retrieval and the use of search for case retrieval or tasks related to argument creation. Finally we review what we believe are the contributions of this research to the understanding of the diverse disciplines it addresses. (shrink)

In his major new book A.C. Grayling examines the different ways to live a good life, as proposed from classical antiquity to the recent present. Grayling focuses on the two very different conceptions of what a good life should be: one is a broadly secular view rooted in attitudes about human nature and the human condition; the other is a broadly transcendental view which locates the source of moral value outside the human realm. In the modern world - the world (...) shaped by the rise of science in the seventeenth century - these two views have come increasingly into conflict, and the constantly accumulating tension between them is one of the greatest problems faced by the twenty-first century. Using his renowned clarity of thought and philosophical rigour, AC Grayling has produced an invaluable guide through mankind's ethical struggle to live decently. (shrink)

Background Best interests is a ubiquitous principle in medical policy and practice, informing the treatment of both children and adults. Yet theory underlying the concept of best interests is unclear and rarely articulated. This paper examines bioethical literature for theoretical accounts of best interests to gain a better sense of the meanings and underlying philosophy that structure understandings. Methods A scoping review of was undertaken. Following a literature search, 57 sources were selected and analysed using the (...) thematic method. Results Three themes emerged. The first placed best interests within the structure of wider theory, noting relationships with consequentialism, deontology, prudential value theory, rights and political philosophy. The second mapped a typology of processes of decision-making, among which best interests was ambiguously positioned. It further indicated factors that informed best interests decision-making, primarily preferences, dignity and quality of life. The final theme considered best interests from a relational perspective. Conclusions Characterisation of best interests as strictly paternalist and consequentialist is questionable: while accounts often suggested a consequentialist basis for best interests, arguments appeared philosophically weak. Deontological accounts, found in law and Kantianism, and theories of political liberalism influenced accounts of best interests, with accounts often associating best interests with negative patient preferences (i.e. individual refusals). There was much more emphasis on negative interests than positive interests. Besides preference, factors like dignity and quality of life were held to inform best interests decisions, but generally were weakly defined. To the extent that preferences were unable to inform decision making, decisions were either made by proxy authority or by an intersubjective process of diffuse authority. Differing approaches reflect bifurcations in liberal philosophy between new liberalism and neo-liberalism. Although neither account of authority appears dominant, bias to negative interests suggests that bioethical debate tends to reflect the widespread ascendancy of neo-liberalism. This attitude was underscored by the way relational accounts converged on private familial authority. The visible connections to theory suggest that best interests is underpinned by socio-political trends that may set up frictions with practice. How practice negotiates these frictions remains a key question. (shrink)

I outline a dilemma for Derek Parfit’s project to vindicate moral realism. In On What Matters, Parfit argues that the best versions of three of the main moral traditions agree on a set of moral principles, which should make us more confident about the prospects of truth in ethics. I show that the result of this Convergence Argument can be interpreted in two ways. Either there remain three separate and deontically equivalent theories or there remains just one theory, the (...) Triple Theory. Both interpretations fail to deliver what Parfit is looking for. The first interpretation leads to a situation of underdetermination of theory choice that gives rise to a skeptical challenge. The second interpretation jettisons Parfit’s Conciliatory Project, that is, the reconciliation of the three moral traditions. The dilemma, I contend, is the result of Parfit failing to resolve two antithetical lines of thought. His search for the Trinity of moral theorizing must thus fail. (shrink)

PurposeTo investigate how search engine users manipulate the rankings of search results. Search engines employ different ranking methods in order to display the “best” results first. One of the ranking methods is PageRank, where the number of links pointing to the page influences its rank. The “anchor text,” the clickable text of the hypertext link is another “ingredient” in the ranking method. There are a number of cases where the public challenged the Google's ranking, by (...) creating a so‐called “Google bomb” – creating links to pages they wanted to be highly ranked for given query. Google is chosen as the search engine, because it is currently by far the most popular search engine.Design/methodology/approachPageRank, one of the major parameters of Google's ranking algorithm is described, and the author explains how this algorithm is exploited by communities of users to promote a certain web page for a specific query. This process is called “Google bombing.” Recent reaction of Google to this phenomenon is also described.FindingsSpecific examples of “accomplished Google bombs” show that the public is able to manipulate search results.Originality/valueGoogle, instead of being an unobtrusive information retrieval tool has become highly influential in the web scenery. Some users pay for search engine optimization, while others utilize the power of the crowd to influence Google's rankings. This paper supports the claims of Introna and Nissenbaum regarding the power of search engines. (shrink)

Though researchers working on congenital aphantasia (henceforth “aphantasia”) agree that this condition involves an impairment in the ability to voluntarily generate visual imagery, disagreement looms large as to which other impairments are exhibited by aphantasic subjects. This article offers the first extensive review of studies on aphantasia, and proposes that aphantasic subjects exhibit a cluster of impairments. It puts forward a novel cognitive theory of aphantasia, building on the constructive episodic simulation hypothesis of memory and imagination. It argues that (...) aphantasia is best explained as a malfunction of processes in the episodic system, and is therefore an episodic system condition. (shrink)

This book studies creativity in its own right in the search for a creativity science. If we assume that creativity can best be described by constraint theory, the complexity and paradoxes of creativity can be reduced by dividing it into manageable sections. The model is tested and evidenced by numerous historical cases of pioneering work within the three intellectual fields: science, art, and technology. The model guides non-specialists from the many disciplines studying creativity and demonstrates the first (...) principles of creativity science. Going all the way back to Aristotle, the author makes the basic ideas of the original founder of creativity science accessible and up to date with current research. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Searching for a Universal Ethic: Multidisciplinary, Ecumenical, and Interfaith Responses to the Catholic Natural Law Tradition ed. by John Berkman and William C. Mattison IIIStewart D. ClemSearching for a Universal Ethic: Multidisciplinary, Ecumenical, and Interfaith Responses to the Catholic Natural Law Tradition Edited by John Berkman and William C. Mattison III GRAND RAPIDS, MI: EERDMANS, 2014. 339 PP. $35.00Despite its generalist title, this book is the result of (...) a very specific and multilayered textual history. The core of the volume is the official English translation of the International Theological Commission (ITC) document In Search of a Universal Ethic: A New Look at the Natural Law, which alone composes nearly a quarter of the book's text. Following five years of work, the commission first published the document in 2009. The following year, a special session at the annual meeting of the Society of Christian Ethics was convened for the purpose of discussing the document, and this session served as the impetus for the present volume. Along with Berkman and Mattison's introductory chapter, the remainder of the book is composed of responses to the document from no less than twenty-two scholars representing a broad range of religious and philosophical commitments.If there is anything approaching a consensus among the volume's diverse respondents, it is a nearly unanimous verdict that the ITC document offers a more winsome portrayal of natural law theorizing than anything that has been promulgated in official Church documents during the last several decades. As Serge-Thomas Bonino, OP (one of the document's coauthors), explains, the commission endeavored to situate the doctrine of natural law within "a larger theological framework that is both Christological and Trinitarian" (98). Many respondents praise the document's more nuanced and open-ended analysis of the natural law—one that accommodates a wide variety of sociocultural contexts—as well as the document's clarity and boldness in articulating a Christian (and specifically Christological) interpretation of the natural law tradition.The high level of admiration bestowed on the document does not mean that it is without its detractors, however. Some of the more critical respondents maintain that, in spite of the commission's "new look" at the natural law, many of the classical objections to the doctrine still hold. Gilbert Meilaender, for example, lauds the document's Christological commitments but worries that it fails to explain how this facet of the Catholic natural law tradition can help us to develop a universal ethic on which all can agree (226). Others express doubts precisely about what is "new" in this new look at the natural law. This [End Page 202] is perhaps best reflected by Jennifer Herdt's remark that "the note of epistemological modesty repeatedly sounded by In Search of a Universal Ethic seems to ring hollow" (210). In other words, the move toward less specificity regarding moral norms may in fact render the natural law inadequate as a framework for dialogue across cultures.Given the perennial subject matter of this volume, the editors have done an excellent job of balancing a vast range of perspectives and approaches to the natural law, rendering it useful to a wide audience. The sheer number of authors could easily have resulted in a collection that reflected breadth at the expense of depth. Thankfully, however, the presence of the ITC text as the locus of discussion helps to ground the conversation in such a way that all of the authors are fruitfully engaging the same set of questions. For this reason, it is among the best volumes currently available for those who wish to engage the most creative and rigorous thinking within the natural law tradition.Stewart D.

Mahāyāna ethics has a threefold emphasis: avoiding all evil, cultivating good, and saving all beings. Most Western studies of Buddhist ethics have used Pali and Sanskrit sources to examine the first two components, which are based on monastic codes for avoiding wrong doing and attain- ing virtue. Among the few studies of the third category, which includes Buddhist social ethics, East Asian Mahāyāna materials have been sadly lacking despite the Mahāyāna rhetoric about saving all beings. To correct this deficiency, (...) this paper analyzes an early lay Mahayana text, the Updsaka Precept Sūtra. The Upāsaka differs from earlier Buddhism and from many other Mahāyāna texts in two ways: it gives supremacy to com- passionate action in society rather than monastic spiritual attainment, and it asserts that helping others out of compassion is the highest practice and best way to attain enlightenment.

It would be difficult to find a more perceptive description of Western man and the world he now inhabits than that provided by Chantal Delsol in Icarus Fallen: The Search for Meaning in an Uncertain World . With style and lucidity, Delsol likens contemporary Western man to the mythical figure Icarus, fallen back to earth after trying to reach the sun, alive but badly shaken and confused. During the twentieth century, Delsol argues, man flew too closely to the sun (...) of utopian ideology. Having been burned, he is now groping for a way to orient himself. But the ideas he once held so dear--inevitable progress, the possibility of limitless social and self-transformation--are no longer believable, and he has, for the most part, long since rejected the religious tradition that might now have provided an anchor. Delsol's portrait is engrossing. She explains how we have come simultaneously to embrace the "good" but reject the "true"; how we have sacralized rights and democracy; and how we have lost our sense of the tragic and embraced the idea of "zero risk." Already a well-known political thinker in her native France, this is Delsol's first book to appear in English. Icarus Fallen should establish her as one of the most insightful social and cultural writers working on either side of the Atlantic. "This is simply the best book about the problems of modern man since Christopher Lasch's Culture of Narcissism . It is so crammed with truth and insight that, as someone once said of Chesterton, every line deserves a review." -- The American Conservative "An extensive evaluation of the pitfalls of modern times and the strict limits on human virtues, Icarus Fallen , is strongly recommended reading for students of 20th Century Philosophy, Politics, and History." -- Wisconsin Bookwatch.

This paper applies a proposed modified stochastic fractal search algorithm (MSFS) for dealing with all constraints of optimal reactive power dispatch (ORPD) and finding optimal solutions for three different cases including power loss optimization, voltage deviation optimization, and L-index optimization. The proposed MSFS method is newly constructed in the paper by modifying three new solution update mechanisms on standard stochastic fractal search algorithm (SSFS). The first modification is to keep only one formula and abandon one formula in (...) the diffusion process while the second modification and the third modification are used in the first update and the second update. In two updates of SSFS, solutions with low quality are updated with high probability while other solutions with high quality do not get chances to be updated. This manner results in the fact that some promising solutions around the high quality solutions can be missed. In order to tackle this restriction, the second modification of MSFS is to newly update the worst solutions in the first update and the best solutions in the second update. In the third modification, all existing formulas of SSFS in the two updates are abandoned and the same new proposed technique is used for updating such solutions in two updates. Compared to SSFS, the three modifications can bring advantages to MSFS such as using smaller number of produced solutions per iteration, spending shorter execution time, finding better optimal solutions, and owning more stable search ability. Furthermore, the proposed method also sees its effectiveness and robustness over SSFS by testing on IEEE 30-bus system and IEEE 118-bus system with three different single objectives for each system. The proposed method can find less minimum, average, and maximum for all the cases in addition to faster search speed. Besides, the proposed method is also compared to other methods such as PSO-based method group, GA-based method group, DE-based method group, and other recent methods. Result comparisons also indicate that the proposed method can be more efficient than almost all these methods with respect to less minimum and smaller values of control parameters. As a result, evaluation of the performance of the proposed method is that it should be used for seeking solutions of ORPD problem. (shrink)

The theme of this issue of Ethical Perspectives is the French tradition in liberal thought, and the unique contribution that this tradition can make to debates in contemporary liberalism. It is inspired by a colloquium held at the Katholieke Universiteit Leuven in December of 2008 entitled “In Search of a Lost Liberalism: Constant, Tocqueville, and the singularity of French Liberalism.” This colloquium was held in conjunction with the retirement of Leuven professor and former Dean of the Institute of Philosophy, (...) André Van de Putte, who found much inspiration in this tradition. A revised version of his valedictory lecture from the conference serves as the final contribution to this issue. Much contemporary liberal political philosophy is currently done in conversation with a line of liberal thinkers starting with John Locke, running through Immanuel Kant and John Stuart Mill, and culminating in the work of John Rawls and his followers. The reasons for the enormous appeal of this philosophical tradition are, among other things, the combination of the central role of the intuitively appealing value of individual liberty with a strong rationalistic, universalistic, and normative character. The thread running through most of these liberal theories is a commitment to what the French liberal Benjamin Constant referred to as “the liberty of the moderns,” that is, liberty in a negative sense, as a lack of interference in one’s activity from others and from government. This focus has expanded over time to include a richer body of civil, political, social, economic and cultural rights, for instance, in the work of liberal thinkers who have tried to integrate the insights of communitarian thought and discourse ethics in their work. However, the emphasis on individual liberty in the negative sense continues to be the normative and theoretical touchstone and default position for many contemporary liberal theories. The limitation of the canon of liberal thought to the aforementioned authors and themes deprives the contemporary debate of a rich source of ideas: the French liberal tradition. Montesquieu, considered to be the father of this tradition, provides a good example of how it can enrich current debates in liberal theory. Montesquieu’s work evinces a keen eye for the dynamics of power relations and the limitations of the power of the better rational argument. His insight that power can sometimes only be checked by an equal and opposing power, so that a system of separation and balance of powers is necessary in order to preserve liberty, is reflected in the foundations of most modern democracies. Montesquieu also argues that contingent environmental, historical, social and economic conditions play a dramatic role in determining what kind of government is appropriate for a particular society. On his view, ignoring these facts when framing a government can inadvertently end in despotism. Montesquieu’s observations challenge us to reexamine some of contemporary liberalism’s universalist and rationalist claims. Benjamin Constant is most famous for his distinction between two kinds of liberty: the liberty of the ancients and the liberty of the moderns. The ancient form of liberty manifested itself in the active political participation of citizens in the ancient republic. While this form of government and decision-making was suitable for small, homogeneous city-states, Constant argues that it is impracticable for large modern nation-states. Hence, the concept of modern liberty shifts to an emphasis on the rule of law and the non-interference of the state in private matters. This form of liberty is familiar to us from contemporary liberalism – and Constant cherishes this form of freedom as much as any liberal does today. However, his position is complex: he also argues that the liberty of the ancients should not be neglected. Active political participation is needed to ensure that the government is executing its duty of preserving the modern form of liberty by publicly pointing out violations. The contemporary relevance of Constant’s work is clear when we consider the alleged “democratic deficit” that plagues the EU and international institutions such as the UN, the IMF, and the World Bank. Not only does this democratic deficit threaten the modern form of liberty by placing decision-making processes out of sight of the people, it also threatens citizens’ sense of self-respect derived from self-governance. Constant’s argument for the necessity of combining the liberty of the ancients with that of the moderns provides a fruitful resource for confronting these contemporary issues. Tocqueville’s work on liberalism benefits from his opportunity to observe a society founded on liberal democratic principles – the United States of America – in action. In his Democracy in America, he examines the social consequences, both intended and unintended, of building a society on ‘the equality of conditions’, as he defines ‘democracy’. Tocqueville sees a tension between the democratic value of equality and the aristocratic value of the rule of the best. He observes that democratic societies do not necessarily choose the best leaders and instead promote mediocrity instead of virtue, talent, and excellence. Democracy also confronts citizens with the threat of ‘soft despotism’, where a government that preserves the outer signs of the liberty of the moderns nevertheless controls the behavior of its citizens in minute detail through a system of detailed rules ostensibly aimed at their welfare. This paternalism is an even more insidious threat to liberal values than the hard variety of despotism, since it is so difficult to detect and done in the name of liberal values themselves. Taking Tocqueville’s observations seriously would add complexity to attempts to theorize about the modern social-democratic welfare state. The contributions to this issue supplement and critique mainstream liberal thought and its relation to contemporary issues through a serious engagement with the French liberal tradition. Annelien De Dijn’s contribution discusses Bertrand de Jouvenel, a lesser-known 20th Century representative of the French political tradition she terms ‘aristocratic liberalism’. This tradition has its roots in the work of Montesquieu, and emphasizes the importance of intermediary bodies, most importantly the aristocracy, in providing a check to the top-down power of despotic state authorities and the bottom-up power of revolutionary leveling tendencies, both of which threaten liberty. De Dijn situates Jouvenel in this tradition, but then indicates an important difference between his thought and that of his predecessors: his most significant work, On Power, is not only on French history, but on European history. Pointing to the enthusiastic reception of this work in the Anglophone world, she suggests that the rise of totalitarianism in Europe gave the anti-totalitarian features of aristocratic liberalism a broader appeal. Valentino Lumowa’s paper concerns Constant’s classic text, The Liberty of the Ancients Compared with that of the Moderns. Lumowa argues that in order to understand Constant’s piece, we must be aware that its two parts were written under different historical circumstances and decipher the argumentative thrust inherent in the text. Following Stephen Holmes, he argues that to understand the shift Constant made in the second part of the text, we should read it within the context of the increasing influence of the ultra-Royalists in the legislature during the Bourbon Restoration. However, in contrast to Holmes, he contends that the spirit of both civic and individual freedom, which enlivens representative system, is the backbone of the text in its unity. Demin Duan’s essay investigates an apparent ambivalence between liberal and imperialist tendencies in the work of Alexis de Tocqueville, which has already drawn some attention from Tocquevillian scholars. These interpretations of Tocqueville and his writings on empire generally agree that Tocqueville stands in a recognized tradition of liberalism, which is characterized by respect for human rights, individual freedom and a sense of universal humanism. On this standard view, Tocqueville’s support of imperialism represents nothing but an unfortunate breach of his own otherwise consistent liberal thinking. Duan’s article questions this standard position. By questioning the assumption of Tocqueville’s liberalism in the first place, he tries to gauge the influence of both the old republican tradition and the new liberal perspective on his thinking. In conclusion, he argues that Tocqueville’s overall thought, especially his notion of freedom, is very much informed by an old republican tradition. His support of French imperialism could be better understood from this perspective rather than be rendered simply as a deviation from liberal norms. Pawel Marczewski’s contribution is an attempt to show that Tocqueville’s conception of liberty transcends the divisions between negative and positive aspects of freedom. He begins by juxtaposing this conception with the opposition drawn by Constant between liberty of the ancients and liberty of the moderns. While Tocqueville and Constant shared a concern for the preservation of individual rights, Tocqueville was much more reluctant to accept the modern loss of the communal dimension of liberty. He did not accept the view that jouissances privées, private pleasures, are the main compensation that the modern world has to offer for the lost ancient treasure of political participation. The essay then looks into the relevance of Tocqueville’s standpoint for current debates between liberal defenders of negative freedom and republican advocates of freedom as non-domination. Participants on both sides of the debate seem to be so devoted to showing that their particular approach provides the best guarantees against actual and possible threats to liberty that they overlook the fact that their definitions of freedom remain significantly similar. By arguing that ‘to be free is to be guided by one’s own will’, contemporary republicans, as well as their liberal counterparts, move along the lines drawn by Constant towards private pleasures. By questioning the inevitability of this turn, Tocqueville provides us with a valuable contribution to these discussions in contemporary political philosophy. Finally, André Van de Putte’s contribution, an adaptation of his emeritus speech that closed the conference on French Liberalism, appeals to Tocqueville in order to draw attention to the importance of intermediary, dialogical bodies in mitigating the implicit despotic tendencies of the democratic drive to equality. In Tocqueville’s view, the transition from the feudal corporate inequality to democratic individual equality was not a clean break. Rather, this transition is a continual process of democratization that is driven by a desire for equality, or egalité des conditions. This dissolution of distinctions of estate, class and status has the unintended consequence of concentrating the diffuse power of these entities into a centralized state, which is responsible for ensuring the equality of all under the law. This process leaves increasingly isolated and atomized individuals to face the power of a monolithic state in defense of their freedom, and moves toward a soft, paternalistic despotism. Constant’s freedom of the moderns is not sufficient to protect individuals from this centralized power. Democracy also requires the political freedom of the ancients. Van de Putte argues for a system in which atomized individuals organize themselves into intermediary bodies that, in a Montesquieuian balance of powers, can enter into dialogue with each other and the state on more equitable terms. Van de Putte’s contribution closes with a plea for a conception of democracy as a regime of dialogue. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Descartes and Method: A Search for a Method in MeditationsPatrick FriersonDaniel E. Flage and Clarence A. Bonnen. Descartes and Method: A Search for a Method in Meditations. New York: Routledge, 1999. Pp. 332. Cloth, $90.00.The book has two parts. The first (Chapters 1-3 and an appendix) outlines Descartes's method of analysis, a method for discovering laws and clarifying ideas. The second (Chapters 4-10) offers a (...) running commentary of the Meditations that can be read on its own and is valuable not only for specialists as a challenging comprehensive account but also for anyone looking for a concise and coherent secondary source.The method is taken from the Discourse and illustrated using the Optics. According to the authors, analysis in the search for laws "is a type of argument to the best explanation" (23) that involves "two different issues, discovery and confirmation" (21). In discovery, one isolates a phenomenon and posits one or more explanations (or causes) for it. In confirmation, one tests this explanation for "material truth" (whether it is recognized as true by the natural light). Then one shows how the phenomenon is "caused" by the explanation, and that it is the best explanation, and that it can be included in a systematic science.The discussion of analysis in the clarification of ideas argues against " 'the epistemic thesis,' that is, the thesis that all innate ideas are (materially) true and known to be true as soon as they are considered"(45). Most of the arguments here address the claim that innate ideas are known to betrue. These arguments are followed by an account of how analysis clarifies ideas through successive refinement, and an illustration of this method from Descartes's clarification of the idea of light in the Optics. The final chapter of the section on method defends the claim that Descartes uses "cause" to refer to formal rather than efficient causation.The authors then turn to the Meditations, offering a virtually line by line treatment of major themes, with attention to showing how the method outlined in part one structures the arguments of the Meditations. Meditations 1-3 "ascend" through discovery and preliminary confirmation, ending with a perfect, non-deceiving God as the best explanation of our idea of God. The final meditations "descend" from that best explanation to its implications. This descent confirms the explanation by showing its place in a system.The second part of the book also includes explanations of the part that conceptual clarifications play in the Meditations. Flage and Bonnen discuss the cogito argument, the account of the wax, the arguments for the existence of God, and the distinction of mind and body, all as examples of conceptual clarification through the method of analysis. In the case of God, for instance, Descartes begins with Hobbes's crude conception of God and clarifies it into the simple, clear, and distinct notion of a "most perfect being."The last chapter addresses the circle ascribed to Descartes by Arnauld: that the argument for the existence of God depends on the truth of clear and distinct ideas, which is only established on the basis of the existence of God. The authors argue that this is not a true circle, since Descartes assumes the material truth of clear and distinct ideas (which is indubitable) in his early argument and draws on their formal truth (in the mind of God) only after he proves the existence of God. They suggest their own circle, however: in his response to other concerns of Arnauld, Descartes suggests that God [End Page 436] stops a causal regress and thus commits himself to the formal truth of the idea of God, which he cannot independently justify.As one would expect in a book that offers a concise and unified interpretation of the Meditations, readers will find unnecessary asides and wish for attention to issues that are passed over. Moreover, though the authors support some views with extensive quotations, they leave others without textual support. The most unfortunate example is the identification of formal truth with actuality. The authors have several accounts of the distinction between formal and material truth and end their book with...

Leibniz has long faced a challenge about the coherence of the distinction between necessary and contingent truths in his philosophy. In this paper, I propose and examine a new way to save genuine contingency within a Leibnizian framework. I conclude that it succeeds in formally solving the problem, but at unbearable cost. I present Leibniz’s challenge by considering God’s choice of the best possible world (Sect. 2). God necessarily exists and necessarily chooses to actualise the best possible world. (...) The actual world therefore could not be different, for if it were different it would be a distinct and inferior world and hence would not be created. In Sect. 3 I defend Leibniz from this challenge. I argue that while it is necessary for God to choose to create the best possible world, it is not necessary for any world to be the best possible. This is because the criterion for judging perfection can itself be contingent. Different criteria will judge different worlds as the best. Thus it is necessary for God to create the best, but not necessary which is the best. Distinguishing between possible worlds in Leibniz’s sense and in the modern sense allows a fuller exposition of this position. There are worries that can arise with the claim that the criterion of perfection is contingent. I consider two of the most pressing (Sect. 4). The first argues that the criterion is in God’s understanding and hence is necessary; the second alleges that a contingent criterion of perfection violates Leibniz’s cherished Principle of Sufficient Reason. These worries are well-grounded, and examining them reveals a deep incompatibility between this solution and Leibniz’s metaphysical views. I conclude that there is a real solution available, but that it is unacceptable to Leibniz or a Leibnizian. The search for a genuine solution that is genuinely Leibnizian goes on. (shrink)

Network reconfiguration is one of the most effective methods to reduce line power loss in the distribution system, which causes higher losses than the other parts of the power system. This paper proposes a modified symbiotic organisms search algorithm to solve the NR problem. For the purpose of enhancing the effectiveness of MSOS, the mutualism and parasitism strategies of the original symbiotic organisms search have been modified to create better new solutions. In the mutualism strategy, the so-far (...) class='Hi'>best solution is updated immediately as soon as new solutions are created. In the parasitism strategy, the update is only implemented for the first half of control variables, whereas another half still remains unchanged. The comparison results between MSOS and SOS on twenty-five benchmark functions and different scales of test distribution systems with 14, 33, 69, and 119 nodes show that the improvement level of MSOS over SOS is significant with higher success rates and better quality of gained solutions. Similarly, MSOS also reaches better results than other methods in the literature. Consequently, MSOS can be a favorable method for determining the most appropriate configurations for the distribution systems. (shrink)

I argue for an epistemic conception of voting, a conception on which the purpose of the ballot is at least in some cases to identify which of several policy proposals will best promote the public good. To support this view I first briefly investigate several notions of the kind of public good that public policy should promote. Then I examine the probability logic of voting as embodied in two very robust versions of the Condorcet Jury Theorem and some (...) related results. These theorems show that if the number of voters or legislators is sufficiently large and the average of their individual propensities to select the better of two policy proposals is a little above random chance, and if each person votes his or her own best judgment (rather than in alliance with a block or faction), then the majority is extremely likely to select the better alternative. Here ‘better alternative’ means that policy or law that will best promote the public good. I also explicate a Convincing Majorities Theorem, which shows the extent to which the majority vote should provide evidence that the better policy has been selected. Finally, I show how to extend all of these results to judgments among multiple alternatives through the kind of sequential balloting typical of the legislative amendment process. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:If “Reality is the Best Metaphor,” It Must Be VirtualMarguerite R. Waller (bio)What is the search for the next great compelling application but a search for the human identity?—Doug Coupland, Microserfs... we can look forward to a richly textured and complex cyberspace, where we are at all times human, and can become bits of pixel dust flying through a virtual landscape.—3-D, multiuser, interactive, on-line virtual reality (...) producer“Avatars are Next,” the June 1996 issue of Wired announces on its cover, above a glossy foldout of Bill Gates in bathing trunks floating on a lemon yellow air mattress in a sensuous Hockney-blue swimming pool. “Mr. Bill goes Hollywood! Special Gatesfold Issue,” reads the caption underneath the (photomontaged) naked torso. The United States Congress’s attempt in February 1996 to conceptualize the Internet as an incitement to indecent sexual conduct (in Section 507 of the 1996 Telecommunications Act, the so-called Computer Decency Act) is clearly the lampooned subtext of this juxtaposition of sexualized body with the concept of the avatar. The antithesis of sensuous, avatars are bandwidth-conserving, virtual figures that take the place of users’ physical bodies in the three-dimensional, interactive, multiuser virtual environments that software developers in 1996 insist will be the telos of the development of the World Wide Web. The Wired cover implies that the nerd community finds Congress’s association of digital media with sex ridiculous (however flattering they may find it to be constructed as sexually dangerous). Not unusually, sexuality is being invoked by the state as a justification for extending its own reach (and the corporate interests it represents).But the sex/gender politics of Net free speech advocates are not necessarily more progressive. As feminist commentator Laura Miller argues in “Women and Children First: Gender and the Settling of the Electronic Frontier,” the metaphor of a frontier beyond the jurisdiction of Congress, deployed by opponents of federal regulation, draws upon a conventional construction of gender that threatens to reinscribe women as victims, reinforcing “the power imbalance between the sexes, with its roots in the concept of women as property, constantly under siege and requiring the vigilant protection of their male owners” [53]. The unintended consequence of this conceptualization, she worries, is that “the threat of regulation is built into the very mythos used to conceptualize the Net by its defenders” [50].My worry, therefore, embraces both sides of the debate over free speech on the Net. The skirmish between Big Brother and the software pioneers seems to be shaping up rhetorically as a classic fraternal competition “between men” (Sedgwick). We may read it as a contest between fundamentally congruent “male” subject positions, both of which incline to disempower “female” subject positions and both of which stand to increase their [End Page 90] own political and economic capital by the appearance of a conflict. The power-producing relationality at play in this turf war, however, simultaneously threatens to subvert the claims of each position to its own, independent ontology. Both parties, therefore, can be expected compulsively to deny their relational status. John Perry Barlowe insists, in his “Declaration of Independence in Cyberspace”: “Your legal concepts of property, expression, identity, movement, and context do not apply to us. They are based on matter. There is no matter here.”It is this more subtle metaphysical issue, the occlusion of relation, implicated in but not reducible to, the constructions of sexuality and gender deployed by both Netizens and Congresspeople, that I find the most pressing issue in designs, uses, and discussions of cyberspace. I will argue that, in fact, the current wave of Internet development (both practically and discursively) is in some sense driven by a desire to make cyberspace safe for essentialist subjectivities of whatever ideological/political persuasion. I will unfold this argument in terms of a certain notion of addiction. My interest is not “cyberaddiction” per se, in the sense of individuals who spend what they or their associates consider too much time on-line, but rather the construction of cyberspace—both rhetorically and electronically—as a clean, clear realm in which we can transcend positionality while remaining (or becoming more fully) “ourselves.” I am not, that...

This review article discusses the relationship between deference and the presumption of constitutionality, as discussed in Brian Foley’s book, Deference and the Presumption of Constitutionality. Foley argues for the rejection of the presumption of constitutionality as it operates in the Irish Constitution, proposing instead a ‘due deference’ approach. This approach would require courts to give varying degrees of weight to the legislature’s conclusions that particular legislative provisions are constitutional. The article praises Foley’s book, particularly its stronger justification of due deference (...) which focuses on its ability to foster a culture of justification which, in turn, facilitates popular sovereignty. The review also provides a criticism of the argument made in the book and discusses its application to the UK constitution. First, the review argues that the focus on constitutional as opposed to institutional factors to determine deference may, in practice, undermine Foley’s justification of due deference. Second it argues that Foley’s justification of deference may be best served in the UK constitution by a theory of democratic dialogue as opposed to the application of due deference. (shrink)

Two questions dominate theoretical research on vagueness. The first is of a logical-semantic nature: What formal models offer the best understanding of vagueness? Many answers to this question have been proposed (e.g. [1], [2] for an overview), but none of these has found general acceptance so far. The second question is of a pragmatic nature and asks Why is language vague? This question has been asked forcefully by the economist Barton Lipman, who has shown that some seemingly plausible (...) answers resist analysis in terms of classical Game Theory [3], [4]. While a number of tentative answers to this question have been suggested (for a survey, see [6], [7]), Lipman’s question is still partly unresolved, particularly with respect to situations where there is no conflict between the speaker and the hearer (cf. [8]). (shrink)

We are still searching for an adequate theory of the first amendment freedom of speech. Despite a plethora of judicial opinions and scholarly articles, there are fundamental conflicts over the meaning of the words "Congress shall make no law... abridging the freedom of speech." This Article examines the possibility that recent developments in social theory can aid our understanding of the freedom of speech. My thesis is that Jiirgen Habermas' theory of communicative action can serve as the basis for (...) an interpretation of the first amendment that fits the general contours of existing first amendment doctrine and provides a coherent justification for the freedom of speech. Habermas' theory takes as its point of departure the speech act theory developed through contemporary analytic philosophy and linguistics. The central theme of speech act theory is that speech is action; communication coordinates individual behavior through achieving rational understanding. An important corollary is the proposition that communication is intersubjective; speech acts involve both speakers and listeners. In addition, the theory of communicative action makes a distinction between communicative action-oriented to the coordination of behavior through rational agreement-and strategic behavior-the use of speech to manipulate, coerce, or deceive. I argue that a theory of free speech can incorporate this distinction to mark the boundaries of the right to free speech: freedom of speech is freedom to engage in communicative action, not strategic action. Another component of Habermas' theory is the ideal speech situation, in which rational agreement may be reached because distorting factors are excluded; this ideal situation serves as the basis of a principle of equality of communicative opportunity that can give the freedom of speech its fundamental content. Habermas' theory of communicative action provides the basis for my reinterpretation of the first amendment freedom of speech as the freedom of communicative action. This Article has two aims. My first aim is to develop a theory of the meaning of the first amendment from the theory of communicative action. In pursuit of this first goal, the Article assumes a perspective that is internal to the practice of American constitutional law. I argue that Habermas' theory has substantial power to explain and justify first amendment doctrine. Indeed, it is my view that a theory of freedom of speech based on the theory of communicative action, more so than any other theory, provides the best justification for the first amendment while simultaneously providing the best fit with the existing case law. In addition to the development of a theory of the first amendment, this Article has a second aim: From the point of view of the practice of social theory, the current Article is a "thought experiment" designed to test and elaborate Habermas' theory of communicative action. I explore various objections to and ambiguities in the theory of communicative action by taking up the attitude of a participant in the practice of legal interpretation who adopts the theory of communicative action as a practical principle for institutionalization of discourse in the public sphere. It is my hope that this thought experiment will have value in the enterprise of understanding, clarifying, and extending the theory of communicative action. For example, this Article responds to the suggestion that the theory of communicative action should be reformulated as a theory of institutionalized discourse "in the public sphere of a participatory democracy." Part II of this Article begins with a hermeneutic approach to the problem of interpreting the first amendment. Part III explores and criticizes existing theories of the freedom of expression. The theory of communicative action is explicated in Part IV; the implications of that theory for the freedom of speech are explored in Part V. Finally, Part VI applies the results to specific problems in first amendment doctrine, and Part VII draws some conclusions about the implications of this exercise for both first amendment doctrine and the theory of communicative action.

Cost-based abduction, which is a technique for identifying the best explanation for a given observation based on the assumption of a set of hypothesis, is a useful knowledge processing framework for practical problems such as diagnosis, design and planning. However, the speed of reasoning of this approach is often slow. To overcome this problem, Kato et al. previously presented a more efficient cost-based abduction system, that utilized the A * search technique, however, the time and space complexities in (...) this technique are exponential, so the identification of the optimal solution is difficult in practical applications. In this paper, we present three new systems in which the user can define the computational complexity, for identification of a near-optimal solution. First, we introduce two search control techniques; a real-time A * search approach in which the user can define the look-ahead depth or space, and the multi-agent real-time A * approach in which the user can define the number of real-time A * agents used in the search. We describe the implementation of three cost-based abduction reasoning systems for predicate logic knowledge bases and test the proposed systems using a diagnostic logic circuit problem. The results show that proposed systems can identify a near-optimal solution according to the predefined polynomial order of complexity, including the selection of either linear or exponential computational complexity. It is also shown that inference time and success rate are dependent on the user-defined parameters, that the three proposed systems exhibit similar performance characteristics, and that they all offer significant speed advantages over the previously described technique.

At first glance, Fichte and Nietzsche may strike us as intellectual contraries. For example, Fichte’s belief in historical progress and universal moral law appears to be diametrically opposed to Nietzsche’s searching critique of Enlightenment optimism. This impression is reinforced by Nietzsche’s disparaging remarks about Fichte. What is more, from the dearth of critical literature comparing the two thinkers, one might be tempted to conclude that they are broadly irrelevant to one another. In this paper, however, I argue that their (...) theories of subjectivity are in many respects remarkably similar and worthy of comparison. But I also explain how, despite this convergence, their normative philosophies end up so conspicuously at odds with one another. I begin by examining the resemblance between their denials of the substantial self (Section 1). In Sections 2 and 3, I analyse Fichte’s and Nietzsche’s positive accounts of subjectivity, self-cultivation, and the political preconditions of self-cultivation. In these latter two sections, I focus on pinpointing the conceptual juncture at which their practical outlooks begin to part, which I argue can be located in their drive psychologies and their distinct conceptions of conscience (Gewissen). These theoretical differences then generate a large-scale disagreement regarding the political systems they believe best enable self-cultivation, with Fichte favouring for a democratic regime, and Nietzsche opting for an aristocratic one. I conclude Section 3 by sketching a possible way out of this dilemma. (shrink)

The search for spaces of cooperation between the methodology of natural sciences (cognitive sciences in particular) and the phenomenological approach has gained importance over time. However, it is necessary not to lose sight of the fact that Husserlian phenomenology was first and foremost characterized by a profound critique of ontological naturalism, a critique crucial for understanding the ethical sense of the phenomenological operation. To clarify this point, it is necessary to clarify the problematic role that naturalism has played (...) - and continues to play - on the ethical level, and the way in which phenomenological criticism is able to neutralize it. In the following pages we will first try to illustrate the impact of ontological naturalism on the contemporary ethical vision and then to show how the phenomenological perspective is best understandable as a way to reveal the blind spots of naturalism, to denounce its implicit reductionism, and to reopen an ethical perspective that the historical establishment of a naturalistic worldview had artificially closed.

Some philosophers search for the mark of the cognitive: a set of individually necessary and jointly sufficient conditions identifying all instances of cognition. They claim that the mark of the cognitive is needed to steer the development of cognitive science on the right path. Here, I argue that, at least at present, it cannot be provided. First (§2), I identify some of the factors motivating the search for a mark of the cognitive, each yielding a desideratum the (...) mark is supposed to satisfy (§2.1). I then (§2.2) highlight a number of tensions in the literature on the mark of the cognitive, suggesting they’re best resolved by distinguishing two distinct programs. The first program (§3) is that of identifying a mark of the cognitive capturing our everyday notion of cognition. I argue that such a program is bound to fail for a number of reasons: it is not clear whether such an everyday notion exists; and even if it existed, it would not be able to spell out individually necessary and jointly sufficient conditions for cognition; and even if it were able to spell them out, these conditions won’t satisfy the desiderata a mark of the cognitive should satisfy. The second program is that of identifying a mark of the cognitive spelling out a genuine scientific kind. But the current state of fragmentation of cognitive science, and the fact that it is splintered in a myriad of different research traditions, prevent us from identifying such a kind. And we have no reason to think that these various research traditions will converge, allowing us to identify a single mark. Or so, at least, I will argue in (§4). I then conclude the paper (§5) deflecting an intuitive objection, and exploring some of the consequences of the thesis I have defended. (shrink)

Berkeley's essay on vision was published in the spring of 1709. It was recognised at once as a book of considerable importance, and there was a second edition within the first year. The author was still only 24. His design, he wrote, was to show the ‘manner we perceive by sight the distance, magnitude and situation of objects’. Hitherto, writers on optics had ‘proceeded on wrong principles’.

Attempting to compare scientific theories requires a philosophical model of meaning. Yet different scientific theories have at times—particularly in early chemistry—pre-supposed disparate theories of meaning. When two theories of meaning are incommensurable, we must say that the scientific theories that rely upon them are meta-incommensurable. Meta- incommensurability is a more profound sceptical threat to science since, unlike first-order incommensurability, it implies complete incomparability.

One of the foundation-stones of modern philosophy Descartes was prepared to go to any lengths in his search for certainty—even to deny those things that seemed most self-evident. In his Meditations of 1641, and in the Objections and Replies that were included with the original publication, he set out to dismantle and then reconstruct the idea of the individual self and its existence. In doing so, Descartes developed a language of subjectivity that has lasted to this day, and he (...) also took his first steps towards the view that would eventually be expressed in the epigram Cogito, ergo sum ("I think, therefore I am"), one of modern philosophy's most famous—and most fiercely contested—claims.

In Homo Deus, Yuval Noah Harari argues that technological advances of the twenty-first century will usher in a significant shift in how humans make important life decisions. Instead of turning to the Bible or the Quran, to the heart or to our therapists, parents, and mentors, people will turn to Big Data recommendation algorithms to make these choices for them. Much as we rely on Spotify to recommend music to us, we will soon rely on algorithms to decide our (...) careers, spouses, and commitments. Harari also predicts that next, the state will take away individuals’ rights to make their own choices about their lives. If Google knows where your children would flourish best in school, why should the state allow a fallible human parent to decide? Liberalism—which, as Harari uses this term, refers to a state of society in which human freedom to choose is respected and championed—will collapse. In this paper, I argue that Harari’s conception of the future implications of recommendation algorithms is deeply flawed, for two reasons. First, users will not rely on algorithms to make decisions for them because they have no reason to trust algorithms, which are developed by companies with their own incentives, such as profit. Second, for most of our life decisions, algorithms will not be able to be developed, because the factors relevant to the decisions we face are unique to our situation. I present an alternative depiction of the future: instead of relying on algorithms to make decisions for us, humans will use algorithms to enhance our decision-making by helping us consider the most relevant choices first and notice information we might not otherwise. Finally, I will also argue that even if computers could make many of our decisions for us, liberalism as a political system would emerge unscathed. (shrink)

This seminal paper, which marks a turning point of the chemical revolution, is presented for the first time in a complete English translation. In this first half Lavoisier undermines phlogiston chemistry by arguing that his French contemporaries had replaced Stahl’s original theory with radically different systems that conceptualised the phlogiston principle in completely incompatible ways. He refutes their claims by showing that these later models were riddled with inconsistencies as to phlogiston’s weight, its ability to penetrate glass and (...) its role as a source of colour and odour in chemical compounds.

Relatively little is known about those who consistently produce the valid response to Modus Tollens (MT) problems. In two studies, people who responded correctly to MT problems indicated how “convinced” they were by proofs of conditional reasoning conclusions. The first experiment showed that MT competent reasoners found accurate proofs of MT reasoning more convincing than similar “proofs” of invalid reasoning. Similarly, there was a tendency for MT competent reasoners to find an initial counterfactual supposition more convincing than did people (...) who were less competent in MT. The second experiment showed that when individuals produced the correct MT response, and found correct MT proofs to be more convincing than “bogus” proofs, they were also less likely to find the conclusions to Denying the Antecedent, or Affirming the Consequent problems valid, compared to individuals who could not discriminate between valid and bogus MT proofs. These findings are discussed in terms of both their implications for the mental logic and mental models positions, and individual differences in System 1 and System 2 reasoning. (shrink)

This study tested four theoretical models of leadership with data from the ethnographic record. The first was a game-theoretical model of leadership in collective actions, in which followers prefer and reward a leader who monitors and sanctions free-riders as group size increases. The second was the dominance model, in which dominant leaders threaten followers with physical or social harm. The third, the prestige model, suggests leaders with valued skills and expertise are chosen by followers who strive to emulate them. (...) The fourth proposes that in small-scale, kin-based societies, men with high neural capital are best able to achieve and maintain positions of social influence (e.g., as headmen) and thereby often become polygynous and have more offspring than other men, which positively selects for greater neural capital. Using multiple search strategies we identified more than 1000 texts relevant to leadership in the Probability Sample of 60 cultures from the Human Relations Area Files (HRAF). We operationalized the model with variables and then coded all retrieved text records on the presence or absence of evidence for each of these 24 variables. We found mixed support for the collective action model, broad support for components of the prestige leadership style and the importance of neural capital and polygyny among leaders, but more limited support for the dominance leadership style. We found little evidence, however, of emulation of, or prestige-biased learning toward, leaders. We found that improving collective actions, having expertise, providing counsel, and being respected, having high neural capital, and being polygynous are common properties of leaders, which warrants a synthesis of the collective action, prestige, and neural capital and reproductive skew models. We sketch one such synthesis involving high-quality decision-making and other computational services. (shrink)

Some recent exchanges (Gebharter 2017a,2017b; Baumgartner and Cassini, 2023) concern whether composition can have conditional independence properties analogous to causal relations. If so, composition might sometimes be detectable by the application of causal search algorithms. The discussion has focused on a particular algorithm, PC (Spirtes and Glymour, 1991). PC is but one, and in many circumstances not the best, of a host of causal search algorithms that are candidates for methods of discovering composition provided appropriate statistical relations (...) obtain. The discussion raises two issues: 1. Does the structure of the composition relation entail probability relations such that PC and like algorithms cannot discover composition from frequency data about kinds; and 2. what can be discovered—and how—about the composition of systems by PC or related causal search algorithms that exploit conditional independence relations. Baumgartner and Cassini answer the first question positively: constitution entails probability relations incompatible with discovery by PC. They do not engage the second question, but we will.

BackgroundOne of the next frontiers in HIV research is focused on finding a cure. A new priority includes people with HIV (PWH) with non-AIDS terminal illnesses who are willing to donate their bodies at the end-of-life (EOL) to advance the search towards an HIV cure. We endeavored to understand perceptions of this research and to identify ethical and practical considerations relevant to implementing it.MethodsWe conducted 20 in-depth interviews and 3 virtual focus groups among four types of key stakeholders in (...) the United States (PWH, biomedical HIV cure researchers, HIV clinicians, and bioethicists) to obtain triangulated viewpoints because little was known about the ethics of this topic. Each group was queried as to ethical considerations, safeguards, and protections for conducting HIV cure-related research at the EOL to ensure this research remains acceptable.ResultsAll four key stakeholder groups generally supported HIV cure-related research conducted at the EOL because of the history of altruism within the PWH community and the potential for substantial scientific knowledge to be gained. Our informants expressed that: (1) Strong stakeholder and community involvement are integral to the ethical and effective implementation, as well as the social acceptability of this research; (2) PWH approaching the EOL should not inherently be considered a vulnerable class and their autonomy must be respected when choosing to participate in HIV cure-related research at the EOL; (3) Greater diversity among study participants, as well as multi-disciplinary research teams, is necessitated by HIV cure-related research at the EOL; (4) The sensitive nature of this research warrants robust oversight to ensure a favorable risk/benefit balance and to minimize the possibility of therapeutic misconception or undue influence; and (5) Research protocols should remain flexible to accommodate participants’ comfort and needs at the EOL.ConclusionBecause of the ethical issues presented by HIV cure-related research at the EOL, robust ethical safeguards are of utmost importance. The proposed ethical and practical considerations presented herein is a first step in determining the best way to maximize this research’s impact and social value. More much inquiry will need to be directed towards understanding context-specific and cultural considerations for implementing EOL HIV cure research in diverse settings. (shrink)

There exist many competing philosophical definitions of joint action and no clear criteria to decide between them; so far the search for definitions has by and large been a semantical enterprise rather than an empirical one. This chapter describes and assesses several constraints that could help converge towards a set of necessary and sufficient conditions for joint action. The tightness constraint favours definitions that fit joint actions in which the links between agents are as relaxed as possible, so as (...) to better pinpoint the conceptual core of jointness. The developmental constraint asks for definitions based on realistic psychological states that could be entertained by agents less cognitively developed than ideal human beings. The motor constraint holds that definitions should refer to psychological mechanisms involved in actual human coordination. These first three constraints are discussed and dismissed, mainly because they manage to establish vague limits at best (for various reasons). I then introduce a fourth one, the efficiency constraint, based on the fact that most of our joint actions are generally successful, and according to which definitions should involve conditions that help justify this success. Finally, the rational and evolutionary versions of the efficiency constraint are examined and defended against objections. (shrink)

Among Rorty's most admired essays, and probably his most autobiographical, “Trotsky and the Wild Orchids” made its first appearance as a column in Common Knowledge during the journal's inaugural year. Here it is reprinted, thirty years later, in a symposium called “Whatever Happened to Richard Rorty?” He explains in this essay that, as a child, he loved things that would seem to others contradictory, for example the Trotskian socialism to which his family was committed and the wild orchids that (...) he would search for in the local mountains. Finding his own way between what appeared to others contrary kinds of demand or appeal, he never settled, as a philosopher and public intellectual, on syntheses that made good sense to his contemporaries. They were unable to locate him on their intellectual and political maps. As he writes, “If there is anything to the idea that the best intellectual position is one which is attacked with equal vigor from the political right and the political left, then I am in good shape.... The left's favorite word for me is ‘complacent,’ just as the right's is ‘irresponsible.’ ” The editors of Common Knowledge, a venue that Rorty helped to found, have reprinted this essay as a way of stating their view that nothing has “happened to Richard Rorty” in the past three decades that did not happen as well when he was active in his own self-defense. He was misconstrued but indispensable when alive, and has remained so in the decades since. (shrink)
