A nonlinear differential equation model is proposed to study the dynamics of HIV/AIDS and its effects on workforce productivity. The disease-free equilibrium point of the model is shown to be locally asymptotically stable when the associated basic reproduction number $$\mathcal{{R}}_{0}$$ is less than unity. The model is also shown to exhibit multiple endemic states for some parameter values when $$\mathcal{{R}}_{0} 1$$. Global asymptotic stability of the disease-free equilibrium is guaranteed only when the fractions of the Susceptible subclass populations are within (...) some bounds. Optimal control analysis of the model revealed that the most cost effective strategy that should be adopted in the fight against HIV/AIDS spread within the workforce is one that seeks to prevent infections and the treatment of infected individuals.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Hellenistic and Early Modern PhilosophyChristopher S. CelenzaJon Miller and Brad Inwood, editors. Hellenistic and Early Modern Philosophy. New York: Cambridge University Press, 2003. Pp. xii + 330. Cloth, $60.00.There are at least two ways of writing the history of philosophy: the first and most common among those self-identified as "philosophers" treats philosophers of the past as if they were in live dialogue with the present. Only the text (...) is dissected, studied, and analyzed as the interpreter attempts to reconstruct, examine, and occasionally challenge the arguments under consideration. Practitioners of this first way assume that systematic and seemingly internally coherent styles of thought are most worthy of the name "philosophy." These thinkers believe that the term "philosophy," as Richard Rorty pointed out long ago, has an "honorific" sense: philosophy as such stands above other forms of thought, it is regulative in scope, and it serves as something that examines the conclusions of other, necessarily less rigorous fields. The second way is more explicitly contextualist, seeking to understand what a past thinker may have meant in his own time, what outside factors may have shaped his arguments, and how his thought may be part of broader historical currents that are none the less worthy of being remembered and studied now. Practitioners of this way are more likely to believe that ambiguities or seeming deficiencies of clarity that we find in the work of a past thinker are unlikely to be resolved by hypothetical, propositional reconstruction; rather the ambiguities are apparent to us because we are differently situated, so that the study of history is a more powerful tool in helping us satisfactorily access the work of a past thinker than rationalistic reconstruction. (Full disclosure: I am an advocate of the second way.) This volume presents studies that fall into both of the two camps, as Jerome Schneewind points out in his cogent introduction.The volume has a manifest unity: almost all of the articles are concerned in some way with different Hellenistic schools of thought and the way early modern thinkers used, re-imagined, and interpreted them. The studies are often meticulous and all are stimulating. Anthony Long offers a wonderfully synthetic presentation of ancient Stoicism as a coherent system, after which he examines the way Spinoza, Justus Lipsius, and the eighteenth-century Anglican bishop Joseph Butler measure up; unsurprisingly, they don't measure up that well. Margaret Osler seeks to illuminate the way Gassendi appropriated certain aspects of Epicureanism. Philip Mitsis argues that modern scholarship on Locke has not taken Locke's interest in Cicero's De officiis as a tool for teaching morality seriously. Donald Rutherford studies Leibniz's critique of Stoicism, which "centers," he writes, on their "failure to offer an adequate explanation of the nature of moral progress and of the dependence of human happiness on the hope for such progress" (62-63). Catherine Wilson presents a study of the corpuscular aspect of Epicurean natural philosophy among Leibniz and his contemporaries. Jon Miller eloquently and thoughtfully discusses the way Grotius and Spinoza worked with the natural law theory of the Stoics. Among a number of excellent articles, perhaps the most interesting is Stephen Menn's. Menn makes a compelling case that Descartes's intellectual autobiography in the Discourses may be seen as part of a tradition. In it, the writer presents himself as reaching a moment of dissatisfaction with the intellectual customs with which he has come into contact and as needing to strike off into new directions, unencumbered by the vestiges of those customs. While others, most notably Dan Garber, have shown that, as Menn puts it, "none of Descartes's contemporaries seem to have thought in 1637 that they were witnessing a revolution" (142), Menn's study is striking because it shows the depth of the tradition within which Descartes was working. Next, Gail Fine finds that the Cyrenaics, as presented by Sextus Empiricus, seem to have [End Page 207] endorsed "the view that there are truths, beliefs, and knowledge about the subjective" (214). Steven Nadler seeks to show that there is no mysticism in Spinoza's thought, even though it was not uncommon in Spinoza's own day to... (shrink)

In this book, Christopher Celenza provides an intellectual history of the Italian Renaissance during the long fifteenth century, from c.1350–1525. His book fills a bibliographic gap between Petrarch and Machiavelli and offers clear case studies of contemporary luminaries, including Leonardo Bruni, Poggio Bracciolini, Lorenzo Valla, Marsilio Ficino, Angelo Poliziano, and Pietro Bembo. Integrating sources in Italian and Latin, Celenza focuses on the linked issues of language and philosophy. He also examines the conditions in which Renaissance intellectuals operated in an (...) era before the invention of printing, analyzing reading strategies and showing how texts were consulted, and how new ideas were generated as a result of conversations, both oral and epistolary. The result is a volume that offers a new view on both the history of philosophy and Italian Renaissance intellectual life. It will serve as a key resource for students and scholars of early modern Italian humanism and culture. (shrink)

Lapo da Castiglionchio the Younger was a Florentine Renaissance humanist who died in 1438 at the age of thirty-three. He took part in one of the most interesting phases of Italian Renaissance humanism and achieved in his short lifetime a modest reputation as a first-rate Greek to Latin translator. Less well known is the fact that he wrote a fair amount of prose works. One of the most interesting of these is a treatise which he composed in the year of (...) his death, entitled De curie commodis, or, On the Benefits of the Curia, a portrait of the papal Curia which is written elegantly, learnedly, earnestly, and angrily. ;The goal of this study is to discuss this dialogue in its intellectual and social contexts; there are three chapters. The first is a general introduction to Lapo's life and work, to the dialogue itself, and to the historiography on the De curie commodis. The second chapter discusses the manner in which Lapo employs the virtues in a Stoicizing fashion as persuasive tools in the environment of Italian humanism. It is argued that his particular treatment of the virtues can serve as a key for interpreting the dialogue as a whole. The third chapter touches both on social historical issues in the De curie commodis and on Lapo's defense or curial wealth. ;There has been no adequate edition of the Latin text, based on a wide enough variety of extant manuscripts, nor has the De curie commodis ever been translated into English . Therefore, a thorough critical edition of the Latin text along with an annotated English translation follows the discussion. ;The treatise has been notoriously difficult to interpret and seems often to prevaricate. The interpretive conclusion of this study is that Lapo wrote as a well-informed but liminal figure in the socio-cultural environment of the papal Curia--as an outsider who desired to become a full-fledged insider. The De curie commodis is not the parting shot of a fed-up hanger-on; it is instead Lapo's last-ditch, highly critical but nonetheless sincere attempt to find a patron who would allow him to join a cultural ambient at which he marvelled but from which he felt himself unjustly excluded.

This is a book about sensory states and their apparent characteristics. It confronts a whole series of metaphysical and epistemological questions and presents an argument for type materialism: the view that sensory states are identical with the neural states with which they are correlated. According to type materialism, sensations are only possessed by human beings and members of related biological species; silicon-based androids cannot have sensations. The author rebuts several other rival theories, and explores a number of important issues: the (...) forms and limits of introspective awareness of sensations, the semantic properties of sensory concepts, knowledge of other minds, and unity of consciousness. The book is a significant contribution to the philosophy of mind, and has much to say to psychologists and cognitive scientists. (shrink)

This book presents a comprehensive theory of consciousness. The initial chapter distinguishes six main forms of consciousness and sketches an account of each one. Later chapters focus on phenomenal consciousness, consciousness of, and introspective consciousness. In discussing phenomenal consciousness, Hill develops the representational theory of mind in new directions, arguing that all awareness involves representations, even awareness of qualitative states like pain. He then uses this view to undercut dualistic accounts of qualitative states. Other topics include visual awareness, visual appearances, (...) emotional qualia, and meta-cognitive processing. This important work will interest a wide readership of students and scholars in philosophy of mind and cognitive science. (shrink)

Drawing on Ezekiel Emanuel’s controversial piece ‘Why I hope to die at 75,’ I distinguish two types of concern in ethical debates about extending the human lifespan. The first focusses on the value of living longer from prudential and social perspectives. The second type of concern, which has received less attention, focusses on the value of aiming for longer life. This distinction, which is overlooked in the ethical literature on life extension, is significant because there are features of human psychology (...) and the structure of a life that should give pause when considering how long one should aim to live, but which do not neatly coincide with considerations about how valuable additional life is likely to be. I argue that, while Emanuel’s case for hoping to die at 75 is unconvincing, he nonetheless provides weak pro tanto considerations in favour of taking a moderate life span as a prudential aim around which to base at least some significant life plans.

S. Celenza Johns Hopkins University What is "philosophy"? Who is a "philosopher"? These questions underlay much of Salvatore Camporeale's work, and they are deeper than one might suppose. We can begin with one of Camporeale's favorite figures, Lorenzo Valla, and listen to one of the ways (...) he answered these questions. In the introduction to his work reforming Aristotelian logic, the Repastinatio totius dialectice, Valla situates the debate on wisdom by recalling the case of Pythagoras.1 "What a marvelous praise of modesty it was," Valla wrote, when Pythagoras, asked whether he considered himself wise, replied that he was not "wise," but was rather a "lover of wisdom"—not sophos, but philosophos.2 Valla uses here a humanistic trope, found also in Petrarch's advice to Luigi Marsili, to the effect that Marsili should shape the practice of his life in order to become a "verae sapientiae amator," a "lover of true wisdom."3These citations from Petrarch and Valla alert us to the well-studied fact that, in the view of some humanists, academic "philosophy" had usurped the name "philosophy" and the self-searching meaning behind it. Certain humanists were proposing an alternative notion of what wisdom signified and consequently of what philosophy itself—the "love of wisdom"—represented. It seemed that wisdom needed to be located in a more persuasive way in the world of human beings, history, and language, rather than in one of eternal [End Page 483] suprahuman essences; in short, "philosophy" had to be brought closer to rhetoric and philology.The goal of this paper is to examine this idea in a twofold manner: through the history of terms and concepts as these are refracted by and through the history of institutionalized learning; and through a brief foray into Valla's preface to his great critique of western logic. There has been a lot of challenging and interesting work on this topic in the last few decades. At the same time, there may be cause to wonder whether relatively recent historians have unwittingly become too bogged down in names, failing to see the real conflict. They have tended to assume that the modern, sharp separation of humanistic "disciplines," such as rhetoric and philosophy, existed in the same way and with the same force of conviction in the premodern era. True, there are famous ancient, medieval, and early modern examples of self-defined "philosophers" differentiating themselves from "philologists" and vice versa, most notably Seneca, who—lamenting the professionalization of education in his day—complained in a letter that "what was once philosophy, has become philology" (Ep. 108.23). Yet, the more one investigates this problem, and the more one peers beneath the surface of the seemingly stark divisions between "philosophy" and "philology," the more difficult this strong separation is to maintain.This notion of the possible interpenetrability of "philosophy," and "philology," and "rhetoric" as concepts was probably easier to understand in the Renaissance than it is now. The differences between the Renaissance and our own era lie in institutional context and personal approach, both of which have been, for about six or seven intellectual generations now (but no more than that), supported by a fourfold set of assumptions about what "real" or "professional" philosophy represents: first, that philosophy is primarily about metaphysics and ontology, or rather that there exists a hierarchy in which metaphysics and ontology stand at the top; other things, such as history, language, or rhetoric are "just not philosophy." Second, a retrospectively understood Cartesian split between mind and body is basically true (and that it is legitimate to project that dualistic split back onto thinkers who did not hold the same sort of dualism as axiomatic); and consequently third, that epistemology should be privileged, that is, that knowing and the study of how knowing happens are primarily what philosophy is about. Hence "philosophy" is regulative, a master-discipline that oversees the truth claims of all... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Dr. Ambedkar and Untouchability: Fighting the Indian Caste SystemChristopher S. QueenDr. Ambedkar and Untouchability: Fighting the Indian Caste System. By Christophe Jaffrelot. New York: Columbia University Press, 2005. xiii + 205 pp.Outside of India, Bhimrao Ramji Ambedkar remains virtually unknown. Everyone knows that Mahatma Gandhi led the fight for Indian independence and that his nonviolent marches inspired Dr. King and the American civil rights movement. Most educated men (...) and women have heard of Nehru and some of the political and literary figures that India has produced in modern times. But few know of the first Untouchable to attend college, who went on to earn advanced degrees in the social sciences and law at Columbia University, the London School of Economics, and Grays Inn, who returned to India in the 1920s to launch a civil rights movement for Untouchables, [End Page 168] who drafted the constitution for the Republic of India as its first law minister, and who led a mass conversion to Buddhism weeks before this death.Dr. B. R. Ambedkar (1891–1956) is venerated by millions of Buddhist and low-caste followers in India today, and at the same time feared by politicians determined to preserve the Hindu caste system he vowed to destroy. Admirers call him Babasaheb Ambedkar or simply Baba, using a traditional term of respect for a guiding elder, and many use the greeting Jai Bhim (“Victory to Bhimrao”) within the Untouchable communities. Ambedkar is portrayed on ubiquitous wall calendars, public statues, and home altars alongside that of the Buddha, wearing a Western suit and tie, with the horn-rimmed glasses and pocket pens of a scholar and diplomat. Although widely regarded as a bodhisattva or Buddhist saint, he is never pictured in the robes of a holy man or entreated in prayer by his devotees. And while most of his campaigns for Untouchable human rights were driven back by the Hindu nationalists, many of the provisions of his path-breaking legislation were eventually adopted after his death. In the intervening decades, amid deepening polarization over his legacy, the state government of Maharashtra has published eighteen volumes of Ambedkar’s collected works and the government of India has bestowed on him its highest civilian honor, the Bharat Ratna.Given the dearth of Western scholarship on Ambedkar’s place in the history of modern India and the emergence of socially engaged Buddhism, I welcome Chris-tophe Jaffrelot’s Dr. Ambedkar and Untouchability: Fighting the Indian Caste System. As a social scientist and director of the Centre d’Études et de Recherches Internatio-nales (CERI) who has published more than a dozen books on South Asian politics, Jaffrelot is well qualified to assess Ambedkar’s life and thought. Drawing on a wide range of materials on the social reform movements of the nineteenth and twentieth centuries and Ambedkar’s contributions to sociology and politics, the author aims to redress Ambedkar’s neglect by Indian scholars before the 1990s, when the low-caste movement began finally to gain traction. However, he does not address the anomaly of Ambedkar’s neglect by all but a small circle of Western authors.1The strength of Dr. Ambedkar and Untouchability is its concise analysis of the geographical, political, and social context of Ambedkar’s career. Jaffrelot shows how British recruitment of the Mahars, members of Ambedkar’s lowly but numerous caste, for service in the colonial army resulted in disproportionate levels of literacy. Ambedkar was the fourteenth child in such a military family, whose father held the rank of major and served as a school master for the barracks. Both parents and all of Bhimrao’s uncles could read and write, compared to less than one percent of Mahars in village life. Moreover, in spite of his brilliance and determination, Ambedkar could not have continued his education without the financial support of Maratha maharajahs who opposed the Brahmins’ monopoly in education. “Ambedkar was the heir to a regional tradition; his struggle harked back to the anti-Brahmin movements which emerged in western Maharashtra from the mid-nineteenth century onward, a precocity that only the Dravidian South—the other key area of anti-Brahmin mobilization—could match.”Jaffrelot presents...

In the first chapter of his Knowledge and Lotteries, John Hawthorne argues that thinkers do not ordinarily know lottery propositions. His arguments depend on claims about the intimate connections between knowledge and assertion, epistemic possibility, practical reasoning, and theoretical reasoning. In this paper, we cast doubt on the proposed connections. We also put forward an alternative picture of belief and reasoning. In particular, we argue that assertion is governed by a Gricean constraint that makes no reference to knowledge, and that (...) practical reasoning has more to do with rational degrees of belief than with states of knowledge.

This chapter examines a sampling of the beliefs and practices to ascertain whether there are emerging patterns that link the otherwise independent, globally dispersed movements of engaged Buddhism. The rise of socially engaged Buddhism since the middle of the last century has been intensively documented and analyzed by scholars for more than 30 years. The doctrines of suffering (dukkha) and action‐rebirth (karma‐sasāra), and the moral guidelines known as Five Precepts (pañcasila), may be taken as markers of the philosophical breadth and (...) depth of the new Buddhism, and of its readiness to enter into dialogue with philosophies and theologies beyond its borders.

These pleasant memories of my teachers lead to some not-so-pleasant memories, as I disregarded their warnings and I immersed myself in the Buddhist canonical writings, commentaries and modern interpreters.

And I discovered, to my surprise and delight, that there were many commentators (...) ready to argue that a certain teaching, doctrine, or perspective was indeed what Buddhism is all about. (shrink)

One of the strongest objections to the development and use of substantially life-extending interventions is that they would exacerbate existing unjust disparities of healthy lifespans between rich and poor members of society. In both popular opinion and ethical theory, this consequence is sometimes thought to justify a ban on life-prolonging technologies. However, the practical and ethical drawbacks of banning receive little attention, and the viability of alternative policies is seldom considered. Moreover, where ethicists do propose alternatives, there is scant effort (...) to consider their merits in light of developing world priorities. In response to these shortcomings, I distinguish four policy options and, on the basis of a plausible intuition about fairness, evaluate their implications for a fair distribution of healthy lifespans. I claim that even in developing nations it would be fairest to favor policies that promote equal access to at least one promising category of substantially life-extending intervention: calorie restriction mimetics.

There is an important family of semantic notions that we apply to thoughts and to the conceptual constituents of thoughts - as when we say that the thought that the Universe is expanding is true. Thought and World presents a theory of the content of such notions. The theory is largely deflationary in spirit, in the sense that it represents a broad range of semantic notions - including the concept of truth - as being entirely free from substantive metaphysical and (...) empirical presuppositions. At the same time, however, it takes seriously and seeks to explain the intuition that there is a metaphysically or empirically 'deep' relation linking thoughts to reality. Thus, the theory represents a kind of compromise between deflationism and versions of the correspondence theory of truth. This book will appeal to students and professionals interested in the philosophy of logic and language. (shrink)

As the subtitle indicates, this book is concerned with the relationship between consciousness and the physical world. It recommends a novel and disturbingly pessimistic view about this topic that it calls “naturalistic mysterianism.” The view is naturalistic because it maintains that states of consciousness are reducible to physical properties of the brain. It counts as “mysterian” because it asserts that the physical properties in question are entirely beyond our ken—that they lie well beyond the scope of contemporary neuroscience, and quite (...) likely beyond the scope of any body of scientific knowledge that we might develop in the future. Naturalistic mysterianism thus affirms the unity of consciousness with the physical world, while also claiming that the nature of that unity will forever elude us, due to inherent limits of our cognitive capacities.

Visual experience is shaped by a number of factors that are independent of the external objects that we perceive—factors like lighting, angle of view, and the sensitivities of photoreceptors in the retina. This paper seeks to catalog, analyze, and explain the fluctuations in visual phenomenology that are due to such factors.

There are two main accounts of what it is for external objects to be presented in visual experience. According to particularism, particular objects are built into the representational contents of experiences. Existentialism is a quite different view. According to existentialism, the representational contents of perceptual experiences are general rather than particular, in the sense that the contents can be fully captured by existentially quantified statements. The present paper is a defense of existentialism. It argues that existentialism is much better equipped (...) than particularism to explain the contents of hallucinations, and it defends existentialism against three objections. (shrink)

Henceforth men looked only to antiquity for the solution of every problem, and consequently allowed literature to sink into mere quotation. 2 --Jacob Burckhardt Various aspects of late antiquity in western Europe and the Florentine Renaissance bear certain similarities which, if properly examined and contextualized, can lead to a deeper understanding of both periods--of their social as well as intellectual significance, of the manner in which politics relates to culture, and [End Page 17] of the relationship between urban life in a specific sort of milieu to the mechanisms of religious and philosophical dynamism. 3 The parallels are not always exact, but various underlying patterns are present. Here the main line of argument will be that a number of aspects of late ancient thought and of Renaissance thought (especially Renaissance Latin literature of all genres) went ignored by eighteenth- and nineteenth-century scholars, thanks to certain underlying assumptions concerning what was appropriate to investigate. These assumptions were themselves related to the combination of two major factors: romantic essentializing ideas about the nature of language, inherited from the Enlightenment, and the development in the nineteenth century of nationalist, evolutionary historiographies. The results of these developments persisted into the twentieth century and can be seen to an extent even today. Nationalist Historiographies and the Problem of Language "Gentlemen, nations are thoughts of God." So Leopold von Ranke (1795-1886) used to begin his history courses in Berlin, as Jacob Burckhardt (1818-97) later remembered. 4 While Ranke himself was concerned primarily with documentary history and the evolution of the modern state, he was also part of a larger trend in the German speaking world which sought to identify, in the study of the past, the spirit, or Geist, of a given era or people, a project which had been theorized by Hegel. Ranke and others, like Johann Gustav Droysen and August Böckh, taking their point of departure from Barthold Niebuhr and, more immediately, from Wilhelm von Humboldt, saw themselves as self-consciously transcending Hegel, basing their ideas on documentary sources as opposed to a priori theorizing. 5 But certain assumptions were similar, none more so than presuppositions relating to the Volksgeist. It is not that Ranke was relentlessly teleological; [End Page 18] history was made in the process of the unfolding of events. His primary mission was the documenting and understanding of modernity, a task which, despite their later divergences in practice, Burckhardt shared. 6 The goal was, following Niebuhr's approach in classical studies, to present history in an appealing way and in a manner useful to modernity. 7 This was bound up with a larger set of movements, encompassing the search for national identity and a tendency toward locating essential characteristics of a "people." 8 One of these characteristics was language, and a central preoccupation of scholars became the manner in which culture expressed itself through language, even as philology was becoming "the first historical discipline, the model for all other historical sciences" and the general view of scholarly fields as separate, specialized entities was growing. 9In their concern with language as a vehicle for cultural transmission and as a defining characteristic of a people, nineteenth-century scholars were the heirs of the Enlightenment. Ideas of a plurality of cultures had flourished; as it was put in the Encyclopédie, language expressed the "genius of a people." If... (shrink)

This article contends that Socratic wisdom (sophia) in Plato's Apology should be understood in relation to moderation (sophrosune), not knowledge (episteme). This stance is exemplified in an interpretation of Socrates' disavowal of knowledge. The god calls Socrates wise. Socrates holds both that he is wise in nothing great or small and that the god does not lie. These apparently inconsistent claims are resolved in an interpretation of elenchus. This interpretion says that Socrates is wise insofar as he does not believe (...) himself to know what he does not know. Whether one knows is demonstrated through elenchus, which moderates between knowledge claims. Thus, elenchus is productive of a kind of wisdom even if it does not produce knowledge. This claim, if true, forms a suitable basis for Socrates' defense of himself. That it does so serves as further evidence for the interpretation of sophia as sophrosune. (shrink)

Schellenberg's book The unity of perception is full of innovative ideas and challenges to preconceptions. This discussion endorses several of Schellenberg's main contentions, but it also challenges her handling of several key topics, such as hallucinations and perceptual awareness of particulars, and it expresses doubts about the informativeness of her main analytic tool, the notion of a perceptual capacity.

The aim of this paper is to distinguish between, and examine, three issues surrounding Humphreys's paradox and interpretation of conditional propensities. The first issue involves the controversy over the interpretation of inverse conditional propensities — conditional propensities in which the conditioned event occurs before the conditioning event. The second issue is the consistency of the dispositional nature of the propensity interpretation and the inversion theorems of the probability calculus, where an inversion theorem is any theorem of probability that makes explicit (...) (or implicit) appeal to a conditional probability and its corresponding inverse conditional probability. The third issue concerns the relationship between the notion of stochastic independence which is supported by the propensity interpretation, and various notions of causal independence. In examining each of these issues, it is argued that the dispositional character of the propensity interpretation provides a consistent and useful interpretation of the probability calculus.
