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.

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)

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.

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 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)

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.

This volume presents a selection of essays by the leading philosopher Christopher S. Hill. Together, they address central philosophical issues related to four key concerns: the nature of truth; the relation between experiences and brain states; the relation between experiences and representational states; and problems concerning knowledge.

“Dromenon” was and is the rubric governing the fourth and final floor of Aby Warburg's Library. The word means “the thing done,” “the action,” and in the context of the Greek Mysteries referred to rites, as opposed to words and images. In the Warburg Library in London, dromenon covers law, social institutions, folklore, and customs, among which Warburg located politics. This essay is in large part a reflection on what Warburg understood by politics and its inherent conflict with libraries. For (...) Warburg, both politics and libraries were ways of managing time; and the basic irony underscored in this article is that academic politics in the UK is now threatening the Warburg Library's continued existence.

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)

Thanks to a helpful tetradic diagram found in the expanded fifth edition of John Deely’s Basics of Semiotics, in which the context and circumstances of a sign’s utterance (in addition to the sign-vehicle itself and the immediate object of the sign) is distinguished from all that is explicit in the sign itself apart from the context and circumstances of its utterance, it is possible to bring Deely’s insights to bear upon the semiotically suggestive work of Marshall McLuhan. McLuhan’s implicitly semiotic (...) understanding of analogy is structurally present in his efforts to visually articulate the “laws of media” with his own “tetrad” diagrams. Deely’s discussion of the irreducible triadicity of signs therefore illuminates McLuhan’s attempt to understand how analogical thought actually works on the most fundamental structural level in the cognition of the semiotic animal. There is a unique cognitive syntax to analogy, which is operative in the animal that Deely has most appropriately identified as “the semiotic animal”. This article discusses McLuhan’s understanding of analogy in terms of its figure/ground structure, by using the example of the thermometer from Deely’s Basics of Semiotics. In relating this example to McLuhan’s tetrad, it is shown how McLuhan’s implicitly semiotic analysis can also increase our semiotic understanding of other technological tools, such as Skype videoconferencing.

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)

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. As a graduate student, I wanted desperately to find a central idea or principle on which to hang all the others, if only to prepare more efficiently for the comprehensive examinations I would face before proceeding to the dissertation. 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)

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)

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.

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)

The purpose of the article is to determine the nature of the artwork and the scope of the world revealed therein. the artwork is that by which art becomes actual. it is that in which art is expressed. however, it is more than an object of aesthetic experience. it is the revelation of a people's world. here the world means the world of a particular people at a particular time, the cultural and "intellectual atmosphere" of a historical people. a people's (...) world is their being, therefore, artwork is an epochal manifestation of a people's openness to being.

The question of concentration, or to use a word more in tune with the true nature of this essay, the heart, of this work is to explore the constructs surrounding the very nature and essence of the human heart. By heart I mean not the organ of flesh and blood, or the muscle that pumps life through out our corporal beings. But rather I mean to speak of an emotion that exists in parallel to the spirit or soul of the (...) human cognitive existence. I have chosen the title of this essay for a very specific reason, being that love and the human heart are two different concepts that I find to be closely related and essential for the other to exist. However, I findthat they are different and should be treated as such, for this reason I have given this essay a two-fold thesis. In that its main function will be to incorporate the idea of love with the ideologies of the human heart but also that they should be discussed separately. To most accurately address these points there will be three sections to this essay; the first will be an address on love and its meaning and purpose, the second will be in regards to the mystics of the heart, while the third will be a link between the two and act as a bridge from the psychological emotions of love to the physical and real emotions of man.

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.

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.

This note is concerned with Ned Block's claim that cognition differs from perception in being paradigmatically conceptual, propositional, and non-iconic. As against Block, it maintains that large stretches of cognition constitutively involve, or depend on, iconic representations.

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.
