Technological innovations have transformed our culture's ways of thinking about procreation and pregnancy, and about health and illness. Until not so long ago, the ongoing processes inside women's bodies as they gestated their future babies was up to conjecture. In Western industrialized countries, pregnancy was the slow process during which a woman gradually came to accept the fact that she was sharing her bodily space with another, and that now, as well as after the baby emerged, the primary responsibility for (...) that new person's survival would be hers.

The fission of a person involves what common sense describes as a single person surviving as two distinct people. Thus, say most metaphysicians, this paradox shows us that common sense is inconsistent with the transitivity of identity. Lewis’s theory of overlapping persons, buttressed with tensed identity, gives us one way to reconcile the common sense claims. Lewis’s account, however, implausibly says that reference to a person about to undergo fission is ambiguous. A better way to reconcile the claims of common (...) sense, one that avoids this ambiguity, is to recognize branching persons, persons who have multiple pasts or futures. (shrink)

This paper consists of two sections. In section one, I explore Val Plumwood's description of the features of normative dualism, and briefly discuss how these features are manifest in Immanuel Kant's view of nature. In section two, I evaluate the claims of Holly L. Wilson, who argues that Kant is not a normative dualist. Against Wilson, I will argue that Kant maintains normative dualisms between humans/nature, humans/animals, humans I culture, and men/women. As such, Kant's philosophy is antithetical to the aims (...) of ecofeminism, which seeks to expose and dismantle such dualistic thinking. (shrink)

Can different material objects have the same parts at all times at which they exist? This paper defends the possibility of such coincidence against the main argument to the contrary, the ‘Indiscernibility Argument’. According to this argument, the modal supervenes on the nonmodal, since, after all, the non-modal is what grounds the modal; hence, it would be utterly mysterious if two objects sharing all parts had different essential properties. The weakness of the argument becomes apparent once we understand how the (...) modal is grounded in the nonmodal. By extending the ideas of combinatorialism so that we recombine haecceities as well as fundamental properties, we see how modal properties can be grounded in non-modal properties in a way that allows coincidence and yet also explains why there are differences in the modal properties of coinciding objects. Despite this, some de re modal facts are not grounded in the non-modal but instead are brute. However, although we cannot explain why a particular object has the basic modal properties it has, we can explain a closely related, semantic fact and, comparing the facts we can’t explain to more familiar brute facts, we understand why there should be no better explanation. As a result, we can see how coincidence is, after all, possible. (shrink)

Challenging topics in museums can guide museum professionals in developing modern methods of displaying their heritage, but also in offering reinterpretations of existing collections. The public also looks for challenging topics—injustice, loss, pain, or death—and many museums manage to attract visitors by offering them places to debate, reflect, or take action. These topics, if presented in an exhibition, could engage practising artists in an ideological exchange with the museum institution. Our statement is that artists with curatorial interest can scrutinise the (...) ways in which cultural heritage is revealed or interpreted for the contemporary public. The uncomfortable or uncertain aspects of recent and contemporary history are of great interest for contemporary artists and we assume that the Communist era in Romania could be further interpreted by artists in future museum places.

Kim argues that weak and global supervenience are too weak to guarantee any sort of dependency. Of the three original forms of supervenience, strong, weak, and global, each commonly wielded across all branches of philosophy, two are thus cast aside as uninteresting or useless. His arguments, however, fail to appreciate the strength of weak and global supervenience. I investigate what weak and global supervenience relations are functionally and how they relate to strong supervenience. For a large class of properties, weak (...) and global supervenience are equivalent to strong supervenience. I then offer a series of arguments showing that it is precisely because of their strength, not their weakness, that both weak and global supervenience are useless in characterizing any dependencies of interest to philosophers.

The Moral Life: Obligation and Affirmation examines the broad scope of moral thought and behavior over the centuries. Moyers considers the notion of morals from various perspectives, asking: if everything is a matter of interpretation and morality is not written in stone, then how should we live?

A radical metaphysical theory typically comes packaged with a semantic theory that reconciles those radical claims with common sense. The metaphysical theory says what things exist and what their natures are, while the semantic theory specifies, in terms of these things, how we are to interpret everyday language. Thus may we “think with the learned, and speak with the vulgar.” This semantic accommodation of common sense, however, can end up undermining the very theory it is designed to protect. This paper (...) is a case study, showing in detail how one popular version of temporal parts theory is self-undermining. This raises the specter that the problem generalizes to other metaphysical theories. (shrink)

This article supplements our earlier paper on synaesthesia published in JCS (Ramachandran & Hubbard, 2001a). We discuss the phenomenology of synaesthesia in greater detail, raise several new questions that have emerged from recent studies, and suggest some tentative answers to these questions.

Ecologically valid procedures for eliciting and measuring children's anger are needed to enhance researchers' theories of children's emotional competence and to guide intervention efforts aimed at reactive aggression. The purpose of this article is to describe a laboratory-based game-playing procedure that has been used successfully to elicit and measure children's anger across observational, physiological, and self-report channels. Steps taken to ensure that participants are treated ethically and fairly are discussed. The article highlights recently published data that emphasize the importance of (...) provoking and assessing children's anger across multiple channels using laboratory-based procedures. Finally, it presents preliminary data that suggest that the safeguards taken to protect children were successful in making both children and their parents feel well treated and comfortable. (shrink)

In 1566 and 1567, two noted Florentine humanists–—Vincenzio Borghini and Girolamo Mei— carried on a written debate about Florence's origins and early history. That debate reveals significant features and innovations about the ways late humanists approached and employed historical evidence, as well as their own reflections on their methods. We see important roles for both humanistic tools of textual and linguistic analysis, and for antiquarian studies of artifacts and inscriptions. Borghini won the debate, but Mei remained committed to his own (...) emphasis on textual analysis and never accepted Borghini's broad and more eclectic use of artifacts as historical sources.

The consequences of a trend to marginalize social studies in the early grades are complex and widespread, as a new wave of novice teachers and K-6 students are receiving a message clearly implying that social studies education is unimportant. Convincing them of the value in teaching and learning social studies is progressively becoming more difficult for social studies methods instructors. The purpose of this study was to examine pre-service teachers’ observations of the extent to which social studies is being marginalized, (...) possible barriers involved, and the impact that this phenomenon has on pre-service teachers and K-6 students in the classroom. Through a mixed-method design, 88 pre-service teachers were asked to report their classroom observations. Over half observed social studies instruction. Of those who observed social studies instruction, about a third indicated that teachers taught 5–15 min per day. Pre-service teachers reported personal success in planning and teaching social studies lessons during their practicum experiences; likewise, K-6 students were motivated by pre-service teachers’ student-centered activities in the lessons. The results of this study provide one form of current documentation regarding the effects of social studies marginalization in K-6 schools. (shrink)

Experiences of qualia, subjective sensory-like aspects of stimuli, are central to imagistic representation. Following Raffman , qualia are considered to reflect experiential knowledge distinct from descriptive, abstract, and propositional knowledge; following Jackendoff , objective neural activity is distinguished from subjective experience. It is argued that descriptive physical knowledge does not provide an adequate accounting of qualia, and philosophical scenarios such as the Turing test and the Chinese Room are adapted to demonstrate inadequacies of accounts of cognition that ignore subjective experience. (...) Arguments by Dennett and others that qualia do not exist or that qualia do not provide additional explanatory power are addressed, and it is suggested that consideration of qualia is necessary in order to explain objective behavior. The hypotheses of functional equivalence, second-order isomorphism, and psychophysical complementarity between imagery and perception are discussed, and the ability of analog and schematic models of imagery to account for qualia is examined.

For those who think the statue and the piece of copper that compose it are distinct objects that coincide, there is a burden of explanation. After all, common sense says that different ordinary objects cannot occupy the same space at the same time. A common argument in favour of four-dimensionalism (or ?perdurantism? or ?temporal parts theory?) is that it provides the resources for a superior explanation of this coincidence. This, however, is mistaken. Any explanatory work done by the four-dimensionalist notion (...) of absolute parthood rests ultimately on notions equally available to the three-dimensionalist. Thus, a neutral explanation of coincidence is at least as good while avoiding commitment to temporal parts. ?Many thanks to David Christensen, Louis deRosset, Matti Eklund, and two anonymous referees for helpful comments.

We studied two otherwise normal, synaesthetic subjects who `saw' a speci¢c colour every time they saw a speci¢c number or letter. We conducted four experiments in order to show that this was a genuine perceptual experience rather than merely a memory association. (i)The synaesthetically induced colours could lead to perceptual grouping, even though the inducing numerals or letters did not. (ii)Synaesthetically induced colours were not experienced if the graphemes were presented peripherally. (iii)Roman numerals were ine¡ective: the actual number grapheme was (...) required. (iv)If two graphemes were alternated the induced colours were also seen in alternation. However, colours were no longer experienced if the graphemes were alternated at more than 4 Hz. We propose that grapheme colour synaesthesia arises from `cross-wiring' between the `colour centre' (area V4 or V8)and the `number area', both of which lie in the fusiform gyrus. We also suggest a similar explanation for the representation of metaphors in the brain: hence, the higher incidence of synaesthesia among artists and poets. (shrink)

Philosophers are apt to assume that impartial thinking is both possible and desirable. This article, originating in a very definite doubt of this assumption, is an attempt at an examination of the problem.

The ArgumentDuring the later European Renaissance, some scholars began to write about the history of scientific disciplines. Some of the issues and problems they faced in constructing their narratives have had long-term effects on the history of science. One of these issues was how to relate scholars from the Islamic traditions of scientific scholarship to those of antiquity and of postclassical Europe. Recent historians of science have rejected a once-common Western opinion that the contribution of these Islamic scientists had lain (...) mainly in their preservation of ancient texts that were then handed over to Western scholars, who mastered them and then moved beyond them as part of the scientific revolution. This article examines the first effort to write a history of mathematics, theLives of the Mathematiciansby Bernardino Baldi (1553–1617), to determine how he treated this issue in his work. Baldi's efforts are especially important here because he was also an early European scholar of Arabic.An examination of the work shows that Baldi did not share the negative views held by later Europeans about these non-European scientists. However, despite his knowledge of Arabic he had no active contacts with ongoing mathematical scholarship in Arabic. As a consequence, his narrative does follow the chronology of those later Europeans who would limit consideration of these mathematicians to approximately the ninth to the fourteenth centuries. In Baldi's writings, then, we can see the later narrative shape used by Western historians of science until recent years, but not the subsidiary role accorded to non-European scholars. (shrink)

Through an interdisciplinary approach, this book explores premodern, modern, and postmodern moral perspectives to identify the problems and challenges facing moral thinking in the 1990's and beyond.

The empirical literature on phenomenal causality (i.e., the notion that causality can be perceived) is reviewed. In Part I of this two-part series, different potential types of phenomenal causality (launching, triggering, reaction, tool, entraining, traction, braking, enforced disintegration and bursting, coordinated movement, penetration, expulsion) are described. Stimulus variables (temporal gap, spatial gap, spatial overlap, direction, absolute velocity, velocity ratio, trajectory length, radius of action, size, motion type, modality, animacy) and observer variables (attention, eye movements and fixation, prior experience, intelligence, age, (...) culture, psychopathology) that influence phenomenal causality are reviewed. This provides the necessary background for consideration in Part II (Hubbard, in press) of broader questions regarding properties of phenomenal causality, empirical and theoretical connections of phenomenal causality to other perceptual or cognitive phenomena or processes, and potential mechanisms and models of phenomenal causality.

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)

In this commentary we discuss a predictive sensorimotor illusion, the size-weight illusion, in which the smaller of two objects of equal weight is perceived as heavier. We suggest that Grush's emulation theory can explain this illusion as a mismatch between predicted and actual sensorimotor feedback, and present preliminary data suggesting that the cerebellum may be critical for implementing the emulator.
