We are immersed within an odorous sea of chemical currents that we parse into individual odors with complex structures. Odors have been posited as determined by the structural relation between the molecules that compose the chemical compounds and their interactions with the receptor site. But, naturally occurring smells are parsed from gaseous odor plumes. To give a comprehensive account of the nature of odors the chemosciences must account for these large distributed entities as well. We offer a focused review of (...) what is known about the perception of odor plumes for olfactory navigation and tracking, which we then connect to what is known about the role odorants play as properties of the plume in determining odor identity with respect to odor quality. We end by motivating our central claim that more research needs to be conducted on the role that odorants play within the odor plume in determining odor identity. (shrink)

Lexical Semantics is about the meaning of words. Although obviously a central concern of linguistics, the semantic behaviour of words has been unduly neglected in the current literature, which has tended to emphasize sentential semantics and its relation to formal systems of logic. In this textbook D. A. Cruse establishes in a principled and disciplined way the descriptive and generalizable facts about lexical relations that any formal theory of semantics will have to encompass. Among the topics covered in depth are (...) idiomaticity, lexical ambiguity, synonymy, hierarchical relations such as hyponymy and meronymy, and various types of oppositeness. Syntagmatic relations are also treated in some detail. The discussions are richly illustrated by examples drawn almost entirely from English. Although a familiarity with traditional grammar is assumed, readers with no technical linguistic background will find the exposition always accessible. All readers with an interest in semantics will find in this original text not only essential background but a stimulating new perspective on the field. (shrink)

At the risk of proving myself such a caviller, I want to ask a question which I have seldom heard raised, and which I have never seen discussed in anything that I have read about Berkeley. If I am right, it poses a problem for his immaterialism, not only different, but coming from a different direction, from those objections that are commonly levelled against him. If I am wrong, it will show how right Berkeley was to stress the difficulty of (...) using for one purpose our language which has become fashioned for another. At least, I hope that I shall not fail to be the ‘fair and ingenuous reader’for whom he asked. (shrink)

Revisiting African philosophy’s classic questions, D. A. Masolo advances understandings of what it means to be human—whether of African or other origin. Masolo reframes indigenous knowledge as diversity: How are we to understand the place and structure of consciousness? How does the everyday color the world we know? Where are the boundaries between self and other, universal and particular, and individual and community? From here, he takes a dramatic turn toward Africa’s current political situation and considers why individual rights and (...) freedoms have not been recognized, respected, demanded, or enforced. Masolo offers solutions for containing socially destructive conduct and antisocial tendencies by engaging community. His unique thinking about community and the role of the individual extends African philosophy in new, global directions. (shrink)

In debates about criteria for human death, several camps have emerged, the main two focusing on either loss of the "organism as a whole" (the mainstream view) or loss of consciousness or "personhood." Controversies also rage over the proper definition of "irreversible" in criteria for death. The situation is reminiscent of the proverbial blind men palpating an elephant; each describes the creature according to the part he can touch. Similarly, each camp grasps some aspect of the complex reality of death. (...) The personhood camp, in contrast to the mainstream "organism" camp, recognizes that a human organism can still be a biological living whole even without brain function. The mainstream camp, in contrast to the personhood camp, recognizes that a person can be permanently, even irreversibly unconscious, and still be a living person so long as his/her body is alive. The author proposes that hylomorphic dualism incorporates both these key insights. But to complete the picture of the entire "death elephant," a fundamental paradigm shift is needed to make sense of other seemingly conflicting insights. The author proposes a "semantic bisection" of the concept of death, analogous to the traditional distinction at the beginning of life between "conception" and "birth." To avoid the semantic baggage associated with the term "death," the two new death-related concepts are referred to as "passing away" (or "deceased") and "deanimation," corresponding, respectively, to sociolegal ceasing-to-be (mirror image of birth) and ontological/theological ceasing-to-be of the bodily organism (mirror image of conception). Regarding criteria, the distinguishing feature is whether the cessation of function is permanent (passing away) or irreversible (deanimation). If the "dead donor rule" were renamed the "deceased donor rule" (both acronyms felicitously being "DDR"), the ethics of organ transplantation from non–heart-beating donors could, in principle, be validly governed by the DDR, even though the donors are not yet ontologically "deanimated." Thus, the paradigm shift satisfies both those who insist on maintaining the DDR and those who claim that it has all along been receiving only lip service and should be explicitly loosened to include those who are "as good as dead." Even so, a number of practical caveats remain to be worked out for non–heart-beating protocols. (shrink)

In some languages every statement must contain a specification of the type of evidence on which it is based: for example, whether the speaker saw it, or heard it, or inferred it from indirect evidence, or learnt it from someone else. This grammatical reference to information source is called 'evidentiality', and is one of the least described grammatical categories. Evidentiality systems differ in how complex they are: some distinguish just two terms (eyewitness and noneyewitness, or reported and everything else), while (...) others have six or even more terms. Evidentiality is a category in its own right, and not a subcategory of epistemic or some other modality, nor of tense-aspect. Every language has some way of referring to the source of information, but not every language has grammatical evidentiality. In English expressions such as I guess, they say, I hear that, the alleged are not obligatory and do not constitute a grammatical system. Similar expressions in other languages may provide historical sources for evidentials. True evidentials, by contrast, form a grammatical system. In the North Arawak language Tariana an expression such as "the dog bit the man" must be augmented by a grammatical suffix indicating whether the event was seen, or heard, or assumed, or reported. This book provides the first exhaustive cross-linguistic typological study of how languages deal with the marking of information source. Examples are drawn from over 500 languages from all over the world, several of them based on the author's original fieldwork. Professor Aikhenvald also considers the role evidentiality plays in human cognition, and the ways in which evidentiality influences human perception of the world.. This is an important book on an intriguing subject. It will interest anthropologists, cognitive psychologists and philosophers, as well as linguists. (shrink)

A three-valued propositional logic is presented, within which the three values are read as ?true?, ?false? and ?nonsense?. A three-valued extended functional calculus, unrestricted by the theory of types, is then developed. Within the latter system, Bochvar analyzes the Russell paradox and the Grelling-Weyl paradox, formally demonstrating the meaninglessness of both.

Migrations driven by ethnic, religious, and other forms of social conflict have been common in the past quarter-century, and have in Africa led many to seek refuge and to expect hospitality abroad. This leads to a concern for pluralist ethics, for many receiving refuge abroad expect that they will be able to live by their thoughts and beliefs, creating enclaves of cultural difference. But difference exists in all communities: cultural homogeneity does not exist except in the conservative imagination. Nevertheless, a (...) sameness – the sameness of the value of every person – remains within this plurality. The sameness is conceived in distinct ways in the Natural Law tradition that yields liberalism, in the Golden Rule, in Kant's categorical imperative, and in the Luo culture of Eastern Africa. The Luo precept Luoro remb dhano is compared with these other ethical cosmopolitan wellsprings in this essay. (shrink)

The following article is a response to the position paper of the Hastings Center, “Ethical Challenges of Chronic Illness”, a product of their three year project on Ethics and Chronic Care. The authors of this paper, three prominent bioethicists, Daniel Callahan, Arthur Caplan, and Bruce Jennings, argue that there should be a different ethic for acute and chronic care. In pressing this distinction they provide philosophical grounds for limiting medical care for the elderly and chronically ill. We give a critical (...) survey of their position and reject it as well as any attempt to characterize the physician-patient relationship as a commercial contract. We emphasize, as central features of good medical practice, a commitment to be the patient's agent and a determination to acquire and be guided by knowledge. These commitments may sometimes conflict with efforts to have the physician serve as an instrument of social and economic policies limiting medical care. (shrink)

Physicians have developed a number of implicit and explicit approaches to complex medical decisions. Decision analysis is an explicit, quantitative method of clinical decision making that involves the separation of the probabilities of events from their relative values, or utilities. Its use can help physicians make difficult choices in a manner that promotes true patient participation. Decision analysis also provides a framework for the incorporation of data from multiple sources and for the assessment of the impact of uncertain data on (...) the final decision. Although this approach is imperfect, it represents a significant advance in clinical decision making. (shrink)

The Kenya-born philosopher Henry Odera Oruka (1944 - 1995) persistently, and consistently, made proposals for a different moral approach to addressing, and possibly solving, some of the root causes of human conflicts across the world. I will call it “taking suffering seriously” as the basis of his idea of a global-level collective justice which, for him, raised the idea of the ethics of care to the level of global justice. I propose in this paper to show that this concern can (...) be found to be pervasive in Oruka’s works, connecting many of his well known positions as well as less known ones, and to discuss its philosophical merits.

Traditional explanations of multistable visual phenomena (e.g. ambiguous figures, perceptual rivalry) suggest that the basis for spontaneous reversals in perception lies in antagonistic connectivity within the visual system. In this review, we suggest an alternative, albeit speculative. explanation for visual multistability - that spontaneous alternations reflect responses to active, programmed events initiated by brain areas that integrate sensory and non-sensory information to coordinate a diversity of behaviors. Much evidence suggests that perceptual reversals are themselves more closely related to the expression (...) of a behavior than to passive sensory responses: (1) they are initiated spontaneously, often voluntarily, and are influenced by subjective variables such as attention and mood; (2) the alternation process is greatly facilitated with practice and compromised by lesions in non- visual cortical areas; (3) the alternation process has temporal dynamics similar to those of spontaneously initiated behaviors; (4) functional imaging reveals that brain areas associated with a variety of cognitive behaviors are specifically activated when vision becomes unstable. In this scheme, reorganizations of activity throughout the visual cortex, concurrent with perceptual reversals, are initiated by higher, largely non- sensory brain centers. Such direct intervention In the processing of the sensory input by brain structures associated with planning and motor programming might serve an important role in perceptual organization, particularly in aspects related to selective attention.
