This paper evaluates and criticises the developmental systems conception of evolution and develops instead an extension of the gene's eye conception of evolution. We argue (i) Dawkin's attempt to segregate developmental and evolutionary issues about genes is unsatisfactory. On plausible views of development it is arbitrary to single out genes as the units of selection. (ii) The genotype does not carry information about the phenotype in any way that distinguishes the role of the genes in development from that other factors. (...) (iii) There is no simple and general causal criterion which distinguishes the role of genes in development and evolution. (iv) There is, however, an important sense in which genes but not every other developmental factor represent the phenotype. (v) The idea that genes represent features of the phenotype forces us to recognise that genes are not the only, or almost the only, replicators. Many mechanisms of replication are involved in both development and evolution. (vi) A conception of evolutionary history which recognises both genetic and non-genetic replicators, lineages of replicators and interactors has advantages over both the radical rejection of the replicator/interactor distinction and the conservative restriction of replication to genetic replication.

In this paper, I argue that the adaptive fit between human cultures and their environment is persuasive evidence that some form of evolutionary mechanism has been important in driving human cultural change. I distinguish three mechanisms of cultural evolution: niche construction leading to cultural group selection; the vertical flow of cultural information from parents to their children, and the replication and spread of memes. I further argue that both cultural group selection and the vertical flow of cultural information have been (...) important. More conjecturally, I identify a potential role for meme-based cultural evolution in the explanation of the ‘human revolution’ of the last 100 000 or so years, and defuse an important objection to that explanation. Introduction Cultural groups The cultural invention of adaptive complexes Niche construction models Dual inheritance Memes Memes or minds? Conclusion. (shrink)

The International Research library of Philosophy collects in book form a wide range of important and influential essays in philosophy, drawn predominantly from English language journals. Each volume in the library deals with a field of enquiry which has received significant attention in philosophy in the last 25 years and is edited by a philosopher noted in that field.

The aim of the present study was to investigate the association between work-related moral stress, moral climate and moral sensitivity in mental health nursing. By means of the three scales Hospital Ethical Climate Survey, Moral Sensitivity Questionnaire and Work-Related Moral Stress, 49 participants’ experiences were assessed. The results of linear regression analysis indicated that moral stress was determined to a degree by the work place’s moral climate as well as by two aspects of the mental health staff’s moral sensitivity. The (...) nurses’ experience of ‘moral burden’ or ‘moral support’ increased or decreased their experience of moral stress. Their work-related moral stress was determined by the job-associated moral climate and two aspects of moral sensitivity. Our findings showed an association between three concepts: moral sensitivity, moral climate and moral stress. Despite being a small study, the findings seem relevant for future research leading to theory development and conceptual clarity. We suggest that more attention be given to methodological issues and developing designs that allow for comparative research in other disciplines, as well as in-depth knowledge of moral agency.

Jackson says that the form of physicalism that I recommend, with certain emendations he believes are necessary, turns out to be none other than the “Australian” type-type identity theory of J.J.C. Smart and others. About this, too, I have no serious disagreement, although Jackson’s claim appears to depend, at least in part, on a certain chosen reading of the texts involved. In fact, one point of similarity may be worth noting. As I take it, one special feature of the “Australian” (...) type identity theory is the claim that mental-physical identities are contingent, not necessary. Suppose M has a single physical realizer, P. On my account, the statement that M = P is not metaphysically or logically necessary. It is contingent since the statement that P realizes M is contingent. This is so because for P to realize M is for it to fulfill the causal specification that defines M, and what causal relations P actually enters into is a question that depends on the laws prevailing in a given world. Thus, P may be a realizer of M in this world but perhaps not in another in which different laws hold; in some worlds M may have no realizers at all. None of this is in violation of the idea that identities are necessary. For, according to me, if M has realizers, M is a functional property defined by a causal specification. This means that “M” is not a rigid designator, though it is, as we might call it, “nomologically rigid” or “semi-rigid”. (shrink)

In this paper I consider the view that scientific change is the result of a selection process which has the same structure as that which drives natural selection. I argue that there are important differences between organic evolution and scientific growth. First, natural selection is much more constrained than scientific change; for example it is hard to populations of organisms to escape local maxima. Science progresses; it may not even make sense to say that biological evolution is progressive. Second, natural (...) selection depends for its power on the specifics of its domain, so I doubt that there is much point in seeing a selective regime in science as an instance of a more general family of selective regimes. Third, the replicator/interactor distinction fits scientific change much less well than biological evolution. But a family of selective theories of science can be identified ranging from the very ambitious to the very modest. Though the very ambitious programs of evolutionary epistemology are in trouble, there is space for one which is not a trivial redescription of what everyone already knows, but which is sensitive to the peculiarities of its domain. That selective theory explains important aspects of the community organization of science, an organization which is central to scientific progress. (shrink)

ABSTRACT:We argue that Confucianism makes a fundamental contribution to understanding why civility is necessary for a morally decent workplace. We begin by reviewing some limits that traditional moral theories face in analyzing issues of civility. We then seek to establish a Confucian alternative. We develop the Confucian idea that even in business, humans may be sacred when they observe rituals culturally determined to express particular ceremonial significance. We conclude that managers and workers should understand that there is a broad range (...) of morally important rituals in organizational life and that managers should preserve and develop the intelligibility and integrity of many of these rituals.

The acquisition of English noun and verb morphology is modeled using a single-system connectionist network. The network is trained to produce the plurals and past tense forms of a large corpus of monosyllabic English nouns and verbs. The developmental trajectory of network performance is analyzed in detail and is shown to mimic a number of important features of the acquisition of English noun and verb morphology in young children. These include an initial error-free period of performance on both nouns and (...) verbs followed by a period of intermittent over-regularization of irregular nouns and verbs. Errors in the model show evidence of phonological conditioning and frequency effects. Furthermore, the network demonstrates a strong tendency to regularize denominal verbs and deverbal nouns and masters the principles of voicing assimilation. Despite their incorporation into a single-system network, nouns and verbs exhibit some important differences in their profiles of acquisition. Most importantly, noun inflections are acquired earlier than verb inflections. The simulations generate several empirical predictions that can be used to evaluate further the suitability of this type of cognitive architecture in the domain of inflectional morphology. (shrink)

In this paper, we study the notions related to tree property 1 , or, equivalently, SOP2. Among others, we supply a type-counting criterion for TP1 and show the equivalence of TP1 and k- TP1. Then we introduce the notions of weak k- TP1 for k≥2, and also supply type-counting criteria for those. We do not know whether weak k- TP1 implies TP1, but at least we prove that each weak k- TP1 implies SOP1. Our generalization of the tree-indiscernibility results in (...)

Background:Despite the growing body of knowledge about surrogate decision making, we know very little about the use of ethical frameworks (including ethical theories, principles, and concepts) to understand surrogates’ day-to-day experiences in end-of-life care planning for incapacitated adults.Objectives and Methods:This qualitative systematic review was conducted to identify the types of ethical frameworks used to address surrogates’ experiences in end-of-life care planning for incapacitated adults as well as the most common themes or patterns found in surrogate decision-making research.Findings:Seven research papers explicitly (...) identified ethical theories, principles, or concepts, such as autonomy, substituted judgment, and best interest standards as guidelines for the research. Surrogate decision making themes included the responsibilities and goals of being a surrogate, factors influencing surrogates’ decision making, outcomes for surrogates, and an overarching theme of “wanting to do the right thing” for their loved one and/or themselves.Discussion:Understanding the complexity of surrogates’ experiences of end-of-life care planning is beyond the scope of conventional ethical frameworks.Conclusion:Ethical frameworks that address individuality and contextual variations related to decision making may more appropriately guide surrogate decision-making research that explores surrogates’ end-of-life care planning experiences.

Subjects enrolled in studies testing high risk interventions for incurable or progressive brain diseases may be vulnerable to deficiencies in informed consent, such as the therapeutic misconception. However, the definition and measurement of the therapeutic misconception is a subject of continuing debate. Our qualitative pilot study of persons enrolled in a phase I trial of gene transfer for Parkinson disease suggests potential avenues for both measuring and preventing the therapeutic misconception. Building on earlier literature on the topic, we developed and (...) tested an interview guide that focuses on how the subjects decided to participate, emphasizing the integration of subjects’ various statements that are relevant to assessing the therapeutic misconception, rather than evaluating them as isolated statements. The results indicate that a subject’s understanding of the purpose of research is best explored in juxtaposition to the subject’s motivation for participating. (shrink)

In this paper, I will defend modalfictionalism. The paper has two parts. In thefirst part, I will suggest a revised version ofmodal fictionalism which can avoid certaintechnical problems. In the second part, I willpropose a nominalized version of modalfictionalism and a general scheme offictionalism for the nominalist.

This descriptive study was undertaken to identify the degree of ethical sensitivity of staff nurses and to analyze the differences in ethical sensitivity in terms of both general and ethics-related characteristics. Participants were 236 staff nurses working in general hospitals in Korea. Ethical sensitivity was measured by means of an instrument developed by the researchers. The results showed that the mean score for the degree of ethical sensitivity was 0.71 out of a possible maximum score of 1 (range 0.30 to (...) 0.97). For general characteristics, there was a significant difference in ethical sensitivity according to age (F (df 2233)-3.99, P-0.02). For characteristics related to ethics, there was a significant difference in ethical sensitivity according to attitude towards the nursing profession (F (df 4231)-2.94, P-0.03). It is therefore recommended that a training program reflecting these variables be developed to enhance staff nurses’ ethical sensitivity. (shrink)

This paper is an exposition and defense of Kant’s philosophy of geometry. The main thesis is that Euclidean geometry investigates the properties of geometrical objects in an inner space that is given to us a priori (pure space) and hence is a priori and synthetic. This thesis is supported by arguing that Euclidean geometry requires certain intuitive objects (Sect. 1), that these objects are a priori constructions in pure space (Sect. 2), and finally that the role of geometrical construction is (...) to provide geometrical objects, not concepts, as some have claimed (Sect. 3).

While it is well known that Zhuangzi uses metaphor extensively, there is much less appreciation of the role that it plays in his thought-a topic that is investigated in this essay. At the same time, this investigation is closely concerned with questions about the nature of metaphor. Comparisons are made between a central metaphorical structure in the Zhuangzi on the one hand and contemporary views of the nature of metaphor by Donald Davidson and by Lakoff and Johnson on the other. (...) It is hoped that these comparisons will help to illuminate the central metaphorical structure and its role in the philosophy of the Zhuangzi. (shrink)

This paper examines the methodological problem of casuistry by reference to Immanuel Kant's position on it. He addressed “Casuistical Questions” in his last work on ethics, Metaphysik der Sitten, in order to defend his position against attacks from scholars defending an Aristotelian eudemonistic viewpoint. It is argued that Kantian casuistry has much in common with the Aristotelian idea of emphasizing the moral objectives and sensibility of an agent in concrete circumstances. Nevertheless, Kant did not entirely adopt the case-oriented ethical perspective (...) because he saw the moral duty as the „wide“ one. Moral duties are wide in the sense that they demand continuous self-examination: asking whether there might be a better way to limit one's maxim by another. According to Kant, although casuistry as a case study could give moral law or duties more practicability through the training of moral judgment, the moral agent cannot use with individual cases in order to modify or devise new moral rules or duties.

Less than one percent of U.S. philosophers are Asian American. This essay contends that the low percentage cannot be fully explained by considerations of demographics, immigration, and "Asian culture." Completeness of explanation requires reference to racial politics and Orientalism in their historic and national dynamics. It also requires reference to various kinds of identity derogation specific to the academy and to philosophy, in particular. The essay concludes with reflection on how the "model minority" discourse adds another layer of complication to (...) the way Asian American philosophers and philosophy students negotiate their way through the academy.

Frege’s argument against the ancient Greek conception of numbers as 'multitudes of units’ has been hailed as one of the most successful in his "Grundlagen". The aim of this paper is to show that despite Frege’s best efforts, the Euclidean conception remains a viable alternative to the Fregean conception of numbers by arguing that neither a dilemma argument Frege brings against the Euclidean conception nor a possible argument against it based on the truth of what is known as "Hume’s Principle" (...) succeeds.

This paper argues that (cardinal) numbers are originally given to us in the context ‘Fs exist n-wise’, and accordingly, numbers are certain manners or modes of existence, by addressing two objections both of which are due to Frege. First, the so-called Caesar objection will be answered by explaining exactly what kind of manner or mode numbers are. And then what we shall call the Functionality of Cardinality objection will be answered by establishing the fact that for any numbers m and (...) n, if there are exactly m Fs and also there are exactly n Fs, then m = n.

This longitudinal study examined how nursing students' moral judgment changes after they become qualified nurses working in a hospital environment. The sample used was a group of 80 nursing students attending a university in Suwon, Korea, between 2001 and 2003. By using a Korean version of the Judgment About Nursing Decisions questionnaire, an instrument used in nursing care research, moral judgment scores based on Ketefian's six nursing dilemmas were determined. The results were as follows: (1) the qualified nurses had significantly (...) higher idealistic moral judgment scores than the nursing students; (2) the qualified nurses showed significantly higher realistic moral judgment scores than the nursing students; and (3) when comparing idealistic and realistic moral judgment scores, both the qualified nurses and the nursing students had higher scores for idealistic moral judgment. Further study is recommended to examine changes in moral judgment. (shrink)

Somites are transient structures which represent the most overt segmental feature of the vertebrate embryo. The strict temporal regulation of somitogenesis is of critical developmental importance since many segmental structures adopt a periodicity based on that of the somites. Until recently, the mechanisms underlying the periodicity of somitogenesis were largely unknown. Based on the oscillations of c-hairy1 and lunatic fringe RNA, we now have evidence for an intrinsic segmentation clock in presomitic cells. Translation of this temporal periodicity into a spatial (...) periodicity, through somite formation, requires Notch signaling. While the Hox genes are certainly involved, it remains unknown how the metameric vertebrate axis becomes regionalized along the antero–posterior (AP) dimension into the occipital, cervical, thoracic, lumbar, and sacral domains. We discuss the implications of cell division as a clock mechanism underlying the regionalization of somites and their derivatives along the AP axis. Possible links between the segmentation clock and axial regionalization are also discussed. (shrink)

As humanoid social robots are developed rapidly in recent years and experimented in social situations, comparing them to humans provides insights into practical as well as philosophical concerns. This study uses the theoretical framework of communication constraints, derived in human–human communication research, to compare whether people apply social-oriented constraints and task-oriented constraints differently to human targets versus humanoid social robot targets. A total of 230 students from the University of Hawaii at Manoa participated in the study. The participants completed a (...) questionnaire, which determined their concern for the five communication constraints (feelings, non-imposition, disapproval, clarity, and effectiveness) in situations involving humans or robots. The results show people were more concerned with avoiding hurting the human’s feelings, avoiding inconveniencing the human interactive partner, and avoiding being disliked by the human and less concerned with avoiding hurting the robot’s feelings, avoiding inconveniencing the robot partner, and avoiding being disliked by the robot. But people did not differ in their concerns of the two task-oriented constraints (clarity and effectiveness) in response to humans versus humanoid robots. The results of the research suggest that people are more likely to emphasize the social-oriented constraints in communication with humans. (shrink)

The term “legacy effect” has been used in ecology since the early 1990s by authors studying plant succession, invasive-plant impacts, herbivory impacts, ecosystem engineering, and human land-use impacts. Although there is some variability in usage, the term is normally used to describe impacts of a species on abiotic or biotic features of ecosystems that persist for a long time after the species has been extirpated or ceased activity and which have an effect on other species. For example, human agricultural activities (...) may have a legacy effect on soil structure and vegetative communities that lasts for centuries and which alters current communities. The concept may be related to the idea of ecological inheritance in evolutionary biology but would refer only to a subset of the features of this concept. In particular, legacy effects could refer to those kinds of ecological inheritance where a physical or biological change in ecosystem state is caused by one species, where this change persists after the extirpation of the causal species and alters selection pressure of another species much later in time.

In this article, I explore an alternative model of Confucian distributive justice, namely the ‘family model’, by challenging the central claim of recent sufficientarian justifications of Confucian justice offered by Confucian political theorists – roughly, that inequalities of wealth and income beyond the threshold of sufficiency do not matter if they reflect different merits. I argue (1) that the telos of Confucian virtue politics – moral self-cultivation and fiduciary society – puts significant moral and institutional constraints on inequality even if (...) it meets the threshold of sufficiency and largely results from differing individual merits; (2) that the Confucian moral ideal of the family state establishes and gives justification to the ‘family model’ of distributive justice that shifts the focus from desert to vulnerability and from causal responsibility to remedial responsibility. The article concludes by presenting Confucian democracy as the socio-political institution and practice that can best realize the Confucian intuition of the family model of justice. (shrink)

In this article I argue that in H 6 Aristotle's main concern is to explain both the unity of form and the unity of composite substance. Commentators have taken H 6 as concerned with either the unity of form or the unity of the composite substance, but not with both. But there is no exclusive "either/or". The correct position is "both/and". I argue that proper identification of the aim of the inquiry of H 6 indicates that Aristotle is concerned with (...) both the unity of form and the unity of composite substance. On my interpretation, Aristotle's intention is to defend the theory of substance-as-cause by dealing with a possible problem. The possible problem arises from a combination of (a) speaking about the parts of form and the parts of composite substances and (b) the principle that parts of a whole need a unifying cause in order to be one and not many. Aristotle has (a') spoken about the parts of form and the parts of composite substance. He has also (b') claimed that the parts of a whole have to have a unifying cause in order to be one and not many. Do form and composite substance, then, have a unifying cause for their unity? Aristotle sees a possible problem arising from thinking that they do. If both form and composite particulars need a unifying cause, form cannot be substance, and composite substances, as composites of form and matter, cannot be unities, but must be mere heaps of matter. The problems of theunity of form and the unity of composite substance are similar, then; and the unity of each must be accounted for. Not surprisingly, the problems being similar, the solutions to those problems, the accounts of the unity of form and composite substance, are similar as well. The two are thus discussed together in H 6. It is there that Aristotle provides such accounts. H 6, then, concerns both the unity of form and the unity of composite substance. (shrink)
