The target article emphasizes the need to identify psychological mechanisms underlying grandparental investment, particularly in low-risk family contexts. We extend this approach by addressing the changing demands of balancing work and family in low-risk families. Taking a lifespan psychological perspective, we identify additional motivators and potential benefits of grandparental investment for grandparents themselves and for subsequent generations.

We address two main issues: the distinction between time-constrained and spatially constrained tasks, and the separable A and W effects on movement time (MT) in spatially-constrained tasks. We consider MT and 3-D kinematic data from human adults pointing to targets in human-computer interaction. These are better fit by Welford's (1968) two-part model, than Fitts' (1954; Fitts & Peterson 1964) ID model. We identify theoretical and practical implications.

The norm of assertion, to be in force, is a social norm. What is the content of our social norm of assertion? Various linguistic arguments purport to show that to assert is to represent oneself as knowing. But to represent oneself as knowing does not entail that assertion is governed by a knowledge norm. At best these linguistic arguments provide indirect support for a knowledge norm. Furthermore, there are alternative, non-normative explanations for the linguistic data (as in recent work from (...) Van Elswyk). Direct arguments would rely on normative judgments about the permissibility or impermissibility of assertions with and without the speaker knowing the content asserted. John Turri's work experimental results purport to show that our norm of assertion is factive, and probably knowledge. But as a number of recent experimentalists (Kneer, Reuter and Broessel, Marsili and Wiegmann) have shown, Turri's results rely on the problemmatic use of 'should' as in 'Maria should assert that she owns a 1990 watch.' Correcting for this, these experimentalists provide strong evidence that our norm of assertion is not factive. The standard reply to evidence like this from the assertion of unlucky falsehoods is the excuse maneuver. But Marsili and Wiegmann, following Turri's protocol for testing for excuse validation, show that participants who judge that assertions unlucky falsehoods are permissible are not guilty of excuse validation. Given our current understanding of the experimental evidence, knowledge is not our norm of assertion. (shrink)

Most phobias are focussed on a small number of fear-inducing stimuli (e.g., snakes, spiders). A review of the evidence supporting biological and cognitive explanations of this uneven distribution of phobias suggests that the readiness with which such stimuli become associated with aversive outcomes arises from biases in the processing of information about threatening stimuli rather than from phylogenetically based associative predispositions or “biological preparedness.” This cognitive bias, consisting of a heightened expectation of aversive outcomes following fear-relevant stimuli, generates and maintains (...) robust learned associations between them. Some of the features of such stimuli which determine this expectancy bias are estimates of how dangerous they are, the semiotic similarity between them and their aversive outcomes, and the degree of prior fear they elicit. Ontogenetic and cultural factors influence these features of fear-relevant stimuli and are hence important in determining expectancy bias. The available evidence does not exclude the possibility that both expectancy biases and specific evolved predispositions coexist, but the former can explain a number of important findings that the latter cannot.

Recent studies of spider phobia have indicated thatfearof spiders is closely associated with the disease-avoidance response of disgust. It is argued that the disgust-relevant status of the spider resulted from its association with disease and illness in European cultures from the tenth century onward. The development of the association between spiders and illness appears to be linked to the many devastating and inexplicable epidemics that struck Europe from the Middle Ages onwards, when the spider was a suitable displaced target for (...) the anxieties caused by these epidemics. Such factors suggest that the pervasive fear of spiders that is commonly found in many Western societies may have cultural rather than biological origins, and may be restricted to Europeans and their descendants.

A proper evaluation of the biological significance of Pavlovian conditioning requires consideration of performance mechanisms. Domjan et al.'s definition of net benefit is simplistic, and their model promotes convergence in behaviour, ignoring the possibility of innovation.

In his book "Organic Chemistry in its Application to Agriculture and Chemistry." Justus Liebig attacked "the plant physiologists" for their support of the humus theory and for their general ignorance of chemistry. Two leading botanists, Matthias Schleiden and Hugo von Mohl, responded by sharply criticizing Liebig for his lack of knowledge of plants and his misrepresentation of the views of plant physiologists. The origin and character of this debate can be understood in part through the temperaments of Liebig and Schleiden, (...) but can be viewed also as a contest for control between the well-established discipline of chemistry and a potential discipline of plant physiology that had as yet acquired no stable institutional foundations.

A series of arguments are presented by De Jong & Merckelbach which suggest that biological preparedness has been received significantly less critically than it should have been. I agree fully with their assessment. Cuthbert raises four questions about the applicability of the expectancy bias hypothesis to selective associations in human conditioning. This response argues that none of these four examples is necessarily problematic for the hypothesis.

This special volume of Studies in Christian Ethics constitutes the most significant continuation to date of Christian social ethics in the tradition of Ronald Preston. It brings together leading scholars and new voices in the field from around the world, covering a broad range of contemporary issues, including globalisation, poverty, feminism, civil society, economics and religious pluralism.

"Paradox drives a good deal of philosophy in every tradition. In the Indian and Western traditions, there is a tendency among many philosophers to run from contradiction and paradox. If and when a contradiction appears in a theory, it is regarded as a sure sign that something has gone amiss. This aversion to paradox commits them, knowingly or not, to the view that reality must be consistent. In East Asia, however, philosophers have reacted to paradox differently. Many East Asian philosophers-both (...) in the Daoist and the Buddhist traditions-have openly embraced paradox. They have taken compelling arguments for contradictory positions to suggest that the world is-at least in some respects, and often in very deep respects-inconsistent, and that our best theories of the world will therefore be inconsistent. This book is an initial survey of the writings of some influential East Asian thinkers who were committed to paradox, and for good reason. Their acceptance of contradiction allowed them to develop important insights that evaded those who consider paradox out of bounds"--. (shrink)

The argument from fine tuning is supposed to establish the existence of God from the fact that the evolution of carbon-based life requires the laws of physics and the boundary conditions of the universe to be more or less as they are. We demonstrate that this argument fails. In particular, we focus on problems associated with the role probabilities play in the argument. We show that, even granting the fine tuning of the universe, it does not follow that the universe (...) is improbable, thus no explanation of the fine tuning, theistic or otherwise, is required.

In his article in this issue, " 'How do Mādhyamikas Think?' Revisited," Tom Tillemans reflects on his earlier article "How do Mādhyamikas Think?" (2009), itself a response to earlier work of ours (Deguchi et al. 2008; Garfield and Priest 2003). There is much we agree with in these non-dogmatic and open-minded essays. Still, we have some disagreements. We begin with a response to Tillemans' first thoughts, and then turn to his second thoughts.Tillemans (2009) maintains that it is wrong to attribute (...) to Nāgārjuna or to his Mādhyamika followers a strong dialetheism, according to which some contradictions of the form p ∧ ¬p are to be accepted. He argues that, nonetheless, a weak dialetheism may be implicit in the .. (shrink)

Logical Options introduces the extensions and alternatives to classical logic which are most discussed in the philosophical literature: many-sorted logic, second-order logic, modal logics, intuitionistic logic, three-valued logic, fuzzy logic, and free logic. Each logic is introduced with a brief description of some aspect of its philosophical significance, and wherever possible semantic and proof methods are employed to facilitate comparison of the various systems. The book is designed to be useful for philosophy students and professional philosophers who have learned some (...) classical first-order logic and would like to learn about other logics important to their philosophical work.

This paper draws attention to the role of representation in the depiction of scientific and technological innovation as a means of understanding the narratives that circulate concerning the shape of things to come. It considers how metaphors play an important part in the conduct of scientific explanation, and how they do more than describe the world in helping also to shape expectations, normalise particular choices, establish priorities and create needs. In surveying the range of metaphorical responses to the digital and (...) biotechnological age, we will see how technologies are regarded both as 'endangerment' and 'promise'. What we believe 'technology' is doing to 'us' reflects important implicit philosophies of technology and its relationship to human agency and political choice; yet we also need to be alert to the assumptions about 'human nature' itself which inform such reactions. The paper argues that embedded in the various representations implicit in new technologies are crucial issues of identity, community and justice: what it means to be (post)human, who is (and is not) entitled to the rewards of technological advancement, what priorities (and whose interests) will inform the shape of global humanity into the next century.

: Nagarjuna seems willing to embrace contradictions while at the same time making use of classic reductio arguments. He asserts that he rejects all philosophical views including his own-that he asserts nothing-and appears to mean it. It is argued here that he, like many philosophers in the West and, indeed, like many of his Buddhist colleagues, discovers and explores true contradictions arising at the limits of thought. For those who share a dialetheist's comfort with the possibility of true contradictions commanding (...) rational assent, for Nagarjuna to endorse such contradictions would not undermine but instead confirm the impression that he is indeed a highly rational thinker. It is argued that the contradictions he discovers are structurally analogous to many discovered by Western philosophers and mathematicians. (shrink)

This mixed methods study examines how college students’ perceptions and experiences affect their understanding of academic integrity. Using qualitative and quantitative responses from the Personal and Social Responsibility Institutional Inventory, both quantitative and qualitative results demonstrate that while campuses may see a reduction in overall levels of cheating when punitive academic integrity policies are present, students may develop higher levels of personal and academic integrity through the use of more holistic and community-focused practices.

If you want to understand McDowell's spatial metaphors when he talks about perceptual knowledge, place him side-by-side with Dretske on perceptual knowledge. Though McDowell shows no evidence of reading Dretske's writings on knowledge from the late 1960s onwards (McDowell mentions "Epistemic Operators" once in passing), McDowell gives the same four arguments as Dretske for the conclusion that knowledge requires "conclusive" reasons that rule of the possibility of mistake. Despite various differences, we think it is best to read McDowell as re-discovering (...) Dretske on perceptual knowledge. Since Dretske is easy to understand, all of McDowell's metaphors become easy to understand. But what about McDowell's disjunctivism? Turns out McDowell is not an ontological disjunctivist, and his epistemological disjunctivism is really just the banal point that some perceptual experiences provide conclusive reasons for perceptual belief and some do not. Perceptual experiences are either conclusive or inconclusive. Dretske would agree. (shrink)

In this issue, Constance Kassor describes Gorampa's attitude to contradictions as they occur in various contexts of Buddhist pursuit. We agree with much of what she says; with some things we do not.First, some preliminary comments, and a fundamental disagreement. Kassor says:Based on . . . [the assumption that Nāgārjuna has a coherent system of thought] one must resolve apparent contradictions in Nāgārjuna's texts in order to maintain the coherency of his logic. The problem with contradictions is that if they (...) are introduced into a classical logical system, that entire system can break down. This is because of the law of explosion—the principle that everything can follow [DGP: does follow] from a contradiction.One .. (shrink)

The advent of formal definitions of the simplicity of a theory has important implications for model selection. But what is the best way to define simplicity? Forster and Sober ([1994]) advocate the use of Akaike's Information Criterion (AIC), a non-Bayesian formalisation of the notion of simplicity. This forms an important part of their wider attack on Bayesianism in the philosophy of science. We defend a Bayesian alternative: the simplicity of a theory is to be characterised in terms of Wallace's Minimum (...) Message Length (MML). We show that AIC is inadequate for many statistical problems where MML performs well. Whereas MML is always defined, AIC can be undefined. Whereas MML is not known ever to be statistically inconsistent, AIC can be. Even when defined and consistent, AIC performs worse than MML on small sample sizes. MML is statistically invariant under 1-to-1 re-parametrisation, thus avoiding a common criticism of Bayesian approaches. We also show that MML provides answers to many of Forster's objections to Bayesianism. Hence an important part of the attack on Bayesianism fails. (shrink)

Dōgen Kigen (1200–1253 ce) is one of the most revered figures in the history of Japanese culture. A Zen master regarded by the Sōtō School as its spiritual founder, Dōgen is also considered by many to be Japan's greatest philosopher. (The other major contender is kūkai, with whose philosophy Dōgen's shares a number of features.) Possessed of a prodigious and subtle intellect, and master of a strikingly poetic style, he surely ranks among the world's most formidable thinkers.

Most accounts of integrity agree that the person of integrity must have a relatively stable sense of who he is, what is important to him, and the ability to stand by what is most important to him in the face of pressure to do otherwise. But does integrity place any constraints on the kind of principles that the person of integrity stands for? In response to several recent accounts of integrity, I argue that it is not enough that a person (...) stand for what he believes in, nor even that he is committed to and stands for what, in his best judgement, is morally right. In our web of moral concepts integrity is internally related to a host of virtues which exclude weakness of will and dogmatism, and presuppose trustworthiness. Integrity requires that the principles stood for must be those that a morally good, morally trustworthy agent would stand for, and that the agent himself is morally trustworthy. (shrink)

This study examines the impact of culture on regulation and corruption. Our empirical results suggest that cultural values have significant effects on countries’ regulatory policies, levels of corruption, and economic development. Contrary to the conclusions drawn by others, this study shows no significant relationship between the regulatory policies of countries and their perceived levels of corruption. Thus, evidence of the “public choice view” toward entry regulation derived in related studies seems to be at least attenuated.

The real history of the covey of attention-artists who call themselves "The Birds." A great deal of uncertainty--and even some genuine confusion--surrounds the origin, evolution, and activities of the so-called Avis Tertia or "Order of the Third Bird." Sensational accounts of this "attentional cult" emphasize histrionic rituals, tragic trance-addictions, and the covert dissemination of obscurantist ontologies of the art object. Hieratic, ecstatic, and endlessly evasive, the Order attracts sensual misfits and cabalistic aesthetes--both to its ranks, and to its scholarship. In (...) recent years, however, the revisionist work of the research collective ESTAR(SER) has done much to clear the air, bringing archival precision to the history of this covey of attention-artists who call themselves "The Birds." Gathering the best articles of the last twenty years of The Proceedings of ESTAR(SER), this volume represents a landmark in the history of aesthetic practices, and will be a point of departure for future work wading the muddy marshes at the limits of historicism."--Publisher description.
