Compiled by an archaeologist and philosopher of science, Science at the Frontiers: Perspectives on the History and Philosophy of Science supplements current literature in the history and philosophy of science with essays approaching the traditional problems of the field from new perspectives and highlighting disciplines usually overlooked by the canon. William H. Krieger brings together scientists from a number of disciplines to answer these questions and more in a volume appropriate for both students and academics in the field.

We use data collected among Hadza hunter-gatherers between 2005 and 2009 to examine hypotheses about the causes and consequences of men’s foraging and food sharing. We find that Hadza men foraged for a range of food types, including fruit, honey, small animals, and large game. Large game were shared not like common goods, but in ways that significantly advantaged producers’ households. Food sharing and consumption data show that men channeled the foods they produced to their wives, children, and their consanguineal (...) and affinal kin living in other households. On average, single men brought food to camp on 28% of days, married men without children at home on 31% of days, and married men with children at home on 42% of days. Married men brought fruit, the least widely shared resource, to camp significantly more often than single men. A model of the relationship between hunting success and household food consumption indicates that the best hunters provided 3–4 times the amount of food to their families than median or poor hunters. These new data fill important gaps in our knowledge of the subsistence economy of the Hadza and uphold predictions derived from the household and kin provisioning hypotheses. Key evidence and assumptions backing prior claims that Hadza hunting is largely a form of status competition were not replicated in our study. In light of this, family provisioning is a more viable explanation for why good hunters are preferred as husbands and have higher fertility than others. (shrink)

Frank Hindriks has attempted to derive a variant of Timothy Williamson’s knowledge rule for assertion on the basis of a more fundamental belief expression analysis of that speech act. I show that his attempted derivation involves a crucial equivocation between two senses of ‘must,’ and therefore fails. I suggest two possible repairs; but I argue that even if they are successful, we should prefer Williamson’s fully general knowledge rule to Hindriks’s restricted moral norm.

Time travel is a solved problem. Einstein showed that if you travel in a spaceship for months at speeds close to the speed of light, you can return to earth centuries in the future.

Carey has argued that there is a system of core numerical cognition – the analog magnitude system – in which cardinal numbers are explicitly represented in iconic format. While the existence of this system is beyond doubt, this paper aims to show that its representations cannot have the combination of features attributed to them by Carey. According to the argument from abstractness, the representation of the cardinal number of a collection of individuals as such requires the representation of individuals as (...) such, and this in turn requires non-iconic format, from which it is concluded that the explicit representation of the cardinal number of some individuals requires non-iconic representational format. In support of the first premise, an account is given of what approximate cardinal numbers might be, and in support of the second, a direct argument is articulated and defended. Finally, in response to an objection, a second argument for the central thesis is provided. While the discussion is couched in the terms of Carey’s work, the considerations it adduces are perfectly general, and the conclusion should therefore be taken into consideration by all those aiming to characterize the AM system.

Even if we do not observe those who own or manage capital doing anything, are there nevertheless good reasons for saying that they have power over government? My thesis is that, on any analysis of `power over others' that enables us to say that voters have power over those elected and that consumers have power over producers, we also have to say that those who own or control capital have power over government. Conversely, the reasons that can be given (and (...) have been given) for denying that owners of capital have power over governments would be equally good reasons for denying that voters have power over governments and that consumers have power over producers. Key Words: power • capitalism • democracy. (shrink)

It is well-known that classical models of belief are not realistic representations of human doxastic capacity; equally, models of actions involving beliefs, such as decisions based on beliefs, or changes of beliefs, suffer from a similar inaccuracies. In this paper, a general framework is presented which permits a more realistic modelling both of instantaneous states of belief, and of the operations involving them. This framework is motivated by some of the inadequacies of existing models, which it overcomes, whilst retaining technical (...) rigour in so far as it relies on known, natural logical and mathematical notions. The companion paper (Towards a “sophisticated” model of belief dynamics. Part II) contains an application of this framework to the particular case of belief revision. (shrink)

This paper argues that the church should give especial care to the needs of older folk in their communities, needs that are often neglected. It analyses why such folk have especial needs in our contemporary society and suggests practical ways that churches can and should respond. It summarises particular approaches to learning to grow old, and to die well, given by various authors who have had experience in these areas. It considers the problem of pain and suffering and suggests a (...) dualistic approach that can give comfort. (shrink)

The structure of Reichenbach's pragmatic vindication of induction is analysed in detail. The argument is seen to proceed in two stages, the first being a pragmatic justification of the frequency interpretation of probability which is taken as a license for considering the aim of induction to be the discovery of limiting relative frequencies, and the second being the pragmatic justification of induction itself. Both justifications are found to contain flaws, and the arguments used to support Reichenbach's definition of the aim (...) of induction presuppose the availability of a type of predicate which generates paradoxes closely related to Goodman's "grue-bleen" paradox. Next, Salmon's "Criterion of Linguistic Invariance" is evaluated as a canon of inductive logic, which singles out the "straight rule" from an infinite class of convergent inductive rules. Upon close examination, its credentials are seen to be unimpressive. In connection with Salmon's work on linguistic invariance, we take a closer look at the impact of the Goodman paradox on probability estimator rules like Reichenbach's "straight rule." We find that its undesirable consequences for such systems of inductive logic cannot be escaped by Salmon's solution, or indeed by any solution whose motivating idea is to rule "queer" predicates out of court. Finally, the discussion of the Goodman paradox leads us to a modest methodological proposal for systems of inductive logic which incorperate probability estimator rules of the type at issue.

The theory of human moral evolution elaborated in the later work of Jürgen Habermas represents one of the most challenging and provocative of recent, linguistically inspired attempts to reinterpret our understanding of Western history. In critically examining this theory, the present article identifies some major problems with Habermas's reinterpretation of the history of the formation of Western civilization as the universal pragmatic process of the evolution of human moral communicative competences. Drawing on the works of Norbert Elias and Michel Foucault, (...) the article seeks to show how the formal grounding of Habermas's evolutionary theory in the categories of his universal pragmatic conception of communicative action ultimately prevents him from grasping the radically embodied nature of human discursive practice and its implications for the historical process of the formation of human moral will.

Religions don’t simply make claims about the world; they also offer existential resources, resources for dealing with basic human problems, such as the need for meaning, love, identity, and personal growth. For instance, a Buddhist’s resources for addressing these existential needs are different than a Christian’s. Now, imagine someone who is agnostic but who is deciding whether to put faith in religion A or religion B. Suppose she thinks A and B are evidentially on par, but she regards A as (...) offering much more by way of existential resources. Is it epistemically rational for her to put her faith in A rather than B on this basis? It is natural to answer No. After all, what do the existential resources of a religion have to do with its truth? However, I argue that this attitude is mistaken. My thesis is that the extent to which it is good for a certain religion to be true is relevant to the epistemic rationality of faith in that religion. This is plausible, I’ll argue, on the correct account of the nature of faith, including the ways that emotion and desire can figure into faith and contribute to its epistemic rationality. (shrink)

The three main approaches to the metaphysics of intentionality can arguably be subjected to analysis in terms of grammatical point of view: the approach of the (internalist) phenomenal intentionality programme (plus productivism about linguistic content) may be regarded as first-personal; interpretationism, perhaps, as second-personal; and (reductive externalist) causal information theories (including teleosemantics) as third-personal. After making this plausible, the current paper focusses on the role of the interpreter (if any) in interpretationism. It argues that, despite some considerations from the publicity (...) of meaning potentially suggesting the contrary, radical interpretation is not subject to epistemic constraint; nor should the interpretationist appeal to the idiosyncratic interests of actual interpreters, thereby rendering the approach irremediably relativistic. Instead, an appeal to the pure form of interestedness is all that is involved; this supports a methodologically non-reductive outlook on intentionality. (shrink)

The tendency among working journalists to view ethics negatively, and ethical decision making as an attempt to inhibit their work by post facto sniping, is in part attributable to the way ethics is still taught in some undergraduate journalism programs - as a compendium of what journalists should not do. By adopting an approach that helps students and working journalists recognize ethics as affirmative, systematic, integrative, and definitive, ethics teachers can help foster a conception of ethics as positive, helpful, and (...) fundamental to the duty to inform.

The arguments for Bayesianism in the literature fall into three broad categories. There are Dutch Book arguments, both of the traditional pragmatic variety and the modern ‘depragmatised’ form. And there are arguments from the so-called ‘representation theorems’. The arguments have many similarities, for example they have a common conclusion, and they all derive epistemic constraints from considerations about coherent preferences, but they have enough differences to produce hostilities between their proponents. In a recent paper, Maher (1997) has argued that the (...) pragmatised Dutch Book arguments are unsound and the depragmatised Dutch Book arguments question begging. He urges we instead use the representation theorem argument as in his (1993). In this paper I argue that Maher’s own argument is question-begging, though in a more subtle and interesting way than his Dutch Book wielding opponents. (shrink)
