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)

One central claim of orthodox Christianity is that in Jesus of Nazareth, God became man. On Chalcedonian orthodoxy, this involves one person, God the Son, having two natures, divine and human. If He does, one person has two properties, deity and humanity. But the Incarnation also involves concrete objects, God the Son (GS), Jesus’s human body (B) and—I will assume—Jesus’s human soul (S). If God becomes human, GS, B and S somehow become one thing. It would be good to have (...) a metaphysical account of their oneness. I have suggested one. Thomas Senor has criticized my suggestion. I now reply to his case. (shrink)

"Anselm of Canterbury gave the first modal "ontological" argument for God's existence. Yet, despite its distinct originality, philosophers have mostly avoided the question of what modal concepts the argument uses, and whether Anselm's metaphysics entitles him to use them. Here, Brian Leftow sets out Anselm's modal metaphysics. He argues that Anselm has an "absolute", "broadly logical", or "metaphysical" modal concept, and that his metaphysics provides acceptable truth makers for claims in this modality. He shows that his modal argument is (...) committed to the Brouwer system of modal logic, and defends the claim that Brouwer is part of the logic of "absolute" or "metaphysical" modality. He also defends Anselm's premise that God would exist with absolute necessity against all extant objections, providing new arguments in support of it and ultimately defending all but one premise of Anselm's best argument for God's existence"--.

While a necessary condition for perceiving a physical object is that the object cause the perceiver to undergo a sense experience, this condition is not sufficient. causal theorists attempt to provide a sufficient condition by placing constraints on the way the object causes the perceiver's experience. i argue that this is not possible since the relationship between a perceiver's experience and an object in virtue of which the perceiver perceives the object does not supervene on any of the ways in (...) which the object causes the perceiver's experience.

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.

Assume, for fun, that temporal parts theory is true, and that some kind of modal realism (perhaps based on ersatz worlds) is true. Within this grand metaphysical picture, what are the ordinary objects? Do they have many temporal parts, or just one? Do they have many modal parts, or just one? I survey the issues involved in answering this question, including the problem of temporary intrinsics, the problem of the many, Kripke's objections to counterpart theory and quantifier domain restrictions.

Jonathan Swift is best known as a satirist, a poet, and a polemicist, but he was also a historian and his historical vision played a prominent role in his thinking and in his writings. (Marshall 2015) This chapter explains how the experience of ‘loss’ affected Swift’s historical vision. Swift was a loser in many respects. Born Irish, Swift aspired to achieve professional success as a clergyman in the Church of England and as a politician in the service of the Tory (...) party. For the last four years of Queen Anne’s reign, Swift enjoyed privileged access to the machinations of Robert Harley’s ‘great’ ministry. Swift’s service to the crown was not rewarded with preferment but rather with exile back to Ireland. In his later life, Swift would reinvent himself as an Irish patriot and he would continue to work on revising his History of the Four Last Years of the Queen (written 1712-13; published 1758).

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.

Two naturalistic explications of propositional attitudes and their contents are distinguished: the language of thought based theory, on which beliefs are relations to sentences in the language of thought; and the propositional attitude based theory, on which beliefs are functional states of a functional system that does not imply a language of thought, although consistent with it. The latter theory depends on interpersonally ascribable conceptual roles; if these are not available, the language of thought theory has the advantage. But the (...) propositional attitude based theory explains intentionality and conceptual structure as well as the language of thought based theory, and it has two further advantages. First, it does not make the existence of beliefs and desires depend on the language of thought hypothesis. Secondly, its employment of interpersonally ascribable conceptual roles permits a theory of truth conditions to meet certain desiderata, such as a social basis for truth conditions, and a realist conception of truth.

Approaches to Wittgenstein brings together for the first time the many varied aspects of Wittgenstein's life, philosophy and aesthetic attitudes. It draws from many of his unpublished manuscripts to illuminate his work.

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)

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)

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.

This paper discusses the explanatory significance of the equilibrium concept in the context of an example of extremely complicated dynamical behavior. In particular, numerical evidence is presented for the existence of chaotic dynamics on a "strange attractor" in the evolutionary game dynamics introduced by Taylor and Jonker [also known as the "replicator dynamics"]. This phenomenon is present already in four strategy evolutionary games where the dynamics takes place in a simplex in three dimensional space-the lowest number of dimensions in which (...) such a strange attractor is possible. From a dynamical point of view, it is the attractor-rather than the equilibrium-that is of prime interest. (shrink)

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 functional approach to language holds that the forms of natural languages are created, governed, constrained, acquired, and used in the service of communicative functions. To evaluate this claim, we need to examine both the strengths and the weaknesses of the functional approach.
