The Covid-19 pandemic has led to severe shortages of many essential goods and services, from hand sanitizers and N-95 masks to ICU beds and ventilators. Although rationing is not unprecedented, never before has the American public been faced with the prospect of having to ration medical goods and services on this scale.

We would like to thank the commentators for their generous comments, valuable insights and helpful suggestions. We begin this response by discussing the selfishness axiom and the importance of the preferences, beliefs, and constraints framework as a way of modeling some of the proximate influences on human behavior. Next, we broaden the discussion to ultimate-level (that is evolutionary) explanations, where we review and clarify gene-culture coevolutionary theory, and then tackle the possibility that evolutionary approaches that exclude culture might be sufficient (...) to explain the data. Finally, we consider various methodological and epistemological concerns expressed by our commentators. (shrink)

Researchers from across the social sciences have found consistent deviations from the predictions of the canonical model of self-interest in hundreds of experiments from around the world. This research, however, cannot determine whether the uniformity results from universal patterns of human behavior or from the limited cultural variation available among the university students used in virtually all prior experimental work. To address this, we undertook a cross-cultural study of behavior in ultimatum, public goods, and dictator games in a range of (...) small-scale societies exhibiting a wide variety of economic and cultural conditions. We found, first, that the canonical model – based on self-interest – fails in all of the societies studied. Second, our data reveal substantially more behavioral variability across social groups than has been found in previous research. Third, group-level differences in economic organization and the structure of social interactions explain a substantial portion of the behavioral variation across societies: the higher the degree of market integration and the higher the payoffs to cooperation in everyday life, the greater the level of prosociality expressed in experimental games. Fourth, the available individual-level economic and demographic variables do not consistently explain game behavior, either within or across groups. Fifth, in many cases experimental play appears to reflect the common interactional patterns of everyday life. Key Words: altruism; cooperation; cross-cultural research; experimental economics; game theory; ultimatum game; public goods game; self-interest. (shrink)

Zuidema et al. illustrate how empirical AGL studies can benefit from computational models and techniques. Computational models can help clarifying theories, and thus in delineating research questions, but also in facilitating experimental design, stimulus generation, and data analysis. The authors show, with a series of examples, how computational modeling can be integrated with empirical AGL approaches, and how model selection techniques can indicate the most likely model to explain experimental outcomes.

In this paper we show that being blameworthy for not blaming and being blameworthy for victim blaming are structurally similar. Each involve the two traditional contours of moral responsibility: a knowledge condition and a control condition. But interestingly, in these cases knowledge and control are importantly interrelated. Being in a relationship with another person affords us varying degrees of knowledge about them. This knowledge in turn affords agents in relationships varying degrees of influence over one another. Cases where an agent (...) is especially blameworthy for failing to blame a friend, a close colleague, or a spouse highlight this. The interdependence of these two conditions in interpersonal relationships sheds (partial) light on why victim blaming is morally wrong. We argue that victim blamers suffer from a kind of moral myopia by only focusing on what the victim could do, in virtue of their being in a relationship of some sort with their abuser, to avoid abuse. We focus specifically on cases where such moral myopia is fueled by misogynistic and hierarchical gender schema and scripts. (shrink)

The current ethical norms of genomic biobanking creating and maintaining large repositories of human DNA and/or associated data for biomedical research have generated criticism from every angle, at both the practical and theoretical levels. The traditional research model has involved investigators seeking biospecimens for specific purposes that they can describe and disclose to prospective subjects, from whom they can then seek informed consent. In the case of many biobanks, however, the institution that collects and maintains the biospecimens may not itself (...) be directly involved in research, instead banking the biospecimens and associated data for other researchers. Moreover, the future uses of biospecimens may be unknown, if not unknowable, at the time of collection. Biobanking may thus stretch the meanings of inform and consent to their breaking point: if you cannot inform subjects about what their biospecimens will be used for, what can they consent to? Given that informed consent by individual subjects is the ethical gold standard, the seeming dilution of the concept in the context of biobanking is a profound problem. (shrink)

This qualitative study indentifies how corporate responsibility (CR) practices are diffused to companies, as well as the factors that influence this diffusion process. Forest companies, industry associations, non-governmental organizations, and academics in Brazil, Canada, and the United States participated in this interview-based study. Data emerging from a grounded theory approach revealed three factors influencing the diffusion of CR practices to companies: (1) external contextual characteristics, (2) connectors, and (3) experts and expert organizations. These three factors influence each other, meaning that (...) the diffusion process of CR practices is somewhat cyclic. These interactions are usually manifested by companies and expert organizations influencing each other’s actions, being influenced by the external environment, and contributing to the CR trends that are observed in the external environment.

The aim of this paper is to show the relationship between John XXIII and Robert K. Greenleaf’s understanding of leadership. By taking into consideration Greenleaf’s theory of servant-leadership – from conceptualization to model development – and Larry Spears’ influential rubric of ten servant-leadership characteristics, we will show how servant-leadership theory goes in line with that of John XXIII when both are based on a notion of the common good and human dignity.

Cicero's letter to his brother Quintus from February 54 is best known for containing the sole explicit contemporary reference to Lucretius’De rerum natura, but it is also notable as the source of the only extant reference of any kind to another (presumably) philosophical didactic poem, Sallustius’Empedoclea(Q. fr.2.10(9).3= SB 14):Lucretii poemata, ut scribis, ita sunt: multis luminibus ingenii, multae tamen artis. sed, cum ueneris. uirum te putabo, si Sallusti Empedoclea legeris; hominem non putabo.Lucretius’ poems are just as you write: they show (...) many flashes of inspiration, but many of skill too.

In this essay I propose to facilitate a dialogue between the thoughts of conceptual artist and philosopher, Daya Krishna, and the work of literary artist, Vikas Swarup. The central concept that will be “interrogated” in this dialogue is that of knowledge. I will apply my understanding of Daya Krishna’s conceptualization of the knowledge enterprise on to Vikas Swarup’s attitude toward knowledge as embodied in his 2005 novel, Q & A. This exercise serves to create a context in which conceptions of (...) knowledge from diverse fields (hardcore philosophy and popular culture) can be in dialogue with one another, and thereby enhance meaning. Daya Krishna observes that the loss of certainty and proof in our postmodern age erodes the concept of knowledge. He alternately suggests new indicators with which to define knowledge, indicators which factor in chance and probability, and take into account inherent moral qualities of knowledge. I argue that this alternative model of knowledge finds an expression in Swarup’s novel. (shrink)

Why eschew luxury? The traditional arguments for frugality typically focus on what is good for the individual. Some see frugality as morally valuable because it tends to be associated with other virtues such as wisdom, honesty, or sincerity. Some find the natural, uncluttered, focused character of a simple lifestyle aesthetically appealing. The most common argument, though, is that simple living is the surest route – some even say the only route – to happiness.

By deduction, we often extend both our knowledge and our justified belief. Moreover, in achieving knowledge or justified belief of some proposition, we commonly acquire justification for believing many of its entailed consequences, such as at least some of those that self-evidently follow from it. These and related facts have led some philosophers to endorse strong closure principles, for instance: If a person, S, is justified in believing a proposition, p, and p entails q, then S is justified in believing (...) q. Others have denied such principles, whether for justification or, with the appropriate additions, for knowledge. The debate continues. There is, however, this much consensus: there are difficult problems about the scope of closure, and epistemology should develop theories that can resolve them. (shrink)

Both a priori physicalism and a posteriori physicalism combine a metaphysical and an epistemological thesis. They agree about the metaphysical thesis: our world is wholly physical. Most agree that this requires everything that there is must be necessitated by the sort of truths described by physics. If we call the conjunction of the basic truths of physics P, all physicalists agree that P entails for any truth Q. Where they disagree is whether or not this entailment can be known a (...) priori. The a priori physicalist says it can, the a posteriori physicalist says it cannot. Though a posteriori physicalism is probably the dominant view, it is really a surprising and somewhat unlikely stance. In this article, the nature of the view is discussed, and two arguments are presented that should cause us to look again at the potential of a priori physicalism. (shrink)

Formalising deontic concepts, such as obligation, prohibition and permission, is normally carried out in a modal logic with a possible world semantics, in which some worlds are better than others. The main focus in these logics is on inferring logical consequences, for example inferring that the obligation O q is a logical consequence of the obligations O p and O. In this paper we propose a non-modal approach in which obligations are preferred ways of satisfying goals expressed in first-order logic. (...) To say that p is obligatory, but may be violated, resulting in a less than ideal situation s, means that the task is to satisfy the goal p ∨ s, and that models in which p is true are preferred to models in which s is true. Whereas, in modal logic, the preference relation between possible worlds is part of the semantics of the logic, in this non-modal approach, the preference relation between first-order models is external to the logic. Although our main focus is on satisfying goals, we also formulate a notion of logical consequence, which is comparable to the notion of logical consequence in modal deontic logic. In this formalisation, an obligation O p is a logical consequence of goals G, when p is true in all best models of G. We show how this non-modal approach to the treatment of deontic concepts deals with problems of contrary-to-duty obligations and normative conflicts, and argue that the approach is useful for many other applications, including abductive explanations, defeasible reasoning, combinatorial optimisation, and reactive systems of the production system variety.

Objective: To determine the usefulness of Q methodology to locate and describe shared subjective influences on clinical decision making among participant physicians using hypothetical cases containing common ethical issues. Design: Qualitative study using by-person factor analysis of subjective Q sort data matrix. Setting: University medical center. Participants: Convenience sample of internal medicine attending physicians and house staff (n = 35) at one midwestern academic health sciences center. Interventions: Presented with four hypothetical cases involving urgent decision making near the end of (...) life, participants selected one of three specific clinical actions offered for each case. Immediately afterward and while considering their decision, each respondent sorted twenty-five subjective self-referent items in terms of the influence of each statement on their decision-making process. By-person factor analysis, where participants are defined as variates, yielded information about the attitudinal background the physicians brought to their consideration of each hypothetical case. We performed a second-order factor analysis on all of the subjective viewpoints to determine if a smaller core of shared attitudes existed across some or all of the four case vignettes. Factor scores for each item and post-sort comments from interviews conducted individually with each respondent guided the interpretation of ethical perspective used by these respondents in making clinical decisions about the cases. Measurements and Main Results: Second-order factor analysis on seventeen viewpoints used by physicians in the four hypothetical urgent decision cases revealed three moderately correlated (r 2 < 40%) subjective core attitudinal guides used broadly among all the cases and among sixteen of the seventeen original factors. Across all the cases, our participants were guided in general by: (1) patient-focused beneficence, (2) a patient- and surrogate-focused perspective that includes risk avoidance, and (3) best interest of the patient guided by ethical values. Economic impact on the physician, expediency in resolution of the situation, and the expense of medical treatment were not found to be influential determinants in this study. Conclusions: Q sorting and by-person factor analysis are useful qualitative methodological tools to study the complex structure of subjective attitudes that influence physicians in making medical decisions. This study revealed the subjective viewpoints used by our physician participants as they made ethically challenging treatment decisions. The three second-order factors identified here are grounded in current bioethical values as well as the personal traits of physicians. The participants' decision methods appear to resemble casuistry more than principle-based decision making. Generalizability of results will require further studies. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:THE MODALITY OF BEING ROBERT c. BEISSEL Phoenix, Arizona " It must be of itself that the divine thought thinks." Aristotle, Metaphysics, Bk. 12, c. 9. ST. THOMAS IS AS Neoplatonic as Plotinus in his awareness that Being is not being and that being is not Being.1 Yet, like St. Augustine, St. Thomas knew that being is closer to Being than to itself; he knew that beyond the (...) question " Why being rather than nothing? " lay another, a more baffling one, namely, " Why being rather than only Being? " That being is not Being is indisputable. The philosopher seeks to understand how, in spite of that, being is and why. How to understand being while really distinguishing it from Being without diminishing Being-such is the puzzle. The difficulty lies in finding its answer without denying or changing the terms of the question, no matter how hard those terms may be. A problem is sometimes underestimated, even by one who knows its answer, because its answer is not really understood. A school child may not think the question "Why is the earth round? " difficult, when by rote it knows that gravity causes all earthly bodies to fall to a center. Only when the child perceives that gravity may not be easy to understand does it appreciate the difficulty of the question. St. Thomas cannot be accused of underestimating the problem 1 Two notes : one on terminology and one on citations. First, " Being " here signifies ens primum, the god, the creator; "being " signifies being composed of potentiality and act, including both material and immaterial substance and accidents, ens creatum. Second, citations are given below only for points of Aristotelian-Thomistic sources which the specialist reader may want to verify or into which that reader may wish to inquire further. For the rest, it has been presumed the reader is familiar enough with the Aristotelian-Thomistic philosophical tradition to recognize the common doctrine of the school. 49 50 ROBERT C. BEISSEL of being. He knew that, when Being is shown to be the cause of being, a puzzling implication follows, namely, that Being is the immediate analogical cause of being. The following pages detail the problem this implication presents and the solution it finds in the work of St. Thomas. I The philosophical ancient history of demiurges and intermediate intelligences supplied to keep Being decently removed from being attests to the difficulty of understanding what it means to say that Being is the immediate cause of being. Moderns deny the existence of Being for much the same reason that ancient philosophers placed intermediaries between Being and being: the ancients thought being unworthy of Being; the moderns think being so evidently imperfect that nothing like Being could be responsible for it. Although it lacks similarly clear historical witness, the difficulty of understanding what it means to say that Being is an analogical cause of being is no less striking. Univocal causes are of the same species as their effects and, therefore, are distinct from them numerically by reason of subject or matter. But, while analogical causes are specifically different from the subjects in which their effects are wrought, the perfections they cause in them are not distinct from the perfections of those causes. Indeed, those perfections in cause and effect are identical, not just in species but in number.2 Examples may be helpful here. Agents of natural generation are univocal causes of their issue, not only in factum esse, 2 Summa Theol. 1-2, q. 20, a. 3, ad 3. St. Thomas refers to this distinction in many places, e.g., 1, q. 4, aa. 2, 3c and ad 3; q. 13, a. Sc and ad 1; q. 104, a.1; Contra Gentes, 2, c. 21; 3, c. 65; 4, c. 7; De Ver., q. 10, a. 12, ad 3; and many other places in the works cited as well as in other works. (The interested reader is best advised to look at the Tabula Aurea for the distinction under the entry Causa.) It goes without saying that all talk of "cause" here presumes an Aristotelian notion of causality, not a Humean one. All causes actually causing exist simultaneously with their effects for as...

It is commonly supposed that evolutionary explanations of cognitive phenomena involve the assumption that the capacities to be explained are both innate and modular. This is understandable: independent selection of a trait requires that it be both heritable and largely decoupled from other `nearby' traits. Cognitive capacities realized as innate modules would certainly satisfy these contraints. A viable evolutionary cognitive psychology, however, requires neither extreme nativism nor modularity, though it is consistent with both. In this paper, we seek to show (...) that rather weak assumptions about innateness and modularity are consistent with evolutionary explanations of cognitive capacities. Evolutionary pressures can affect the degree to which the development of a capacity is canalized by biasing acquisition/ learning in ways that favor development of concepts and capacities that proved adaptive to an organism's ancestors. q 1999 Elsevier Science B.V.

The treatment of identical particles in quantum mechanics rests on two (related) principles: the spin-statistics connection and the Symmetrization Postulate. In light of recent theories (such as q-deformed commutators) that allow for ‘small’ violations of the spin-statistics connection and the Symmetrization Postulate, we revisit the issue of how quantum mechanics deals with identical particles and how it supports or fails to support various philosophical stances concerning individuality. As a consequence of the expanded possibilities for quantum statistics, we argue that permutation (...) symmetry is best formulated as a formal property of the state function describing the system of particles rather than as a property of the individual particles. 1 Introduction 2 Philosophical background 2.1 Important terminology 2.1.1 Identity 2.1.2 Indistinguishability 2.1.3 Indiscernibility 2.2 When are particles indistinguishable? 2.3 The Principle of the Identity of Indiscernibles and quantum mechanics 2.4 The Principle of the Identity of Indiscernibles and logic 2.5 Particle history 2.6 Transcendental individuality 3 Some quantum formalism 3.1 The Principle of Permutation Invariance and the Symmetrization Postulate 3.2 The configuration-space approach 3.3 Commutators and anticommutators, and identical particle statistics 3.4 Q-mutators 4 Identical particle statistics: a holistic point of view 5 Conclusions.

University of Colorado, Boulder If there are laws of psychology, they would seem to hold only ceteris paribus (c.p., hereafter), i.e., other things being equal. If a person wants that q and believes that doing a is the most efficient way to make it the case that q, then she will attempt to do a—but not, however, if she believes that a carries with it consequences much more hated than q is liked, or she believes she is incapable of doing (...) a, or she gets distracted from her goal that q, or she suddenly has a severe brain hemorrhage, or.... No one can say precisely where the list ends, but the idea is supposed to be clear enough: normally the law holds, but there are many cases, exceptions, one might say, in which the law does not; the difficulty of characterizing these exceptions invites the qualification ‘c.p.’ as a catch-all.

In The Market Experience, Robert Lane restates the central criticism of economic views of human satisfaction?namely, that they define welfare as utility and, in practice if not in theory, use money as the measure of utility, while in reality utility (or welfare) ought to be defined as happiness.

Since increases in income above a certain minimum do not increase happiness, work must be made more meaningful. (shrink)

Thābit b. Qurra, a Sabian of Ḥarrān, and his descendants remained in their ancestral religion for six generations. Why did they persist despite pressure to convert? This article argues that religious self-identification as a Sabian could be a distinct advantage in Baghdad’s elite circles. It focuses on Thābit’s great-grandson Abū Isḥāq Ibrāhīm b. Hilāl al-Ṣābī and his poetry as collected by al-Thaʿālibī. Two members of the family who did convert are also considered by way of contrast.

Quons are particles characterized by the parameter q, which permits smooth interpolation between Bose and Fermi statistics; q = 1 gives bosons, q = -1 gives fermions. In this paper we give a heuristic argument for an extension of conservation of statistics to quons with trilinear couplings of the form ffb, where f is fermion-like and b is boson-like. We show that q f 2 = qb. In particular, we relate the bound on qγ for photons to the bound on (...) qe for electrons, allowing the very precise bound for electrons to be carried over to photons. An extension of this argument suggests that all particles are fermions or bosons to a high precision. (shrink)

-/- In the Summa Theologiae ‘simplicity’ is treated as pre–eminent among the terms which may properly be used to describe the divine nature. The Question in which Thomas demonstrates that God must be ‘totally and in every way simple’ (1.3.7) immediately follows the five proofs of God's existence, preceding the treatment of His other perfections, and being frequently used as the basis for proving them. Then in Question 13 ‘univocal predication' is held to be ‘impossible between God and creatures’ so (...) that at best ‘some things are said of God and creatures analogically’ because of the necessity of using ‘various and multiplied conceptions’ derived from our knowledge of created beings to refer to what in God is simple for ‘the perfections flowing from God to creatures… pre–exist in God unitedly and simply, whereas in creatures they are received divided and multiplied’ (1.13.5). In line with this, in the De Potentia Dei the treatment of analogical predication is integrated into that of ‘the Simplicity of the Divine Essence’ (Q 7). Moreover, it lies at the root of Thomas's rejection of any possibility of a Trinitarian natural theology such as, for instance, St Anselm or Richard of St Victor had attempted to develop, on the grounds that ‘it is impossible to attain to the knowledge of the Trinity by natural reason’ since ‘we can know what belongs to the unity of the essence, but not what belongs to the distinction of the persons’ (1.32.1). Even modern minds sympathetic to Thomas have clearly found it difficult to understand his concern for the divine simplicity: in his Aquinas Lecture Plantinga speaks for many in stating that it is ‘a mysterious doctrine’ which is ‘exceedingly hard to grasp or construe’ and ‘it is difficult to see why anyone should be inclined to accept it’. Not surprisingly, therefore, some of the most widely read twentieth–century commentators on Aquinas have paid little attention to it. Increased interest has recently been shown in it, but a number of discussions pay insufficient attention to the historical context out of which Thomas's interest in the doctrine emerged, and consequently tend to misconstrue its nature.

After almost a decade, the discussion initiated by Professor Edmund Gettier's provocative paper “Is Justified True Belief Knowledge?” continues. The most recent contribution to this discussion is Professor John Turk Saunders' attempt to counter Professor Irving Thalberg's claim that a principle that Gettier employs in reaching his notorious negative conclusion is unjustified. I am moved to add to the discussion at this time because it seems to me that the principle in question is unjustified. But more fundamentally, Gettier's argument fails (...) because the putative counter-examples on which it rests fail to make their intended point. I shall discuss these claims in turn.The epistemic principle which I consider unjustified is the one which Thalberg has called the Principle of Deducibility for Justification and which Gettier formulates as follows: “for any proposition P, if S is justified in believing P, and P entails Q, and S deduces Q from P and accepts Q as a result of this deduction, then S is justified in believing Q.”.

A set X of nonnegative integers is computably enumerable (c.e.), also called recursively enumerable (r.e.), if there is a computable method to list its elements. Let ε denote the structure of the computably enumerable sets under inclusion, $\varepsilon = (\{W_e\}_{e\in \omega}, \subseteq)$ . We previously exhibited a first order ε-definable property Q(X) such that Q(X) guarantees that X is not Turing complete (i.e., does not code complete information about c.e. sets). Here we show first that Q(X) implies that X has (...) a certain "slowness" property whereby the elements must enter X slowly (under a certain precise complexity measure of speed of computation) even though X may have high information content. Second we prove that every X with this slowness property is computable in some member of any nontrivial orbit, namely for any noncomputable A ∈ ε there exists B in the orbit of A such that X ≤ T B under relative Turing computability (≤ T ). We produce B using the Δ 0 3 -automorphism method we introduced earlier. (shrink)

The authors take as undefined the expression, "p is epistemically preferable to q for s at t", Which they interpret as referring to a relation that may hold among a man's believings ("he believes h"), His disbelievings ("he believes not-H"), And his withholdings ("he believes neither h nor not-H"). Seven axioms of epistemic preferability are set forth from which the authors deduce some 60 theorems. Some of these theorems are described as "pyrrhonistic." several fundamental epistemic concepts are defined in terms (...) of epistemic preferability. Among them are those suggested by the terms "some presumption in its favor", "acceptable", "beyond reasonable doubt", "evident", "certain", And "counterbalanced". (shrink)

Growing inequality and its implications for democratic polity suggest that corporate social responsibility has not proved itself in twenty-first century business, largely as it lacks clear criteria of demarcation for businesses to follow. Today the problem is viewed by many commentators as an ethical challenge to business itself. In response to this challenge, we begin by examining Porter and Kramer’s :64–77, 2011) call for a shift from a social responsibility to a shared value framework and the need to respond to (...) the problem of the ‘separation thesis’ between business and ethics :89–118, 1996; Harris and Freeman, Bus Ethics Q 18:541–548, 2008). We identify the eighteenth century economist and philosopher Adam Smith in his book The Theory of Moral Sentiments as a source for an ethical approach to business. Building on his central concept of ‘sympathy’, we introduce the idea of the Impartial Spectator Test, which we argue builds on traditional stakeholder perspectives and which provides an objective route to ethical criteria of demarcation. We conclude by assessing how this approach adds to the existing debate around social responsibility and shared value. (shrink)

A much discussed topic in the theory of choice is how a preference order among options can be derived from the assumption that the notion of ' choice' is primitive. Assuming a choice function that selects elements from each finite set of options, Arrow (Económica 26: 121-127,1959) already showed how we can generate a weak ordering by putting constraints on the behavior of such a function such that it reflects utility maximization. Arrow proposed that rational agents can be modeled by (...) such choice functions. Arrow's standard model of rationality has been criticized in economics and gave rise to approaches of bounded rationality. Two standard assumptions of rationality will be given up in this paper. First, the idea that agents are utility optimizers (Simon). Second, the idea that the relation of ' indifference' gives rise to an equivalence relation. To account for the latter, Luce (Econometrica 24: 178-191, 1956) introduced semi-orders. Extending some ideas of Van Benthem (Pac Philos Q 63: 193-203, 1982), we will show how to derive semi-orders (and so-called interval orders) based on the idea that agents are utility satisficers rather than utility optimizers.

Chalmers (The Conscious Mind, Oxford Unversity Press, Oxford 1996) has argued for a form of property dualism on the basis of the concept of a zombie (which is physically identical to normals), and the concept of the inverted spectrum. He asserts that these concepts show that the facts about consciousness, such as experience or qualia, are really further facts about our world, over and above the physical facts. He claims that they are the hard part of the mind-body issue. He (...) also claims that consciousness is a fundamental feature of the world like mass, charge, etc.He says that consciousness does not logically supervene on the physical and all current attempts to assert an identity between consciousness and the physical are just as non-reductive as his dualism. They are simply correlations and are part of the problem of the explanatory gap. In this paper, three examples of strong identities between a sensation or a quale and a physiological process are presented, which overcome these problems. They explain the identity in an a priori manner and they show that consciousness or sensations (Q) logically supervene on the physical (P), in that it is logically impossible to have P and not to have Q. In each case, the sensation was predicted and entailed by the physical. The inverted spectrum problem for consciousness is overcome and explained by a striking asymmetry in colour space. It is concluded that as some physical properties realize some sensations or qualia that human zombies are not metaphysically possible and the explanatory gap is bridged in these cases. Thus, the hard problem is overcome in these instances. (shrink)

Post in 1944 began studying properties of a computably enumerable set A such as simple, h-simple, and hh-simple, with the intent of finding a property guaranteeing incompleteness of A . From the observations of Post and Myhill , attention focused by the 1950s on properties definable in the inclusion ordering of c.e. subsets of ω, namely E = . In the 1950s and 1960s Tennenbaum, Martin, Yates, Sacks, Lachlan, Shoenfield and others produced a number of elegant results relating ∄-definable properties (...) of A , like maximal, hh-simple, atomless, to the information content of A . Harrington and Soare gave an answer to Post's program for definable properties by producing an ∄-definable property Q which guarantees that A is incomplete and noncomputable, but developed a new Δ 3 0 -automorphism method to prove certain other properties are not ∄-definable. In this paper we introduce new ∄-definable properties relating the ∄-structure of A to deg, which answer some open questions. In contrast to Q we exhibit here an ∄-definable property T which allows such a rapid flow of elements into A that A must be complete even though A may possess many other properties such as being promptly simple. We also present a related property NL which has a slower flow but fast enough to guarantee that A is not low, even though A may possess virtually all other related lowness properties and A may simultaneously be promptly simple.

We report the results of an experiment in which human subjects were trained to perform a perceptual matching task. Subjects were asked to manipulate comparison objects until they matched target objects using the fewest manipulations possible. An unusual feature of the experimental task is that efficient performance requires an understanding of the hidden or latent causal structure governing the relationships between actions and perceptual outcomes. We use two benchmarks to evaluate the quality of subjects’ learning. One benchmark is based on (...) optimal performance as calculated by a dynamic programming procedure. The other is based on an adaptive computational agent that uses a reinforcement-learning method known as Q-learning to learn to perform the task. Our analyses suggest that subjects were successful learners. In particular, they learned to perform the perceptual matching task in a near-optimal manner (i.e., using a small number of manipulations) at the end of training. Subjects were able to achieve near-optimal performance because they learned, at least partially, the causal structure underlying the task. In addition, subjects’ performances were broadly consistent with those of model-based reinforcement-learning agents that built and used internal models of how their actions influenced the external environment. We hypothesize that people will achieve near-optimal performances on tasks requiring sequences of action—especially sensorimotor tasks with underlying latent causal structures—when they can detect the effects of their actions on the environment, and when they can represent and reason about these effects using an internal mental model.

Stephen Hetherington has defended the tripartite analysis of knowledge (Hetherington in Philos Q 48:453–469, 1998; J Philos 96:565–587, 1999; J Philos Res 26:307–324, 2001a; Good knowledge, bad knowledge, Oxford University Press, Oxford, 2001b). His defence has recently come under attack (Madison in Australas J Philos 89(1):47–58, 2011; Turri in Synthese 183(3):247–259, 2012). I critically evaluate those attacks as well as Hetherington’s newest formulation of his defence (Hetherington in Philosophia 40(3):539–547, 2012b; How to know: A practicalist conception of knowledge, Wiley, Oxford, (...) 2011a; Ratio 24:176–191, 2011b; Synthese 188:217–230, 2012a). I argue that his newest formulation is vulnerable to a modified version of Madison’s and Turri’s objection. However, I argue that Hetherington’s considerations lend support to a different, though also radical, thesis which can meet the objection. This thesis is what I call the Divorce thesis: the theory of epistemic justification is importantly independent of the theory of knowledge. (shrink)

The most striking example of Roman intervention in the affairs of mainland Greece between the Achaean and Mithridatic Wars is provided by an inscription now in the Fitzwilliam Museum, Cambridge. This stone bears the text of a letter to the city of Dyme in Achaea from a Roman proconsul named Q. Fabius Maximus, which describes his trial and sentencing of certain men of Dyme whom he had judged responsible for a recent disturbance in that city. One crux to be resolved (...) is chronological: A date of c. 115 b.c. has long been generally accepted, but recently evidence from another, still unpublished inscription has been thought to point to the year 144. Further, the letter of Fabius Maximus has long been held to exemplify the close supervision that most scholars, regardless of their position on the vexed question of Greece's formal status after 146, assume was exercised over Greece by Roman commanders in Macedonia from the time of the Achaean War. The document has also often been cited to bolster the claim that Rome pursued in second-century Greece a conscious policy of suppressing democracy or the political aspirations of the lower class. This is not, of course, the place for reassessment of these old, complex controversies. My purpose here is rather to show that interpretation of the letter of Fabius Maximus has not always been sufficiently mindful of the many obscurities of the text and, consequently, of the events that lie behind it; too often the great lacunae in our knowledge have been filled with assumptions that beg the questions that are under debate.

In theories of gravity with a positive cosmological constant, we consider product solutions with flux, of the form (A)dS p ×S q . Most solutions are shown to be perturbatively unstable, including all uncharged dS p ×S q spacetimes. For dimensions greater than four, the stable class includes universes whose entropy exceeds that of de Sitter space, in violation of the conjectured “N-bound.” Hence, if quantum gravity theories with finite-dimensional Hilbert space exist, the specification of a positive cosmological constant will (...) not suffice to characterize the class of spacetimes they describe.
