I argue for the viability of one neglected way of developing supervenience-based objections to metaethical non-naturalism. This way goes through a principle known as ‘Hume’s Dictum’, according to which there are no necessary connections between distinct existences. I challenge several objections to the Hume’s Dictum-based argument. In the course of doing so, I formulate and motivate modest and precise versions of Hume’s Dictum, illustrate how arguments employing these principles might proceed, and argue that the Hume’s Dictum argument enjoys some advantages (...) relative to other supervenience-based objections to non-naturalism.

I examine issues in the philosophy of religion at the intersection of what possibilities there are and what a God, as classically conceived in the theistic philosophical tradition, would be able to do. The discussion is centered around arguing for an incompatibility between theism and two principles about possibility and ability, and exploring what theists should say about these incompatibilities. -/- I argue that theism entails that certain kinds and amounts of evil are impossible. This puts theism in conflict with (...) popular principles of modal recombination. However, theists have plausible explanations for the violations of recombination that they posit, and can suitably amend these principles without giving up their usefulness in accounting for what possibilities there are. -/- I also argue that despite the impossibility of these evils, God is able to bring these evils about. This puts theism in conflict with the principle that no one is able to do the impossible. However, theists can give a plausible account of why God is unique in being able to do the impossible, and have distinctive resources to address the arguments in favor of the idea that no one is able to do the impossible. And by denying this principle, theists are able to resolve several otherwise difficult puzzles, including reconciling conflicts between the divine attributes. (shrink)

There is a very plausible principle linking abilities and possibilities: If S is able to Φ, then it is metaphysically possible that S Φ’s. Jack Spencer recently proposed a class of counterexamples to this principle involving the ability to know certain propositions. I renew an argument against these counterexamples based on the unknowability of Fitch propositions. In doing so, I provide a new argument for the unknowability of Fitch propositions and show that Spencer’s counterexamples are in tension with a principle (...) weaker than the one linking abilities and possibilities.

I examine two related arguments for the claim that if God is omnipotent, God cannot lack abilities such as the ability to do evil or to act irrationally. Both arguments concern the idea that omnipotence is inconsistent with being dominated with respect to abilities. I raise new issues in the formulation of such dominance principles about ability, and attempt to solve them. I also discuss and reject existing objections to these arguments. I conclude that these arguments are promising but not (...) conclusive, and that important work remains to be done in formulating the relevant dominance principles. (shrink)

In this empirical paper, Jay, Stone, Meksin, Merck, Gordon and Hirst examine whether jury deliberations, in which individuals collaboratively recall and discuss evidence of a trial, shape the jurors’ memories. In doing so, Jay and colleagues provide a highly ecologically valid baseline for future investigation into why, how and when selective recall either facilitates remembering or leads to forgetting during jury deliberations. In particular, Jay et al. explore the specific social and cognitive mechanisms that might lead to either memory facilitation (...) (RIFA – Retrieval Induced Facilitation) and forgetting (RIF ‐ Retrieval Induced Forgetting) during jury deliberation. (shrink)

In some recent work, John N.Williams defends a new objection to the defeasibility theory of knowledge. But the objection is of wider interest, since Williams also suggests that this style of objection may undermine other theories of knowledge. I distinguish two versions of Williams’ objection. I then show that the first version relies on false conceptual principles, and the second relies on a specific and dubious conception of the goal of the analysis of knowledge.

The goal of this study was to evaluate affective changes induced during mental imaging of instinctual action patterns. Subjects were first trained to simulate the bodily rhythms of laughter and crying and were then trained to image these processes without any movement. The mere imagination of the motor imagery of laughter and crying were sufficient to significantly facilitate happy and sad mood ratings as monitored by subjective self-report. In contrast, no changes in mood were reported while imaging the affectively neutral (...) task of walking. The work suggests that motor imagery is sufficient to modify emotional feelings, suggesting the feasibility of this method for brain imaging of emotional processes. (shrink)

Aims. Currently, methylphenidate (MPH, trade name Ritalin) is the most widely prescribed medication for attention deficit/hyperactivity disorder (ADHD). We examined the ability of repeated MPH administration to produce a sensitized appetitive eagerness type response in laboratory rats, as indexed by 50-kHz ultrasonic vocalizations (50-kHz USVs). We also examined the ability of MPH to reduce play behavior in rats which may be partially implicated in the clinical efficacy of MPH in ADHD. Design. 56 adolescent rats received injections of either 5.0 mg/kg (...) MPH, or vehicle each day for 8 consecutive days, and a week later received a challenge injection of either MPH or vehicle. Measurements. Both play behavior (pins) and 50-kHz USVs were recorded after each drug or vehicle administration. Results. MPH challenge produced a substantial 73% reduction in play behavior during the initial treatment phase, and during the last test (1 week post drug), 50-kHz USVs were elevated approximately threefold only in animals with previous MPH experience. Conclusions. These data suggest that MPH treatment may lead to psychostimulant sensitization in young animals, perhaps by increasing future drug-seeking tendencies due to an elevated eagerness for positive incentives. Further, we hypothesize that MPH may be reducing ADHD symptoms, in part, by blocking playful tendencies, whose neuro-maturational and psychological functions remain to be adequately characterized.

This article explores Hannah Arendt's insights into the forms of social control operating especially in democracies, together with the possibility of resistance to such control. Since the way in which one defines freedom informs one's understanding of the techniques that suppress, regulate, and modify behaviour, the article begins by sketching Arendt's notion of freedom, and compares this to its liberal counterpart. That discussion leads to Arendt's conception of power, whose corollary is freedom, and whose suppression amounts to control. The institutional (...) and ideological infrastructure that accompanies the encroachment of ?the social? ? which Arendt links to the hegemony of liberalism ? is conceived as rendering the individual both powerless and apathetic. The article concludes with suggestions regarding resistance to modern forms of control, viewing Arendt's ontology as a source of tenable strategies for the deepening of democracy. (shrink)

Mammalian brains contain a variety of self-centered socio-emotional systems. An understanding of how they interact with more recent cognitive structures may be essential for understanding empathy. Preston & de Waal have neglected this vast territory of proximal brain issues in their analysis.

Freedom, conceived ontologically, is power's condition of possibility. Yet, considering that the subject's interests and identity are constantly shaped, one still has to explain how – theoretically speaking – individuals can resist control. This is precisely the issue I address in the following pages. Following a brief overview of Foucault's contribution to our understanding of power, I turn to discuss the role of visibility vis-à-vis control, and show how the development of disciplinary techniques reversed the visibility of power. While Foucault (...) illustrates that during different historical periods, distinct modes of visibility are produced by power in order to control society, I argue that the very same power that produces visibility is concomitantly dependent upon it. In addition, I maintain that visibility is a necessary component of resistance. But Foucault – perhaps due to his premature death – never adequately explains how individuals can resist the mechanisms of control in a world in which power is ubiquitous. To help clarify this enigma, I turn to Hannah Arendt's insights into power, freedom, plurality, and natality. These concepts, I claim, can serve as a corrective to Foucault because they make room for resistance without assuming that humans can exit power's web. (shrink)
