Revonsuo proposed an intriguing and detailed evolutionary theory of dreams which stipulates that the biological function of dreaming is to simulate threatening events and to rehearse threat avoidance behaviors. The goal of the present study was to test this theory using a sample of 212 recurrent dreams that was scored using a slightly expanded version of the DreamThreat rating scale. Six of the eight hypotheses tested were supported. Among the positive findings, 66% of the recurrent dream reports contained one or (...) more threats, the threats tended to be dangerous and aimed at the dreamer, and when facing a threat, the dreamer tended to take defensive or evasive actions that were possible and reasonable. However, less than 15% of the recurrent dreams depicted realistic and probable situations critical for one’s physical survival or reproductive success and the dreamer rarely succeeded in fleeing the threat despite important and appropriate efforts. The findings thus provide mixed support for the threat simulation theory. (shrink)

ObjectiveFreezing of gait is detrimental to patients with idiopathic Parkinson’s disease. Its pathophysiology represents a multilevel failure of motor processing in the cortical, subcortical, and brainstem circuits, ultimately resulting in ineffective motor output of the spinal pattern generator. Electrophysiological studies pointed to abnormalities of oscillatory activity in freezers that covered a broad frequency range including the theta, alpha, and beta bands. We explored muscular frequency domain activity with respect to freezing, and used deep brain stimulation to modulate these rhythms thereby (...) evaluating the supraspinal contributions to spinal motor neuron activity.MethodsWe analyzed 9 PD freezers and 16 healthy controls. We studied the patients after overnight withdrawal of dopaminergic medication with stimulation off, stimulation of the subthalamic nucleus or the substantia nigra pars reticulate, respectively. Patients performed a walking paradigm passing a narrow obstacle. We analyzed the frequency-domain spectra of the tibialis anterior and gastrocnemius muscles in ‘regular gait’ and during the ‘freezing’ episodes.ResultsIn stimulation off, PD freezers showed increased muscle activity of the alpha and low-beta band compared to HC in both TA and GA. This activity increase was present during straight walking and during the freezes to similar extent. STN- but not SNr-DBS decreased this activity and paralleled the clinical improvement of freezing.ConclusionWe found increased muscle activation of the alpha and lower beta band in PD freezers compared to HC, and this was attenuated with STN-DBS. Future studies may use combined recordings of local field potentials, electroencephalography, and electromyography to interrogate the supraspinal circuit mechanisms of the pathological activation pattern of the spinal pattern generator.

Ruth Millikan and others advocate theories which attempt to naturalize wide mental content (e.g. beliefs.

The exportation of Western biomedicine throughout the world has not resulted in a systematic homogenization of scientific ideology but rather in the proliferation of many forms and practices of biomedicine. Similarly, in the last decade, bioethics has become increasingly an international enterprise. Although there may be consensus regarding the inherent value of ethical discourse as it relates to health and medical care, there are disagreements about the nature and parameters of medical morality. This lack of consensus exists because our beliefs (...) about morality are culturally constituted, embedded in social, religious, and political ideologies that influence particular individuals and communities at specific historical moments.

This paper regards the plausibility of rejecting the scholastic claim that the “good” is a transcendental property of being—that ens et bonum convertuntur—onthe basis of two claims: Stephen Cahn’s claim that evil worlds created by an evil God are intrinsically plausible—i.e., that it is plausible to think of evil as a positive and instantiable property; and the claim that “evil is a primitive”—that is, that evil is a primary or basic ontological property. It argues that if an “ontological primitive” must (...) be a property which has no basic constituents other than itself—or whose definition cannot invoke concepts or constituents other than the primitive itself—evil itself cannot be considered a primitive. Nor can it be considered a positive property. (shrink)

Intellectual receptivity is both the prerequisite for objective human knowledge and the condition of possibility for all human knowledge. My arguments are cast in Thomistic terms. In the first part, I review the most important arguments with which Aquinas defends the receptivity of the human intellect, especially the argument from intellectual media and the argument from actualization. In the second part, I attempt to resolve the apparent contradictions involved in the claim that the intellect is receptive, contradictions that stem from (...) the fact that the intellect is an active potency (since its proper act is to reason) and receptivity is the act of a passive potency. In the final part,I argue that knowledge of the proper object of the human intellect (material singulars) is possible if and only if the human intellect is receptive. (shrink)

Robustly realistic metaphysical readings of Kant’s mature views have become popular in recent years, largely because of the apparent coherence of applying unschematized categories like that of causation to things in themselves. There is, however, an overlooked problem that arises even for robust realist readings that privilege unschematized categories. The problem is that Kant provides all the elements for what is now called a ‘debunking explanation’ of metaphysical representations of things in themselves. His account of the categories as arising from (...) mere forms of judgment, and being applied primarily for the unity of consciousness, is detached from the issue of whether there are causes among things in themselves. This detachment seems to imply that it would be a huge coincidence if unschematized categories corresponded to any such causes. After making this argument, using the category of causation as my central case, I consider three potential responses: that Kant’s account implicitly appeals to things in themselves’ causation, that Kant has a separate account of non-coincidental representation, and that Kant’s account is merely incomplete in a way that poses no debunking threat. None of these responses, I argue, are successful, so I conclude that either robustly realistic metaphysical readings are mistaken, or there is internal incoherence in Kant’s views. (shrink)

In this essay, I offer some of the reasons to think that Plato has a substantial contribution to make to contemporary thinking about moral education. To allow a sense of how wide the range of reasons is, I start by listing ten miscellaneous reasons that one can compellingly offer and some of which scholars *have* offered. Then I present my preferred reason, which involves a way of approaching Plato that is new and unorthodox. When you approach Plato this way, you (...) don't try to interpret him correctly. Instead, you use his writings simply as a tool for theorizing, and what you theorize about is how best to carry out the Socratic project of leading other people to self-examination. (shrink)

Socially responsible investments (SRI) suffer from a lack of investments from individual investors, despite their positive attitudes toward SRI. This attitude–behavior gap is a serious issue, as SRI is often perceived as a way to promote sustainable development. We investigate nudges, especially the default option, as a way to encourage SRI. In a pre-registered study conducted in October 2021 with 1050 US investors, we pit four nudges against one another to encourage individual investors to invest in SRI. All nudges significantly (...) increased investment in SRI compared with the control group. Making SRI the default option with frictions to opt-out is the most efficient intervention. This is closely followed by a default option without friction to opt out and option partitioning, which are not significantly different from each other. Precommitment, although statistically significant, has a modest effect on investment in SRI and is inferior to the other nudges. Overall, the two types of default as well as option partitioning are significant and impactful solutions for increasing investment in SRI. (shrink)

These essays, with one exception originally published in Philosophy & Public Affairs, consider the moral problems associated with improving the social and economic position of disadvantaged groups.

In response to Miranda Fricker's advocacy of a virtue of ‘reflexive critical openness’, I emphasise the importance of other virtues, such as loyalty, in evaluating an agent's response to testimony, and I query Fricker's claim that in certain circumstances agents can lack a means to correct their faulty evaluations of another's testimony.

Béatrice Longuenesse is one of the most important scholars of German philosophy in the past 50 years. In her earlier work, she shed light on the importance of subtle features of Kant’s and Hegel’s philosophical systems, and is largely responsible for a dramatic increase in depth in the work of younger scholars. In her more recent work, Longuenesse has built on doctrines concerning the self and self-consciousness from Kant and other philosophers, demonstrating the continued relevance of history of philosophy to (...) contemporary philosophy. This volume, as a part of Routledge’s series, Festschrifts in Philosophy, includes 14 original essays in honor of Longuenesse, alongside an autobiographical essay by Longuenesse herself. Contributors include many of Longuenesse’s long-time interlocutors as well as her former students. (shrink)
