The orphans of Romania were participants in what is sometimes called “the forbidden experiment”: depriving human infants of intimacy, affection, and human contact is an inhuman practice. It is an experiment which no ethical researcher would set out to do. This paper examines historical data, case histories, and research findings which deal with early deprivation and performs a phenomenological analysis of deprivation phenomena as they impact emotional and physical development. A key element of deprivation is the absence of intimate relationships (...) with other human beings. However, the absence of intimacy impacts not only the social/emotional abilities of infants, but their very ability to perceive the world. Philosophically and from a radically Merleau-Pontean perspective, the intimate face of the other appears to be a world opening event for the child. Its absence has a profound impact on the child’s experience of embodiment, coexistence, spatiality, temporality, and language. When seen through early deprivation, intimacy appears as a necessary foundation for establishing the transcendence of the world beyond perceptual presence, and it provides the possibility for language, culture, and history.

Psychiatric diagnostic covariation suggests that the underlying structure of psychopathology is not one of circumscribed disorders. Quantitative modeling of individual differences in diagnostic patterns has uncovered several broad domains of mental disorder liability, of which the Internalizing and Externalizing spectra have garnered the greatest support. These dimensions have generally been estimated from lifetime or past-year comorbidity patters, which are distal from the covariation of symptoms and maladaptive behavior that ebb and flow in daily life. In this study, structural models are (...) applied to daily diary data ( Median = 94 days) of maladaptive behaviors collected from a sample ( N = 101) of individuals diagnosed with personality disorders (PDs). Using multilevel and unified structural equation modeling, between-person, within-person, and person-specific structures were estimated from 16 behaviors that are encompassed by the Internalizing and Externalizing spectra. At the between-person level (i.e., individual differences in average endorsement across days) we found support for a two-factor Internalizing–Externalizing model, which exhibits significant associations with corresponding diagnostic spectra. At the within-person level (i.e., dynamic covariation among daily behavior pooled across individuals) we found support for a more differentiated, four-factor, Negative Affect-Detachment-Hostility-Disinhibition structure. Finally, we demonstrate that the person-specific structures of associations between these four domains are highly idiosyncratic. (shrink)

We show that the identity bounded Turing degrees of computably enumerable sets are not dense.

Accumulating evidence indicates that simulated natural settings can engage mechanisms that promote health. Simulations offer alternatives to actual natural settings for populations unable to travel outdoors safely; however, few studies have contrasted the effects of simulations of natural settings to their actual outdoor counterparts. We compared the impacts of simulated and actual natural settings on positive and negative affect (mood) levels using a pooled sample of participants enrolled in extant experimental studies. Relevant articles were identified from a review of research (...) published/in press by March 2020 and updated during the peer review of the current study. Of 16 articles identified, 6 met the inclusion criteria and administered a single cross-cutting, standardized instrument [the Positive and Negative Affect Schedule (PANAS)] before and after exposure. Random effects meta-analysis of pooled effects showed that positive affect increased in the actual settings but not in their simulated counterparts (Hedge's g = 0.87; 95% CI, 0.54, 1.20). We observed little difference in effects on negative affect change scores ( g = −0.28; 95% CI, −0.62, 0.06), with studies generally showing reductions in negative affect in both settings. Further research with additional populations, settings, antecedent conditions, and durations would provide a more robust understanding of differences in effects between these two ways to enhance mood by viewing nature.

Interpretations abound about Husserl’s understanding of the relationship between veridical perceptual experience and hallucination. Some read him as taking the two to share the same distinctive essential nature, like contemporary conjunctivists. Others find in Husserl grounds for taking the two to fall into basically distinct categories of experience, like disjunctivists. There is ground for skepticism, however, about whether Husserl’s view could possibly fall under either of these headings. Husserl, on the one hand, operates under the auspices of the phenomenological reduction, (...) abstaining from use of any epistemic commitments about mind-transcendent reality, whereas conjunctive and disjunctive accounts of perceptual experience, on the other hand, are both premised on some form of metaphysical realism. There seems to be a basic incompatibility between the former approach and the latter. I examine this line of thinking and argue that the incompatibility is only apparent. (shrink)

Prior research has demonstrated that antisocial behavior, substance-use disorders, and personality dimensions of aggression and impulsivity are indicators of a highly heritable underlying dimension of risk, labeled externalizing. Other work has shown that individual trait constructs within this psychopathology spectrum are associated with reduced self-monitoring, as reflected by amplitude of the error-related negativity (ERN) brain response. In this study of undergraduate subjects, reduced ERN amplitude was associated with higher scores on a self-report measure of the broad externalizing construct that links (...) these various indicators. In addition, the ERN was associated with a response-locked increase in anterior theta (4–7 Hz) oscillation; like the ERN, this theta response to errors was reduced among high-externalizing individuals. These findings suggest that neurobiologically based deficits in endogenous action monitoring may underlie generalized risk for an array of impulse-control problems. (shrink)

Rule of law and constitutionalist ideals are understood by many, if not most, as necessary to create a just political order. Defying the traditional division between normative and positive theoretical approaches, this book explores how political reality on the one hand, and constitutional ideals on the other, mutually inform and influence each other. Seventeen chapters from leading international scholars cover a diverse range of topics and case studies to test the hypothesis that the best normative theories, including those regarding the (...) role of constitutions, constitutionalism and the rule of law, conceive of the ideal and the real as mutually regulating.

A number of philosophers have held that we visually experience objects’ occluded parts, such as the out-of-view exterior of a voluminous, opaque object. That idea is supposed to be what best explains the fact that we see objects as whole or complete despite having only a part of them in view at any given moment. Yet, the claim doesn’t express a phenomenological datum and the reasons for thinking we do experience objects’ occluded parts, I argue, aren’t compelling. Additionally, I anticipate (...) and reply to attempts to salvage the idea by appeal to perceptual expectation and amodal completion. Lastly, I address potential concerns that the only way to capture the phenomenal character of perceiving voluminous objects is to say experience outstrips what’s in view, providing a description of such experience without any implication of that idea.

Levinas is usually discussed as a philosopher wrestling with the nature of our experience of others, ethical obligation, and the divine. Unlike other phenomenologists, such as Husserl and Heidegger, he is not often mentioned in discussions about issues in philosophy of mind. His work in that area, especially on perception, is underappreciated. He gives an account of the nature of perceptual experience that is remarkable both in how it departs from that of others in the phenomenological tradition and for how (...) it fits in among presently available views about the nature of perceptual experience, namely, as a form of naïve realism.

A quantum theory of the photon is developed in a natural manner. Newton-Wigner and Wightman demonstrated that the photon could not be strictly localized according to natural criteria. These investigations involved the identification of an elementary system with a uirrep of the Poincare group. We identify a particle with the localized measurement of the states satisfying the uirrep. In the case of zero mass and unit spin, the photon is identified with those components of the state that can be localized. (...) A c-number four-vector potential and Lorentz condition are derived from the relativistic wave equation. The Wightman localization is demonstrated for the three independent space components of the vector potential, and the photon is identified with these components. A position operator and probability density follow immediately from the localization. A consequence of the subjective definition of a photon is that the transformations of the vector potential are unitary, and hence the unitary scalar product can be obtained for the four-vector potential. A Hilbert space is defined for the three space components of the vector potential. A position operator and probability density are derived from the scalar product, which compare directly with those obtained from the localization and the non-relativistic theory. As the longitudinal and scalar polarizations do not contribute to the measured transition probability, they are considered virtual. Lastly, a conserved four-vector current is derived from the scalar product. The possibility of observing a strict localization of the photon in the laboratory is suggested. (shrink)

Hegel's influence on post-Hegelian philosophy is as profound as it is ambiguous. Modern philosophy is philosophy after Hegel. Taking leave of Hegel's system appears to be a common feature of modern and post-modern thought. One could even argue that giving up Hegel's claim of totality defines philosophy after Hegel. Modern and post-modern philosophies are philosophies of finitude: Hegel's philosophy cannot be repeated. However, its status as a negative backdrop for modern and post-modern thought already shows its pervasive influence. Precisely in (...) its criticism of Hegel, modern thought is bound up with his thinking. (shrink)

The relation of genetic phenomenology and the project of phenomenological reduction is the primary concern of this paper. Despite Husserl’s occasional loose references to “the” reduction, performing the reduction actually refers to numerous interrelated techniques. I want here to delve into these intricacies with the aim of determining the place of genetic phenomenology within the whole of phenomenological technique. It will be necessary to both state in general terms what the aim of the reduction is and what the different “ways” (...) to the reduction are before highlighting their inadequacy for dealing with genetic matters, which then brings us face to face with the underexplored possibility that there might be a peculiar novel from of reduction or transformation of the reduction that is needed to deal with genesis on properly transcendental ground. Following this line of thought, I attempt to elaborate a way into genetic phenomenology, which, I suggest, begins to appear most clearly in Husserl’s later reflections on “abnormal” forms of consciousness.
