This commentary compares clinical aspects of ketamine with the amphetamine model of schizophrenia. Hallucinations and loss of insight, associated with amphetamine, seem more schizophrenia-like. Flat affect encountered with ketamine is closer to the clinical presentation in schizophrenia. We argue that flat affect is not a sign of schizophrenia, but rather, a risk factor for chronic schizophrenia.

Burt C. Hopkins presents the first in-depth study of the work of Edmund Husserl and Jacob Klein on the philosophical foundations of the logic of modern symbolic mathematics. Accounts of the philosophical origins of formalized concepts—especially mathematical concepts and the process of mathematical abstraction that generates them—have been paramount to the development of phenomenology. Both Husserl and Klein independently concluded that it is impossible to separate the historical origin of the thought that generates the basic concepts of mathematics from (...) their philosophical meanings. Hopkins explores how Husserl and Klein arrived at their conclusion and its philosophical implications for the modern project of formalizing all knowledge. (shrink)

Individuals differ greatly in their ability to learn and navigate through environments. One potential source of this variation is “directional sense” or the ability to identify, maintain, and compare allocentric headings. Allocentric headings are facing directions that are fixed to the external environment, such as cardinal directions. Measures of the ability to identify and compare allocentric headings, using photographs of familiar environments, have shown significant individual and strategy differences; however, the neural basis of these differences is unclear. Forty-five college students, (...) who were highly familiar with a campus environment and ranged in self-reported sense-of-direction, underwent fMRI scans while they completed the Relative Heading task, in which they had to indicate the direction of a series of photographs of recognizable campus buildings (i.e., “target headings”) with respect to initial “orienting headings”. Large individual differences were found in accuracy and correct decision latencies, with gender, self-reported sense-of-direction, and familiarity with campus buildings all predicting task performance. Using linear mixed models, the directional relationships between headings and the experiment location also impacted performance. Structural scans revealed that lateral orbitofrontal and superior parietal volume were related to task accuracy and decision latency, respectively. Bilateral hippocampus and right presubiculum volume were related to self-reported sense-of-direction. Meanwhile, functional results revealed clusters within the superior parietal lobule, supramarginal gyrus, superior frontal gyrus, lateral orbitofrontal cortex, and caudate among others in which the intensity of activation matched the linear magnitude of the difference between the orienting and target headings. While the retrosplenial cortex and hippocampus have previously been implicated in the coding of allocentric headings, this work revealed that comparing those headings additionally involved frontal and parietal regions. These results provide insights into the neural bases of the variation within human orientation abilities, and ultimately, human navigation. (shrink)

The paper argues for three things. First, that the abstract concepts of ancient Greek and modern mathematics are fundamentally different. The general treatment of mathematical things in ancient Greek mathematics manifestly does not presuppose a general mathematical object, while in modern mathematics the generality of the method presupposes precisely such a general mathematical object. Two, that this difference in abstract concepts of mathematics makes a difference in our understanding of a discipline other than mathematics, specifically, in the discipline of history. (...) And, three, that what is at issue in this difference is whether it is necessary for human beings to understand themselves from the perspective of history in order to understand themselves properly as human.

The sociogenomics revolution is upon us, we are told. Whether revolutionary or not, sociogenomics is poised to flourish given the ease of incorporating polygenic scores (or PGSs) as “genetic propensities” for complex traits into social science research. Pointing to evidence of ubiquitous heritability and the accessibility of genetic data, scholars have argued that social scientists not only have an opportunity but a duty to add PGSs to social science research. Social science research that ignores genetics is, some proponents argue, at (...) best partial and likely scientifically flawed, misleading, and wasteful. Here, I challenge arguments about the value of genetics for social science and with it the claimed necessity of incorporating PGSs into social science models as measures of genetic influences. In so doing, I discuss the impracticability of distinguishing genetic influences from environmental influences because of non-causal gene–environment correlations, especially population stratification, familial confounding, and downward causation. I explain how environmental effects masquerade as genetic influences in PGSs, which undermines their raison d’être as measures of genetic propensity, especially for complex socially contingent behaviors that are the subject of sociogenomics. Additionally, I draw attention to the partial, unknown biology, while highlighting the persistence of an implicit, unavoidable reductionist genes versus environments approach. Leaving sociopolitical and ethical concerns aside, I argue that the potential scientific rewards of adding PGSs to social science are few and greatly overstated and the scientific costs, which include obscuring structural disadvantages and cultural influences, outweigh these meager benefits for most social science applications.

Hopkins begins his study with Plato's written and unwritten theories of eidê and Aristotle's criticism of both. He then traces Husserl's early investigations into the formation of mathematical and logical concepts, charting the critical necessity that leads from descriptive psychology to transcendentally pure phenomenology. An investigation of the movement of Husserl's phenomenology of transcendental consciousness to that of monadological intersubjectivity follows. Hopkins then presents the final stage of the development of Husserl's thought, which situates monadological intersubjectivity within the context of (...) the historical a priori constitutive of all meaning. An exposition of the unwarranted historical presuppositions that guide Heidegger's fundamental ontological and Derrida's deconstructive criticisms of Husserl's transcendental phenomenology concludes the book. By following Husserl's personal trajectory Hopkins is able to show the unity of Husserl's philosophical enterprise, challenging the prevailing view that Husserl's late turn to history is inconsistent with his earlier attempts to establish phenomenology as a pure science.

Solly Zuckerman’s work has been largely dismissed or marginalized by both historians of primatology and primatologists. This paper, using archival and published materials, re-examines both his life and his research into primate sexuality and sociology in the 1920s, endocrinology in the 1930s, and the effects of bomb blast in the 1940s. Despite the many flaws in his work, which is now largely outdated, his career reveals a great deal about the audiences for primatological knowledge in pre-war and wartime Britain; the (...) interlocking circles of the scientific community that impinged on primatology; and competing ideas of what constituted a scientifically correct methodology for the observation of primate behaviour. Also noted is the gap between Zuckerman’s self-presentation as the scourge of anthropomorphism and the anthropomorphism of his remarks in private notebooks. Although his work well illustrates familiar themes of patriarchy, military and colonialism in the history of primatology, it also suggests another, underexplored dimension of that science: primatology as an example of cross-species social interaction.

Behavioral genetic (BG) research has yielded many important discoveries about the origins of human behavior, but offers little insight into how we might improve outcomes. We posit that this gap in our knowledge base stems in part from the epidemiologic nature of BG research questions. Namely, BG studies focus on understanding etiology as it currently exists, rather than etiology in environments that could exist but do not as of yet (e.g., etiology following an intervention). Put another way, they focus exclusively (...) on the etiology of “what is” rather than “what could be”. The current paper discusses various aspects of this field-wide methodological reality, and offers a way to overcome it by demonstrating how behavioral geneticists can incorporate an experimental approach into their work. We outline an ongoing study that embeds a randomized intervention within a twin design, connecting “what is” and “what could be” for the first time. We then lay out a more general framework for a new field—experimental BGs—which has the potential to advance both scientific inquiry and related philosophical discussions. (shrink)

Uchiyama et al. propose a unified model linking cultural evolutionary theory to behavior genetics (BG) to enhance generalizability, enrich explanation, and predict how social factors shape heritability estimates. A consideration of culture evolution is beneficial but insufficient for purpose. I submit that their proposed model is underdeveloped and their emphasis on heritability estimates misguided. I discuss their ambiguous conception of culture, neglect of social structure, and the lack of a general theory in BG.

Charney argues that the presence of inherited epigenetic effects makes twin, family, and adoption studies obsolete. This argument relies on both a faulty characterization of these studies and indirect comparisons of DNA and factors. I argue that twin and family studies will in fact serve a necessary and vital role in the study of epigenetic and neogenetic processes.

The chapter discusses the founding and development up to the present day of the journal “Husserl Studies” and the history and purpose of the journal The New Yearbook for Phenomenology and Phenomenological Philosophy.

Two of Husserl’s most important, though fragmentary texts from the final phase of his thought, The Crisis of European Sciences and Transcendental Phenomenology and “The Origin of Geometry as an Intentional-Historical Problem,” focus on the themes of history and the life-world. It is well known that prior to these works Husserl sought to establish transcendental phenomenology as both a factually and an historically pure eidetic science. Thus the interpreter of the whole of Husserl’s thought is faced with the question of (...) whether his later focus on history and the life-world represents a significant departure from his previous thought. In what follows, I shall defend the thesis that it does not. Specifically, I shall argue that the completion of Husserl’s project of realizing the goal of First Philosophy in transcendental phenomenology renders necessary the turn both to history and to the life-world. In connection with this, I shall argue further that the peculiar phenomenological character of this necessity demands that the ‘concepts’ of history and life-world operative in Husserl’s last texts are taken to be inseparably rooted in a more original phenomenon. Husserl conceives this more original phenomenon as the crisis situation of the exemplars of European humanity, the philosophers, who, as the “functionaries of mankind” are faced with the “breakdown” situation of our time, with the “breakdown” of science itself.

Cesario provides a compelling critique of the use of experimental social psychology to explain real-world group disparities. We concur with his targeted critique and extend “the problem of missing information” to another common measures of bias. We disagree with Cesario's broader argument that the entire enterprise be abandoned, suggesting instead targeted utilization. Finally, we question whether the critique is appropriately directed at experimental social psychologists.

For centuries in the UK and elsewhere, charities have been widely regarded as admirable and virtuous organisations. Business corporations, by contrast, have been characterised in the popular imagination as entities that lack a capacity for moral judgement. Drawing on the philosophical literature on the moral agency of organisations, we examine how the law shapes the ability of charities and business corporations headquartered in England to exercise moral agency. Paradoxically, we find that charities are legally constrained in exercising moral agency in (...) ways in which business corporations are not. Implications for charities and business corporations are then explored. (shrink)

The article explores the relationship between the philosopher and historian of mathematics Jacob Klein’s account of the transformation of the concept of number coincident with the invention of algebra, together with Husserl’s early investigations of the origin of the concept of number and his late account of the Galilean impulse to mathematize nature. Klein’s research is shown to present the historical context for Husserl’s twin failures in the Philosophy of Arithmetic: to provide a psychological foundation for the proper concept of (...) number, and to show how this concept of number functions as the mathematical foundation of universal arithmetic. This context establishes that Husserl’s failures are ultimately rooted in the historical transformation of number documented in Klein’s research, from its premodern meaning as the unity of a multitude of determinate objects to its modern meaning as a symbolic representation with no immediate relation to a concrete multiplicity. The argum... (shrink)

Tolerancia, en nuestro caso, significa el derecho y obligación de la autoridad civil para determinar la filiación religiosa de sus súbditos. Filosóficamente considerada, significa la extensión de la libertad de conciencia de los individuos y los derechos del Estado para obligar a una uniformidad de fe. El hombre es un animal social, y el problema consecuente de los derechos de la persona para con la sociedad y los derechos correlativos de la sociedad con el individuo ha sido siempre una cuestión (...) espinosa. El ámbito de los derechos del Estado sobre la conciencia de sus súbditos, y especialmente por lo que se refiere al derecho de adorar a la Divinidad, ha sido extendido y restringido según los tiempos. Frecuentemente las opiniones son deformadas por los prejuicios, fenómeno comprensible si tenemos en cuenta que nada hay más precioso al hombre como su libertad de fe. En este punto el dedo del filósofo toca el mismo corazón del indocto, pues, aunque pocos pueden comprender la teoría sobre la tolerancia religiosa, todos pueden reconocer sus implicaciones prácticas.

De acuerdo con la así llamada concepción platonista de la naturaleza de las entidades matemáticas, las afirmaciones matemáticas son análogas a las afirmaciones acerca de objetos físicos reales y sus relaciones, con la diferencia decisiva de que las entidades matemáticas no son ni físicas ni espacio temporalmente individuales, y, por tanto, no son percibidas sensorialmente. El platonismo matemático es, por lo tanto, de la misma índole que el platonismo en general, el cual postula la tesis de un mundo ideal de (...) entidades –eídē– que a la vez están separadas (chōristón) y son el fundamento cognitivo y ontológico del mundo real de cosas físicas que poseen propiedades espacio-temporales. Mientras que la no-identidad entre la concepción platonista de las entidades matemáticas y el platonismo del Platón “histórico” es frecuentemente reconocida tácita o explícitamente tanto por sus defensores como por sus críticos, su conexión conla crítica del Aristóteles “histórico” a la filosofía de Platón frecuentemente no es reconocida. Este artículo llama la atención sobre la conexión de Aristóteles con el así llamado platonismo tradicionalmente concebido y reconstruye un aspecto crucial de su crítica a la tesis originaria del chōrismós platónico que se pierde de vista a menos que se reconozca el objetivo verdadero de su crítica, la descripción platónica igualmente originaria de los números eidéticos.---“The Source of Platonism in the Philosophy of Mathematics Revisited: Aristotle’s Critique of Eidetic Numbers”. According to the so-called Platonistic conception of the nature of mathematical entities, mathematical statements are analogous to statements about real physical objects and their relations, with the one decisive difference that mathematical entities are neither physical nor individuated spatio-temporally and, thus, not perceived sensuously. Mathematical Platonism is therefore of a piece with Platonism in general, which posits the thesis of an ideal world of entities –eídē– that are both separate (chōristón) from and the cognitive and ontological foundations of the real world of physical things possessing spatio-temporal properties. While the non-identity of the Platonistic conception of mathematical entities with the Platonism of the “historical” Plato is usually either tacitly or explicitly acknowledged by its defenders and critics alike, its connection with the “historical” Aristotle’s critique of Plato’s philosophy usually goes unacknowledged. This paper both calls attention to Aristotle’s connection with the so-called Platonism traditionally conceived and reconstructs a crucial aspect of his critique of the original Platonic chōrismós thesis, an aspect that is missed unless the true target of this critique, the equally original Platonic account of eidetic numbers, is recognized.
