This document is a set of notes I took on QFT as a graduate student at the University of Pennsylvania, mainly inspired in lectures by Burt Ovrut, but also working through Peskin and Schroeder (1995), as well as David Tong’s lecture notes available online. They take a slow pedagogical approach to introducing classical field theory, Noether’s theorem, the principles of quantum mechanics, scattering theory, and culminating in the derivation of Feynman diagrams.

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.

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)

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.

ABSTRACTThis is an account of the emancipatory struggle that faces agents who seek to change the oppressive social structures associated with neo-liberalism. We begin by ‘digging amongst the bones’ of the calls for resistance that have been declared dead or assimilated/co-opted by neoliberal theorists. This leads us to unearth, then utilize, Paulo Freire’s Pedagogy of the Oppressed, Steve Biko’s Black Consciousness and Shiv Visvanathan's ideas; which are examples of Roy Bhaskar’s transformative dialectic. We argue, using examples, that cognitive justice – (...) a concept common to each of our chosen theorists – is vital in enabling emancipatory social learning. By embracing cognitive justice, the agents gained confidence, which led to their increased ability to champion community and non-academic knowledge. It also uncovered structural tensions – attendant in neoliberalism – around privilege. By articulating these tensions, the participants were able to ‘come closer together’. Such processes, initiated by ensuring cognitive justice, are possible steps in achieving universal solidarity; which is likely to be a necessary step along the path of achieving emancipation.

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.

This book examines Augustine's description of the actually existing world, especially that aspect most important for the human pursuit of happiness: the human being and God. It begins with an overview of the characteristics of the human individual and the context in which they must live out their lives, a context dominated by two seemingly contradictory realities: the existence of God and the existence of evil.

God deserves obedience simply because he’s God—or does he? Inspired by a passion for biblical as well as constitutional scholarship, in this bold exploration Yale Law Professor Robert A. Burt conceptualizes the political theory of the Hebrew and Christian Bibles. God’s authority as expressed in these accounts is not a given. It is no less inherently problematic and in need of justification than the legitimacy of secular government. In recounting the rich narratives of key biblical figures—from Adam and Eve (...) to Noah, Cain, Abraham, Moses, Job, and Jesus—In the Whirlwind paints a surprising picture of the ambivalent, mutually dependent relationship between God and his peoples. Taking the Hebrew and Christian Bibles as a unified whole, Burt traces God’s relationship with humanity as it evolves from complete harmony at the outset to continual struggle. In almost every case, God insists on unconditional obedience, while humanity withholds submission and holds God accountable for his promises. Contemporary political theory aims for perfect justice. The Bible, Burt shows, does not make this assumption. Justice in the biblical account is an imperfect process grounded in human—and divine—limitation. Burt suggests that we consider the lessons of this tension as we try to negotiate the power struggles within secular governments, and also the conflicts roiling our public and private lives.

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)

The problem of ‘collective unity’ in the transcendental philosophies of Kant and Husserl is investigated on the basis of number’s exemplary ‘collective unity’. To this end, the investigation reconstructs the historical context of the conceptuality of the mathematics that informs Kant’s and Husserl’s accounts of manifold, intuition, and synthesis. On the basis of this reconstruction, the argument is advanced that the unity of number – not the unity of the ‘concept’ of number – is presupposed by each transcendental philosopher in (...) their accounts of the transcendental foundation of manifold, intuition, and synthesis. This presupposition is ultimately traced to Kant’s and Husserl’s responses to Hume’s philosophy of human understanding and the critical limits of what Kant calls the ‘qualitative’ unity of transcendental consciousness. These critical limits are exposed in both philosophers’ attempts to account for that ‘qualitative’ unity on the basis of the ‘quantitative’ unity of number. (shrink)

Several interesting and important quantum field theories must contain the coupling constant in the boundary conditions. The theories considered include quantum electrodynamics of spin-1/2 fermions and gauge field theories.

In this response, I focus on clarifying my arguments, highlighting consensus, and addressing competing views about the utility of polygenic scores (PGSs) for social science. I also discuss an assortment of expansions to my arguments and suggest alternative approaches. I conclude by reiterating the need for caution and appropriate scientific skepticism.

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.

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.

James F. Sheridan Allegheny College As we come to the end of the century, an attentive student of con temporary European philosophy will no doubt be startled by a volume titled Husserl in Contemporary Context. Such philosophers are most likely to believe that Hussed has now been declared II classical" rather than a contemporary thinker or, worse, simply old fashioned. Access to Hussed today will most likely come through the allegedly definitive critiques of his work by Heidegger and Derrida and (...) to a lesser extent through the readings of his work by Levinas and Merleau Ponty although Merleau-Ponty himself has been declared old fashioned by some postmodems. Hence, if by II contemporary" one understands the problematic set by the work of the late Heidegger, Derrida, Foucault, et. al., Hussed's work seems strange indeed in such a contemporary context, seems better understood as the last gasp of philosophy dominated by metaphysics and thus fit only for inclusion in courses in the history of philosophy.

I compare Plato’s and Husserl’s accounts of the non-original appearance and the original with a focus on their methodologies for distinguishing between them and the phenomenological—i.e., the answer to the question of the what and how of their appearance—criteria that drive their respective methodologies. I argue that Plato’s dialectical method is phenomenologically superior to Husserl’s reflective method in the case of phantasmata that function as apparitions. Plato’s method has the capacity to discern the apparition on the basis of criteria that (...) appeal solely to its appearance, whereas Husserl’s method presupposes a non-apparent primitive distinction between the original qua primal impression and the phantasm as its reproductive modification. On the basis of Plato’s methodological superiority in this regard, I sketch a reformulation of the Husserlian approach to appearances guided by the original interrogative context of Plato’s dialectical account of the distinction between true and false appearances, eikones and phantasmata.
