Metaphysics and Natural Kinds: Slingshots, Fundamentality, and Causal Structure
My dissertation addresses a question relevant to metaphysics, philosophy of language, and philosophy of science: What are natural kinds? I explore a view that holds that natural kinds are complex, structural properties that involve causal structure. Causal structure describes the idea that for the many properties associated with natural kinds, these properties are nomically linked - that is causally connected - in such a way that the properties of non-natural kinds are not. After criticizing arguments in favor of a nominalist theory of kinds - one that holds that a natural kind just is to be identified with its class of instances - and after defending the notion of a complex structural property from several prominent objections posed by David Lewis, I apply a causal account of natural kinds to a set of problematic cases, paying special attention to isomeric kinds from chemistry
Complexity Begets Crosscutting, Dooms Hierarchy (Another Paper on Natural Kinds)
There is a perennial philosophical dream of a certain natural order for the natural kinds. The name of this dream is âthe hierarchy requirementâ (or âassumptionâ or âthesisâ). According to this postulate, proper natural kinds form a taxonomy which is both unique (i.e., there is only one taxonomy of such natural kinds) and traditional (i.e., said taxonomy consists of nested relations between specific and then more general kinds, each kind occupying one and only one particular place within that framework of relations). Here I demonstrate that complex scientific objects exist: objects which generate different systems of scientific classification, produce myriad legitimate alternatives amongst the nonetheless still natural kinds, and make the hierarchical dream impossible to realize, except at absurdly great cost. Philosophical hopes for a certain order in nature cannot be fulfilled. Natural kinds crosscut one another, ubiquitously so, and this crosscutting spells the end of the hierarchical dream

Megascopic Quantum Phenomena. A Critical Study of Physical Interpretations
A megascopic revalidation is offered providing responses and resolutions of
current inconsistencies and existing contradictions in present-day quantum
theory. As the core of this study we present an independent proof of the
Goldstone theorem for a quantum field formulation of molecules and solids.
Along with phonons two types of new quasiparticles appear: rotons and
translons. In full analogy with Lorentz covariance, combining space and time
coordinates, a new covariance is necessary, binding together the internal and
external degrees of freedom, without explicitly separating the centre-of-mass,
which normally applies in both classical and quantum formulations. The
generally accepted view regarding the lack of a simple correspondence between
the Goldstone modes and broken symmetries, has significant consequences: an
ambiguous BCS theory as well as a subsequent Higgs mechanism. The application
of the archetype of the classical spontaneous symmetry breaking, i.e. the
Mexican hat, as compared to standard quantum relations, i.e. the Jahn-Teller
effect, superconductivity or the Higgs mechanism, becomes a disparity. In
short, symmetry broken states have a microscopic causal origin, but transitions
between them have a teleological component. The different treatments of the
problem of the centre of gravity in quantum mechanics and in field theories
imply a second type of Bohr complementarity on the many-body level opening the
door for megascopic representations of all basic microscopic quantum axioms
with further readings for teleonomic megascopic quantum phenomena, which have
no microscopic rationale: isomeric transitions, Jahn-Teller effect, chemical
reactions, Einstein-de Haas effect, superconductivity-superfluidity, and
brittle fracture.Comment: 117 pages, 17 sections, final revised version from 20 May 2019 but

Image and Evidence: The Study of Attention through the Combined Lenses of Neuroscience and Art
: Levy, EK 2012, âAn artistic exploration of inattention blindnessâ, in Frontiers Hum Neurosci, vol. 5, ISSN=1662-5161.Full version unavailable due to 3rd party copyright restrictions.This study proposed that new insights about attention, including its phenomenon and pathology, would be provided by combining perspectives of the neurobiological discourse about attention with analyses of artworks that exploit the constraints of the attentional system. To advance the central argument that art offers a training ground for the attentional system, a wide range of contemporary art was analysed in light of specific tasks invoked. The kinds of cognitive tasks these works initiate with respect to the attentional system have been particularly critical to this research. Attention was explored within the context of transdisciplinary art practices, varied circumstances of viewing, new neuroscientific findings, and new approaches towards learning. Research for this dissertation required practical investigations in a gallery setting, and this original work was contextualised and correlated with pertinent neuroscientific approaches. It was also concluded that art can enhance public awareness of attention disorders and assist the public in discriminating between medical and social factors through questioning how norms of behaviour are defined and measured. This territory was examined through the comparative analysis of several diagnostic tests for attention deficit hyperactivity disorder (ADHD), through the adaptation of a methodology from economics involving patent citation in order to show market incentives, and through examples of data visualisation. The construction of an installation and collaborative animation allowed participants to experience first-hand the constraints on the attentional system, provoking awareness of our own ânormalâ physiological limitations. The embodied knowledge of images, emotion, and social context that are deeply embedded in art practices appeared to be capable of supplementing neuroscienceâs understanding of attention and its disorders
From Hyperspace to Mental Hygiene: A. T. Schofieldâs Conception of Mind and Spirit
This paper explores the intersection of psychology and religion in late-Victorian Britain through the life of medical psychologist and lay religious author, Dr. Alfred Taylor Schofield. Extending the work of recent scholarship on the contested nature of nineteenth-century sciences of mind, this study focuses on the interplay between popular and professional communities engaged in discourse over mind/body issues and the unconscious mind, and the relevance of these contemporary topics to debates over the certainty of natural versus supernatural knowledge.
In the period between 1890 and 1910, when psychology (âthe new psycho-physiology,â in Britain) emerged as an autonomous scientific discipline separate from its past disciplinary home within moral philosophy, the application of psychology within medicine (early psychiatry) encountered institutional and philosophical impediments that hindered the incorporation of psychodynamic theories and new psychotherapeutic regimens into medical curriculum and clinical practice. This paper examines the rising cultural phenomena of faith healing, the responses of religious and medical communities to popular healing movements, and the implications that these movements had for both the development of early psychiatry as well as for contemporary transformations in religious sensibilities.
Utilizing the unique position of A.T. Schofield, who straddled a popular-professional divide in mediating between medical and lay religious communities, this paper seeks to explain how the proliferation of popular healing movements provoked professional interest in new psychotherapies while psycho-physiological explanations of faith healing altered lay religious understandings of âmiraclesâ and transcendental knowledge
