The Forgetting Of Fire: An Archaeology Of Technics, Thomas A. Doerksen

Electronic Thesis and Dissertation Repository

This dissertation applies the methods of Bachelard and Foucault to key moments in the development of science. By analyzing the attitudes of four figures from four different centuries, it shows how epistemic attitudes have shifted from a participation in non-human, natural realities to a construction of human-centred technologies. The idea of an epistemic attitude is situated in reference to Foucault’s concept of the episteme and his method of archaeology; an attitude is the institutionally-situated and personally-enacted comportment of an epistemic agent toward an object of knowledge. This line of thought is pursued under the theme of elemental fire, which begins …

A Critical Phenomenological Inquiry Into Disabled Embodiment And Identity, Heather Twele

Electronic Thesis and Dissertation Repository

This thesis uses critical phenomenology to investigate disabled embodiment and identity. I argue that (in)accessible subjective accounts of disability experience reveal disability to be a unique form of ever-changing embodiment: disability is the lived experience of a critical phenomenology. I turn to eclectic art, film, and poetry case studies involving a medical, surgical gaze to explore how ableist, sexist, and racist systems structure daily experience, forcing disabled people who “misfit” to analyze and confront systems of oppression, exclusion, and stigmatization. Disability experience challenges and resists ableist binaries of ability/disability, well/unwell, subject/object, mind/body, and inside/outside. The interdependence of these fluid, intertwining …

Causal Variable Choice, Interventions, And Pragmatism, Zili Dong

Electronic Thesis and Dissertation Repository

The past century has witnessed numerous methodological innovations in probabilistic and statistical methods of causal inference (e.g., the graphical modelling and the potential outcomes frameworks, as introduced in Chapter 1). These innovations have not only enhanced the methodologies by which scientists across diverse domains make causal inference, but they have also made a profound impact on the way philosophers think about causation. The philosophical issues discussed in this thesis are stimulated and inspired by these methodological innovations.

Chapter 2 addresses the question of how the holding of screening-off conditions for a causal model depends on the choice of variables. As …

On Powerful Qualities, Dean J. Morales

Electronic Thesis and Dissertation Repository

The present work is a critical examination of the Powerful Qualities Ontology. Categoricalism affirms that intrinsic properties are quiddistic or qualitative in nature, and Pure Powers Theory affirms that they are by nature powerful. The Powerful Qualities Ontology, though, affirms that intrinsic properties are both qualitative and powerful, and that by being a more robust ontology than both Categoricalism and Pure Powers Theory, it promises to account for more phenomena and solve more problems than these rival theories. Despite its advantages, however, I challenge the feasibility of the Powerful Qualities Ontology. In chapter 1, I define important terms and provide …

Dissolving Nature/Nurture: Development As Coupled Interaction, Derek E. Oswick

Electronic Thesis and Dissertation Repository

For many, the Nature/Nurture approach to development is a quaint figment of the past. We have moved on, one might think; everyone thinks that both categories are important for development, not merely one. The reality, however, is not so simple. In this dissertation, I argue that contemporary biology has not succeeded in getting out from under the shadow of Nature/Nurture, despite everyone being some sort of interactionist about development. The central aim of my project is to offer a form of developmental interactionism worth having, which succeeds in shedding the pernicious aspects of Nature/Nurture. I begin by giving an overview …

Effective Field Theories: A Philosophical Appraisal, Dimitrios Athanasiou

Electronic Thesis and Dissertation Repository

The word “effective” has become the standard label attached to scientific theories these days. An effective theory allows us to make accurate predictions about a physical system at a certain (energy, length) scale while being largely ignorant of the details at more fundamental levels. One does not need to know anything about the deeper, quantum structure of water molecules to describe the macroscopic behaviour of waves or water in a glass. Although effective descriptions so broadly construed have been part of research in physics since the earliest stages of modern science, it is particle physics that has most clearly relied …

Theories: Reconsidering Ramsey In The Philosophy Of Science, John D. Lehmann

Electronic Thesis and Dissertation Repository

This work is an analysis of F. P. Ramsey's philosophy of science. Twentieth-century philosophy of science was marked by attempts to consider the relation between scientific theories and our knowledge of the empirical world through considerations of abstract mathematical structure. Such considerations led Bertrand Russell to an account of the relation between our theoretical picture of the world and its real nature as a relation of structural similarity. Subsequently, Max Newman gave what has become a well-known logico-mathematical objection to this account. William Demopoulos recently showed that Newman's problem applied not only to Russell's realist account, but also to a …

Back To The Beginning: An Empiricist Defense Of Scientific Stories About The Past, Craig William Fox

Electronic Thesis and Dissertation Repository

The Earth has not always been accompanied by its celestial partner, the Moon. In fact, the Moon was acquired by the Earth about 100 million years after the start of the solar system. It was acquired in the aftermath of a massive collision between the Earth and another planet, dubbed “Theia,” the mythological mother of the Greek goddess of the Moon. Most of the iron-rich cores of Earth and Theia merged almost immediately, while the rest of the two planets vaporized. Some of the impact ejecta was lost, but enough remained in gravitationally bound orbit around what was then $ …

Resonance, A Step Towards A Fluency For Complexity: The Science, Language, And Epistemology Of Gregory Bateson, Won Jeon

Electronic Thesis and Dissertation Repository

This thesis confronts the urgency with which new language and vocabulary is required to move beyond linear assumptions in mainstream science and humanities, as well as global policy making. I examine Gregory Bateson’s body of work in history and philosophy of science, psychiatry and psychotherapy, anthropology, biology and ecology designed to communicate the necessarily interdisciplinary consideration for a nonlinear and recursive investigation of the self, other, and environment. Such intellectual forays cannot be dismissed as non-scientific. I offer definitions and contextualizations of key terms derived from cybernetics, new materialisms, and posthumanism (such as emergence, process, paradox, metaphor, fractality) to speak …

In Search Of Psychiatric Kinds: Natural Kinds And Natural Classification In Psychiatry, Nicholas Slothouber

Electronic Thesis and Dissertation Repository

In recent years both philosophers and scientists have asked whether or not our current kinds of mental disorder—e.g., schizophrenia, depression, bipolar disorder—are natural kinds; and, moreover, whether or not the search for natural kinds of mental disorder is a realistic desideratum for psychiatry. In this dissertation I clarify the sense in which a kind can be said to be “natural” or “real” and argue that, despite a few notable exceptions, kinds of mental disorder cannot be considered natural kinds. Furthermore, I contend that psychopathological phenomena do not cluster together into kinds in the way that paradigmatic natural kinds (e.g., chemical …

Theory Construction In High-Energy Particle Physics, Adam Koberinski

Electronic Thesis and Dissertation Repository

Science is a process, through which theoretical frameworks are developed, new phenomena defined and discovered, and properties of entities tested. The goal of this dissertation is to illustrate how high-energy physics exemplified the process of theory construction from the 1950s to 1970s, and the promising ways in which it can continue to do so today. The lessons learned from the case studies examined here can inform future physics, and may provide methodological clues as to the best way forward today. I examine the discovery of parity nonconservation in weak interactions, the emergence of Yang-Mills theories as the foundation of the …

Rethinking Individuality In Quantum Mechanics, Nathan Moore

Electronic Thesis and Dissertation Repository

One recent debate in philosophy of physics has centered whether quantum particles are individuals or not. The received view is that particles are not individuals and the standard methodology is to approach the question via the structure of quantum theory. I challenge both the received view and the standard methodology. I contend not only that the structure of quantum theory is not the right place to look for conditions of individuality that quantum particles may or may not satisfy, but also that there is an important role for traditional metaphysics to play. Consequently, my work brings together the philosophy of …

On Separating The Wheat From The Chaff: Surplus Structure And Artifacts In Scientific Theories, Marie Gueguen

Electronic Thesis and Dissertation Repository

Although logical empiricism is now mostly decried, their naturalist claim that the content of a theory can be read off from its structure, without any philosophical considerations needed, still supports traditional strategies to escape cases of underdetermination. The appeal to theoretical equivalence or to theoretical virtues, for instance, both assume that there is a neutral standpoint from which the structure of the theories can be analyzed, the physically relevant from the superfluous separated, and a comparison made between their theoretical content and virtues. In my dissertation, I examine the presuppositions upon which such strategies depend. I argue that the methodological …

Computing, Modelling, And Scientific Practice: Foundational Analyses And Limitations, Filippos A. Papagiannopoulos

Electronic Thesis and Dissertation Repository

This dissertation examines aspects of the interplay between computing and scientific practice. The appropriate foundational framework for such an endeavour is rather real computability than the classical computability theory. This is so because physical sciences, engineering, and applied mathematics mostly employ functions defined in continuous domains. But, contrary to the case of computation over natural numbers, there is no universally accepted framework for real computation; rather, there are two incompatible approaches --computable analysis and BSS model--, both claiming to formalise algorithmic computation and to offer foundations for scientific computing.

The dissertation consists of three parts. In the first part, we …

A Practical And Practice-Sensitive Account Of Science As Problem-Solving, Frédéric-Ismaël Banville

Electronic Thesis and Dissertation Repository

Philosophers of science have recently begun to pay more attention to scientific practice, moving away from the discipline’s focus on theories. The creation of the Society for Philosophy of Science in Practice in 2006, as well as the emergence of scholarship on experimental practice (e.g. Sullivan 2009; 2010; 2016) as well as on the tools scientists use to construct explanations and theories (e.g. Feest 2011) all point to a disciplinary shift towards a more practice-conscious philosophy of science. In addition, scholars are realizing the potential social relevance of philosophy of science and identifying the obstacles that stand in the way …

A Pluralism Worth Having: Feyerabend's Well-Ordered Science, Jamie Shaw

Electronic Thesis and Dissertation Repository

The goal of this dissertation is to reconstruct, critically evaluate, and apply the pluralism of Paul Feyerabend. I conclude by suggesting future points of contact between Feyerabend’s pluralism and topics of interest in contemporary philosophy of science. I begin, in Chapter 1, by reconstructing Feyerabend’s critical philosophy. I show how his published works from 1948 until 1970 show a remarkably consistent argumentative strategy which becomes more refined and general as Feyerabend’s thought matures. Specifically, I argue that Feyerabend develops a persuasive case against rationalism, or the thesis that there exist normative and exclusive rules of scientific rationality. In Chapter …

Evidence In Neuroimaging: Towards A Philosophy Of Data Analysis, Jessey Wright

Electronic Thesis and Dissertation Repository

Neuroimaging technology is the most widely used tool to study human cognition. While originally a promising tool for mapping the content of cognitive theories onto the structures of the brain, recently developed tools for the analysis, handling and sharing of data have changed the theoretical landscape of cognitive neuroscience. Even with these advancements philosophical analyses of evidence in neuroimaging remain skeptical of the promise of neuroimaging technology. These views often treat the analysis techniques used to make sense of data produced in a neuroimaging experiment as one, attributing the inferential limitations of analysis pipelines to the technology as a whole. …

Species Pluralism: Conceptual, Ontological, And Practical Dimensions, Justin Bzovy

Electronic Thesis and Dissertation Repository

Species are central to biology, but there is currently no agreement on what the adequate species concept should be, and many have adopted a pluralist stance: different species concepts will be required for different purposes. This thesis is a multidimensional analysis of species pluralism. First I explicate how pluralism differs monism and relativism. I then consider the history of species pluralism. I argue that we must re-frame the species problem, and that re-evaluating Aristotle's role in the histories of systematics can shed light on pluralism. Next I consider different forms of pluralism: evolutionary and extra-evolutionary species pluralism, which differ in …

Similarity, Adequacy, And Purpose: Understanding The Success Of Scientific Models, Melissa Jacquart

Electronic Thesis and Dissertation Repository

A central component to scientific practice is the construction and use of scientific models. Scientists believe that the success of a model justifies making claims that go beyond the model itself. However, philosophical analysis of models suggests that drawing inferences about the world from successful models is more complex. In this dissertation I develop a framework that can help disentangle the related strands of evaluation of model success, model extendibility, and the ability to draw ampliative inferences about the world from models.

I present and critically assess two leading accounts of model assessment, arguing that neither is sufficient to provide …

The Entelechial Thinker In Space: ‘Worlds Within Worlds’ In Durrell, Flaubert, And Carroll, Sheena M. Jary

Electronic Thesis and Dissertation Repository

This thesis argues that the interior space of each individual mind has infinite potentiality to do or create x new reality in one’s life via possible worlds. I use Lawrence Durrell’s short story “Zero” (1939), Gustave Flaubert’s “Un coeur simple” (1877), and Lewis Carroll’s Alice’s Adventures in Wonderland (1865) as literary representations of how readers outside of the literary text share an unbreakable bond with universal space. I discuss the infinite potentiality of the finite being, and the experiential data in the process of entelechy, or epistemological maturation of the mind. I bring Leibniz’s theory of the continuum of infinitesimals …

Assessing Decision-Making Capacity After Severe Brain Injury, Andrew Peterson

Electronic Thesis and Dissertation Repository

Severe brain injury is a leading cause of death and disability. Following severe brain injury diagnosis is difficult and errors frequently occur. Recent findings in clinical neuroscience may offer a solution. Neuroimaging has been used to detect preserved cognitive function and awareness in some patients clinically diagnosed as being in a vegetative state. Remarkably, neuroimaging has also been used to communicate with some vegetative patients through a series of yes/no questions. Some have speculated that, one day, this method may allow severely brain-injured patients to make medical decisions. Yet, skepticism is rife, due in part to the inherent difficulty of …

The Constellations Of Empiricism, New Science, And Mind In Hobbes, Locke, And Hume, Lisa Pelot

Electronic Thesis and Dissertation Repository

In this thesis, positive and negative tensions among the “unit-ideas” of New Science and empiricism are explored as they relate to explanations of aspects of mind in the Modern period. Some constellations of ideas are mutually supporting, and provide fruitful discussion on how mind can fit into the natural world. This project aims to clarify the adequacy of this type of framework in accommodating and explaining mind, and aspects of mind. I proceed by analyzing key texts via the “unit-ideas” of New Science and empiricism. The three central chapters are case studies, looking at Hobbes, Locke, and Hume. Each chapter …

Evaluating The Quantum Postulate In The Context Of Pursuit, Molly M. Kao

Electronic Thesis and Dissertation Repository

The purpose of this dissertation is to contribute to our understanding of scientific theory pursuit by providing a detailed case study on the development of early quantum theory, from roughly 1900 to 1916.

I first elaborate on why this case should be considered an instance of piecemeal pursuit by presenting the historical quantum conjectures that were being used in different contexts. These conjectures gave varied interpretations of quantization. By comparing these conjectures, I identify a general quantum postulate that captures the underlying assumption common to all the cases. I argue that it is possible to consider a general postulate about …

On The Role Of Mathematics In Scientific Representation, Saad Anis

Electronic Thesis and Dissertation Repository

In this dissertation, I consider from a philosophical perspective three related questions concerning the contribution of mathematics to scientific representation. In answering these questions, I propose and defend Carnapian frameworks for examination into the nature and role of mathematics in science.

The first research question concerns the varied ways in which mathematics contributes to scientific representation. In response, I consider in Chapter 2 two recent philosophical proposals claiming to account for the explanatory role of mathematics in science, by Philip Kitcher, and Otavio Bueno and Mark Colyvan. My novel and detailed critique of these accounts shows that they are too …

Probabilistic Reasoning In Cosmology, Yann Benétreau-Dupin

Electronic Thesis and Dissertation Repository

Cosmology raises novel philosophical questions regarding the use of probabilities in inference. This work aims at identifying and assessing lines of arguments and problematic principles in probabilistic reasoning in cosmology.

The first, second, and third papers deal with the intersection of two distinct problems: accounting for selection effects, and representing ignorance or indifference in probabilistic inferences. These two problems meet in the cosmology literature when anthropic considerations are used to predict cosmological parameters by conditionalizing the distribution of, e.g., the cosmological constant on the number of observers it allows for. However, uniform probability distributions usually appealed to in such arguments …

On Nonequilibrium Statistical Mechanics, Joshua M. Luczak

Electronic Thesis and Dissertation Repository

This thesis makes the issue of reconciling the existence of thermodynamically irreversible processes with underlying reversible dynamics clear, so as to help explain what philosophers mean when they say that an aim of nonequilibrium statistical mechanics is to underpin aspects of thermodynamics.

Many of the leading attempts to reconcile the existence of thermodynamically irreversible processes with underlying reversible dynamics proceed by way of discussions that attempt to underpin the following qualitative facts: (i) that isolated macroscopic systems that begin away from equilibrium spontaneously approach equilibrium, and (ii) that they remain in equilibrium for incredibly long periods of time. These attempts …

Philipp Frank: Philosophy Of Science, Pragmatism, And Social Engagement, Amy N. Wuest

Electronic Thesis and Dissertation Repository

Philipp Frank––physicist, philosopher, and early member of the Vienna Circle––is often neglected in retrospective accounts of twentieth century philosophy of science, despite renewed interest in the work of the Vienna Circle. In this thesis, I argue that this neglect is unwarranted. Appealing to a variety of philosophical and historical sources, I trace the development of Frank’s philosophical thought and, in so doing highlight the roles played by history, sociology, values, and pragmatism in his philosophy of science. Turning to contemporary literature, I then argue that Frank’s work should be understood as an early instance of what is now called “socially …

Some Disputed Aspects Of Inertia, With Particular Reference To The Equivalence Principle, Ryan S. Samaroo

Electronic Thesis and Dissertation Repository

This thesis is a contribution to the foundations of space-time theories. It examines the proper understanding of the Newtonian and 1905 inertial frame concepts and the critical analysis of these concepts that was motivated by the equivalence principle. This is the hypothesis that it is impossible to distinguish locally between a homogeneous gravitational field and a uniformly accelerated frame.

The three essays that comprise this thesis address, in one way or another, the criteria through which the inertial frame concepts are articulated. They address the place of these concepts in the conceptual framework of physics and their significance for our …

Structures In Real Theory Application: A Study In Feasible Epistemology, Robert H. C. Moir

Electronic Thesis and Dissertation Repository

This thesis considers the following problem: What methods should the epistemology of science use to gain insight into the structure and behaviour of scientific knowledge and method in actual scientific practice? After arguing that the elucidation of epistemological and methodological phenomena in science requires a method that is rooted in formal methods, I consider two alternative methods for epistemology of science. One approach is the classical approaches of the syntactic and semantic views of theories. I show that typical approaches of this sort are inadequate and inaccurate in their representation of scientific knowledge by showing how they fail to account …

Basic Cable: Notes Toward Digital Ontology, Robbie Cormier

Electronic Thesis and Dissertation Repository

This thesis begins the work of constructing a fundamental ontology that employs the network automaton—a class of abstract computer program—as its model. Following a brief historical overview of the theory of network automata and its culmination in the work of Steven Wolfram, I examine how it bears on the ancient question concerning whether the continuous or the discrete has ontological primacy, consider the ontological status of materiality in consultation with Deleuzean ontology, and introduce the concept of prescience as a means of topologically mapping emergent patterns within the causal relations that compose the network. Finally, I will break the …
