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 …
