Optimality And Teleology In Aristotle's Natural Science, Devin Henry

Devin Henry

In this paper I examine the role of optimality reasoning in Aristotle’s natural science. By “optimality reasoning” I mean reasoning that appeals to some conception of “what is best” in order to explain why things are the way they are. We are first introduced to this pattern of reasoning in the famous passage at Phaedo 97b8-98a2, where (Plato’s) Socrates invokes “what is best” as a cause (aitia) of things in nature. This passage can be seen as the intellectual ancestor of Aristotle’s own principle, expressed by the famous dictum “nature does nothing in vain but always what is best for …

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 …

On The Physical Explanation For Quantum Computational Speedup, Michael Cuffaro

Electronic Thesis and Dissertation Repository

The aim of this dissertation is to clarify the debate over the explanation of quantum speedup and to submit, for the reader’s consideration, a tentative resolution to it. In particular, I argue that the physical explanation for quantum speedup is precisely the fact that the phenomenon of quantum entanglement enables a quantum computer to fully exploit the representational capacity of Hilbert space. This is impossible for classical systems, joint states of which must always be representable as product states. I begin the dissertation by considering, in Chapter 2, the most popular of the candidate physical explanations for quantum speedup: the …
