Zachary William Lee Goodsell

I'm a philosophy graduate student at the University of Southern California. I started in Fall 2018. Before that, I completed a Bachelor of Science in mathematics at the University of Queensland (2014-2016) and a Bachelor of Arts (Honours) in philosophy at the University of Sydney (2017).

My research interests include (in no particular order) logic, metaphysics, epistemology and the philosophy of probability, the philosophy of mathematics, decision theory, and the philosophy of language.

Publications

Forthcoming

“Arithmetic is Determinate”. Forthcoming in the Journal of Philosophical Logic Arithmetical truths are shown to be determinately true in a minimal plural modal logic for determinacy.

“A St Petersburg Paradox for Risky Welfare Aggregation”. Forthcoming in Analysis. The principle of Anteriority says that prospects are equally good if they are equally good for every possible person. I show that Anteriority is inconsistent with some very plausible principles of axiology and decision theory.

2020

“What is an Extended Simple Region?” (with Michael Duncan and Kristie Miller). In Philosophy and Phenomenological Research 101 (3): 649-659. 2020. We propose a novel view about what could make a spatial region extended (that is, bigger than a point), and investigate some consequences of this view.

Works in Progress

(Drafts available. Send me an email.)

Philosophy of Logic and Mathematics

Me and Juhani Yli-Vakkuri are coauthoring a book on higher-order logic and its applications to metaphysics and the foundations of mathematics. We hope to have something shareable by the end of the year.

Metaphysics

[Name blinded for review.] I argue that Morgenbesser was mistaken about the coin.

Epistemology and Philosophy of Probability

[Name blinded for review.] I argue that truths are more likely than contradictions, and respond to various objections in the literature.

[Name blinded for review.] Mr Magoo doesn't have to look at a tree to know that it is not exactly 10 metres tall. This makes trouble for the view that a conviction that could have easily been had in error cannot be knowledge.

Axiology and Decision Theory

[Name blinded for review.] A general axiomatic framework for decision theory in the presence of unbounded value is developed by investigating various consequences and consistency results.
