My Current Projects…

Moral Paradox and Metaethics: An engagement with paradox has been at the heart of analytical moral philosophy from the 1970’s to present. I argue that this of metaethical significance. Unless we can resolve the paradoxes, scepticism and nihilism loom. I’m writing a book about this. Recent papers on this project:

• A New Case for Moral Skepticism: The Argument from Paradox. Forthcoming at Journal of Philosophy.

• Why Moral Paradoxes Support Error Theory. Journal of Philosophy (2023).

• A New Argument for Error Theory. Nous (2022).

Epistemology in the Search for Extraterrestrial Life: Scientists are optimistic that we will soon discover alien life. But what would it actually take? I’m writing a comprehensive epistemology for answering this. Some recent papers:

• Methodological Conservatism in the Assessment of Unidentified Anomalous Phenomena. Forthcoming at Ergo.
• Optimism in the Search for Extraterrestrial Life: A Philosophical Perspective. Proceedings of the Aristotelian Society (2025).

• New Work on Biosignatures. Mind (2023).
• Arguing about Extraterrestrial Intelligence. Philosophical Quarterly (2023).
