My Current Projects…
I’m working on two projects. One is about the implications of the axiological paradoxes of the past half century. The other is about the search for extraterrestrial life. I have recently finished a book manuscript about this: Will We Find Life Beyond Earth? A Philosophy of the Search for Extraterrestrial Life. If you’d like to see it, get in touch. Further information and links to papers below.
Moral Paradox and Metaethics: An engagement with paradox has been at the heart of 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. Recent papers on this project:
