Ancient Greek philosophy, ancient Greek natural philosophy and science, Aristotelian ethics, ethics and global poverty. I have written on the intersections between ancient Greek natural philosophy and natural sciences, including mechanics, medicine, optics, physics and theory of mixture. Although I have written on topics ranging over the entire period of Greek antiquity, many individual research papers concern the role of Hellenistic science on natural philosophy, especially that of the Aristotelian school. This culminated in a 2009 monograph on the impact of ancient Greek mechanics on ideas about causation and explanation of the natural world.
More recently, I have been writing on the metaethical foundations of Aristotle’s ethics, especially the role of naturalism in his thought, and the recent situationist critique of virtue ethics. My 2019 book on Aristotle’s ethics defends the notion that Aristotle was self-aware of second-order questions about the source of and justification for ethical demands, but denies that he thought the appeal to human nature could settle these questions.
In addition, I have interests in questions of ethics and global poverty.
