I work on ethics, moral psychology, and nineteenth-century philosophy. This interview from 2018 is a good introduction to my work and philosophical interests.
You can find all of my papers and books on this page. Some of the main topics I've addressed are:
Fanaticism, extremism, and the moral psychology of devotion: recently, I've been working on a book called Devotion: Nihilism, Fanaticism, and the Longing for Invulnerable Ideals. The book examines the way in which human beings are driven by a need to express devotion. I discuss the way in which this need intersects with perceptions of one's life as meaningful; how it is manifest in group psychology; and the way in which it can go astray in nihilism, fanaticism, and various forms of extremism.
I've also done a lot of work on Nietzsche's ethics and philosophical psychology: if you want an introduction to my work on Nietzschean flourishing and my approach to moral psychology, you could check out this paper on self-conscious agency and this paper on Nietzsche's ethics.
In general, most of my work has focused on topics at the interface of ethics and philosophy of mind, including the way in which normative claims might be justified; the nature of self-consciousness; the nature of agency; the notion of drive; and the concepts of free agency and unified agency. I address these topics in part by mining the work of certain eighteenth- and nineteenth-century philosophers. I draw especially on the work of Kant, Hegel, Schopenhauer, and Nietzsche, arguing that by appropriating and developing aspects of their accounts, we can gain insight into the above topics. As these remarks may indicate, I treat the history of philosophy not merely as a subject of antiquarian interest, but as a wellspring of ideas containing the resources to shape debates currently at the forefront of our field.
