Sometimes, when I go to dinner parties organized by my partner, people ask me what I do, and I say that I'm a philosopher. But when I fumble at their questions about ‘my philosophy’, my partner will describe what I do by saying, ‘He uses big words to explain little words.’ Although this is meant tongue in cheek, it's basically right. My philosophical research is mainly in metaethics and the philosophy of language with a focus on the semantics of moral words. This means, for better or worse, that I use big words to explain little words.
