I started philosophy being interested in metaphysics and pursued my graduate studies with questions of ontology primarily in mind. When it came to writing a dissertation, focus was required, and I decided to use the ontological status of moral properties as a case study in metaphysics. Acknowledging that studying metaethics (the metaphysics of ethics) demands far more than just a little familiarity with moral philosophy, I did my best to become an expert. After studying moral philosophy for a while, it became clear that working on moral problems has a value in its own right, independent of its value for learning metaphysics; this change in attitude accelerated as I became more familiar with the moral philosophy of the Ancient Greeks. Thus, I have learned to see the progression of my own academic interests as a mini-lesson in developmental practical rationality: I began studying ethics for purely instrumental reasons, but I then learned of its intrinsic value and now happily pursue it for its own sake.
