What is it for something to be good? Using the example
of an Ebola-like microbe, I argue that a merely kind-based account of goodness
is defective (Chapter 1). I offer instead an account that is both kind-based
and platonic (Chapter 2). On such an account, goodness turns out to be
non-natural (Chapter 3). However, non-naturalists can explain why the goodness
of an individual supervenes on its natural properties, by appealing to the
essence of the kind to which it belongs (Chapter 4).
