  Thomson also argues that we can relativize our notion of goodness to a class of things. One can be a good piano player for a six-year old without being a good piano-player, full stop. And this class-relativization can occur whether we are talking about good instances of kinds or good-modified things. Thus, we can have a good typewriter (for a typewriter built in 1900), or an individual who is good at crossword puzzles (for an athlete).
