 It is, of course, open to a critic to argue there is little reason to think that only states of mind have value. Ross does little to defend the view. Indeed, he might be forced to reconsider whether only states of consciousness possess value once he is confronted with the idea that achievement is among the things we seem to value, where this involves ‘having a goal for how the world should be and then realizing it’ (Hurka 2014, 209). Achievement involves interacting with and affecting the world, including doing things like writing a book, raising a child to adulthood and building a muscular physique.
