Scientific cognitivists argue formalist aesthetics of nature are (i) inadequate for appreciating the full range of nature’s aesthetic values and (ii) too subjective to be useful for defending nature conservation. I argue that (i) is false because moderate formalists can appreciate nature for its performances, not merely objects and vistas. I argue (ii) is false because moderate formalists can argue that appreciation of beauty (including natural beauty) is a constitutive good of human flourishing, whose realization relies on access to a (...) rich and diverse array of aesthetically rewarding experiences throughout a lifetime. On these grounds, moderate formalists (among others) can justify conserving distinctive natural entities and environs for our own and future generations’ good. (shrink)
