What makes a work of art 'good' by contemporary philosophy of art standards?
gpt
I’m an undergraduate taking an Aesthetics course. Gordon Graham provides three normative theories for evaluating art: expressivism, cognitivism, and hedonism. Graham is a cognitivist, meaning he thinks what the extent to which art helps us understand truths about the world and our place in it is the metric by which we (should) judge the value of art.
