The mysterious Metaphysical Elders (not to be confused with these guys) also discuss the perennial favorite: why aren’t their more Mormon geniuses, if the gift of the Holy Ghost is really on us? See here, and here, and here.
They cite this essay. Good essay. It is, how shall I say, a good essay.
I have much to say on this topic, and there is much more than I can say, but I am pressed for time (And therein lies part of the tale). So I will favor us with a single observation:
I think Mormons for too long have had a narrow conception of Art. We live in times that themselves have a very narrow view (Art is about challenging authority and asking questions) and we have adopted a view in response: Art is about affirming our authoritative beliefs and answering the questions.
I think its truer (although Heaven knows my understanding of aesthetics is still threadbare) to say that Art functions much like the Spirit does in D&C 50:21-25 : whereas ordinary communication can normally only give a remote and outlined access to experience, truth, and beauty, the Spirit adds the thing itself to the conversation. Art, to a lesser degree, does the same.
