Art lives upon discussion, upon experiment, upon curiosity, upon variety of attempt, upon the exchange of views and the comparison of standpoints; and there is presumption that those times when no one has anything particular to say about,and has no reason to give for practice or preference, though they may be times of honour, are not times of development – are times, possibly even, a little of dullness. the successful application of any art is delightful spectacle, but the theory too is interesting; and though there is a great deal of the later without the former i suspect there has never been a genuine success that has not had a latent core of conviction. Discussion, suggestion, formulation, these are things are fertilizing when they are frank and sincere.
Henry James, “The Art of Fiction” Major Stories and Essays (New York: Literary Classics of the United States, 1999) 572-573
Art has a foundation of many different aspects, however thy are what make the idea of art a hard concept to understand.
