If you using local color in an unobtrusive way, it is all for the good. But if you stress it, the whole thing is artificial. But it should be used, I mean, it's not forbidden. But you don't have to stress it.
Jorge Luis BorgesA writer, or any man, must believe that whatever happens to him is an instrument; everything has been given for an end. This is even stronger in the case of the artist. Everything that happens, including humiliations, embarrassments, misfortunes, all has been given like clay, like material for one's art. One must accept it.
Jorge Luis BorgesI know of a wild region whose librarians repudiate the vain superstitious custom of seeking any sense in books and compare it to looking for meaning in dreams or in the chaotic lines of one's hands . . . They admit that the inventors of writing imitated the twenty-five natural symbols, but they maintain that this application is accidental and that books in themselves mean nothing. This opinion - we shall see - is not altogether false.
