Perhaps it is the case that if, as brianvds suggests, “we could precisely codify what exactly that ‘something’ is” then anything based on such a codification ceases to be art for want of originality (or an essential element thereof).
However, it’s not obvious to me that, provided such a codification is sufficiently abstract, it would somehow forestall originality. An accomplished artist who works in a particular medium with a preferred style (e.g., a painter who only does pointillisms on hardboard) can of course only render works that are physically possible with that combination of medium and style, but that does not mean the art so produced lacks originality because the content of the work counts at least as much as its presentation.
And so, with regards to my earlier post about English Creative Writing, it is similarly a bit of stretch to suggest that because an author works in a particular genre with a style that is their own but still recognisably derivative of other authors, such an author lacks originality because plot, structure, character development, etc. are also critical ingredients (Stephen King and John Grisham are good examples).
The “type of composition and a writing style” I wrote about isn’t a rigid algorithmic or automated procedure where you churn out virtual clones under different titles. Rather, it’s a somewhat fuzzy and loose collection of flexible guidelines and preferred ways of structuring a story, of phrasing things, of characterisation, of plot elements, and so on — and also what to avoid concerning those aspects. I think the school’s aim was to inculcate the ability to recognise what is generally thought of as good writing, and to get pupils to emulate it. It’s not an easy thing to convey those aspects of writing, and I suspect the teaching thereof is even more difficult, hence the focus on classic literature where the pupil is exposed to them and will hopefully try to imitate them, eventually to refine the overall flavour of their writing to their own unique blend.
Finally, we must not lose sight of the fact that, lacking precise evaluation criteria, a work of “art” can only become a classic through sufficient consensus of various individuals and parties. As individuals, we may or may not like a specific painting or sculpture or composition, but our opinion in any particular case has only limited relevance concerning whether the work in question is true art or not. For example, I have a pervasive and especial, even morbid, dislike of collages but I wouldn’t presume to suggest that they aren’t art.
