but everything those works actually do is offend.
being offended then is the impetus to further think about it; a line of thought, which is completely out of the hands of the artist.
Nonsense. When I look at "Fountain" I'm not offended at all, and I doubt that you are either. And I think that even people who
are offended by it have other reactions as well. To suggest that its sole purpose is merely to offend, and nothing else whatsoever, is to diminish it.
Also, it's striking that you've moved from this strong claim:
(1) The sole
purpose of these works is to offend.
- to this even stronger claim:
(2) The sole
effect of these works is to offend.
As I said, I don't think (1) is true at all, and I seriously doubt whether any work that satisfies (1) would count as art at all. But (2) is clearly false, to an absurd degree, in the case of the works cited, and I seriously doubt whether any work satisfies (2)
at all. Can there really be anything which
absolutely everyone without exception finds offensive, and to which
absolutely everyone without exception has no other reaction at all? Sounds pretty implausible to me - and if there is such a work, then it would certainly be breaking forum rules to post it here. Not that you'd want to, of course, because you'd find it offensive and without merit yourself.
