Does Art have to be didactic to be art?

answers1: art only has to create an emotional response in the viewer
to be art. It need not have any meaning.
answers2: It is not enough to say that art is only about emotional
response. We also have to factor in the, "who," of the response. For
any given audience, you may have different feelings or maybe no
feelings at all. A more complete answer addresses the collective or
universal response. What does the art contribute to humanity's
collective consciousness, its collective dream, and its universal
vision. The greatest works are always defined in context to the
whole, both didactically and emotionally. This legacy brings us the
meaning.
