So even the most reclusive artist is in a dialogue: with all the artists of the past several millenia ;)
And then there's another deep discussion about what is actually art. I would argue if an artist is motivated by social factors to make art, they are not really making art.
Like most chefs are paid to cook but are they doing it, fundamentally, to get paid or there's really another fundamental reason driving their passion?
If someone is painting or making music for social reasons like being accepted by others, becoming famous, finding their identity in what others think of their painting/music, getting rich, etc, that's not really what art is about.
Of course this is only my opinion about a modern conception of art and what an artist is.
Theres an entire subset of socializing/communal happenings as art called relational aesthetics tho
It's not a dialogue if they're dead.
