Thanks, BC & Deb, for your reactions to the Winslow Homer quote. If you haven't checked back in the comment section, please do because I entered a response there.
Moving on, here's another quotation for your consideration. As you might imagine, this one sits better with me. But again, I'd be interested in your reaction.
"The position of the artist is humble. He is essentially a channel." - Piet Mondrian
