That's how fine art works, you base proof upon proof.
The meaning of any situation is found in the frame within which we view the picture.
It is a nice naive concept which perhaps can be made into a rigorous theory. Art being only our ignorance of real causes, whether mermaids exist or not, art rules such as ideal body proportion would remain arbitrary. Open science widens the net.
A comprehensible proof is not necessarily the shortest one, but a proof of small width.
What art has in common with logic and mathematics is that art is a tautology. The art idea and artwork are the same. Both can be appreciated as themselves without going outside the context of the gallery or the museum for verification.
"Increments are the forms I understand, and repeating and expanding them to create systems and structures are acts of ritual."
