Time: The Forgotten Dimension of Art
Reply to Derek Allan
Hi, Derek

Yes, thank you: I think I get what you have in mind to do, now.

You accept that (some) art remains significant over time but do not want to make this feature of (some) art a criterion for the quality of art. You want to enquire into how and why art keeps its resonance over time. It seems to me like yours are genuine and interesting questions. Interesting project! I will definitely keep an eye on how it unfolds.

Thank you

Filippo
