I’ve been reflecting on an area I think I should have given some attention to in the original document. Here’s a possible 23rd ( I think it would go in after current 11):
We should be wary of attempts to set up a canon, especially one which privileges particular national or ethnic traditions. We should fear snobbery but also be aware of the pressures of commerce. In any event we should not abandon the idea that particular works, from whatever tradition(s), might do whatever-artworks-do in some way more effectively than others. We need to look, feel and think hard; be at the same time generous, open minded and intensely suspicious.
That’s a draft. I’m going to think about it some more… comments welcome…mail me at email@example.com
