It was the maxim, I think, of Alphonsus of Aragon, that dead counsellors are safest. The grave puts an end to flattery and artifice, and the information we receive from books is pure from interest, fear, and ambition. Dead counsellors are likewise most instructive, because they are heard with patience and with reverence.
I do remember at my very first opening in 1979 another artist coming up to me, and he was haranguing me, saying, "Did you really intend for these things to be so dumb? You just put it there and took a picture of it. " He wouldn't let it go. So that's what made me think about the dumbness aspect more.
