The “Knife and Fork Factory” anectdote makes me think of abstract art.
It seems to me that small children are quite happy with the idea of abstract art; paintings don’t have to represent anything, they are just made for the joy of creation, and displayed for the joy of looking. As we get older (and more able to create representative images), I think we sometimes lose this facility. Some people regain the ability to relate to abstract work, others never quite do. I’m trying to. Some abstract art moves me (the red Rothkos in the Tate; Barbara Hepworth’s organic forms). Some I struggle with (Pollock). I have only recently started to paint abstracts, though, and then very rarely.
