So I am totally aware that when I defend the autonomy of art I'm going counter to my own development. It's more an instinctive reaction, meant to protect the private aspect of the work, the part I am most interested in and which nowadays is at risk in our culture.
Grown people know that they do not always know the why of things, and even if they think they know, they do not know where and how they got the proof. Hence the irritation they show when children keep on demanding to know if a thing is so and how the grown folks got the proof of it. It is so troublesome because it is disturbing to the pigeonhole way of life.
