It is a wonder how much a person can learn from Youtube. So many questions are answered on the net. But there is something to be said for direct transmission. It was the way the old Zen masters did it, and the high craftspeople in Japan.
I was updating my web site, looking at my bio, remembering my education. I studied in art classes at three different universities on the graduate and undergraduate levels. This was not a place for direct transmission.
The Art Student’s League of New York allowed students to choose their own teachers. If you went for a five day a week class the teacher came in Tuesdays and Thursdays and spoke, shouted, or said nothing at all. It was closer to a master student arrangement. And days the teacher was not there we had other students, some having studied for years under the same teacher. It was, and I expect still is a true studio school.
