Most of Steiner's comments and suggestions for Waldorf education at the beginning of the 1920s, almost 90 years ago, are accessible free online here for anyone interested to read.
This is also the case with much of what he wrote and said at different times through his life, 90-110 years ago, in terms of articles, books, and lectures on more esoteric subjects (in total encompassing some 90,000 pages), a large part of it accessible here, here and here to drop their jaws at, or repeatedly hit themselves on the forehead at when reading.
What probably stands out as a mystery to most is how everything he tried to penetrate from a spiritual perspective in terms of trying to understand the origin of us as humans, of the world, and of cosmos, can lead to - among other things - an educational practice, that 85 years after Steiner's death makes someone like Kenneth Chenault, former Waldorf student (Waldorf School of Garden City) and today Chairman and CEO of American Express write:
"My parents were looking for a school that would nurture the whole person. They also felt that the Waldorf school would be a far more open environment for African Americans, and that was focused on educating students with values, as well as the academic tools necessary to be constructive and contributing human beings. ... I think the end result of Waldorf education is to raise our consciousness.
"There is a heightened consciousness of what our senses bring us from the world around us, about our feelings, about the way we relate to other people. It taught me how to think for myself, to be responsible for my decisions.
"Second, it made me a good listener, sensitive to the needs of others.
"And third, it helped establish meaningful beliefs. In all the Main Block lessons in history, science, philosophy we really probed the importance of values and beliefs. In dealing with a lot of complex issues and a lot of stress, if that isn't balanced by a core of meaningful beliefs, you really will just be consumed and fail."
I very much doubt that the Chairman and CEO of American Express considers himself to be an "indoctrinated" closet anthroposophist, or what he would consider to be an anthroposophist in any sense, after having gone through a Waldorf education.
Or maybe he just has not told anyone?
Well, just some reflexions from ..., sorry, by a bar stool.
