Spiritual Ground of Education, by Rudolf SteinerSteiner Books
The Manchester Guardian reported at the time: "Steiner’s lectures... brought to us, in a very vivid way, an ideal of humanity in education. He spoke to us about teachers who, freely and unitedly, unrestricted by external prescription, develop their educational methods exclusively out of a thorough knowledge of human nature. He spoke to us about a kind of knowledge needed by the teacher, a knowledge of the being of man and the world, which is at the same time scientific and also penetrates into the most intimate inner life, which is intuitive and artistic."
Long out of print, these lectures are among the best and most accessible introductions to Waldorf education and what it means for modern culture.
