Triangle, Circle and Soul, by Harry KretzRudolf Steiner College Press
A thoughtful exploration of form by an experienced Waldorf math teacher.Moses wrote that God created man, a living soul. Plato wrote that God geometrizes. If the soul is thought of as the threefold principle of life-thinking, feeling, and action-and the triangle is a form with three sides, is there a connection? The author's dream experience seems to say yes.
Harry Kretz taught high school math for many years at Hawthorn Valley Waldorf School in New York. Since retiring from full-time work, he has worked more than full time traveling to teach courses for a few weeks at a time in various Waldorf schools and in teacher training centers.
