Rudolf Steiner (b. Rudolf Joseph Lorenz Steiner, 1861-1925) was born in the small village of Kraljevec, Austro-Hungarian Empire (now in Croatia), where he grew up. As a young man, he lived in Weimar and Berlin, where he became a well-published scientific, literary, and philosophical scholar, known especially for his work with Goethe's scientific writings. Steiner termed his spiritual philosophy anthroposophy, meaning ""wisdom of the human being."" As an exceptionally developed seer, he based his work on direct knowledge and perception of spiritual dimensions. He initiated a modern, universal ""spiritual science"" that is accessible to anyone willing to exercise clear and unbiased thinking. From his spiritual investigations, Steiner provided suggestions for the renewal of numerous activities, including education (general and for special needs), agriculture, medicine, economics, architecture, science, philosophy, Christianity, and the arts. There are currently thousands of schools, clinics, farms, and initiatives in other fields that involve practical work based on the principles Steiner developed. His many published works feature his research into the spiritual nature of human beings, the evolution of the world and humanity, and methods for personal development. He wrote some thirty books and delivered more than six thousand lectures throughout much of Europe. In 1924, Steiner founded the General Anthroposophical Society, which today has branches around the world. Robert McDermott, Ph.D., is president emeritus and chair of the Philosophy, Cosmology, and Consciousness Program at the California Institute of Integral Studies (CIIS). His publications include Radhakrishnan (1970); The Essential Aurobindo (1974, 1987); The Essential Steiner (1984); (with Rudolf Steiner) The Bhagavad Gita and the West (2009); and The New Essential Steiner (2009). He has also published on William James, Josiah Royce, M. K. Gandhi, the evolution of consciousness, and American thought. His administrative service includes president of the New York Center for Anthroposophy; president of the Rudolf Steiner [summer] Institute; chair of the board of Sunbridge College (New York) and of Rudolf Steiner College (California). He was a member of the council of the Anthroposophical Society in America (1996-2004). He is the founding chair of the board of the Sophia Project, an anthroposophic home in Oakland, California, for mothers and children at risk of homelessness. He is a Lindisfarne fellow, a Fetzer mentor, and a member of the Esalen Corportion. Thérèse Trédoulat is a gardening author based in France. She updates the annual Moon Gardener's Almanac, continuing the work of Céleste, a French lunar gardening specialist who died a few years ago. George Adams (1894-1963) was a close student of Rudolf Steiner, and translated many of his lectures given to English-speaking audiences. Beginning in 1935, Olive Whicher worked with George Adams in their research into mathematics and physics until his death in 1963. He translated and published numerous books, lectures, and articles. Eknath Easwaran (1910-1999) was an Indian-born spiritual teacher, author, and translator and interpreter of Indian religious texts, including the Bhagavad Gita and the Upanishads. He was a professor of English literature at the University of Nagpur in India, and in 1959 moved to the United States as a Fulbright Scholar at the University of California, Berkeley, where he taught courses on meditation. In 1961, Easwaran founded the Blue Mountain Center of Meditation and Nilgiri Press, based in Northern California, which published more than thirty of his books. Easwaran was influenced by Mahatma Gandhi, whom he met when he was a young man. He developed a method of meditation (silent repetition in the mind of memorized inspirational passages from the world's major religious and spiritual traditions), which later came to be known as Passage Meditation.
The presentation is overall quite clear, and the style is often captivating. Many figures, examples and exercises complete the monograph. Finally, it is worth adding a mention on the bibiography, which is at present a truly complete account of papers in this area. Mathematical Reviews
