Jesaiah Ben-Aharon is a co-founder of the anthroposophical kibbutz Harduf, in which diverse initiatives are linked together in new social and economic forms. In 1986 he was invited to teach Rudolf Steiner's educational ideas in a teacher training college in Tel-Aviv. Through attempting to utilize and unite the spiritual paths in his research, Jesaiah Ben-Aharon was led to concentrate on the beginning of the second third of this century, especially the 12 years 1933-45. This period can be said to encompass the Spiritual Event of the Twentieth Century. Through c comprehending this event, we may gain the courage needed to renew and enliven anthroposophy as "the universal human language of our age."
