It is not the theories that have significance, but the habits of thought. For the truly practical person it is not important what the contents of the thoughts are, but the activity they bring about. That is what it is all about. It does not matter whether someone is an idealist, but what is important in life is that one’s thoughts are fruitful, that they stimulate life and bring progress. It must be kept in mind that Spiritual Science does not want to have any part in one or the other dogma or belief system. It is of no importance that someone has many spiritual theories, but that these ideas are fruitful when applied to life. When someone declares that they are not materialistic and believe in the force of life, even in the spirit, but at the same time treat the human being like a gigantic test tube when considering nutritional matters, his worldview cannot bear fruit. Spiritual Science can only bring adequate answers to concrete questions when it is able to penetrate the details – and it is indeed able to shed light on nutritional as well as health issues.
