Introductory Lecture

What does it really amount to when a man has a general, theoretical belief in a spiritual world? To believe in theory in a spiritual world means to receive it into one's thoughts. But although in their own original nature thoughts represent the most spiritual element in modern man, the thoughts themselves are such that in their development as inner spirit during the last four to five centuries, they are adapted only to receive truths relating to material existence. And so people to-day have a spiritual life in thoughts, but as members of contemporary civilisation they fill it with a material content only. Theoretical knowledge of Anthroposophy also remains a material content until there is added to it the inner, conscious power of conviction that the spiritual is concrete reality; that wherever matter exists for the outer eyes of men, not only does spirit permeate this matter, but everything material finally vanishes before man's true perception, when this is able to penetrate through the material to the spiritual.
