Rudolf Steiner: "Spiritual strength has been cultivated within the ruling classes in a way that has unsocially restricted its achievements to these classes. What was accomplished within these classes could only be transmitted artificially to proletarian humanity. And this part of humanity could draw no soul-sustaining strength from spiritual life because it did not really participate in these spiritual values. Institutes of ‘popular adult education’, ‘leading’ the people to an appreciation of art, and similar actions, are not really valid means to the propagation of spiritual values in the people as long as these spiritual values retain the character they have taken on in recent times. The ‘people's’ innermost human essence is not to be found in such values. They can therefore only look on from an outside observation point."
