‘If Anthroposophy were to adopt a fanatic attitude, if Anthroposophy were ascetic, it would thunder against the modern civilization based on electricity. Of course, this would be nonsense, for only world-conceptions that do not reckon with reality can speak in that way. They may say: “Oh, this is ahrimanic! Let us avoid it!” — But this can only be done in an abstract way. For the very people who thunder against Ahriman, and tell us to beware of him, go downstairs after their sectarian meeting and enter an electric tramcar! So that all their thundering against Ahriman, no matter how holy it may sound, is (excuse the trivial expression) simply rubbish. We cannot shut our eyes to the fact that we must live with Ahriman. But we must live with him in the right way, that is to say, we must not allow him to have the upper hand.’
From Steiner, R. Concerning Electricity.
