It would be well, if especially from our Anthroposophical standpoint, as I have often told you, if it were recognised consciously and thoroughly, that even what is said now, even what we acquire as ever such advanced knowledge about Spiritual things, that must not be grasped as a sum of absolute dogmas. We must be quite clear that those who come after us, in future times, will see greater than we ourselves can.
On this rests the true Spiritual evolution of mankind, and everything of a hindering nature In the Spiritual progress of mankind rests finally on the fact that human beings will not admit this. They like to have truths presented to them, not as the truths for one definite epoch of time, but as absolute timeless dogmas.
