the Anthroposophical Movement (GA 237), lecture of 3 August 1924. Tr. G. Adams, D. Osmond. London: Rudolf Steiner Press 1977. We are now in the 5th epoch; the 6th epoch will see a completely different race, noble and beautiful compared to the split-off decadent race of revoltingly ugly, bestial, sensual people who have many vices, arousing much greater revulsion than is possible with present-day humanity, because there will have been downward development. And you can see it clearly stated in the Book of Revelation, in what is called The Last Judgement. Anyone who is completely selfless may be ripe now for the 6th epoch. He may still incarnate a number of times, but only in order to help others. Some may find that the Last Judgement sounds harsh, but they do, after all, have the choice. Please do not misunderstand me. I mean not concerning reincarnation but concerning the 6th epoch.
Why do old people grow weak-minded, seeing that the soul remains unchanged?
The soul does not change. It never descends from the level it has reached, but its instrument has grown weak. It is like a great pianist who cannot play as well as before if the instrument is poor.
You will say the soul no longer knows its own level. Yes, for it cannot see itself for as long as it is in a physical body. There you altogether have only the reflection of the soul, the mirror reflection. When the mirror grows dim or breaks, it can no longer give a reflection. It is only the occult student who is truly able to perceive his soul.
