V. Whitsun: The Festival of United Soul-Endeavour

In many animal species the group-ego is a wise being. If we think of how certain kinds of birds live in the north in the summer and in the south in the winter, how in spring they fly back to the north—in this migrating flight of the birds there are wise powers at work; they are in the group-egos of the birds. Anywhere you like in the animal kingdom you can find the wisdom of the group-egos in this way. If we turn back to our schooldays we can remember learning how modern times gradually arose out of the Middle Ages, of how America was discovered, and how gunpowder and printing were invented, and later still the art of making paper from rags. We have long been accustomed to such paper, but the wasp group-soul invented it thousands of years ago. The material of which the wasp's nest consists is exactly the same as is used in making paper out of rags. Only gradually will it become known how the one or the other achievement of the human spirit is connected with what the group-souls have introduced into the world.
