XI. Progressive Development Through The Different Cycles Of Culture

The minerals outside are the counterpart of the bones. The Earth perpetuated this epoch in the masses of rock and man in his skeleton. Man then gradually became an upright walking being, thus changing over from his former horizontal position into a vertical one. He turned round, so that his front extremities became organs of work, and his other extremities were used for walking. There is a connection in all this, for no being without a sound-producing larynx and an upright walk can be an Ego-being.
