In the sixth epoch (3573-5733) of post-Atlantean evolution, men will be born with bodies quite definitely expressing their inner, moral qualities. A man’s moral qualities will be recognised from his actual appearance. The moral physiognomy will then be very strongly in evidence and the physiognomy as it now is, will have receded more into the background. Man’s physiognomy today is largely determined through heredity: he resembles his parents, his grandparents, his people, and so forth. In the sixth epoch this will play no part at all; man will himself determine his outer appearance — as the result of his incarnations. Human beings will all be very different, but each will have a very definite stamp. It will then be known with certainty: You have before you now a well-disposed or an ill-disposed man. Just as it is known today: You now have before you an Italian or a Frenchman, it will then be known: Here is a malicious or a kindly man — with all the many gradations. More and more, therefore, the moral qualities will be expressed in the countenance.
