The History of Mankind in the Light of Supersensible Reality Research

Then comes the second age, which can be compared with the age of man up to the age of forty, but this is already the age which has already adopted a definite culture and of which we know that the people of that time were already dependent on many conditions of life, which penetrate into their lives as ideas. And here we come to the human age, which begins with the seventh to eighth century BC; people experience the forces of the body until the age of forty, which now already allows our individuality to decline from the age of 35 onwards. If this [Greco-Roman] period is not only considered from an external point of view, but is studied in depth, we find that it is based on the fact that man experiences life with his consciousness, whether this occurs in the course of history or in the life of an individual, up to the age of forty, when external circumstances influence the spiritual life. Today, we no longer achieve this; we only experience fully up to the age of 27 or 28.
