The dream of Socrates, that virtue be able to be taught, will come true; more and more it will be possible on earth not only for our intellect to be stimulated and energized by this teaching but, through this teaching, for moral impulses to be spread abroad.
Schopenhauer said, “To preach morality is easy; to establish it is most difficult.” Why is this? Because no morality has yet been spread by preaching. It is quite possible to recognize moral principles and yet not abide by them. For most people the Pauline saying holds good, that the spirit is willing but the flesh is weak. This will change, through the moral fire streaming from the figure of Christ. Through this, the need for moral impulses on earth will be increasingly clear to man.
Man will transform the earth in so far as he feels with ever-increasing strength that morality is an essential part of the earth. In the future, to be immoral will be possible only for people who receive immoral help, who are goaded in this direction, who are possessed by evil demons, by Ahrimanic, Asuric powers, and who strive for this possession.
This is the future condition of the earth: there will be a sufficient number of people who increasingly teach morality and at the same time offer a moral foundation, but there will also be those who by their own free decision surrender themselves to the evil powers and thus enable an excess of evil to be pitted against a good humanity. Nobody will be forced to do this; it will lie in the free will of each individual.
