Lecture I

Now we are approaching the middle of human life, Jesus of Nazareth said, which is in the thirties, where the forces of youth cease to grow and begin to decline. We are now living in an age that corresponds to the twenty-eighth to the thirty-fifth year of the individual person, where his life begins to decline. Whereas in the case of some individuals other forces are present, in humanity in general they are no longer there. That is the great suffering, that humanity should become aged, having its youth behind it, being in the epoch corresponding to the twenty-eighth to thirty-fifth year. Where should new forces come from? The forces of youth are exhausted.
