There are two barriers that often prevent communication between the young and their elders. The first is middle-aged forgetfulness of the fact that they themselves are no longer young. The second is youthful ignorance of the fact that the middle aged are still alive.
The mind, in proportion as it is cut off from free communication with nature, with revelation, with God, with itself, loses its life, just as the body droops when debarred from the air and the cheering light from heaven.
