4. The Rise of Spiritualism. The Need for the Science of the Spirit
In earlier ages man had other faculties. When we go back in historical evolution, we find that the further we go the more possible it was for man to look into the spiritual world. But the faculties he then had were not such that he could use them in freedom. They were more or less involuntary. The force enabling him to reach a certain knowledge came over man in earlier ages somewhat in the way in which the desire for sleep overtakes a man. It was, however, a force that entered the spiritual world. In order for man to take a step forward toward achieving the faculty of making free decisions and developing freedom, he had to be separated from the forces that, in earlier times, brought him nearer the spiritual world but also allowed him less freedom. Man had to pass through a period of development in which he was shut off as by a veil or sheath from the spiritual world so that he might become freer. To be sure, this development is still far from complete but a first stage reached its conclusion in the middle of the nineteenth century. Those who know something of the spiritual life behind the sensory life recognize that since that time it is a growing necessity for other forces to be added to those of observation and knowledge based on mere intellect. These other forces slumber in the human soul and must be developed, even as the forces have evolved that have brought humanity to achieve the great advances of the last three or four centuries.
