18. What is Revealed When One Looks Back into Former Lives Between Death and a New Birth II

By this means human Thinking was evolved. In the life between death and a new birth man gradually developed that faculty which in primeval times had formed the thoughts in him. It was a faculty which at that time could behold the Spiritual, though it was like what is now mere sense perception. For at that time the Physical still carried the Spiritual upon its surface. Today, however, the faculty of thought preserved from that time can only work as restricted sense-perception. Man's power to lift himself in thought to the spiritual world gradually declined. This became fully evident at length when in the age of the Spiritual Soul the spiritual world was veiled for man in complete darkness. Thus in the nineteenth century it came about that the best men of science, unable to become materialists, declared: We have no alternative but to limit our research to that world which can be investigated by measure, number and weight and by the senses. We have, however, no right to deny a spiritual world, hidden beneath this world of Nature. In such words they indicated that there might be a world full of light, unknown to man, where man can only stare into an empty darkness.
