The Supernatural Man and the Questions of Free Will and Immortality Based on the Results of Spiritual Science

What I have just explained is first considered from a spiritual and psychological point of view. But the time will come when, because the foundations already exist in today's natural science, anyone who really studies physiology, biology and anatomy will come to the conclusion that, precisely when one is able to properly survey the physiological and biological facts of the human being, then a full confirmation of what I have discussed can also be found from a natural scientific point of view. In this regard, one must simply say: the scientific approach of the nineteenth century and up to now, however meritorious it is, has oversimplified things, and above all has oversimplified the development of the human being. Yes, when one carries out something like what I am about to briefly mention, then one really feels how spiritual science can only come into its own when it is possible for it to work in a laboratory-like, clinical way, just as ordinary official science works today.
