V. Can a method of gaining insight into spheres beyond the sense-perceptible world be given a scientific basis?

We are considering the objections that are meant to defeat spiritual science as a supersensible science. When the spiritual investigator himself uses the observation of soul which is necessary in order to become aware of all the things which have been said today, when he enters into the human inner life with this self observation he will find the following. Firstly, because thinking tends to cast the human being into the abyss of non-existence—initially non-existence in relation to the outside world perceived with the senses—and because human beings have a certain horror, if I may use the term, of thus entering into thinking, in so far as this thinking gains its true form when truly entered into, people have no desire to enter truly into the nature of reflective thinking with the aid of spiritual science. They shy away from thus entering into the nature of reflective thinking. They fail to realize, however, why they shy away from it. They do so from a subconscious feeling that is no less active and which one is unable to control exactly because it is subconscious. It is a certain feeling of fear, a subconscious fear of starting from such non-existence. At its opposite pole this subconscious fear generates lack of interest in natural phenomena in its spiritual depths. People do not want to look at natural phenomena in all the places where they evidently cannot be explained out of themselves. One has to go further and find their complement in quite a different direction. Lack of interest, stopping where one should really go deeper—that is the opposite pole of the fear. Again it is a subconscious lack of interest. This, ladies and gentlemen, is the one side of it.
