Occult science desires to free the natural-scientific method and its principle of research from their special application that limits them, in their own sphere, to the relationship and process of sensory facts, but, at the same time, it wants to retain their way of thinking and other characteristics. It desires to speak about the non-sensory in the same way natural science speaks about the sensory.
While natural science remains within the sense world with this method of research and way of thinking, occult science wishes to consider the employment of mental activity upon nature as a kind of self-education of the soul and to apply what it has thus acquired to the realms of the non-sensory. Its method does not speak about the sense phenomena as such, but speaks about the non-sensory world-content in the way the scientist talks about the content of the sensory world. It retains the mental attitude of the natural-scientific method; that is to say, it holds fast to just the thing that makes natural research a science. For that reason it may call itself a science.
