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

In the spiritual investigation with anthroposophical orientation of which we are speaking, we therefore look for the way that shows itself when we have lived through everything we are able to gain for the soul’s constitution from these two experiences. These spur us on, and when they enter into the soul they urge it to observe. Initially the discovery made in the direction of insight into the natural world makes us ask ourselves: What is the situation in our dealings with nature? What is the essential nature of our insight into nature? Anyone who gains a clear, unbiased picture of this insight into nature will find that it arises when in our thinking we perceive what our senses are sending out in a living way towards existing nature. Wanting to gain insight we do not simply take existing nature as it is but penetrate it with our thoughts. We have a feeling of immediate justification in thus summing up our insights into nature in our thinking because the laws that govern events in nature shine out for us. We then have an immediate justifiable awareness that we are in a world that somehow is. In our perceptions we feel ourselves, too, to be entities that are in existence.
