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

Approaches to gaining knowledge existed in earlier times of human evolution that can no longer be considered valid in the present age of natural science, possibilities of learning something of the world’s secrets from the content of dream life. Those times have passed, however. I will have something to say about this in the later lectures. Today, someone who has disciplined his thinking by the methods used to observe nature will specifically need to bring the kind of inner experience to mind which we have in our dreams.
