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

We then investigate—as I said, I am characterizing the route taken for conclusive evidence—what it is in the human soul that makes us come up against such limits. And you will find that there are indeed powers in the soul which prevent us from entering wholly into energy and matter, for instance, when seeking insight through thinking. The moment we truly want to enter wholly into them, the constitution of our own psyche prevents us from going all the way in our thinking. We need other powers of soul to take in such things as energy and matter and to unite with them. We need to bring in our sentient faculties, views, something related to feeling that cannot be reached in the immediate light of thought in our thinking. You then feel, in an immediate and living way, that this transition from thinking to dim feeling sets the limits for gaining ideas in natural science.
