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

Anyone who takes the analogy to its conclusion will know that hollow spaces also have an influence. One would not assume anything that is not filled out and therefore hollow, to have no effect. As you know, if the air is withdrawn from the recipient of an air pump, the vacuum has an effect on the surrounding air, which will whistle as it rushes in. In the sphere of things, therefore, being hollow does not mean being without effect. We need not be surprised then if we stub our toe against a stone, for in its materiality the stone is a hollow space in the spirituality that fills the world. So much to give an indication. It does not enlighten us about matter, but it shows the road we must follow to gain such enlightenment.
