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

Misunderstanding arises above all because investigators and thinkers committed to natural science, and people who imagine they are creating a philosophy based on natural science for themselves in a popular way, tend to think that anthroposophy is in opposition to natural science. I will try and show that the science of the spirit which is meant here is not only not in opposition to natural science but rather pursues the aims of natural science itself, right to its ultimate consequences, taking the spirit of the method of proving things that is used in natural science further than people do in natural science itself.
