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

In the light of the immediate experience of genuine thinking which has been developed in the natural scientific discipline, nothing can be further from the truth than this. Anyone using the strictest form of thinking learned in natural science has to arrive at a different thesis: ‘I think’—and this refers specifically to thinking where one has withdrawn from the outside world—‘and therefore I am not.’ Any genuine position taken with regard to the spiritual world begins with realization of the truth that we get to know our non-existence as soul entities, the essential nature of our self, in so far as soon as we move to a thinking that is wholly abstracted we are not.
