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

I have thus called ‘will’ what we experience in our ordinary inner life; it is an inner perception, but is more and more considered to be beyond comprehension. ‘Scientific’ psychologists find that the forming of ideas, thinking, has a structure that relates to organic nature. However, as soon they move on from thinking and go just as far as feeling and then to the will, they will say: ‘Here we can at best speak of will or feeling as nuances’—Theodor Ziehen speaks of emotive colouring, ideal colouring—‘for here nothing can be found that might be analogous to sensory perception.’ The will is thus beyond comprehension, though it evidently exists. It is denied only by people who do not go by reality but by the things which they say they are able to grasp scientifically. Only causality has validity in natural science, and as the will does not function causally they will say it does not exist. Something is there, however, and does not go by what can be comprehended. That is merely human prejudice.
