106 Intuitive Thinking as a Spiritual Path
We can give content to this hypothetical world principle
only by borrowing content from the world of experience
and then deceiving ourselves about this fact. Otherwise,
it remains a concept devoid of content and has only the
form of a concept. At this point, dualistic thinkers usually
maintain that the content of the concept is inaccessible to
our cognition: we can know onlythat such content exists;
we cannot knowwhat exists. In either case, overcoming
dualism is impossible. Even if we import a few abstract
elements from the world of experience into the concept of
the thing-in-itself, it still remains impossible to trace back
the rich, concrete life of experience to a few qualities that
themselves are only borrowed from perception.
Du Bois-Reymond thinks that unperceivable atoms of
matter create sensation and feeling by their position and
movement.^1 He uses this to arrive at the conclusion that
we can never have a satisfying explanation of how mat-
ter and motion create sensation and feeling. Thus he
writes:
It is completely and forever incomprehensible
that a number of atoms of carbon, hydrogen, nitro-
gen, oxygen, etc., should be other than indifferent
as to how they are lying and moving, how they lay
and moved, and how they will lie and move. There

both for his investigations of animal electricity, the physiology of mus-
cles and nerves, and metabolic processes and his famous “ignorabi-
mus”—we cannot know. SeeThe Riddles of Philosophy (p. 319 ff.)
