“The aim of this book is to show that the world, including human beings and their consciousness, is not originally a world of thing but a world of words; that fundamentally the world has the structure of a text; and that it is therefore possible to read it like a test.” ― Georg Kühlewind To realize this goal, one must bear in mind three different approaches, or epistemology, psychology, and linguistics. These are united by the phenomenology―“empiricism of consciousness”―used by the author, who always speaks from and toward experience. This is not an ordinary text, but a guide to philosophical experience―to the experience of cognition itself.
