III. Thinking in the Service of Understanding the World

Observation and thinking are the two points of departure for all spiritual striving of man insofar as he is conscious of such striving. What is accomplished by ordinary human reason as well as by the most complicated scientific investigations rests on these two fundamental pillars of our spirit. Philosophers have started from various primary antitheses: idea and reality, subject and object, appearance and thing-in-itself, ego and non-ego, idea and will, concept and matter, force and substance, the conscious and the unconscious. It is easy to show, however, that all these antitheses must be preceded by that of observation and thinking, as the one the most important for man.
