III. Thinking in the Service of Understanding the World

In sequence of time, observation even precedes thinking. For even thinking we learn to know first by means of observation. It was essentially a description of an observation when, at the opening of this chapter, we gave an account of how thinking is kindled by an event and of how it goes beyond what is given without its activity. Whatever enters the circle of our experiences we first become aware of through observation. The contents of sensation, of perception, of contemplation, of feelings, of acts of will, of the pictures of dreams and fantasy, of representations, of concepts and ideas, of all illusions and hallucinations are given us through observation.
