The subjective character of experience is integral. (Subjective in the sense means "as internally experienced", rather than 'arbitrary' or 'whimsical'). It is taken for granted that what people perceive, believe and feel, is more significant to their lives than what is objectively 'true', and takes for granted that each person's awareness and inner world is different and unique. It is emphasized that one must leave one's own preconceptions behind, and be willing to understand and work within the other person's "reality", to have any great effect, since no one map of reality can be said to be "true".
There is an order and a structured logic to it. But that order and logic varies individually and people interact and judge based upon their own understandings of the world, not upon some objective reality.
