four kinds of relationship between knower and known

• the uncertainty principle: to know something about an object, an observer must act upon, and thus disturb it ... act of knowing is thus a transaction between the object and the knower which involves physical exchanges of energy ... dynamic confrontation between knower and known, with the addition oft h e two kinds of relation between them - the objective information (sense d a t a coming from the object

• causes, categories, or kinds of relationships between an observer and an object (our basic categories of knowing, or four aspects of a situation):
  • AA) contained within the object, its formal description (objective general);
  • AB) the sense data (D) received from the object by direct encounter, such as weight, color, texture (objective particular);
  • BA) qualities (values) which the knower projects (P) upon the object (projective general)[^BA];
  • BB) the function of the object to the knower, knower's interest (projective particular).
• only (AA) is considered valid and useful in the scientific view for a valid description .. scientific knowledge is derived from observations, but is different from them.
• four directions independent and opposed aspects

[^BA]: supplanting the word "subjective" by "projective" — earlier implies a personal description, with the possibility of illusion, while later implies only that which is not objective, and leaves aside the question of reality
