Popper's demarcation of:
Non-science or Pseudo-science
observation, hypothesis, testing
looks for confirmation not falsification
immunized against criticism
based on truthfulness
Science
consists of: bold (daring, unacceptable) conjecture
can be falsifiable
takes the risk of clashing with reality
its results: regarded as approximations
e.g.: Marxism, Adler's/Freud's psychoanalysis
e.g.: devoted scientists: Kepler, Einstein
never satisfied with own results
