As one studies these preconditions, one becomes saddened by the ease with which human potentiality can be destroyed or repressed, so that a fully-human person can seem like a miracle, so improbable a happening as to be awe-inspiring. And simultaneously one is heartened by the fact that self-actualizing persons do in fact exist, that they are therefore possible, that the gauntlet of dangers can be run, that the finish line can be crossed.
Abraham MaslowThe science of psychology has been far more successful on the negative than on the positive side... It has revealed to us much about man's shortcomings, his illnesses, his sins, but little about his potentialities, his virtues, his achievable aspirations or his psychological health... We must find out what psychology might be if it could free itself from the stultifying effects of limited, pessimistic and stingy preoccupations with human nature.
