The importance of paradigms
1. It is necessary to have a paradigm in order to guide the
questions that are asked--otherwise, research &
conceptualization of problems would be aimless.
2) It is important to be aware of the assumptions or beliefs
that are implicit to the paradigm.
3) It is important to be aware of other available paradigms-other possible explanations.

understand the person from his/her frame of reference.

if conditions are right, will grow & develop.
Emphasis is on health, self-concept, self-actualization-humans have an inborn need for growth.
