All of the models and techniques of NLP are based on the combination of these two principles. In the belief system of NLP it is not possible for human beings to know objective reality. Wisdom, ethics and ecology do not derive from having the one 'right' or 'correct' map of the world, because human beings would not be capable of making one. Rather, the goal is to create the richest map possible that respects the systemic nature and ecology of ourselves and the world we live in. The people who are most effective are the ones who have a map of the world that allows them to perceive the greatest number of available choices and perspectives. NLP is a way of enriching the choices that you have and perceive as available in the world around you. Excellence comes from having many choices. Wisdom comes from having multiple perspectives.
