Larc - after stage 1 you learn how to count...
FYI Carmel:
Maslow had a few different "models".
His "Educational Theory" consisted of 7 values. His "Hierarchy of Needs" consisted of 5 levels (the one which you quoted)
To arrive at his insights Maslow studied some of the greatest achievers through history. He reasoned that if you want to learn how to run faster, you have to study the fastest runners. In the same way, if you want to know how people can achieve greatness, the key is to study the greatest people. His teachers inspired the inquiry.
Although Maslow mentions Ayn Rand several times in his monumental Motivation and Personality, he was not a "declared" Objectivist. Nevertheless, his ideas are so vital and so closely aligned with Objectivism, that anyone interested in a rational view of human nature would be well served to read his works.
But thanks for the lesson...
Oh - one more thing....the first post in this thread - was written by Ayn Rand
