Do I need to understand Creative Systems Theory to make use of the concept of Cultural Maturity?
No. As simple metaphor or analogy, the Cultural Maturity works fine as a stand-alone concept. The concept of Cultural Maturity is a formal Creative Systems Theory notion. And CST is significant with regard to the concept of Cultural Maturity because it models one successful effort at Culturally Mature theory (and one that can be applied in highly nuanced ways to a wide variety of questions). But there is no need to either understand or agree with the theory’s idea to make powerful use of it.
