"Cultural Maturity: A Guidebook for the Future" is the most detailed of three new future- related works by the author. It looks deeply at how the most important challenges ahead for the species will require not just better ideas, but new human capacities; in the end, an essential “growing up” as a species—a new Cultural Maturity. It is written for those interested in acquiring the newly sophisticated leadership abilities that we will more and more need in all parts of our lives in times ahead. The concept of Cultural Maturity makes understandable how institutional structures and beliefs that in modern times have served us well can’t be the ideals and end points that we have assumed them to be. It goes on to articulate a new guiding story for our time, one able to take us equally beyond denial, cynicism, and naïve wishful thinking. This book looks deeply at the changes the concept of Cultural Maturity describes—both how they make needed new capacities possible, and how we see their beginnings in many parts of our personal and collective lives. The concept of Cultural Maturity is based on the ideas of Creative Systems Theory, a comprehensive framework for understanding change, purpose, and interrelationship in human systems. Creative Systems Theory describes how Cultural Maturity’s changes are as, or more, significant than those that brought us modern democratic governance 250 years ago. It also argues that if the concept of Cultural Maturity is not basically correct, it is hard to imagine a healthy and vital human future. In addition to introducing the concept of Cultural Maturity, Cultural Maturity: A Guidebook for the Future presents important related ideas from Creative Systems Theory. Creative Systems Theory represents an example of culturally mature conception and offers a rich array of conceptual tools able to guide us in making the future’s increasingly complex choices.
