I first came across Ken Wilber's work late in the last century when a friend handed me a copy of A Brief History of Everything as a birthday present. Since then, Wilber's influence has been cited by figures as diverse as Bill Clinton and Deepak Chopra, which should give you some idea of how broadly his work can be applied.
When it comes to religion, I have to confess to being a bit of a mongrel.
My mother was a Methodist. My father was a nudist. And I once called myself an immortalist.
These days I choose not to align myself with any particular religious group.
Human records indicate that some sort of belief in a God or collection of gods is a feature of almost all human culture. No matter what the continent or age, a belief in powerful, supernatural beings that somehow influence human existence is a near-constant.
At the same time, though, many skeptics have persistently questioned the existence of such a being, and beliefs about the attributes of God have exhibited wide variation, with such variations often being so deeply held that wars have been fought to advance one sort of belief over another.
We often seem to assume that people say things, and come to believe them, because they are true.
It seems to me, though, that people take up beliefs for a whole host of reasons, and the likely truth or falsehood of these statements is often the least of the motivating factors at work.
Here then, are the multifarious reasons why people may choose to believe something.
We tend to divide up human history into relatively neat periods, and give them names like “The Agrarian Era,” “The Age of Industrialization” and “The Information Age.”
A number of authors and systems of thought espouse one or another series of developmental levels, in fields of study as diverse as psychology, sociology, economics and organizational development. Ken Wilber was the first author I encountered who proposed an integration of these various developmental progressions into a single unifying scheme. However, much of Ken's take on these levels was heavily influenced by the Spiral Dynamics work done by Clare W. Graves, Don Beck and Chris Cowan.
