Human beings begin their evolution through the great spiral of consciousness, moving from archaic to magic, to mythic to rational to perhaps integral, and from there perhaps into genuinely transpersonal domains. But for every person that moves into integral or higher, dozens are born into the archaic. The spiral of existence is a great unending flow, stretching from the body to mind to soul to spirit, with millions upon millions constantly flowing through that great river from source to ocean.
No society will ever simply be at an integral level because the flow is unceasing, although the center of gravity of a culture can indeed drift upward as it has over history. But the major problem remains not, how can we get everybody to the integral wave or higher, but how can we arrange the health of the overall spiral as billions of humans continue to pass through it, from one end to the other, year in and year out.
Ken Wilbur, in his book The Theory Of Everything, does an excellent job describing the contrast that exists within human consciousness. We are all born into the archaic state of consciousness, and then move through different stages as our awareness expands. Age, influences and associations expand our awareness. Some of us find a niche of some sort in a particular stage and stay there. Our beliefs influence that decision.
Once we feel comfortable in a certain stage we have a tendency to attack other stages in several ways. The type of attack depends on the influences and associations that surround our beliefs. Some levels are more aggressive than others; some are more agreeable than others. All stages are experienced by us as we expand in awareness, but that expansion may not happen in one lifetime.
Each form of consciousness has its own codified system within a particular electromagnetic light range. That means there will always be different levels interacting at the same time in this unique state of reality. We choose to experience this type of reality to the emotional feel the probabilities that develop from the contrast created by different stages of awareness. It is a natural learning process inherent in our particular type of consciousness.
