Spiral Dynamics posits a series of stages through which human's cultural development progresses – from a survival-based hunter-gatherer stage to a magical-tribal-agrarian stage to a city-building-invading stage to a mythic-religious-empire stage to a rational-scientific-capitalist stage to a green-holistic-inclusive stage and then ascending to a second tier where all the previous stages are contemplated and integrated and a third transpersonal tier where a spiritual unity or Omega point is eventually reached, which all the other stages are struggling to embody.
