In my view, no one integrates scientific and spiritual understanding better than Ken Wilber, and so I want to share portions of the interview with you, some quoted, some paraphrased. These capacities were taken up and included in animal life, which then added the capacities for mobility and an emotional and sexual life. Those capacities were taken up and included in humans, which then added the capacities for rational and conceptual thought.
Nothing is lost.
All is retained, enfolded, included, and embraced in each successive step. These include imagination, creative impulses, and dreaming, as well as intuition, incorporated in a new age of consciousness which depends less on knowledge from the five senses and more on openness to the reality that exists beyond sensory knowledge. This perspective does not reject rationality or downplay it, as many New Agers do. Wilber's time perspective attaches no dates, millennial or otherwise. There would seem to be no reason to expect that this stage of evolution would move any more rapidly than previous stages.
