Spirit moves on. Evolution continues to unfold, leaving nothing in the manifest world untouched. And the great traditions are just that — traditions — some of whose insights have stood the test of time, and some of which most definitely have not.
Integral studies must therefore fight on two fronts, as it were: against a modernity that is slow to recognize the full spectrum of consciousness, and against a traditionalism that refuses to recognize any substantial advances made by modernity itself.
