Yes, timely link:) I've added it to a recent post called Total Control.
I'm enjoying McKenna although I concede he's a recent find for me although I do have a long history of knowledge within the entheogen field in general. The only criticism I have of him so far is that he hasn't delineated enough about what he means by a return to the archaic​. My view is that experiences like nonduality actually came out of prerational archaic consciousness and that is indeed what people are experiencing when they experience this state. In part, that is why I don't subscribe​ to the recent spiritual trend of nonduality and remain within the camp of ontological dualism​. I do, however, feel that archaic​ modes of consciousness do need to 'supplement' newer modes like reason and logic as modernity through these faculties has led to reductionism and materialism​ and the turning of humanity into objects of financial exploitation.
