The first lecture should give you a good idea, but if you're looking for discussion, I'd be willing to have it but we'd be here for hours. We'd have to get into philosophy and define terms like "science", "God", "society", etc. We'd then have to explore psychology and models of consciousness, like Jungian archetypes and Freud's subconscious. We could also cover biology and how some substances trigger spiritual experiences that have positive life-changing effects. All the while, we could relate these discussions to the stories of the Bible or chapters of the Tao Te Ching and why they are both at the very least profound and contagious.
