The whole non-problem of spirit-matter dualism is ill-conceived, arising from our grammatical brainwashing in the subject-predicate patterns of language hardwired into the Indo-European mind, which we then project as the inherent dualism of our syntax onto the observed world of things. The truth is that there is nothing outside experience, and so the "fact" of the material world is always already enclosed within the epistemological brackets of consciousness. I would recommend checking out the work of Donald Hoffman and Bernardo Kastrup for a more comprehensive explanation of this view. Spirit and matter are not two non-overlapping magisteria, as the mental trompe l'oeil of Cartesianism would have us believe, but the non-dual ontological modality of measuring-measured, observing-observed, thinking-thought. Understood in this way, the whole "hard problem of consciousness," and other pseudo-controversies in philosophy, simply evaporate in the pure light of a non-dual wisdom that is not beholden to grammar. Non-duality reveals the observer and the world observed as a seamless whole that is utterly embraced by the hypokeimenon of consciousness, which admits of the singular, non-dual property of transjectivity (the ontological non-duality of active and passive valences of being).
Is this a post-modernist giving a lecture about prophets? How ironic is that. It baffles me that one get a PhD in philosophy or theology and still know nothing of God or the nature of reality.
Just curious, which specific passage from the Seven Valleys or the Four Valleys is Dr. Phelps referring to at 1:21:37, about the seekers of one valley viewing those of the previous as idolaters or impious? Thanks.
