If you believe, as I do, that we are at root children of God, trapped, as Pascal put it, between being angels and beasts, then there will be moments in our lives when we are closer to being angels and closer to being beasts. In my view, our beastliness, as it were, is a function of our contingency as evolving primates, having to tackle a terrifying world of death, disease, war, hatred, and fear with intelligence and self-control and self-defense. This is the world of the first half of Hobbes’ Leviathan.
But we are also more than that, as Jesus taught us. We are children of God. Our alienation is because something deep within us yearns to come home, a home we do not remember, but we know exists. What psilocybin seems to do is remove the veil from seeing and accepting this wondrous, difficult truth. It does not add something to our consciousness that isn’t already there. It simply calms the noise around it so we can hear what is already within us. Hence the parallels between brains in deep meditation and brains on psilocybin.
