“When we speak… about consciousness, about the point at which consciousness arose and so forth, we are speaking not merely about human nature, as we call it, but also about nature itself. When we study consciousness historically, contrasting perhaps what men perceive and think now with what they perceived and thought at some period in the past, when we study long-term changes in consciousness, we are studying changes in the world itself, and not simply changes in the human brain. We are not studying some so-called “inner” world, divided off, by a skin or a skull, from a so-called “outer” world; we are trying to study the world itself from its inner aspect. Consciousness is not a tiny bit of the world stuck on to the rest of it. It is the inside of the whole world.” -Owen Barfield (History, Guilt, Habit, p. 18).
