“You inhabit the land you know, pragmatically and conceptually. But imagine what lies just outside of that. There exists an immense space of things you do not know, but which other people might comprehend, at least in part. Then, outside of what anyone knows, there is the space of things that no one at all knows. Your world is known territory, surrounded by the relatively unknown, surrounded by the absolutely unknown—surrounded, even more distantly, by the absolutely unknowable. Together, that is the canonical, archetypal landscape. The unknown manifests itself to you in the midst of the known. That revelation—sometimes exciting, but often quite painful—is the source of new knowledge. But a fundamental question remains: How is that knowledge generated? What is comprehended and understandable does not just leap in one fell swoop from the absolutely unknown to the thoroughly and self-evidently articulated. Knowledge must pass through many stages of analysis—a multitude of transformations—before it becomes, let us say, commonplace.”
