"We exist on many levels at the same time, Doctor. This level...” I gestured to the room and its objects. “... the space/time continuum, I believe you call it, is perhaps the narrowest and least dimensional of all. But it’s the one in which we choose to relate to each other as corporeal beings in a defined material space measured by units of time. It serves a purpose, yes, but it’s a purpose that’s been determined by our interaction on other levels, deeper and more complex than this one."
