is the concept of sex

Dr. Ross: That appears to be an essophysical manifestation, sir.

O5-1: A what?

Dr. Ross pulls out a tape recorder, and hits 'Play'.

  I direct the Essophysics Department, which you all well know is concerned with embodiments — manifestations of concepts
  within reality. An embodiment of the concept "red" would carry all of the characteristics conceptually associated with
  that color, such as being angry, or desirable, or malevolent. This is a simplified method of conceptualizing what's
  actually going on here; a tangible object or entity embodies a memetic structure within the Noosphere by conforming to its
  idealistic ideatic shape.

  Simply put, an embodiment is a physical item that's shaped like an idea. And, given the progression of human intelligence
  and development, over time, that shape can change. This means that, if the essophysical nature of an entity is not readily
  apparent, it can be discerned by comparing that entity's change over time to changes in human conception and ideatic
  space; a correlation almost certainly indicates causation.

Dr. Ross stops the recording. The entire table nods in understanding thanks to the extremely clear explanation.

O5-6: Ah, that makes perfect sense. You're saying The Ethereal Skeleton is a manifestation of some concept, then?

***

Dr. Ross: Uh, okay. That would be correct, Shirley. When Project ANTIFUCK concluded, it appears to have disturbed the Noosphere to the point that some concept manifested itself on Earth, and in an extreme fashion too. Considering what we know about essophysics and The Ethereal Skeleton, it leaves us with only one candidate for the corresponding concept.

O5-1: (Interjecting) Which is…?

Dr. Ross: I believe that concept would be sex itself, One.
