Titsworth, et al. state, in their recent paper The Shower Scene from Alfred Hitchcock's "Psycho" as Exemplifying Baudrillards four fold simulacrum creation process state:

"there is no more reality because it is impossible to define a definite starting point for any of these relations."

referring to the spawning of various simulacra from an original, real, entity. Which proves more difficult?

1. Defining a starting point for a sequence of entities, or
2. Determining the starting point from the sequence?
