Excerpts from Robert Rosen's last book notes:

["Judith Rosen" <***>]

I'm going to post a few things from his handwritten notes for the list. It's
short, but these were particularly stimulating thoughts he had put down on
paper, regarding complexity:

 "Complexity refers to differentiation in space and time"

"Two kinds of complexity? As cause and as effect?"

"Complexity = effect    and also   = causal agent"

"Phenotype of compleicy is a duality between objective and subjective"

"How complex? is How much causality goes through this subjective (creating a
LOOP)"

"Relative "sizes" of a system's objective and subjective"

"To acquire a function turns general-purpose into special-purpose"

I hope people find these as intriguing as I do!
