Neal Stepheson's book: highly accessible SF explanation of the neo-Platonist multiverse. \\ Marvin Minsky's book: fundamental concept of minds as collections of semi-independent agents is very powerful. \\ Central to Robert Rosen's work (2005) is the idea of a complex system, defined as any system that cannot be fully understood by reducing it to its parts. Complexity refers to the causal impact of organization on the system as a whole. Since both the atom and the organism can be seen to fit that description, Rosen asserts that complex organization is a general feature not just of the biosphere on Earth -- but of the universe itself. - Adriano
