I started reflecting on what had happened to “complexity”, and whether there was something to leverage from the institutional structure that had grown up around it. Nearly 20 years after the publication of A New Kind of Science, what should “complexity” be now?
I wrote “Charting a Course for ‘Complexity’: Metamodeling, Ruliology and More”—and in doing so, finally invented a word for the “pure basic science of what simple rules do”: ruliology.
