How does Complexity Develop?

Conference paper
Part of the NATO Science Series book series (NAII, volume 121)


A great variety of answers springs to mind in response to this question. They range from the simple idea that multiplying simple processes results in more complex causality through the “chaotic” divergence of interactive systems, so that the space between the piano keys comes to include new keys, to recursive systems that change their parameters each time around and indeed to recursive systems that change their rules as they evolve. This is not only a philosophical question, interesting for itself but without application to the everyday world. We are surrounded by systems becoming more complex, from embryos and ecosystems to industrial processes and international law.
