The brilliant British psychiatrist, neuroscientist,and mathematician Ross Ashby was one of thepioneers in early and mid-phase cybernetics
and thereby one of the leading progenitors of moderncomplexity theory. Not one to take either commonlyused terms or popular notions for granted, Ashbyprobed deeply into the meaning of supposedly self-organizing systems. At the time of the following article,he had been working on a mathematical formalismof his homeostat, a hypothetical machine establishedon an axiomatic, set theoretical foundation that wasVXSSRVHGWRRIIHUDVXIFLHQWGHVFULSWLRQRIDOLYLQJRUJDQLVPpVOHDUQLQJDQGDGDSWLYHLQWHOOLJHQFH$VKE\pVKRPHRVWDWKDGDVPDOOQXPEHURIHVVHQWLDOYDULDEOHVVHUYLQJWRPDLQWDLQLWVRSHUDWLRQRYHUDZLGHUDQJHRIHQYLURQPHQWDOFRQGLWLRQVVRWKDWLIWKHODWWHUFKDQJHGDQGWKHUHE\VKLIWHGWKHYDULDEOHVEH\RQGWKHUDQJHwhere the homeostat could safely function, a newoKLJKHUpOHYHORIWKHPDFKLQHZDVDFWLYDWHGLQRUGHUWRUDQGRPO\UHVHWWKHORZHUOHYHOpVLQWHUQDOFRQQHFWLRQVor organization (see Dupuy, 2000).
