%A Andrei Kirilyuk %O 1 page; Comment on the essay article by George Ellis "Physics, Complexity and Causality" (Nature 435, 743; 2005) %T Realistic description of causality in truly complex hierarchical structures %X In his recent essay article entitled "Physics, Complexity and Causality" (Nature 435, 743; 2005) George Ellis states that despite well-known successes of physics "we still do not have a realistic description of causality in truly complex hierarchical structures". Whereas one can only support the author's view that such description is increasingly desirable, the main statement suffers from essential incompleteness, since a realistic, mathematically rigorous and universally applicable description of detailed cause-effect links in truly complex systems, including e.g. emergent consciousness dynamics, does exist and is easily accessible through internet sources. As these results have been successfully presented at many international conferences (and even published!), the true problem is not the absence of realistic complexity description, but its intentional neglect, without any scientific objection, by the same physics establishment that insists (rightly) upon the necessity of that "new kind of science". As today's science has started to strongly modify the whole depth of unreduced dynamic complexity at all its levels using purely empirical, blind technology, further intentional rejection of consistent understanding of the real world complexity inevitably leads to destructive, catastrophically growing consequences. %D 2005 %K Unreduced dynamic complexity; universal science of complexity; emergent consciousness; causally complete knowledge %L cogprints4471
