Hodges' Model: Welcome to the QUAD: ii WCCS26: World Conference on Complex Systems 20-22nd April

Hodges' model is a conceptual framework to support reflection and critical thinking. Situated, the model can help integrate all disciplines (academic and professional). Amid news items, are posts that illustrate the scope and application of the model. A bibliography and A4 template are provided in the sidebar. Welcome to the QUAD ...

ii WCCS26: World Conference on Complex Systems 20-22nd April

Day 1

Plenary Talk: Reda Benkirane - Lost in Complexity: Welcome to the Real World

A first slide considered Abraham Maslow's book The Psychology of Science and his thought on the "law of the instrument". Maslow's hierarchy of needs is a key primer for new students to many disciplines, including nursing, and psychology. The purpose of Benikrane's focus on instruments concerns the emergence of civilisation and roles of agriculture, and war in the rise of community at several scales from village, to cities, states and nations. In terms of flow the slides highlighted the next speaker Peter Turchin's END TIMES, and two books by Johann Chapoutot, LES IRRESPONSABLES, and FREE TO OBEY.

In response to the slide with Einstein's -

"We cannot solve our problems with the same thinking we used when we created them":

- may I please class 'health - care' as a world? The thought that the medical, bio-medical, and bio-psycho-social encourages, sees enacted, and sustained a : is this fit for the problems of the 21st century. I like the slide's heading 'Beyond Complexity'. Such is the pace of change, which is labelled 'progress' that each one of us wakes up momentarily stupified and lost in complexity.

Keynote Speaker: Peter Turchin - The Great Holocene
Transformation: What Complexity Science Tells Us About The Evolution of Complex Societies

Turchin's keynote reminded me of Jared Diamond's book Guns, Germs and Steel. Reading GGS I realised there is more to 'axes' than I thought, especially from the individual to collective scales. It appears that whichever label - academia, research or education - you would like to apply, they all need a conceptual framework. Just as, individually, we all need a model of self, others and the world. This was a marvellous journey, through millennia of humanities' evolution, social, and political development, all realised through complexity. While attractors are to the fore, architecture and archaeology are regular distractors for me. Reading Holocene then had me hooked. 

A fellow delegate and speaker I dined with a few times encouraged me to read 'END TIMES'. I will seek it out later this year, (the next Hay-on-Wye visit?). Turchin is seeking to account for how human societies have reached their current state of organisation. The role of self-protection, seeking food, shelter, co-operation are all factors, with the emergence of religions, and agriculture. Several theories to date were covered [including, cultural multilevel selection, see Wilson et al. (2023)], plus a major project on cultural evolution: The Seshat: Global History Databank. For all the current loss and misery, conflict has paid a major role in cultural and political development. The prefix 'macro' features here. There was a social scale (people): FROM 10s - in foraging bands through TO 100,000,000s large nation-states. Mention of levels of scale, took me back to the work of Mario Bunge. The application of the Hertzsprung-Russell 'main sequence' (H-R) diagram is a great idea. I think Olaf Stapleton, author of Star Maker would have approved. 

This itself, for me, is reason enough to read Turchin. There is evolutionary biochemistry too, which is required in terms of a systems account. Is there a reflection of a main sequence construct between the SOCIOLOGICAL and SCIENCES domain of Hodges' model? 

 It is incredible the way new findings are regularly pushing even further the dates of human milestones stepping-stones. Perhaps we should always view progress in this way, and enjoy the 'moment'. There is still the puzzle of ultrasociality, and how to explain it? Turchin is seeking a mathematical history, with a journal Cliodynamics. There is another SF reference here, in Asimov's psychohistory in the Foundation books, but with less emphasis upon maths. This is encouraging for Hodges' model, and the inevitable transdisciplinary approach these questions demand.
