Regular readers will know that I think there are so many family resemblances across systems, complexity, and cybernetics that it’s invidious and counter-productive to attempt to draw those broad distinctions (see https://stream.syscoi.com/2020/04/21/bringing-together-some-reason-and-old-threads-on-systemsthinking-is-complexity-is-cybernetics/ ).
Nevertheless, the reading list at https://stream.syscoi.com/2020/05/06/a-very-rough-and-partial-draft-systems-thinking-reading-list/ – which is is avowedly rough and partial – doesn’t have a lot of things called ‘complexity’ on there.
