…talking of interestingly styled web pages, though this one is less extreme and run by the eminent Alexander Riegler, as is the journal Radical Constructivism, there’s a lot here…

The Key to Radical Constructivism

From W. Ross Ashby comes the famous Law of Requisite Variety which states that the variety of actions available to a control system must be at least as large as the variety of actions in the system to be controlled. Now, constructivism certainly comes in a huge variety of forms and versions. I felt challenged to get some grip on its sumptuousness — especially because people regularly ask me to provide some sort of overview. In fact they sometimes express their astonishment that what they considered a monolithic epistemology turns out to be a dappled one. I have to admit that also for me it took some time to recognize the jungle as such and some more time to find my way through it. Please find below a (certainly still crude) version of the requested guide. Suggestions and corrections are welcome.Refer to this pages as: Riegler, A.
