Pattern language, form language, general systems theory, R-theory

One of the challenges with the development of pattern languages is the cross-appropriation of approaches of techniques from one domain (i.e. built physical environments) into others (e.g. software development, social change).

The distinction between pattern language and form language is made by Nikos Salingaros.

Design in architecture and urbanism is guided by two distinct complementary languages: a pattern language, and a form language.

The pattern language contains rules for how human beings interact with built forms — a pattern language codifies practical solutions developed over millennia, which are appropriate to local customs, society, and climate.

A form language, on the other hand, consists of geometrical rules for putting matter together. It is visual and tectonic, traditionally arising from available materials and their human uses rather than from images. Different form languages correspond to different architectural traditions, or styles. The problem is that not all form languages are adaptive to human sensibilities. Those that are not adaptive can never connect to a pattern language. Every adaptive design method combines a pattern language with a viable form language, otherwise it inevitably creates alien environments.  [Salingaros, 2014]

The focus on form is apparent in the title of Notes on the Synthesis of Form [Alexander, 1964].  Form has geometry, that brings up the idea of “life” in The Nature of Order.

Chapter Five:  Fifteen Fundamental Properties

I have introduced the idea of life as something which may occur in any spatial system, and suggested that a degree of life which appears in a thing depends on the life its component centers and their density.

      Social Systems Science graduate students in 1970s-1980s with #RussellAckoff, #EricTrist + #HasanOzbehkhan at U. Pennsylvania Wharton School were assigned the Penguin paperback #SystemsThinking reader edited by #FredEEmery, with updated editions evolving contents.

    • Wholism, reductionism (Francois, 2004)
      Proponents of #SystemsThinking often espouse holism to counter over-emphasis on reductionism. Reading some definitions from an encyclopedia positions one in the context of the other (François 2004).
    • It matters (word use)
      Saying “it doesn’t matter” or “it matters” is a common expression in everyday English. For scholarly work, I want to “keep using that word“, while ensuring it means what I want it to mean. The Oxford English Dictionary (third edition, March 2001) has three entries for “matter”. The first two entries for a noun. The […]
    • Systemic Change, Systematic Change, Systems Change (Reynolds, 2011)
      It's been challenging to find sources that specifically define two-word phrases -- i.e. "systemic change", "systematic change", "systems change" -- as opposed to loosely inferring reductively from one-word definitions in recombination. MartinReynolds @OpenUniversity clarifies uses of the phrases, with a critical eye into motives for choosing a specific label, as well as associated risks and […]
    • Environmental c.f. ecological (Francois, 2004; Allen, Giampietro Little 2003)
      The term "environmental" can be mixed up with "ecological", when the meanings are different. We can look at the encyclopedia definitions (François 2004), and then compare the two in terms of applied science (i.e. engineering with (#TimothyFHAllen @MarioGiampietro and #AmandaMLittle, 2003).
