Systems Science: “Thought About Thought”

For more than three decades Dr. Warfield studied systems and complexity. The product of his intense effort was the creation of Systems Science, described in “A Proposal for Systems Science” published in Systems Research and Behavioral Science in December 2003. 

His research concluded that systems science is a hierarchy of sub-sciences, all of which incorporate the “Fundamental Triangle of All Science.”

This Triangle consists of the human being, thought about thought, and language. Because most authors involve the three vertices of this triangle intuitively in their work, they make a variety of unsubstantiated assumptions related to them.

When complexity is involved, these assumptions typically misdirect their work, which explains why, after a century of study, no systems science had been developed and tested until Warfield’s version appeared.

A history of the evolution of “thought about thought” is found in Warfield’s An Introduction to Systems Science.

John Wheeler Saw the Tear in Reality

h/t Jason Hu

Until his dying days, the giant of 20th-century physics obsessed over the underpinnings of space and time, and how we can all share the same version of them.

When Johnny Wheeler was 4 years old, splashing in the bathtub in Youngstown, Ohio, he looked up at his mother and asked, “What happens when you get to the end of things?” The question would haunt him for the rest of his life. What happens when you get to the bottom of space? What happens when you get to the edge of time? It would lead him to suggest that space-time can’t be the true fabric of the universe. It would compel him, even in his final days, to search for some deeper reality beneath space-time and to wonder whether, somehow, that reality loops back to us.

Birger Sevaldson [dipl NCAD PhD] is a professor at the Institute of Design at the Oslo School of Architecture and Design (AHO), Institute of Design. He is trained as an interior architect and furniture designer. He has been practising in various fields of design, including architecture and interior design, furniture design, industrial design and art-based projects. He has a PhD in creative design computing and has been researching systems thinking in design since 2006. He is central in the development of Systems Oriented Design, and his research focus is to develop systems oriented design thinking and practice for meeting the increased challenges of globalisation and the need for sustainability. He publishes on various themes, including systems oriented design, creativity, and research by design. Birger is a member of the council of the Design Research Society and is the founder of the Relating Systems Thinking and Design Symposia and a co-founder of the Systemic Design Association.

This address will briefly rehearse the key ideas of those works and then consider the current state of the world. Examining the societary, political, economic and planetary challenges we are now facing it will examine thosechallenges from a cybernetic perspective and show how those ideas can support us in resolving ‘The Real Threat to “All We Hold Most Dear

Extract

Willard van Orman Quine once said that he had a preference for a desert ontology. This was in an earlier day when concerns with logical structure and ontological simplicity reigned supreme. Ontological genocide was practiced upon whole classes of upper-level or ‘derivative’ entities in the name of elegance, and we were secure in the belief that one strayed irremediably into the realm of conceptual confusion and possible error the further one got from ontic fundamentalism. In those days, one paid more attention to generic worries about possible errors (motivated by our common training in philosophical skepticism) than to actual errors derived from distancing oneself too far from the nitty-gritty details of actual theory, actual inferences from actual data, the actual conditions under which we posited and detected entities, calibrated and ‘burned in’ instruments, identified and rejected artifacts, debugged programs and procedures, explained the mechanisms behind regularities, judged correlations to be spurious, and in general, to the real complexities and richness of actual scientific practice

Abstract

I present a personal account of self-organizing systems. As such, it is necessarily biased and partial. Nevertheless, it should be useful to motivate useful discussions. The relevant contribution is not my attempts at answering questions (maybe all my answers are wrong), but the steps towards framing relevant questions to better understand self-organization, information, complexity, and emergence. With this aim, I start with a notion and examples of self-organizing systems (what?), continue with their properties and related concepts (how?), and close with applications (why?).
