The
first three parts discuss how enterprise and business architects model the
reality of business operations. This
part addresses a more fundamental question: How do we acquire, verify and share
knowledge of reality? It is
for those with an intellectual curiosity about how systems thinking ideas
relate to ideas about knowledge, truth and the philosophy of science. It
underpins systems thinking with a psycho-biological view of description and
reality.
“A biological approach to human
knowledge naturally gives emphasis to the pragmatist view that theories
[descriptions of reality] function as instruments of survival.” Stanford Encyclopedia
of Philosophy
This final part looks at how we perceive reality and describe it in memories and messages. It presents the evolution of human society as a story that runs from biology through psychology, sociology and civilization to science and artificial intelligence. By relating theories of description and typification to human cognition and communication, it will give you some insights into how brains and social communication work, and insights into the nature of description (typification) and reality (instantiation). It answers a few philosophical questions in ways that favor some philosophical positions over others.

The
evolution of intelligence and civilization
On
description as typification
Sharing
knowledge and verifying truth
This chapter starts with the idea that
knowledge is a biological phenomenon. It describes the emergence of human
intelligence and civilization from the biological evolution of animals, with
reference to symbolic languages and the sharing of knowledge in writing. It
discusses the following three principles.
Knowledge and description evolved in
biological organisms
The
"second order cyberneticians" claimed that
·
knowledge
is a biological phenomenon (Maturana, 1970), that
·
each
individual constructs his or her own "reality" (Foerster, 1973) and
that
·
knowledge
"fits" but does not "match" the world of experience (von Glasersfeld, 1987).
Stuart
A. Umpleby (1994) The Cybernetics of Conceptual
Systems. p. 3.
A good regulator
has a description of what it regulates. Here, a regulator is an
animal or a machine that either has a model or has access to a model. So, read this triangle from left to right: regulators <have
and use> models, which <represent> systems.

Models <have
and use> <represent> Regulators <monitor
and regulate > Systems |
The question is not whether an animal or a
business has a model; it is how complete and accurate is the model? To which
the answers might be both “very incomplete and somewhat inaccurate” and
“remarkably, complete and accurate enough”. Thinking about this leads
inexorably to the view of description and reality outlined in the following
chapters.
This
chapter identifies three kinds of description (our main interest is in symbolic description) and
details the semantics of the epistemological triangle used to illustrate points
in other chapters. Read the triangle from left to
right: describers <create and use> descriptions, which <represent>
phenomena.

Our epistemology |
|
Descriptions <create and
use> <represent> Describers <observe
and envisage> Phenomena |
Descriptions created (in mind, in speech, in writing, in
mathematics, wherever) appear at the apex rather than the left of the triangle.
This
chapter may be seen as an academic aside of interest to those with a
mathematical bent. However, the type theory in this chapter may also be seen as
fundamental to, the foundation of, how we describe things. It is relevant to
the challenges of defining a “domain-specific language” for doing business, and
defining the data created and used by a business in an “enterprise data
architecture”.
To describe a thing is to typify it in
terms of types already understood
“No statement which
refers to a ‘reality’ transcending the limits of all sense-experience can
possibly have any literal significance” Chapter 1 of “Language truth and logic”
A J Ayer.

Every type is a description. There are several set and type theories. In our type theory, a type is an intensional definition; it is a description of
one set member.
Every description is a type
“The fact is that
one cannot in language point to an object without describing it… And in
describing a situation, one is not merely ‘registering’ a sense-content; one is
classifying it in some way or other, and this means going beyond what is
immediately given.” Chapter 5 of “Language truth and logic” A J Ayer.
A description is not categorical – it cannot
pin down a single object – since it applies equally to any object in universe
that shares the same description. E.g. Physicists say there is nothing in their
description of the universe that prevents parallel universes from existing.
Think of any particular thing; a molecule, a game of chess, a galaxy, whatever.
Write down a description of it. Perhaps the thing you have described is unique.
But there is nothing to prevent your description being realized in more than
one particular thing. To describe one thing is to create a type to which other
things might conform.
This
chapter outlines some information and communication theory. It features a WKID
hierarchy, and the principle that in symbolic communication, coding is
ubiquitous. It goes on to describe how message senders communicate, and so
share knowledge, with message receivers. It discusses the following two
principles.
A description is meaningful to an actor
only in the process of creating or using it.
Coding is ubiquitous in the creation,
sharing and use of symbolic descriptions. A brain can encode some
information in the structure of its memory, which becomes useful later, when
the brain decodes it, by reversing the encoding process. Similarly, a brain can
direct the mouth to encode some information in spoken words, which become
useful when a receiver hears and decodes the message (using the language it was
encoded in). The information/meaning in the structure of memory or message
exists in the processes of encoding and decoding it.
Ashby
observed that coding is ubiquitous in thought and communication. To create a
description is to encode a model that represents some feature(s) of a
phenomenon. To use a description is to decode it, then use it to respond to or
manipulate whatever is described.
We
share knowledge by verifying descriptions we share. We clarify the
information in a description by reducing noise and ambiguity, and verify the truth of information by empirical,
logical and social means.
In short, the
principles of description introduced above are.
·
Knowledge and description evolved in biological
organisms
·
A good regulator has a description of what it
regulates
·
Consciousness is a process that enables us to
compare the past, present and future.
·
To describe a thing is to typify it in terms of
types already understood
·
Every type is a description
·
Every description is a type
·
A description is meaningful to an actor only in
the process of creating or using it
·
Coding is ubiquitous in the creation, use and
sharing of symbolic descriptions
·
We share knowledge by verifying descriptions we
share
The final chapter
summarizes some implications of these principles for
·
system
architecture –
as defined in ISO/IEC 42010.
·
semiotics –
notably Peirce and Popper.
·
philosophy –
including the problem of universals
·
mathematics –
did numbers exist before life?
