“Why Emergence Matters”
p. 75
Early modem science sought to reduce all natural phenomena to matter
and the laws of physics. But a shift of emphasis has taken place in the
last decades. Scientists now recognize nature’s tendency to produce
more and more complex forms of organization, not all reducible to
fundamental laws. This new “non-Reductionist” picture of the world
gives rise to some rather different assessments of the goals and
methods of the biological sciences.
Jesper Hoffmeyer
“Why Do We Need a Semiotic Understanding of Lite?”
p.152
Biosemiotics is based on an understanding of agency as a real property
of organic life, a property that is ultimately rooted in the capacity
of cells and organisms to interpret (whether consciously or
unconsciously) events or states as referring to something other than
themselves or, in other words, the capacity to interpret signs.
p. 162
A semiotic understanding of animate nature will potentially influence
science and culture in important ways. Above all, it will strengthen
our human feeling of relatedness to the other creatures of this world
and our belonging in the biosphere. The image of animals and plants as
stupidly obedient slaves of simple survival schemes will dwindle and be
replaced by an understanding of, and an admiration for, the marvelous
semiotic interaction loops through which organisms pursue their
interests. Living beings are not the senseless and ignorant machines
that science has taught us they are, and in the long run this can well
have profound implications for how we treat natural systems.
"Networkologies: A Philosophy of Networks for a Hyperconnected Age—A Manifesto"
Christopher Vitale, Zero Books, 2014
p. 11
The project to develop an entire worldview based on networks luckily
does not have to start from scratch. During the second half of the
twentieth century, the science and mathematics of networks, a major
component of what is often called “complex systems science,’ began to
revolutionize a variety of fields of study in a manner which continues
today, and which can provide a starting point for this project.. . .
Complex systems science is a relational
and network-oriented approach to scientific thinking. Opposed to
various forms of “reductionism,” complex systems research shows how
modes of interaction between relatively simple parts can give rise to
highly complex behaviors.
p. 16
What could it mean, then, for something to be networked, whether as an
aspect of the world being diagrammed, or as a diagram itself?
At its simplest a network is any whole, composed of parts.
Distinguished from a background, and composed of other parts and
wholes, layered into each other at multiple levels of scale. Anything
which can be thought of in this way can be seen as a network, which is
a general way of thinking about how things intertwine, interact, and
hold together.
20
Everything in the world can be seen as a network, and in this sense, to
call anything in the world a network simple means to see it
relationaly: as a network composed of networks, linked to others,
layered in levels, against a ground, and as an aspect of various
processes and reifications. Networks are then, more than anything, a
way of looking at the world, a shift in perspective, a lens which makes
everything appear networked.
22
According to complex systems science, self-organization is promoted by
a particular set of conditions, which include: diverse components,
distributed organization, meta stability, and feedback between aspects
and environment in a manner which is itself diverse, distributed, and
meta-stable. Thereby potentiating sync between aspects, the emerging
whole, and environment. When all these conditions are met, not only
will a system spontaneously self-organize to greater complexity it will
generally continue to do so, at least until one of these factors begins
to fall out of sync with the others.
p. 24
When complex systems self-organize in ways which increase their
complexity, whether in quantity or quality, this is what complex
systems science calls emergences. Emergence itself comes in many
degrees and forms. A whirlpool is an example of the emergence of a
simple physical complex adaptive system, if one which is relatively
short-lived. Living organisms are more developed forms of emergence,
and they can give rise to new forms of emergence in turn, such as
learning and evolution, none of which could be predicted by an
examination of the structure of any particular part of the organism or
its brain, but only by the relational intertwining between these in
particular sets of circumstances. Beyond physical and biological
emergences, cultural advancements can also be seen as forms of
emergence, from flocking of birds to the development of language in
humans, and all of these feed back into physical and biological
emergences to potentiate them further.
p. 25
While all systems ultimately steal energy and materials from their
environment, such as the manner in which all life on Earth feeds off
the sun, robust systems are those which are able to grow and develop in
relation to their environment in the least destructive and maximally
creative ways, establishing feedback relations with their environment
so that they do not destroy the conditions for the emergence of
themselves or their environments in the present or future.
p. 30
What the new science of networks has shown then, and artificial neural
networks in particular, is that the types of experience given rise to
by the human brain can be produced from the networking of the stuff of
the world with itself. What matters isn’t what is networked, but how.
Nothing less, and nothing more. This could possibly change the way we
see almost everything.
p. 32-33
Rather than mere materialism, the perspective opened up by these
developments allows us to see the world and everything in it as the
result of complex networking. For if the potential for mind is simply
the result of the networking of neurons, essentially living wires, and
these are themselves the result of the dynamic networking of matter and
energy, which are themselves networks of quantum events, then this
means that the potential for human experience, and all we have ever
felt or even dreamed lies not in what things are, but in how they are
intertwined. That is, what something is and what it can do is
determined by how it networks, from molecule to emotion and thought and
everything in between. If the human mind can be seen as produced by the
networkings of matter, then so can anything else we have ever known.
From such a perspective, every aspect of our world can then be seen as
having infinite potential for emergence in and from itself, even if
this can only ever be unleashed by means complex robust networkings
"The Web of Life: A New Scientific Understanding of Living Systems"
Fritjof Capra, First Anchor Book, 1996
Fritjof Capra
p. 82
Having appreciated the importance of pattern for the
understanding of life, we can now ask: Is there a common pattern of
organization that can be identified in all living systems? We shall see
that this is indeed the case. This pattern of organization, common to
all living systems, will be discussed in detail below. Its most
important property is that it is a network pattern. Whenever we
encounter living systems-organisms, parts of organisms, or communities
of organisms-we can observe that their components are ranged in network
fashion. Whenever we look at life, we look at networks.
. . .
The first and most obvious property of any network is its
non-linearity-it goes in all directions. Thus the relationships in a
network pattern are nonlinear relationships. In particular, an
influence, or message, may travel along a cyclical path, which may
become a feedback loop. The concept of feedback is intimately connected
with the network pattern. I6
Because networks of communication may generate
feedback loops, they may acquire the ability to regulate themselves,
for example, a community that maintains an active network of
communication will learn from its mistakes, because the consequences of
a mistake will spread through the network and return to the source
along feedback loops.
p. 83
Thus the community can correct its mistakes, regulate itself, and
organize itself. Indeed, self-organization has emerged as perhaps the
central concept in the systems view of life, and like the concepts of
feedback and self-regulation, it is linked closely to networks. The
pattern of life, we might say> is a network pattern capable of
self-organization. This is a simple definition, yet it is based on
recent discoveries at the very forefront of science.
"A Third Window: Natural Life beyond Newton and Darwin"
Robert E. Ulanowicz, Templeton Foundation Press, 2009
p. 8
If we wish to avoid a bad end, then maybe, just maybe, we should pause
and reconsider our directions. The foregoing considerations suggest
that we may harbor an inadequate or inaccurate image of reality, and so
we might begin by scrutinizing our (mostly unspoken) assumptions
concerning how nature acts. Although a legion of books is available
describing the scientific method, works that elaborate and critique the
underlying postulates (metaphysics) of conventional science remain
scarce by comparison .
p. 11
I argue that we need to shift emphasis away from objects and focus rather upon configurations of processes
p. 25
To the best of my experiencIt is no exaggeration to say that the
Newtonian worldview is in tatters. Unfortunately, surprisingly few of
us seem willing to admit this condition. It is poignant to ask,
therefore, what has arisen that can take the place of the Newtonian
framework. As we shall see, there have been a number of thinkers who
have suggested fertile new directions, but none has been accorded
widespread attention. Rather, what one encounters among the scientific
community is that most of us by and large cling to some dangling
threads of the Newto nian worldview. Its just that there remains no
widespread consensus about how much weight, if any, should be given to
each assumption
"Networks: A Very Short Introduction"
Guido Caldarelli, Michele Catanzaro, Oxford UP, 2012

Many emergent phenomena rely crucially on the structure of the
underlying networks. The network approach focuses all the attention on
the global structure of the interactions within a system. The detailed
properties of each element on its own are simply ignored. Consequently,
systems as different as a computer network, an ecosystem, or a social
group are all described by the same tool: a graph, that, is, a bare
architecture of nodes bounded by connections. . . .
P. 65
All these examples share with networks one basic feature: they are the
outcome of a complex, largely unsupervised process. Heterogeneity is
not equivalent to randomness. On the contrary, it can be the signature
of a hidden order, not imposed by a top-down project, but generated by
the elements of the system. The presence of this feature in widely
different networks suggests that some common underlying mechanism may
be at work in many of them’ Understanding the origin of this
self-organized order is one of the central challenges of the science of
networks.
"Complexity: Avery Short Introduction"
John H. Holland, Oxford UP,. 2014
p. 2
Each of these complex systems exhibits a distinctive property called
emergence, roughly described by the common phrase ‘the action of the
whole is more than the sum of the actions of the parts .
p. 5-6
The behaviors of complex systems:
Complex systems exhibit several kinds of telltale behavior. I will
describe some of these behaviors briefly here; they will be examined in
more detail in later chapters.
-Self-organization -- into patterns, as occurs with flocks of birds or schools of* fish
-chaotic behavior -- where small changes in initial conditions (‘the
flapping of a butterfly’s wings in Argentina’) produce large later
changes (‘a hurricane in the Caribbean’)
--‘fat-tailed’ behavior, v/here rare events (e.g. mass extinctions and
market crashes) occur much more often than would be predicted by a
normal (bell-curve) distribution
--adaptive interaction -- where interacting agents (as in markets or
the Prisoner’s Dilemma) modify their strategies in diverse ways as
experience accumulates.
In addition, as already mentioned, emergent behavior is essential requirement for calling a system ‘complex’.
"Reinventing The Sacred: A New View of Science, Reason, and Religion"
Stuart A. Kauffman, Basic Books, 2008
Ix
The title of this book, Reinventing the Sacred, states its aim. I will
present a new view of a fully natural God and of the sacred, based on a
new, emerging scientific worldview. This new worldview reaches further
than science itself and invites a new view of God, the sacred, and
ourselves ultimately including our science, art, ethics, politics, and
spirituality. My field of research, complexity theory, is leading
toward the reintegration of science with the ancient Greek ideal of the
good life, well lived. It is not some tortured interpretation of
fundamentally lifeless facts that prompts me to say this; the science
itself compels it.
This is not the outlook science has presented up to now.
Our current scientific worldview, derived from Galileo, Newton, and
their followers, is the foundation of modem secular society, itself the
child of the Enlightenment. At base, our contemporary perspective is
reductionist: all phenomena are ultimately to be explained in terms of
the interactions of fundamental particles.
X
Reductionist worldview led the existentialists in the mid-twentieth
century to try to find value in an absurd, meaningless universe, in our
human choices. But to the reductionist, the existentialists’ arguments
are as void as the space-time in which their particles move. Our human
choices, made by ourselves as human agents, are still, when the full
science shall have been done, mere happenings, ultimately to be
explained by physics.
In this book I will demonstrate the inadequacy of
reductionism. Even major physicists now doubt its full legitimacy. 1
shall show that biology and its evolution cannot be reduced to physics
alone but stand in their own right. Life, and with it agency, came
naturally to exist in the universe. With agency came values, meaning,
and doing, all of which are as real in the universe as particles in
motion. ‘Real” here has a particular meaning: while life, agency,
value, and doing presumably have physical explanations in any specific
organism, the evolutionary emergence of these cannot be derived from or
reduced to physics alone. Thus, life, agency, value, and doing are real
in the universe. This stance is called emergence. ,. . .
Emergence is therefore a major part of the new scientific
worldview, Emergence says that, while no laws of physics are violated,
life in the biosphere, the evolution of the biosphere, the fullness of
our human historicity, and our practical everyday worlds are also real,
are not reducible to physics nor explicable from it, and are central to
our lives. Emergence, already both contentious and transformative, is
but one part of the new scientific worldview I shall discuss....
p. 60
Self-organization may require that we rethink all of evolutionary
theory, for the order seen in evolution may not be the sole result of
natural selection but of some new marriage of contingency, selection,
and self-organization. New biological laws may hide in this union.
p. 281-282
\fi/e are beyond reductionism: life, agency, meaning, value, and even
consciousness and morality almost certainly arose naturally, and the
evolution of the biosphere, economy, and human culture are stunningly
creative often in ways that cannot be foretold, indeed in ways that
appear to be partially lawless. Hie latter challenge to current science
is radical. It runs starkly counter to almost four hundred years of
belief that natural laws will be sufficient to explain what is real
anywhere in the universe, a view I have
called the Galilean spell. The new view of emergence and ceaseless
creativity partially beyond natural law is truly a new scientific
worldview in h science itself has limits. And science itself has found
those very limits. In this partial lawlessness is not an abyss, but
unparalleled freedom, unparalleled creativity. Can only understand the
biosphere, economic evolution, and culture retroactively, from a
historical perspective . Yet we must live our lives forward, into that
which is only partly knowable. Then since reason truly is an
insufficient guide, we truly must reunite our humanity. And if so, we
truly need to reinvent the sacred for ourselves guide our lives, based
on the ultimate values we come to choose. At last, we must be fully
responsible for ourselves, our lives, our actions, our values, our
civilizations, the global civilization.
"Signs of Life: How Complexity Pervades Biology"
Richard Sole and Brian Goodwin, Basic Books, 2000
p. x
The concept of emergence, once regarded by many biologists as a vague
and mystical concept with dangerous vitalist connotations, is now the
central focus of the sciences of complexity. Here the question is, How
can systems made up of components whose properties we understand well
give rise to phenomena that are quite unexpected?
p. Xi
What we are seeing is the beginning of a science of emergent forms.
This is a new biological frontier that will leave its mark on the life
sciences and then transform into something else. But it is likely to
have longer* term consequences on our view of science itself. It will
become evident that the new understanding of complex processes takes us
beyond the traditional scientific perspective of prediction and control
of nature, to a relationship of participation in natural processes that
are unpredictable, though still intelligible.
p. 18
Self-organizing behavior emerges unpredictably in systems at different
levels. We make it intelligible recognizing how it is consistent with
lower-level properties and by finding appropriate mathematical
descriptors. But in doing this dosen’t reduce a whole to the properties
of its parts and their interactions.
p. 19
We believe that reductionism is inadequate as the primary explanatory
framework of science, progress in understanding natural in interaction.
It often involves grasping relevant aspects of whole systems and
finding appropriate mathematical descriptors that capture these
properties.
p. 28
The sciences of complexity show us that we are embedded in a world
fundamentally different from that which has previously characterized
modem science, with its emphasis on prediction and control of nature.
We can clearly exercise what ever control remains possible in complex*/
systems. But there are other options, such as participating rather
controlling, that is, recognizing that we an influence complex systems
and proceeding- cautiously with such mental unpredictability of our
actions no longer be naïve observers who live outside the phenomena we
manipuIate.
"Complexity : A Guided Tour"
Melanie Mitchell, Oxford UP, 2009
p. ix
REDUCTIONISM HAS BEEN THE DOMINANT approach to science .since the
1600s. Rene Descartes, one of reductionism $ earliest proponents,
described his own scientific method thus: to divide all the
difficulties under examination into as many parts as possible, and as
many as were required to solve them in the best way and to conduct my
thoughts in a given order, beginning with the simplest and most easily
understood objects, and gradually ascending, as it were step by step,
to the knowledge of the most complex”1
Since the time of Descartes, Newton, and other
founders of the modem scientific method until the beginning of the
twentieth century, a chief goal of science has been a reductionist
explanation of all phenomena in terms of fundamental physics. Many late
nineteenth-century scientists agreed with the
p. X
But, twentieth-century science was also marked by the demise of the
reductionist dream. In spite of its great successes explaining the very
large and very small, fundamental physics, and more generally,
scientific reductionism, have been notably mute in explaining the
complex phenomena closest to our human-scale concerns.
Many phenomena have stymied the reductionist program: the
seemingly irreducible unpredictability of weather and climate; the
intricacies and adaptive nature of living organisms and the diseases
that threaten them; the economic, political, and cultural behavior of
societies; the growth and effects of modem technology and
communications networks; and the nature of intelligence and the
prospect for creating it in computers. The antireductionist
catch-phrase, “the whole is more than the sum of its pans, takes on
increasing significance as new sciences such as chaos, systems biology,
evolutionary economics, and network theory move beyond reductionism to
explain how complex behavior can arise from large collections of
simpler components.
By the mid-twentieth century, many scientists realized
that such phenomena cannot be pigeonholed into any single discipline
but require an interdisciplinary understanding based on scientific
foundations that have not yet been invented. Several attempts at
building those foundations include (among others) the fields of
cybernetics, synergetics, systems science, and, more recently, the
science of complex systems.
p. 12
Common Properties of Complex Systems:
When looked at in detail, these various systems are quite different,
but viewed at an abstract level they have some intriguing properties in
common:
1. Complex collective behavior: All the systems I
described above consist of large networks of individual components
(ants, B cells, neurons, stock-buyers, Web-site creators), each
typically following relatively simple rules with no central control or
leader. It is the collective actions of vast numbers of components that
give rise to the complex, hard-to-predict, and changing patterns of
behavior that fascinate us.
2. Signaling and information processing: All these
systems produce and use information and signals from both their
internal and external environments
3. Adaptation: All these systems adapt—that is,
change their behavior to improve their chances of survival or
success—through learning evolutionary processes.
Now I can propose a definition of the term complex
system: a system in which large networks of components with no central
control and simple rules of operation give rise to complex collective
behavior, sophisticated information processing, and adaptation via
learning or evolution. . . .
Systems in which organized behavior arises without an
internal or external controller or leader are sometimes called
self-organizing. Since simple rules produce complex behavior in
hard-to-predict ways, the macroscopic behavior of such systems is
sometimes called emergent. Here is an alternative definition of a
complex system: a system that exhibits nontrivial emergent and
self-organizing behaviors. The central question of the sciences of
complexity is how this emergent self-organized behavior comes about.
