The Nature & Sensitivity of Chaos
Chris King*
ABSTRACT
In this paper, the nature and sensitivity of chaos will be illustrated. Failure to appreciate the generative
nature of chaos has led to it being one of the last scientific frontiers to be discovered, over fifty years
after relativity and quantum theory. Far from being the nemesis of order, or the primal ooze in which
order is imposed, chaos is genesis of new form. Most complex systems arise from the mutual interaction
between chaos and order, through bifurcation. The eternal religious war of light and dark is very much
the battle of chaos as the dark ‘force’ and order as the principle of light.
Key Words: chaos, nature, sensitivity, order, new form, genesis, religious war.
The Mythology of Chaos
Chaos Gk. kaos abyss – to ‘yawn’or ‘gape’
In the Britannica Dictionary chaos is ‘a condition of utter disorder or confusion as the unformed primal
state of the universe’ citing either utter disorder and confusion or an unfathomable abyss as definitive.
The Concise Oxford speaks of ‘formless void or great deep of primordial matter, this personified as the
oldest of the Gods, utter confusion’. The Grollier Encyclopedia notes that in Greek mythology, Chaos
was the unorganized state, or void, from which all things arose. Proceeding from time, Chaos eventually
formed a huge egg from which there issued Heaven, Earth, and Eros (love). According to Hesiod's
Theogeny, Chaos preceded the origin not only of the world, but also of the gods. In Hebrew myth tohu
wabohu is the universe without form and void, as in Genesis 1:2:
And the earth was without form, and void;
and darkness was upon the face of the deep.
Barbara Walker likens chaos to the undifferentiated raw elements occupying the womb of the worldgoddess between destruction and recreation of the universe.
The eternal religious war of light and dark is very much the battle of chaos as the dark ‘force’ and order
as the principle of light. This is enacted in diverse myths of origin. In Babylon, Tiamat the feminine
primal abyss and ancient mother is overthrown by Marduk the youthful male slayer of chaos, in the
name of civic, and world order. The same theme extends to classic male combat myth in the cosmic
Zoroastrian war of dark and light which became in Jewish and later Christian thought the battle between

God and Satan which leads to Armageddon and the unveiling tumult of apocalypse. This opposition
between chaos and order is a fundamental misunderstanding of the natural condition.
(a) Sensitive dependence on initial conditions is illustrated by the Lorenz flow simulating turbulent
weather. Trajectories in the flow starting arbitrarily close at a have exponentially separated by b and are
in distinct parts of the flow by c1,2. Computational unpredictability follows from the incapacity of any
numerical model to approximate the real flow over increasing time, because of such exponentiating
divergence. (b) The fern leaf set is an example of a fractal generated by a simple recursive
transformation. (c) Non-integer fractal dimension D of the Koch flake. If we subdivide a line of
dimension 1 into pieces we get 31 units of 1/3 the length . If we have a planar region of dimension 2
there are 32= 9 square sub-units of 1/3 the length. In the Koch flake, each side is repeatedly replaced by
4 = 3log4/log3 sides of length 1/3. Hence its fractal dimension is log4/log3 ~ 1.26.
The Nature of Chaos
Far from being the nemesis of order, or the primal ooze in which order is imposed, chaos is also the
genesis of new form. Most complex systems arise from the mutual interaction between chaos and order,
through bifurcation - ‘abrupt change of form under continuous underlying transformation. Bifurcation
takes its name from ‘forking’ but really applies to all discrete transformation under continuous change. It
is typified by the onset of opposing flight or fight reactions, and sudden transformations, such as a wave
breaking, or a bubble bursting. Bifurcations can introduce new structure and hence increasing
complexity, particularly in transition from chaos to order, in dynamics occurring at the ‘edge of chaos’.
Julia sets (white) of a complex logistic map (see below) are fractal regions on which the process is
chaotic. On the insides (rainbow levels) and outside (rainbow shades) the process is ordered. The
multiple basins inside converge towards attracting periodic points and the basin outside to infinity.
Dynamics in the Julia sets are repelling, scrambled and sensitive to initial conditions, mapping any
neighbourhood of the set over the whole. In every case, the dynamic is divided between complementary
regions of order and chaos.

King, C., The Nature & Sensitivity of Chaos
The failure to appreciate the generative nature of chaos has led to it being one of the last scientific
frontiers to be discovered, over fifty years after relativity and quantum theory. This has happened
because the human will to impose order, even among scientists, is so strong that somehow, in their rush
to fit every phenomenon into a mechanistic world view, they ignored the fact that virtually all
interesting natural phenomena involve chaos, from the waves on the beach, to the beauty of a forest,
from our seemingly regular heartbeat to the patterns of our brain waves in the moment of ‘eureka’!
Mathematicians distinguish dynamical chaos from a random, or stochastic process, in which critical
events are determined by probabilities. Dynamical chaos is not simply disorder or randomness, but an
internally unstable process. Chaotic systems may have well-defined dynamical formulations and may
even be deterministic as classical systems, but this dynamic is one which doesn’t settle down either into
equilibrium or any particular periodicity or resonance, but wanders erratically over time in an
unpredictable way which is deceptively similar to randomness.
Although chaotic systems may be precisely defined by a recursive formula or feedback process, they
combine erratic behavior with long-term unpredictability which gives them just the character those
seeking orderly prediction might fear. Chaotic bifurcations and a closely-related phenomenon called
self-organized criticality are also frequently associated with crises such as cyclones, floods, avalanches,
earthquakes and other catastrophic natural interventions.
The Lorenz butterfly effect: a puff of a butterfly’s wing in a chaotic weather system can inflate into a
tropical cyclone. Weather is thus intrinsically unpredictable, because the small differences in a tiny puff
can grow and throw the whole system wildly off-course.

King, C., The Nature & Sensitivity of Chaos
The essential characteristics or ‘axioms’ of classical chaos are threefold (Devaney R160):
1. Sensitive dependence: Lorenz, the father of chaos theory, was first to note the key characteristic of
chaos in the ‘butterfly effect’, that the eddies of the wings of a butterfly flying in Hawaii could later
become the seed of wild unpredictable fluctuation of a tropical cyclone hitting Fiji. This is ‘sensitive
dependence on initial conditions’, in which arbitrarily small changes can later become amplified by a
chaotic process or flow into global fluctuations.
2. Topological mixing: Any small open region will eventually become mixed over any other. This
means the dynamics is very tangled, so any orbit goes almost everywhere in the ‘phase space’ of
configurations of the system. This is precisely what happens in an egg-beater. This mixing property
sometimes referred to as ergodicity makes the orbits or trajectories of a chaotic process appear random.
3. Dense periodicities: Chaotic dynamics is densely permeated with repelling periodic oscillations, often
of infinitely many types, making for a great deal of hidden complexity.
Another way of encapsulating the latter two properties is to find a dense orbit – single trajectory in the
system which comes arbitrarily close to every point in the space of states. These three combine to mean
the dynamic is complex, unstable and unpredictable.
Sensitive dependence causes chaotic systems to eventually become fundamentally unpredictable even
when they are deterministic. They cannot be accurately computed, since arbitrarily small errors in the
computation rapidly escalate into global inaccuracies. This unpredictability is at the core of the
difficulties of weather prediction and it also lies at the root of diverse phenomena, from the stock
market, to the risk of nuclear holocaust.
Associated with many chaotic systems and some statistical ones such as the ‘drunkards walk’ of
Brownian motion, are beautiful, complex self-replicating patterns called fractals after their properties of
self-similarity on smaller and smaller scales. Fractals are typified by the snowflake, trees, our lungs, the
pattern of forest clearings and the biodiversity we associate with the evolutionary tree of life.

Whirls of water passing a stick (Schwenk R630).
Fractal processes do not have to be geometrically self-similar, but possess a self-replicating basis which
leads to a non-integer dimensionality, hanging paradoxically between the integer values we are
accustomed to. The Mandelbrot set, a portion of which is illustrated below has varying parts
representing all the different ways we can make a feedback by squaring a complex number and adding a
varying constant. The Koch flake fractal above replaces a side of a given length with 4 sides of length
1/3, thus having a dimension of log4/log3.
Chaos occurs throughout nature, from the fractal structures of galactic clusters, through the erratic orbits
of comets to the dynamic many-body energetics of the atomic nucleus. It is manifest in biological
systems from fractal tissues and organs such as the form of our lungs, from the seemingly regular heart
beat, through brain dynamics, to the laser pulse.
Quantum systems modify the nature of chaos, suppressing some of the fine details of the interweaving
of paths in the overlapping of waves possessed by all quanta, which tend to reveal the periodicities
hidden in chaotic systems.

King, C., The Nature & Sensitivity of Chaos
Wave functions, associated with the energy levels of a highly excited hydrogen atom in a strong
magnetic field can exhibit both periodic and chaotic qualities. However the wave aspect smooths and
partially suppresses chaos. The chaotic quantum wave functions are modified from the classical picture
by ‘scarring of the wave function’ paradoxically concentrating the probability around hidden repelling
periodic orbits (Gutzwiller R274).
Nevertheless molecular kinetics is a living example of quantum chaos - a form of unstable wave-particle
billiards which affects all the processes and reactions occurring in our enzyme reactions.
Chaotic systems arise naturally from positive feedback processes because the positive feedback
amplifies small differences, causing the instability we see in the butterfly effect. We shall see shortly
that sexual selection is a potentially chaotic positive feedback process, prone to exponential runaway. In
this respect it is complementary to the stabilizing ordered constraints imposed by natural selection.
Many apparently periodic phenomena are actually chaotic. The heart beat appears periodic, but the
healthy heart is actually tuned by chaos. This allows the brain and heart pacemakers and the heart cells
themselves all to keep in feedback resonance with one another and thus respond to changing
circumstances. No two heartbeats have exactly the same interval between, but vary in a chaotic manner,
similar to a dripping tap.
The universe is fractal in its manifestation in galactic clusters, galaxies, solar systems, stars planets and
satellites and chaotic in its diversity. Some models of cosmic inflation and cosmic evolution are also
fractal, however the supposedly chaotic formless cosmic origin in the ‘big-bang’ is described by
symmetry-breaking of an almost symmetrical or isotropic germinal state, marred only by quantum
fluctuation. Herein may lie the ultimate source of what we experience macroscopically as chaos quantum uncertainty itself. Quantum uncertainty amplified by chaotic instability may be at the heart of
other processes we describe as random, from molecular kinetics to tossing a coin.
Closely associated with chaotic and fractal processes are systems in a state of self-organized criticality.
A sand pile always converges to a limiting angles where fractal avalanches maintain the entire system in
a critically unstable state. Make the pile flatter and it heaps up again. Make it too steep and avalanches
bring it back to criticality. Phenomena such as earthquakes, avalanches and neurons tuned to threshold
excitation, share features of fractal instability. Hence smaller and larger earthquakes occur on a fractal
pattern of frequencies.
Population Catastrophe and the Beauty of Fractals
One of the most serious questions facing humanity is the boom or bust nature of human population
explosion. Will we explode to an unsustainable population and wipe ourselves out with a global famine,
or will we settle down nicely into equilibrium all a bit hungry but survivors as the population settles to a
new plateau? The answer to this question is exceedingly complex and opens out the jewel of complexity
hidden within chaos.

King, C., The Nature & Sensitivity of Chaos
We will illustrate some of the elementary properties of chaos by looking at one of the simplest systems
of all - an iterated feedback in one real variable. It is an archetype of the population explosion dilemma how to feed a naturally growing population from a finite resource without boom and bust destroying the
species.
The quadratic logistic map:
describes seasonal natural population growth given a constrained food supply. The term rxn gives
natural growth by a factor r, while the additional term (1 - xn) limits growth in proportion to the
unconsumed food resource (e.g. the remaining area of arable land). Many possibilities arise, depending
on the growth rate r. As the growth rate varies, the iteration goes through a sequence of different stages
separated by sudden changes, or bifurcations. For small r the system tends to a fixed equilibrium point
then becomes repelling bifurcating to form a flip-flop (period 2), subsequently period doubling to form
periods 4, 8, 16 etc. through to infinity.
The logistic map: (a) As r increases from 2 to 4 the attracting final state is initially a single curve ( an
equilibrium point for each r ) but then it repeatedly subdivides (pitchfork bifurcations) to make a rich
and lean year (period 2) then periods 4, 8 etc., finally entering chaos (stippled bands). Subsequently
there are windows of period 3, 5 etc. with abrupt transitions to and from chaos. The Lyapunov exponent
indicates whether the system is chaotically amplifying small differences. During chaos it remains
positive. The Mandelbrot set illustrates the fractal nature of the ordered and chaotic regimes when x and
r are extended to the complex number plane. (b) A series of 2-D views of the iteration, including periods
1, 2 and 8 chaos, intermittency, and period 3. Pick an initial value x and find y by moving vertically to
the curve y = r x (1 - x). Next we let the new x = y by moving horizontally to the sloping line. The two
steps result in one iteration, i.e. xn+1 = y = r xn (1 - xn). (c) The non-escaping points form a disconnected

repelling fractal for r = 4.5. The attracting final set has now broken up, resulting in a fractal Julia set. (d)

2n square root solutions of the inverse function
.
At this point, a new erratic behaviour emerges, and the system wanders with no fixed period. chaos has
appeared. All of the previous periodic attractors continue to exist hidden in the chaos as repellers,
generating a tangled repelling flow, whose spreading causes sensitive dependence. As r increases
further, windows of order, with new periods appear in a new and abrupt type of transition from chaos to
order. There is yet a third type of chaotic transition represented by the mode-locked periodic feedback,
as in the heart pacemaker and rotations on the periodic spirals of the Mandelbrot set illustrated below.
A portion of the Mandelbrot set of the logistic map. The fractal displays all possible quadratic
dynamics. Although these vary and it is thus not exactly self-similar, it is nevertheless a fractal.
Finally a new situation emerges. The attractor becomes unstable. All that is left is a residual set of
points, which do not escape, but are mapped chaotically among themselves. This Julia set has a
complicated self-similar structure like a fern leaf or a snowflake and is called a fractal. Invariant sets of
chaotic systems in several dimensions are frequently in the form of fractals, characterized by having a
non-integer dimension (Peitgen et. al.R532, R533)
The fractal invariant sets can be seen in far more detail and beauty if the process is extended to the plane
of complex numbers (a + ib where i = -1). The Julia sets now clearly appear as fractals, each with a
differing structure depending on the growth rate parameter.  The Mandelbrot atlas set of all these
dynamical variations has been dubbed the most complicated mathematical structure ever known.

King, C., The Nature & Sensitivity of Chaos
Chaos occurs in a surprising variety of phenomena, many of which appear at the surface to be periodic.
Both the heart beat and the dripping of a tap, although apparently periodic have chaotically intermittent
variations in the beat period. The rings of Saturn and objects still remaining in the asteroid belt are
governed by mode-locking chaos. Only those whose orbital periods have no rational (fractional)
relationship remain, because all the fractionally-related orbits have long ago been thrown into the
planets by a repeated sling-shot effect. When orbits of two astronomical bodies become mode-locked
they interact strongly on a regular basis and the cumulative effect may throw the smaller one out of
orbit. The asteroids remaining today are in a belt where the periods do not mode lock and have thus been
left behind. More generally a large variety of systems from the weather through earthquakes, movement
of the continental plates, chemical and electronic oscillations, secretion of enzymes, fluctuations in the
stock market and collision of successive billiard balls, through to brain waves and possibly cognition
itself, involve chaos or chaotic phases.
Julia set of the complex cosine pervades the plane, evolving firstly through an explosion to fractally fill
the residual black region and then through an infinite set of fractal bifurcations.
Chaos presents us with new properties of nature which are connected with the development of
complexity. A chaotic system contains within it a fractal structure with diverse dynamics, including a
dense set of infinitely many periodicities.

Mode Locking and the Devil’s Staircase
One particularly interesting feature of non-linear interaction manifest in many situations from the
heartbeat to planetary orbits is the phenomenon of mode-locking.
Here coupled periodic phenomena with a periodicity close to a rational number become mode-locked
into a rational relationship. This relationship is illustrated by the devil’s staircase, a fractal function
whose graph is continuous and increasing yet constant in a neighbourhood of every rational number. A
close examination of the Mandelbrot set (p 383) will confirm that the bulbs on the set follow a devil’s
staircase pattern with the two largest bulbs above and below having 1/3 of a revolution (see the three
dendrites) and the large bulb on the left corresponding to 1/2 a revolution, with the rest forming a series
conforming to the devil’s staircase arrangement, in numbers called a Farey Tree. In which any two
fractions generate a descendent by the rule
The Farey tree links all the mode-locked rationals in an infinite net. Starting from the top right if we
alternate left and right we have a sequence of Fibonacci fractions converging to the golden mean. The
Fibonacci numbers 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, ... are generated by a similar relation
Their ratio tends in limit to
, giving
,
the so-called golden mean number, which along with other such extreme irrationals, are the last numbers
to become captured by mode-locked intervals.

Mode-locking explains a vast variety of phenomena. The remaining asteroids all lie in the non-mode
locked regions between Mars and Jupiter because rational orbital periods with respect to Jupiter have
long ago been swept into the sun or planets by the pumping action mode-locking causes. Many
apparently periodic phenomena such as the heart beat are also governed by mode-locking. A simple
circular iteration called the circle map which can generate such behavior by modeling a sinusoidallykicked rotator can be defined as follows:
where
is a constant twist by a fixed angle per iteration and the sine term causes a wobbling or
pumping effect, resulting in an average twisting which may become mode-locked.

(Schuster R628).
A ‘spin glass’ is considered to be a disordered system of spins just as a glass is a disordered quasicrystalline substance. A ferromagnet has lowest energy when all its spins are aligned, giving a stable
polarized lowest energy state. In an anti-ferromagnetic substance each adjacent pair of spins have a
lowest energy state in which they are alternating up and down in a 3-D checkerboard pattern like the
Na+ and Cl- ions in a crystal of salt. Closest spins have the most powerful neighbouring interaction with
the strength falling off e.g. with the square of the distance. When there is no magnetic field the whole
system is thus perfectly regular. However when an external field is applied, it becomes impossible for all
the spins to resolve themselves in a single lowest energy arrangement, and many local minima become
possible like a complex pattern of swamps and small lakes in a wild landscape. As shown on the
previous page, this process is governed by mode-locking, implying that a spin glass contains fractal
islands of partially resolved spins. A similar model may well describe human sexual mating patterns
under a situation where one sex or the other is in scarcer supply.
Multifractality
Many fractal processes, from turbulence to the Julia sets of a quadratic mapping, distribute themselves
unevenly, so that the process becomes fractally concentrated more in some regions than others. One can

envisage this process if we cut an interval in half and give one side probability p and the other
probability 1-p and repeat the process endlessly (see inset).
Top left: Julia set plotted by inverse iteration showing the multifractal distribution of how frequently
differing subregions are visited. Inset fractal application of a probability in three stages. Inset an interval

function representing the information loss describes the multifractal spectrum of probabilities in the
limit. Right: a continental landscape generated by repeated division of a planetary surface (see
Peitgen R532, R533).
There are then fractal subpopulations corresponding to a given probability level, with a spectrum
differing fractal dimensions hidden in the process. Many processes we see in nature are like this. For
example if we divide the surface of the Earth into two broad regions and estimate that 60% of the
population will be on one side and 40% on the other and repeat this process fractally, we will end up
both with very sparse regions like the Sahara and very dense foci of population like New York. A
similar process can generate continents.
The same process occurs with the inner dynamics of a Julia set as shown in the diagram if the iteration is
run backwards to find all the 2n square root solutions n-steps back and so on. Some regions are visited a
very large number of times, while others are visited exponentially rarely. This means it would take
longer than the history of the universe to draw a Julia set if we simply used the raw inverse method as it
stands.

The Edge of Chaos and the Complexity of Nature
“Out of chaos comes order.” Friedrich Nietzsche
A system which can bifurcate between chaos and order over time can enter a mixing phase of chaos and
then retrieve structures hidden within chaos by bifurcating back into order. A chaotic system can
likewise be tuned to display its hidden periodicities. Many types of system develop complex evolving
structures in the transition region between order and chaos, sometimes called the ‘edge of chaos’. The
edge of chaos thus represents the region of sexual paradox between chaos and order where complexity
becomes emergent.
Nature and evolution are both described as complex systems evolving at the edge of chaos. Many of the
most beautiful aspects of nature arise from their fractal structures and textures. Climax forests are
chaotic systems, both in terms of their species diversity and their fluctuating population dynamics.
Climax forest also displays a fractal dynamic which is central to its diversity. Natural disturbances from
fire and flood, wind and storm damage, to large falling trees are fractal disturbances to which diverse
species become adapted in disseminating seed in an ever more complex arrangement of species
diversity. The forest is colonized in up to five strata from the top canopy to the floor each with their own
ecosystemic complexity.
Both plants and animals are derived from fractal algorithms in nature and it is from these fractal
algorithms that most of our understanding of form and diversity in nature comes. Evolution and its
increasing complexity is a central instance of edge-of-chaos dynamics, as is our dynamical brain state, in
both perception and problem-solving, especially when perceiving the chaotic diversity of nature itself
for which we are highly adapted. It is the very sensitive dependence of chaos which ensures the brain
remains completely adaptable to arbitrarily small differences.
The sunflower contains two sets of 34 and 55 spirals left and right enabling seed packing which avoids
any periodic mode-locking. Many animal proportions also reflect the limiting ratio of two such magic
numbers in the golden mean of 1:1.618, illustrating frozen chaos at work (see R556, R624).

An intriguing illustration of frozen chaos permeating biological organisms is the incidence of the golden
mean as a ratio or angle in both animal and plant form. The twin spirals observed in plant forms,
including the pineapple, pine cones, sunflowers and cacti occur at the golden mean angle 2p/g and
generally have two related Fibonacci numbers. This prevents any ordered pattern of mode-locking
which would prevent the seeds of the sunflower packing together properly.
Similarly many human proportions, from successive digit bones, the relative distance from the navel to
the head and feet, the widths of successive incisors and the nose, mouth and eyes all conform to the
golden mean. This is the last, most irrational number to submit to mode locking, as do the orbits of the
remaining asteroids in relation to the orbit of Jupiter. Mode locking can also bee seen in the 13 arms of
the Mandelbrot portion above, where the dynamic is making 1/13 of a revolution.
The lynx is a species with regularly, yet erratically oscillating numbers. It was once believed that lynxes
were partners in a dynamically unstable association with their main prey, the snowshoe hare. Recently it

the lynxes being carried along more or less passively by changes in the abundance of hares
(Leakey R316).
In addition to this, the potentially chaotic population dynamics we have seen in the logistic function is
displayed in many natural populations making population dynamics unstable from season to season and
sensitively dependent on changes in the environment. For this reason, we have to be very careful when
considering the major impacts we are making on natural ecosystems, lest chaos and bifurcation
compound the problems we initiate.
It is important to note that population dynamics may cause paradoxical situations to arise. For example
we usually think of a predator-prey relationship as exploitative. However a predator acts to reduce the
growth rate of a population and thus protects it from boom and bust population crisis in which the prey
multiplies so fast that it eats all the available food and dies en masse through starvation. Thus predator
and prey are caught in a kind of prisoners dilemma relationship which is both destructive and protective
at the same time.
Similar considerations apply to parasites and hosts. A central development of this dynamical relationship
we shall see next is the idea that a prisoners dilemma genetic ‘arms race’ between parasites and hosts led
to sexual evolution to promote genetic variety and hence resistance to disease. This mutual adaption
arms race thus required each of the competing organisms to become capable of sexual recombination to
survive the others changes.
Once sexuality became established, sexual selection began to become a fundamental driving force
complementary to natural selection. Because natural selection tends to operate as environmental or interspecies constraints on survival it is both stable and predominantly a negative feedback. In addition the
vast majority of mutations are deleterious.

King, C., The Nature & Sensitivity of Chaos
The peacock’s tail illustrates how sexual selection can become a runaway positive feedback process,
leading to chaotic unpredictability. Once again we see hints of Fibonacci golden mean spirals.
Sexual selection has very different characteristics from natural selection. Firstly it acts not negatively on
survival but positively on reproduction. It is also an iterative feedback process with strong positive
feedback characteristics. Female reproductive choice acts as a capricious and variable positive feedback
which, as it adapts to competing display by becoming more discerning, drives male evolution into
potential runaway. Mutual mate selection can also have powerful effects. This leads to sexual selection
becoming a potentially chaotic positive feedback force complementing the stabilizing effects of natural
selection. These effects are again complemented by the opposing effects of mutations and recombination
as genetic modifiers held in check by selection retaining only the viable options.
These effects result in a deep connection between sexual paradox and edge of chaos complexity.
Broadly speaking the condition of sexual paradox induces sensitively unstable dynamics which lead to
complex systems dynamics at the edge of chaos because the actions of each of the partially opposing
forces are frustrated from imposing order. Loss of sexual paradox leads to degeneracy, with a dominant
stable process and consequently reduced complexity and reduced viability. Thus maintaining sexual
paradox in evolution and climax diversity in planetary abundance and resilience go hand in hand.
Although our gatherer-hunter origins appear to be sexually paradoxical, many aspects of human culture
show loss of sexual paradox into degeneracies of patriarchal sexual and natural dominion involving
boom and bust and rape of the planet’s diversity. These are accompanied by very worrying instances of
loss of complexity which need urgent correction to ensure human viability.
Strange attractors in brain dynamics Freeman (R226)
A final example of the interdependence of chaos and order in the development of complexity is
illustrated in the brain, (p 323), which is not simply a digital computer but displays prominent dynamical
behavior, illustrated in the broad spectrum waves of excitation in the electroencephalogram. This
excitation is distributed across the cortex in a manner consistent with parallel distributed processing.
Both perception and cognition can be modeled as a transition from a state of chaos representing the
unrecognized condition, or the unsolved problem, to a state of order. This process can be modeled as a
transition: from high energy chaos, ‘exploring’ its internal space without getting stuck in any ‘rut’; to
order, as the energy is reduced so as to flow towards a minimum, through the capture of the system by a
learned attractor in recognition, or the bifurcation of the system to form a new attractor. An insight

‘eureka’ often happens instantaneously, from a state of relative confusion, indicating a single transition
from chaos to new order representing the ‘knowing’ state. The chaotic state is thus the progenitor of
new order, rather than mere manipulation of order itself. Rather the order imposed by the problem
becomes a boundary condition for chaotic resolution.
Cellular Automata and Chaos
A series of 1-dimensional cellular automata with l varying from order (0.23) through complexity at the
edge of chaos (0.33) to deep chaos (0.86). All complex states in 3 eventually expire, but not in 4.
Several of these attributes of order, chaos and complexity can be displayed in some the simplest digital
feedback processes, of all called cellular automata (see Wolfram R606). These contain a formula
expressing the successive states in a grid of cells in terms of their immediate neighbours. Depending on
the nature of the formula, and the degree of overlap, such systems can be defined to involve ordered
equilibrium and periodicity, chaotic mixing of states, or complexity. Systems close to the edge between
order and chaos display the capacity for increasing complexity.
For example if we consider the simplest 1-dimensional cellular automaton which has only values 0 and 1
in a given cell and determines the new state of any cell from the three immediate predecessors in the
preceeding row, we can define a unique rule as a number.
There are 23=8 different arrangements of a cells three immediate predecessors. To specify the rule we
thus need to specify a 0 or 1 in each position giving 28 = rules numbering 0 to 255.
Rule 110, for example, displays edge-of-chaos complexity. This system is even capable of functioning
as a universal computer, because various sub-states can exchange information and perform the
fundamental computations of symbolic logic.

King, C., The Nature & Sensitivity of Chaos
Rule 30 displays the key features of chaos in digital form. The eventual states are sensitively dependent
on the initial conditions. If we put a Cantor topology on the space of configurations, we find periodic
solutions are dense (the is a finite configuration with any finite pattern of cells) and any two states
become mixed in the sense that a configuration containing one pattern leads to one containing the other.
Finally there is a dense orbit, a configuration that eventually displays any given finite pattern of cells.
A famous example of complexity with universal computation is Conway’s ‘game of life’ in which a
given cell survives if two or three neighbours out of the possible eight are alive and is ‘born’ if precisely
three are alive. The ‘game of life’ behaves in a similar manner to a complex dynamical system at the
edge of chaos. Here successive states show increasing complexity, including drifters capable of logical
computation. Such processes, including 2-D cellular automata simulations of the prisoners’ dilemma,
(p 21), may thus become formally undecidable because of the Turing halting problem (p 351). Conway’s
game of life is equivalent to a prisoners’ dilemma game where cooperation is incited by three
cooperating neighbours and the status quo maintained by two, with other values leading to defection.
A sequence of states in the game of life
Below are illustrated some variants of the game of life in which a variety of slightly higher rewards are
given for cooperation, leading to permanent equilibrium between cooperators and defectors similar to
the results of Nowak’s more detailed simulations, (p 21) but using only simple rules of the same
type as Conway’s.
Unlike the game of life, consciousness is not bound to a discrete classical logic. Ultimately, through
chaotic sensitivity, the conscious brain may be able to access the quantum realm and putative forms of
quantum computing and transactional space-time hand-shaking, manifestations of the weird properties
of uncertainty, non-locality and entanglement, arising from quantum complementarity between wave
and particle aspects. Consciousness appears to use these deeper complementarities within quantum
chaos to anticipate potentially incomputable complexities and to affect physical outcomes through the
application of conscious will. Here we come to the deepest expression of that complementarity in logical
and existential paradox of which chaos and order are also a reflection. This is where sexual paradox
enters its quintessence.

2-D cellular automaton variants of the game of life. If Conway’s game is represented as 001300000
meaning death for 0, 1 and 4-8 live neighbours, the status quo for 2 and birth for 3. From top left (a)
001330000 showing long-term equilibrium between defectors (yellow and orange) and cooperators
(black and blue). (b) Symmetrical fractal states generated by a single defection for 001300001- very
close to the game of life - giving an expanding regime of computational unpredictability for the
continuity of life (cooperation) amid defection (death), similar to Conway’s game. (c) 301300001, (d)
301330001 and (e) 331300001, in which rare cooperators are rewarded.
