There are times when the only thing to do is to wait. The seed has been planted, the child is growing in the womb, the oyster is coating the grain of sand and making it into a pearl. This card reminds us that now is a time when all that is required is to be simply alert, patient, waiting. The woman pictured here is in just such an attitude. Contented, with no trace of anxiety, she is simply waiting. Through all the phases of the moon passing overhead she remains patient, so in tune with the rhythms of the moon that she has almost become one with it. She knows it is a time to be passive, letting nature take its course. But she is neither sleepy nor indifferent; she knows it is time to be ready for something momentous. It is a time full of mystery, like the hours just before the dawn. It is a time when the only thing to do is to wait. We have forgotten how to wait; it is almost an abandoned space. And it is our greatest treasure to be able to wait for the right moment. The whole existence waits for the right moment. Even trees know it--when it is time to bring the flowers and when it is time to let go of all the leaves and stand naked against the sky. They are still beautiful in that nakedness, waiting for the new foliage with a great trust that the old has gone, and the new will soon be coming, and the new leaves will start growing. We have forgotten to wait, we want everything in a hurry. It is a great loss to humanity.... In silence and waiting something inside you goes on growing--your authentic being. And one day it jumps and becomes a flame, and your whole personality is shattered; you are a new man. And this new man knows what ceremony is, this new man knows life's eternal juices.

One of the fields of complexity where most has been concentrated the research is the neurophysiology of the vision system, that is how and what we see.
Anatomically and physiologically the brain visual system is widely known:
The image formed on the eye retina and codified is transferred by the optic nerve in the lateral geniculate nucleus (NGL/LGN), situated in the thalamus, from where nerve pathways go toward the visual cortex (CV/VC), the brain area which specific elaborate the information coming from the optic nerve. In particuar images from the right eye are elaborated in the left visual cortex, and vice versa.
The visual information flow according to this anatomical-functional model is represented as:
Following this model some thousands (litteraly) of works and papers has been made. The direct consequence of a model of this kind is the representationalist approachto the brain, outlined by Maturana and Varela with the Caesar's figure looking at the Imperial Eagle:
In the Varela words:
"The Caesar's Eagle is represented in his brain through the activity flow (the film tape) cthat undergoes a "treatment" (by some small operator) and which later produces the behavioral proof of the recognition by the word "eagle" (through carefully selected organ pipes)"
A model of this type is also what normally assumed by common sense: an object outise ourselves is represented in some way inside our head; more technically an object in the visual field are associated specific neural activity patternsi, typically in the primary visual cortex. The ultimate consequence is when we imagine ourselves, where the imagined ourselves naturally imagines himself, and so on, as in the following illustration by Von Foester, an extreme solipsism case:
where have been added those connections to the NGL which do not come only from the retina but also from other central areas of the brain, including the same visual cortex. The conclusion is that less then 20% of the information dell'informazione which get the geniculate body come from the retina. The situation, drom the point of view of a neuron in the geniculate body, is more similar to a cocktail party rather than to a linear element of an information chain forwarded from the retina to the visual cortex. In addition, the dashed arrows may be bidirectional for the information, for example the visual cortex receives information from the geniculate body but at the same time forwards other information to the geniculate body. The Varela conclusion is:
"... in the visual system ... does not exists an overall flux, the system is organized in a reticular pattern, and there is a simultaneous convergence or coherence among all the parts concerned."

Logic can often be reversed, but the effect does not precede the cause. This generalization has been a stumbling block for the psychological and biological sciences since the times of Plato and Aristotle. The Greeks were inclined to believe in what were later called final causes. They believed that the pattern generated at the end of a sequence of events could be regarded as in some way causal of the pathway followed by that sequence. This led to the whole of teleology, as it was called (telos meaning the end or purpose of a sequence).
The problem with confronted biological thinkers was the problem of adaptation. It appeared that a crab had claws in order to hold things. The difficulty was always in arguing backward from the purpose of claws to the causation of the development of claws. For a long time, it was considered heretical in biology to believe that claws were there because they were useful. This belief contained the teleological fallacy, an inversion of causality in time.
Lineal thinking will always generate either the teleological fallacy (that end determines process) or the myth of some supernatural controlling agency.
What is the case is that when causal systems become circular, a change in any part of the circle can be regarded as cause for change at a later time in any variable anywhere in the circle. It thus appears that a rise in the temperature of the room can be regarded as the cause of the change in the switch of the thermostat and, alternatively, that the action of the thermostat can be regarded as controlling the temperature of the room.
A second model for complexity at level 1 - chemical - has been developed by Ilya Prigogine on the thermodynamic of complex susystems far from equilibrium, particolarly on the so-called dissipative systems, to be understood as an thermodynamical open system which works in a state far from thermodynamical equilibrium, exchanging energy, matter and/or entropy with the environment. Dissipative systems are characterized by spontaneous formation of anisotropy, namely of complex and oredered patterns, sometimes chaotic. Sush sustems, when crossed by increasing flows of energy and matter, may also evolve, passing from instability phases and increasing the complexity of the structure (that is the order) and decreasing their entropy (negentropy).
The term dissipative system has been named by Prigogine at the end of the '60s, lwork for which he received the1977 Nobel prize for chemistry. The contribution of Prigogine was that to bring attention toward the connection between order and energy dissipation, differently from the static and equilibrium situations generally studied until then, and contributing significantly to the birth of what today is called epistemology of complexity.
In recent years there has been developed a vocabulary of complexity with fterms like fluctuation, stability, phase transitions. All these terms refer to the problem of time, which was one of the problems studied since the beginning of Western civilization.
The existence of a physical time separated by a philosophical time was a central issue for the concerns of many philosophers from Aristotle to Heidegger. The latter poses the question: what is time? He answered this question by saying that the time is difference, motion, it is a representation of the difference between what comes before and what comes after. This analysis was taken further by Heiddegger which defines a very strong difference between past and future. He emphasizes that it is not time as introduced by physicists to determine the difference. This explains the fact that science is not able to reach the essence in describing the universe.
Prigogine thinks that all the developments of science in the last decade have shown that time is an essential element of the physical universe. The fact that one is forced to speak of an evolving universe, because it is the only way to describe the events that are observed, is an evidence that the direction of time is not a creation of man but is inherent nature. That's why it is no longer possible to make a distinction between physical time and philosophical time.
According to Prigogine classical physics wanted to eliminate any reference to the history, the history was conceived as something that exists only because we do not understand the causes of a physical process. The universe, however, can not be attributed to independent events, it is not so simple. We also need stochastic events (probability, random, we need to reversibility. We need random events.
Prigogine claims a new scientific logic. On the basis of his view there is distrust on the classical idea that nature always follows the simplest way.
On the contrary, he argues that the operation of the machine-nature is due to the complexity of the irreversible processes. Prigogine comes to this idea analyzing the thermodynamical phenomenon known as entropy. In thermodynamics, entropy is a state function that is introduced with the second law of thermodynamics and which is interpreted as a measure of disorder of a physical system or the universe in general. According to this definition one can say, in a non-rigorous but explanatory form, that when a system moves from an ordered state to a disordered state its entropy increases.
In the historical evolution of the universe, there is indeed an exceptional event that denies the gradual transfer of energy from order to disorder (entropy. This event was the emergence of life on earth and the consequent existence of various forms of life characterized, like other irreversible processes, by self-organization. This latter is against the alleged balance of the natural order and thus against the anti-scientific idea of the simplicity of the phenomena, which should be contrasted with the complexity, that is necessarily the absence of energy balance (entropy) and physical disorder. It then develops the non-equilibrium physics with an underlying nonlinear dynamics. The most unexpected result of this is the awareness of the constructive role of non-equilibrium: far from equilibrium coherent states and complex structures are created that could not exist in a reversible world.
In this way, nature creates dissipative systems like living beings.
ILYA PRIGOGINE: THE EXPLORATION OF COMPLEXITY
“The fact that during growth living organisms actually show a decrease of entropy production during evolution up to the stationary state … also, the fact that their organization generally increases during this evolution [which] corresponds to the decrease of entropy as studied [leads one to puzzle as to why] the behavior of living organisms has always seemed so strange from the point of view of classical thermodynamics; that the applicability of thermodynamics to such systems has often been questioned. One may say that from the point of view of the thermodynamics of open and stationary systems [nonequilibrium thermodynamics] a much better understanding of their principal features is obtained.”

The coordinated movements of liquids and gases leading to patterns can also be observed in the laboratory This figure shows a hexagonal pattern of liquid helium in a vessel that is heated from below. This classical experiment was first done by Bénard (1900) with oil. In the middle of each cell, the liquid rises, cools down at the upper surface and then sinks down at its border

Summary
Fundamental conceptual problems that arise from the macroscopic and microscopic aspects of the second law of thermodynamics are considered. It is shown that nonequilibrium may become a source of order and that irreversible processes may lead to a new type of dynamic states of matter called "dissipative structures."
The thermodynamic theory of such structures is outlined. A microscopic definition of irreversible processes is given, and a transformation theory is developed that allows one to introduce nonunitary equations of motion that explicitly display irreversibility and approach to thermodynamic equilibrium. The work of the group at the University of Brussels in these fields is briefly reviewed. In this new development of theoretical chemistry and physics, it is likely that thermodynamic concepts will play an everincreasing role.
The name that can be named
is not the eternal Name.
The unnamable is the eternally real.
Naming is the origin
of all particular things.
Free from desire,
you realize the mystery.
Caught in desire,
you see only the manifestations.
Yet mystery and manifestations
arise from the same source.
This source is called darkness.
Darkness within darkness.
The gateway to all understanding.
