Organizing Reflections

Organizing reflection 32

This is a post in my series on organizing ”between and beyond.” Other posts are here. The purpose of this post is to reflect on subjects occupying my mind. I make no claim to fully believe what I write. Neither do I pretend that others have not already thought or written about the same subject. More often than not, I take up, combine, and add to already existing thoughts and ideas.

What is on my mind?
Today’s reflection is based on Abeba Birhane‘s (@Abebab) tweets from Alicia Juarrero‘s book Dynamics in Action: Intentional Behavior as a Complex System. This is an interesting book about complexity and human intentionality. Juarrero argues that a mistaken model underlies contemporary theories of action and proposes a different logic based on complex adaptive systems.

With thanks to Abeba Birhane, here are some quotes from Alicia Jarreror’s book (my highlights in bold):

Behaviourist analyses have tried to reduce the flexibility and appropriateness characteristic of human action to stimulus-response patterns.

What went largely unrecognized until recently was the fact that the classical thermodynamics of the 19th century treats all systems as if they are closed, isolated & near equilibrium – which living things are not.

Interactions among certain dynamical processes can create a systems-level organization with new properties that are not the simple sum of the components that constitute the higher level.

The causal mechanism at work between levels of hierarchical organizations can be best understood as the operations of constraints.

When organized into a complex, integral whole, parts become correlated as a function of context-dependent constraints imposed on them by the newly organized system in which they are now embedded.

Constraints work by modifying either a system’s phase space or the probability distribution of events and movements within that space.

There is ample evidence that the human brain is a self-organized, complex adaptive system that encodes stimuli with context-sensitive constraints.

Far from representing messy, noisy complications that can be safely ignored, time and context are as central to the identity and behaviour of dynamic processes as they are to human beings.

Unlike the processes described by classical thermodynamics, which in their relentless march toward equilibrium forget their past, complex adaptive systems are essentially historical.

If human beings and their behaviour are complex adaptive phenomena, the precise pathway that their actions will take is simply unpredictable.

Historical, interpretive stories might not allow us to predict future behaviour, but they do allow us to understand why it is unpredictable.

Even after the advent of the theories of evolution and thermodynamics, modern science continued to restrict itself to closed linear systems abstracted from their historical and spatial context.

Only with the recent development of complexity theory have openness, nonlinearity, time, and context come to the forefront.

… philosophers are unable to conceptualize and explain either voluntary self-motion or an agent’s purposive actions. As is often the case in philosophy, it all goes back to Aristotle.

How the Modern Understanding of Cause Came to Be

In a universe where only point masses and forces are considered real, qualities that are a function of the relation between atoms, or between organisms and the world, were dismissed as subjective.

By the end of the 17th century, all relational properties, such as temperature and colour, that did not fit into this scheme were relegated to the inferior status of “secondary” qualities.

Galileo’s ability to set aside the interference of friction from the equations governing the motion of bodies also suggested that context contributes nothing to reality.

Newtonian atomism reduced the universe to the relations between single material points whose movements from one position to another are time-reversible.

True self-cause would involve localized parts interacting so as to produce wholes that in turn, as distributed wholes, could influence their components: interlevel causality between parts and wholes. …

… But by following Aristotle in rejecting this possibility, philosophy closed off any avenue for explaining action in that fashion.

Whether in dualist or materialist guise, and suitably identified as an intention, volition, want-and-belief complex, and the like, cause of action, following Aristotle, have been assumed to be events entirely inside the agent but other than the behaviour itself.

A worldview with a strobelike understanding of time (as well as a gunshot view of cause) has no way of determining when “now” ends and “then” begins.

A theory claiming that action is behaviour caused in a particular manner requires a concept of cause that not only triggers but also structures and sustains behaviour in an ongoing fashion. But none is forthcoming in contemporary philosophy.

Action theory uncritically adopted the standard billiard ball model of Newtonian science: one particle bumps into a second, which it activates even as it disengages.

There is a much closer connection between whatever originates action and the action itself than between billiard balls.

That closeness serves as the ground for appropriateness of certain behaviour given an agent’s reasons or intentions. The closeness is reflected in the description of an intention as the intention-to-do-x.

But advocates of traditional causal relations balked at all this talk because it appears to violate the required separation between cause and effect, a dogma that remains unquestioned, as does the dogma that all cause is efficient cause.

If practical reasoning is unavoidably temporal and contextual, deduction from abstract universals, or even inference from probabilistic laws, is out of the question either as a way of predicting what action someone will perform next or of explaining what he or she did.

Renaissance thinkers like Montaigne acknowledged that universal, foundational principles cannot be applied to such practical matters as law, medicine and ethics; the role that context and history play in those areas prevents it.

How explaining an event came to be identified with predicting it and with that the separation of the hard and soft sciences.

To claim that certain social, empirically determinable conditions, followed by a certain behavior, constitute action is plausible only on the condition that the agent is aware of the meaningful import of the situation [point made via a fascinating little story].

Action is lawful, and the laws to which it conforms refer to social patterns, standards, and conventions. Our explanations and predictions presuppose this.

A rule-following model of explanation is therefore unlike a mechanical model. Behavior can be explained as action only if set in the context of socially delineated means-ends conventions.

The problem of action is not only a problem of explanation; it is primarily an ontological matter. It is not a matter just of how or why we come to see behavior as action; it is a matter of what makes some behavior action.

Goal directedness is not a generalized tending toward an end state.

There is no tidy, linear pairing of causes and effects in human action as there is in the realm of classical mechanics. Despite conditions a, h, and c, people inevitably surprise us by doing the unexpected – not the expected x, y, or z.

Whenever circumstances a, h, and c exist, behavior x, y, and z will be performed, unless 1, 2, 3, . . ., n, with every “unless” qualification that counterfactually affects the entailment fully spelled out.

However, since human beings are complex dynamical systems, this is a hopeless dream.

Behaviorist theories attempted, unsuccessfully, to reduce the appropriateness and fittingness characteristic of action to various stimulus-response patterns, including plasticity around a goal object.

Act-tokens must be explained by referring to the agent’s purposes and ends, and, to the appropriateness of the behavior given those purposes and ends. …

This directed flow of events contrasts with the in-principle reversibility of Hume and Newton’s accounts of causality, according to which it is possible for any sequence of events to go backward as well as forward. …

In mechanics, event a could be followed by event b as well as vice versa. According to Hume, since one experiences no necessitating, directed force between two events, their order, too, is also in principle reversible. …

In the case of action, on the other hand, the very concepts of intention, disposition, agents, reasons, and the like have a built-in one-wayness: they imply that these concepts issue in behavior, not vice versa. Not all one way behavior is purposive, to be sure.

Pendula tend toward a resting state, and avalanches persist in reaching the valley; but although both phenomena exhibit plasticity and persistence toward an end, neither pendula nor avalanches have goals.

Although philosophers today would look askance on an appeal to final causes, any acceptable theory of action must still satisfactorily account for this apparently directed flow of information or meaning from cognitive source to behavioral terminus.

We do not appeal to mental states to explain the incredible complexity of behavioral patterns that one has (antecedently) recognized. …

On the contrary, we come to believe that there is a “complexity” to be resolved in the behavioral manifestations because we already suspect that there is (or might be) a difference in the agent’s motivation, that is, in the agent’s mental life.

Behaviorist accounts [of action] attempted to reduce intelligent action to persistent yet plastic behavioral patterns. In analyzing away the concept of goalhood, behaviorists tried to bypass such ghostly and private notions as having a goal, awareness, and intention.

One positive contribution of behaviorism that is rarely remarked on: behaviorism resuscitated the role that the environment plays in action.

Contextual embeddedness had been an important component in Aristotle’s understanding of action, but was discarded by modern philosophy’s emphasis on primary qualities as the only reality.

By suggesting that behavior is somehow connected to and dependent on events in the environment, behaviorism clearly emphasized the role that context plays in the life of organisms.

… But bringing context back into the picture as behaviorists attempted requires a type of cause much different from the collision-like trigger of mechanics.

Lacking such an understanding of cause, and reinforced in their Aristotelian conviction that causes are external to their effects, logical behaviorists never quite embedded the agent in the environment to create an integral organism-context system.

They just plunked the organism in the environment and assumed that when the appropriate stimulus occurred, boom! the organism would automatically respond.

With the Humean view of explanation as deduction firmly entrenched, “if not predictable not explained ” remains the reigning standard to which all disciplines aspire.

Several decades after the heyday of behaviorism but with no strict covering law (not even a probabilistic one) capturing regularities between empirical circumstances & human behavior on the horizon, the conclusion appeared inescapable: “Human behavior is inexplicable.”

But recent research in nonlinear dynamical systems suggests, on the contrary, that if organisms are more like tornadoes or even “chaotic” systems than like glass or planets, behaviorism’s ideal was doomed from the start.

… The reason is that in open systems that exchange matter and energy with their environment, feedback embeds them in that environment in such a way that they are simultaneously context-dependent and initiators of behavior. As a result, their trajectories are unique.

Basic assumptions on which the modern scientific worldview was based came under attack over time. In the nineteenth century alone, two challenges appeared to that conceptual framework: thermodynamics and evolutionary theory.

Thermodynamic systems can use energy only when “the arrangement of energy is to some extent ‘orderly’: higher temperature here, lower temperature there, and a clearly marked contrast between the two”.

The first law of thermodynamics states that the total amount of energy in the universe is conserved. The second states that, over time, the disorderly arrangement of energy, entropy, inexorably increases, and the orderly, usable arrangement of energy decreases.

… energy potential, that is, by the uniformization of the universe’s arrangement of energy. This equilibrium state constitutes the heat death of the universe.

The inexorable increase of unusable energy (entropy) postulated by classical thermodynamics provided a criterion for differentiating past from present and future.

Measuring the change in the amount of entropy tells you the sequence in which events happen: the state with less entropy comes first, the one with more entropy next, the one with total entropy last.

In contrast to Newtons time-neutral equations, thermodynamics therefore appeared to return irreversibility and temporal direction to science, vindicating the intuition that whereas you can go from an egg to an omelette, the reverse is impossible.

In the end, thermodynamics teaches, you can’t put Humpty back together again.

However, as Boltzmann (1877) argued that the one-wayness pertains only to macroscopic, statistically averaged-out systems; at the atomic level events remain neatly, time reversibly Newtonian.

The arrow of time thus applies only to the law of large numbers; at the microscopic atomic level, ultimate reality remains properly timeless.

The specific location and circumstances from which a system started out, and the particular path it has traversed to date, are irrelevant; whatever its origin, the system will eventually reach equilibrium.

Thermodynamic systems near equilibrium are therefore insensitive to initial conditions. Their past does not affect either their present or their future.

Both classical mechanics and thermodynamics, however, agreed on the deterministic and “machinelike” quality of the universe; they disagreed only on whether motions are reversible.

19th-c thermodynamics deals only with systems as if they were closed and isolated from their environmental context ignoring the relational, secondary qualities – properties that appear in virtue of an object’s interactions with its surroundings and its past.

In a blow to Plato, not to mention religious fundamentalism, Darwin undermined the idea that essences exist that universally and eternally mark off this kind of organism from that. Natural kinds are not eternal; species evolve over time.

Darwin’s writings returned context to science for the first time in centuries. The specific ecological niche in which an organism is embedded matters greatly, since it determines which organisms live and get to reproduce and which do not.

Because organisms are more or less fit relative to the particular environmental niche in which they are located, fitness is therefore a relational property, not a primary one like mass.

And yet much of the flavor of Newtonian mechanics continued to permeate the theory of evolution (Depew and Weber 1995), particularly in the way Darwin understood explanation.

The radical change from Aristotle to Darwin was the recognition that, through the environment’s selective pressure on reproductive success, unpredictable, truly novel phenotypic features could be passed on to future generation.

Open systems far from equilibrium show a reduction in local or internal entropy; they are able, in other words, to create form and order.

General systems theory was first articulated by organismic biologist Ludwig von Bertalanffy (1981) as a counterpoint to classical science’s mechanistic understanding of human beings and nature.

[General systems theory]’s fundamental claim is that when living things are embedded in a orderly context, properties emerge that are not present when the things exist as isolated individuals.

Picking up where Darwin left off, systems theory continued the revival of relational or secondary properties by reminding us that context matters. But it does so very differently than behaviorism.

Together, the internal and external structure constitute the system’s total structure. A system with no external structure – no environment with which it interacts – is a closed and isolated system. Only the entire universe is closed and isolated.

A system’s functional efficiency is often related to its integration. The system is called stable if it returns to or fluctuates minimally around a constant value.

For the most part, the more flexible the coupling between the subsystems, the greater the overall system’s stability.

Resilience is “the ability of the system to absorb changes … and still persist” (Holling 1976). A system can be quite resilient yet unstable if it persists as that (kind of) system despite wide fluctuations.

Resilient systems are able to modify their specific structure so as to ensure the adaptability and survival of their overall organization. Insects and viruses are remarkably resilient: they can mutate dramatically and so persist.

Complex systems are usually more resilient than simple ones, with complex open systems that interact with their environment exhibiting the highest degree of resilience.

As anyone who has tried to rid his house of cockroaches can confirm, evolution generally favors resilience, not stability.

Because their organization is given “from the outside,” machines are allopoietic. Living organisms, on the other hand, self-assemble, and as such are examples of autopoietic (self-organizing) systems.

Allopoiesis versus Autopoiesis:

Thermostats do not self-organize.

No closed system near equilibrium ever becomes more complex or ordered.

But even crystallization is an order-producing process. And living things, unlike crystals, are not “frozen accidents.” They are dynamical, adaptive, and evolving beings that interact with their environment through exchanges of matter and energy.

As we climb the developmental & phylogenetic ladders, organisms grow & species become increasingly complex, one mark of which is their ability to access a greater variety of states and behaviors. People can blink but amoebas can’t; grown-ups can wink but newborns can’t.

The human sciences have often been tempted to model their subject matter after the (idealized) linear, closed systems near equilibrium that the hard sciences studied and that, for those very reasons, were tractable and in consequence produced spectacular results.

I take it as self-evident today that human beings are neither linear, closed, nor near equilibrium, nor likely to be understood by models with these assumptions.

People are neither isolated from their surroundings nor simply dropped into an environment that pushes them hither and yon. On the contrary, they are embedded in their environment, which they in turn influence.

Self-organizing systems that reorganize by altering their control parameters themselves are truly autopoietic.

In virtue of its own internal dynamics, self-organization spawns even higher levels of self-organization and the system as a whole evolves.

A system emerges when previously uncorrelated particles or processes suddenly become coordinated and interconnected.

The conceptual framework of the theory of self-organizing dynamical systems has significant implications for the philosophical concepts of identity, teleology, cause, and explanation.

… after the phase change one finds an orderly arrangement of particles or processes: a system.

Because each of the processes that define an autopoietic system requires the others, the system must be studied as a whole, as the coordination of several process, that is, as a network of activity and relationships.

Isolating each of the processes and attempting to reduce the whole to its components (as atomism tried to do) produces “nothing more than that: a series of snapshots”.

As a dynamic system, therefore, an autopoietic system’s identity is given by the coordinated organization of the processes that make it up, not the primary material of its components.

The system as a whole, to repeat, is not just a passive pass-through for energy exchanges.

A component that may be fit in one context may not be in another; a structure that may be fit in one context or at one time may not be in another.

Far from being a primary quality, therefore, fitness is a multiply realizable property (Depew and Weber) that depends on what occurs elsewhere and previously.

To maintain itself as itself, an autocatalytic web functions as an “attractor”: a rudimentary precursor of final cause.

… It would be anthropomorphic to call this vectorial characteristic of autocatalytic structures “goal-intended” or “purposive”; it would be even more absurd to say that these dissipative structures act as they do “for a reason.”

The dynamic interaction between self-organizing systems and the contingencies of their environment, on the other hand, allows us to understand how both individuation and true evolution (not just development) are possible.

Insect colonies are an example self-organizing systems whose complexity “permits the division of functions, particularly the division of labor, as well as hierarchical relationships and mechanisms of population control” (Jantsch).

The evolutionary advantage of such systematic hierarchical differentiation is that the whole can access states that the independent parts cannot. The overall hive can do much more than the individual bee. The price is that workers in a hive lose the ability to reproduce

Dissipative structures thus operate on two levels simultaneously: part and whole, which interact in the manner of Douglas Hofstadter’s “strange loops,” or Kant’s “unknown causality.” In Chuck Dyke’s great phrase, they arestructured structuring structures.”

… concrete things over processes and relations, substances over properties.

Complex adaptive systems exhibit true self-cause: parts interact to produce novel, emergent wholes; in turn, these distributed wholes as wholes regulate and constrain the parts that make them up.

According to nonlinear, far-from equilibrium science (and without appealing to any mysterious elan vital), systems are created from interacting components, which they then, in turn, control.

As a result of this strange loop relationship between parts and wholes, these dynamical systems are not mere epiphenomena; they actively exercise causal power over their components.

Dissipative structures are not mechanical processes; in autocatalysis no one molecule pushes the others around. Neither does anyone of the brain’s neurons.

The central nervous system has no localized grandmother control unit that, in the manner of a Newtonian force, activates others by bumping into them.

The concept of constraint was first used formally in physical mechanics to describe the way the motion of a simple pendulum or a particle on an inclined plane is “compelled by the “geometry of its environment to move on some specified curve or surface”.

Constraints are relational properties that parts acquire in virtue of being unified – not just aggregated – into a systematic whole.

Limiting or closing off alternatives is the most common understanding of the term “constraint.” But if all constraints restricted a thing’s degrees of freedom in this way, organisms (whether phylogenetically or developmentally) would progressively do less and less.

… However, precisely the opposite is empirically observed. Some constraints must therefore not only reduce the number of alternatives: they must simultaneously create new possibilities.

According to information theory constraints are identified not as in physical mechanics, with physical connections, but with rules for reducing randomness in order to minimize noise and equivocation.

In a situation of complete randomness where alternatives are equiprobable you could say anything but in fact do say nothing. It is true that in situations in which all alternatives are equally likely, potential information or message variety is at its maximum.

At equilibrium, message variety is a great but idle potential; actual information is zero. “Capacity is of no value if it cannot be utilized ” (Gatlin 1972).

Without contrasts there can be no message; television snow is as meaningless as white noise. Transmitting or receiving a message requires a clear demarcation between message and background noise.

Whether in communications or genetics, actual information content – a difference that makes a difference – requires an ordering process that harnesses the randomness.

Constraints turn the amorphous potential into the definite actual: following Aristotle, constraints effect change.

Constraints alter the probability distribution of the available alternatives. They make a system diverge from chance, randomness, or equiprobability. Lila Gatlin calls constraints that function in this manner context – free.

Once the probability that something will happen depends on and is altered by the presence of something else, the two have become systematically and therefore internally related.

Because dissipative structures are not just dropped into either time or space the way Newtonian atoms with only primary qualities are, their evolutionary trajectory is therefore not predictable in detail.

… As a result, unlike the near-equilibrium processes of traditional thermodynamics, complex systems do not forget their initial conditions: they “carry their history on their backs” (Prigogine). Their origin constrains their trajectory.

Those aspects of the environment with which I am systematically interdependent are part of my external structure. As both a biological and social entity, I extend into the world and am embedded in it (the point that both logical and experimental behaviorism missed).

As distributed wholes, complex adaptive systems are virtual governors that give orders to themselves – qua thing, not qua other.

The constraints that wholes impose on their parts are restrictive insofar as they reduce the number of ways in which the parts can be arranged, and conservative in the sense that they are in the service of the whole.

Attractors represent a dynamical system’s organization, including its external structure or boundary conditions.

Attractors provide evidence that the system’s overall organization constrains available alternatives (Brooks and Wiley) such that its behavior is characteristically drawn to certain patterns.

Complex dynamical systems like you and me, however, have an indefinitely large number of properties. Representing each by an axis in state space requires an unvisualizable graph with an astronomical number of dimensions.

Complex systems are often characterized by strange attractors. The strange attractors of seemingly “chaotic” phenomena are therefore often not chaotic at all. Such intricate behaviour patterns are evidence of highly complex, context-dependent dynamic organization.

If a system accessed every point or region in its phase space with the same frequency as every other (that is, randomly), its ontogenetic landscape would be smooth and flat.

A completely flat, smooth initial landscape would portray an object with no propensities or dispositions – that is, with no attractors. It would describe a “system” with no identity, a logical impossibility.

The effects of constraints can therefore be represented as a probability landscape like

Since a system’s external structure can recalibrate its internal dynamics, probability landscapes also incorporate the role of the environment in which a system is embedded.

Since a system’s prior experience constrains its behavior, that history, too, is embodied in its ontogenetic landscape.

The landscape of a dynamical system, by definition, is never static. Although it remains qualitatively the same between phase changes, it continually shifts in response to the system’s interactions with its environment.

When dramatic phase changes occur, the whole attractor regime completely reorganizes as the system undergoes a bifurcation.

Contour of the entire landscape reconfigures in a phase-change bifurcation. The metamorphoses of tadpoles into frogs or caterpillars into butterflies mark such a qualitative transition.

Generative organizing is simultaneously time and context-dependent. There is a built-in one-wayness. The organizing is embedded in an environment, which it in turn influences. The precise path the organizing will take is unpredictable.
