Entropy

The old science of thermodynamics assigns to nature the tendency to self disorganizeto deconstruct complex structures and processes spontaneously.

The ideas swirling around complexity theory seem to amount to a skirting of the Second Law of Thermodynamics. The hallowed Second Law declares all of nature to be running down, falling apart, inexorably drifting toward equilibrium—away from organized complexity. Mountains erode, stars burn out, organisms die and decay, and the distinguishing features of these physical forms dissipate as their materials get recycled. Potential energy gets used up, and entropy, or disorganization, increases. The world ultimately drifts toward a state of homogeneous featurelessness. This is the transience of the empirical world.

Supposing that something must be increasing while events trend toward equilibrium, physicists have given that thing the name entropy. The end result of any natural process will be a state of equilibrium, a state of maximum disorganization, maximum entropy. The concept of increasing entropy (unless a complex form is actively maintained) is a canonical foundation of the scientific understanding of nature.

Applied to the scale of the universe as a whole, the Second Law predicts an eventual demise, dubbed the "heat death" by physicists. Given enough time, the universe will devolve to a state of maximum equilibrium, in which every potential source of energy will have exhausted itself. Every discernable thing will lose its distinguishing features, and its material constituents will distribute themselves evenly throughout the cosmos. The Second Law sentences the universe to death by entropy.

But the Second Law is a curious description of nature, because, among other things, it relies fundamentally on the concept of a "closed system," an imaginary box cut out of nature that is perfectly isolated from outside influences. In other words, in fairness to the Second Law, it applies, strictly speaking, only inarguably to closed systems, even though "openness" does not guarantee that any particular physical system will be shielded from the pull of entropy. These qualifiers aside, a closed system is an abstract construct. It does not exist in nature. As a result, the Second Law must be treated as contingent. The ideal of the closed system to which it applies is a fiction. In nature energy always leaks into or out of any defined volume of space. As science has done with phlogiston and ether, it can discard the extraneous notion of "closed system" without selling nature short. Nature is of a whole. And within that whole, entropic—tearing down—and anti-entropic—building up—processes operate side by side.

Trying to stay loyal to the Second Law, scientists labor to account for nature's observed ability to manufacture systems that proceed actively away from equilibrium, spontaneously gaining in complexity and shedding entropy. And these labors have led to the development of complexity theory. Some long-lived structures, such as spiral galaxies, persist in states of disequilibrium for many millions of years, in seemingly stark defiance of the Second Law. Theorists have proposed terms such as "extropy" or "negentropy" to name the attribute of a system that increases as the system grows in complexity. (These terms have not caught on very extensively.) So the physical world can be imagined as being governed by a tension between entropy and self organization—or extropy or negentropy. Organization and disorganization are equally observable tendencies in nature.

By developing complex systems theory, science is coming to grips with the paradox of a natural world that obeys both the Second Law and flaunts its ability to outrun the law. Science tells us that, despite apparent violations or bendings of the Second Law, that the Law should remain on the books because every anti-entropic process—every self-organizing complex system—draws energy from a source outside of itself, so that the total system that constitutes both the anti-entropic process and its energy source does predictably increase in entropy. But the question remains as to why nature would construct complex structures and retard their degradation by enlisting anti-entropic processes in the first place. From what law of physics does this capacity issue?

 

In the light of science’s new enthusiasm for vitalism, albeit a vitalism stripped of any metaphysical "life energy" but still granting nature mysterious powers, the psychology of science suffers from cognitive dissonance. It observes that nature tends spontaneously to degrade organized structures into simpler components while simultaneously using those simple components to build up complex structures. So where do nature’s loyalties lie, in the building up or in the tearing down? Complexity or entropy? And how does she decide when and where to construct and when and where to destruct? The dilemma suggests a theoretical impasse. But the impasse can be resolved by retaining both tendencies in their full expression and linking them in a feedback relationship of mutual dependence. What is needed to break through this impasse is a meta-concept that encompasses both tendencies and locates each operationally relative to the other, in a loop. Such an overarching concept is provided by the biological sciences and is called metabolism.
