![]() Nature’s Plan for Humankind Part 1. Metabolic Metaphysics
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. 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.
