It is well known, of course, that most organisms feed directly or indirectly off the stream of energy that arrives as photons from the Sun. Only by cycling energy and matter through its metabolic network is an organism able to stave off the decay toward thermal equilibrium—that is, death. ![]() ![]() ScienceSchneider and Sagan, however, contend that a “thermodynamic imperative” to efficiently reduce gradients provides the key to understanding such processes as the evolution of species (“Genetics is not enough,” they write) and the development of ecosystems. At times the authors give the second law of thermodynamics a Darwinian status, as in chapter 17, where one reads that it “ ‘selects’ those systems best able to reduce gradients under given constraints.” In the book’s final chapter, Schneider and Sagan suggest that tapping into thermal gradients is not just a necessary condition for life but ultimately the explanation of life’s purposeful behavior. These ideas are neat, but does the evidence really support them? Although it is true that life, to persist in its state of low entropy, must continually degrade the free energy of its surroundings, it is not clear that a dictate to do so with maximum efficiency is really what drives the biosphere’s evolving complexity. Physicists might also quibble with the authors’ promotion of the slogan “nature abhors a gradient” as a kind of distillation of the second law. “The world changes when you view it through the lens of irreversible gradient reduction, rather than mere entropy increases and decreases,” they write.

MathematicsThe authors envisage “a thermodynamics in which the spontaneous degradation of gradients is paramount.” Even if we leave aside gravity, which the authors acknowledge does not quite fit their paradigm, it should be clear that nature does not always abhor a gradient. Entropy is ultimately a more useful concept than gradient reduction for explaining why an oil droplet placed in water does not diffuse while an ink droplet does.
