Consciousness as Thermodynamically Constrained Order
Entropic theories explain consciousness through its relation to the Second Law of Thermodynamics. Peter Lugten argues that the local drop in entropy consciousness achieves must be paid for by permanently deleting the computations that produced it, which is why experience seems nonphysical; Carlos van Hamme ties awareness to coherence crossing a threshold in neuronal microtubules; and Yifeng Chen and J. W. Sanders model consciousness as entropy reduction, selecting one conscious scenario from many possible ones.

What consciousness is
Consciousness is a physical process defined by its relation to entropy. For Lugten it is an evolved computational emergence that does work and radiates heat; for van Hamme it is a threshold regime of a universal entropic–coherence field; for Chen and Sanders it is the reduction of uncertainty by choosing one internal scenario.
Mind and body
The brain always generates consciousness, but thermodynamic constraints shape how. Lugten holds that the explanatory gap is real and permanent because the Second Law forces deletion of the steps that produced experience, giving consciousness its deceptive appearance of being nonphysical.
Mechanism
Entropy balance. Lugten’s Landauer-like principle requires that any local decrease in entropy from conscious emergence be offset by permanent erasure of the computation’s steps; van Hamme’s mechanism is coherence crossing a microtubular threshold.
Core claims
- The explanatory gap cannot be bridged because the computations that produce consciousness are erased to repay an entropy debt (Lugten).
- Conscious awareness arises only when coherence in microtubules passes a threshold, with sleep and anesthesia as dips below it (van Hamme).
- Van Hamme cites EEG discontinuities, terahertz vibrational modes of microtubules and selective anesthetic binding as support.
- Consciousness as Entropy Reduction can be simulated with a simple mathematical model of scenario selection (Chen and Sanders).
Criticisms
The authors disagree on key points: Lugten says conscious emergence proves we are not predetermined, while van Hamme calls agency deterministic yet adaptive. Lugten’s claim that information can be neither created nor destroyed sits awkwardly with his required ‘permanent deletion’ of computational steps.
Implications
- AI consciousness: Unlikely
- Lugten holds that only living organisms can repay the entropy debt, which rules out conscious machines, and van Hamme ties awareness to biological microtubules.
- Survival beyond death: No
- Since consciousness here is thermodynamic work done by a living brain, it ends when that work stops.
- Meaning and purpose: Humanistic only
- Lugten defends genuine free will within a naturalist frame, and van Hamme treats consciousness, choice and value as natural expressions of a physical substrate rather than signs of cosmic purpose.
- Virtual immortality: Unlikely
- If consciousness is restricted to evolving organisms that pay an entropy debt, a digital copy would not be conscious.
