What Does Entropy Mean Outside Physics?
Entropy has a precise technical meaning in thermodynamics. For isolated systems, the Second Law constrains total entropy from decreasing over time. Open systems can sustain local organization through continuing exchanges of energy and matter with their surroundings. DCI draws philosophical attention to this distinction when considering maintenance, impermanence, and the cost of sustaining finite forms.
Neighboring vocabularies include open systems, nonequilibrium thermodynamics, dissipative structures, the historical term negentropy, and the looser social-science metaphor social entropy. DCI uses these as points of comparison. Its ethical claims arise from its account of agency and consequence, not from thermodynamic law itself.
This page explains DCI terminology in ordinary language. Canonical formulations remain in the DCI corpus.
Open systems, negentropy, and the cost of maintaining order
Living and constructed systems persist through exchange, work, repair, and replenishment. The historical term negentropy has been used to describe the maintenance of organization in living systems, while nonequilibrium thermodynamics provides a more precise account of systems sustained away from equilibrium through flows of energy and matter. DCI takes the maintenance problem as philosophically significant: continued coherence has conditions, consumes capacity, and leaves consequences.
The comparison has limits. Thermodynamic entropy is measurable within physical theory. DCI's ethical thermodynamics is an analogy for examining maintenance, drift, consequence, and finite duration.
Physical and philosophical use
Thermodynamic entropy belongs to physics. DCI keeps moral value outside thermodynamic measurement. Its phrase ethical thermodynamics is a philosophical analogy that directs attention toward expenditure, maintenance, loss, transformation, and finite duration.
That distinction matters because physical description leaves moral preference unresolved. Entropy supplies part of DCI's descriptive architecture. Ethical commitments enter when the doctrine asks how agency should meet other agency.
Entropy and maintenance
The practical value of the analogy appears wherever a form persists through recurring work. Buildings need repair. Records require preservation. Bodies need rest and care. Agreements need review when circumstances change. Neglected maintenance can migrate into later cost, emergency labor, exhaustion, or failure.
Entropy and impermanence
DCI uses impermanence as the broader recognition that finite forms change. Entropy gives that recognition a material orientation. Together they direct attention toward what requires care, what is drifting, what can be repaired, and what may need to be released when continued maintenance has ceased to preserve a viable form.
