However, across physics, biology, and complex adaptive systems, long-term stability appears to depend not on increasing power alone, but on improving efficiency and constraint alignment. This paper proposes the Constraint Principle, a cross-domain framework in which … Continue reading The Constraint Principle: Intelligence, Wisdom, and Efficiency in Cosmological and Civilizational Equilibrium
