The Biological Brain as a Transition Point: The Reflexive Turn in Natural Intelligence
The emergence of the human brain marks not merely another step in biological evolution , but a fundamental shift in how evolution itself is enacted. This shift can be understood as a “ reflexive turn ”—a moment in which natural intelligence becomes capable of recognizing, modeling, and applying the very principles that have always governed it. At the center of this transformation lies what may be called the Principle of Optimality : a universal tendency for systems to organize, adapt, and persist in ways that maximize functional coherence within constraints. This principle has operated since the earliest formations of matter and life. Molecules assemble, cells regulate, and ecosystems stabilize without awareness of the laws they embody. The principle does not require observation to function; it is intrinsic to the dynamics of physical and biological systems. However, with the emergence of the human brain, something qualitatively new appears. For the first time, a system ar...
