 This paper proposes a new principle for explaining how biological systems can maintain order despite their inherent tendencies, towards disorder. It suggests that the system's behavior can be explained through a combination of two principles, the slaving principle and the principle of least action. The slaving principle refers to the idea that the system will follow external forces, while the principle of least action is based on the concept of variational free energy minimization. When these two principles are combined, they produce a solution that is equivalent to the information bottleneck method, which has been used to study the structure of the brain. This approach has proven successful in understanding the function of the brain, and could potentially be applied to other areas such as molecular or evolutionary biology.
