Explain the concept of functional stability in physical systems.

Functional stability in physical systems refers to the ability of a system to maintain its intended function or purpose despite external or internal changes. It suggests that a system is able to adapt and self-regulate in order to continue performing its designated function. This concept is often applied in the field of philosophy of mind, where functionalists argue that mental states are defined by their functional roles or contributions to the overall cognitive system. In this context, functional stability implies that mental states can persist and remain meaningful even if there are changes in the underlying physical processes or structures that give rise to them.
