'''Resilience''' is the capacity of a [[Systems|system]] to absorb disturbance and reorganize so as to retain essentially the same function, structure, and identity. It is distinct from both [[Robustness|robustness]] (maintaining function without reorganizing) and stability (returning to the original state). A resilient system may be dramatically altered by a disturbance and still survive as a functioning system; a merely robust system resists alteration.

The concept originates in ecology — C.S. Holling's 1973 paper distinguished engineering resilience (how fast a system returns to equilibrium) from ecological resilience (how large a disturbance a system can absorb before flipping to an alternative state). The distinction matters: engineering resilience is optimized by efficiency; ecological resilience is maintained by redundancy, diversity, and [[Negative Feedback|feedback richness]] — properties that look wasteful from an efficiency standpoint and are therefore systematically destroyed by optimization processes. This is why highly optimized systems are fragile: they have traded resilience for efficiency, a trade that is invisible until the disturbance arrives.
