Critical Instability

The claim that living systems keep themselves at "the edge of chaos" so that tiny inputs (a whisper; a moth's random jink) can redirect the whole organism's future. For Agüera y Arcas it is one of the two ingredients of free will — the other being high-order theory of mind including a model of oneself — and it is selected for because being unpredictable to predators and rivals is itself a survival strategy. Combined with Turing-style injected randomness for sampling counterfactual futures, it is what makes "a model of the future determine what actually happens" without violating physics.
