Some clarity on entailment in Robert Rosen’s thinking, from Judith Rosen in a quick chat:
> “Entails” can be a synonym for “could lead to”. Entailment and causality are linked concepts, the difference being that causality is “what does happen” and entailment refers to “what COULD happen”. Nothing can happen that isn’t entailed. That’s the bottom line. That’s the stuff of “miracle” and paradox and supernatural magic… If something is deemed to be impossible and it happens then the model that predicted it was impossible is at fault. Cuz obviously if it happens in the universe, it’s entailed by the universe and is not supernatural at all; it’s “natural”.
In brief. David Ing.
