Definition information/Pinker: a relationship between two things that are caused by a lawful procedure - E.g. embodied info: age rings of a tree - but they were not even produced by the growth.
Information is nothing special - it can be found everywhere where a cause has an effect - Searle would say, it cannot be found, only we can find it, because we must first fill it with meaning - Pinker ditto - symbol: transmits info and makes something happen.
