The acquisition of the information and the use of it in decision making can be separated. The use of acquired information to make a decision is, in the general case, an optimization in an uncertain situation (which is included in Weinberger's theory). For deterministc rule based decisions, the agent can be formalized as an algebra with a set of operations and the state changes when these operations are executed (no optimization applied). The pragmatic information such an agent picks up from a messages is the transformation of the tokens in the message into operations the recipient is capable of.
