"[T]he world is an information pump, evolving states by causing transitions from one state to another." #readingToday

What jumps out from the simple formulations above is not the technical details, which are tragically simplified here, though certainly have their own beauty, but rather the underlying information structure of the relations themselves. It suggests that the world is in fact a kind if information pump, evolving states (which are measures of information) by causing transitions from one state to another. Just as the absorption of a photon in a laser would cause a change of state from one level to another, so the absorption of a message (another measure of information) from a sender would cause a change of knowledge state in the receiver. This is computation not by analogy, but by 'digilogy.'
