"#Information is a difference that makes a difference (G. Bateson, 1972, p. 315), and what it ‘‘does’’ or what it means is thus dependent on what is already in place and what alternatives are being distinguished."

(S. Oyama, 2000, p. 3)

Or, as more clearly defined in #Kihbernetics: #Information is the difference between the results of #Knowledge-based #Prediction (function A) and the #Perception (function B) of sensory inputs that will make a difference once integrated into a new knowledge #state of the dynamical (learning) system.
