According to #HvFoerster, the *integrated functional circuit* for #cognition requires these three faculties:

1️⃣ #Perception - without which the system cannot detect and internally represent environmental regularities,
2️⃣ #Memory - without which the system has only throughput (cannot learn)
3️⃣ #Prediction - or the faculty of drawing #inferences, without which *perception degenerates into #sensation and memory into #recording*.
