@ArchiteuthisFlux responding to a lighthouse is not a bad metaphor for intelligence though, because it actually involves:

(a) observation—what is this lighthouse's pattern?
(b) measurement—what bearing is it...
(c) self-knowledge—...relative to my heading?
(d) external information—where is it on the chart?
(e) correlation—conclude where i am along a line
(f) prediction—where i will be after a period of time
(g) decision-making—is that where i want to be?
(h) action—course correct as needed.
