The senses make a more vivid impression on the mind than systematic thought…. Even the man who planned the operation and now sees it being carried out may well lose confidence in his earlier judgment…. War has a way of masking the stage with scenery crudely daubed with fearsome apparitions. Once this is cleared away, and the horizon becomes unobstructed, developments will confirm his earlier convictions—this is one of the great chasms between planning and execution. —Carl von Clausewitz, ON WAR (1780–1831)
