The traditional method to create barbarians is for some well-meaning but naive star-travelers to give starship technology to a primitive planet-bound species. The barbarians then proceed to raid all the civilized planets in range, like space-going vikings. The civilized military will (hopefully) eventually put down the barbarians but the war will be long, bloody, and costly. After the barbarian wars, the star-traveling civilization outlaws such technology transfers. Assuming the civilization actually survives the barbarian onslaught.
W hile Polynesian navigators were internalising stories to help them find their way at sea, over many centuries Western astronomers gradually came to realise that at each step in passing from the direct visual experience of a star or planet to an isolated entry in a logbook, there are possibilities for error, misinterpretation, personal bias and confusion. Hence, as Western astronomy became more complex – as it evolved into a science in the modern sense – its practitioners worked hard to reduce the human role to more machine-like actions.
