“barbarians” and “savages.” Though hardly precise Linnaean categories, “barbarians” often denoted a hostile pastoral people who posed a military threat to the states but who might, under certain circumstances, be incorporated; “savages,” on the other hand, were seen as foraging and hunting bands not suitable as raw material for civilization, who might be ignored, killed, or enslaved. When Aristotle wrote of slaves as tools, one imagines that he had in mind “savages” and not all barbarians (for example, Persians).
