Greek philosopher Aristotle justified this practice by claiming that humanity is divided into two classes, that of the masters and that of the slaves, with the former having a natural right to command, whereas the latter were simply born to obey.
Kreeka filosoof Aristoteles õigustas orjapidamist, väites, et inimkond on jaotatud kaheks klassiks, isandateks ja orjadeks, ning et isandatel on loomulik õigus käsutada, orjad aga ongi lihtsalt sündinud kuuletuma.
