Thomas More, Utopia — Chapter 7: Of Their Slaves… (1901)
“ For the most part slavery is the punishment even of the greatest crimes, for as that is no less terrible to the criminals themselves than death, so they think the preserving them in a state of servitude is more for the interest of the commonwealth than killing them, since, as their labour is a greater benefit to the public than their death could be, so the sight of their misery is a more lasting terror to other men than that which would be given by their death. ”
