It were superfluous to enlighten the matter more thoroughly by mentioning the numberless instances of innocent persons who have confessed themselves guilty from the agonies of torture; no nation, no age, but can mention its own; but men neither change their natures nor draw conclusions.

What kind of right can that be which men claim for the slaughter of their fellow-beings? Certainly not that right which is the source of sovereignty and of laws.
