“There are people who think the natives of Dahomey very barbarous, because, on the accession of a king, they believe it well to sail a little vessel in human blood in order to tell the fortunes of the new monarch. Now the blood of a thousand slaves is enough for the purpose, whilst in our so-called civilized countries, the great powers, for prestige, or power, or revenge, will shed the blood, not of a thousand, but of 10,000, of 500,000, of millions of persons, enough to make bloody the mightiest river of Europe or America. And yet we dare to treat as barbarians the people of Dahomey.”
Frédéric Passy, from a speech promoted widely in its day (late 19th century) by The Peace and Arbitration Society.
