Published in eight languages (English, Dutch, French, German, Italian, Portuguese, Spanish and Swedish), this Quaker pamphlet addressed to the inhabitants of Europe promotes the cause of abolitionism through a shared sense of Christian duty and brotherhood - not only with "our Continental neighbours", but with the people of Africa: "The same feelings which lead us to consider the natives of France, of Spain, of Holland, of Portugal, and of the other nations of Europe, as our brethren, induce us to extend this endearing appellation to the inhabitants of Africa" (5). It encourages supporters of abolition to inform themselves and those around them about the iniquity of the slave trade, and to "combine their efforts in this righteous cause" (15).
