Described by William Walton in the English translation as "the sentiments of an enlightened foreigner" (iii) on the abolition of slavery, this text is a memoir by José D'Andrada e Silva, the leading advocate of Brazilian independence in the 1820s, written from exile in Paris and addressed to the government of Brazil. It calls for the gradual abolition of slavery. D'Andrada e Silva calls on the Brazilians, "the only nation, derived from European blood, that still publically and unblushingly trades in African slaves" (15), to abolish the slave trade and work towards the gradual emancipation of the slaves in Brazil.
