Conceived as a contribution to the nineteenth-century "expiation" (5) of Europe's involvement in the slave trade, this short comparison of slave and free colonial societies is based on the author's stay in the Caribbean. He describes French indifference to the problem of slavery as the result of ignorance, and attempts to educate public opinion by publishing his impressions of French Caribbean society and the British apprenticeship project. He concludes that France should learn from Britain's errors, abolishing slavery gradually to accustom both the slaves and French public opinion to the idea of emancipation.
