“Under a government which imprisons any unjustly, the true place for a just man is also a prison… the only house in a slave State in which a free man can abide with honor.”

Referring to the lack of established culture and the established institution of slavery in the United States, in "Review of Seybert’s Annals of the United States", published in The Edinburgh Review (1820)
Context: In the four quarters of the globe, who reads an American book? Or goes to an American play? or looks at an American picture or statue? What does the world yet owe to American physicians or surgeons? What new substances have their chemists discovered? Or what old ones have they advanced? What new constellations have been discovered by the telescopes of Americans? Who drinks out of American glasses? Or eats from American plates? Or wears American coats or gowns? or sleeps in American blankets? Finally, under which of the old tyrannical governments of Europe is every sixth man a slave, whom his fellow-creatures may buy and sell and torture?

Context: We never can have a true view of man unless we have a love for him. Civilisation must be judged and prized, not by the amount of power it has developed, but by how much it has evolved and given expression to, by its laws and institutions, the love of humanity. The first question and the last which it has to answer is, Whether and how far it recognises man more as a spirit than a machine? Whenever some ancient civilisation fell into decay and died, it was owing to causes which produced callousness of heart and led to the cheapening of man's worth; when either the state or some powerful group of men began to look upon the people as a mere instrument of their power; when, by compelling weaker races to slavery and trying to keep them down by every means, man struck at the foundation of his greatness, his own love of freedom and fair-play. Civilisation can never sustain itself upon cannibalism of any form. For that by which alone man is true can only be nourished by love and justice.
