The entrenched humanitarians of an older generation might deplore, as Lord Denman did in 1848, the fact that public opinion on the subject of slavery had suffered "a lamentable and disgraceful change". They might note as evidence of a narrowing of sympathy the remark of the Economist of July 25, 1846, that "the duty of England is to its own subjects, not to the natives of Africa or the slaves of the Brazils" and its yet more forthright assertion on February 26th that the slave trade was "the only practical mode which has yet been discovered by which a communication can be opened and maintained between Africa and the civilized world".Context: Parliament abolished the slave trade in 1807 and abolished slavery everywhere in the Empire in 1833. The issue here, as Burn notes, was the future of the West Africa Squadron, which (per Wiki), "[b]etween 1808 and 1860, ... seized approximately 1,600 slave ships and freed 150,000 Africans who were aboard."
ETA: Off-topic but not perhaps enough for a separate post so I'll stick it here. I was at the Boston Review site just now and on their "most read" list there's a piece by James Galbraith from 2003 arguing the JFK-had-ordered-a-withdrawal-from-Vietnam thesis. I didn't take the time to read it, just scrolled through, but was interested given the persistent harping on this point by a particular Crooked Timber commenter who doesn't seem to be posting there anymore. Call me a snob or something, but a lengthy piece by James Galbraith makes me take notice a bit more than a pseudonymous blog commenter does. Not expressing a view on the substance.
