“The Communist revolution is the most radical rupture with traditional property relations; no wonder that its development involves the most radical rupture with traditional ideas.”

Why have they “found it hard to counter the appeal of radical ideas promoted by the Islamic State”? To Western leaders such as David Cameron, John Kerry, Joe Biden, Pope Francis, the U.S. Catholic bishops, and a host of others, it is patently obvious that the Qur’an teaches peace and that Islam is a religion of peace. So it ought to be child’s play for these imams in Dagestan to refute the twisted, hijacked version of Islam presented by the Islamic State. Here’s an idea: why doesn’t Barack Obama send Kerry to Dagestan to explain to young Muslims how the Islamic State is misunderstanding and misrepresenting Islam? Or maybe Pope Francis could go there, or he could send some Arabic-speaking Eastern Catholic bishop — say, one who knows that Islam is at its core a peaceful religion and who moves actively to silence and ostracize those who say otherwise — to the Islamic State, straight to Raqqa, to explain to the caliph how he is misunderstanding Islam. That would clear up this problem in a hurry. I volunteer to pay the bishop’s airfare.

The Cornerstone Speech (1861)
Context: But not to be tedious in enumerating the numerous changes for the better, allow me to allude to one other though last, not least. The new constitution has put at rest, forever, all the agitating questions relating to our peculiar institution African slavery as it exists amongst us; the proper status of the negro in our form of civilization. This was the immediate cause of the late rupture and present revolution. Jefferson in his forecast, had anticipated this, as the 'rock upon which the old Union would split'. He was right. What was conjecture with him, is now a realized fact. But whether he fully comprehended the great truth upon which that rock stood and stands, may be doubted. The prevailing ideas entertained by him and most of the leading statesmen at the time of the formation of the old constitution, were that the enslavement of the African was in violation of the laws of nature; that it was wrong in principle, socially, morally, and politically. It was an evil they knew not well how to deal with, but the general opinion of the men of that day was that, somehow or other in the order of Providence, the institution would be evanescent and pass away.
