the violence and the turmoil?

Finally Don Barzini sought to bring the meeting to an end. "That's the whole matter then," he said. "We have the peace and let me pay my respects to Don Corleone, whom we all have known over the years as a man of his word. If there are any more differences we can meet again, we need not become foolish again. On my part the road is new and fresh. I'm glad this is all settled."
  Only Phillip Tattaglia was a little worried still. The murder of Santino Corleone made him the most vulnerable person in this group if war broke out again. He spoke at length for the first time.
I've agreed to everything here, I'm willing to forget my own misfortune. But I would like to hear some strict assurances from Corleone. Will he attempt any individual vengeance? When time goes by and his position perhaps becomes stronger, will he forget that we have sworn our friendship? How am I to know that in three or four years he won't feel that he's been ill served, forced against his will to this agreement and so free to break it? Will we have to guard against each other all the time? Or can we truly go in peace with peace of mind? Would Corleone give us all his assurances as I now give mine?"
  It was then that Don Corleone gave the speech that would be long remembered, and that reaffirmed his position as the most far-seeing statesman among them, so full of common sense, so direct from the heart; and to the heart of the matter. In it he coined a phrase that was to become as famous in its way as Churchill's Iron Curtain, though not public knowledge until more than ten years later.
For the first time he stood up to address the council. He was short and a little thin from his "illness," perhaps his sixty years showed a bit more but there was no question that he had regained all his former strength, and had all his wits.
What manner of men are we then, if we do not have our reason," he said. "We are all no better than beasts in a jungle if that were the case. But we have reason, we can reason with each other and we can reason with ourselves. To what purpose would I start all these troubles again, the violence and the turmoil? My son is dead and that is a misfortune and I must bear it, not make the innocent world around me suffer with me. And so I say, I give my honor, that I will never seek vengeance, I will never seek knowledge of the deeds that have been done in the past. I will leave here with a pure heart.
Let me say that we must always look to our interests. We are all men who have refused to be fools, who have refused to be puppets dancing on a string pulled by the men on high. We have been fortunate here in this country. Already most of our children have found a better life. Some of you have sons who are professors, scientists, musicians, and you are fortunate. Perhaps your grandchildren will become the new pezzonovanti. None of us here want to see our children follow in our footsteps, it's too hard a life. They can be as others, their position and security won by our courage. I have grandchildren now and I hope their children may someday, who knows, be a governor, a President, nothing's impossible herein America. But we have to progress with the times. The time is past for guns and killings and massacres. We have to be cxmning like the business people, there's more money in it and it's better for our children and our grandchildren.
