Famous quotes containing the words john and/or mackenzie:
“People named John and Mary never divorce. For better or for worse, in madness and in saneness, they seem bound together for eternity by their rudimentary nomenclature. They may loathe and despise one another, quarrel, weep, and commit mayhem, but they are not free to divorce. Tom, Dick, and Harry can go to Reno on a whim, but nothing short of death can separate John and Mary.”
—John Cheever (1912–1982)
“People sometimes tell me that they prefer barbarism to civilisation. I doubt if they have given it a long enough trial. Like the people of Alexandria, they are bored by civilisation; but all the evidence suggests that the boredom of barbarism is infinitely greater.”
—Kenneth MacKenzie Clark, Baron of Saltwood (1903–1983)
