Though you may have known clever men who were indolent, you never knew a great man who was so; and when I hear a young man spoken of as giving promise of great genius, the first question I ask about him always is, Does he work?
Major Strasser: You give him (Rick Blaine) credit for too much cleverness. My impression was that he's just another blundering American. Captain Renault: We musn't underestimate American blundering. I was with them when they blundered into Berlin in 1918.
There was once a man, Harry, called the Steppenwolf. He went on two legs, wore clothes and was a human being, but nevertheless he was in reality a wolf of the Steppes. He had learned a good deal of all that people of a good intelligence can, and was a fairly clever fellow. What he had not learned, however, was this: to find contentment in himself and his own life.
Every civilization rests on a set of promises. . . . If the promises are broken too often, the civilization dies, no matter how rich it may be, or how mechanically clever. Hope and faith depend on the promises; if hope and faith go, everything goes.
Herbert Sebastian Agar (1897 - 1980)
