Famous quotes containing the words shared, secret and/or keys:
“What I wanted was to create thoughtful citizens—people who believed they could live interesting lives and be productive and socially useful. So I tried to create a community of children and adults where the adults shared and respected the children’s lives.”
—Deborah Meier (b. 1931)
“I’ve been cursed for delving into the mysteries of life. Perhaps death is sacred, and I’ve profaned it. Oh, what a wonderful vision it was. I dreamed of being the first to give to the world the secret that God is so jealous of, the formula for life. Think of the power, to create a man. And I did, I did it, I created a man. And who knows, in time I could have trained him to do my will. I could have bred a race, I might even have found the secret of eternal life.”
—William Hurlbut (1883–?)
“McCoy: That shark’s been following us ever since the surgeon died, waiting for the burial. Couldn’t I have a musket to shoot it, sir?
Fletcher Christian: Take the deck, McCoy. I’ll get the keys to the arms chest.
McCoy: Get two muskets, sir. I’d like to shoot that shark on board.”
—Talbot Jennings (1896–1985)
