"Let me cite one of the most eloquent contemporary passages on human freedom. It comes, not from the literature of America, but from this country, from one of the greatest writers of the 20th century, Boris Pasternak, in the novel Dr. Zhivago.' He writes: "I think that if the beast who sleeps in man could be held down by threats -- any kind of threat, whether of jail or of retribution after death -- then the highest emblem of humanity would be the lion tamer in the circus with his whip, not the prophet who sacrificed himself. But this is just the point -- what has for centuries raised man above the beast is not the cudgel, but an inward music -- the irresistible power of unarmed truth. The irresistible power of unarmed truth. Today the world looks expectantly to signs of change, steps toward greater freedom in the Soviet Union. We watch and we hope as we see positive changes taking place. There are some, I know, in your society who fear that change will bring only disruption and discontinuity, who fear to embrace the hope of the future -- sometimes it takes faith. It's like that scene in the cowboy movie Butch Cassidy and the Sundance Kid, which some here in Moscow recently had a chance to see. The posse is closing in on the two outlaws, Butch and Sundance, who find themselves trapped on the edge of a cliff, with a sheer drop of hundreds of feet to the raging rapids below. Butch turns to Sundance and says their only hope is to jump into the river below, but Sundance refuses. He says he'd rather fight it out with the posse, even though they're hopelessly outnumbered. Butch says that's suicide and urges him to jump, but Sundance still refuses and finally admits, "I can't swim. Butch breaks up laughing and says, "You crazy fool, the fall will probably kill you. And, by the way, both Butch and Sundance made it, in case you didn't see the movie. I think what I've just been talking about is perestroika and what its goals are."
