- Paramedic #2: I feel like that little Dutch boy trying to plug holes with my fingers while the whole dam collapses around me.
- Dr. Henry 'Indiana' Jones, Jr.: I met a Dutch boy like you once, German actually. He was in Africa during the first World War.
- Dr. Henry 'Indiana' Jones, Jr.: [narrating] Through a stroke of good luck I was made a captain in the Belgian army. Then, through a stroke of bad luck I was send on an impossible mission across the heart of Africa.
- Albert Schweitzer: Reverence is a state of mind, not a set of rules. All it requires is everything be done in deep awareness. Good is whatever promotes life. Evil is whatever destroys it. From there you make your own decisions.
- Dr. Henry 'Indiana' Jones, Jr.: That little girl with the gunshot wound, will she make it?
- Paramedic #2: Well, it's been touch and go. We've done all we can for her. We'll just have to wait and see if the vital signs stabilize. What seems to be the problem?
- Dr. Henry 'Indiana' Jones, Jr.: Rather trivial compared to that. My foot's swollen. I was stung on the toe by a bee.
- Remy: Damn the French. Don't they know we are fighting on the same side?
- Indiana Jones: We'll make do without them.
- Zachariah Sloat: Listen to me, sonny, if you think you're gonna rig my boat with them explosives, you're as crazy as a rat in a tin can.
- Indiana Jones: You're German.
- Albert Schweitzer: You're perceptive.
- Indiana Jones: Then I'm your prisoner?
- Albert Schweitzer: I'm sorry, I can't accept your surrender. We simply haven't the facilities.
- Albert Schweitzer: [Indy is threatening to blow up the boat and its cargo] And kindly blow yourself up away from my dock, I need it in one piece.
- Indiana Jones: Why didn't you say something when you boarded the boat?
- Joseph: You seemed in no mood to listen. Besides, I had more immediate concerns. Like not being blown into small bloody fragments of my former self. I do apologize for punching your face so profoundly. I am dazed with regret.
- Indiana Jones: It's alright. I forgive you.
- Joseph: [smiles] I am greatly relieved.
- Indiana Jones: It figures I'd find you in bed. What's this slacking off?
- Remy: The doctor told you I lost two toes?
- [Indy nods]
- Remy: That leaves eight. More than enough to kick your butt up around your ears.
- Indiana Jones: But... what can you possibly hope to accomplish? This whole continent is festering with disease. What you're doing, is like trying to hold back a tidal wave.
- Albert Schweitzer: I see it more as, ehm, gathering pebbles from a beach. I couldn't carry them all, of course, but I can certainly carry a handful each day. And each pebble I save has value. Well, I saved you, nicht wahr?
- Dr. Henry 'Indiana' Jones, Jr.: [narrating] Sometimes our light goes out, but it's blown again into flame by an encounter with another human being. Each of us owes the deepest thanks to those who have rekindled this inner light. Albert Schweitzer said that. As I stood on the dock, watching Sweitzer and his wife be taken back to Europe as prisoners of war, I reflected on the very deep truth of what Remy had said. He'd been right all along: it was a fool's errand.
- Dr. Henry 'Indiana' Jones, Jr.: [cut back to the present day Indy in the hospital] The hospital was reclaimed by the jungle. It vanished entirely as if it had never existed. But after the war, Schweitzer came back to Africa and started again. He built another hospital, bigger and better than the last. He never stopped gathering those pebbles.
