I think America has a responsibility to maintain its leadership in technology and its moral leadership in the world, to explore, to seek knowledge.

After Apollo 17, America stopped looking towards the next horizon. The United States had become a space-faring nation, but threw it away. We have sacrificed space exploration for space exploitation, which is interesting but scarcely visionary.

Today, we are on a path of decay. We are seeing the book close on five decades of accomplishment as the leader in human space exploration.

When you head on out to the Moon, in very short order, and you get a chance to look back at the Earth, that horizon slowly curves around in upon himself, and all of sudden you're looking at something that is very strange, but yet is very, very familiar, because you're beginning to see the Earth evolve.

We looked too long for God and truth through words alone. The fruit for humanity has been rather limited, it seems to me - especially when I observe every day the extraordinary amount of unhappy and angry people in well educated and 'religious' countries.

Stories of all lengths and depths come from different parts of the cave. For a novel, you must lay in mental, physical and spiritual provision as for a siege or for a time of hectic explosions, while a short story is, or can be, a steady, timed flame like the lighting of a blow lamp on a building site full of dry tinder.

War used to be something you could stand on the nearby hill and watch. Now we have total war; everybody's in it. We have total economics as well. Everything affects everybody. The Malaysian currency shakes, and people around the world are seriously affected.

When we obey God, we're not doing it for God... we're doing it for ourself. Because God takes pleasure when we're happy.
