"For the sake of argument suppose the books and other periodicals were written so as to be prejudicial in favor of the government, and the heads also were coloring what they said." I thought for a minute. "In that case I suppose I would secretly place someone inside the country to interview the people and get a first hand view of the situation. Then I would act on his data." * * * * * He nodded his head. "Yes, the people themselves and the conditions they live in will give you the needed data." He turned a page in the book. "Now suppose that you wished to know if a certain planet was ready to enter into an organization such as the Galactic Federation, what would you do?" "I suppose I'd act as I did before. Place people inside the various areas of the planet to interview and observe. They would bring back the information needed to ascertain whether they would be an asset or a detriment to the organization." I thought to myself that the question was a trifle silly; after all, hadn't science proved that life couldn't exist on the other planets in our system? He relaxed after I answered and his smile was brighter than the previous ones. "Right," he said. "Naturally we had to learn the language first, but now a first-hand check can be made. You see, there is a civilization out there," he raised his hand and swept the sky, "and we have to check to see if this planet is ready to take its place as an adult civilization with the rest of us. "Earth, within a very short time, will be reaching her fingers into space. Once she gets there she will be eligible to join the Galactic Federation." "That's all right," I said, "then we can exchange culture and knowledge with other civilizations." "Yes, if you are eligible to join." "But you said that once we reach space we will be eligible." "Look at it this way," he said. "The main purpose of the Galactic Federation is to promote peace and understanding among the various planets. Earth would have to be prepared to take its place as just another member, and not an important member at that. Earth, you see, is one of the smaller planets and also would be the latest one to join. "In times past some planets have reached space without being fully prepared for what they would find. They still had internal troubles on their own worlds. We had to place them in quarantine until they reached that degree of civilization where they were ready to live in peace. Now we check a planet before it reaches the space-travel stage. We find out the reactions of the inhabitants to certain situations." "What sort of situations?" I asked. "Well, naturally we want to see their artifacts as an indication as to their advancement. We have to know what the average man thinks of space travel and trade with other planets. And their ideas on peace and their feelings towards their fellow men. All are very important.
