Knowledge is indivisible. When people grow wise in one direction, they are sure to make it easier for themselves to grow wise in other directions as well. On the other hand, when they split up knowledge, concentrate on their own field, and scorn and ignore other fields, they grow less wise - even in their own field.
Isaac AsimovIt is quite clear that as long as the nations of the world spend most of their energy, money, and emotional strength in quarreling with words and weapons, a true offensive against the common problems that threaten human survival is not very likely. A world government that can channel human efforts in the direction of the great solutions seems desirable, even essential. Naturally, such a world government should be a federal one, with regional and local autonomy safeguarded and with cultural diversity promoted.
