We are socialists because we believe we live now in a world that requires a great deal of thoughtful planning ahead of time. We are socialists because we live in a world that is peculiarly interdependent, and to a degree quite unknown in earlier times. [...] We are socialists because we believe in this kind of world - in this anarchy of nations - we need to have a concept that the great purpose of life is to manage our extraordinary scientific and technological achievements and our resources for the common good. It's not easy and it cannot be the byproduct of a game where everybody seeks the maximum profit for himself, either men or nations in that role.
