"To be able to one day change a harsh reality, we need to know how to define what needs to be changed and how to effect change. To cope with situations in life-both personal and public-we need to have a real picture of these situations and of their possible outcomes. We need to know the price of each and who will pay it in the end. To know that every act and every error has consequences. To reduce to a minimum the possibility that someone-the regime, or the press, or the local leadership-will deceive us, cram us with false "facts" that are appropriate to whoever is making use of them. To make quite sure that, in the highest possible percentage of cases, we can make our own decisions and not let someone else think for us. All these things require a constant and precise mapping of reality. In other words, they require information about what exists and what is possible."
