P6-the sociological imagination enables us to grasp history and biography and the relations between the two within sociey.

~ C. Wright Mills

Once war was considered the business of soldiers, international relations the concern of diplomats. But now that war has become seemingly total and seemingly permanent, the free sport of kings has become the forced and internecine business of people, and diplomatic codes of honor between nations have collapsed. Peace in no longer serious; only war is serious. Every man and every nation is either friend or foe, and the idea of enmity becomes mechanical, massive, and without genuine passion. When virtually all negotiation aimed at peaceful agreement is likely to be seen as 'appeasement,' if not treason, the active role of the diplomat becomes meaningless; for diplomacy becomes merely a prelude to war an interlude between wars, and in such a context the diplomat is replaced by the warlord.

p5-what they need..is a quality of mind that will help them to use information and to develop reason in order to achieve lucid summations of what is going on in the world and of what may be happening within themselves. It this this quality..what may be called the sociological imagination.

~ C. Wright Mills

Freedom is not merely the opportunity to do as one pleases; neither is it merely the opportunity to choose between set alternatives. Freedom is, first of all, the chance to formulate the available choices, to argue over them -- and then, the opportunity to choose.
