Today, UNESCO's message has never been more important. We must create holistic policies that are capable of addressing the social, environmental and economic dimensions of sustainable development. This new thinking on sustainable development reaffirms the founding principles of the Organization and enhances its role: UNESCO is known as the "intellectual" agency of the United Nations. At a time when the world is looking for new ways to build peace and sustainable development, people must rely on the power of intelligence to innovate, expand their horizons and sustain the hope of a new humanism. UNESCO exists to bring this creative intelligence to life; for it is in the minds of men and women that the defences of peace and the conditions for sustainable development must be built.
