I have been greatly encouraged by what I have seen this week. Basic science researchers have been getting to grips with issues which they may not always have considered as aspects of their work. There have also been government ministers and other officials, listening to the natural scientists, to the social scientists, to the NGOs - and I thank them too for entering this very open dialogue. Each and every person here has fully played his or her part. I am especially grateful because the relationship between science and society that we are seeking for the start of a fresh century makes learners of us all.
Science popularisation has to enrich debate and feed a growing exchange on the issues.
Much has been said about public disenchantment with science. What saddens me most is the disenchantment of many young people. That is the best way to build justice and security, to facilitate the transition from a culture of force and confrontation to a culture of tolerance and dialogue - a culture of peace. And for this to happen on a massive scale, we need a new commitment at all levels. First and foremost, the outcome of this Conference must impact directly on national policies.
