Our community of scientists is, by definition and by training, rational. Our approach to problems is multidisciplinary and we are used to solving complex issues. By examining and analysing the problems at hand, with the help of eminent specialists in the relevant fields, we can come to certain conclusions and propose solutions, which can then be disseminated throughout our community, worldwide. Thanks to our community, our conclusions and recommendations are heard at the highest political levels such as, for example, during the Nuclear Warfare Seminars prior to the ratification of the Salt II Treaty: to President Reagan through Edward Teller, to President Gorbachev through Yevgeniy Velikhov and through Zhou Guang Zhao to President Deng Xiao Ping. The Nuclear War Seminars that brought the top brains of the two US-USSR superpowers to Sicily to study how to overcome the danger of nuclear holocaust were born thanks to Paul Dirac in the early 1980s. These seminars led Eugene Wigner (father of the Time Theorem) to say that the Berlin Wall began to fall in Erice well before Berlin. It is necessary for all governments to agree that the doors of any laboratory should be open, without exception. Nor should we forget that it is wrong to prohibit studies at home on subjects that others secretly seek to carry out. In the third millennium, it is good to create a scientific culture that teaches us to distinguish Science from Technology so that violence in all its forms (political or economic) can be eradicated from civilised living. And may a Science without secrets and without frontiers with technological applications exclusively aimed at improving the quality of life and defending the dignity of the human species become a reality.
