"The revival of fanaticism and Mediaeval attitudes, the emergence of parties based on racial perceptions and the increase in violence bear witness to the fact that respect for others who are different, which is a feature of advanced societies, has not yet been fully achieved."
La survivance de l' esprit d' intolérance, de type moyenâgeux, la création de partis reposant sur des conceptions racistes, la montée de la violence, attestent que le respect de la différence, qui est le signe distinctif des sociétés développées, ne s' est pas totalement imposé.
